    Full Text Available A 48-year-old man with a history of splenic artery pseudoaneurysm requiring transarterial embolization 3 months earlier presented to the emergency department with abdominal pain and fever. Computed tomography showed evidence of embolization coil fragments within the gastrointestinal tract. Upper endoscopy showed a large gastric ulcer with numerous embolization coils extruding into the gastric lumen. The patient underwent partial gastrectomy, distal pancreatectomy and resection of the splenic artery pseudoaneurysm. This case illustrates a rare delayed complication of transarterial embolization of a splenic artery pseudoaneurysm.

    Full Text Available Introduction. Splenic artery Pseudoaneurysm, a complication of chronic pancreatitis, presenting as massive hematemesis is a rare presentation. Case Report. We present a case of 38-year-old male admitted with chief complaints of pain in the upper abdomen and massive hematemesis for the last 15 days. On examination there was severe pallor. On investigating the patient, Hb was 4.0 gm/dL, upper GI endoscopy revealed a leiomyoma in fundus of stomach, and EUS Doppler also supported the UGI findings. On further investigation of the patient, CECT of the abdomen revealed a possibility of distal pancreatic carcinoma encasing splenic vessels and infiltrating the adjacent structure. FNA taken at the time of EUS was consistent with inflammatory pathology. Triple phase CT of the abdomen revealed a splenic artery pseudoaneurysm with multiple splenic infarcts. After resuscitation we planned an emergency laparotomy; splenic artery pseudoaneurysm densely adherent to adjacent structures and associated with distal pancreatic necrosis was found. We performed splenectomy with repair of the defect in the stomach wall and necrosectomy. Postoperative course was uneventful and patient was discharged on day 8. Conclusion. Pseudoaneurysm can be at times a very difficult situation to manage; options available are either catheter embolisation if patient is vitally stable, or otherwise, exploration.

  3. Idiopathic Splenic Artery Pseudoaneurysm Rupture as an Uncommon Cause of Hemorrhagic Shock

    Full Text Available Splenic artery pseudoaneurysms are infrequently encountered but critical to recognize. Limited literature to date describes associations with pancreatitis, trauma, and rarely peptic ulcer disease. Hemorrhage and abdominal pain are the most common manifestations. There is typically overt gastrointestinal blood loss but bleeding can also extend into the peritoneum, retroperitoneum, adjacent organs, or even a pseudocyst. Most patients with ruptured splenic artery pseudoaneurysms present with hemodynamic instability. Here, we describe a patient recovering from acute illness in the intensive care unit but with otherwise no obvious risk factors or precipitants for visceral pseudoaneurysm. He presented with acute onset altered mental status, nausea, and worsening back and abdominal pain and was found to be in hypovolemic shock. The patient was urgently stabilized until more detailed imaging could be performed, which ultimately revealed the source of blood loss and explained his rapid decompensation. He was successfully treated with arterial coiling and embolization. Thus, we herein emphasize the importance of prompt recognition of hemorrhagic shock and of aggressive hemodynamic stabilization, as well as a focused diagnostic approach to this problem with specific treatment for splenic artery pseudoaneurysm. Finally, we recommend that multidisciplinary management should be the standard approach in all patients with splenic artery pseudoaneurysm.

    Splenic artery aneurysm is the most frequent visceral artery aneurysm and rupture of the aneurysm is associated with a high mortality rate. It is important to discriminate between a true aneurysm and a pseudoaneurysm that may be caused by pancreatitis, iatrogenic and postoperative causes, trauma and peptic ulcer disease. Multidetector-row CT angiography (MDCTA) allows detailed visualization of the vascular anatomy and may allow identification of aneurysms and pseudoaneurysms that affect the splenic artery. The objective of this article is to provide a review of the general characteristics of splenic artery aneurysms and pseudoaneurysms and to describe the findings of MDCTA

    Full Text Available Introduction. Pancreatic pseudocyst presented as pseudoaneurysm of the splenic artery is a potential serious complication in patients with chronic pancreatitis. Case report. A 42-year-old male patient with a long-standing evolution of chronic pancreatitis and 8-year long evolution of pancreas pseudocyst was referred to the Military Medical Academy, Belgrade due to worsening of the general condition. At admission, the patient was cachectic, febrile, and had the increased values of amylases in urine and sedimentation (SE. After clinical and diagnostic examination: laboratory assessment, esophagogastroduodenoscopy (EGDS, ultrasonography (US, endoscopic ultrasonography (EUS, multislice computed scanner (MSCT angiography, pseudoaneurysm was found caused by the conversion of pseudocyst on the basis of chronic pancreatitis. The patient was operated on after founding pancreatic pseudocyst, which caused erosion of the splenic artery and their mutual communication. Postoperative course was duly preceded without complications with one year follow-up. Conclusion. Angiography is the most reliable and the safest method for diagnosing hemorrhagic pseudocysts when they clinically present as pseudoaneurysms. A potentially dangerous complication in the presented case was treated surgically with excellent postoperative results.

    Full Text Available A 64-year-old man presented to the hospital because of hematemesis; on admission, he had weakness and pale skin, tachycardia and hypotension. Laboratory tests revealed severe anemia (hemoglobin 7.8 g/dL; liver, renal and pancreatic function tests were normal. An upper digestive endoscopy revealed a gastric ulcer of the cardia, treated with metallic clips and adrenalin injection. The patient was treated with fluids and was transfused with three units of red blood cells. In the previous two months, due to the presence of bloating and diarrhea, associated with abdominal distension, a colon-computed tomography (CT revealed a large retroperitoneal hypodense mass, 53x37 mm in size, without contrast enhancement localized between the body and the tail of the pancreas and the stomach, near the splenic artery and without signs of infiltration. To better define the mass, endoscopic ultrasound and biopsy were performed; however histopathology of multiple biopsies was not diagnostic, because of the presence of necrotic tissue and inflammatory cells. Since hematemesis recurred, the patient underwent a second upper digestive endoscopic examination, but no source of bleeding was found. Then a new contrast enhanced CT was performed that showed a size reduction of the mass, the presence of blood in the stomach and a small pseudoaneurysm of the splenic artery. Because of these findings an angiograpghic study was carried out; angiography confirmed a splenic artery pseudoaneurysm that was successfully embolized with metal microcoils.

    Splenic artery aneurysm and pseudoaneurysm are rare pathologies. True aneurysms are usually asymptomatic. Aneurysm rupture occurring in 2–3% of cases results in bleeding into the lesser sack, peritoneal space or adjacent organs typically presenting as abdominal pain and hemodynamic instability. In contrast, pseudoaneurysms are nearly always symptomatic carrying a high risk of rupture of 37–47% and mortality rate of 90% if untreated. Therefore, prompt diagnosis and treatment are essential in the management of patients with splenic artery pseudoaneurysm. Typical causes include pancreatitis and trauma. Rarely, the rupture of a pseudoaneurysm presents as upper gastrointestinal (UGI) bleeding. Among causes, peptic ulcer is the casuistic one. This report describes a very rare case of recurrent UGI bleeding from a splenic artery pseudoaneurysm caused by a penetrating gastric ulcer. After negative results of endoscopy and ultrasound, the diagnosis was established in CT angiography. The successful treatment consisted of surgical ligation of the bleeding vessel and suture of the ulcer with preservation of the spleen and pancreas, which is rarely tried in such situations. The most important factor in identifying a ruptured splenic artery pseudoaneurysm as a source of GI bleeding is considering the diagnosis. UGI hemorrhage from splenic artery pseudoaneurysm can have a relapsing course providing false negative results of endoscopy and ultrasound if performed between episodes of active bleeding. In such cases, immediate CT angiography is useful in establishing diagnosis and in application of proper therapy before possible recurrence

    Full Text Available Splenic artery pseudoaneurysms (PSA are rare entities and far less common than true aneurysms of the splenic artery. The most common etiology is pancreatitis, recurrent either in the setting of chronic pancreatitis or as an episode of acute pancreatitis. Less common causes include trauma, peptic ulcer disease, or iatrogenic causes. Almost all of the trauma-related case reports have been due to blunt trauma. We believe this to be the first reported case of a splenic artery PSA presenting with massive hematemesis at a significant time frame after penetrating trauma. Successful transcatheter treatment was performed and alternative techniques are also discussed.

    An arterial rupture resulting from stent-graft placement of a splenic artery pseudoaneurysm is a life-threatening complication and immediate endovascular or surgical treatment is indicated. We report a case of a stentgraft related splenic artery rupture treated solely with a prolonged balloon catheter tamponade, which resulted in preservation of vessel patency

    The delayed development of splenic artery pseudoaneurysm (SAP) can complicate the nonoperative management of splenic injuries. We sought to determine the utility of repeat imaging in diagnosing SAP in patients managed nonoperatively without angioembolization. We hypothesized that a significant rate of SAPs would be found in this population on repeat imaging. Patients undergoing nonoperative splenic injury management from January 2011 to June 2015 were queried from the trauma registry. Rates of repeat imaging, angioembolization, readmission, and SAP development were analyzed. Further, subanalyses investigating the incidence of SAP in patients managed nonoperatively without angioembolization were conducted. A total of 133 patients met inclusion criteria. Repeat imaging rate was 40 per cent, angioembolization rate was 26 per cent, and readmission rate was 6 per cent. Within the study population, nine SAPs were found (8/9 in patients with splenic injury grade ≥III). Of these nine SAPs, three (33%) were identified on initial scans and embolized, whereas six (67%) were found on repeat imaging in patients not initially receiving angioembolization. Splenic injuries are typically managed nonoperatively without serious complications. Our results suggest patients with splenic injuries grade ≥III managed nonoperatively without angioembolization should have repeat imaging within 48 hours to rule out the possibility of SAP.

  12. Double splenic artery pseudoaneurysm with pancreatic pseudocyst: A therapeutic stalemate

    Full Text Available Pseudoaneurysm is a rare but a potentially fatal complication associated with chronic pancreatitis. The presence of concomitant aneurysms has been reported rarely and poses a therapeutic challenge owing to the technical difficulty in accessing the distal aneurysm by endovascular means and increased chances of rupture and bleeding. Here, we report an unusual presentation of simultaneous occurrence of two pseudoaneurysms on the splenic artery (SA. A 50-year-old male, a known case of chronic pancreatitis, presented with acute abdomen and a pulsating epigastric lump. A diagnosis of double pseudoaneurysm of SA with a concomitant pseudocyst was made based on contrast-enhanced computed tomography and was confirmed by angiography. The endovascular coil embolization by the standard sandwich-technique was expected to increase the risk of expansion and rupture of the distal pseudoaneurysm, and hence was managed by adapting a modified endovascular technique, following which patient made uneventful recovery. Double pseudoaneurysm of SA associated with chronic pancreatitis is an unusual presentation. Conventional endovascular treatment used for single aneurysm may not be feasible in the presence of two aneurysms, and it needs to be tailored according to the physical site, size, and the anatomy of the vasculature associated with the aneurysms.

    Conservative therapy for splenic injuries is widely advocated. The advantages of conservative therapy for splenic injuries include the preservation of splenic immune function, prevention of overwhelming post-splenectomy sepsis, and avoidance of laparotomy and its associated early and late complications. Pseudoaneurysms of the splenic artery branch are encountered because of the prevalence of conservative management and widespread use of imaging techniques in the follow-up of these cases. We report two cases of post-traumatic splenic pseudoaneurysm in children which thrombosed spontaneously, one during the diagnostic angiogram examination and another on follow-up studies. (orig.)

  14. Spontaneous Superior Mesenteric Artery Branch Pseudoaneurysm: A Rare Case Report

    Full Text Available : Background: Visceral arterial pseudoaneurysms (VAPAs are rare vascular entities with serious consequences. Traditionally, they are associated with trauma, infection, and inflammatory disease, or they can arise as a post-operative complication. Report: An 87 year old man presented with abdominal pain and was found to have a spontaneous VAPA on a computed tomography angiogram. Serial imaging 4 months previously had demonstrated no aneurysm. Between scans, warfarin was changed to apixaban for aortic valve replacement, but he had no other changes to any other medications. He required urgent endovascular coiling of the pseudoaneurysm, with satisfactory recovery and outcome. Discussion: VAPAs are extremely rare, with splenic artery VAPAs the most commonly reported. Regardless, fewer than 250 cases of splenic artery pseudoaneurysm have been reported. Superior mesenteric artery (SMA pseudoaneurysms are the rarest type of VAPAs. Early identification and urgent treatment are warranted because of the associated high mortality risk, with a 50% risk of rupture in any given VAPA. Treatment options range from open operation to endoscopic and endovascular procedures. Apixaban has been proposed to contribute to pseudoaneurysm formation by slow and continuous bleeding that results in the formation of the pseudoaneurysm. Conclusions: Spontaneous VAPAs are extremely rare and this is the first time a VAPA has been associated with the novel oral anticoagulant “apixaban”. Urgent management of any VAPAs is important because of the high risk of rupture and potential life threatening haemorrhage.

    Acute or chronic blood loss from pseudoaneurysms of the splanchnic artery in chronic pancreatitis poses diagnostic and management challenges. Arteriographic examination offers both diagnostic and therapeutic options, with success rates of 76%-100% for both modalities. In cases of failure of embolization, repeat embolization is also an option. Surgical intervention is advocated for rebleeding and failure of embolization. Evidence-based guidelines regarding the optimal treatment modality for this condition are lacking. There has been a reported case of dislodgement of coil into the stomach through a gastropseudocystic fistula. We report the case of a migrating steel-wire coil through the gastrointestinal tract and splenic artery pseudoaneurysm. We highlight the potential complications of pseudoaneurysm and other available therapeutic management options

    Splenic artery aneurysm is the third most common abdominal aneurysm. Most often it is due to pancreatitis. There were only 19 cases of aneurysms larger than 5 cm in diameter described in the literature. Management of splenic artery aneurysms depends on the size and symptoms. Invasive treatment modalities involve open procedures and interventional radiology methods (endovascular). A 44-years-old male with chronic pancreatitis, in a gradually worsening general condition due to a large splenic artery aneurysm, was subjected to the procedure. Blood flow through the aneurysm was cut-off by implanting a covered stent between celiac trunk and common hepatic artery. Patient’s general condition rapidly improved, allowing discharge home in good state soon after the procedure. Percutaneous embolization appears to be the best method of treatment of large splenic artery aneurysms. Complications of such treatment are significantly less dangerous than those associated with surgery

    Objective: To evaluate the clinical value of multiple detector computed tomography (MDCT) in the diagnosis and planning the treatment of splenic aneurysms. Methods: Eight cases with splenic artery aneurysms (SAA) were retrospectively reviewed. Sixty four-slice spiral CT scans were performed. Intravenous contrast material was injected at 4 ml/s, and arterial and venous phase images were obtained. Subsequently, arterial phase images were analyzed and made for CT angiography. The diagnosis was made by using axial and reconstructive images. All of the patients were also performed Doppler color echocardiography. Results: All patients showed splenic artery and splenic artery aneurysms clearly with CT arterial phase images. Among them, six patients had splenic artery aneurysms, one had giant splenic artery aneurysms (GSAA) and one had splenic artery pseudoaneurysms. Ultrasound examination only diagnosed six of them. Conclusion: MDCT is a noninvasive and valuable method in diagnosis of splenic artery aneurysms and has high value in determination of treatment plan

    2010-07-01

    Full Text Available “Haemosuccus pancreaticus” is an unusual cause of severe upper gastrointestinal bleeding and results from rupture of splenic artery aneurysm into the pancreatic duct. More commonly, it is a pseudoaneurysm of the splenic artery which develops as sequelae of pancreatitis. However, true aneurysm of the splenic artery without pancreatitis has rarely been incriminated as the etiologic factor of this condition. Owing to the paucity of cases and limited knowledge about the disease, diagnosis as well as treatment become challenging. Here we describe a 60-year-old male presenting with severe recurrent upper gastrointestinal bleeding and abdominal pain, which, after considerable delay, was diagnosed to be due to splenic artery aneurysm. Following an unsuccessful endovascular embolisation, the patient was cured by distal pancreatectomy and ligation of aneurysm.

    Purpose: To assess the value of contrast-enhanced sonography (CES) for the detection of delayed post-traumatic splenic pseudo-aneurysms, usually considered an indication for angiographic embolization. Methods: Sixty-three consecutive hemodynamically stable trauma patients in whom admission CT displayed a splenic injury of grade II or higher (AAST classification), without evidence of vascular involvement, were included in the study. CES of the spleen using a second generation contrast agent was systematically performed within 48–72 h after admission, for the detection of a pooling of contrast media suggestive of pseudoaneurysm. Within 6 h after contrast-enhanced sonography, all patients underwent an abdominal CT for control purposes. CES results were compared to CT findings, which were considered the reference standard. This study received approval from the institutional ethical board. Results: CES showed a blush of contrast consistent with a pseudoaneurysm in 6 of the 63 patients. All were confirmed at subsequent control CT. Pooling of contrast was found at CT in 2 patients in whom contrast-enhanced sonography was negative. There was no false positive CES examination for the suspicion of pseudoaneurysms. When compared to CT, the sensitivity, specificity, positive and negative predictive values of CES to suggest a pseudoaneurysms, were 75% (6/8), 100% (55/55), 100% (6/6), and 96% (55/57), respectively. Conclusion: Our data suggest that CES may be useful for the screening of delayed traumatic splenic pseudoaneurysms: if a negative CES does not absolutely rule out a pseudoaneurysm, a positive CES warrants an angiography, without need of control CT.

    Pseudoaneurysmal epistaxis is a rare but emergent condition. We report a case of traumatic anterior cerebral artery pseudoaneurysmal epistaxis and review the published literature. A 49-year-old man sustained severe head trauma. He was diagnosed with multiple skull bone fractures, left subdural hematoma, subarachnoid hemorrhage, pneumocephalus, and right frontal hematoma. Subdural hematoma evacuation was done at a local hospital. In the following months, he experienced repeated epistaxis that required nasal packing to stop the bleeding. Digital subtraction angiography showed an anterior cerebral artery pseudoaneurysm protruding into the posterior ethmoid sinus. Embolization of the aneurysm was performed with microcoils, and the parent artery was occluded by thrombosis. The patient presented 1 month later with another epistaxis episode. Digital subtraction angiography showed recanalization of the parent artery and recurrence of the aneurysm. The parent artery was occluded for the second time with coils and Onyx embolic agent. Pseudoaneurysmal epistaxis is rare, and this is the first report of an anterior cerebral artery pseudoaneurysm that manifested with epistaxis. Endovascular intervention has become the first choice of treatment for this disease. The high recurrence rate is the main disadvantage of endovascular intervention. Aneurysm trapping with bypass surgery is another treatment option. Copyright © 2016 Elsevier Inc. All rights reserved.

    Occipital artery pseudoaneurysms are extremely rare pathologies that manifest after traumatic injury; only 11 cases have been reported in the literature. Because of their low incidence and vague symptoms, the initial diagnosis can be difficult. However, for correctly diagnosed occipital artery pseudoaneurysms, many successful treatment modalities exist. We review the pathology of occipital pseudoaneurysms, elucidate the reasons for their rarity, discuss effective diagnostic measures, and discuss the currently available treatment options. We also present a case of a 16-year-old boy who sustained blunt force trauma in May 2014 and presented 6 months later with a painful, pulsatile mass in the occipital region. The patient underwent surgical resection to alleviate the pain and the potential risk of hemorrhage. He experienced complete resolution of pain and associated symptoms. Our case highlights the fact that occipital swelling, a significant initial sign of pseudoaneurysm development, can be delayed. Therefore, occipital artery pseudoaneurysms cannot be ruled out of the differential diagnosis based on time course alone. Surgical resection is a quick and effective method for relief of severe pain resulting from occipital artery pseudoaneurysms. Although they are rare entities, occipital artery pseudoaneurysms must be considered in the differential diagnosis of cases of pulsatile mass lesions in the posterior scalp.

    Objective: To evaluate the therapeutic roles of transcatheter embolization in patients with pseudoaneurysms complicating acute severe pancreatitis. Methods: Seven patients who suffered from pseudoaneurysms complicating acute severe pancreatitis received abdominal angiography and were treated with transcatheter embolization. The angiographic findings, complications related to the procedure and post- embolization, and rebleeding were observed. Results: The pseudoaneurysms developed at the splenic artery (n=5), right gastroepiploic artery (n=1), and left gastric artery (n=1), respectively. Findings of active bleeding were observed in 3 patients. Six of them were embolized with coils, and the bleedings were stopped immediately. Rebleeding occurred 14-60 days after the embolization in 3 patients, and in one of them, another pseudo aneurysm was observed in repeated angiography and was successfully treated by repeated embolization. No causes of bleeding were found in repeated angiography in the other 2 patients, who died from severe hemorrhage. One pseudo aneurysm was embolized with gelfoam granule. The gastrointestinal bleeding was not controlled and the patient died 3 days later. Procedure related complications occurred in 2 patients. One was celiac trunk rupture during angiography, the other was intima dissecting in splenic artery. Severe post procedure complications occurred in none of the patients. Conclusion: Transcatheter embolization is safe and relatively effective in the management of pseudoaneurysms complicating acute severe pancreatitis. (authors)

    Full Text Available The aneurysmsatic changes of the infrapopliteal arteries are rarely seen. They are pseudoaneurysms rather than true aneursyms. The most important cause of them is trauma. There is not a standart treatment for infrapopliteal aneursyms. In this study, we have evaluated a case operated for anterior tibial artery pseudoaneurysm developed after penetrant trauma and diagnosed two weeks later. [Cukurova Med J 2012; 37(3.000: 172-175

    Carlos Eli Piccinato

    Full Text Available BACKGROUND: Several vascular complications are known to occur in association with the acquired immunodeficiency syndrome (AIDS and recent publications have called attention to the development of pseudoaneurysms of large arteries in patients with AIDS. CASE REPORT: We report on 2 patients with AIDS aged 23 and 31 years with pseudoaneurysms of the abdominal aorta and common iliac arteries. After clinical and radiological evaluation by arteriography and computed tomography, the patients were submitted to aneurysmectomy, with the placement of a patch of dacron in the first case and the interposition of a right aorto-iliac and left femoral prosthesis in the second. The second patient developed new aneurysms of the right subclavian and left popliteal arteries 2 months after surgery. Proximal ligation of the right subclavian artery was performed to treat the first aneurysm and resection and interposition of a reversed saphenous vein was carried out to treat the pseudoaneurysm of the popliteal artery. Histopathological examination of the popliteal artery revealed necrotizing arteritis.

    In bleeding of oesophageal varices with resistance to common treatment embolisation of the splenic artery causes depression of the portal hypertension by forty per cent. Thrombosis of the splenic or portal vein as in splenectomies are not to be expected. The splenic vein remains open for later spleno-renal anastomosis. By occlusion of the splenic artery we were successful in stopping oesophageal bleeding. In a patient with dominant hypersplenism in portal hypertension the severity of the syndrome decreased after embolisation of the splenic artery. Thrombocytes, leukocytes and gammaglobulin increased.

    Gastroduodenal artery pseudoaneurysm is a relatively rare and potentionally life-threatening complication of chronic pancreatitis, which is thought to occur because of autodigestion of arterial walls by pancreatic enzymes. Embolotherapy should probably be the first method of treatment, since surgical treatment carries a high risk of mortality and morbidity. We report the case of 30-year-old male with gastroduodenal artery pseudoaneurysm caused by chronic pancreatitis which was successfully treated by transcatheter embolization using Gianturco spring coils.

    The purpose of this retrospective study was to evaluate the role of transcatheter arterial embolization in the management of severe postpartum haemorrhage due to a ruptured pseudoaneurysm and to analyse the clinical symptoms that may suggest a pseudoaneurysm as a cause of postpartum haemorrhage. A retrospective search of our database disclosed seven women with severe postpartum haemorrhage in whom angiography revealed the presence of a uterine or vaginal artery pseudoaneurysm and who were treated using transcatheter arterial embolization. Clinical files were reviewed for possible clinical findings that could suggest pseudoaneurysm as a cause of bleeding. Angiography revealed extravasation of contrast material in five out of seven patients. Transcatheter arterial embolization allowed to control the bleeding in all patients and subsequently achieve vaginal suture in four patients with vaginal laceration. No complications related to transcatheter arterial embolization were noted. Only two patients had uterine atony, and inefficiency of sulprostone was observed in all patients. Transcatheter arterial embolization is an effective and secure technique for the treatment of severe postpartum haemorrhage due to uterine or vaginal artery pseudoaneurysm. Ineffectiveness of suprostone and absence of uterine atony should raise the possibility of a ruptured pseudoaneurysm. (orig.)

    Traumatic urethral catheterization may result in a number of serious complications. A rare occurrence is the development of a urethral pseudoaneurysm. We report the case of a 13-year-old male who required placement of a Foley catheter for an orthopedic surgical procedure. The Foley was misplaced in the bulbourethra, resulting in the development of a bulbar artery pseudoaneurysm. Profuse bleeding via the urethra was noted after removal of the catheter, and the patient experienced severe intermittent hematuria during the postoperative period. Cystoscopy revealed a pulsatile mass within the bulbourethra. Angiography confirmed a bulbar artery pseudoaneurysm, which was successfully embolized with resolution of bleeding.

    Full Text Available Abstract The renal artery pseudoaneurysm embody a rare vascular complication coming of percutaneous procedures, renal biopsy, nephrectomy, penetrating traumas and more rarely blunt traumas. The clinical can be vary according the patient, the haematuria is the symptom more commom. Is necessary a high level of clinical suspicion for your diagnosis, this can be elucidated by through complementary exams as the eco-color Doppler and the computed tomography scan (CT. This report is a case of a patient submitted a right percutaneous renal biopsy and that, after the procedure started with macroscopic haematuria, urinary tenesmus and hypogastric pain. The diagnosis of pseudoaneurysm was given after one week of evolution when the patient was hospitalized because gross haematuria, tachycardia, hypotension and hypochondrium pain. In the angiotomography revealed a focal dilation of the accessory right renal inferior polar artery, dilation of renal pelvis and all the ureteral course with presence hyperdenso material (clots inside the middle third of the ureter. The treatment for the majority of this cases are conservative, through arterial embolization, indicated for thouse of smaller dimensions in patients who are hemodynamically stable. However, it was decided by clinical treatment with aminocaproic acid 1 g, according to previous studies for therapy of haematuria. The patient received discharge without evidence of macroscopic haematuria and with normal renal ultrasound, following ambulatory care.

    Gluteal artery aneurysms are rare and often secondary to pelvic fractures, blunt or penetrating trauma. We describe a case of a superior gluteal artery pseudoaneurysm that presented as back pain with numbness and weakness of the lower extremities. Diagnosis was confirmed by color Doppler sonography and angiography. A proximal and distal control was obtained over the aneurysm neck via coil embolization with excellent hemostasis within the pseudoaneurysm and maintenance of perfusion to the left pelvis. (orig.)

    Delayed presentation of a brachial artery pseudoaneurysm following penetrating trauma is infrequently reported. We report the case of a 23-year-old male who presented three months following a penetrating trauma to his antecubital fossa with a sudden exacerbation of swelling and tenderness of his elbow. Doppler ultrasound and computed tomography arteriography confirmed the presence of a large pseudoaneurysm. Surgical reconstruction was performed using the long saphenous vein as an interposition vein graft, restoring normal arterial circulation.

    Purpose: To review some aspects of the problem of splenic artery steal syndrome as cause of ischemia in transplanted livers and treatment by selective splenic artery occlusion. Materials and Methods: Eleven liver transplant patients from a group of 350 patients, nine men and two women,ranging in age from 40 years to 61 years (mean 52 years), presented with biochemical evidences of liver ischemia and failure, ranging from one to 60 days following orthotopic liver transplantation. Diagnosis of splenic artery steal syndrome was suspected by elevated enzymes, Doppler ultrasound and confirmed by celiac angiogram. Patients with confirmed hepatic artery thrombosis before angiography were excluded from the study. Embolization with Gianturco coils was performed. Results: All patients were treated by splenic artery embolization with Gianturco coils. The 11 patients improved clinically within 24 hours of the procedure with significant change in the biochemical and clinical parameters. Followup ranged from one month to two years. One of the 11 patient initially improved, but developed hepatic artery thrombosis within 24 hours of the embolic treatment,requiring surgical repair. Conclusion: Splenicartery steal syndrome following liver transplantation surgery can be diagnosed by celiac angiography, and effectively treated by splenic artery embolization with coils. Embolization is one of the treatments available, it is minimally invasive, and leads to immediate clinical improvement. Hepatic artery thrombosis is a possible complication of the procedure

    We report a case of a 64-year-old man who developed a painful pulsatile mass in the distal forearm after a bicycle fall with fracture of the wrist. Ultrasonography confirmed a 2.5-cm large pseudoaneurysm of the radial artery. The patient underwent surgical exploration. The pseudoaneurysm was resected and the defect in the arterial wall was reconstructed with an autologous saphenous vein patch. We suggest that the double arterial supply of the hand should be preserved whenever possible.

  4. Thrombosed Popliteal Artery Pseudoaneurysm as Herald of Tibial Osteochondroma

    Directory of Open Access Journals (Sweden)

    A.M. Ruales Romero

    Full Text Available Background: Osteochondroma is the most common non-malignant tumour of bone, accounting for approximately one third of benign lesions in the skeleton. They often develop around the knee in the distal femur and in the proximal tibia and fibula. They present as a painless slow growing mass during adolescence and have been reported to cause damage to adjacent structures such as blood vessels; arterial damage is more common than venous injury and is usually a result of compression, stretching, and rubbing of the arterial wall. Such lesions include stenosis, thrombosis, and pseudoaneurysm formation possibly causing lower limb claudication or acute limb ischemia. Methods: An 18 year old male patient with a 4 week history of pain, hematoma, and oedema of the left calf without previous trauma is reported. A computed tomography scan (CT revealed a large popliteal artery pseudoaneurysm and its close relationship to a protrusion of the proximal tibia. Results: The popliteal artery was repaired by an external saphenous patch and the exostosis was removed. The patient had palpable popliteal and distal pulses after surgery and during the first year follow-up. Conclusions: Tibial osteochondroma should be considered in the differential diagnosis in young patients, among the potential causes of pseudoaneurysm of the femoral or popliteal artery. Surgical repair should be performed to restore normal blood flow with resection of the exostosis to prevent recurrence. Keywords: Popliteal artery, Pseudoaneurysm, Tibial exostosis, Osteochondroma

    To assess the feasibility and safety of the endovascular treatment of ruptured hepatic artery pseudoaneurysms after pylorus preserving pancreaticoduodenectomy (PPPD). Thirteen patients with hepatic artery pseudoaneurysm after PPPD were enrolled. Various endovascular techniques were used depending on the sites and morphologies of the pseudoaneurysms. Five cases were treated by coil embolization, five with stent-graft, one by thrombin injection and coil embolization, one with stent-graft and coil embolization, and one with N-butyl cyanoacrylate (NBCA) injection. Computed tomography scans and liver function test were performed after the procedures. Pseudoaneurysm exclusion and bleeding cessation was achieved in all patients. In four patients that underwent coil or NBCA embolization of the hepatic artery, aspartate transaminase (AST) and alanine transaminase (ALT) were markedly elevated. Two of these four patients with narrowing of the portal vein due to surrounding hematoma died of hepatic infarction or hepatic abscess. In other nine patients, AST and ALT were unchanged. In the 11 surviving patients, normal hepatic function and complete pseudoaneurysm disappearance were achieved during follow-up. Endovascular treatment of ruptured hepatic artery pseudoaneurysms can be considered as a feasible and safe method. However, complete occlusion of the hepatic artery with coils should be avoided in patients with inadequate portal flow.

    PurposeHepatic artery pseudoaneurysms are a rare but potentially life-threatening complication of major pancreaticobiliary surgery. We evaluated the safety and efficacy of endovascular stentgraft implantation for the management of such vascular lesions.Materials and MethodsBetween May 2013 and October 2015, ten patients with postoperative hepatic artery pseudoaneurysm, of which eight presented with active hemorrhage, were treated with endovascular stentgraft implantation. All patients had undergone major pancreatic or hepatic surgery before (pylorus-preserving pancreaticoduodenectomy, pancreatectomy, hemihepatectomy, extended hemihepatectomy). The pseudoaneurysms were diagnosed 13–202 days after surgery and were associated with postsurgical complications (e.g., leakage of pancreaticojejunal anastomosis).ResultsIn 9/10 patients, the pseudoaneurysm was completely excluded via stentgraft implantation. In 1/10 patient, the pseudoaneurysm ruptured during the procedure and was successfully treated by immediate open surgery. In 1/10 patient, a second intervention was performed after 6 days because of rebleeding; this was successfully treated by implantation of a second overlapping stentgraft. Mean follow-up time is 51 days. None of the patients died due to stentgraft- or aneurysm-related complications. Further episodes of hemorrhage were not observed. In one patient, clinically asymptomatic complete occlusion of the stentgraft was discovered at follow-up imaging.ConclusionStentgraft implantation is a safe and effective technique to treat hepatic artery pseudoaneurysms related to major pancreatic or hepatic surgery, especially in the setting of acute hemorrhage.

    Ruptured mycotic pulmonary pseudoaneurysm is a lethal complication. Emergent surgical repair is usually recommended, but still associated with a high mortality rate. We present a patient in whom mycotic pulmonary pseudoaneurysm was a complication after surgical lobectomy 2 weeks earlier. This patient had suffered from repeated massive hemoptysis. After emergent surgical repair of the ruptured pulmonary artery stump, another episode of massive hemorrhage occurred. The pulmonary arteriogram revealed a segmental stenosis and a large, wide-necked, lobulated pseudoaneurysm at the left proximal pulmonary artery. We deployed a balloon-expandable stent-graft (48 mm in length mounted on a 12 mm x 40 mm angioplasty balloon) across the stenotic segment and the neck of the pulmonary pseudoaneurysm. Hemostasis was achieved immediately and, under a 4-week antibiotic treatment, patient was transferred to a local hospital for medical care. This case report demonstrates the benefit of minimally invasive endovascular therapy in a critically ill patient. A literature review of the etiology and management of mycotic pulmonary pseudoaneurysm is included

    Full Text Available To present the various techniques used in the management of pancreatitis-related pseudoaneurysms of visceral vessels.The retrospective clinical study was carried out at the Department of Diagnostic and Interventional Radiology at Poznan University of Medical Sciences from 2011 to 2016. The fifteen patients included in the study were diagnosed with pseudoaneurysms of visceral arteries, as a complication of chronic pancreatitis. The diagnosis was made using contrast-enhanced computed tomography, followed by angiography. On admission, all patients were symptomatic, with varying degrees of abdominal pain. One patient was haemodynamically unstable. Treatments with endovascular techniques were analysed, along with their efficacy and outcomes. Coil embolisation was performed in 5 patients. Stent graft was used in 1 patient. Liquid embolic agents were used in 7 cases, of which 5 patients were treated with thrombin injection and 2 with Squid. A combination of techniques was used in 2 patients.The most common artery affected by pseudoaneurysm formation was the splenic artery (7/15; 46.7%, and the size of the pseudoaneurysms ranged from 27 mm to 85 mm. Primary technical success was achieved in 14 out of 15 patients (93.3%. One patient required reintervention. Two patients required splenectomy after embolisation due to splenic ischemia. No recanalisation was present at the follow-up computed tomography performed after 1 to 3 weeks, and no mortality was observed within 30 days.Vascular complications of pancreatitis require accurate diagnosis and immediate treatment. Endovascular intervention is highly effective and is the preferred treatment option. The technique used is determined based on vascular anatomy and the patient's haemodynamic status.

    Hepatic artery pseudoaneurysm is an infrequently encountered entity that is usually seen secondary to trauma or surgical procedures. The clinical presentation is often due to complications such as massive intrahepatic or intraperitoneal bleeding as a result of rupture of the pseudoaneurysm into the biliary tree or peritoneal cavity, respectively. Hepatic artery pseudoaneurysm, associated with a liver abscess, has very rarely been described in the literature. We present the imaging features of a case of liver abscess associated with a hepatic artery pseudoaneurysm and complicated by rupture and formation of an arteriovenous fistula. The case was successfully managed by percutaneous endovascular embolization. The association between a hepatic artery pseudoaneurysm and a liver abscess must not be overlooked, bearing in mind the potentially fatal associated complications which can be averted or treated by timely intervention

    Hepatic artery pseudoaneurysm is an infrequently encountered entity that is usually seen secondary to trauma or surgical procedures. The clinical presentation is often due to complications such as massive intrahepatic or intraperitoneal bleeding as a result of rupture of the pseudoaneurysm into the biliary tree or peritoneal cavity, respectively. Hepatic artery pseudoaneurysm, associated with a liver abscess, has very rarely been described in the literature. We present the imaging features of a case of liver abscess associated with a hepatic artery pseudoaneurysm and complicated by rupture and formation of an arteriovenous fistula. The case was successfully managed by percutaneous endovascular embolization. The association between a hepatic artery pseudoaneurysm and a liver abscess must not be overlooked, bearing in mind the potentially fatal associated complications which can be averted or treated by timely intervention.

    Full Text Available Carotid artery pseudoaneurysm is a rare condition, particularly in the paediatric population. Only about 30 cases of carotid artery aneurysms in infants have been published until now. This paper reports the case of a giant pseudoaneurysm of the left common carotid artery due to swallowed fish bone by an 8-year-old boy. This pseudoaneurysm was 5.5 cm transverse-diameter and resulted in severe respiratory distress. It was treated by resection and end-to-end anastomosis with satisfactory outcome after one-year follow-up. To the best of our knowledge, this is the largest carotid artery pseudoaneurysm ever described in children.

    Full Text Available Abstract Background A bleeding pseudoaneurysm in patients with chronic pancreatitis is a rare and potentially lethal complication. Optimal treatment of bleeding peripancreatic pseudoaneurysm remains controversial. This study reports on experience at Chang Gung Memorial Hospital (CGMH in managing of bleeding pseudoaneurysms associated with chronic pancreatitis. Methods The medical records of 9 patients (8 males and 1 female; age range, 28 – 71 years; median, 36 years with bleeding pseudoaneurysms associated with chronic pancreatitis treated at CGMH between Aug. 1992 and Sep. 2004 were retrospectively reviewed. Alcohol abuse (n = 7;78% was the predominant predisposing factor. Diagnoses of bleeding pseudoaneurysms were based on angiographic (7/7, computed tomographic (4/7, ultrasound (2/5, and surgical (2/2 findings. Whether surgery or angiographic embolization was performed was primarily based on patient clinical condition. Median follow-up was 38 months (range, 4 – 87 months. Results Abdominal computed tomography revealed bleeding pseudoaneurysms in 4 of 7 patients (57%. Angiography determined correct diagnosis in 7 patients (7/7, 100%. The splenic artery was involved in 5 cases, the pancreaticoduodenal artery in 2, the gastroduodenal artery in 1, and the middle colic artery in 1. Initial treatment was emergency (n = 4 or elective (n = 3 surgery in 7 patients and arterial embolization in 2. Rebleeding was detected after initial treatment in 3 patients. Overall, 5 arterial embolizations and 9 surgical interventions were performed; the respective rates of success of these treatments were 20% (1/5 and 89% (8/9. Five patients developed pseudocysts before treatment (n = 3 or following intervention (n = 2. Pseudocyst formation was identified in 2 of the 3 rebleeding patients. Five patients underwent surgical treatment for associated pseudocysts and bleeding did not recur. One patient died from angiography-related complications. Overall mortality

    The purpose of this study was to compare the efficacy of gelatin sponge with that of coils for splenic artery embolization in the treatment of blunt splenic injury. A single-center retrospective review was performed with the records of 63 patients (45 men, 18 women; mean age, 45.5 years; range, 16-84 years) with blunt splenic injury treated at a tertiary care trauma center by splenic artery embolization with gelatin sponge (n = 30 patients) or metallic coils (n = 33 patients) between 2005 and 2014. The two groups had comparable median American Association for the Surgery of Trauma grades of IV and comparable angiographic appearances regarding active extravasation and pseudoaneurysm formation at preembolization splenic arteriography (p = 0.32). Clinical outcomes and procedure-related outcomes were evaluated. The success rates were similar in the two groups: splenic artery embolization failed in 6.6% (2/30) of patients in the gelatin sponge group and 12.1% (4/33) in the coil embolization group (p = 0.45; 95% CI, -30.1% to 19.2%). Major complications occurred in six patients (20.0%) in the gelatin sponge group and in six patients (18.1%) in the coil group (p = 0.85; 95% CI, -23.0% to 26.6%). Minor complications occurred in three patients (10.0%) in the gelatin sponge group and seven patients (21.2%) in the coil group (p = 0.21; 95% CI, -35.4% to 14.0%). Procedure time was significantly shorter in the gelatin sponge group (median, 32 minutes; interquartile range, 18-48 minutes) than in the coil group (median, 53 minutes; interquartile range, 30-76 minutes) (p = 0.01). Splenic artery embolization with gelatin sponge appears to be as effective and as safe as coil embolization and can be completed in a shorter time.

    Objective: This study was designed to determine the incidence of arterial pseudoaneurysm in patients presenting with postpartum hemorrhage (PPH), to analyze the angiographic characteristics of pseudoaneurysms that cause PPH, and to evaluate the effectiveness of pelvic arterial embolization for the treatment of this condition.Study designEighteen women with pelvic arterial pseudoaneurysm were retrieved from a series of 588 consecutive patients with PPH treated by arterial embolization. Clinical files, angiographic examinations, and procedure details were reviewed. Results: The incidence of pseudoaneurysm was 3.06 % (18/588; 95 % confidence interval (CI): 1.82-4.8 %). A total of 20 pseudoaneurysms were found; 15/20 (75 %) were located on the uterine arteries. Angiography revealed extravasation of contrast material from pseudoaneurysm indicating rupture in 9 of 18 (50 %) patients. Arterial embolization was performed using gelatin sponge alone in 12 of 18 (67 %) patients or in association with metallic coils in 5 of 18 (28 %) patients or n-butyl-2-cyanoacrylate in 1 of 18 (6 %) patients. Arterial embolization allowed controlling the bleeding in all patients after one or two embolization sessions in 17 of 18 (94 %) and 1 of 18 patients (6 %) respectively, without complications, obviating the need for further surgery. Conclusions: Pseudoaneurysm is rarely associated with PPH. Arterial embolization is an effective and safe procedure for the treatment of PPH due to uterine or vaginal artery pseudoaneurysm. Our results suggest that gelatin sponge is effective for the treatment of ruptured pseudoaneurysms, although we agree that our series does not contain sufficient material to allow drawing definitive conclusions with respect to the most effective embolic material.

    To evaluate the significance of transcatheter arterial embolization(TAE) of pseudoaneurysm complicating pancreatitis. This study was based on a retrospective analysis of eight cases, in which TAE for control of pseudoaneurysm complicating pancreatitis was attempted. All patients were males, and were aged between 35 and 65(mean, 47) years. Seven had a history of episodes of chronic pancreatitis and one case was the result of acute pancreatitis. All patients underwent diagnostic angiography and superselective embolization. Arteries in which pseudoaneurysm had occurred were the gastroduodenal (n=3D5), inferior pancreaticoduodenal (n=3D1), superior mesenteric artery root (n=3D1), and the celiac axis (n=3D1). Six cases were treated successfully without complications, but in two, embolization failed due to a wide aneurysmal neck arising from the superior mesenteric artery root and celiac axis. In four successful cases, pseudoaneurysms were completely resolved within three to six months of embolization. One of the other two remained as a pseudocyst, while in the other, also a pseudocyst, surgery was performed. Because TAE in patients with pseudoaneurysm complicating pancreatitis has a high success rate, and also leads to absolute resorption of a pseudocyst, TAE is the preferred pre-surgical treatment mode.=20

    Visceral artery pseudoaneurysms occur mostly as a result of inflammation and trauma. Owing to high risk of rupture, they require early treatment to prevent lethal complications. Knowledge of the various approaches of embolization of pseudoaneurysms and different embolic materials used in the management of visceral artery pseudoaneurysms is essential for successful and safe embolization. We review and illustrate the endovascular, percutaneous and endoscopic ultrasound techniques used in the treatment of visceral artery pseudoaneurysm and briefly discuss the embolic materials and their benefits and risks.

    Traumatic intracranial pseudoaneurysm is a rare complication of blunt trauma. It is even more rare when it presents as epistaxis. Massive epistaxis of a ruptured intracranial internal carotid artery pseudoaneurysm is a major cause of mortality, which requires emergency intervention. We report a case of traumatic intracranial internal carotid artery pseudoaneurysm secondary to skull base fracture, which presented with delayed onset of epistaxis. This was successfully treated by primary endovascular coil embolization. We discuss endovascular treatment options and review the literature. PMID:26818170

    The common femoral artery is commonly used as arterial access for a wide range of radiological and cardiological procedures. Pseudoaneurysm formation is the most common arterial complication of femoral artery catheterization, and is diagnosed using colour Doppler ultrasound. Ultrasound-guided thrombin injection has replaced ultrasound-guided compression as the first-line treatment. The practicalities of thrombin injection (technique and types of thrombin available) and other treatment options are discussed. Awareness of pseudoaneurysm formation and the treatment options allows prompt diagnosis and successful treatment.

    Objective: To determine the methods and results of treating traumatic pseudoaneurysms in siphon segment of internal carotid artery (ICA)by interventional therapy. Methods: Twelve cases of traumatic pseudoaneurysms in siphon segment of internal carotid artery were treated. The collateral circulation of Willis circle was observed after DSA. Different methods of treatment were applied according to the collateral circulation of Willis circle. Ten cases were treated by occlusion of ICA completely, 1 case was embolized by guglielmi detachable coil (GDC) only. Results: Nine of 12 treated by occlusion of ICA were cured. In the 3 cases who had poor collateral of Willis circle, one was cured by GDC embolization alone; one died 48 hours later after ICA occlusion though his consciousness and the activity of extremities were normal during the temporary balloon test occlusion (BTO) of ICA. One died during the training to improve the collateral of the Willis circle. Conclusion: ICA embolization is feasible for treatment of traumatic pseudoaneurysms in siphon segment of internal carotid artery after evaluating the collateral circulation of Willis circle.

    A case of transcatheter embolization of a celiac artery pseudoaneurysm in a 70-year-old man is reported. The pseudoaneurysm was considered to be the result of pancreatic anastomotic leakage and an intra-abdominal abscess following pancreaticoduodenectomy with irradiation of 66 Gy for pancreatic carcinoma. To avoid recanalization of the pseudoaneurysm due to retrograde blood flow, first all branches of the celiac artery were embolized with metallic coils, and then the celiac trunk was also occluded. Hepatic arterial flow was preserved by the right hepatic artery arising from the superior mesenteric artery. After the procedure, the patient had no noticeable complications associated with the embolization nor any recurrence of the pancreatic cancer, and he achieved a 2-year survival. (orig.)

    Full Text Available The authors present a case of a 39-year-old man with alcoholic chronic pancreatitis that was admitted in the emergency department after a car accident, complaining of abdominal pain and looking pale. The patient was hemodinamically unstable, requiring blood transfusions. He underwent computed tomography angiogram of the abdomen and pelvis, showing a pseudoaneurysm of the gastroduodenal artery and a hemoperitoneum. He was referred to our interventional radiology unit and submitted to endovascular treatment, consisting of ‘backdoor’ and ‘frontdoor’ embolization of the gastroduodenal artery and pseudoaneurysm neck with coils, with total exclusion in control angiography. With this case description we intend to highlight the rarity of the pseudoaneurysm rupture of the gastroduodenal artery and to emphasize the importance of an interventional radiology response that had a fundamental role in the endovascular treatment, in an emergency context.

    Pseudoaneurysm due to chronic pancreatitis is uncommon, but it can cause recurrent and massive hemorrhage. Because of high morbidity and mortality associated with the pseudoaneurysm, early detection and treatment is essential. Surgical ligation or resection of the aneurysm has a high mortality and therefore, transcatheter embolization is preferably carried out. We report a case in which gastroduodenal artery pseudoaneurysm caused by chronic pancreatitis was successfully treated by transcatheter embolization using Gelfoam and Gianturco spring coils

    We present a case of vertebral artery pseudoaneurysm after a posterior C1-C2 transarticular screw fixation procedure that was effectively treated with endovascular coil occlusion. Vertebral artery pseudoaneurysm complicating posterior C1-C2 transarticular fixation is extremely rare, with only one previous case having been reported previously. Endovascular occlusion is better achieved in the subacute phase of the pseudoaneurysm, when the wall of the pseudoaneurysm has matured and stabilized.

    A 26-year-old drug abuser who presented with sepsis was found to have a pseudoaneurysm in the left vertebral artery. This aneurysm was presumed to be post-traumatic, since the patient reported multiple attempts to inject drugs in the left jugular vein 15 days prior to admission. The pseudoaneurysm was treated effectively with stent-graft placement

    The purpose of this study was to evaluate clinical results and technical problems of transcatheter coil embolization for splenic artery aneurysm. Subjects were 16 patients (8 men, 8 women; age range, 40-80 years) who underwent transcatheter embolization for splenic artery aneurysm (14 true aneurysms, 2 false aneurysms) at one of our hospitals during the period January 1997 through July 2005. Two aneurysms (12.5%) were diagnosed at the time of rupture. Multiple splenic aneurysms were found in seven patients. Aneurysms were classified by site as proximal (or strictly ostial) (n = 3), middle (n = 3), or hilar (n = 10). The indication for transcatheter arterial embolization was a false or true aneurysm 20 mm in diameter. Embolic materials were fibered coils and interlocking detachable coils. Embolization was performed by the isolation technique, the packing technique, or both. Technically, all aneurysms were devascularized without severe complications. Embolized aneurysms were 6-40 mm in diameter (mean, 25 mm). Overall, the primary technical success rate was 88% (14 of 16 patients). In the remaining 2 patients (12.5%), partial recanalization occurred, and re-embolization was performed. The secondary technical success rate was 100%. Seven (44%) of the 16 study patients suffered partial splenic infarction. Intrasplenic branching originating from the aneurysm was observed in five patients. We conclude that transcatheter coil embolization should be the initial treatment of choice for splenic artery aneurysm

    Full Text Available Pseudoaneurysms of intercostal artery are very rare. All the published cases have been caused by trauma, either iatrogenic or otherwise. They can cause hemothorax, retroperitoneal hemorrhage or can present as pulsatile chest mass. Doppler ultrasound, contrast-enhanced CT and conventional angiogram can accurately diagnose this condition. All the reported cases have been treated by embolisation, stenting or surgery. We report an unusual case of intercostal artery pseudoaneurysm arising as a complication of corrosive poisoning presenting with hematemesis and treated by glue embolisation. The authors believe this to be the first case of intercostal artery pseudoaneurysm that is non-traumatic, complicating corrosive poisoning and presenting with hematemesis.

    Uterine artery pseudoaneurysm (UAP) normally presents genital bleeding in the puerperal period, and severe hydronephrosis rarely presents during pregnancy. We report a rare case of severe ureteral obstruction accompanied by uterine artery pseudoaneurysm in the early second trimester of pregnancy, which was successfully treated by surgical intervention. A 42-year-old nulligravid woman who had undergone myomectomy 3 years earlier was referred to our hospital for acute left abdominal pain at the 17th week of gestation. Ultrasonography showed severe left hydronephrosis and a 6-cm mass in the parauterine space. Color Doppler ultrasonography revealed a spinning turbulent flow pattern inside the mass lesion. Contrast-enhanced computed tomography revealed the left uterine artery feeding blood flow to the mass and left ureteral obstruction by the mass. These results indicated left hydronephrosis secondary to left uterine artery pseudoaneurysm. To resolve the problem, laparotomy was performed. As uterine artery isolation was impossible, ligation of the left internal iliac artery and releasing of the ureteral obstruction were carried out. The hydronephrosis and abdominal pain promptly resolved after the surgery. Thereafter, fetal development proceeded normally in the remaining months of the pregnancy. A healthy baby was delivered through cesarean section at 36 weeks gestational age. At the cesarean section, the left lower uterine segment where the UAP had been present was not visible because of the firm adhesion in around it. Uterine artery pseudoaneurysm can cause hydronephrosis in the early second trimester of pregnancy. Ligation of the unilateral internal iliac artery is a safe and effective intervention to block the blood flow to the uterine artery pseudoaneurysm during pregnancy, when uterine artery ligation seems not possible. In the pregnancy after previous surgical procedures to the uterus, uterine artery pseudoaneurysm should be considered in the differential

    A 71-year-old man affected by cardio- and cerebrovascular disease experienced an accidental fall and trauma to the fronto-temporal area of the head. A few weeks later a growing mass appeared on his scalp. A diagnosis of superficial temporal artery pseudoaneurysm was made following CT and color Doppler ultrasound. His clinical condition favoured a conservative approach by ultrasound-guided compression and subsequent surgical resection. A conservative approach should be considered the treatment of choice in critically ill patients affected by superficial temporal artery pseudoaneurysm

    A 65-year-old woman who had been diagnosed as having microscopic polyangiitis developed sudden abdominal pain and entered a state of shock. Abdominal CT showed massive hemoperitoneum, and emergent angiography revealed a ruptured splenic artery aneurysm. After direct catheterization attempts failed due to tortuous vessels and angiospasm, transcatheter arterial embolization using an n-butyl cyanoacrylate (NBCA)-lipiodol mixture was successfully performed. Fifty days later, the patient developed sudden abdominal pain again. Repeated angiography demonstrated recanalization of the splenic artery and splenic artery aneurysm. This time, the recanalized aneurysm was embolized using metallic coils with the isolation method. Physicians should keep in mind that recanalization can occur after transcatheter arterial embolization using N-butyl cyanoacrylate, which has been used as a permanent embolic agent.

    To describe when and how to perform endovascular embolization of aortic branch artery pseudoaneurysms associated with type A and type B intramural hematoma (IMH) involving the descending thoracic and abdominal aorta (DeBakey I and III) that increased significantly in size during follow-up. Sixty-one patients (39 men; mean {+-} standard deviation age 66.1 {+-} 11.2 years) with acute IMH undergoing at least two multidetector computed tomographic examinations during follow-up for 12 months or longer were enrolled. Overall, 48 patients (31 men, age 65.9 {+-} 11.5) had type A and type B IMH involving the descending thoracic and abdominal aorta (DeBakey I and III). Among the 48 patients, 26 (54 %; 17 men, aged 64.3 {+-} 11.4 years) had 71 aortic branch artery pseudoaneurysms. Overall, during a mean follow-up of 22.1 {+-} 9.5 months (range 12-42 months), 31 (44 %) pseudoaneurysms disappeared; 22 (31 %) decreased in size; two (3 %) remained stable; and 16 (22 %) increased in size. Among the 16 pseudoaneurysms with increasing size, five of these (three intercostal arteries, one combined intercostobronchial/intercostal arteries, one renal artery), present in five symptomatic patients, had a significant increase in size (thickness >10 mm; width and length >20 mm). These five patients underwent endovascular embolization with coils and/or Amplatzer Vascular Plug. In all patients, complete thrombosis and exclusion of aortic pseudoaneurysm and relief of back pain were achieved. Aortic branch artery pseudoaneurysms associated with type A and type B IMH involving the descending thoracic and abdominal aorta (DeBakey I and III) may be considered relatively benign lesions. However, a small number may grow in size or extend longitudinally with clinical symptoms during follow-up, and in these cases, endovascular embolization can be an effective and safe procedure.

    Purpose: This study was designed to evaluate the radiologic findings and imaging response of chemoembolization via branches of the splenic artery in patients with hepatocellular carcinoma (HCC). Methods: From January 2001 to July 2010, we observed tumor staining supplied by branches of the splenic artery in 34 (0.6%) of 5,413 patients with HCC. Computed tomography (CT) scans and digital subtraction angiograms of these patients were retrospectively reviewed in consensus by two investigators. Results: A total of 39 tumor feeding-vessels in 34 patients were identified: omental branches from the left gastroepiploic artery (n = 5), branches from the short gastric artery (n = 9), and omental branches directly from the splenic artery (n = 25). Branches of the splenic artery that supplied tumors were revealed on the celiac angiogram in 29 (85%) of 34 patients and were detected on pre-procedure CT images in 27 (79%) of 34 patients. Selective chemoembolization was achieved in 38 of 39 tumor-feeding vessels. Complete or partial response of the tumor fed by branches of the splenic artery, as depicted on follow-up CT scans, was achieved in 21 (62%) patients. No patient developed severe complications directly related to chemoembolization via branches of the splenic artery. Conclusions: Omental branches directly from the splenic artery are common tumor-feeding vessels of the splenic artery in cases of advanced HCC with multiple previous chemoembolizations. Tumor-feeding vessels of the splenic artery are usually visualized on the celiac angiogram or CT scan, and chemoembolization through them can be safely performed in most patients.

    Full Text Available Although uncommon, bleeding following pancreaticoduodenectomy is associated with high mortality. Management generally includes surgical reexploration or, alternatively, transarterial embolization. We report the case of a 62-year-old man who presented with massive upper gastrointestinal bleeding 3 weeks after pancreaticoduodenectomy. Selective coeliac angiography revealed a large pseudoaneurysm involving the proper hepatic artery. This was treated successfully with a stent graft. There was no recurrence of bleeding at the 6-month follow-up. To our knowledge, this is the first report of stent graft repair of bleeding hepatic artery pseudoaneurysm following pancreaticoduodenectomy.

    Dissection of the cervical segment of the internal carotid artery may occur spontaneously or after trauma. We report the management of a 53-year-old right-handed man with progressive dizziness and neck pain 6 weeks after a motor vehicle collision. The clinical and neurologic examinations were normal. The CT scan led to the diagnosis of a pseudoaneurysm of the right internal carotid artery near the skull base. We successfully treated this post-traumatic lesion with a covered stent. The patient underwent the endovascular procedure under general anesthesia and transcranial Doppler monitoring. No neurologic event was observed. Obliteration of the pseudoaneurysm with preservation of the carotid artery was achieved. The patient was discharged from the hospital 72 hr later with no complications. Clinical and imaging follow-up at 6 months was unremarkable

    Full Text Available Pseudoaneurysms of the subclavian artery remain a rare complication after fracture of the clavicle. We report a case of delayed diagnosis of a subclavian artery pseudoaneurysm after a closed fracture of the clavicle in a 15-year-old patient, 3 months after the original injury while playing rugby union. Despite several attendances to the Emergency Department with vague symptoms, the final diagnosis was confirmed by duplex ultrasound and Computed Tomography of the thorax. Surgical repair was indicated due to acute limb ischaemia from distal embolisation from a large pseudoaneurysm, with the patient making a full recovery. This case highlights the need for clinical vigilance when assessing patients, particularly on repeated occasions when their recovery appears to be impaired. A thorough history and clinical examination can raise suspicion of even rare occurrences and aid prompt management.

    Pseudoaneurysms of the cervical internal carotid artery (ICA) are rare and most frequently result from trauma, infection, or sometimes spontaneously. They have the potential to cause life-threatening hemorrhage; thus, their immediate management is necessary. Endovascular treatment by stent graft placement in the affected artery appears to be a safe and effective treatment option. We present a case of a child who presented with neck swelling and dysphagia caused by a ruptured cervical ICA pseudoaneurysm which was managed by stent graft placement.

    Post-traumatic pseudoaneurysms of the extracranial arteries in the scalp are uncommon sequelae of head injury. We report on a patient who presented four weeks after a minor head injury with a tender, pulsating and enlarging mass in the course of the left occipital artery. There was associated headache radiating to the vertex. Computed tomographic angiography confirmed the lesion to be a pseudoaneurysm of the occipital artery. The lump was resected with complete resolution of symptoms.

    Full Text Available Infected pseudoaneurysm of the femoral artery represents a devastating complication of intravenous drug abuse, especially in the event of rupture. Operative strategy depends upon the extent of arterial injury and the coexistence of infection or sepsis. Options range from simple common femoral artery (CFA ligation to complex arterial reconstruction with autologous grafts (arterial, venous, or homografts. We report herein the management of a 29-year-old male patient who was urgently admitted with a ruptured pseudoaneurysm of the right CFA, extending well above the inguinal ligament. Multidisciplinary approach with multiple arterial reconstructions and subsequent coverage of the tissue defect with a rectus abdominis musculocutaneous flap transposition was performed.

After 6 months splenic volume was assessed by CT, and IgM memory B cells in peripheral blood were measured and compared to a local normal reference population and to a post-splenectomy population.ResultsOf the 71 patients who underwent embolisation, 38 underwent proximal embolisation, 11 underwent distal embolisation, 22 patients were excluded, 1 had both proximal and distal embolisation, 5 did not survive and 16 did not return for evaluation. There was a significant difference between splenectomy and proximal or distal embolisation and a trend towards greater preservation of IgM memory B cell number in those with distal embolisation—a difference that could not be attributed to differences in age, grade of injury or residual splenic volume.ConclusionIgM memory B cell levels are significantly higher in those treated with SAE compared to splenectomy. Our data provide evidence that splenic embolisation should reduce immunological complications of spleen trauma and suggest that distal embolisation may maintain better function

    A 68-year-old woman presenting with gastrointestinal bleeding (hematocrit 19.3%) and in a critical clinical condition (American Society of Anesthesiologists grade 4) from a giant superior mesenteric artery pseudoaneurysm (196.0 x 131.4 mm) underwent emergency endovascular treatment. The arterial tear supplying the pseudoaneurysm was excluded using a 5.0 mm diameter and 31 mm long monorail expanded polytetrafluoroethylene (ePTFE)-covered self-expanding nitinol stent. Within 6 days of the procedure, a gradual increase in hemoglobin levels and a prompt improvement in the clinical condition were observed. Multislice CT angiograms performed immediately, 5 days, 30 days and 3 months after the procedure confirmed the complete exclusion of the pseudoaneurysm

    Purpose. To assess the feasibility and effectiveness of endovascular treatment of splenic artery aneurysm (SAAs). Materials and methods. Between May 2000 and June 2003 we treated 11 true SAAs in 9 patients (7 females and 2 males; mean age 58 years), 8 saccular and 3 fusiform, 4 located at the middle tract of the splenic artery, 5 at the distal tract and 2 intra-parenchymal. The diagnosis was performed with colour-Doppler ultrasound and/or CT-angiography; 7 patients were symptomless, 1 had left hypochondriac pain, and 1 had acute abdomen caused by a ruptured SAA. Four SAAs were treated by micro coil embolisation of the aneurysmal sac with preservation of splenic artery patency; in 2 cases this was associated with transcatheter injection of N-butyl-2-cyanoacrylate. Four cases were treated by endovascular ligature, with sectoral spleen ischaemia. One ruptured SAA received emergency treatment with splenic artery cyanoacrylate embolisation. Two intra-parenchymal SAAs were excluded, one by cyanoacrylate embolisation of the afferent artery and the other by transcatheter thrombin injection in the aneurysmal sac. Results. Technical success was observed in all cases (in 10/11 at the end of the procedure; in 1/11 at CT performed 3 days after the procedure). The follow-up (mean 18 months; range 6-36) was performed by colour-Doppler ultrasound and/or CT-angiography 3, 6 and 12 months after the procedure and subsequently once a year; the complete exclusion of the aneurysms was confirmed in 11/11 cases. The complications were: 4 cases of mild pleuritis; fever and left hypochondriac pain 1 day after the procedure (in the same 4 patients and in one other case); 5 cases of sectorial spleen ischaemia and 1 case of diffuse spleen infarction with partial revascularization by collateral vessels. No alteration of the levels of pancreatic enzymes was found; a transitory increase in platelet count occurred only in the patient with diffuse spleen infarction. Conclusions. Using different

    Although aneurysmal complications of sickle cell anemia have been described in the intracranial circulation, visceral artery pseudoaneurysms in this disease entity have not previously been reported in the literature. Conventional treatment of visceral pseudoaneurysms has been surgical ligation or resection of the aneurysm. Transcatheter embolization has emerged as an attractive, minimally invasive alternative to surgery in the treatment of these lesions. In certain situations, however, due to the unfavorable angiographic anatomy precluding safe transcatheter embolization, direct percutaneous glue injection of the pseudoaneurysm sac may be considered to achieve successful occlusion of the sac. The procedure may be rendered safer by simultaneous balloon protection of the parent artery. We describe this novel treatment modality in a case of inferior pancreaticoduodenal artery pseudoaneurysm in a patient with sickle cell anemia. Although a complication in the form of glue reflux into the parent vessel occurred that necessitated surgery, this treatment modality may be used in very selected cases (where conventional endovascular embolization techniques are not applicable) after careful selection of the balloon diameter and appropriate concentration of the glue-lipiodol mixture

    To introduce pseudoaneurysm of the sphenopalatine artery as the possible aetiology of acute massive epistaxis in patients with a history of orthognathic surgery accompanied by Le Fort I osteotomy. Case report and literature review. This paper reports a case of acute life-threatening epistaxis following Le Fort I osteotomy. Computed tomography and angiography showed a pseudoaneurysm of the sphenopalatine artery, which was successfully treated by endovascular embolisation. Although a pseudoaneurysm of the sphenopalatine artery following Le Fort I osteotomy is extremely rare, it should be considered as the possible aetiology of acute massive epistaxis in patients with a history of orthognathic surgery accompanied by Le Fort I osteotomy.

    Aneurysms of the splenic artery are the most common splanchnic aneurysms. Aneurysms of a splenic artery with an anomalous origin from the superior mesenteric artery are however rare, with eight previously reported cases. Their indications for treatment are superposable to those of aneurysms affecting an orthotopic artery. Methods of treatment of this condition include endovascular, minimally invasive techniques and surgical resection. We report one more case of aneurysm of an aberrant splenic artery, treated with surgical resection, and preservation of the spleen.

    Full Text Available Background. Rupture of a splenic artery aneurysm is rare complication of pregnancy that is associated with a significant maternal and fetal mortality. Case. A multiparous female presented in the third trimester with hypotension, tachycardia, and altered mental status. A ruptured splenic artery aneurysm was discovered at the time of laparotomy and cesarean delivery. The patient made a full recovery following resection of the aneurysm. The neonate survived but suffered severe neurologic impairment. Conclusion. The diagnosis of ruptured splenic artery aneurysm should be considered in a pregnant woman presenting with signs of intra-abdominal hemorrhage. Early intervention by a multidisciplinary surgical team is key to preserving the life of the mother and fetus.

    Full Text Available Abstract Introduction This is the first case report of Mirizzi syndrome associated with hepatic artery pseudoaneurysm. Case presentation A 54-year-old man presented with painful obstructive jaundice and weight loss. Computed tomography showed a hilar mass in the liver. Following an episode of haemobilia, angiography demonstrated a pseudoaneurysm of a branch of the right hepatic artery that was embolised. At surgery, a gallstone causing Mirizzi type II syndrome was found to be responsible for the biliary obstruction and a necrotic inflammatory mass and haematoma were found to be extending into the liver. The mass was debrided and drained, the obstructing stones removed and the bile duct drained with a t-tube. The patient made a full recovery. Conclusion This case highlights another situation where there may be difficulty in differentiating Mirizzi syndrome from biliary tract cancer.

    A plethora of papers have been written regarding postcatheterization femoral pseudoaneurysms. However, literature is lacking on pseudoaneurysmal management in patients undergoing coronary artery bypass grafting (CABG). Thus, we examined if pseudoaneurysms with subsequent CABG can be managed with the same strategies as those not exposed to the intense anticoagulation accompanying CABGs. During a 14-year study period, we retrospectively examined femoral iatrogenic pseudoaneurysms (IPSAs) diagnosed postheart catheterization in patients having a subsequent CABG. Patient information was obtained from electronic medical records and included pseudoaneurysm characteristics, treatment, and resolution. Outcomes of interest included the occurrence of IPSA treatment failures and complications. In the 66 patients (mean age, 66 ± 11 years, 46% male) meeting inclusion criteria, mean dose of heparin received during the CABG procedure was 34 000 ± 23 000 units. The IPSA size distribution was the following: 17% of IPSAs measured 3 cm. Pseudoaneurysms were managed with compression, duplex-guided thrombin injection, and surgical repair (1%, 27%, and 26% of cases, respectively). Thrombin injection and surgical repair were 100% effective at treating pseudoaneurysms, with 1 patient experiencing a surgical site infection postsurgical repair. Observation-only management was employed in 30 (45%) patients. Nine of 30 patients with no intervention beyond observation had duplex documented resolution/thrombosis during follow-up. One patient initially managed by observation required readmission and surgical repair of an enlarging pseudoaneurysm (6 cm growth) following CABG. Management of pseudoaneurysms in patients prior to CABG should be similar to those patients not undergoing intense anticoagulation. In appropriate cases, small aneurysms can be safely observed, while thrombin injections are effective and safe as well. Thus, routine open surgical repair is not routinely required in patients

    We present the case of a 60-year-old man with persistent epistaxis for 20 days that had started 2 weeks after removal of a nasogastric tube placed for an abdominal operation. There was no pathologic finding at selective facial and internal maxillary artery injections. An injury to the ethmoidal branches of the ophthalmic arteries or other arterial origins of bleeding was suspected. The internal carotid artery angiography revealed a pseudoaneurysm of an anterior ethmoidal branch of the left ophthalmic artery. The pseudoaneurysm was occluded with NBCA-histoacryl (25%) injection.

    The primary treatment of nasopharyngeal carcinoma (NPC) has been external radiotherapy. Rupture of an internal carotid artery (ICA) pseudoaneurysm is a rare complication of irradiation therapy for a nasopharyngeal carcinoma. A 78 years old man had a history of NPC treated with radiotherapy in 1993. He was admitted to the hospital because of epistaxis. Angiography showed an ICA pseudoaneurysm pointing medially to the nasopharynx. Coil embolization of the ICA was performed, but cerebral infarction occurred. Internal carotid artery (ICA) pseudoaneurysms are an uncommon but potentially lethal condition. Angiography is the mainstay of diagnosis of the aneurysm and planning the embolization of the ICA. We should be more aware of this complication in NPC patients. (author)

  15. Tortuosity and calcification of the splenic artery. More than an additional finding

    International Nuclear Information System (INIS)

    Golder, W.A.

    2008-01-01

    Tortuosity of the splenic artery and calcification of the vessel wall are typical additional findings on plain abdominal x-ray. The combination of both anomalies is common in elderly persons presenting without symptoms of splenic ischemia. Its pathogenesis is thought to be multifactorial. In infancy and childhood, the splenic artery is stretched in its entire course. A growing difference between the length of the vessel and the distance between its origin and the splenic hilum gives rise to tortuosity. The artery's proximal segment is involved more frequently and more severely than the distal one. The tortuous route of the vessel is accentuated by the direction of its major branches, which is roughly perpendicular to the main trajectory. Neither tortuosity nor calcification should be taken to be risk factors for the comparatively common splenic artery aneurysm. Calcific deposits are not confined to the media but are also detected in the intima of the vascular wall. Critical narrowings of the lumen arising on the calcium deposits are not observed. Calcifying atherosclerosis of the splenic artery is comparable to medial sclerosis of the peripheral arteries frequently noticed in diabetics and dialysis patients. Only the less important calcification of the intima may be attributed to mechanisms of the hydrohemodynamic theory of atherosclerosis. The spleen's blood storage capacity may contribute to the characteristic age-dependent alterations of the shape and course of the splenic artery. (orig.) [de

    Objective: To evaluate the efficacy and mid-term follow-up results of endovascular treatment with Willis covered stent for traumatic pseudoaneurysms located in the internal carotid artery (ICA). Methods: ICA angiography was performed in 38 patients with traumatic brain and neck injury. Of the 38 patients, 13 delayed traumatic pseudoaneurysms were found. All the pseudoaneurysms were treated with Willis covered stents. Follow-up angiography was performed at 1, 3, 6 and 12 months after the procedure, and the results were categorized as complete or incomplete occlusion. Clinical manifestations were graded as full recovery, improvement, unchanged and aggravation. Results: Willis covered stent placement was technically successful in all traumatic pseudoaneurysms. No procedure-related complications occurred. The initial angiographic results showed a complete occlusion in 9 patients, and an incomplete occlusion in 4. The angiographic follow-up within 3-12 months exhibited a complete occlusion in 12 patients and the parent arteries remained patency in all patients. The clinical follow-up observation demonstrated that full recovery was obtained in 11 patients, clinical improvement in one, and unchanged condition in one. No morbidity or mortality occurred. Conclusion: Willis covered stent implantation is a feasible and practical treatment for traumatic pseudoaneurysms located in the ICA. This technique can well preserve the parent artery with excellent therapeutic results. (authors)

    Most published articles regarding orthopedic- and trauma-related femoral artery pseudoaneurysms (FAPs) are case reports in English. Reported cases are often associated with a literature review but actually provide little robust data. We wanted to summarize the current knowledge on diagnostic and therapeutic features of these FAPs. A new case of superficial FAP is described followed by a review of the literature. A bibliographic search was performed online (PubMed, ScinceDirect) from 1964 to 2015 using the descriptors "traumatic femoral pseudoaneurysm, orthopedic surgery, osteochondroma". A total of 64 cases of FAPs was analyzed. There were 50 men with an average age of 40.72±26.45 years old. The most common clinical presentation was painful swelling (34%). Arteriography was the commonest radiological investigation used (63%). The main etiologies were orthopedic injuries (47%), surgery of the upper thigh (30%) and femoral osteochondromas (23%). Arterial injuries included superficial femoral (47%) and profunda femoris artery (50%). The treatment was open surgery (56%) or endovascular repair (36%). Deep femoral artery and its branches were embolized (47%) or ligated (38%). Endovascular stenting was performed in 30% of posttraumatic FAPs. All FAPs relating to osteochondromas were repaired surgically. Postoperative courses were uneventful in 95% of patients. Endovascular embolization is preferred in management of postsurgical FAPs which have usually involved the deep femoral artery. Endovascular stenting graft may be proposed for posttraumatic FAPs, for which the superficial femoral trunk is the most often involved vessel. Surgical repair should be performed when endovascular stenting graft is not feasible. Surgical repair is mandatory for all FAPs secondary to traumatic exostoses. Copyright © 2015 Elsevier Masson SAS.

    We present a 16-year-old boy with autoimmune liver disease and longstanding portal hypertension in whom a CT arteriogram demonstrated a large aneurysm arising from the distal, extra-parenchymal portion of the splenic artery. Because of its location adjacent to multiple venous collaterals, the aneurysm was indistinguishable from splenic varices on initial imaging with Doppler sonography and on portal venous-phase CT. There is an increased risk of rupture of splenic artery aneurysms in the post-liver transplant period, with high associated mortality, and therefore diagnosis of splenic artery aneurysm prior to liver transplantation is clinically important. It is quite possible that the diagnosis of splenic artery aneurysm in this case would have been missed in the absence of dedicated arterial-phase imaging. As radiologists strive to reduce radiation exposure in children, this case highlights a potential diagnostic pitfall of both Doppler sonography and venous or single-acquisition arterial/venous-phase CT angiogram in children with venous collaterals and an undiagnosed splenic artery aneurysm.

  1. Pseudoaneurysm of the Anterior Tibial Artery following Ankle Arthroscopy in a Soccer Player

    Ichiro Tonogai

    2017-01-01

    Full Text Available Ankle arthroscopy carries a lower risk of vascular complications when standard anterolateral and anteromedial portals are used. However, the thickness of the fat pad at the anterior ankle affords little protection for the thin-walled anterior tibial artery, rendering it susceptible to indirect damage during procedures performed on the anterior ankle joint. To our knowledge, only 11 cases of pseudoaneurysm involving the anterior tibial artery after ankle arthroscopy have been described in the literature. Here we reported a rare case of a 19-year-old soccer player who presented with pseudoaneurysm of the anterior tibial artery following ankle arthroscopy using an ankle distraction method and underwent anastomosis for the anterior tibial artery injury. Excessive distraction of the ankle puts the neurovascular structures at greater risk for iatrogenic injury of the anterior tibial artery during ankle arthroscopy. Surgeons should look carefully for postoperative ankle swelling and pain after ankle arthroscopy.

    Objective: To create a further understanding of the angiographic features of the carotid artery pseudoaneurysm (CAPA) and to explore the clinical diagnostic value of angiography. Methods: Sixteen cases of CAPA with clinical and angiographic data were analyzed retrospectively. The angiographic appearances in all of the patients were observed dynamically and precisely with a double blind method by two experienced radiologists together and formed a consensus interpretation. Results: Angiography provided a definite diagnosis for all cases. The parent arteries included the common carotid artery (1 case), common carotid artery bifurcation (9 cases), internal carotid artery (5 cases) and external carotid artery (1 case). The angiographic features of the CAPA were: All cases showed the contrast media retension in the aneurysms; turbulent flow within aneurysm in 9 cases; the 'jetting sign' at the leak of the parent artery in 7 cases; increase angulation of the bifurcation of internal and external carotid arteries in 12 cases. Conclusions: Angiography is the most valuable examination method in diagnosis of CAPA, and it can not only provide definite diagnosis, but also play an important role in selection of therapeutic plan.

    The spleen is the most commonly injured visceral organ in blunt abdominal trauma in both adults and children. Nonoperative management is the current standard of practice for patients who are hemodynamically stable. However, simple observation alone has been reported to have a failure rate as high as 34%; the rate is even higher among patients with high-grade splenic injuries (American Association for the Surgery of Trauma [AAST] grade III-V). Over the past decade, angiography with transcatheter splenic artery embolization, an alternative nonoperative treatment for splenic injuries, has increased splenic salvage rates to as high as 97%. With the help of splenic artery embolization, success rates of more than 80% have also been described for high-grade splenic injuries. We discuss the role of computed tomography and transcatheter splenic artery embolization in the diagnosis and treatment of blunt splenic trauma. We review technical considerations, indications, efficacy and complication rates. We also propose an algorithm to guide the use of angiography and splenic embolization in patients with traumatic splenic injury.

    Techniques of mixed reality can successfully be used in preoperative planning of laparoscopic and robotic procedures and to guide surgical dissection and enhance its accuracy. A computer-generated three-dimensional (3D) model of the vascular anatomy of the spleen was obtained from the computed tomography (CT) dataset of a patient with a 3-cm splenic artery aneurysm. Using an environmental infrared localizer and a stereoscopic helmet, the surgeon can see the patient's anatomy in transparency (augmented or mixed reality). This arrangement simplifies correct positioning of trocars and locates surgical dissection directly on top of the aneurysm. In this way the surgeon limits unnecessary dissection, leaving intact the blood supply from the short gastric vessels and other collaterals. Based on preoperative planning, we were able to anticipate that the vascular exclusion of the aneurysm would result in partial splenic ischemia. To re-establish the flow to the spleen, end-to-end robotic anastomosis of the splenic artery with the Da Vinci surgical system was then performed. Finally, the aneurysm was fenestrated to exclude arterial refilling. The postoperative course was uneventful. A control CT scan 4 weeks after surgery showed a well-perfused and homogeneous splenic parenchyma. The final 3D model showed the fenestrated calcified aneurysm and patency of the re-anastomosed splenic artery. The described technique of robotic vascular exclusion of a splenic artery aneurysm, followed by re-anastomosis of the vessel, clearly demonstrates how this technology can reduce the invasiveness of the procedure, obviating an otherwise necessary splenectomy. Also, the use of intraoperative mixed-reality technology proved very useful in this case and is expected to play an increasing role in the operating room of the future.

    The purpose of this study is to evaluate the efficacy of transcatheter arterial embolization (TAE) in children with blunt splenic injury. The results of transcatheter splenic arterial embolization in nine children who suffered splenic injury after blunt abdominal trauma were retrospectively studied. This injury was demonstrated by CT, and the findings were evaluated according to the classification of Mirvis et al.; two patients were grade 3 and seven were grade 4. All were carefully observed in intensive care before embolization. TAE was performed if a patient satisfied the following criteria : (1) transfusion and/or fluid replacement required to maintain hemodynamic stability; or (2) rapid Hb/Hct decrease; or (3) both. Splenic function was subsequently estimated according to the results of 09m Tc-sulfur colloid scintigraphy and/or CT scanning. TAE was successful in all nine children. Two were embolized with a coil only, three with gelfoam, and four with gelfoam and a coil. Seven were embolized in the main trunk of the splenic artery and others in both the main trunk and its branches. Splenic function was preserved in all nine children, during follow-up, none suffered rebleeding. TAE of the splenic artery can be a safe and effective nonsurgical approach to the management of blunt splenic injury in children, and can preserve splenic function.

    Full Text Available A patient developed hemopericardium shortly after left brachial arterial embolectomy using an embolectomy catheter. Evaluation disclosed evolving pseudoaneurysm of the right coronary artery that was successfully managed by stenting. Misplacement of the embolectomy catheter within the coronary vessel was facilitated by an anomalous origin of the right coronary artery. This complication highlights the importance of correct insertion of the embolectomy catheter using the markers to avoid maladvancement and damage to central vessels.

    We report the successful repair of impending rupture of a pseudoaneurysm of the brachiocephalic artery (BCA) in a 70-year-old man. He had undergone a mediastinal tumor resection through a median sternotomy in 1995. Pathological examination revealed non-Hodgkin's lymphoma. Two years later, he underwent radiation therapy of 65 Gray for metastasis to the supraclavicular lymph nodes. On January 18, 2000, plastic surgeons planned to perform a pectoralis major musculocutaneous flap to repair a radiation skin ulcer. During the operation, the BCA was lacerated, possibly in an area of radiation tissue damage. We performed a prosthetic graft (10-mm Gelseal) replacement of the BCA. The right subclavian artery had to be ligated. Postoperative digital subtraction angiography (DSA) showed excellent reconstruction of the artery. Magnetic resonance angiography of the brain showed a deficit in the anterior communicating artery and stenosis of the posterior communicating artery, which indicated that the reconstruction procedure was reasonable. Seven months later, on August 18, 2000, the patient was transferred to our hospital because of swelling of the right neck and oozing from the previous cutaneous wound. CT scan and DSA demonstrated the presence of a pseudoaneurysm of the proximal anastomosis site, which required emergency surgery. Before this third sternotomy, a saphenous vein graft was interposed between both external carotid arteries. Removal of the prosthetic graft and resection of the pseudoaneurysm were performed under mild hypothermia and cardiopulmonary bypass with left common carotid arterial perfusion. Then, the wound was closed completely using a left pectoralis major musculocutaneous flap. The postoperative course was uneventful and DSA showed good patency of the graft and intracranial arteries. The patient was discharged without neurological complications. We conclude that prior reconstruction of the carotid artery is a safe and effective procedure for patients

    Case report: A 59-year-old male presented to our department with bony ankylosis of his temporomandibular joints bilaterally as a result of previous osteomyelitis. He underwent bilateral temperomandibular joint replacements in a two-stage procedure. Six weeks post discharge he presented to the emergency department in haemorrhagic shock, having lost significant blood volume from a pulsatile lesion over his right mandible. Computed tomography angiography revealed a pseudoaneurysm of the right facial artery. He proceeded to emergent embolisation with resolution of the pseudoaneurysm.

    To characterize extrahepatic pseudoaneurysm regarding incidence and etiology and determine the effectiveness of endovascular management. A retrospective audit of 1,857 liver transplants in two institutions was performed (1996–2009). Recipients’ demographics, clinical presentation, transplant type, biliary anastomosis, and presence of biliary endoprostheses were noted. Pseudoaneurysms were classified into iatrogenic (associated with biliary endoprosthesis or angioplasty) or spontaneous extrahepatic pseudoaneurysms. Spontaneous and iatrogenic pseudoaneurysms were compared for time from transplant, presenting symptoms, location in the arterial anatomy, and 3-month graft survival. Arterial patency and 6-month graft survival were calculated. Twenty pseudoaneurysms were found (1.1 %, 20/1,857): 9 (0.5 % of transplants, 9/1,857) were spontaneous and 11 (0.6 % of transplants, 11/1,857) were “iatrogenic” (due to minimally invasive procedures: 4 angioplasty and 7 biliary endoprostheses). Sixty percent (12/20) underwent endovascular management (4 coil embolization and 8 stent-grafts). Technical success was 83 % (10/12) with a mean arterial patency of 70 % (follow-up mean, 4.9; range, 0–18 months). The 1-, 3-, and 6-month graft survival was 70, 40, and 35 %, respectively. Due to minimally invasive procedures, posttransplant extrahepatic pseudoaneurysms are no longer an exclusive complication of the transplant surgery itself. Endovascular management is effective to stabilize patients but has not improved historic postsurgical graft survival.

    To objectively demonstrate the gain in blood volume and blood components following early ligation of splenic artery during splenectomy and splenorenal shunts in children with extra hepatic portal venous obstruction (EHPVO). Twenty-eight children (20 males and 8 females, mean age: 9.9 (+/-3.2) years) with EHPVO and hypersplenism were recruited. We followed a protocol of systematically locating and ligating the splenic artery first, followed by a 30-minute waiting period to allow the massive spleen to decongest via the splenic vein and venous collaterals and then completing the splenectomy by standard procedure. No intravenous fluid was administered during this 30-minute period. Blood samples were drawn just prior to splenic artery ligation and soon after splenectomy for the estimation of hematological and biochemical parameters. We noticed a highly significant increase in the hemoglobin, hematocrit, leukocyte, platelet, and RBC counts by early ligation of the splenic artery (p platelet count was equivalent to a platelet transfusion of atleast 4 units of platelet concentrates in an adult. There is a positive correlation between the splenic weight and the platelet gain (p= 0.0568) and the splenic volume on preoperative imaging and the platelet gain (p= 0.0251). Early ligation of the splenic artery during splenectomy results in passive splenic decongestion and thereby a significant gain in blood components. This protocol appears to be a feasible blood conservation method to avoid blood transfusions in this group of hypersplenic EHPVO patients.

  2. Pseudoaneurisma gigante de artéria esplênica

    Orlando Jorge Martins Torres

    Full Text Available Splenic artery pseudoaneurysm larger than 10 cm is a rare condition. The risk of rupture is probably high and surgical treatment is necessary. The objective of this article is to report a case of a patient with giant pseudoaneurysm of the splenic artery submitted to surgical resection. A 26-year-old man complaining of gastrointestinal hemorrhage and abdominal pain The patient’s medical history revealed that one year before he had an abdominal blunt trauma. The angiography showed a giant pseudoaneurysm of the splenic artery with compression of the stomach. The patient was operated on by abdominal access and the spleen and pseudoaneurysm were resected. The postoperative course was uneventful and the patient was discharged 13 days after surgery without problems.

    A novel case is reported of upper gastrointestinal (UGI) bleeding from sinistral portal hypertension, caused by a left gastric artery (LGA) pseudoaneurysm (PA) compressing the splenic vein (SV) that was successfully treated with PA embolization. A 41-year-old man with previous medical history of recurrent, alcoholic pancreatitis presented with several episodes of hematemesis and abdominal pain for 48 hours. Physical examination revealed a soft abdomen, with no abdominal bruit, no pulsatile abdominal mass, and no stigmata of chronic liver disease. The hemoglobin declined acutely from 12.3 to 9.3 g/dL. Biochemical parameters of liver function and routine coagulation profile were entirely within normal limits. Abdominal CT revealed a 5-cm-wide peripancreatic mass compressing the stomach and constricting the SV. Esophagogastroduodenoscopy showed blood oozing from portal hypertensive gastropathy, small nonbleeding gastric cardial and fundal varices, gastric compression from the extrinsic mass, and no esophageal varices. MRCP and angiography showed that the mass was vascular, arose from the LGA, compressed the mid SV without SV thrombosis, and caused sinistral portal hypertension. At angiography, the PA was angioembolized and occluded. The patient has been asymptomatic with no further bleeding and a stable hemoglobin level during 8 weeks of follow-up. Literature review of the 14 reported cases of LGA PA revealed that this report of acute UGI bleeding from sinistral portal hypertension from a LGA PA constricting the SV is novel; one previously reported patient had severe anemia without acute UGI bleeding associated with sinistral portal hypertension from a LGA PA. A patient presented with UGI bleeding from sinistral portal hypertension from a LGA PA compressing the SV that was treated by angiographic obliteration of the PA which relieved the SV compression and arrested the UGI bleeding. Primary therapy for this syndrome should be addressed to obliterate the PA and not

    Purpose: To evaluate the safety and efficacy of the Amplatzer vascular plug (AVP) for embolization of the splenic artery in patients with hepatic hypoperfusion after orthotopic liver transplantation (OLT). Materials and Methods: Thirteen patients (9 men and 4 women) with a mean age of 56 years (range 22–70) who developed splenic artery syndrome after OLT with decreased liver perfusion and clinically relevant impairment of liver function (increased transaminase or serum bilirubin levels, thrombocytopenia, and/or therapy-refractory ascites) were treated by embolization of the proximal third of the splenic artery using the AVP. The plugs ranged in diameter from 6 to 16 mm, and they were introduced through femoral (n = 9), axillary (n = 3), or brachial (n = 1) access using a 5F or 8F guiding catheter. Results: The plugs were successfully placed, and complete occlusion of the splenic artery was achieved in all patients. Placement of two plugs was necessary for complete occlusion in 3 of the 13 patients. Occlusion took on average 10 min (range 4–35). There was no nontarget embolization or plug migration into more distal segments of the splenic artery. All patients showed improved arterial perfusion, including the liver periphery, on postinterventional angiogram. After embolization, liver function parameters (transaminase and bilirubin levels) improved with normalization of concomitant thrombocytopenia and a decrease in ascites volume. Conclusion: Our initial experience in a small patient population with SAS suggests that the AVP enables precise embolization of the proximal splenic artery, thus providing safe and effective treatment for poor liver perfusion after OLT due to SAS.

    A 40-year-old man, a chronic alcoholic, presented with acute epigastric pain. Selective celiac arteriography showed a pseudoaneurysm arising from the common hepatic artery. We hereby describe a technical innovation where complete pseudoaneurysm exclusion was seen after intra-aneurysmal N-butyl 2-cyanoacrylate (glue) injection with preservation of antegrade hepatic arterial flow and conclude that intra-aneurysmal liquid injection may have potential as a therapeutic option to reconstruct a defective vessel wall and thereby maintain the antegrade flow

    Objective: To analyze the reaction of splenic arterial embolization (embolization syndromes) using 3 different materials together with the therapeutic methods. Methods: Thirty nine patients of cirrhosis with hypersplenism and hypersplenotrophy, 11 of them were treated with steel coils, 15 with gelfoam, 13 with the PVA. The embolized area was approximately 60% of the whole splenic area. Results: Thirty nine cases obtained the curative effect. The blood white cell and platelet counts were normal or close to normal. The rates of splenic pain in steel coils group, gelfoam group and PVA group were 81.8%, 100% and 100% respectively. The duration of serious pain were 2-5 d, 1-7 d and 1-7 d in coil group, gelfoam group and PVA group respectively. 33 patients had moderate fever around 38.5 degree C and 8 patients had eructation after embolization. The symptoms disappeared after using antibiotics, dexamethasone and analgesic. Conclusions: The algetic grade of splenic arterial embolization was inverse proportional with the size of embolus. The correct management could effectively control the symptoms of postembolization of the spleen

    PurposeTo describe the incidence of multiple renal artery pseudoaneurysms (PSA) in patients referred for renal artery embolization following partial nephrectomy and to study its relationship to RENAL nephrometry scores.Materials and MethodsThe medical records of 25 patients referred for renal artery embolization after partial nephrectomy were retrospectively reviewed for the following parameters: size and number of tumors, RENAL nephrometry scores, angiographic abnormalities, technical and clinical outcomes, and estimated glomerular filtration rates (eGFRs) after embolization.ResultsTwenty-four patients had primary renal tumors, while 1 patient had a pancreatic tumor invading the kidney. Multiple tumors were resected in 4 patients. Most patients (92 %) were symptomatic, presenting with gross hematuria, flank pain, or both. Angiography revealed PSA with (n = 5) or without (n = 20) AV fistulae. Sixteen patients (64 %) had multiple PSA involving multiple renal vessels. Higher RENAL nephrometry scores were associated with an increasing likelihood of multiple PSA. Multiple vessels were embolized in 14 patients (56 %). Clinical success was achieved after one (n = 22) or two (n = 3) embolization sessions in all patients. Post-embolization eGFR values at different time points after embolization were not significantly different from the post-operative eGFR.ConclusionA majority of patients requiring renal artery embolization following partial nephrectomy have multiple pseudoaneurysms, often requiring selective embolization of multiple vessels. Higher RENAL nephrometry score is associated with an increasing likelihood of multiple pseudoaneurysms. We found transarterial embolization to be a safe and effective treatment option with no long-term adverse effect on renal function in all but one patient with a solitary kidney.

    The traditional treatment of splenic artery aneurysm (SAA) is generally surgery and/or transcatheter arterial embolization, but recently, the treatment of SAA using a stent graft has been reported. However, the acute angle of the celiac axis, as well as the tortuous path of the splenic artery makes the use of stent graft difficult for treatment of aneurysma. We report here a case of SAA treated with the technique of double overlapping metallic stents

    We report a traumatic pseudoaneurysm of the internal carotid artery bifurcation and subclavian artery with recurrent strokes events in a 19-year-old man. He was admitted with an acute left hemiparesis. His history revealed a similar episode 1 year and a major car accident 3 years previously. Contrast enhanced MR angiography confirmed colour Doppler sonographic findings of a carotid and subclavian artery pseudoaneurysm presumably resulting from seat-belt trauma. The pseudoaneurysm, containing thrombus, was thought to be the source of artery-to-artery embolism. (orig.)

    Directory of Open Access Journals (Sweden)

    Simon Craxford

    2013-01-01

    Full Text Available This study reports the case of an 87-year-old woman who presented with a nonresolving haematoma 13 weeks following tibiotalar arthrodesis surgery on her right ankle using a retrograde nail. This was revealed by angiography to be a pseudoaneurysm of the anterior tibial artery. The patient subsequently underwent endovascular stenting of the pseudoaneurysm and has had a successful recovery. This case highlights the need for awareness of both the normal arterial supply to the leg and ankle as well as the potential for anatomical variations. Arterial variation may be as high as 6.7% based on published findings from cadaveric studies. As pseudoaneurysm is a rare complication, a high index of suspicion is needed in order to avoid a missed or delayed diagnosis. We urge surgeons to keep in mind the potential for pseudoaneurysm when a patient presents with a nonresolving haematoma and arrange appropriate further investigations as needed.

    Ultrasound-guided thrombin injection (UGTI) is a well-established practice for the treatment of femoral artery pseudoaneurysm. This procedure is highly successful but dependent on appropriate pseudoaneurysm anatomy and adequate ultrasound visualization. Morbid obesity can present a significant technical challenge due to increased groin adiposity, resulting in poor visualization of critical structures needed to safely perform the procedure. We aim to evaluate the safety and efficacy of UGTI to treat femoral artery pseudoaneurysm in the morbidly obese. This is a retrospective cohort study in which all patients who underwent UGTI at The Ohio State University Ross Heart Hospital from 2009 to 2014 were analyzed for patient characteristics and stratified by body mass index (BMI). Patients with BMI ≥ 35 were considered morbidly obese and were compared to patients with a BMI injection. There were 41 nonmorbidly obese and 13 morbidly obese patients. Mean age was 64.5 years. The cohort was 44.4% male. There were 6 failures, of which 1 underwent successful repeat injection and 5 underwent open surgical repair. There was no statistically significant difference in failure between nonmorbidly obese and morbidly obese patients (9.8% vs 15.4%, P = .45). There were no embolic/thrombotic complications. Ultrasound-guided thrombin injection is a safe and effective therapy in the morbidly obese for the treatment of femoral artery pseudoaneurysm. In the hands of experienced sonographers and surgeons with adequate visualization of the pseudoaneurysm sac, UGTI should remain a standard therapy in the morbidly obese.

    Hepatic artery pseudoaneurysms (HAP) are uncommon, occurring mostly as a complication of trauma (accidental or iatrogenic). Liver abscess rarely causes HAP and multiple HAP associated with cholangitic abscesses have not been reported in the literature. We present a patient of acute necrotizing pancreatitis with stent block cholangitis and multiple cholangitic abscesses who developed hemorrhagic output through drainage catheter in the liver abscess. A multiphasic CT angiography demonstrated three HAP, which were treated with a combination of endovascular coil embolization and percutaneous thrombin injection. The fact that cholangitic abscesses may be associated with pseudoaneurysms should not be neglected, considering the potentially catastrophic complication and relatively easy radiological management. CT angiography permits accurate diagnosis and lays down the roadmap for endovascular procedures

    Splenic Angioembolization (SAE), during Nonoperative Management (NOM) of Blunt Splenic Injury (BSI), is an effective therapy for hemodynamically stable patients with grade III, IV, and V OIS splenic injuries. We report a case of a patient with a blunt abdominal trauma due to an accidental fall, who presented splenic abscess a week after SAE and a review of the literature. A 38-year-old male arrived at Emergency after an accidental fall with contusion of the left upper quadrant of the abdomen. Abdominal CT scan revealed the fracture of the lower splenic pole with intraparenchymal pseudoaneurysms (OIS spleen injury scale IV). Considering the hemodynamic stability, NOM was undertaken and SAE was performed. After a week, the patient developed a splenic abscess confirmed by Abdominal CT; therefore, splenectomy was performed. There was no evidence of bacterial growing in the perisplenic hematoma cultures but the histological examination showed multiple abscess and hemorrhagic areas in the spleen. Splenic abscess after SAE during NOM of BSI is a rare major complication. The most frequently cultured organisms include Clostridium perfringens, Alpha-Hemoliticus Streptococcus, gram-positive Staphylococcus, gram-negative Salmonella, Candida, and Aspergillus. This case represents our first reported splenic abscess after SAE. SAE is a very useful tool for BSI managing; splenic abscess can occur in a short time, even if it is a rare major complication, so it may be useful to monitor patients undergoing SAE, focusing not only on the hemodynamic parameters but also on the inflammatory and infectious aspects.

  19. Hybrid endovascular and surgical approach for mycotic pseudoaneurysms of the extracranial internal carotid artery

    Full Text Available Objectives: Mycotic pseudoaneurysms of the extracranial internal carotid artery are rare, and their management often represents a challenge, but treatment is necessary due to the high risk of rupture and distal brain embolization. Systemic antibiotics associated with open surgical excision of the infected tissues and carotid reconstruction using autologous grafts are the treatment of choice. The use of endovascular techniques still remains controversial in infective fields; however, it can be an attractive alternative in high-risk patients or more often as a “temporary” solution to achieve immediate bleeding control for a safe surgical reconstruction. Methods: We discuss the unusual case of an extracranial right internal carotid artery mycotic pseudoaneurysm following methicillin-resistant Staphylococcus aureus infection, in a patient with poor general conditions. Results and Conclusion: The lesion was successfully treated using a hybrid endovascular and surgical procedure.

    Full Text Available Abstract Background Upper gastrointestinal haemorrhage is mainly caused by ulcers. Gastric varicosis due to portal hypertension can also be held responsible for upper gastrointestinal bleeding. Portal hypertension causes the development of a collateral circulation from the portal to the caval venous system resulting in development of oesophageal and gastric fundus varices. Those may also be held responsible for upper gastrointestinal haemorrhage. Case presentation In this study, we describe the case of a 69-year-old male with recurrent severe upper gastrointestinal bleeding caused by arterial submucosal collaterals due to idiopathic splenic artery thrombosis. The diagnosis was secured using endoscopic duplex ultrasound and angiography. The patient was successfully treated with a laparoscopic splenectomy and complete dissection of the short gastric arteries, resulting in the collapse of the submucosal arteries in the gastric wall. Follow-up gastroscopy was performed on the 12th postoperative week and showed no signs of bleeding and a significant reduction in the arterial blood flow within the gastric wall. Subsequent follow-up after 6 months also showed no further gastrointestinal bleeding as well as subjective good quality of life for the patient. Conclusion Submucosal arterial collaterals must be excluded by endosonography via endoscopy in case of recurrent upper gastrointestinal bleeding. Laparoscopic splenectomy provides adequate treatment in preventing any recurrent bleeding, if gastric arterial collaterals are caused by splenic artery thrombosis.

    AIM: To determine an optimal cutoff value for abnormal splenic artery diameter/proper hepatic artery diameter (S/P) ratio in cirrhosis-induced portal hypertension. METHODS: Patients with cirrhosis and portal hypertension (n = 770) and healthy volunteers (n = 31) underwent volumetric computed tomography three-dimensional vascular reconstruction to measure the internal diameters of the splenic artery and proper hepatic artery to calculate the S/P ratio. The cutoff value for abnormal S/P ratio was determined using receiver operating characteristic curve analysis, and the prevalence of abnormal S/P ratio and associations between abnormal S/P ratio and major complications of portal hypertension were studied using logistic regression. RESULTS: The receiver operating characteristic analysis showed that the cutoff points for abnormal splenic artery internal diameter and S/P ratio were > 5.19 mm and > 1.40, respectively. The sensitivity, specificity, positive predictive value, and negative predictive value were 74.2%, 45.2%, 97.1%, and 6.6%, respectively. The prevalence of an abnormal S/P ratio in the patients with cirrhosis and portal hypertension was 83.4%. Patients with a higher S/P ratio had a lower risk of developing ascites [odds ratio (OR) = 0.708, 95%CI: 0.508-0.986, P = 0.041] and a higher risk of developing esophageal and gastric varices (OR = 1.483, 95%CI: 1.010-2.175, P = 0.044) and forming collateral circulation (OR = 1.518, 95%CI: 1.033-2.230, P = 0.034). After splenectomy, the portal venous pressure and maximum and mean portal venous flow velocities were reduced, while the flow rate and maximum and minimum flow velocities of the hepatic artery were increased (P portal hypertension, and it can be used as an important marker of splanchnic hemodynamic disturbances.

    Full Text Available Abstract Endovascular stenting has been successfully employed in the management of aortic aneurysms; however, its use in managing peripheral arterial conditions remains questionable. We review the utility of endovascular technique in the management of peripheral arterial conditions like aneurysms, pseudoaneurysms and arterio-venous fistulas in the emergency setting. Though long term data about graft patency rates is not yet available, the endovascular approach appears to be a useful minimally invasive technique in situations where open repair is either difficult or not feasible.

  3. A Case of Pseudoaneurysm of the Internal Carotid Artery Following Endoscopic Endonasal Pituitary Surgery: Endovascular Treatment with Flow-Diverting Stent Implantation

    2017-10-01

    Full Text Available Internal carotid artery (ICA pseudoaneurysm is a rare complication of endoscopic endonasal surgery occurring in 0.4–1.1% of cases. Pseudoaneurysms can subsequently result in other complications, such as subarachnoid hemorrhage, epistaxis, and caroticocavernous fistula with resultant death or permanent neurologic deficit. In this case, we illustrate endovascular treatment with a flow-diverting stent for an ICA pseudoaneurysm after endoscopic endonasal surgery for a pituitary adenoma in a 56-year-old male. Surgery was complicated by excessive intraoperative bleeding and emergent CT angiography confirmed an iatrogenic pseudoaneurysm on the anteromedial surface of the ICA. The pseudoaneurysm was treated endovascularly with flow-diverting stent implantation only. Follow-up CT angiography after three months demonstrated occlusion of the pseudoaneurysm.

    Objective: To investigate the DSA manifestations of the involvement of splenic artery in supplying blood to hepatomas and to assess the therapeutic value of super-selective interventional embolization. Methods: During the period of March 2005-June 2008, 897 patients with hepatoma underwent angiography and the involvement of splenic artery in the blood supply of hepatoma was confirmed in 7 cases. Splenic arteriography was performed by means of super-selective catheterization with 5 F Yashiro catheter together with 3 F SP catheter. The splenic arteries which supplied blood to hepatomas were embolized with hyper-liquid iodized-oil emulsion mixed with chemotherapy drug, which was followed by the injection of sufficient gelatin sponge or ethanol. The clinical results were analyzed. Results: Splenic arteriography revealed that the splenic artery was the main supplying vessel of the hepatoma in two cases, and was not the main supplying vessel of the hepatoma in five cases. The splenic supplying vessels were completely embolized in all 7 cases. After the procedure, AFP level was decreased over 50%, and in two patients it dropped to normal. CT checkup 4-6 weeks after the surgery revealed that the diameter of tumor decreased to 2.5 - 4.6 cm. Conclusion: The involvement of splenic artery in supplying blood to hepatomas is not common. Super-selective catheterization and sufficient embolization of the splenic supplying vessels are very important for improving the interventional effectiveness. (authors)

  5. Misdiagnosis and management of iatrogenic pseudoaneurysm of vertebral artery after Harms technique of C1-C2 fixation

    2012-12-01

    Full Text Available 【Abstract】 Harms technique of C1-C2 fixation for atlantoaxial complex becomes more popular due to good fusion rate and low vertebral artery injury (VAI rate. But considering the unique and variable anatomy of atlanto-axial complex, iatrogenic VAI will result in catastrophic con-sequences and provides particular surgical challenges for surgeons. To our knowledge, comparing with iatrogenic VAI in the screw hole, iatrogenic VAI in the “open space” is much rarer during the Harms technique of C1-C2 fixation. In this article, we present a case of iatrogenic vertebral artery pseudoaneurysm after Harms technique of posterior C1-C2 fixation. This case of iatrogenic VAI effectively treated by endovascular coil occlusion and external local compression was initially misdiagnosed as VAI by pedicle screw perforation. It can be concluded that intraoperative or post-operative computed angiography is very helpful to diag-nose the exact site of VAI and the combination of endovascular coil occlusion as well as external local com-pression can further prevent bleeding and abnormal verte-bral artery flow in the pseudoaneurysm. However, patients treated require further follow-up to confirm that there is no recurrence of the pseudoaneurysm. Key words: Vertebral artery; Aneurysm, false; Endovascular procedures

    Iatrogenic pseudoaneurysm formation is an uncommon but potentially serious complication of cardiac catheterization. This case report describes diagnosis and treatment of a large left external iliac artery pseudoaneurysm in a 3-month-old boy following cardiac catheterization and aortic balloon dilatation for aortic coarctation. A 4-cm pulsatile mass in the left hemipelvis was discovered on MRI performed 6 weeks later for possible tethered spinal cord. Sonography and angiography showed a large pseudoaneurysm of the left external iliac artery just distal to the iliac bifurcation with no flow in the external iliac artery distal to the pseudoaneurysm. Percutaneous US-guided thrombin injection was performed twice, with partial recanalization after each treatment. The residual portion of the pseudoaneurysm was then successfully embolized with percutaneous coils deployed under US and fluoroscopic guidance.

    Full Text Available Background: Bleeding from esophageal varices is one of the most common causes of serious gastrointestinal haemorrhage in children. We analysed our experience with the use of splenic artery embolisation and variceal sclerotherapy for bleeding oesophageal varices. Patients and Methods: Records of all patients treated for bleeding oesophageal varices caused by portal hypertension from 1998 to 2004 were retrospectively analysed. Patients were followed up for five years. Results: Out of 25 patients treated, ten belonged to sclerotherapy (group A, eight to combined sclerotherapy and embolisation (group B, and seven to only embolisation (group C. The patients were selected randomly, only two patients who had active bleed recently were directly sclerosed. The splenic artery was embolised at the hilum using steel coils in 15 patients with portal hypertension and hypersplenism. Follow-up findings showed decrease in splenic mass, varices, and hyperdynamic flow. Conclusion: In spite of few patients and a short period of follow-up, our results pointed out that a serious consideration should be given to this procedure, as it slowed the sequel of portal hypertension and the complications associated with it. Patients who were embolised and followed up for five years had lesser rebleeds and complications than sclerotherapy patients.

    The case of a 30-year-old woman with a post-traumatic pseudoaneurysm of the superior mesenteric artery and associated celiac axis occlusion is presented. The patient was successfully treated with celiac artery recanalization and placement of a covered stent within the superior mesenteric artery. Follow-up at 3, 6, and 12 months and 3 years demonstrated patency of the covered stent and continued exclusion of the aneurysm. Although the long-term success of this procedure is unknown this management option should be considered where facilities are available, to reduce the increased morbidity associated with open surgical procedure

    Objective To investigate the clinical efficacy of individual endovascular management for the treatment of different traumatic pseudoaneurysms presenting as intractable epistaxis. Materials and Methods For 14 consecutive patients with traumatic pseudoaneurysm presenting as refractory epistaxes, 15 endovascular procedures were performed. Digital subtraction angiography revealed that the pseudoaneurysms originated from the internal maxillary artery in eight patients; and all were treated with occlusion of the feeding artery. In six cases, they originated from the internal carotid artery (ICA); out of which, two were managed with detachable balloons, two with covered stents, one by means of cavity embolization, and the remaining one with parent artery occlusion. All of these cases were followed up clinically from six to 18 months, with a mean follow up time of ten months; moreover, three cases were also followed with angiography. Results Complete cessation of bleeding was achieved in all the 15 instances (100%) immediately after the endovascular therapies. Of the six patients who suffered from ICA pseudoaneurysms, one presented with a permanent stroke and one had an episode of rebleeding requiring intervention. Conclusion In patients presenting with a history of craniocerebral trauma, traumatic pseudoaneurysm must be considered as a differential diagnosis. Individual endovascular treatment is a relatively safe, plausible, and reliable means of managing traumatic pseudoaneurysms. PMID:21076585

    To evaluate the efficacy and benefits of transcatheter arterial embolization (TAE) in patients with blunt splenic injury after blunt abdominal trauma. We retrospectively analyzed the results of transcatheter arterial embolization in 23 patients who suffered splenic injury after blunt abdominal trauma. Fourteen of the patients were male, and 9 were female; 13 were adults, and 10 were children. Transcatheter arterial embolization was performed in patients with hypotension, tachycardia, evidence of hemodynamic instability due, for example, to low levels of Hgb and Hct, or those who needed fluid therapy or blood transfusion. After embolization the patients' progress was monitored by CT scanning, abdominal sonography, or 99m Tc-sulfur colloid scintigraphy. The degree of splenic injury was classified according to the system devised by Mirvis et al.; nine cases were CT grade III, and 14 were grade IV. After demonstrating angiographically the site of contrast leakage, embolization was performed; for this, a coil only was used in 16 cases, gelfoam only in four, and both coil and gelfoam in three. There were three sites of vascular embolization: 16 procedures were performed in the proximal part of the main trunk of the splenic artery, four in a superselected branch of this same artery, and three in both the splenic artery and one of its superselected branches. Of the 23 cases, 18 recovered without splenectomy after embolization, three adult patients died from coexisting conditions (spinal or cerebral injuries, liver cirrhosis, or pelvic bone fracture) or complications (acute renal failure or disseminated intravascular coagulation). Due to co-existing pancreatic and mesenteric vessel injury, two of the adult patients who underwent TAE also underwent delayed surgery; intraoperatively, there was no evidence of splenic rebleeding. In all patients who did not undergo surgery, follow-up observation revealed a decreased volume of hemoperitoneum, increased uptake of radionuclide in

  12. A case of gastrointestinal bleeding due to right hepatic artery pseudoaneurysm following total remnant pancreatectomy: A case report

    Directory of Open Access Journals (Sweden)

    Atsushi Fujio

    Full Text Available Introduction: Pseudoaneurysm is a serious complication after pancreatic surgery, which mainly depends on the presence of a preceding pancreatic fistula. Postpancreatectomy hemorrhage following total pancreatectomy is a rare complication due to the absence of a pancreatic fistula. Here we report an unusual case of massive gastrointestinal bleeding due to right hepatic artery (RHA pseudoaneurysm following total remnant pancreatectomy. Presentation of case: A 75-year-old man was diagnosed with intraductal papillary mucinous carcinoma recurrence following distal pancreatectomy and underwent total remnant pancreatectomy. After discharge, he was readmitted to our hospital with melena because of the diagnosis of gastrointestinal bleeding. Gastrointestinal endoscopy was performed to detect the origin of bleeding, but an obvious bleeding point could not be detected. Abdominal computed tomography demonstrated an expansive growth, which indicated RHA pseudoaneurysm. Emergency angiography revealed gastrointestinal bleeding into the jejunum from the ruptured RHA pseudoaneurysm. Transcatheter arterial embolization was performed; subsequently, bleeding was successfully stopped for a short duration. Because of improvements in his general condition, the patient was discharged. Discussion: To date, very few cases have described postpancreatectomy hemorrhage following total remnant pancreatectomy. We suspect that the aneurysm ruptured into the jejunum, possibly because of the scarring and inflammation associated with his two complex surgeries. Conclusion: Pseudoaneurysm should be considered when the fragility of blood vessels is suspected, despite no history of anastomotic leak and intra-abdominal abscess. Our case also highlighted that detecting gastrointestinal bleeding is necessary to recognize sentinel bleeding if the origin of bleeding is undetectable.

    The authors retrospectively studied the records and Tc-99m sulfur colloid (TSC) splenic artery and vein resection for donation to HLA-compatible relatives. Of 37 patients with postoperative TSC studies, four had no postoperative splenic abnormalities. Nineteen of the abnormal TSC studies were followed with TSC studies 2 weeks to 14 months later; three showed no change, seven showed improvements,and ten became normal. One patient required splenectomy 2 days after pancreatectomy for splenic infarction; her TSC study showed no uptake. These data suggest that the spleen usually survives splenic artery and vein resection. Absent splenic TSC uptake raises the possibility of splenic infarction but usually improves

    Full Text Available The radial artery access has gained popularity as a method of diagnostic coronary catheterization compared to femoral artery puncture in terms of vascular complications and early ambulation. However, very rare complication like radial artery pseudoaneurysm may occur following cardiac catheterization which may give rise to serious consequences. Here, we report a patient with radial pseudoaneurysm following diagnostic coronary angiography. Adequate and correct methodology of compression of radial artery following puncture for maintaining hemostasis is the key to prevention.DOI: http://dx.doi.org/10.3126/jcmsn.v10i3.12776 Journal of College of Medical Sciences-Nepal, 2014, Vol-10, No-3, 48-50

    Purpose: Our purpose was to evaluate iatrogenic renal pseudoaneurysms, endovascular treatment, and outcomes. Methods: This retrospective study (2003-2011) reported the technical and clinical outcomes of endovascular therapy for renal pseudoaneurysms in eight patients (mean age, 46 (range 24-68) years). Renal parenchymal loss evaluation was based on digital subtraction angiography and computed tomography. Results: We identified eight iatrogenic renal pseudoaneurysm patients with symptoms of hematuria, pain, and hematoma after renal biopsy (n = 3), surgery (n = 3), percutaneous nephrolithotomy (n = 1), and endoscopic shock-wave lithotripsy (n = 1). In six patients, the pseudoaneurysms were small-sized (<20 mm) and peripherally located and were treated solely with coil embolization (n = 5). In one patient, coil embolization was preceded by embolization with 500-700 micron embospheres to control active bleeding. The remaining two patients had large-sized ({>=}50 mm), centrally located renal pseudoaneurysms treated with thrombin {+-} coils. Technical success with immediate bleeding cessation was achieved in all patients. There were no procedure-related deaths or complications (mean follow-up, 23.5 (range, 1-67) months). Conclusions: Treatment of renal pseudoaneurysms using endovascular approach is a relatively safe and viable option regardless of location (central or peripheral) and size of the lesions with minimal renal parenchymal sacrifice.

    Thrombin injection has been proven to be successful in postcatheterization pseudoaneurysms. However, there are only a few reports on the treatment of pseudoaneurysms of the trunk. We report our first experiences using a percutaneous as well as an endovascular access. Eight iatrogenic pseudoaneurysms of the trunk (aorta, n = 4; pulmonary artery, n = 1; gastroduodenal artery, n = 1; left gastric artery, n = 1, renal artery, n = 1) were treated either percutaneously using CT guidance (n = 3) or via an endovascular access (n = 5). Noninvasive control angiograms were performed at day 1 and weeks 1 and 3 by either CT or MR angiography. The total volume of the pseudoaneurysms was 31.2 +/- 23.1 ml on average, with a mean volume of the perfused aneurysmal lumen of 12.9 +/- 7.2 ml. The maximum diameter was 4.1 +/- 1.39 cm on average. In each case, the aneurysmal neck was not wider than 2 mm. One pseudoaneurysm occluded spontaneously following selective catheterization. The remaining pseudoaneurysms were successfully treated by injection of 765 +/- 438.1 IU thrombin. In one individual, a nontarget embolization occurred, as well as an intervention-associated rupture of a pseudoaneurysm. High-grade stenoses of the donor artery were found in a different case. Only once was the endoluminal access converted to a percutaneous one. Thrombin injection might be a future first-line treatment of vascular lesions such as pseudoaneurysms of the trunk. In our experience both percutanous and endoluminal access are technically feasible and safe. However, further experiences are mandatory, especially concerning the question of dosage and long-term results.

    We present the history of a woman suffering from an extensive gastrointestinal bleeding due to liver cirrhosis and chronic pancreatitis. Selective angiogram of the celiac artery revealed a pseudoaneurysm of the gastroduodenal artery caused by inflammatory wall penetration. The life-threatening hemorrhage was completely stopped by embolization with three stainless steel coils after microcatheter engagement of the gastroduodenal artery. The particularity of this case is the restricted embolization of the aneurysm vessel segment, so the collateral circulation of the gastroduodenal and pancreaticoduodenal artery could be preserved.

    We studied the changes in proximal embolization of the splenic artery to the intraparenchymal blood flow with Doppler ultrasound. Seventeen trauma patients with spleen injury OIS grade 2-5 underwent embolization of the splenic artery. Peak-systolic velocity (PSV) and end-diastolic velocity (EDV) were measured in intrasplenic arteries initially 1 day after embolization, at early follow-up after 7 days, at intermediate follow-up after 10 weeks, and at late follow-up after 10 months. Resistance index (RI), systolic/diastolic ratio (S/D ratio), acceleration (AC), and acceleration time (AT) were calculated. The results were compared to values from 17 volunteers. RI increased from 0.39 initially to 0.49 (P = 0.002) at intermediate and to 0.52 (P 2 initially to 1.89 m/s 2 at late follow-up (P = 0.01). AC at late follow-up was not different from reference group (2.33 m/s 2 ). In conclusion, Doppler ultrasound is a useful tool in the evaluation of improvable intraparenchymal blood flow over time after central splenic artery embolization. (orig.)

    Iatrogenic injury of a lumbar artery is very rare and mostly causes retroperitoneal hemorrhage. We report a case of a lumbar artery pseudoaneurysm and a concomitant arteriovenous fistula complicating laparoscopic splenectomy and provoking renal colic-like flank pain due to mass effect on the left ureter. Definitive treatment of both vascular lesions was obtained after percutaneous transcatheter embolization of several lumbar arteries. Control computed tomography scan 3 months after embolization showed almost complete resorption of the retroperitoneal hematoma. (orig.)

    Splenic artery aneurysm is rare and its diagnosis is challenging due to the nonspecific nature of the clinical presentation. We report a case of a splenic artery aneurysm in which the patient presented with chronic dyspepsia and multiple episodes of minor intragastric bleeding. A 60-year-old, previously healthy Sri Lankan man presented with four episodes of hematemesis and severe dyspeptic symptoms over a period of 6 months. The results of two initial upper gastrointestinal endoscopies and an abdominal ultrasound scan were unremarkable. A third upper gastrointestinal endoscopy detected a pulsatile bulge at the posterior wall of the gastric antrum. A contrast-enhanced computed tomogram of his abdomen detected a splenic artery aneurysm measuring 3 × 3 × 2.5 cm. While awaiting routine surgery, he developed a torrential upper gastrointestinal bleeding and shock, leading to emergency laparotomy. Splenectomy and en bloc resection of the aneurysm with the posterior stomach wall were performed. Histology revealed evidence for a true aneurysm without overt, acute, or chronic inflammation of the surrounding gastric mucosa. He became completely asymptomatic 2 weeks after the surgery. Splenic artery aneurysms can result in recurrent upper gastrointestinal bleeding. The possibility of impending catastrophic bleeding should be remembered when managing patients with splenic artery aneurysms after a minor bleeding. Negative endoscopy and ultrasonography should require contrast-enhanced computed tomography to look for the cause of recurrent upper gastrointestinal bleeding.

    Thrombin injection has been proven to be successful in postcatheterization pseudoaneurysms. However, there are only a few reports on the treatment of pseudoaneurysms of the trunk. We report our first experiences using a percutaneous as well as an endovascular access. Eight iatrogenic pseudoaneurysms of the trunk (aorta, n = 4; pulmonary artery, n = 1; gastroduodenal artery, n = 1; left gastric artery, n = 1, renal artery, n = 1) were treated either percutaneously using CT guidance (n = 3) or via an endovascular access (n = 5). Noninvasive control angiograms were performed at day 1 and weeks 1 and 3 by either CT or MR angiography. The total volume of the pseudoaneurysms was 31.2 ± 23.1 ml on average, with a mean volume of the perfused aneurysmal lumen of 12.9 ± 7.2 ml. The maximum diameter was 4.1 ± 1.39 cm on average. In each case, the aneurysmal neck was not wider than 2 mm. One pseudoaneurysm occluded spontaneously following selective catheterization. The remaining pseudoaneurysms were successfully treated by injection of 765 ± 438.1 IU thrombin. In one individual, a nontarget embolization occurred, as well as an intervention-associated rupture of a pseudoaneurysm. High-grade stenoses of the donor artery were found in a different case. Only once was the endoluminal access converted to a percutaneous one. Thrombin injection might be a future first-line treatment of vascular lesions such as pseudoaneurysms of the trunk. In our experience both percutanous and endoluminal access are technically feasible and safe. However, further experiences are mandatory, especially concerning the question of dosage and long-term results

    A pseudoaneurysm or false aneurysm of the brachial artery is an uncommon occurrence in patients receiving hemodialysis with arteriovenous fistula (AVF). We describe the case of a 76-year-old woman presenting with a large, tender, pulsatile mass in the right antecubital region 10 cm from the AVF. B-mode ultrasound examination revealed a saccular hematoma. Color doppler showed a recirculation movement of blood, creating a two colors image called "Korean flag". The patient was transferred to the surgical unit where she first underwent ultrasound-guided compression and then surgical repair of the pseudoaneurysm. Two weeks after surgery the AVF was used again as an access for hemodialysis. Differentiating between a false and a true aneurysm based on ultrasound is not always straightforward. Doppler ultrasound findings can be decisive for the early diagnosis of a pseudoaneurysm to ensure proper treatment planning given the dangerous complications of ruptures. Treatment options include: compression, percutaneous thrombin injection, endovascular exclusion with covered stents, aneurysmectomy and surgical repair.

    Objective: To discuss the effects and the complications of partial splenic artery embolization with gelatin sponge or with lipiodol for hypersplenism, to provide scientific information helpful for the selection of embolization materials in clinical practice. Methods: Partial splenic artery embolization with gelatin sponge was performed in forty patients with hypersplenism due to cirrhosis (gelatin sponge group) and partial splenic artery embolization with lipiodol was carried out in another thirty-nine patients (lipiodol group). The clinical data were retrospectively analyzed. The laboratory studies, complications and recurrence were observed and compared between two groups. Results: No significant difference in the reduction of splenic size, in the hemoglobin levels and in the thrombocyte and leucocyte counts existed between two groups (P > 0.05). However, the platelet count in lipiodol group was obviously decreased three months after the treatment. The occurrence of complications in gelatin sponge group was much higher than that in lipiodol group (P < 0.05). The toxic reaction of the liver and gastrointestinal tract in lipiodol group was significantly slighter than that in gelatin sponge group. Conclusion: Partial splenic artery embolization with lipiodol should be employed for the treatment of hypersplenism when the patient is elder and the disease is accompanied by poor liver function, massive ascites, severe dysfunction of blood coagulation and serious portal hypertension.

    Introduction: Nonoperative management (NOM) has become the treatment of choice for hemodynamically stable patients with blunt splenic injury. Results of outcome after NOM are predominantly based on large-volume studies from level 1 trauma centers in the United States. This study was designed to assess the results of NOM in a relatively low-volume Dutch level 1 trauma center. Methods: An analysis of a prospective trauma registry was performed for a 6-year period before (period 1) and after the introduction and implementation of splenic artery embolization (SAE) (period 2). Primary outcome was the failure rate of initial treatment. Results: A total of 151 patients were reviewed. An increased use of SAE and a reduction of splenic operations during the second period was observed. Compared with period 1, the failure rate after observation in period 2 decreased from 25% to 10%. The failure rate after SAE in period 2 was 18%. The splenic salvage rate (SSR) after observation increased from 79% in the first period to 100% in the second period. During the second period, all patients with failure after observation were successfully treated with SAE. The SSR after SAE in periods 1 and 2 was respectively 100% and 86%. Conclusions: SAE of patients with blunt splenic injuries is associated with a reduction in splenic operations. The failure and splenic salvage rates in this current study were comparable with the results from large-volume studies of level 1 trauma centers. Nonoperative management also is feasible in a relatively low-volume level 1 trauma center outside the United States.

    Mycotic false aneurysm caused by local arterial injury from attempted intravenous injections in drug addicts remains a challenging clinical problem. The continued increase in drug abuse has resulted in an increased incidence of this problem, particularly in high-volume urban centres. In the drug-abusing population, mycotic arterial pseudoaneurysms most often occur because of missed venous injection and are typically seen in the groin, axilla, and antecubital fossa. Mycotic aneurysms may lead to life-threatening haemorrhage, limb loss, sepsis, and even death. Any soft-tissue swelling in the vicinity of a major artery in an intravenous drug abuser should be suspected of being a false aneurysm until proven otherwise and should prompt immediate referral to a vascular surgeon for investigation and management. We report a case of rupturing mycotic pseudoaneurysm of the left common femoral artery treated by surgical resection followed by vessel reconstruction with autologous material. Unfortunately, at the time of discharge a sudden leakage from the vein graft anastomosis occurred, with subsequent massive bleeding, and required emergent endovascular covered stenting. To the best of our knowledge, this is the first reported case of femoral artery bleeding in a drug abuser treated by stent graft placement.

    Pseudoaneurysm of the infrarenal aorta due to Behcet s disease is very rare. We report a case of pseudoaneurysm associated with Behcet s disease in a 17-year-old boy with a recurrent right ventricular thrombus successfully treated with revascularization using arterial homograft patch. Echocardiography examination revealed a right ventricular mass, thought to be a thrombus in an unusual location. Postoperatively, the findings of the pathologic examination confirmed the mass as a thrombus. When the patient was subsequently re-admitted to the emergency unit with complaints of severe abdominal pain, fever, fatigue, sinus tachycardia, and a pulsating and tender abdominal mass, a right ventricular thrombus and a large pseudoaneurysm of the abdominal aorta were found on echocardiography and angiography. The patient underwent resection of the aortic aneurysm and aortoplasty, using arterial homograft patch, and received immunosuppressive and anticoagulation therapy. The thrombus of the right ventricle disappeared 4 months later. This case indicates that a right ventricular thrombosis in Behcet s disease may be managed by medical therapy. (author)

    Doppler flow indices (DFIs), such as the resistive index (RI) and the pulsatility index (PI), are commonly used to characterize blood flow. Parenchymal infiltration of an organ and administration of sedative and anaesthetic drugs can affect DFIs by altering resistance to blood flow. In this prospective study, the effect on DFIs of two sedative protocols (acepromazine or dexmedetomidine, each combined with butorphanol) and the presence or absence of hepatic and/or splenic disease, was investigated in the splenic arteries of 75 dogs. The RI and PI in splenic arteries of dogs sedated with dexmedetomidine and butorphanol were lower than those of dogs sedated with acepromazine and butorphanol. PI in splenic arteries was higher in animals with hepatosplenic disease than in healthy animals. Receiver Operating Characteristic (ROC) curves suggested that PI measured in canine splenic arteries could be useful in predicting the presence of hepatosplenic disease in the absence of other abdominal disease.

    ObjectiveThis retrospective study reports our experience using splenic arterial particle embolization and coil embolization for the treatment of sinistral portal hypertension (SPH) in patients with and without gastric bleeding.MethodsFrom August 2009 to May 2012, 14 patients with SPH due to pancreatic disease were diagnosed and treated with splenic arterial embolization. Two different embolization strategies were applied; either combined distal splenic bed particle embolization and proximal splenic artery coil embolization in the same procedure for acute hemorrhage (1-step) or interval staged distal embolization and proximal embolization in the stable patient (2-step). The patients were clinically followed.ResultsIn 14 patients, splenic arterial embolization was successful. The one-step method was performed in three patients suffering from massive gastric bleeding, and the bleeding was relieved after embolization. The two-step method was used in 11 patients, who had chronic gastric variceal bleeding or gastric varices only. The gastric varices disappeared in the enhanced CT scan and the patients had no gastric bleeding during follow-up.ConclusionsSplenic arterial embolization, particularly the two-step method, proved feasible and effective for the treatment of SPH patients with gastric varices or gastric variceal bleeding.

    A 74-year-old man presented with a ruptured infected anastomotic femoral pseudoaneurysm. Due to severe medical comorbidities he was considered unsuitable for conventional surgical management and underwent an emergency endovascular repair with a balloon-expandable covered stent. The pseudoaneurysm was excluded successfully and the patient had an uneventful postoperative recovery with long-term suppressive antimicrobials. He remained well for 10 months after the procedure with no signs of recurrent local or systemic infection and finally died from an acute myocardial infarction. To our knowledge, emergency endovascular treatment of a free ruptured bleeding femoral artery pseudoaneurysm has not been documented before in the English literature. This case illustrates that endovascular therapy may be a safe and efficient alternative in the emergent management of ruptured infected anastomotic femoral artery pseudoaneurysms when traditional open surgery is contraindicated

    Although n-butyl-2-cyanoacrylate (NBCA) has been used as an effective liquid embolization material, its indication for pseudoaneurysms has seemingly been limited because of the technical difficulties of using NBCA, such as reflux to the parent artery and causing significant infarction. Thus, considerable skill in using NBCA or a device to control blood flow during its polymerization is required to achieve embolization without severe complications. We report our new technique for controlling blood flow using diluted epinephrine in transcatheter arterial NBCA embolization of five pseudoaneurysms in four cases secondary to hemosuccus pancreaticus.

    Objective: To discuss the method, mid-long term clinical therapeutic effect and safety of coil embolization in treating patients with hepatic arterial pseudoaneurysm (HAPA). Methods: Seven patients with repeatedly massive hemorrhage of gastrointestinal tract were undertaken DSA of celiac arteries and hepatic arteries and embolization of the feeding artery by coils or microcoils after correct diagnosis. All cases underwent follow-up from 6 to 60 months(mean 38). Results: The blood loss before angiography was ranged from 1200 to 4 000 (mean 2 385) ml. There were 3 cases with normal hepatic function and 4 with hepatic dysfunction including ALT increase in 2 and obstructive jaundice in another. Digital substraction angiography (DSA) clearly showed the location, shape and feeding arteries of HAPA. There were 2 types of HAPA namely intrahepatic (n=3)and extrahepatic (n=4), adding one case with arteriovenous fistula (AVF). Embolization was successful in all cases by coils (n=13) or microcoils (n=12). No recurrence and any definite clinical complication occurred during follow-up. Conclusion: Coil embolization in treating HAPA is safe and effective with mid-long term positive clinical therapeutic efficiency without severe complications. (authors)

    To determine if the addition of an arterial phase abdominal computed tomography (CT) improves clinical outcomes in patients with blunt splenic injuries. Retrospective review of patients who underwent CT of the abdomen revealing splenic injuries. Clinical management in these patients was determined. Fifty-one of three thousand five hundred twenty-five patients had splenic injuries. Twenty-five patients underwent nonsurgical management, and 3 failed. The theoretical additional arterial phase resulted in a 62% increase in mean effective dose compared to the portal venous phase alone. Routine use of arterial phase CT in blunt trauma patients may not be warranted as there is minimal improvement in outcomes. Copyright © 2015 Elsevier Inc. All rights reserved.

    Internal carotid artery (ICA) lesions in the parapharyngeal space (a dissection and a pseudoaneurysm) may present as isolated lower cranial nerves (IX, X, XI, and XII) palsy (Collet-Sicard syndrome). Some arteriopathies such as fibromuscular dysplasia and tortuosity make a vessel predisposed to dissection. Extreme vessel tortuosity makes the treatment by a stent graft impossible. Two Silk stents were used in a 46 year-old man with left lower cranial nerves (IX-XII) palsy for the treatment of left ICA spontaneous dissection with pseudoaneurysm. A follow-up angiogram 5 months later confirmed pseudoaneurysm thrombosis and patency of the left ICA. The patient recovered completely from the deficits.

    Complications during the placement of a central venous catheter, via the right internal jugular vein puncture include local hematoma, hemothorax, pneumothorax, central vein thrombosis, and hemopericardium. Iatrogenic right internal jugular vein-right subclavian artery fistula with the formation of right subclavian artery pseudoaneurysms is an extremely rare complication in patients undergoing a central vein puncture. We report the case of a patient who developed a local hematoma at the vein puncture site and dyspnea due to a right internal jugular vein-subclavian artery fistula and a right subclavian artery pseudoaneurysm at the mediastinum after puncture of right internal jugular vein. The patient was successfully treated by embolization using microcoils

    To determine the risk factors, clinical characteristics, surgical management and outcome of pseudoaneurysm secondary to iatrogenic or traumatic vascular injury. This was a cross-sectional study being performed in department of cardiovascular and thoracic surgery skims soura during a 4-year period. We included all the patients referring to our center with primary diagnosis of pseudoaneurysm. The pseudoaneurysm was diagnosed with angiography and color Doppler sonography. The clinical and demographic characteristics were recorded and the risk factors were identified accordingly. Patients with small swelling (less than 5-cm) and without any complication were managed conservatively. They were followed for progression and development of complications in relation to swelling. Others underwent surgical repair and excision. The outcome of the patients was also recorded. Overall we included 20 patients with pseudoaneurysm. The mean age of the patients was 42.1±0.6 years. Among them there were 11 (55%) men and 9 (45%) women. Nine (45%) patients with end stage renal disease developed pseudoaneurysm after inadvertent femoral artery puncture for hemodialysis; two patients after interventional cardiology procedure; one after femoral embolectomy; one developed after fire arm splinter injury and one formed femoral artery related pseudoaneurysm after drainage of right inguinal abscess. The most common site of pseudoaneurysm was femoral artery followed by brachial artery. Overall surgical intervention was performed in 17 (85%) patients and 3 (15%) were managed conservatively. End stage renal disease is a major risk factor for pseudoaneurysm formation. Coagulopathy, either therapeutic or pathological is also an important risk factor. Patients with these risk factors need cannulation of venous structures for hemodialysis under ultrasound guide to prevent inadvertent arterial injury. Patients with end stage renal disease who sustain inadvertent arterial puncture during cannulation for

    We describe an extremely rare cardiac lipoma, with electrocardiographic changes in ST segments and T waves, suggesting ischemic heart disease. The abnormal electrocardiogram was identified during a routine physical examination of an asymptomatic 57-year-old man. Coronary angiography showed no stenotic or occlusive lesions in the coronary arteries except that the left anterior descending artery followed a winding course in the apical region. Left ventriculography revealed a pseudoaneurysm-like mass around the apical portion. Computed tomography and magnetic resonance imaging revealed a cardiac lipoma that communicated with the left ventricle and resembled a pseudoaneurysm. After complete resection of the lipoma and left ventricle patch plasty, the postoperative course was uneventful. Histologically, the tumor was an intramyocardiac lipoma with no evidence of malignancy. To our knowledge, we are the first to describe an intramyocardiac lipoma resembling a left ventricle pseudoaneurysm.

    Full Text Available Uterine artery embolization is the most common treatment for uterine vascular abnormalities. Herein, we report the successful use of dilation and evacuation as a treatment for uterine artery pseudoaneurysm. A 36-year-old woman complained of vaginal bleeding after an uncomplicated vaginal delivery. Ultrasonography showed a 12.8-mm anechoic area inside the uterus. Color Doppler revealed a to-and-fro sign, indicating an arteriovenous malformation. A blood test showed a low level of human chorionic gonadotropin. Therefore, a diagnosis of early uterine artery pseudoaneurysm following spontaneous delivery was suspected. Under monitoring with transabdominal color Doppler sonography, intrauterine balloon tamponade induced complete disappearance of abnormal blood flow. With bleeding determined to be under control with balloon tamponade, dilation and evacuation was performed. The patient had a favorable postoperative course.

    Full Text Available We report the first case of blunt splenic rupture in a child with situs inversus totalis treated with transcatheter arterial embolization (TAE. A 12-year-old girl fell roughly 4 feet onto the pavement while riding her bicycle. Contrast-enhanced computed tomography revealed situs inversus totalis, a massive hemorrhage in the abdominal cavity, and a ruptured spleen with extravasation. Arteriography showed that the internal organs were located opposite their normal positioning. TAE was carried out with gelfoam and a micro coils at the branch of the upper lobe of the splenic artery. TAE is effective for blunt splenic injury with extravasation in a child with situs inversus. In TAE, there is no technical difference about situs inversus excepted mirror image of abdominal vascular formation.

  7. Complete Remission of Pancreatic Pseudoaneurysm Rupture with Arterial Embolization in a Patient with Poor Risk for Surgery: A Case Report

    Full Text Available Pancreatic pseudoaneurysm is a rare vascular complication of chronic pancreatitis resulting from erosion of the pancreatic or peripancreatic artery into a pseudocyst that is identified as a pulsating vascular malformation which may lead to lethal complications if left untreated. Many publications in the literature consider angiography as the first step in the management of pancreatic pseudoaneurysm to stabilize the patient’s critical condition; it should be followed by surgical intervention as the definite treatment. We report a rare case of pancreatic pseudoaneurysm rupture with hemodynamic embarrassment in a critical patient with multiple comorbid conditions and poor risk for surgery who responded dramatically to angiographic management as a single therapeutic modality without further surgical intervention. The results observed in our patient suggest that pancreatic pseudoaneurysm may be successfully managed with angiography only and that not all cases require surgical intervention. This is particularly relevant in critically ill patients in whom surgical intervention would be unfeasible.

    To determine whether the addition of arterial phase computed tomography (CT) to the standard combination of portal venous and delayed phase imaging increases sensitivity in the diagnosis of active hemorrhage and/or contained vascular injuries in patients with splenic trauma. The institutional review board approved this HIPAA-compliant retrospective study; the requirement to obtain informed consent was waived. The study included all patients aged 15 years and older who sustained a splenic injury from blunt or penetrating trauma and who underwent CT in the arterial and portal venous phases of image acquisition during a 74-month period (September 2005 to November 2011). CT scans were reviewed by three radiologists, and a consensus interpretation was made to classify the splenic injuries according to the American Association for the Surgery of Trauma splenic injury scale. One radiologist independently recorded the presence of contained vascular injuries or active hemorrhage and the phase or phases at which these lesions were seen. Clinical outcome was assessed by reviewing medical records. The relationship between imaging findings and clinical management was assessed with the Fisher exact test. One hundred forty-seven patients met the inclusion criteria; 32 patients (22%) had active hemorrhage and 22 (15%) had several contained vascular injuries. In 13 of the 22 patients with contained injuries, the vascular lesion was visualized only at the arterial phase of image acquisition; the other nine contained vascular injuries were seen at all phases. Surgery or embolization was performed in 11 of the 22 patients with contained vascular injury. The arterial phase of image acquisition improves detection of traumatic contained splenic vascular injuries and should be considered to optimize detection of splenic injuries in trauma with CT. ©RSNA, 2013.

    A 61-year-old male with a prosthetic St Jude aortic valve size 24 presented with heart failure symptoms and minimal-effort angina. Eleven months earlier, the patient had undergone cardiac surgery because of an aortic root dilatation and bicuspid aortic valve with severe regurgitation secondary to infectious endocarditis by Coxiela burnetii and coronary artery disease in the left circumflex coronary artery. Then, a prosthesis valve and a saphenous bypass graft to the left circumflex coronary artery were placed. The patient was admitted to the Cardiology Department of Hospital Universitario de Canarias, Tenerife, Spain and a transthoracic echocardiography was performed that showed severe paraprosthetic aortic regurgitation and an aortic pseudoaneurysm. The 64-slice multidetector computed tomography confirmed the pseudoaneurysm, originating from the right sinus of Valsalva, with a compression of the native right coronary artery and a normal saphenous bypass graft. On the basis of these findings, we performed surgical treatment with a favorable postoperative evolution. In our case, results from complementary cardiac imaging techniques were crucial for patient management. The multidetector computed tomography allowed for a confident diagnosis of an unusual mechanism of coronary ischemia.

    Objective: To asses the clinical effect of stent-graft in the treatment of pseudoaneurysms. Methods: During the period from March 2008 to June 2011, 86 patients with pseudoaneurysms were admitted to the hospital, of whom stent-graft implantation was carried out in 12. The pseudoaneurysms were located at the thoracic aorta (n=4), abdominal aorta (n=3), common carotid artery (n=3), internal carotid artery (n=1) and right subclavian artery (n=1). All the patient were followed up for 5-43 months. The clinical results were analyzed. Results: The technical success rate for stent delivery was 100%. The pseudoaneurysms was immediately isolated after the procedure in all 12 cases. After endovascular exclusion with stent-graft, no leakage occurred and the blood flow distal to the parent artery was normal. All patients were followed up for a mean period of 23.5 months except one who lost in touch with the authors. One patient with coexisting Behcet's disease died of massive bleeding due to abdominal aortic rupture four months after operation. The other patients were in good clinical condition, and no complications such as stent stenosis, displacement, internal leakage etc. were observed in the follow-up period. Conclusion: The implantation of stent-graft has satisfactory short-term effect in treating pseudoaneurysms, although its long-term efficacy needs to be further observed. (authors)

    An 81-year-oldwoman with advancedgastric cancer was referredto our hospital. Preoperative contrast-enhancedCT revealeda roundcalcification of the splenic hilum with 15mm in diameter as a splenic artery aneurysm. She underwent transcatheter arterial embolization(TAE)for the splenic artery aneurysm. Celiac artery angiography showedcollateral arterial network of the spleen from left gastric artery. Surgery for the gastric cancer was performed1 4 days after TAE. We cut the right gastric andbilateral epigastric arteries. After the left gastric artery clamping, we performedintraoperative indocyanine green(ICG)fluorography. ICG fluorography confirmedthat the bloodflow of the upper thirdof the stomach andspleen were maintained. We safely performed distal gastrectomy, and the postoperative course was uneventful.

    Carotid pseudoaneurysms are a rare consequence of carotid surgery, trauma, and infection. Historically, carotid aneurysms and pseudoaneurysms were treated surgically. However, endovascular techniques have recently become a valid alternative for the treatment of carotid pseudoaneurysms. The case of a 57-year-old male patient with a pseudoaneurysm of the right internal carotid artery is described. The patient came to our unit with a painless and pulsatile mass in the neck, which was growing slowly. Five years earlier, he had undergone surgery on a saccular aneurysm located on the distal extracranial segment of the right internal carotid artery. The pseudoaneurysm was successfully treated with a heparin surface Viabahn stent-graft system (Gore AL, Flagstaff, AZ). Heparin surface stent-grafts can be used for the treatment of carotid lesions and may offer protection against intimal hyperplasia and thrombosis. Further studies are needed to evaluate the long-term results. Copyright © 2010 Annals of Vascular Surgery Inc. Published by Elsevier Inc. All rights reserved.

    We studied the changes in proximal embolization of the splenic artery to the intraparenchymal blood flow with Doppler ultrasound. Seventeen trauma patients with spleen injury OIS grade 2-5 underwent embolization of the splenic artery. Peak-systolic velocity (PSV) and end-diastolic velocity (EDV) were measured in intrasplenic arteries initially 1 day after embolization, at early follow-up after 7 days, at intermediate follow-up after 10 weeks, and at late follow-up after 10 months. Resistance index (RI), systolic/diastolic ratio (S/D ratio), acceleration (AC), and acceleration time (AT) were calculated. The results were compared to values from 17 volunteers. RI increased from 0.39 initially to 0.49 (P = 0.002) at intermediate and to 0.52 (P < 0.001) at late follow-up. S/D ratio increased from 1.68 initially to 1.99 (P = 0.002) and to 2.10 (P < 0.001) at intermediate and late follow-up, respectively. Follow-up results of RI and S/D ratio differed significantly from the reference group. AC increased from 1.06 m/s{sup 2} initially to 1.89 m/s{sup 2} at late follow-up (P = 0.01). AC at late follow-up was not different from reference group (2.33 m/s{sup 2}). In conclusion, Doppler ultrasound is a useful tool in the evaluation of improvable intraparenchymal blood flow over time after central splenic artery embolization. (orig.)

    Background We report a case of bilateral malignant otitis externa complicated with bilateral petrous internal carotid artery pseudoaneurysms and their successful treatment with a flow diverter. Case report A 68-year-old woman with serious complications of type II diabetes mellitus had malignant otitis externa on the right side. She was treated with combined antibiotic therapy and underwent mastoidectomy for mastoiditis. She presented at our hospital with acute hemorrhage from the right external auditory canal. The emergency computed tomography (CT) angiography revealed a multiobulated pseudoaneurysm at the petrous segment of the right internal carotid artery. The pseudoaneurysm was treated with a 5 × 40-mm Surpass flow diverter. Three months later, she developed a malignant external otitis on the left side. As the infection progressed, a left-sided mastoiditis, a brain abscess, and a pseudoaneurysm at the petrous segment of the left internal carotid artery developed. The pseudoaneurysm caused bleeding from the left ear, and was treated with a 5 × 50-mm Surpass flow diverter. No recurrent bleeding was observed. Four months later, a follow-up angiography showed complete occlusion of the pseudoaneurysm on the left side, but a residual aneurysm could be detected on the right side. One year after the first intervention, the follow-up CT and magnetic resonance angiography revealed the complete occlusion of the aneurysms bilaterally. Conclusion The use of a flow diverter appears to be an efficient and safe method to occlude carotid pseudoaneurysms even in an inflammatory milieu.

    2016-04-01

    Full Text Available Selective splenic artery embolization (SSAE is a nonsurgical intervention characterized by the transcatheter occlusion of the splenic artery and/or its branch vessels using metallic coils or other embolic devices. It has been applied for the management of splenic trauma, hypersplenism with portal hypertension, hereditary spherocytosis, thalassemia and splenic hemangioma. We hereby describe a case of a patient affected by idiopathic thrombocytopenic purpura (ITP and warm auto-immune hemolytic anemia (AIHA both resistant to immunosuppressive and biological therapies, not eligible for a surgical intervention because of her critical conditions. She underwent SSAE and achieved a hematologic complete response within a few days without complications. SSAE is a minimally invasive procedure to date not considered a standard option in the management of AIHA and ITP. However, following the progressive improvement of the techniques, its indications have been extended, with a reduction in morbidity and mortality compared to splenectomy in patients with critical clinical conditions. SSAE was a lifesaving therapeutic approach for our patient and it may represent a real alternative for the treatment of resistant AIHA and ITP patients not eligible for splenectomy.

    Full Text Available Pulmonary artery pseudoaneurysm (PAPA, an uncommon complication of pyogenic bacterial and fungal infections and related septic emboli, is associated with high mortality. The pulmonary artery (PA lacks an adventitial wall; therefore, repeated endovascular seeding of the PA with septic emboli creates saccular dilations that are more likely to rupture than systemic arterial aneurysms. The most common clinical presentation of PAPA is massive hemoptysis and resultant worsening hypoxemia. Computed tomography angiography is the preferred diagnostic modality for PAPA; typical imaging patterns include focal outpouchings of contrast adjacent to a branch of the PA following the same contrast density as the PA in all phases of the study. In mycotic PAPAs, multiple synchronous lesions are often seen in segmental and subsegmental PAs due to ongoing embolic phenomena. The recommended approach for a mycotic PAPA is prolonged antimicrobial therapy; for massive hemoptysis, endovascular treatment (e.g., coil embolization, stenting, or embolization of the feeding vessel is preferred. PAPA resection and lobectomy are a last resort, generally reserved for patients with uncontrolled hemoptysis or pleural hemorrhage. We present a case of a 28-year-old woman with necrotizing pneumonia from intravenous drug use who ultimately died from massive hemoptysis and shock after a ruptured PAPA.

    2010-01-01

    We present the case of a late superficial femoral artery stent disconnection causing an asymptomatic pseudoaneurysm successfully treated with a stent-graft. A 67-year-old female was referred to our department for evaluation of claudication of the left lower limb and was diagnosed to have a total occlusion of the superficial femoral artery. Three nitinol stents were used to revascularize this artery. At 48 months, duplex-ultrasonography control revealed the presence of a 45-mm saccular femoral dilatation; X-rays and CT angiography showed fractures of the proximal stents and the presence of a pseudoaneurysm at the site of the distal stents disconnection. The pseudoaneurysm was excluded using two stent-grafts. We conclude that patients and surgeons should be aware of structural complications with all stents. Rigorous follow-up controls should be mandatory. Endovascular repair proved to be feasible and durable to manage a previous endovascular procedure.

    Tumors of the neck of the pancreas may involve the superior mesenteric and portal veins as well as the termination of the splenic vein. This presents a difficult problem since the pancreas cannot be transected through the neck as is standard in a Whipple procedure. Here, we present our method of resecting such tumors, which we term "Whipple at the Splenic Artery (WATSA)". The superior mesenteric and portal veins are isolated below and above the pancreas, respectively. The pancreas and splenic vein are divided just to the right of the point that the splenic artery contacts the superior border of the pancreas. This plane of transection is approximately 2 cm to the left of the pancreatic neck and away from the tumor. The superior mesenteric artery is cleared from the left side of the patient. With the specimen remaining attached only by the superior mesenteric and portal veins, these structures are clamped and divided. Reconstruction is performed with or without a superficial femoral vein graft. The splenic vein is not reconstructed. Ten cases have been performed to date without mortality. We have previously shown that the pattern of venous collateral development following occlusion of the termination of the splenic vein in the manner described is not similar to that of cases of sinistral (left sided) portal hypertension. Whipple at the splenic artery (WATSA) is a safe method for resection of tumors of the neck of the pancreas with vein involvement. It should be performed in high-volume pancreatic surgery centers.

    Massive hemoptysis mostly arises from the bronchial arteries; however, bleeding can also occur from a lesion in injured pulmonary arteries, such as pulmonary artery aneurysm/pseudoaneurysm (PAA/PAP), during pulmonary infection. A 66-year-old man was admitted with a diagnosis of lung abscess in the right lower lobe that was complicated with pyothorax. Intravenous administration of antibiotics and thoracic drainage successfully controlled the infection and inflammation until day 16, when the patient began to exhibit hemoptysis and bloody pleural effusion. Enhanced computed tomography (CT) with multi-planer reconstruction (MPR) images showed a highly enhanced mass inside the abscess fed by the pulmonary artery, suggesting PAA/PAP. Pulmonary angiography confirmed PAA/PAP, and embolization with coils successfully stopped both the bleeding into the sputum and pleural effusion, with a collapsed aneurysm visible on chest CT scan. Clinicians should consider the possibility of PAA/PAP in the differential diagnosis of hemoptysis during the treatment of patients with lung abscess. MPR CT is helpful for the diagnosis of PAA/PAP and its feeding vessels.

    This case illustrates successful treatment of a large postoperative intrasellar pseudoaneurysm with a polytetrafluoroethylene (PTFE)-covered stent. The advantages and potential disadvantages of this novel method of treatment are discussed. A previously healthy 59-year-old man underwent transsphenoidal operative treatment for hypophyseal macroadenoma,complicated by bleeding. On the 17 th postoperative day the patient had profuse arterial bleeding from his nose requiring posterior tamponade. Subsequent angiography of the left internal carotid artery(ICA) revealed a large pseudoaneurysm located intrasellarly, with the orifice in the anteromedial wall in the ophthalmic segment of the ICA.Surgical treatment of the pseudoaneurysm was considered very risky. A12-mm PTFE-covered stent (JoMed, Ulestraten, Netherlands), manually compressed on a PTCA-balloon (Maxxum 4.5/13 mm, Boston Scientific,Ireland) was endovascularly delivered covering the orifice of the pseudoaneurysm. Control angiography immediately after the intervention and one year later revealed no flow into the pseudoaneurysm and the ICA was fully patent. In conclusion, deployment of a PTFE-covered stent proved to be feasible and successful in the treatment of an intrasellariatrogenic ICA pseudoaneurysm. Adequate anticoagulative treatment after the procedure is essential to prevent thrombotic complications

    To evaluate the incidence, management, and outcome of visceral artery aneurysms (VAA) over one decade. 233 patients with 253 VAA were analyzed according to location, diameter, aneurysm type, aetiology, rupture, management, and outcome. VAA were localized at the splenic artery, coeliac trunk, renal artery, hepatic artery, superior mesenteric artery, and other locations. The aetiology was degenerative, iatrogenic after medical procedures, connective tissue disease, and others. The rate of rupture was much higher in pseudoaneurysms than true aneurysms (76.3 % vs.3.1 %). Fifty-nine VAA were treated by intervention (n = 45) or surgery (n = 14). Interventions included embolization with coils or glue, covered stents, or combinations of these. Thirty-five cases with ruptured VAA were treated on an emergency basis. There was no difference in size between ruptured and non-ruptured VAA. After interventional treatment, the 30-day mortality was 6.7 % in ruptured VAA compared to no mortality in non-ruptured cases. Follow-up included CT and/or MRI after a mean period of 18.0 ± 26.8 months. The current status of the patient was obtained by a structured telephone survey. Pseudoaneurysms of visceral arteries have a high risk for rupture. Aneurysm size seems to be no reliable predictor for rupture. Interventional treatment is safe and effective for management of VAA.

    We report 5 patients with hemoptysis due to infectious pulmonary artery pseudoaneurysm (PAP) treated with endovascular embolization using N-butyl cyanoacrylate (NBCA) injected via bronchial and nonbronchial systemic arterial approaches. Infectious diseases included inactive tuberculosis (n = 3), nontuberculous mycobacteriosis (n = 1), and chronic infection of unknown origin (n = 1). Seven PAPs were detected on selective systemic angiography, and injection of NBCA was performed. Disappearance of all PAPs was confirmed on systemic arteriography after the intervention. In all patients, hemoptysis was stopped without major complications, and it did not recur during the follow-up period (mean, 351 d; range, 285-427 d). Copyright © 2016 SIR. Published by Elsevier Inc.

    Purpose: This study was designed to evaluate the clinical success, complications, and transfusion requirements based on the location of and agents used for splenic artery embolization in patients with splenic trauma. Methods: A retrospective study was performed of patients with splenic trauma who underwent angiography and embolization from September 2000 to January 2010 at a level I trauma center. Electronic medical records were reviewed for demographics, imaging data, technical aspects of the procedure, and clinical outcomes. Results: Fifty patients were identified (34 men and 16 women), with an average age of 48 (range, 16-80) years. Extravasation was seen on initial angiography in 27 (54%) and was absent in 23 (46%). All 27 patients with extravasation were embolized, and 18 of 23 (78.2%) without extravasation were embolized empirically. Primary clinical success was similar (>75%) across all embolization locations, embolic agents, and grades of laceration treated. Of 45 patients treated, 9 patients (20%) were embolized in the main splenic artery, 34 (75.6%) in the splenic hilum, and 2 (4.4%) were embolized in both locations. Partial splenic infarctions developed in 47.3% treated in the splenic hilum compared with 12.5% treated in the main splenic artery. There were four (8.9%) mortalities: two occurred in patients with multiple critical injuries and two from nonbleeding etiologies. Conclusions: Embolization of traumatic splenic artery injuries is safe and effective, regardless of the location of treatment. Embolization in splenic hilar branches may have a higher incidence of infarction. The grade of laceration and agents used for embolotherapy did not impact the outcomes.

    To evaluate the diagnostic performance of obliteration of normal heterogeneous enhancement of the spleen (ONHES) on arterial phase (AP) computed tomography (CT) images in diffuse infiltrative splenic lymphoma (DISL). One hundred and thirty-six patients with lymphoma who had undergone two-phase (arterial and portal venous) abdominal CT were included in this study. We retrospectively evaluated the diagnostic performance of ONHES on AP CT in diagnosing DISL. Two observers evaluated ONHES on AP CT using the 5-point confidence level and assessed the presence or absence of subjective splenomegaly on axial CT images. Another two observers measured the splenic index as proposed by objective CT criteria. Statistical analysis included interobserver agreement and diagnostic performance of CT findings. Eleven of the 136 patients with lymphoma had DISL. The area under the receiver operating characteristic curve of ONHES (0.948 for observer 1 and 0.922 for observer 2) was superior to that of the splenic index (0.872 for observer 3 and 0.877 for observer 4), but the difference was not statistically significant (p > 0.05). The diagnostic performance of ONHES in conjunction with subjective splenomegaly showed higher diagnostic performance, as compared with subjective splenomegaly alone (accuracy: 100% and 85.3% for observer 1, 98.5% and 87.5% for observer 2; positive predictive value: 100% and 35.5% for observer 1, 90.9% and 39.3% for observer 2, respectively). Obliteration of normal heterogeneous enhancement of the spleen in conjunction with subjective splenomegaly can improve the diagnostic performance for DISL. Our results suggest that ONHES on AP CT images could be useful as an adjunctive diagnostic indicator of DISL in patients with lymphoma.

    Full Text Available Pseudoaneurysm of aorta is a rare condition usually seen after aortic surgeries or serious accidents. Here we report a 60 years old man without any previous medical condition who presented with non-specific symptoms and underwent different investigations for more than 1 year, until the presence of a continuous murmur raised suspicion toward his cardiovascular system. In echocardiographic and computed tomography (CT angiographic studies a large pseudoaneurysm of aortic arch with compression effect on pulmonary artery was detected. At this stage he remembered having suffered a minor trauma 10 years ago. He finally underwent operation and his aortic wall was repaired successfully with a patch. This case highlights the importance of thorough history taking and physical examination in patients irrespective of symptoms and high index of suspicion to detect this life-threatening condition.

    Full Text Available An 85-year-old woman developed severe swelling and pain in the proximal thigh after internal fixation of an intertrochanteric fracture of the femur with a hip nail. In order to identify the causes and determine the effective treatment, angiography was performed. The results of the angiography revealed a pseudoaneurysm of a branch of deep femoral artery. Endovascular embolization was used to treat the pseudoaneurysm. After reviewing all possible causes, we found a mistake in insertion of a guide wire for hip nail. Using intraoperative fluoroscopic images, we found the mal-positioned guide wire located posterior to trochanter on lateral view of hip. This case study reminds us that pseudoaneurysm can occur in a guide wire during hip nailing. Surgeons can avoid this complication with confirmation of lateral and anteroposterior view of hip.

    Delayed splenic vascular injury (DSVI) is traditionally considered a rare, often clinically occult, harbinger of splenic rupture in patients with splenic trauma that are managed conservatively. The purpose of our study was to assess the incidence of DSVI and associated features in patients admitted with blunt splenic trauma and managed nonoperatively. A retrospective analysis was conducted over a 4-y time. Patients admitted with blunt splenic trauma, managed no-operatively and with a follow-up contrast-enhanced computed tomography (CT) scan study during admission were included. The CT scans were reviewed for American Association for the Surgery of Trauma splenic injury score, amount of hemoperitoneum, and presence of DSVI. Logistic regression models were used to investigate the risk factors associated with DSVI. A total of 100 patients (60 men and 40 women) constituted the study group. Follow-up CT scan demonstrated a 23% incidence of DSVI. Splenic artery angiography validated DSVI in 15% of the total patient population. Most DSVIs were detected only on arterial phase CT scan imaging. The American Association for the Surgery of Trauma splenic injury score (odds ratio = 1.73; P = 0.045) and the amount of hemoperitoneum (odds ratio = 1.90; P = 0.023) on admission CT scan were associated with the development of DSVI on follow-up CT scan. DSVI on follow-up CT scan imaging of patients managed nonoperatively after splenic injury is common and associated with splenic injury score assessed on admission CT scan.

    2014-01-01

    Background There has been an increase in natural disasters in recent years, which leads to a great number of injuries and deaths. It still remains an unsolved problem to treat patients with vascular injury of solid organs effectively following natural disasters, but on-spot emergency interventional transcatheter arterial embolization (TAE) has been highly recommended to cure serious vascular injury of solid organs nowadays. Spleen is the most vulnerable abdominal organ, severe arterial hemorrhage of which can cause death if untreated timely. In this research, we aimed to study the possibility of performing emergency surgical intervention in mobile minimally invasive interventional shelter for splenic injury in the case of natural disasters. Methods First, the mobile minimally invasive interventional shelter was unfolded in the field, and then disinfection and preoperative preparation were performed immediately. Eight large animal models of splenic injury were created, and angiograms were performed using a digital subtraction angiography machine in the mobile minimally invasive interventional shelter, and then the hemostatic embolizations of injured splenic artery were performed following the established convention of rapid intervention therapy. The operating time was recorded, and the survival condition and postoperative complications were observed for two weeks. Results and discussion The average time of unfolding the shelter, and performing disinfection and preoperative preparation was 33 ± 7 min. The number of colonies in the sterilized shelter body was 86 ± 13 cfu/m3. The average TAE time was 31 ± 7 min. All the hemostatic embolizations of splenic injury were performed successfully in the mobile minimally invasive interventional shelter during the operation. A pseudoaneurysm was found in an animal model using angiography two weeks after the operation. The primary clinical success rate of embolization was 87.5%. The two-week survival rate in

    Objective: To find out the optimal primary surgical treatment options for infected pseudoaneurysm in intravenous drug abusers. Study Design: Cross sectional descriptive study. Place and Duration of Study: Department of Vascular Surgery, Combined Military Hospital Lahore, from Jan 2010 to Jun 2015. Material and Methods: A total of 31 consecutive patients with a history of intravenous drug abuse and an infected pseudoaneurysm in the groin or elbow, presenting in emergency department; were included in this study. All patients were primarily treated with ligation of the artery, excision of infected pseudoaneurysm and debridement of necrotic tissues. Only one patient underwent additional revascularization procedure. Results: All patients who underwent ligation and excision procedures did well initially. One (3.2%) patient developed severe distal ischemia after ligation of femoral artery within first 24 hours, so extra anatomic revascularization procedure was performed. Five (16.1%) patients required revascularization procedure after 16 weeks due to disabling distal ischemia. No amputation was needed and mortality rate was zero. Conclusion: Primary ligation of the artery with excision of infected pseudoaneurysm and necrotic material was found the optimal initial management for infected pseudoaneurysm in intravenous drug addicts. Ischemic complications if develop should be treated with early or late revascularization.

    A 48-year-old woman with severe juvenile-onset rheumatoid arthritis presented with a bleeding cutaneous sinus distal to her right total hip replacement scar. Methicillin resistant Staphylococcus aureus (MRSA) was isolated on culture. She had previously undergone bilateral total hip and knee replacements at aged 23 and six years later had the right knee prosthesis removed for infection, with subsequent osteomyelitis of the femoral shaft and right total hip prosthesis disruption. Peripheral arteriography was performed in view of persistent bleeding from the sinus, which revealed a 6 cm false aneurysm filling from and compressing the right external iliac artery (EIA). A PTFE-covered, balloon expandable JOSTENT was deployed in the right EIA, successfully excluding the false aneurysm and preventing further bleeding from the sinus. No graft infection was reported at 12 months. This case illustrates the potential use of endovascular stent-grafting in the treatment of an infected pseudoaneurysm

    We report our experience with the urgent treatment of two high-risk patients with infected femoral artery pseudoaneurysms (IFAPs) with the placement of a self-expandable covered stent (SECS). In both cases, there was no perioperative mortality and the aneurysm exclusion was successful without early or late stent thrombosis/stent fracture nor acute or chronic limb ischemia or limb loss. There was no recurrence of local or systemic infection during the follow-up period. Endovascular therapy represents a feasible treatment option for IFAPs in those patients for whom the risk of open surgical repair would be prohibitive, especially under urgent circumstances.

    Introduction The spleen is the second most frequently injured organ following blunt abdominal trauma. Trends in management have changed over the years. Traditionally, laparotomy and splenectomy was the standard management. Presently, nonoperative management (NOM) of splenic injury is the most common management strategy in hemodynamically stable patients. Splenic injuries can be managed via simple observation (OBS) or with angiography and embolization (AE). Angio-embolization has shown to be a valuable alternative to observational management and has increased the success rate of nonoperative management in many series. Diagnostics Improved imaging techniques and advances in interventional radiology have led to a better selection of patients who are amenable to nonoperative management. Despite this, there is still a lot of debate about which patients are prone to NOM. Angiography and Embolization The optimal patient selection is still a matter of debate and the role of CT and angio-embolization has not yet fully evolved. We discuss the role of sonography and CT features, such as contrast extravasation, pseudoaneurysms, arteriovenous fistulas, or hemoperitoneum, to determine the optimal patient selection for angiography and embolization. We also review the efficiency, technical considerations (proximal or selective embolization), logistics, and complication rates of AE for blunt traumatic splenic injuries. PMID:20668852

    A 67-year-old woman resented with an acute type A aortic dissection, which was treated surgically with aortic valve replacement as a composite graft with reimplantation of the coronary arteries. At the end of surgery, a left-ventricular venting catheter was placed through the apex and closed with a buffered suture. Consecutive computed tomography (CT) examinations verified a growing apex pseudoaneurysm. Communication between the ventricle and the pseudoaneurysm was successfully closed with an Amplatz septal plug by the transfemoral route. Follow-up CT showed an additional pseudoaneurysm, which also was successfully closed using the same method.

    A 48-year-old man with locally advanced pancreatic cancer underwent combined treatment with gemcitabine and proton radiation therapy. Because of subsequent obstruction of the common bile duct, a metallic biliary stent was placed and he received further gemcitabine chemotherapy. During chemotherapy, he developed an acute abdomen with a sudden-onset of tarry stool and jaundice. Gastroduodenoscopy revealed hemobilia from the biliary metallic stent. Contrast-enhanced abdominal computed tomography revealed the presence of a pseudoaneurysm arising from the right hepatic artery adjacent to the top of the stent. Hemostasis of the right hepatic artery pseudoaneurysm was achieved via transcatheter arterial embolization using cyanoacrylate. (author)

    Background. Post-traumatic hepatic artery pseudoaneurysms are rarely seen in children. Materials and methods. We retrospectively reviewed the radiologic studies and medical records of three patients treated at our institution and reviewed the literature. The patients (ages 5-13 years) presented immediately to 2 months after blunt (two patients) and penetrating (one patient) trauma. The hepatic pseudoaneurysms were discovered during work-up for fever (one patient), gastrointestinal bleeding and hyperbilirubinemia (one patient), or widened mediastinum (one patient) on chest radiograph. In two patients, the diagnosis was initially suspected by computed tomography (CT) examination and confirmed by angiography. In the third patient, the diagnosis was made initially by angiography. All three pseudoaneurysms were treated with transcatheter embolization. Results. All three embolizations were initially technically successful. However, there was recurrence in one case, in which embolization distal to the neck of the pseudoaneurysms was not technically possible. With conservative management, however, the residual lesion demonstrated spontaneous occlusion by ultrasound (US) at 6 months. Conclusion. This uncommon complication of liver trauma in children can have a delayed presentation, can be clinically unsuspected, and can follow blunt or penetrating trauma. Endovascular embolotherapy is the treatment of choice. (orig.) With 3 figs., 22 refs.

    We report a case of retroperitoneal hemorrhage due to multiple, small pseudoaneurysms complicating a chronic alcoholic pancreatitis. Cross-sectional imaging with CT and US could not clearly depict these vascular lesions. Selective arteriography of the superior mesenteric and gastroduodenal arteries clearly showed the small pseudoaneurysms and definitive treatment was performed by transcatheter embolization using coils. Eight months after successful embolization, the patient is asymptomatic without any recurrent bleeding. (orig.)

    Arterial damage is a known complication of brucellosis, but the occurrence of a thoracic aortic pseudoaneurysm secondary to brucellosis has not been previously reported. A 65-year-old Chinese man presented with a pseudoaneurysm in the descending segment of the thoracic aorta that caused symptoms of chest pain and intermittent fever. He was diagnosed with a thoracic aortic pseudoaneurysm secondary to brucellosis based on a positive brucella serology test (standard-tube agglutination test) and imaging examination (computed tomography angiography). Anti-brucellosis treatment and covered stent graft implantation were attempted to eliminate the brucellosis and pseudoaneurysm, respectively, and were ultimately successful, with no symptoms after 6 months of follow-up. Endovascular repair may be effective and safe for treating a thoracic aortic pseudoaneurysm resulting from brucellosis.

    To propose a less invasive surgical treatment for schistosomal portal hypertension. Ten consecutive patients with hepatosplenic schistosomiasis and portal hypertension with a history of upper gastrointestinal hemorrhage from esophageal varices rupture were evaluated in this study. Patients were subjected to a small supraumbilical laparotomy with the ligature of the splenic artery and left gastric vein. During the procedure, direct portal vein pressure before and after the ligatures was measured. Upper gastrointestinal endoscopy was performed at the 30(th) postoperative day, when esophageal varices diameter were measured and band ligature performed. During follow-up, other endoscopic procedures were performed according to endoscopy findings. There was no intra-operative mortality and all patients had confirmed histologic diagnoses of schistosomal portal hypertension. During the immediate postoperative period, two of the ten patients had complications, one characterized by a splenic infarction, and the other by an incision hematoma. Mean hospitalization time was 4.1 d (range: 2-7 d). Pre- and post-operative liver function tests did not show any significant changes. During endoscopy thirty days after surgery, a decrease in variceal diameters was observed in seven patients. During the follow-up period (57-72 mo), endoscopic therapy was performed and seven patients had their varices eradicated. Considering the late postoperative evaluation, nine patients had a decrease in variceal diameters. A mean of 3.9 endoscopic banding sessions were performed per patient. Two patients presented bleeding recurrence at the late postoperative period, which was controlled with endoscopic banding in one patient due to variceal rupture and presented as secondary to congestive gastropathy in the other patient. Both bleeding episodes were of minor degree with no hemodynamic consequences or need for blood transfusion. Ligature of the splenic artery and left gastric vein with supraumbilical

    Arterial wall disruption, as a consequence of inflammation\\/infection, trauma (penetrating or blunt), or iatrogenic causes, may result in pseudoaneurysm formation. Currently, iatrogenic causes are increasing as a result of the growth of endovascular intervention. The frequency of other causes also seems to be increasing, but this may simply be the result of increased diagnosis by better imaging techniques, such as multidetector contrast-enhanced computed tomography. Clinically, pseudoaneurysms may be silent, may present with local or systemic signs, or can rupture with catastrophic consequences. Open surgical repair, previously the mainstay of treatment, has largely been replaced by image-guided occlusion methods. On the basis of an experience of over 100 pseudoaneurysms, treatments at various anatomical sites, imaging modalities used for accurate diagnosis, current changing therapeutic options for pseudoaneurysm management, approved embolization agents, and clinical follow-up requirements to ensure adequate treatment will be discussed. Image-guided direct percutaneous and endovascular embolization of pseudoaneurysms are established treatment options with favorable success rates and minimal morbidity. The pendulum has now swung from invasive surgical repair of pseudoaneurysms to that of image-guided interventional radiology.

    We report a case that was successfully treated for massive lower gastrointestinal (LGI) bleeding due to a recurrent urinary bladder carcinoma. Treatment consisted of combination therapy including embolization of an inferior gluteal artery (IGA) pseudoaneurysm and low-dose arterial vasopressin infusion via a sigmoid artery (SA). A 57-year-old man presented with life-threatening sudden, massive LGI bleeding due to an obturator lymph node (LN) metastasis from a urinary bladder carcinoma. Computed tomography showed that the LN recurrence had invaded all the way to the sigmoid colon, and there was a pseudoaneurysm with extravasation inside the recurrence. An angiogram revealed a left IGA pseudoaneurysm. We therefore excluded the pseudoaneurysm by embolization with microcoils. Following this treatment the bleeding decreased, but intermittent LGI bleeding continued. Endoscopic examination showed the tumor with a huge ulcer inside the colonic lumen, and continuous oozing was confirmed. A second angiogram showed no recurrence of the IGA pseudoaneurysm and no apparent findings of bleeding. Then a 3F microcatheter was placed in the SA selectively using a coaxial catheter system, and vasopressin was infused at a rate 0.05 U/min for 12 h. Bleeding completely ceased 2 days later. There were no signs of ischemic gastrointestinal complications. Massive LGI bleeding has not recurred in 5 months.

    Epistaxis is a very common medical condition and can often be controlled with conservative measures. Rarely, uncontrolled and life-threatening epistaxis can occur. We present the case of a 58-year-old man who developed delayed, massive epistaxis caused by an extracranial left internal carotid artery pseudoaneurysm caused by an intranasal foreign object without apparent recent trauma. The patient was successfully treated with endovascular stenting of the affected vessel segment. Massive epistaxis is a potentially lethal condition. Although the source uncommonly originates from the internal carotid artery, pseudoaneurysm rupture needs to be considered on the differential diagnosis in selected patients. This case illustrates the need for vigilance for the presence of foreign objects and/or vessel injuries in the setting of acute, massive epistaxis. Additionally, we describe treatment options and review the literature. Copyright © 2016 Elsevier Inc. All rights reserved.

    Full Text Available Background. Parenteral drug abuse is the most common cause of infected femoral artery pseudoaneurysms (IFAP. This complication of intravenous drug abuse is not only limb threatening but can also be life threatening. The management of the IFAP is difficult and controversial. Generally speaking, ligation and excision of the pseudoaneurysm without revascularization is accepted procedure in majority of the patients. However it is not regarded as an appropriate procedure for cases where the high probability of amputation is expected from acute interruption of the femoral artery flow.Patients, methods and results. We present three cases of young (average 20 years, range 18–24 patients with IFAP, in which a primary reconstruction was performed due to absence of doppler signal over pedal arteries after ligation of common femoral artery. In two of them complications in form of haemorrhage and repeated infection developed in late postoperative period. The first one, had an excision and ligation while the second one had a reconstruction made by means of a silver impregnated dacron prosthesis. None of the patients required an amputation.Conclusions. Overall prognosis and prognosis of the reconstruction in parenteral drug abuse patients is uncertain because there is a high incidence of postoperative drug injection despite aggressive drug rehabilitation.

  5. Tortuosity and calcification of the splenic artery. More than an additional finding; Schlaengelung und Verkalkung der Milzarterie im Roentgenbild. Mehr als ein Nebenbefund

    Tortuosity of the splenic artery and calcification of the vessel wall are typical additional findings on plain abdominal x-ray. The combination of both anomalies is common in elderly persons presenting without symptoms of splenic ischemia. Its pathogenesis is thought to be multifactorial. In infancy and childhood, the splenic artery is stretched in its entire course. A growing difference between the length of the vessel and the distance between its origin and the splenic hilum gives rise to tortuosity. The artery's proximal segment is involved more frequently and more severely than the distal one. The tortuous route of the vessel is accentuated by the direction of its major branches, which is roughly perpendicular to the main trajectory. Neither tortuosity nor calcification should be taken to be risk factors for the comparatively common splenic artery aneurysm. Calcific deposits are not confined to the media but are also detected in the intima of the vascular wall. Critical narrowings of the lumen arising on the calcium deposits are not observed. Calcifying atherosclerosis of the splenic artery is comparable to medial sclerosis of the peripheral arteries frequently noticed in diabetics and dialysis patients. Only the less important calcification of the intima may be attributed to mechanisms of the hydrohemodynamic theory of atherosclerosis. The spleen's blood storage capacity may contribute to the characteristic age-dependent alterations of the shape and course of the splenic artery. (orig.)

    Nonoperative management (NOM) of blunt splenic injuries has been widely accepted, and the application of splenic artery embolization (SAE) has become an effective adjunct to NOM. However, complications do occur after SAE. In this study, we assess the factors leading to the major complications associated with SAE. Focusing on the major complications after SAE, we retrospectively studied patients who received SAE and were admitted to 2 major referral trauma centers under the same established algorithm for management of blunt splenic injuries. The demographics, angiographic findings, and factors for major complications after SAE were examined. Major complications were considered to be direct adverse effects arising from SAE that were potentially fatal or were capable of causing disability. There were a total of 261 patients with blunt splenic injuries in this study. Of the 261 patients, 53 underwent SAE, 11 (21%) of whom were noted to have 12 major complications: 8 cases of postprocedural bleeding, 2 cases of total infarction, 1 case of splenic abscess, and 1 case of splenic atrophy. Patients older than 65 years were more susceptible to major complications after SAE. Splenic artery embolization is considered an effective adjunct to NOM in patients with blunt splenic injuries. However, risks of major complications do exist, and being elderly is, in part, associated with a higher major complication incidence. Copyright © 2011 Elsevier Inc. All rights reserved.

    Splenic artery aneurysm (SAA) is a rare and extremely difficult diagnosis. A rare case of a ruptured SAA in a 38-year old female, firstly treated with endovascular embolization and then with splenectomy, is presented. A 38-year old female presented to the emergency department with epigastric pain and fainting episodes. Direct catheter angiography revealed a ruptured SAA and distal, as well as proximal coil embolization was performed. Due to abdominal compartment syndrome the patient underwent open surgery with splenic artery ligation and splenectomy. Postoperative she showed signs of sepsis and was treated with i.v. fluids, steroids, packed red blood cells, platelets, fresh frozen plasma and antimicrobial treatment. Additionally, a multidrug resistant Acinetobacter baumanni was yielded from the urine culture. She had a satisfactory recovery. She is followed up a total of 5 years with no signs of overwhelming post-splenectomy infection syndrome. Direct catheter angiography is a very helpful option in diagnosis, as well as treatment, but a close monitoring after embolization is essential. Furthermore, post-splenectomy sepsis is a severe disease with high mortality rates that requires immediate appropriate treatment.

Clinical files, multidetector row computed tomography angiography, and angiographic examinations along with procedure details were reviewed.ResultsSeventeen SAPAs were present, predominantly located on gastroduodenal or pancreatic arteries (9/17; 53 %). Angiography showed extravasation of contrast medium from SAPA in 15/17 patients (88 %). Technical success rate of TAE was 100 %. TAE was performed using metallic coils in all patients (100 %), in association with gelatin sponge in 5/17 patients (29 %). TAE allowed controlling the bleeding and returning to normal hemodynamic status in 16/17 patients (94 %). In 1/17 patient (6 %), surgery was needed to definitively control the bleeding. The mortality and morbidity rate of TAE at 30 days were 0 and 12 %, respectively. Morbidity consisted in coil migration in 1/17 patient (6 %) and transient serum liver enzyme elevation in 1/17 patient (6 %).ConclusionTAE is an effective and safe treatment option for ruptured SAPA in hemodynamically unstable patients, with a success rate of 94 %.

    Splenic artery aneurysm (SAA) is a well-known complication of chronic liver disease and portal hypertension in adults. The incidence of SAA in children undergoing selective hepatic angiography prior to liver transplantation is reported as 4%, but there are few systematic studies. To investigate the SAAs detected by multidetector CT angiography (MDCTA) among children with chronic liver disease. A total of 124 children (71 girls, 53 boys; mean age 118 months; age range 5 days to 204 months) with chronic liver disease underwent MDCTA to display the vascular anatomy and any vascular complications during the pretransplantation period. Of these children, 23 also underwent coeliac angiography. The digital subtraction angiography (DSA) and MDCTA findings were compared. SAAs were detected in 13 children (10.4%); none was detectable by US. All patients had more than one aneurysm; ten patients had more than three. In all except one patient, the SAAs were located only in the intraparenchymal branches of the splenic artery; in one patient they were located in the intraparenchymal segment and in the distal third of the splenic artery. The mean size of the aneurysms was 6.5 mm (range 2.5-18 mm). All patients with aneurysms had splenomegaly and vascular collaterals. Nine of the children with SAAs had portal vein pathologies (two occlusions, two stenoses, five dilatations). A statistically significant difference existed with regard to the size of spleen (P < 0.05) and patient age (P < 0.05) between children with SAAs and children without SAAs. There was an increased risk of SAAs in patients with portal vein pathologies. In 19 patients without SAAs on MDCTA, no SAAs were seen on DSA. It is likely that the incidence of SAA in children with chronic liver disease will increase with improved survival of children with long-standing portal hypertension and chronic liver disease. MDCTA with multiplanar reconstruction is a noninvasive and effective means of imaging paediatric patients with

It is likely that the incidence of SAA in children with chronic liver disease will increase with improved survival of children with long-standing portal hypertension and chronic liver disease. MDCTA with multiplanar reconstruction is a noninvasive and effective means of imaging paediatric patients with

    Pseudoaneurysm of ascending aorta is an infrequent but well-recognized and potentially fatal complication after cardiac surgeries. The complication can develop early, delayed or late, and the presentation is also varied. We are presenting here two cases of pseudoaneurysm of ascending aorta following cardiac surgery that were successfully managed by the transcatheter method. The first one occurred following coronary artery bypass surgery and the second one occurred following double-valve replacement surgery. The aortic openings of these aneurysms were occluded with 12 mm and 10 mm atrial septal occluders, respectively, with a good outcome. An immediate postprocedure angiogram showed no residual flow into the sac. Six months of follow-up of both cases also showed excellent results

    Ultrasound-guided thrombin injection (UGTI) of femoral artery pseudoaneurysms after endovascular procedures is an effective therapy. There is controversy in the literature regarding injecting pseudoaneurysms with short and/or wide necks. This article reports our experience in UGTI of pseudoaneurysms in 1 hospital regarding the efficacy of this treatment in all pseudoaneurysms regardless of the size of the necks. A retrospective review of 46 patients diagnosed between 2011 and 2016 with groin pseudoaneurysms using established duplex ultrasound criteria. Mean age was 68 years (range 27-87). Ten pseudoaneurysms thrombosed spontaneously, 5 were thrombosed by ultrasound-guided compression, and 2 were treated surgically due to disqualifying criteria. In this retrospective review, we analyzed the remaining 29 pseudoaneurysms regarding the dimensions of their neck lengths and outcomes after attempting thrombin injection. The mean aneurysm neck length and width were 1.03 ± 0.9 cm and 0.30 ± 0.1 cm, respectively. All 29 patients were evaluated with respect to pseudoaneurysm size, neck length, neck width, and complexity. Successful treatment of 29 pseudoaneurysms (2 external iliac, 20 common femoral, 2 deep femoral, and 5 superficial femoral) with UGTI was achieved without complications in 100% of the cases, regardless of pseudoaneurysm size, neck dimensions, or complexity. Anticoagulation status did not affect the efficacy of the procedure. Nine of the 29 pseudoaneurysms (31.0%) had neck length less than 0.5 cm. This study demonstrates the safety and efficacy of UGTI in treating iatrogenic pseudoaneurysm in 29 of 29 patients, even in patients with pseudoaneurysm with short neck lengths. Our experiences support injecting all pseudoaneurysms irrespective of dimension. Copyright © 2017 Elsevier Inc. All rights reserved.

    The interventional angiographic techniques using the percutaneous femoral approach for endovascular revascularization are becoming increasingly more popular. These methods usually require larger sheaths, and most patients need postprocedural anticoagulation or antiplatelet therapy. As a consequence, the interventional procedure is associated with a higher rate of complications at the arterial entry site compared to diagnostic angiography. The reported incidence of iatrogenic pseudoaneurysm formation after coronary artery interventions ranges from 3.2% to 7.7%, and the rates noted after diagnostic angiography range from 0.2% to 1%. Peripheral pseudoaneurysms have traditionally been treated by surgical intervention, but nonsurgical alternatives, such as ultrasound (US)-guided compression, coil embolization, stent-graft placement, and percutaneous thrombin injection with or without balloon occlusion have also been documented. Of these alternatives, direct percutaneous embolization with embolic agents is the most popular method. The tissue adhesive n-butyl cyanoacrylate (NBCA) (Hystoacryl) (B. Braun, Melsungen, Germany) is one of the most popular occluding agents for neurovascular interventions, and has been widely used for more than 20 years [5,6]. In this study, we evaluated the efficacy and utility of direct percutaneous injection of NBCA for embolization of femoral pseudoaneurysms

    28 patients with chronic Immunogenic (Idiopathic) Thrombocytopenic purpura (ITP) were determined of the site of sequestration using 99m Tc labeled platelets. Among them, partial splenic artery embolization were done in 20 patients. 7/8 spleen type cases and 1/6 hepato-spleen hepatic type cases have their platelets counts raised above 100 x 10 9 /L. The separation of platelets and its 99m Tc labelling method were also discussed. Above results suggested that the determination of sequestration site of the 99m Tc labelled platelets have some help for the splenic artery embolization therapy in ITP

    Visceral aneurysms are potentially life-threatening vascular lesions. Superior mesenteric artery (SMA) pseudoaneurysms are a rare but well-recognized complication of chronic pancreatitis. Open surgical repair of such an aneurysm, especially in patients after previous surgical treatment, might be dangerous and risky. Stent graft implantation makes SMA pseudoaneurysm exclusion possible and therefore avoids a major abdominal operation. Percutaneous direct thrombin injection is also one of the methods of treating aneurysms in this area. We report a first case of percutaneous ultrasound-guided thrombin injection to complete SMA pseudoaneurysm exclusion after an unsuccessful endograft placement. Six-month follow-up did not demonstrate any signs of aneurysm recurrence

    In this case report, the authors are presenting a case of a 35-year-old lady who presented to our clinic with recurrent episodes of massive epistaxis and loss of right eye vision for last 6 months following road traffic accident. There was no other significant medical and surgical history. Bleeding episodes were sometimes very severe with loss up to 400-500 cc and would stop spontaneously. She was given multiple blood transfusions after these episodes. A complete otorhinolaryngological examination including rigid endoscopy and coagulation investigation did not reveal any abnormality. CT with contrast of paranasal region showed blood within the right sphenoid sinus with linear fracture of the lateral wall with post-traumatic cavernous pseudoaneurysm of internal carotid artery localised to right sphenoid sinus. That was managed successfully by embolisation using a detachable balloon and a coil. She was followed up in the clinic at 6 weeks and 6 months interval with no symptoms.

    Pseudoaneurysm of the ascending aorta is an uncommon pathology and a challenge in high-risk patients who undergo conventional surgery because of high operative morbidity and mortality. Endovascular exclusion of an aortic pseudoaneurysm using an endoprosthesis is a less invasive approach, but few such cases have been reported. Moreover, the use of this approach poses unique therapeutic challenges because there is no specific endoprosthesis for ascending aortic repair, particularly to treat patients with previous coronary artery bypass graft (CABG). We describe the case of a 74-year-old patient who had undergone CABG and later presented with an iatrogenic ascending aortic pseudoaneurysm that occurred during an angiography. This patient was at very high risk for surgical treatment and, therefore, an endovascular approach was adopted: percutaneous coronary intervention for the left main coronary artery, left anterior descending and left circumflex native coronary arteries followed by endovascular endoprosthesis deployment in the ascending aorta to exclude the pseudoaneurysm. Both procedures were successfully performed, and the patient was discharged without complications 4 days later. At 5 months' clinical follow-up, his clinical condition was good and he had no complications. Copyright © 2011 Wiley-Liss, Inc.

    Objective: To explore the better diagnostic method for acute splenic artery injury through comparative analysis of CT and DSA. Methods: Fifty-seven patients with acute splenic injury were examined by CT and DSA, treated with splenic arterial embolization and then undertook follow up. Results: CT examination possessed higher sensitivity and accuracy than DSA in demonstrating splenic parenchymal laceration, intrasplenic hematoma, subcapsular hematoma, rupture of splenic capsule and combined injury of intra-abdominal organs, especially in localizing splenic laceration. And there was a high significant difference statistically between the two kinds of examination (χ 2 =10.71, P 2 =12.57, P<0.005). Conclusions: CT and DSA are complementary in the diagnosis of splenic injury. After CT confirmation of splenic injury and the patient vital signs being stable, DSA should be referred to as soon as possible for further detail information as well as for possible interventional embolization and reduction of surgical complications.

    injury. In this context, non-operative management (NOM) has gradually become the standard as long as the patient remains hemodynamically stable and there is no suspicion of injury to hollow viscera, with the patient being carefully monitored on a surgical service. The development of arteriography with splenic artery embolization has increased the rate of splenic salvage; this can be performed electively based on specific indications (blush on CT, pseudoaneurysm, arteriovenous fistula), and may also be considered for severe splenic injury, abundant hemoperitoneum, or severe polytrauma. For pancreatic injury, in addition to CT scan, magnetic resonance pancreatography (MRCP) or even endoscopic retrograde cholangiopancreatography (ERCP) may be necessary to identify a ductal rupture. If the pancreatic duct is intact, laboratory and CT imaging surveillance is performed just as for splenic injury. In case of pancreatic ductal injury, ERCP stenting can be considered. However, if this is unsuccessful, the therapeutic decision can be difficult: while NOM can still be successful, complications may arise that are difficult to treat while distal pancreatectomy, although initially more agressive may avoid these complications if performed early.

    2010-01-01

    Although the exact benefit of adjunctive splenic artery embolization (SAE) in the nonoperative management (NOM) of patients with blunt splenic trauma has been debated, the role of transcatheter embolization in delayed splenic hemorrhage is rarely addressed. The purpose of this study was to evaluate the effectiveness of SAE in the management of patients who presented at least 3 days after initial splenic trauma with delayed hemorrhage. During a 24-month period 4 patients (all male; ages 19-49 years) presented with acute onset of pain 5-70 days after blunt trauma to the left upper quadrant. Two had known splenic injuries that had been managed nonoperatively. All had computed axial tomography evidence of active splenic hemorrhage or false aneurysm on representation. All underwent successful SAE. Follow-up ranged from 28 to 370 days. These cases and a review of the literature indicate that SAE is safe and effective for NOM failure caused by delayed manifestations of splenic arterial injury.

    We reported a case of pseudoaneurysm in the upper lobar branch of the right pulmonary artery, which was caused by a fungus ball within the progressive massive fibrosis (PMF) in a patient with pneumoconiosis. Coil embolization of the pseudoaneurysm initially stopped the bleeding. After right upper lobe lobectomy to prevent the recurrent hemoptysis, pathology confirmed pseudoaneurysm within the PMF due to aspergilloma.

    Objective: To analyze the effects and the complications of partial splenic artery embolization (PSE) and splenectomy offering a feasible way to choose different therapeutic methods for hypersplenism. Methods: Forty-six patients treated with PSE and thirty-three undergone splenectomy were compared for their effectivenesses and complications in treating hypersplenism. Results: Thrombocyte and leucocyte counts increased markedly after the two kinds of treatment (P 0.05). The complication rate of the PSE was far more than that of the splenectomy (P<0.001). Conclusions Splenectomy is prior to PSE on patients with large mount of ascites, serious portal hypertension and splenomegaly. PSE is suitable for patients with poor liver function, blood coagulation disturbance, liver cancer complicated with hypersplenism and aging. (authors)

    To test the splenic blood flow change after radiofrequency ablation (RFA) of the spleen in a porcine experimental model. Six pigs underwent RFA of the spleen via laparotomy. During the procedure of RFA, clamping of splenic artery (one) and both splenic artery/vein (one) was also performed. Measurement of blood flow of both splenic artery (SA) and splenic vein (SV) with flow-wire at pre- and post-RFA of the spleen was also performed. Ablated splenic lesions were created as estimating ∼50% area of the spleen in all pigs. Resected specimens reveal not only the coagulated necrosis but also the congestion of the spleen. On the SA hemodynamics, maximum peak velocity (MPV) changed from 37 ± 7 to 24 ± 8 cm/s (normal), 11 to 10 cm/s (clamp of the SA), and 12 to 7.5 cm/s (clamp of both SA/SV), respectively. On the SV hemodynamic, MPV changed from 15 ± 5 to 13 ± 4 cm/s (normal), 17 to 15 cm/s (clamp of the SA), and 17 to 26 cm/s (clamp of both SA/SV), respectively. RFA of the spleen could induce coagulation necrosis and reduce the splenic arterial blood flow.

    Following blunt splenic injury, there is conflicting evidence regarding the natural history and appropriate management of patients with vascular injuries of the spleen such as pseudoaneurysms or blushes. The purpose of this study was to describe the current management and outcomes of patients with pseudoaneurysm or blush. Data were collected on adult (aged ≥18 years) patients with blunt splenic injury and a splenic vascular injury from 17 trauma centers. Demographic, physiologic, radiographic, and injury characteristics were gathered. Management and outcomes were collected. Univariate and multivariable analyses were used to determine factors associated with splenectomy. Two hundred patients with a vascular abnormality on computed tomography scan were enrolled. Of those, 14.5% were managed with early splenectomy. Of the remaining patients, 59% underwent angiography and embolization (ANGIO), and 26.5% were observed. Of those who underwent ANGIO, 5.9% had a repeat ANGIO, and 6.8% had splenectomy. Of those observed, 9.4% had a delayed ANGIO, and 7.6% underwent splenectomy. There were no statistically significant differences between those observed and those who underwent ANGIO. There were 111 computed tomography scans with splenic vascular injuries available for review by an expert trauma radiologist. The concordance between the original classification of the type of vascular abnormality and the expert radiologist's interpretation was 56.3%. Based on expert review, the presence of an actively bleeding vascular injury was associated with a 40.9% risk of splenectomy. This was significantly higher than those with a nonbleeding vascular injury. In this series, the vast majority of patients are managed with ANGIO and usually embolization, whereas splenectomy remains a rare event. However, patients with a bleeding vascular injury of the spleen are at high risk of nonoperative failure, no matter the strategy used for management. This group may warrant closer observation or

    Traumatic pseudoaneurysm of the intracavernous internal carotid artery (ICA) is a very rare cause of epistaxis but is a life-threatening clinical situation when left untreated. The authors have experienced four cases of traumatic pseudoaneurysm involving the intracavernous ICA. Delayed massive epistaxes developed 1 to 8 months after trauma and initial transient epistaxis in all four patients. Three of the cases were successfully managed by the detachable balloon occlusion (DBO) of the ICA along with the aneurysm openings. In one case, a large pseudoaneurysm destroying a large area of the central skull base with peripheral blood clot was demonstrated on computed tomography, magnetic resonance imaging, and angiography; this patient died due to massive epistaxis before the trial of DBO. Imaging findings of pseudoaneurysms involving the intracavernous ICA in the four cases are described, and the role of endovascular treatment is discussed.

    2014-01-01

    Full Text Available Peroneal artery arteriovenous fistulas and pseudoaneurysms are extremely rare with the majority of reported cases due to penetrating, orthopedic, or iatrogenic trauma. Failure to diagnose this unusual vascular pathology may lead to massive hemorrhage or limb threatening ischemia. We report an interesting case of a 14-year-old male who presented with acute musculoskeletal pain of his lower extremity. Initial radiographs were negative. Further imaging workup revealed a peroneal arteriovenous fistula with a large pseudoaneurysm. After initial endovascular intervention was unsuccessful, the vessels were surgically ligated in the operating room. Pathology revealed papillary endothelial hyperplasia consistent with an aneurysm and later genetic testing was consistent with Ehlers-Danlos syndrome Type IV. This case illustrates an unusual cause of acute atraumatic musculoskeletal pain and uncommon presentation of Ehlers-Danlos syndrome.

    Quantitative assessment of hepatic and splenic blood flow detected by injecting Tc-99m-Sn colloid as a bolus was performed on 75 patients who were suspected of having liver disease. Using a computer, the hepatic and splenic time-activity curves were analyzed. Hepatic index was calculated as the ratio of arterial to portal blood flow. The peak time of the right kidney was corresponded to the junction of the arterial and portal phases of the hepatic curve. Splenic index was calculated as the ratio of splenic arterial to liver arterial blood flow. Hepatic and splenic indices had elevated in cases of liver cirrhosis and hepatoma than those of normal controls. There was no significant difference in the hepatic and splenic indices among chronic hepatitis, liver metastasis and normal subject. These noninvasive tests for the hepatic and splenic blood flow may be useful in writing a report of liver scintigram because of the added information of the liver. (author)

    This study aimed to evaluate if variation in management of blunt splenic injury (BSI) among Level I trauma centers is associated with different outcomes related to the use of splenic artery embolization (SAE). All adult patients admitted for BSI from 2008 to 2010 at 4 Level I trauma centers were reviewed. Use of SAE was determined, and outcomes of spleen salvage and nonoperative management (NOM) failure were evaluated. A priori, a 10% SAE rate was used to group centers into high- or low-use groups. There were 1,275 BSI patients. There were intercenter differences in age, injury severity, and grade of spleen injury (Spleen Injury Scale [SIS]). Mortality was similar by center; however, BSI treatment varied significantly by center. Overall, SAE use was highest at center A compared with B, C, and D (19%, 11%, 1%, and 4%, respectively; p trauma centers. Centers with higher rates of SAE use have higher spleen salvage and less NOM failure. SAE was shown to be an independent predictor of spleen salvage. Therapeutic study, level IV.

    2017-05-01

    Full Text Available Uterine artery pseudoaneurysms (UAPs are rare vascular lesions that may be life threatening if not diagnosed and properly treated. The clinical presentation of UAPs includes a spectrum of symptoms that are often associated with other and more frequent gynecologic/obstetric pathologies, both with and without vaginal bleeding, and may span from postpartum hemorrhage to the absence of symptoms. We report cases of two patients with UAP, both of whom were diagnosed with ultrasonography and contrast-enhanced computed tomography and successfully treated with transcatheter embolization. The first patient presented delayed hypovolemic shock following surgery for endometriosis, whereas the second patient suffered from postpartum hemorrhage after cesarean section. Diagnosis of UAPs relies on noninvasive imaging; transcatheter arterial embolization is an effective treatment to control bleeding in both hemodynamically stable and unstable patients.

    Splenic artery embolization (SAE), proximal or distal, is becoming the standard of care for traumatic splenic injury. Theoretically the immunological function of the spleen may be preserved, but this has not yet been proven. A parameter for measuring the remaining splenic function must therefore be determined in order to decide whether or not vaccinations and/or antibiotic prophylaxis are necessary to prevent an overwhelming post-splenectomy infection (OPSI). A systematic review of the literature was performed July 2015 by searching the Embase and Medline databases. Articles were eligible if they described at least two trauma patients and the subject was splenic function. Description of procedure and/or success rate of SAE was not necessary for inclusion. Two reviewers independently assessed the eligibility and the quality of the articles and performed the data extraction. Twelve studies were included, eleven with adult patients and one focusing on children. All studies used different parameters to assess splenic function. None of them reported a OPSI after splenic embolization. Eleven studies found a preserved splenic function after SAE, in both adults and children. All but one studies on the long term effects of SAE indicate a preserved splenic function. However, there is still no single parameter or test available which can demonstrate that unequivocally.

    In laparoscopic distal pancreatectomy (LDP), isolating the splenic artery and vein requires advanced techniques. This study aimed to assess the efficacy of a novel method termed the 'straightened splenic vessels' (SSV) method for isolating the splenic vessels in LDP. In SSV, to adjust the instrument axis, the splenic artery was straightened by grasping 2 points of its nerve sheath. Then, the layer between the splenic artery's nerve sheath and the pancreatic parenchyma was dissected. Next, the pancreas was mobilized from body to tail, and the splenic vein was straightened by 3-point retraction before isolation. To evaluate this method's efficacy, we investigated 51 patients who underwent LDP. In 39 patients who underwent LDP with splenectomy, the mean operating time was significantly shorter in the SSV group than in the conventional group (p = 0.004). In 12 patients who underwent LDP with preserving the splenic vessels, the mean intraoperative blood loss in the SSV group was 27.6 ml, which was significantly lower than that in the conventional group (p = 0.012). This method may be applied as a standard procedure with little blood loss and short operation time for LDP. Larger prospective studies are needed to further evaluate the feasibility. © 2017 S.

    Full Text Available Pseudo-aneurysm of the femoral artery is the most common arterial complication in drug injecting abusers. Scholars in vascular surgery have published debating statements regarding techniques of successful surgical management during last two decades. We present the results of simple arterial ligation in a series of 32 patients presenting with infected femoral pseudo-aneurysm. Most of the patients were males (89%. Young persons in the age group of 15-44 years were mostly affected. Site of lesion included common femoral artery in 65% , superficial femoral artery 28% and at bifurcation 6.2%. celulitis in 14 (53%, abscess & "ncelulitis in 6 (19%, necrosing fasciitis in 2 (6.2% and vascular abscess in 7 (22% cases were the forms of associated local infection. There was no hemorrhage, vascular thrombosis, amputation, or mortality. Claudicating were the only complications identified in 2 patients with Tripe ligation. Ligation is the optimal management for infected pseudo-aneurysms because it is easy, cost-effective, and safe. Early reconstruction is not recommended, since there is an extended infection in the location of the pseudo-aneurysm.

    Objective: To explore the diagnosis and treatment of traumatic carotid cavernous fistula combined with sphenoid sinus pseudoaneurysm. Methods: Interventional diagnosed and treated 6 eases of traumatid carotid cavernous fistula combined with sphenoid sinus pseudoaneurysm. Results: 5 patients presented with recurrent massive epistaxis and symptoms of CCF caused by pseudoaneurysms and fistulas were occluded with detachable balloons and internal carotid arteries were reserved in 2 cases; of which, 1 case also had indirect carotid cavernous fistula in contralateral side, embolizated by trans facial vein approach with microcoil. Complete symptoms resolution was achieved in all cases, without procedure related complications. During the follow-up period, all patients returned to their work. Conclusions: Falling from high speed motorcycle without helmet may be one of the main causes of this disease. The site of strike mostly localize at the frontal and lateral aspects of the orbit. MRI scan is very helpful for the diagnosis before receiving angiography. Detachable balloon occlusion for the pseudoaneurysm and fistula is safe and efficient for the treatment. (authors)

    Splenic artery embolization (SAE) is increasingly being used as a nonoperative management strategy for patients with blunt splenic injury following trauma. The aim of this study was to assess the splenic function of patients who were embolized. A clinical study was performed, with splenic function assessed by examining the antibody response to polysaccharide antigens (pneumococcal 23-valent polysaccharide vaccine), B-cell subsets, and the presence of Howell-Jolly bodies (HJB). The data were compared to those obtained from splenectomized patients and healthy controls (HC) who had been included in a previously conducted study. A total of 30 patients were studied: 5 who had proximal SAE, 7 who had distal SAE, 8 who had a splenectomy, and 10 HC. The median vaccine-specific antibody response of the SAE patients (fold increase, 3.97) did not differ significantly from that of the HC (5.29; P = 0.90); however, the median response of the splenectomized patients (2.30) did differ (P = 0.003). In 2 of the proximally embolized patients and none of the distally embolized patients, the ratio of the IgG antibody level postvaccination compared to that prevaccination was splenic immune function of embolized patients was preserved, and therefore routine vaccination appears not to be indicated. Although the median antibody responses did not differ between the patients who underwent proximal SAE and those who underwent distal SAE, 2 of the 5 proximally embolized patients had insufficient responses to vaccination, whereas none of the distally embolized patients exhibited an insufficient response. Further research should be done to confirm this finding. Copyright © 2014, American Society for Microbiology. All Rights Reserved.

  18. Life-threatening hemobilia caused by hepatic pseudoaneurysm after T-tube choledochostomy: report of a case

    Full Text Available Abstract Background Hemobilia is a rare but lethal biliary tract complication. There are several causes of hemobilia which might be classified as traumatic or nontraumatic. Hemobilia caused by pseudoaneurysm might result from hepatobiliary surgery or percutaneous interventional hepatobiliary procedures. However, to our knowledge, there are no previous reports pertaining to hemobilia caused by hepatic pseudoaneurysm after T-tube choledochostomy. Case presentation A 65-year-old male was admitted to our hospital because of acute calculous cholecystitis and cholangitis. He underwent cholecystectomy, choledocholithotomy via a right upper quadrant laparotomy and a temporary T-tube choledochostomy was created. However, on the 19th day after operation, he suffered from sudden onset of hematemesis and massive fresh blood drainage from the T-tube choledochostomy. Imaging studies confirmed the diagnosis of pseudoaneurysm associated hemobilia. The probable association of T-tube choledochostomy with pseudoaneurysm and hemobilia is also demonstrated. He underwent emergent selective microcoils emobolization to occlude the feeding artery of the pseudoaneurysm. Conclusions Pseudoaneurysm associated hemobilia may occur after T-tube choledochostomy. This case also highlights the importance that hemobilia should be highly suspected in a patient presenting with jaundice, right upper quadrant abdominal pain and upper gastrointestinal bleeding after liver or biliary surgery.

    Full Text Available Background. Splenic artery aneurysm (SAA is an uncommon and difficult diagnosis. SAA is more common in females. Only 20% of SAA is symptomatic and may present as a rupture. A ruptured SAA is associated with a 25% mortality rate. Case Presentation. We present a case of a male patient with a bleeding SAA that rapidly increased in size. Distal coiling was technically impossible and despite proximal coil embolisation the SAA continued to bleed. A laparotomy including splenectomy and partial pancreatectomy was performed with an uneventful patient recovery. Discussion. Endovascular management is currently considered the optimal treatment of SAA. However, careful monitoring and follow-up is needed after embolisation as rapid recanalization of the SAA may possibly occur, especially when distal coiling of the aneurysm is unsuccessful. Conclusion. Endovascular treatment of an SAA is not necessarily effective. Surgeons must be prepared to perform open procedures to further reduce mortality rates.

    Discussion & conclusion: Questions still remain regarding the timing of repeat imaging for diagnosis of SPA following non-operative blunt splenic trauma, which patients should be imaged, and how to manage SPA upon diagnosis. More clinical study and basic science research is warranted to study the disease process of SPA in pediatric patient. We believe that our proposed management algorithm timely detect formation of delayed SPA formation and addresses the possible fatal disease course of pediatric SPA.

    Internal carotid artery pseudoaneurysm is a rare life-threatening condition that may develop in different clinical situations. We report the case of an extracranial internal carotid artery pseudoaneurysm secondary to a throat infection in a pediatric patient that was initially treated with percutaneous thrombin injection under ultrasound guidance. However, recanalization occurred at 48 h, and definitive treatment was then performed by endovascular stent-graft placement. We briefly review the clinical characteristics of this uncommon clinical condition as well as the treatment options.

    Extracranial carotid pseudoaneurysms are uncommon vascular lesions. Even with conservative management complications can happen, such as delayed cerebral embolization or symptoms due to flow limitation. Although endovascular therapy can be curative, literature demonstrating a preferred technique is scant. Our goal was to evaluate the use of 1 technique only-the deployment of overlapping self-expandable porous stents-to treat a series of extracranial carotid pseudoaneurysms. From 2008 to 2014, 14 consecutive cases of symptomatic extracranial carotid pseudoaneurysms were managed with single or multilayer porous stents at our institution. Each patient underwent a standardized angiographic follow-up at 6 months. Twelve patients also received a follow-up computed tomography angiogram at 12 months, and yearly thereafter (median radiographic follow-up, 38 months). The total clinical follow-up period ranged between 6 and 69 months (median, 46 months). In our series, each of the extracranial carotid pseudoaneurysms appeared to be the result of carotid artery dissection with associated carotid stenosis at the origin of every pseudoaneurysm. Endovascular treatment consisted of 1-3 layers of self-expandable porous stents placed without balloon angioplasty. Immediately after stenting angiographic images were notable for stagnant opacification of the pseudoaneurysm through the stent(s). All pseudoaneurysms were completely obliterated by the 6-month follow-up angiogram and remained so throughout the radiographic follow-up period. Complications were minimal, consisting of 1 patient developing a mild Horner's syndrome after treatment that resolved during clinical follow-up. Extracranial carotid pseudoaneurysms can be successfully obliterated with the use of porous, self-expandable stents. Copyright © 2016 Elsevier Inc. All rights reserved.

    Three patients with transient episodes of hypotension following blunt abdominal trauma incurred in motor vehicle accidents were examined by computed tomography within 6 hours of injury. None of the patients had splenic injury evident on autopsy, surgery, or clinical follow-up study (one case each), nor did they have other characteristic features of splenic infarction. However, in each case the spleen was less enhanced than the liver, leading to an erroneous impression in one patient that the splenic artery had been disrupted. Physiologic studies have shown that splenic perfusion decreases with sympathetic stimulation; this may have been the cause of the diminished enhancement. Decreased splenic enhancement should be interpreted cautiously in traumatized hypotensive patients

    Partial splenic embolization (PSE) is a non-surgical procedure used to treat hypersplenism in various clinical settings and thus to avoid the disadvantages of splenectomy. PSE can be employed for the treatment of a variety of diseases including hypersplenism, thrombocytopenia, portal hypertension, splenic arterial aneurysms, etc. PSE can effectively relieve the splenic artery steal syndrome which occurred after liver transplantation, and therefore significantly improve the blood perfusion of the recipient liver. Besides, PSE can also be adopted to reduce the bleeding risk in patients with esophageal and gastric varices caused by portal hypertension. PSE is beneficial to the improvement of peripheral hematologic parameters, which helps the patients successfully undergo the high-dose chemotherapy or interferon therapy. In addition, PSE possesses potential curative effect for thrombocytopenia related diseases such as chronic idiopathic thrombocytopenic purpura. This paper aims to make a comprehensive review of the recent progress in the clinical application of partial splenic embolization. (authors)

    Purpose. To assess the feasibility and effectiveness of endovascular treatment of splenic artery aneurysm (SAAs). Materials and methods. Between May 2000 and June 2003 we treated 11 true SAAs in 9 patients (7 females and 2 males; mean age 58 years), 8 saccular and 3 fusiform, 4 located at the middle tract of the splenic artery, 5 at the distal tract and 2 intra-parenchymal. The diagnosis was performed with colour-Doppler ultrasound and/or CT-angiography; 7 patients were symptomless, 1 had left hypochondriac pain, and 1 had acute abdomen caused by a ruptured SAA. Four SAAs were treated by micro coil embolisation of the aneurysmal sac with preservation of splenic artery patency; in 2 cases this was associated with transcatheter injection of N-butyl-2-cyanoacrylate. Four cases were treated by endovascular ligature, with sectoral spleen ischaemia. One ruptured SAA received emergency treatment with splenic artery cyanoacrylate embolisation. Two intra-parenchymal SAAs were excluded, one by cyanoacrylate embolisation of the afferent artery and the other by transcatheter thrombin injection in the aneurysmal sac. Results. Technical success was observed in all cases (in 10/11 at the end of the procedure; in 1/11 at CT performed 3 days after the procedure). The follow-up (mean 18 months; range 6-36) was performed by colour-Doppler ultrasound and/or CT-angiography 3, 6 and 12 months after the procedure and subsequently once a year; the complete exclusion of the aneurysms was confirmed in 11/11 cases. The complications were: 4 cases of mild pleuritis; fever and left hypochondriac pain 1 day after the procedure (in the same 4 patients and in one other case); 5 cases of sectorial spleen ischaemia and 1 case of diffuse spleen infarction with partial revascularization by collateral vessels. No alteration of the levels of pancreatic enzymes was found; a transitory increase in platelet count occurred only in the patient with diffuse spleen infarction. Conclusions. Using different

    Objective: To report our experience of interventional procedure for arterial complications in post renal transplantation and to evaluate its clinical value. Methods: In a retrospective analysis of renal transplantations in our center, 52 cases of renal allograft artery abnormalities had taken angiography. Interventional procedure included transluminal angioplasty of arterial stenoses, treatment of arterial occlusion, and embolization of pseudoaneurysm. Results: Renal allograft artery abnormalities included artery stenosis (n=21), artery thrombosis (n=13) and embolision (n=1), renal artery pseudoaneurysms (n=2), and decrease of renal artery flow (n=3). Of the 21 artery stenosis, 2 grafts with artery stenosis were lost because the stenosis could not be corrected, and 3 with mild stenosis received no treatment. Another 16 accepted renal artery angioplasty (balloon dilation, n=12, and stent implantation, n=4). 14 achieved long-term allograft function. 1 graft was lost because renal function failed to recover. Restenosis occurred in one stent implantation, and lost the allograft function after secondary dilation. 13 cases received thrombolytic therapy through artery catheter for thrombosis and 9 achieved long-term allograft function. Thrombolyses failed in 3 cases, and renal function failed to recover in 1 case. One pseudoaneurysm received stent implantation after embolization, and got a short-term allograft function. The other one received allograft excision. Conclusion: Intravascular interventional therapy will be the first-line therapy for any indications of complication in post renal transplantation, and it can surely save the kidney in a majority of instances.

    Axillary pseudoaneurysm is a rare but important complication of anterior glenohumeral joint dislocation. Diagnosis of axillary pseudoaneurysm is predominantly undertaken following clinical examination but where diagnosis is uncertain, Doppler ultrasound is the imaging examination of choice to confirm diagnosis. In this case study, the initial clinical signs of axillary pseudoaneurysm were masked by the presenting trauma and, although findings indicative of pseudoaneurysm were present on late plain film images, they were not immediately recognised. Misdiagnosis or delayed diagnosis of axillary pseudoaneurysm may result in upper limb morbidity or patient mortality. Consequently, the prompt and accurate identification of an axillary pseudoaneurysm on plain film radiographs, although rare, is essential. Yet for inexperienced film readers, correctly identifying an axillary pseudoaneurysm can be difficult due to its apparent similarity to other pathologies. This article will highlight the differences in radiological appearances between a pseudoaneurysm and a gleno-humeral joint effusion to raise radiographer awareness of the risks and clinical signs of an axillary pseudoaneurysm post gleno-humeral joint dislocation and discuss the difficulties encountered in its diagnosis. Finally, this review will evaluate current diagnostic practices in comparison with best practice, as identified in the literature [Fitzgerald JF, Keates J. False aneurysm as a late complication of anterior shoulder dislocation. Ann Surg 1975;6:785-6; Drury JK, Scullion JE. Vascular complications of anterior dislocation of the shoulder.

    Identifying extra spinal causes of a lumbar radiculopathy or polyneuropathy can be a tricky diagnosis challenge, especially in children. Among them, traumatic or iatrogenic pseudoaneurysms of iliac arteries have been seldom reported, in adults' series. The authors report an unusual case of progressive paralyzing left sciatica and lumbar plexopathy in a 12 years old boy, 12 months after a pelvic osteotomy for bilateral hip luxation secondary to osteochondritis dissecans. Spine MRI and pelvic CT angiography revealed a giant internal iliac artery pseudoaneurysm, enclosed in a chronic hematoma. The patient was successfully treated with endovascular coil embolization, and subsequent surgical hematoma evacuation. However, three months after treatment, neurological recovery was incomplete. This case highlights the importance of a rapid and extensive diagnosis work up of all causes of lower limb radiculopathies in children, including pelvic arteries lesions especially after pelvic surgery to avoid therapeutic delays that may jeopardize the chances of neurological recovery.

    We describe concomitant Marfan syndrome and Takayasu's arteritis complicating a pseudoaneurysm of the left ventricular outflow that developed after aortic root reconstruction. A patient was admitted with a high fever four months after initial root reconstruction that included valve sparing (reimplantation) as well as coronary artery reconstruction using a Carrel's button technique. Computed tomography revealed a pseudoaneurysm at the posterior side of the aortic root. We applied a modified Bentall procedure including coronary artery reconstruction using the Piehler technique. Pathological assessment of a specimen of the aorta revealed no central medial necrosis, but significant lymphocytic infiltration and thick fibrous adventitia indicating Takayasu's arteritis. This case was unique in terms of having simultaneous Takayasu's arteritis and cardiovascular manifestations of Marfan syndrome that were surgically treated.

    Hemorrhage is an uncommon but serious complication of pancreatic pseudocysts. When gastrointestinal bleeding or intra-abdominal hemorrhage is associated with a pancreatic pseudocysts and the usual sources of bleeding are not detected by endoscopy, the rupture of a pseudoaneurysm inside the pseudocyst should be suspected. The article present 13 cases, 11 associated with chronic and 2 with late complications after acute necrotizing pancreatitis. On the basis of sonographic findings, bleeding site was suspected in 8 of 11 patients. Computed tomography (CT) was performed on 10, and bleeding was suspected in 8. The pseudoaneurysm itself was detected by CT in one and by ultrasonography in none. Visceral angiography was performed on five patients, and the pseudoaneurysm was evident in all. External drainage with arterial ligation was done as a primary operation in five patients; four of them later underwent pancreatic resection because of rebleeding. In eight cases pancreatic resection was the initial operation; none of these patients continued to bleed or needed reoperation because of the same pseudoaneurysm. There were no intraoperative deaths, but one patient died postoperatively. Aggressive diagnostic evaluation and surgical approach are associated with a reduction in mortality and morbidity in this serious complication of pancreatic pseudocysts. 28 refs., 2 figs., 1 tab

    Uterine, ovarian, and placental pathologies are among the differential considerations for a pregnant woman presenting with abdominal and pelvic pain. Imaging plays a key role in the initial work-up of these patients. Sonography is often the first line test; however, evaluation of pelvic pathology can be limited in the gravid state, especially in mid- or late-term pregnancy. We present a case of a pregnant woman who came to the emergency room at 25 weeks with acute abdominal and pelvic pain. Both ultrasound and MR imaging findings revealed intraperitoneal hemorrhage, initially of unknown origin, as well as endometriomas and deep endometriosis. Only postpartum imaging confirmed a uterine artery pseudoaneurysm (PSA) presumably due to decidual reaction in deep endometriosis. We speculate the intraperitoneal hemorrhage was subsequently due to the PSA. This case demonstrates that if hemorrhage is not recognized promptly, it can lead to hemodynamic instability, as well as premature labor and delivery.

    A 29-year-old woman (gravida 1, para 1) had an uneventful first pregnancy and a delivery by emergency caesarean section at term. The caesarean section was complicated by a massive obstetric haemorrhage of 5000 ml. After closure, an immediate re-laparotomy was indicated due to heavy vaginal bleeding. The site of bleeding was identified as an extension of the uterine incision, and was sutured. She was stabilised by transfusion of blood and blood products in the intensive therapy unit, and discharged 5 days later. The patient was re-admitted 6 weeks later with brisk, painless vaginal bleeding, passing large clots from a well-contracted uterus. Her haemoglobin decreased from 11.8 to 7.8 g/dl overnight. In view of her history, an urgent CT angiogram was performed, which revealed the presence of a pseudo-aneurysm arising from the left uterine artery. This was successfully occluded by transarterial embolisation, obviating the need for further surgical exploration.

    Full Text Available Arterial injury following impalement due to a trochanteric hip fracture-fragment per se has been documented rarely. We report a case of pseudoaneurysm of profunda femoris artery at the first perforator branch in a 48-year-old male, with trochanteric hip fracture following a fall during an epileptic episode. Persistent recalcitrant pain, globular swelling in the groin, unexplained drop in the haemoglobin level, and color doppler ultrasonography findings were salient features to the diagnosis. Additionally, we collected all reported cases of pseudoaneurysm associated with hip fractures. We reviewed the literature regarding the incidence, treatment, and prognosis for the same. Acute vascular injury was probably caused by the spikes of fractured lesser trochanter which was found to be displaced superomedially. All trochanteric fractures especially those with displaced lesser trochanter fragment should be closely watched for the possibility of vascular injury. Early diagnosis and treatment in a staged manner can prevent the catastrophic vascular event and hence the limb.

    The American Pediatric Surgical Association (APSA) advocates for the use of a clinical practice guideline to direct management of hemodynamically stable pediatric spleen injuries. The clinical practice guideline is based on the CT score of the spleen injury according to the American Association for the Surgery of Trauma (AAST) CT scoring system. To determine the potential effect of radiologist agreement for CT scoring of pediatric spleen injuries on an established APSA clinical practice guideline. We retrospectively analyzed blunt splenic injuries occurring in children from January 2007 to January 2012 at a single level 1 trauma center (n = 90). Abdominal CT exams performed at clinical presentation were reviewed by four radiologists who documented the following: (1) splenic injury grade (AAST system), (2) arterial extravasation and (3) pseudoaneurysm. Inter-rater agreement for AAST injury grade was assessed using the multi-rater Fleiss kappa and Kendall coefficient of concordance. Inter-rater agreement was assessed using weighted (AAST injury grade) or prevalence-adjusted bias-adjusted (binary measures) kappa statistics; 95% confidence intervals were calculated. We evaluated the hypothetical effect of radiologist disagreement on an established APSA clinical practice guideline. Inter-rater agreement was good for absolute AAST injury grade (kappa: 0.64 [0.59–0.69]) and excellent for relative AAST injury grade (Kendall w: 0.90). All radiologists agreed on the AAST grade in 52% of cases. Based on an established clinical practice guideline, radiologist disagreement could have changed the decision for intensive care management in 11% (10/90) of children, changed the length of hospital stay in 44% (40/90), and changed the time to return to normal activity in 44% (40/90). Radiologist agreement when assigning splenic AAST injury grades is less than perfect, and disagreements have the potential to change management in a substantial number of pediatric patients.

Inter-rater agreement was assessed using weighted (AAST injury grade) or prevalence-adjusted bias-adjusted (binary measures) kappa statistics; 95% confidence intervals were calculated. We evaluated the hypothetical effect of radiologist disagreement on an established APSA clinical practice guideline. Inter-rater agreement was good for absolute AAST injury grade (kappa: 0.64 [0.59-0.69]) and excellent for relative AAST injury grade (Kendall w: 0.90). All radiologists agreed on the AAST grade in 52% of cases. Based on an established clinical practice guideline, radiologist disagreement could have changed the decision for intensive care management in 11% (10/90) of children, changed the length of hospital stay in 44% (40/90), and changed the time to return to normal activity in 44% (40/90). Radiologist agreement when assigning splenic AAST injury grades is less than perfect, and disagreements have the potential to change management in a substantial number of pediatric patients. (orig.)

    The American Pediatric Surgical Association (APSA) advocates for the use of a clinical practice guideline to direct management of hemodynamically stable pediatric spleen injuries. The clinical practice guideline is based on the CT score of the spleen injury according to the American Association for the Surgery of Trauma (AAST) CT scoring system. To determine the potential effect of radiologist agreement for CT scoring of pediatric spleen injuries on an established APSA clinical practice guideline. We retrospectively analyzed blunt splenic injuries occurring in children from January 2007 to January 2012 at a single level 1 trauma center (n = 90). Abdominal CT exams performed at clinical presentation were reviewed by four radiologists who documented the following: (1) splenic injury grade (AAST system), (2) arterial extravasation and (3) pseudoaneurysm. Inter-rater agreement for AAST injury grade was assessed using the multi-rater Fleiss kappa and Kendall coefficient of concordance. Inter-rater agreement was assessed using weighted (AAST injury grade) or prevalence-adjusted bias-adjusted (binary measures) kappa statistics; 95% confidence intervals were calculated.

    Splenic artery embolization (SAE) improves non-operative splenic salvage rates in adults, but its utility and safety in the pediatric population is less well defined. Because adolescent trauma patients are often triaged to adult trauma centers, we were interested in evaluating SAE in this particular population. We hypothesize that angiography and embolization is a safe and effective adjunct to non-operative management in the adolescent population. A retrospective review of all patients aged 13-17 years admitted to our Level I Trauma Center with blunt splenic injury from 1997-2005 was performed. We reviewed patient demographics, operative reports, admission, and follow-up abdominal computed tomography (ACT) results, angiographic reports, and patient outcomes. A total of 97 patients were reviewed. Eighteen patients underwent immediate surgery, and 79 of the remaining patients had planned non-operative management. Of those participating in non-operative management, 35/79 (44%) were initially observed and 44/79 (56%) underwent initial angiography, 23/44 having embolization. Patients in the embolization group had an overall high grade of injury (American Association for the Surgery of Trauma mean grade 3.3, SD 0.6). The overall splenic salvage rate was 96% (76/79) in the non-operative management group; 100% splenic salvage was seen in the observational group; 100% salvage was also seen in patients with negative angiography, and 87% salvage (20/23) in the splenic artery embolization group. Splenic artery embolization may be a valuable adjunct in adolescent blunt splenic injury, especially in higher grade injuries or with evidence of splenic vascular injury on ACT.

    Full Text Available Introduction: Non-operative management (NOM of splenic trauma in children is currently the treatment of choice. Purpose: We report a series of 83 cases in order to compare our results with literature data. Patients and Methods: For this, we conducted a retrospective study of 13 years and collected 83 cases of children with splenic trauma contusion, managed at Lapeyronie Montpellier Hospital in Visceral Pediatric Surgery Department. The studied parameters were age, sex, circumstances, the blood pressure (BP, hematology, imaging, associated injuries, transfusion requirements, treatment, duration of hospital stay, physical activity restriction and evolution. Results: NOM was successful in 98.7% of cases. We noted 4 complications including 3 pseudo aneurysms (PSA of splenic artery and 1 pseudocyst spleen with a good prognosis. There was no mortality in our series. Conclusion: NOM is the treatment of choice for splenic trauma in children with a success rate of over 90%. Complications are rare and are dominated by the PSA of splenic artery.

    Full Text Available Six male patients (age group: 30-60 years with aneurysm of the splenic artery presented with massive upper gastrointestinal tract hemorrhage. Five patients presented with hematemesis and one with melena. Chronic pancreatitis was noted in all the patients, four of whom were chronic alcoholics. Endoscopy was not useful in diagnosis. Bleeding through the Ampulla of Vater was seen in the patient with melena. Angiography was diagnostic in all. Pancreatic resection including the aneurysm(2, and bipolar ligation with underrunning of the aneurysm (3 were the operative procedures. Distal pancreatectomy with pancreatogastrostomy was carried out in the patient with hemosuccus pancreaticus. If endoscopy is inconclusive, angiography and early intervention is recommended to reduce the high mortality associated with conservative management.

    Whiplash trauma from a car crash is one of the most common causes of neck injury, resulting in pain and dysfunction. We report on an unusual case of post-whiplash pseudoaneurysm of the right common carotid artery, which led to acute massive hemorrhage and death days after the initial trauma. A post-mortem computed tomography angiography showed rupture of the pseudoaneurysm of the right common carotid artery with the contrast agent leaking out into the mouth. The subsequent autopsy confirmed a large hemorrhagic clot extending to the right side of the neck and mediastinum. A rupture of the right wall of the oropharynx was identified with massive bronchial hemoaspiration. The case demonstrates a rare but lethal clinical entity, and is important in providing a better understanding of the potentially fatal consequences of minor trauma, such as whiplash injury, and its physiopathological mechanisms. Thus, changing symptoms after a whiplash injury should be carefully evaluated since they can be related to the underlying severe consequences of a rapid hyperextension-hyperflexion of the neck, as in the reported case.

    Objective: To explore the role of endovascular techniques in treatment for arterial injuries of skull base. Methods: A total of 53 consecutive cases suffered from skull base arterial injuries were enrolled in our hospital from Oct 2004 to May 2007, including 44 male and 9 female cases with average age of 23.3 years. Thirty-nine cases presented with pulsatile exophthalmos and intracranial vascular murmur, cerchnus and dysphagia in another 9, epistaxis in the remaining 5 cases. Diagnosis of 39 carotid cavernous fistulae (CCF)and 14 carotid pseudoaneurysm were performed by angiography (DSA). Alternative endovascular procedures were performed depending on lesions characteristics and follow-up was done by telephone and outpatient work up. Results: Procedures were performed involving 56 carotid arteries in all 53 cases including 34 CCF with embolization of detachable balloon(33 cases), 3 with balloon and coils, and 3 by stent-graft placement. 8 carotid pseudoaneurysms were cured by parent artery occlusion with balloon, 2 experienced endovascular isolation with balloon and coils, and 4 with stent-graft. Follow-up for mean 9.5 months (range from 2 to 25 months) revealed that the chief symptoms of 45 cases (85%) were relieved within 6 months after the procedure but ocular movement and visual disorder remained in 8 cases (15%)till 12 months. Six pseudoaneurysms and 3 residual leak were found in reexamination, of which 2 cases underwent intervention again 2 and 3 months later due to dural arterial-venous fistula in cavernous sinus, respectively. Conclusions: Endovascular treatment is safe and effective therapeutic option with minimal invasion for skull base arterial injuries. Detachable balloon embolization is the first choice for CCF and carotid pseudoaneurysm. Spring coil packing and stent-graft implantation should be in alternation as combination for special cases.

    Uterine artery pseudoaneurysms (UAP) are rare but potentially life-threatening lesions. They may occur after traumatic deliveries, cesarean sections, and other interventions. We present a case of a 39-year-old woman with a UAP. The patient was accurately diagnosed using ultrasound imaging, with subsequent diagnostic hysteroscopy and laparoscopic excision of the UAP. In the present case, a ligation of the artery branch was performed to provide accurate hemostasis during UAP dissection. The vascular lesion was partially enucleated and removed, followed by recreation of the previous uterine shape. Power Doppler with HD flow and 3D ultrasound are accurate methods in the diagnosis of UAP. We are of the opinion that laparoscopic surgery can be on a par with transarterial embolization. During laparoscopy, the surgeon can either close the feeding vessel or remove the pathological tissue. In our opinion, this method solves the problem permanently and, after a successful case series with long-term follow-up, might be applied in other centers as well.

    A 62-year-old man presented with rupture of a pseudoaneurysm of the left common carotid artery (CCA) that was induced after radiation therapy and neck surgery. The initial treatment was an endovascular procedure to obliterate the aneurysm with coils, and a covered stent was placed in the parent artery. However, the patient presented with subsequent coil migration, wound infection, and left CCA stenosis. Direct surgical procedures were then performed, including resection of the pseudoaneurysm with coils and stent; replacement of the carotid artery with a saphenous vein graft; and operative wound reinforcement with a pedicle flap. Endovascular treatments may be chosen for vascular diseases after irradiation, because of the low risk of wound infection and fragility of the vessels, but the long-term outcomes of intravascular treatments are still unclear. In direct surgery, dissection of the adhesive tissue and adequate wound healing are difficult. Musculocutaneous flaps with vascular pedicles can achieve good results. (author)

    We describe concomitant Marfan syndrome and Takayasu’s arteritis complicating a pseudoaneurysm of the left ventricular outflow that developed after aortic root reconstruction. A patient was admitted with a high fever four months after initial root reconstruction that included valve sparing (reimplantation) as well as coronary artery reconstruction using a Carrel’s button technique. Computed tomography revealed a pseudoaneurysm at the posterior side of the aortic root. We applied a modified Bentall procedure including coronary artery reconstruction using the Piehler technique. Pathological assessment of a specimen of the aorta revealed no central medial necrosis, but significant lymphocytic infiltration and thick fibrous adventitia indicating Takayasu’s arteritis. This case was unique in terms of having simultaneous Takayasu’s arteritis and cardiovascular manifestations of Marfan syndrome that were surgically treated. PMID:23555475

    Full Text Available Hematomas caused by surgery or trauma that persist and expand slowly for more than a month are defined as chronic expanding hematomas (CEH. Magnetic resonance imaging (MRI is useful for the diagnosis. Total excision with the pseudocapsule is the treatment method. Pseudoaneurysms result from arterial wall disruptions and can be mistaken for CEH. We present a rare case report of a 45-year-old man with a large, painful swelling in his left popliteal fossa. He had a puncture wound by a nail 11 years ago and a gradually expanding mass occurred in his popliteal fossa. A pseudoaneurysm was detected and operated a year later. After surgery, a gradually expanding mass recurred in his popliteal fossa. On the arteriography, the popliteal artery was occluded and the blood flow was maintained with collateral vessels. On MRI, an enormous swelling of 115 × 107 × 196 cm in diameter was seen. It was diagnosed as CEH and was excised completely protecting the collateral vessels and there was no recurrence after a year from the surgery.

    Purpose: The effectiveness of angiography and embolization in diagnosis and treatment were assessed in a cohort of patients presenting with upper gastrointestinal hemorrhage secondary to hepatic artery pseudoaneurysm following laparoscopic cholecystectomy. Methods: Over a 6-year period 1513 laparoscopic cholecystectomies were carried out in our region. Nine of these patients (0.6%) developed significant upper gastrointestinal bleeding, 5-43 days after surgery. All underwent emergency celiac and selective right hepatic artery angiography. All were treated by coil embolization of the right hepatic artery proximal and distal to the bleeding point. Results: Pseudoaneurysms of the hepatic artery adjacent to cholecystectomy clips were demonstrated in all nine patients at selective right hepatic angiography. In three patients celiac axis angiography alone failed to demonstrate the pseudoaneurysm. Embolization controlled hemorrhage in all patients with no further bleeding and no further intervention. One patient developed a candidal liver abscess in the post-procedure period. All patients are alive and well at follow-up. Conclusion: Selective right hepatic angiography is vital in the diagnosis of upper gastrointestinal hemorrhage following laparoscopic cholecystectomy. Embolization offers the advantage of minimally invasive treatment in unstable patients, does not disrupt recent biliary reconstruction, allows distal as well as proximal control of the hepatic artery, and is an effective treatment for this potentially life-threatening complication

    Normal young piglets and miniature piglets of the Gottingen breed were used as animal models for autotransplantation of splenic fragments. In pigs, regeneration kinetics seem to be comparable to man. Even after six mo, only small splenic nodules with a reduced blood flow were found. No effective stimulator of splenic regeneration has been found for pigs. Pig spleen size and blood supply enable partial splenectomies and ligation of the splenic artery which are models for spleen surgery in man

    A 13-month-old boy with Gaucher disease presented with severe thrombocytopenia, anemia and massive splenomegaly. In addition he had significant respiratory compromise caused by abdominal compartment syndrome, requiring mechanical ventilation. Because of the degree of respiratory compromise and his existing bone marrow suppression, splenic artery embolization was chosen as an alternative to splenectomy. Splenic artery embolization was performed using 355-500-μm polyvinyl alcohol particles, with 70% ablation achieved. Within 24 h of the procedure the platelet count had risen to greater than 70,000/mm 3 and to more than 170,000/mm 3 on postoperative day 4. At the 8-month follow-up the splenic size had decreased from 18 cm to 8 cm, with a platelet count of 578,000/mm 3 . Partial splenic embolization provides a minimally invasive alternative to splenectomy in patients with Gaucher disease with massive splenomegaly and bone marrow suppression. (orig.)

    Extended Whipple procedures may require division of the splenic vein (SV). Controversy exists regarding the risk of sequelae of sinistral portal hypertension when the SV is ligated without reimplantation. The aim of this study was to identify postoperative venous collateral patterns and sequelae of SV ligation, as well as long-term results in an extended Whipple procedure. Patients who had an extended Whipple procedure (Whipple at the Splenic Artery or WATSA) were entered in an institutional database. Evaluation of the venous collaterals was performed at least 5 months postoperatively by imaging. Spleen size and platelet counts were measured before and after operation. Fifteen patients were entered from 2009 to 2014. SV was not reconstructed and the IMV-SV junction was always resected. Two collateral routes developed. An inferior route was present 14/15 patients. It connected the residual SV to the SMV via intermediate collateral veins in the omentum and along the colon. A superior route, present in 10/15 patients connected the residual SV to the portal vein via gastric, perigastric, and coronary veins. Gastrointestinal bleeding did not occur. Mean platelet count and spleen size were not affected significantly. Procedures were long, but few severe complications developed. In 12 patients with adenocarcinoma, the median survival has not been reached. Patients who have SV ligation in an extended Whipple are protected against sequelae of sinestral portal hypertension by inferior collateral routes. The omentum and marginal veins of the colon are key links in this pathway.

    Objective: The aim of this study was to compare the value of contrast-enhanced ultrasonography (CEUS) with standard B-mode ultrasound (US) for diagnosis of splenic lymphoma involvement. Methods: From 04/2005 to 10/2008 n = 250 lymphoma patients were investigated by standard B-mode US. A homogeneous splenic echotexture was found in 199 patients (79%). To clarify the benefit of CEUS in this group a pilot series was performed with 16 of the 199 lymphoma patients. All patients with an abnormal splenic echotexture on standard B-Mode US (n = 51) including focal hypoechoic splenic lesions (n = 41) and an inhomogeneous splenic texture (n = 10) were studied by CEUS. CEUS data were retrospectively evaluated. The diagnoses included indolent lymphoma (n = 27), aggressive lymphoma (n = 14), and Hodgkin's disease (n = 10). Number and size of lesions were determined by B-mode US and CEUS. The visualisation of splenic lymphoma involvement by CEUS in comparison to B-mode US was classified as worse, equal, or better. Results: All patients with a homogeneous spleen on B-mode US (n = 16) had no visible focal lesions on CEUS. Study patients with focal lesions (n = 41) had a hypoechoic (n = 22) or isoechoic (n = 19) enhancement during the arterial phase, and a hypoechoic enhancement during the parenchymal phase (n = 41). The visualisation of focal splenic lymphoma was equal (n = 32), better (n = 6), or worse (n = 3). In all study patients with an inhomogeneous spleen on B-mode US (n = 10) no focal lesions were found by CEUS and the value of CEUS therefore was classified as worse. Conclusion: CEUS has no clear advantage for diagnosis of splenic lymphoma involvement.

  1. Pseudoaneurysm Accompanied by Crowe Type IV Developmental Dysplasia of the Hip: A Case Report

    Directory of Open Access Journals (Sweden)

    Hirotake Yo

    2012-01-01

    Full Text Available We report the case of a 72-year-old woman whose pseudoaneurysm was difficult to diagnose and treat. The patient had a history of congenital dislocated hip and was undergoing anticoagulation therapy with warfarin due to the mitral valve replacement. Her chief complaint was pain and enlargement of the left buttock, and the laboratory tests revealed severe anemia. However, her elderly depression confused her chief complaint, and she was transferred to a psychiatric hospital. Two months after the onset of the symptoms, she was finally diagnosed with a pseudoaneurysm by contrast-enhanced CT and angiography. IDC coils were used for embolization. A plain CT showed hemostasis as well as a reduced hematoma at 2 months after the embolization. The possible contributing factors for the pseudoaneurysm included bleeding due to warfarin combined with an intramuscular hematoma accompanied by Crowe type IV developmental dysplasia of the hip that led to an arterial rupture by impingement between pelvis and femoral head. Since the warfarin treatment could not be halted due to the valve replacement, embolization was chosen for her treatment, and the treatment outcome was favorable.

    The incidence of splenectomy after trauma is institutionally dependent and varies from 18% to as much as 40%. This is important because variation in management influences splenic salvage. The aim of this study was to investigate whether differences exist between Dutch level 1 trauma centers with respect to the treatment of these injuries, and if variation in treatment was related to splenic salvage, spleen-related reinterventions, and mortality. Consecutive adult patients who were admitted between January 2009 and December 2012 to five academic level 1 trauma centers were identified. Multinomial logistic regression was used to measure the influence of hospital on treatment strategy, controlling for hemodynamic instability on admission, high grade (American Association for the Surgery of Trauma 3-5) splenic injury, and injury severity score. Binary logistic regression was used to quantify differences among hospitals in splenic salvage rate. A total of 253 patients were included: 149 (59%) were observed, 57 (23%) were treated with splenic artery embolization and 47 (19%) were operated. The observation rate was comparable in all hospitals. Splenic artery embolization and surgery rates varied from 9%-32% and 8%-28%, respectively. After adjustment, the odds of operative management were significantly higher in one hospital compared with the reference hospital (adjusted odds ratio 4.98 [1.02-24.44]). The odds of splenic salvage were significantly lower in another hospital compared with the reference hospital (adjusted odds ratio 0.20 [0.03-1.32]). Although observation rates were comparable among the academic trauma centers, embolization and surgery rates varied. A nearly 5-fold increase in the odds of operative management was observed in one hospital, and another hospital had significantly lower odds of splenic salvage. The development of a national guideline is recommended to minimalize splenectomy after trauma. Copyright © 2015 Elsevier Inc. All rights reserved.

    PurposeExplore the application of endovascular covered stent-graft (SG) placement in femoral pseudoaneurysms in intravenous drug addicts.Materials and MethodsWe evaluated a consecutive series of pseudoaneurysm in intravenous drug addicts treated with SGs from August 2010 to December 2013.Results15 patients with 16 arterial pseudoaneurysms were enrolled in this study. All were males with a mean age of 36.9 years. Hemorrhage was the most common reason (93.8 %) for seeking medical care, and 3 of these patients were in hemorrhagic shock at admission. All patients received broad-spectrum antibiotics, and debridement and drainage were implemented after SG placement. 7 of the 13 cases which had microbiologic results showed mixed infections, while gram-negative bacteria were the major pathogens. Except for 2 patients, who were lost to follow-up, two new pseudoaneurysms formed due to delayed debridement, and one stent thrombosis occurred, none of the remaining cases had SG infection or developed claudication.ConclusionsSG placement controls massive hemorrhage rapidly, gives enough time for subsequent treatment for pseudoaneurysms due to intravenous drug abuse, and reduces the incidence of postoperative claudication. With appropriate broad-spectrum antibiotics and early debridement, the incidence of SG infection is relatively low. It is an effective alternative especially as temporary bridge measure for critical patients. However, the high cost, uncertain long-term prospects, high demand for medical adherence, and the risk of using the conduits for re-puncture call for a cautious selection of patients.

    A 71-year-old woman presented with a life-threatening thyroid hemorrhage after US-guided chemical parathyroidectomy. The diagnosis was made by angiography followed by immediate embolization of a pseudoaneurysm of the left superior thyroid artery. Embolization controlled the hemorrhage, obviating the need for surgery. The patient made a full recovery with no evidence of further hemorrhage. Pseudoaneurysm of the superior thyroid artery is a rare cause of hemorrhage and percutaneous embolization is an effective method of treatment

    Full text: Introduction: Abdominal aortic pseudoaneurysms are rare and life-threatening situations. Trauma and operative procedures are common causes of pseudoaneurysm. Abdominal pain is the most common symptom of them. They are usually detected incidentally. Objectives and tasks: We aim to present CTA findings of abdominal aortic pseudoaneurysm causes gradually increasing lomber pain in 70-year-old female patient. Physical examination also made diagnosis easy because of pulsatile mass detected. Materials and methods: Lomber MRG and endoscopic procedures were normal. Then we performed CTA to find the cause for pulsatile mass. Results: Pseudoaneurysm with approximately 6 x 7.5 cm size was compressing duodenum and not showing extravasation at the infrarenal segment of abdominal aorta detected in CTA. Pseudoaneurysm was filling from aorta through a 2 cm neck. Conclusion: Primary cause for pseudoaneurysms is traumating injuries. Initial presentation may be abdominal pain, gastrointestinal bleeding or pulsatile mass. To plan treatment and figure out pseudoaneurysm CTA is very fast and non-invasive technic

    Purpose: Thrombin injection is becoming well established for the percutaneous management of iatrogenic pseudoaneurysms. All the published series to date use bovine thrombin,and there have been reports of adverse immunologic effects following its use. Our study aimed to assess the efficacy of human thrombin injection for pseudoaneurysm occlusion. Methods:Fourteen patients with iatrogenic pseudoaneurysms underwent a color Doppler ultrasound examination to assess their suitability for percutaneous human thrombin injection. Human thrombin 1000 IU was then injected into the pseudoaneurysm sac under sterile conditions and with ultrasound guidance. A further color Doppler ultrasound examination was performed 24 hr later to confirm occlusion. Results: All 14 pseudoaneurysms were successfully occluded by human thrombin injection. In two cases a second injection of thrombin was required,but there were no other complications, and all pseudoaneurysms remained occluded at 24 hr. Conclusion: Ultrasound-guided human thrombin injection is simple to perform, effective and safe. We recommend that human thrombin becomes the agent of choice for percutaneous injection into iatrogenic pseudoaneurysms

    Over the last four years the authors performed transcatheter embolization of the splenic artery by Gianturco coils in 32 consecutive cirrhotic patients with portal hypertension, splenomegaly, cytopenia and gastro-esophageal varices endoscopically proved. This procedure was especially useful for treatement of splenomegaly and cytopenia because a constant reduction of spleen dimensions and increase in platelet count were registered. The effectiveness of transcatheter embolization and follow-up are based on clinic, hematologic and sonographic findings. Sonographic monitoring is believed to be very useful both to evaluate splenomegaly and signs of portal hypertension and to reveal splenic complications (abscesses). Severe complications have been never registered

    The aim of this study is the presentation of the hepatic and splenic radionuclide angiograms (SRA) in various portal blood flow disturbances, as well as an analysis of the splenic arterio-venous ratio (SAVR) results, obtained as a slope ratio between inflow, arterial and the outflow, venous phases on the splenic TA curve. Splenic radionuclide angiography was performed after bolus injection of 740 MBq of 99m-Tc-pertechnetate, using ROTA scintillation camera (Siemens) and MicroDelta computer'. Four types of the SRA were established: a) very acute descendent slope (DS) in the controls; b) less acute DS in the patients with LC; c) horisontal venous phase caused by impaired outflow to the portal vein in LC with expressed portal hypertension, collateral circulation and LCEV; d) ascending outflow phase, characterizing the splenic and/or portal venous thrombosis. SAVR values were increased in liver cirrhosis (LC) with esophageal vahces (LCEV, n=10) (6.1 +/- 3.4) in comparison to the controls (n=10)(3.7 +/- 1.3)(U=25, p 0.05). However, in another two patients with LC and in 8 with LCEV it was not possible to access SAVR because of the appearance of the horisontal or rising venous phase on the splenic TA curve, instead of descendent. SRA and increased SAVR values reflect various blood flow alterations in the portal system and give additional data to the more accurate interpretation of the results obtained by hepatic radionuclide angiography.

    Management of postcatheterization femoral artery pseudoaneurysm (FAP) is problematic. Ultrasound-guided compression (UGC) is painful and cumbersome. Thrombin injection is costly and may cause thromboembolism. Ultrasound-guided para-aneurysmal saline injection (PASI) has been described but was never compared against other treatment methods of FAP. We aimed at comparing the success rate and complications of PASI versus UGC. We randomly assigned 80 patients with postcatheterization FAPs to either UGC (40 patients) or PASI (40 patients). We compared the 2 procedures regarding successful obliteration of the FAP, incidence of vasovagal attacks, procedure time, discontinuation of antiplatelet and/or anticoagulants, and the Doppler waveform in the ipsilateral pedal arteries at the end of the procedure. There was no significant difference between patients in both groups regarding clinical and vascular duplex data. The mean durations of UGC and PASI procedures were 58.14 ± 28.45 and 30.33 ± 8.56 minutes, respectively (p = 0.045). Vasovagal attacks were reported in 10 (25%) and 2 patients (5%) treated with UGC and PASI, respectively (p = 0.05). All patients in both groups had triphasic Doppler waveform in the infrapopliteal arteries before and after the procedure. The primary and final success rates were 75%, 92.5%, 87.5%, and 95% for UGC and PASI, respectively (p = 0.43). In successfully treated patients, there was no reperfusion of the FAP in the follow-up studies (days 1 and 7) in both groups. In conclusion, ultrasound-guided PASI is an effective method for the treatment of FAP. Compared with UGC, PASI is faster, less likely to cause vasovagal reactions, and can be more convenient to patients and physicians. Copyright © 2014 Elsevier Inc. All rights reserved.

    Nonoperative management (NOM) of blunt splenic injury, initially touted for the care of pediatric patients, has become the standard of care for stable trauma patients of all ages. In our institution, trauma patients younger than 16 years are managed by the pediatric surgery service and patients 16 years or older are managed by the adult trauma service. Angioembolization is routinely used for adults with blunt splenic injury but rarely used for pediatric patients. A retrospective chart review was performed to determine if more liberal use of angioembolization increases the success rate of NOM of blunt splenic injury in adolescents. Using our institutional trauma registry, we performed a retrospective chart review of 13- to 18-year-olds admitted with blunt splenic injury from 2007 to 2015. One hundred thirty-three patients were identified; 59 were 13- to 15-year-olds and cared for by the Pediatric Trauma service, whereas 74 were 16- to 18-year-olds and cared for by the Adult Trauma service. The cohorts were compared with respect to imaging performed, grade of injury, Injury Severity Score, presence of active extravasation or pseudoaneurysm, interventions performed, blood transfused, intensive care unit days, length of stay, complications, and 30-day mortality rates. There were no significant differences in Injury Severity Score, incidence of active extravasation or pseudoaneurysm identified on computed tomography, or grade of injury between the two cohorts. More patients underwent angioembolization in the "adult" group (p = 0.001) with no difference in the success rate of NOM (p = 0.117). The overall failure rate of NOM of high-grade injuries was only 4.1%. Failure of NOM in high-grade injuries is rare; as a result, the number needed to treat with prophylactic angioembolization would be around 37 patients, resulting in undue risk to many patients with no therapeutic benefit. No improvement in failure rate was seen with aggressive angioembolization, though a larger

    Pseudoaneurysms secondary to pancreatitis are uncommon but are associated with high rates of morbidity and mortality and thus, should bi diagnosed as early as possible. We present two cases of pseudoaneurysm diagnosed in our hospital in a series of 660 patients who were admitted for treatment of pancreatitis between 1991 and 1994. We show the radiologic images, correlating them with the surgical findings and we compare them with those reported in the literature. We also stress the importance of radiology (ultrasonography, computed tomography and angiography) in the early diagnosis of pseudoaneurysms. (Author) 9 refs

    To evaluate the onset and duration of hematological changes and the use of Doppler ultrasound (spleen) in dogs sedated with acepromazine or xylazine. Clinical study. A total of 24 mixed breed dogs aged 1-4 years and weighing 15-25 kg. Dogs were randomly distributed into two groups: acepromazine group (AG) which were administered acepromazine (0.05 mg kg -1 ) intramuscularly and xylazine group (XG) administered xylazine (0.5 mg kg -1 ) intramuscularly. Sonographic evaluations (morphologic and hemodynamic splenic vascularization) and hematologic tests were performed before drug administration (baseline) and 5, 15, 30, 60, 120, 240, 360, 480 and 720 minutes after drug administration. A significant reduction occurred in erythrogram variables in AG at 15-720 minutes corresponding with a significant enlargement of the spleen. In XG, a significant reduction was observed in the erythrogram variables at 30-60 minutes without a significant enlargement of the spleen. Hilar diameter did not change over time in either group. Flow alterations were found only in the splenic artery in AG, with a decreased final diastolic velocity observed at 60-120 minutes. Administration of acepromazine resulted in decreased red blood cell count, hemoglobin, packed cell volume and an increased diameter of the spleen. Xylazine administration resulted in similar hematologic changes but of smaller magnitude and duration and without splenic changes. The absence of significant changes in the Doppler flow parameters of the splenic artery and vein and the hilar diameter suggests that the splenomegaly that was observed in AG was not due to splenic vasodilation. No splenic sequestration occurred after xylazine administration. The results indicate that acepromazine decreases the erythrocyte concentrations by splenic erythrocyte sequestration and concomitant splenomegaly. Xylazine can cause slight hematologic changes, but without splenic changes. Copyright © 2017 Association of Veterinary

    Purpose: To evaluate the efficacy of estimating the volume of spleen embolized in partial splenic embolization (PSE) by measuring the diameters of the splenic artery and its branches. Materials and methods: A total of 43 liver cirrhosis patients (mean age, 62.19 ± 9.65 years) with thrombocytopenia were included. Among these, 24 patients underwent a follow-up CT scan which showed a correlation between angiographic estimation and measured embolized splenic volume. Estimated splenic embolization volume was calculated by a method based on diameters of the splenic artery and its branches. The diameters of each of the splenic arteries and branches were measured via 2D angiographic images. Embolization was performed with gelatin sponges. Patients underwent follow-up with serial measurement of blood counts and liver function tests. The actual volume of embolized spleen was determined by computed tomography (CT) measuring the volumes of embolized and non-embolized spleen two months after PSE. Results: PSE was performed without immediate major complications. The mean WBC count significantly increased from 3.81 ± 1.69 × 10 3 /mm 3 before PSE to 8.56 ± 3.14 × 10 3 /mm 3 at 1 week after PSE (P < 0.001). Mean platelet count significantly increased from 62.00 ± 22.62 × 10 3 /mm 3 before PSE to 95.40 ± 46.29 × 10 3 /mm 3 1 week after PSE (P < 0.001). The measured embolization ratio was positively correlated with estimated embolization ratio (Spearman's rho [ρ] = 0.687, P < 0.001). The mean difference between the actual embolization ratio and the estimated embolization ratio was 16.16 ± 8.96%. Conclusions: The method provides a simple method to quantitatively estimate embolized splenic volume with a correlation of measured embolization ratio to estimated embolization ratio of Spearman's ρ = 0.687

    Purpose: To evaluate the therapeutic role of angiography in patients with pseudoaneurysms complicating pancreatitis. Methods: Thirteen symptomatic pseudoaneurysms were treated in nine patients with pancreatitis. Eight patients had chronic pancreatitis and pseudocyst and one had acute pancreatitis. Clinical presentation included gastrointestinal bleeding in seven patients and epigastric pain without bleeding in two. All patients underwent transcatheter embolization. Results: Transcatheter embolization resulted in symptomatic resolution in all patients. Rebleeding occurred in two patients, 18 and 28 days after embolization respectively, and was successfully treated by repeated emnbolization. One patient with severe pancreatitis died from sepsis 28 days after embolization. Follow-up was then available for eight patients with no relapse of bleeding after a mean follow-up of 32 months (range 9-48 months). Conclusion: Transcatheter embolization is safe and effective in the management of pseudoaneurysms complicating pancreatitis

    Short gastric vessels are divided during the laparoscopic Nissen fundoplication resulting in splenic infarct in some cases. We report a case of laparoscopic floppy Nissen fundoplication with splenic infarct that was recognized during the procedure and provide a brief literature review. The patient underwent a laparoscopic floppy Nissen fundoplication. We observed a partial infarction of the spleen. She reported no pain. A follow-up computed tomography scan showed an infarct, and a 3-month abdominal ultrasound showed complete resolution. Peripheral splenic arterial branches have very little collateral circulation. When these vessels are occluded or injured, an area of infarction will occur immediately. Management strategies included a trial of conservative management and splenectomy for persistent symptoms or complications resulting from splenic infarct. In conclusion, we believe that the real incidence is probably much higher because many cases of SI may have gone undiagnosed during or following an operation, because some patients are asymptomatic. We propose to check spleen carefully for the possibility of splenic infarct. PMID:24833155

    There is no controlled study for the best treatment or management of cervico-cerebral artery dissection (CAD). Rationale initial empiric treatment in acute CAD to prevent secondary embolism is partial thromboplastin time (PTT)-guided anticoagulation by intravenous heparin followed by anticoagulation with warfarin. Carotid surgery for treatment of CAD is not recommended anymore with the possible exception of persisting severe stenosis of the proximal internal carotid artery (ICA). There could be use of carotid angioplasty by balloon dilatation and stenting in selected cases of severe cerebral hemodynamic impairment by bilateral CAD. Duration of secondary prophylaxis by anticoagulation is best guided by Doppler sonography follow-up, and should be continued until normalization of blood flow or until at least 1 year after the vessel is occluded. There is no evidence that pseudoaneurysms increase the risk for embolic complication, and there is no evidence for surgery or continuation of anticoagulation in patients with pseudoaneurysms. Caution should be recommended for exercises that involve excessive head movements (eg, bungee jumping, trampoline jumping, and chiropractic maneuvers). The patient should be informed that recurrent rate is low in nonfamilial cases. Doppler sonography is a low-cost and high-sensitivity method for patients at risk.

    BACKGROUND Splenic injury is the leading cause of major bleeding after blunt abdominal trauma. We examined the clinical and radiological presentations, management, and outcome of blunt splenic injuries (BSI) in our institution. MATERIAL AND METHODS A retrospective study of BSI patients between 2011 and 2014 was conducted. We analyzed and compared management and outcome of different splenic injury grades in trauma patients. RESULTS A total of 191 BSI patients were identified with a mean (SD) age of 26.9 years (13.1); 164 (85.9%) were males. Traffic-related accident was the main mechanism of injury. Splenic contusion and hematoma (77.2%) was the most frequent finding on initial computerized tomography (CT) scans, followed by shattered spleen (11.1%), blush (11.1%), and devascularization (0.6%). Repeated CT scan revealed 3 patients with pseudoaneurysm who underwent angioembolization. Nearly a quarter of patients were managed surgically. Non-operative management failed in 1 patient who underwent splenectomy. Patients with grade V injury presented with higher mean ISS and abdominal AIS, required frequent blood transfusion, and were more likely to be FAST-positive (p=0.001). The majority of low-grade (I-III) splenic injuries were treated conservatively, while patients with high-grade (IV and V) BSI frequently required splenectomy (p=0.001). Adults were more likely to have grade I, II, and V BSI, blood transfusion, and prolonged ICU stay as compared to pediatric BSI patients. The overall mortality rate was 7.9%, which is mainly association with traumatic brain injury and hemorrhagic shock; half of the deaths occurred within the first day after injury. CONCLUSIONS Most BSI patients had grade I-III injuries that were successfully treated non-operatively, with a low failure rate. The severity of injury and presence of associated lesions should be carefully considered in developing the management plan. Thorough clinical assessment and CT scan evaluation are crucial for

    Arterial supply to the stomach of dogs indigenous to Bangladesh was investigated by using latex. The hepatic, left gastric and splenic arteries sent their major branches to the stomach. The cranial and caudal branches of the left gastric artery supplied the lesser curvature of the stomach. The right gastric, and right and left gastroepiploic arteries also sent their branches to both the lesser and greater curvatures. Six or seven short gastric arteries from the splenic artery supplied the greater curvature. Anastomoses between the left and right gastric, between the left and right gastroepiploic, and between short gastric arteries and left gastric arteries were observed.

    Full Text Available Ventricular pseudoaneurysm is an uncommon, potentially fatal complication that has been associated with myocardial infarction, cardiac surgery, chest trauma, and infectious processes. Diagnosis can be challenging, as cases are rare and slowly progressing and typically lack identifiable features on clinical presentation. As a result, advanced imaging techniques have become the hallmark of identification. Ahead, we describe a patient who presents with acute decompensated heart failure and was incidentally discovered to have a large right ventricular pseudoaneurysm that developed following previous traumatic anterior rib fracture.

Sonographic monitoring is believed to be very useful both to evaluate splenomegaly and signs of portal hypertension and to reveal splenic complications (abscesses). Severe complications have been never registered. 21 refs.

    Full Text Available Splenic artery aneurysm (SAA occurs predominantly in women and the majority of them are asymptomatic until rupture. In cases of spontaneous rupture of an SAA, maternal and fetal mortality rates remain extremely high. Furthermore, the spontaneous ruptures of SAAs predominantly appear during the third trimester of pregnancy. We present the third known case of spontaneous SAA rupture during the first trimester of pregnancy, which manifested as sudden hypovolemic collapse and was successfully confronted with combined aggressive resuscitation and emergency surgical operation.

    Purpose: To evaluate the efficacy of estimating the volume of spleen embolized in partial splenic embolization (PSE) by measuring the diameters of the splenic artery and its branches. Materials and methods: A total of 43 liver cirrhosis patients (mean age, 62.19 ± 9.65 years) with thrombocytopenia were included. Among these, 24 patients underwent a follow-up CT scan which showed a correlation between angiographic estimation and measured embolized splenic volume. Estimated splenic embolization volume was calculated by a method based on diameters of the splenic artery and its branches. The diameters of each of the splenic arteries and branches were measured via 2D angiographic images. Embolization was performed with gelatin sponges. Patients underwent follow-up with serial measurement of blood counts and liver function tests. The actual volume of embolized spleen was determined by computed tomography (CT) measuring the volumes of embolized and non-embolized spleen two months after PSE. Results: PSE was performed without immediate major complications. The mean WBC count significantly increased from 3.81 ± 1.69 × 10{sup 3}/mm{sup 3} before PSE to 8.56 ± 3.14 × 10{sup 3}/mm{sup 3} at 1 week after PSE (P < 0.001). Mean platelet count significantly increased from 62.00 ± 22.62 × 10{sup 3}/mm{sup 3} before PSE to 95.40 ± 46.29 × 10{sup 3}/mm{sup 3} 1 week after PSE (P < 0.001). The measured embolization ratio was positively correlated with estimated embolization ratio (Spearman's rho [ρ] = 0.687, P < 0.001). The mean difference between the actual embolization ratio and the estimated embolization ratio was 16.16 ± 8.96%. Conclusions: The method provides a simple method to quantitatively estimate embolized splenic volume with a correlation of measured embolization ratio to estimated embolization ratio of Spearman's ρ = 0.687.

    Ultrasound-guided thrombin injection has become the initial treatment of choice for femoral access-related pseudoaneurysms. Patients typically undergo serial duplex examinations to assess for spontaneous resolution of small iatrogenic pseudoaneurysms (IPSAs) (IPSAs (>2.5 cm). We evaluated the impact of a revised treatment algorithm that includes primary treatment of both small (2.5 cm), rather than observation of smaller ones, and attempts to establish a single duplex examination via a point-of-care treatment strategy. We reviewed 105 consecutive patients treated with ultrasound-guided thrombin injection from July 2001 through September 2004. Patient, IPSAs, characteristics, and treatment methods were examined. The number of duplex examinations per patient was evaluated over the treatment interval. Also, published cost data were used to compare primary treatment of small ISPAs vs observation with serial duplex examinations. Successful thrombosis occurred in 103 (98.1%) of 105 treated pseudoaneurysms. No minor or major complications occurred after thrombin injection in either small or large ISPAs, and both failures requiring operation were in the large aneurysm group. The recurrence rate for the series was 1.9% (2/105), and both recurrences were successfully treated with an additional thrombin injection. A single injection was successful in treating 43 (97.7%) of 44 small (IPSAs, and one required a second injection. Patients had an average of 3.3 duplex examinations in our first year of treatment experience, which declined to 1.5 by our third year with the institution of a point-of-care service model for all pseudoaneurysms. Based on this decreased use of duplex examination and an average treatment cohort of 35 IPSA patients per year our institution, we determined this results in a reduction of 35 hours of laboratory time and nearly 70 ultrasounds per year. Similarly for small pseudoaneurysms, a point-of-service primary treatment program rather than observation

    The goal of this study was to investigate the difference between the learning curves of different maneuvers in laparoscopic spleen-preserving splenic hilar lymphadenectomy for advanced upper gastric cancer. From January 2010 to April 2014, 53 consecutive patients who underwent laparoscopic spleen-preserving splenic hilar lymphadenectomy via the traditional-step maneuver (group A) and 53 consecutive patients via Huang's three-step maneuver (group B) were retrospectively analyzed. No significant difference in patient characteristics were found between the two groups. The learning curves of groups A and B were divided into phase 1 (1-43 cases and 1-30 cases, respectively) and phase 2 (44-53 cases and 31-53 cases, respectively). Compared with group A, the dissection time, bleeding loss and vascular injury were significantly decreased in group B. No significant differences in short-term outcomes were found between the two maneuvers. The multivariate analysis indicated that the body mass index, short gastric vessels, splenic artery type and maneuver were significantly associated with the dissection time in group B. No significant difference in the survival curve was found between the maneuvers. The learning curve of Huang's three-step maneuver was shorter than that of the traditional-step maneuver, and the former represents an ideal maneuver for laparoscopic spleen-preserving splenic hilar lymphadenectomy.To shorten the learning curve at the beginning of laparoscopic spleen-preserving splenic hilar lymphadenectomy, beginners should beneficially use Huang's three-step maneuver and select patients with advanced upper gastric cancer with a body mass index of less than 25 kg/m 2 and the concentrated type of splenic artery.

    Purpose. The purpose of the study was to evaluate the angiographic findings and results of embolotherapy in the management of lumbar artery trauma. Methods. All patients with lumbar artery injury who underwent angiography and percutaneous embolization in a state trauma center within a 10-year period were retrospectively reviewed. Radiological information and procedural reports were reviewed to assess immediate angiographic findings and embolization results. Long-term clinical outcome was obtained by communication with the trauma physicians as well as with chart review. Results. In a 10-year period, 255 trauma patients underwent abdominal aortography. Eleven of these patients (three women and eight men) suffered a lumbar artery injury. Angiography demonstrated active extravasation (in nine) and/or pseudoaneurysm (in four). Successful selective embolization of abnormal vessel(s) was performed in all patients. Coils were used in six patients, particles in one and gelfoam in five patients. Complications included one retroperitoneal abscess, which was treated successfully. One patient returned for embolization of an adjacent lumbar artery due to late pseudoaneurysm formation. Conclusions. In hemodynamically stable patients, selective embolization is a safe and effective method for immediate control of active extravasation, as well as to prevent future hemorrhage from an injured lumbar artery

    Purpose: To evaluate the effectiveness and safety of covered stents for the management of iatrogenic arterial injury. Materials and Methods: Between 03/1998 and 12/2009, 31 patients underwent selective covered stent implantation after iatrogenic arterial injury. 12/31 of these patients (38.7 %) were hemodynamically unstable. Six different endovascular covered stent types were utilized. The primary endpoints of this study were technical and clinical success and rates of minor and major complications. Results: Initial angiograms demonstrated active extravasation in 19 (61.3 %) patients and pseudoaneurysms in 12 (38.7 %) patients. The following sites of bleeding origin were detected: axillary artery, subclavian artery, common iliac artery, external iliac artery, internal iliac artery, common femoral artery, superficial femoral artery, popliteal and fibular artery, femoro-popliteal and popliteo-crural bypasses, common hepatic artery, aberrant hepatic artery, cystic and gastroduodenal artery. In all patients bleeding was effectively controlled by covered stent implantation resulting in an immediate technical success of 100 %. Clinical success attributed to covered stent implantation was documented in 30 of the 31 patients (96.8 %). Major complications included death in four patients (11.1 %), acute thrombosis with arm ischemia in one patient (2.8 %) and stent fracture with associated pseudoaneurysm in another patient (2.8 %). In 2/31 patients (6.5 %) covered stent failure was detected and successfully treated by implantation of a second covered stent. Conclusion: Emergency and elective implantation of covered stents may be used for minimally invasive and effective management of iatrogenic arterial injury. (orig.)

    Full Text Available Abstract Pseudoaneurysm of the ascending aorta is a rare complication after cardiac surgery. Particularly, pseudoaneurysm due to postoperative infection in the ascending aorta requires surgical treatment with antibiotics. If a large sized pseudoaneurysm is located at the retrosternal space, then there is a very high risk of massive bleeding from rupture during performance of resternotomy. To avoid this risk, we performed femoro-femoral bypass under moderate hypothermia with transient circulatory arrest, and we report here on the successful result of this case.

    INTRODUCTION The spleen remains one of the most frequently injured organs following blunt abdominal trauma. In 2012, regional trauma networks were launched across England and Wales with the aim of improving outcomes following trauma. This retrospective cohort study investigated the management and outcomes of blunt splenic injuries before and after the establishment of regional trauma networks. METHODS A dataset was drawn from the Trauma Audit Research Network database of all splenic injuries admitted to English and Welsh hospitals from 1 April 2010 to 31 March 2014. Demographic data, injury severity, treatment modalities and outcomes were collected. Management and outcomes were compared before and after the launch of regional trauma networks. RESULTS There were 1457 blunt splenic injuries: 575 between 2010 and 2012 and 882 in 2012-14. Following the introduction of the regional trauma networks, use of splenic artery embolotherapy increased from 3.5% to 7.6% (P = 0.001) and splenectomy rates decreased from 20% to 14.85% (P = 0.012). Significantly more patients with polytrauma and blunt splenic injury were treated with splenic embolotherapy following 2012 (61.2% vs. 30%, P splenic artery embolotherapy since the introduction of the regional trauma networks. This may have resulted from improved access to specialist services and reduced practice variation since the establishment of these networks.

    We report an 18-year-old boy with occipital horn syndrome who developed aneurysms of the splenic and hepatic arteries. Occipital horn syndrome, also called X-linked cutis laxa or Ehlers-Danlos syndrome (EDS) type IX, is characterised by a skeletal dysplasia which includes occipital horns, broad clavicles, deformed radii, ulnae and humeri, narrow rib cage, undercalcified long bones and coxa valga. Distinctive features common to all patients are unusual facial appearance, hypermobility of finger joints, limitation of extension of elbows, chronic diarrhoea and genitourinary abnormalities. In this case report we describe the difficulties encountered in the diagnostic management of patients with EDS-related vascular lesions. (orig.)

    Splenic artery aneurysm (SAA) is a rare and usually asymptomatic vascular anomaly which carries the risk of rupture and fatal hemorrhage. It is more common in women and is usually associated with pregnancy. We present the case of rupture of SAA, 5 days after giving birth by cesarean section, which was diagnosed with Multi-Slice Computed Tomografy (MSCT) angiography and was successfully operated in the second emergency laparotomy, with the final good outcome for the mother. This case indicates that in case of sudden bleeding in the abdomen, with the development of hypovolemic shock, especially in the peripartum period, should be suspected rupture of SAA. The paper presents a critical review of this case, with a review of the literature.

    To evaluate the feasibility and effectiveness of endovascular repair for blunt popliteal arterial injuries. A retrospective analysis of seven patients with clinical suspicion of popliteal arterial injuries that were confirmed by arteriography was performed from September 2009 to July 2014. Clinical data included demographics, mechanism of injury, type of injury, location of injury, concomitant injuries, time of endovascular procedures, time interval from trauma to blood flow restoration, instrument utilized, and follow-up. All patients were male (mean age of 35.9 ± 10.3 years). The type of lesion involved intimal injury (n = 1), partial transection (n = 2), complete transection (n = 2), arteriovenous fistula (n = 1), and pseudoaneurysm (n = 1). All patients underwent endovascular repair of blunt popliteal arterial injuries. Technical success rate was 100%. Intimal injury was treated with a bare-metal stent. Pseudoaneurysm and popliteal artery transections were treated with bare-metal stents. Arteriovenous fistula was treated with bare-metal stent and coils. No perioperative death and procedure-related complication occurred. The average follow-up was 20.9 ± 2.3 months (range 18–24 months). One patient underwent intra-arterial thrombolysis due to stent thrombosis at 18 months after the procedure. All limbs were salvaged. Stent migration, deformation, or fracture was not found during the follow-up. Endovascular repair seems to be a viable approach for patients with blunt popliteal arterial injuries, especially on an emergency basis. Endovascular repair may be effective in the short-term. Further studies are required to evaluate the long-term efficacy of endovascular repair.

    The risk of overwhelming sepsis in splenectomized patients is well known and autotransplantation of splenic tissue might be considered as a prophylactic approach. Little is known, however, of the success of grafting in man. In six patients with autologous grafts after emergency splenectomy the ''trapping function'' (TF) was measured by sequential scintigraphy with heat damaged red cells every third month. To correlate TF with blood flow and histology, different experiments were done in pigs: ligation of the splenic artery or partial splenectomy or total splenectomy with grafting of fragments either subfascially or in the greater momentum. TF, blood flow with Rb-86 and immune response was measured at different times after surgery. Remnants left at the main vessels did not grow, while splenic tissue left at smaller vessels increased in size. There were great differences in blood flow per gram splenic tissue, but a significant correlation between TF and blood flow. All experimental grafts showed a normal function both of the white and the red pulp. In patients there was a growth of grafts in four, while in two no TF could be measured. TF is an indicator of relative blood flow to splenic grafts and therefore useful in the follow up of grafted patients

    Full Text Available We report the case of an 82-year-old woman who developed extensive proximal thigh swelling and persistent anaemia following internal fixation of an extracapsular neck of femur fracture with a dynamic hip screw (DHS. This was revealed to be a pseudoaneurysm of a branch of profunda femoris artery on angiography. Her case was further complicated by a concurrent pulmonary embolism (PE. She underwent endovascular coil embolisation of the pseudoaneurysm. An IVC filter was inserted and the patient was fully anticoagulated once it had been ensured that there was no active bleeding. In this case, we review the potential for anatomical variations in the blood supply to this region and discuss treatment options for a complicated patient. We recommend that a pseudoaneurysm should be part of a differential diagnosis for postoperative patients with anaemia refractory to blood transfusion so as not to miss this rare but potentially serious complication.

    Aortography for detecting hemorrhage is limited when determining the catheter treatment strategy because the artery responsible for hemorrhage commonly overlaps organs and non-responsible arteries. Selective catheterization of untargeted arteries would result in repeated arteriography, large volumes of contrast medium, and extended time. A volume-rendered hemorrhage-responsible arteriogram created with 64 multidetector-row CT (64MDCT) during aortography (MDCTAo) can be used both for hemorrhage mapping and catheter navigation. The MDCTAo depicted hemorrhage in 61 of 71 cases of suspected acute arterial bleeding treated at our institute in the last 3 years. Complete hemostasis by embolization was achieved in all cases. The hemorrhage-responsible arteriogram was used for navigation during catheterization, thus assisting successful embolization. Hemorrhage was not visualized in the remaining 10 patients, of whom 6 had a pseudoaneurysm in a visceral artery; 1 with urinary bladder bleeding and 1 with chest wall hemorrhage had gaze tamponade; and 1 with urinary bladder hemorrhage and 1 with uterine hemorrhage had spastic arteries. Six patients with pseudoaneurysm underwent preventive embolization and the other 4 patients were managed by watchful observation. MDCTAo has the advantage of depicting the arteries responsible for hemoptysis, whether from the bronchial arteries or other systemic arteries, in a single scan. MDCTAo is particularly useful for identifying the source of acute arterial bleeding in the pancreatic arcade area, which is supplied by both the celiac and superior mesenteric arteries. In a case of pelvic hemorrhage, MDCTAo identified the responsible artery from among numerous overlapping visceral arteries that branched from the internal iliac arteries. In conclusion, a hemorrhage-responsible arteriogram created by 64MDCT immediately before catheterization is useful for deciding the catheter treatment strategy for acute arterial bleeding.

    Fifty-five consecutive cases of surgically proved splenic injuries were evaluated by CT. CT correctly identified 54 splenic injuries, with one false-negative and three false-positive studies. In the single false-negative study and in two of the three false-positive studies, CT correctly indicated the presence of a large hemoperitoneum and other abdominal visceral lacerations and so correctly indicated the need for surgery. Of the 55 proved cases of splenic injury, CT revealed hemoperitoneum in 54 (99%), perisplenic clot in 47 (85%), splenic laceration in 39 (71%), and subcapsular hematoma in 13 (24%). Perisplenic clot can be distinguished from lysed blood in the peritoneal cavity and is a sensitive and specific sign of splenic trauma, even in the absence of visible splenic laceration. The authors conclude that CT is highly reliable means of evaluating splenic trauma

    Full Text Available Pleural involvement is an uncommon but well recognized complication of chronic pancreatitis, mainly in the form of pleural effusion affecting the left hemithorax. Pancreatic pseudocyst extending to the posterior mediastinum with or without communication with the pleural space is another rare form of this involvement.The treatment of chronic pancreatic pleural effusions and pancreatic pseudocysts generally starts with a conservative approach including bowel rest, drainage of the pleural effusion by repeated thoracentesis or a chest tube, and total parenteral nutrition (TPN for a period of time determined by the clinical course. Other treatment modalities including percutaneous drainage, endoscopic retrograde cholangiopancreatogram (ERCP with stenting of the pancreatic duct and surgical drainage are used if conservative approaches fail.We report a patient with a complicated pancreatic pseudocyst who showed an involvement of the posterior mediastinum and right pleural space, with conspectus sparing of the left hemithorax. The patient had a prolonged and complicated course that included recurrence of the pseudocyst with oral feedings and the development of a splenic artery aneurysm. Some of the above findings have been reported separately as uncommon complications of chronic pancreatitis and pancreatic pseudcyst, but to our knowledge a single case with all these complications was not published in the English literature.

    The aim of this study was to describe the demographics, mechanisms of injury, management and outcomes in patients who suffered splenic trauma in Christchurch, New Zealand. A retrospective study included all splenic injury patients admitted to Christchurch Public Hospital between January 2005 and August 2015. A total of 238 patients were included, with a median age of 26 years (4-88.7). Of these, 235 patients had blunt injuries. Eighty-nine had high-grade injuries. Yearly admissions of splenic trauma patients have gradually increased. A total of 173 (72.7%) patients were managed with observation; 28 patients (11.8%) had radiological intervention and 37 patients (15.5%) had splenectomy. Patients who died were significantly more likely to be older (median, 46.5 vs 25.2 years, p=0.04) and to have been admitted to ICU (100% vs 32%, p=Splenic injuries have shown a steady increase in the last decade. Splenectomy rates have decreased in favour of non-operative techniques. Radiological intervention with splenic artery embolisation was successful in all selected patients with high-grade injuries.

    2015-01-01

    Full Text Available Here, we describe the case of a 58-year-old woman diagnosed with massive splenomegaly with a malignant lymphoma that had a maximum diameter of 24 cm. Splenectomy was indicated because of thrombocytopenia and abdominal distention. Therefore, a balloon catheter was inserted preoperatively through the splenic artery for embolization and continuous infusion to reduce the spleen volume. It enabled easy handling of the spleen and minimized bleeding. The volume of the spleen was estimated at 1896 g through the skin incision, as measured by volumetric computed tomography; thus, laparoscopy seemed difficult. However, the surgery was successfully performed only with laparoscopic surgery, and the volume of the resected spleen was 1020 g. This preoperative preparation is an effective alternative to laparoscopic removal of a huge splenomegaly.

    Full Text Available Free wall rupture of the left ventricle (LV is a rare but life-threatening complication of acute myocardial infaction. Very rarely such rupture may be contained by the adhering pericardium creating a pseudoaneurysm. This condition warrants for an emergency surgery. Left ventricular aneurysm is the discrete thinning of the ventricular wall (<5 mm with akinetic or dyskinetic wall motion causing an out-pouching of the ventricle. Given the propensity for pseudoaneurysms to rupture leading to cardiac tamponade, shock, and death, compared with a more benign natural history for true aneurysms, accurate diagnosis of these conditions is important. True aneurysm, usually, calls for an elective surgery. Clinically differentiating the two conditions remains a challenge. We report the case of a patient with LV pseudoaneurysm, initially diagnosed as true aneurysm at our institution. We have attempted to review the existing literature and discussed the characteristic findings of each entity.

    The present study compares the efficacy of 915- and 2450-MHz contrast-enhanced ultrasound (CEUS)-guided percutaneous microwave coagulation with that of CEUS-guided thrombin injection for the treatment of trauma-induced spleen hemorrhage. In a canine splenic artery hemorrhage model with two levels of arterial diameter (A, microwaves and drug injection. Therapy efficacy was measured by comparing bleeding rate, hemostatic time, bleeding index, bleeding volume, and pathology. The most efficient technique was CEUS-guided 915-MHz percutaneous microwave coagulation therapy in terms of action time and total blood loss. The success rate of the 915-MHz microwave group was higher than that of the 2450-MHz microwave and the drug injection groups (except A level, P microwave group than those in the 2450-MHz microwave and drug injection groups (P microwave group, but pathologic changes of light injury could be seen in the other groups. The present study provides evidence that microwave coagulation therapy is more efficient than thrombin injection for the treatment of splenic hemorrhage. Furthermore, treatment with 915-MHz microwaves stops bleeding more rapidly and generates a wider cauterization zone than does treatment with 2450-MHz microwaves. Copyright © 2014 Elsevier Inc.

    The outcomes of 383 cases of heavy combined traumas (n=273) and isolated (n=110) closed injuries of the abdomen with spleen damage were analyzed. The overall mortality was 11.74% (n=45), whereas the mortality rate during the first day after admission was 7.83% (n=30). Removal of a spleen was executed at 228 patients. The spleen-preserving operation with ligation of splenic artery, was performed in 155 patients. The optimal level of the splenic artery ligation proved to be in its proximal and median parts. The postoperative CT-angiogarphy and Doppler US scanning together with the three-dimensional reconstruction confirmed that blood supply of the body and tail of the pancreas was satisfactory thanks to the natural collateral blood circulation. The dramatic decrease in lethality and of postoperative complication rates allows to consider spleen-preserving resections to be a good alternative to spleenectomy.

    Full text: The spleen is often involved in hematological malignancies; it is also the site of RBC destruction in thalassemia and ITP. In latter cases, splenectomy is often performed and postoperatively, detection of functioning splenic remnants affect the prognosis adversely. In this study, we assessed the usefulness of radionuclide techniques in : a) assessment of splenic function in primarily non-splenic diseases (benign or malignant), and b) detection of splenic remnant after splenectomy. 12 patients of splenomegaly and 5 patients after splenectomy underwent splenic imaging; imaging was performed using both 99m Tc-sulphur colloid (with first pass) and 99m Tc labelled heat denatured RBCs as tracers. Thus splenic perfusion, morphology and RBC trapping functions were all assessed. The colloid images usually matched the RBC images except in 2 cases where photogenic areas (presumably infarcts) were visualized on RBC scans that were missed on colloid scans. Three of the post splenectomy cases revealed functioning splenic remnants, which was also better visualized on RBC scans. It is concluded that radionuclide imaging could be used regularly for assessing function of spleen, or detecting splenic remnants

    Full Text Available A 40-year-old male with osteogenesis imperfecta (OI was admitted to the hospital with an acute right monoparesis. Diffusion-weighted MRI showed infarction in the territory of the left anterior cerebral artery (ACA and in the left posterior cerebral artery (PCA. In his vascular imaging, occlusion of the left vertebral artery (VA starting from V2 segment was consistent with dissection and pseudoaneurysm in the right ACA. We presented this case because of the presence of spontaneous and simultaneous occurrence of both intracranial and extracranial arterial dissections in OI.

    PurposeRegional portal hypertension (RPH) is an uncommon clinical syndrome resulting from splenic vein stenosis/occlusion, which may cause gastrointestinal (GI) bleeding from the esophagogastric varices. The present study evaluated the safety and efficacy of transjugular endovascular recanalization of splenic vein in patients with GI bleeding secondary to RPH.MethodsFrom December 2008 to May 2011, 11 patients who were diagnosed with RPH complicated by GI bleeding and had undergone transjugular endovascular recanalization of splenic vein were reviewed retrospectively. Contrast-enhanced computed tomography revealed splenic vein stenosis in six cases and splenic vein occlusion in five. Etiology of RPH was chronic pancreatitis (n = 7), acute pancreatitis with pancreatic pseudocyst (n = 2), pancreatic injury (n = 1), and isolated pancreatic tuberculosis (n = 1).ResultsTechnical success was achieved in 8 of 11 patients via the transjugular approach, including six patients with splenic vein stenosis and two patients with splenic vein occlusion. Two patients underwent splenic vein venoplasty only, whereas four patients underwent bare stents deployment and two covered stents. Splenic vein pressure gradient (SPG) was reduced from 21.5 ± 7.3 to 2.9 ± 1.4 mmHg after the procedure (P < 0.01). For the remaining three patients who had technical failures, splenic artery embolization and subsequent splenectomy was performed. During a median follow-up time of 17.5 (range, 3–34) months, no recurrence of GI bleeding was observed.ConclusionsTransjugular endovascular recanalization of splenic vein is a safe and effective therapeutic option in patients with RPH complicated by GI bleeding and is not associated with an increased risk of procedure-related complications

    Full Text Available Splenic abscess is a rare clinical entity with poor prognosis. But owing to imaging technique, diagnosis and prognosis have improved nowadays. Most patients who are presented with splenic abscess are immunocompromised due to predisposing risk factors like diabetes mellitus, intravenous drug abuse, trauma, bacterial endocarditis, human immunodeficiency virus (HIV, chemotherapy, or steroids. Here, we are presenting a rarer case of multiple splenic abscesses with its complication in an immunocompetent healthy adult male without any risk factor.

  17. Percutaneous treatment of femoral pseudoaneurysms: comparison of fibrin sealant against thrombin

    Directory of Open Access Journals (Sweden)

    Daniel Mendes Pinto

    2013-12-01

    Full Text Available INTRODUCTION: Femoral pseudoaneurysms are a complication that occurs in connection with up to 8% of percutaneous procedures. Of the available treatments, ultrasound guided thrombin injection has a high success rate and is well-tolerated by patients. The combination of thrombin and fibrinogen known as fibrin sealant forms a stable clot and can be used to treat pseudoaneurysms, particularly those with complex anatomy and larger size. OBJECTIVE: To compare the results of treating femoral pseudoaneurysm in two ways: Group T was treated with thrombin alone and Group T+F was treated with fibrin sealant (thrombin+fibrinogen. METHODS: A retrospective analysis was conducted of femoral pseudoaneurysm cases treated between January 2005 and December 2012. RESULTS: Twenty-eight patients were treated, 21 with thrombin alone and seven with fibrin sealant. All patients in group T were treated successfully, but only four patients in group T+F were treated successfully (57.1% success rate in Group T+F, p<0.01. The three cases of failure in group T+F needed surgery and in one of these cases the complication was embolization to the femoral bifurcation. The pseudoaneurysms that were treated with fibrin sealant were larger (25 cm3 in Group T and 57.7 cm3 in Group T+F, p=0.02 and required larger volumes of thrombin (0.5 mL in Group T and 1.0 mL in Group T+F, p<0.01. There was one complication in Group T and two complications in Group T+F (p<0.01. CONCLUSIONS: Irrespective of the small number of cases reviewed, treatment with thrombin alone was superior to treating with fibrin sealant, since it caused few complications and was more effective at correcting pseudoaneurysms.

    Non-operative management (NOM) is the standard of care in hemodynamically stable patients with blunt splenic injury after trauma. Splenic artery embolization (SAE) is reported to increase observation success rate. Studies demonstrating improved splenic salvage rates with SAE primarily compared SAE with historical controls. The aim of this study was to investigate whether SAE improves success rate compared to observation alone in contemporaneous patients with blunt splenic injury. We included adult patients with blunt splenic injury admitted to five Level 1 Trauma Centers between January 2009 and December 2012 and selected for NOM. Successful treatment was defined as splenic salvage and no splenic re-intervention. We calculated propensity scores, expressing the probability of undergoing SAE, using multivariable logistic regression and created five strata based on the quintiles of the propensity score distribution. A weighted relative risk (RR) was calculated across strata to express the chances of success with SAE. Two hundred and six patients were included in the study. Treatment was successful in 180 patients: 134/146 (92 %) patients treated with observation and 48/57 (84 %) patients treated with SAE. The weighted RR for success with SAE was 1.17 (0.94-1.45); for complications, the weighted RR was 0.71 (0.41-1.22). The mean number of transfused blood products was 4.4 (SD 9.9) in the observation group versus 9.1 (SD 17.2) in the SAE group. After correction for confounders with propensity score stratification technique, there was no significant difference between embolization and observation alone with regard to successful treatment in patients with blunt splenic injury after trauma.

    Full Text Available Mycotic pseudoaneurysm of aorta following cardiac surgery is rare but is highly fatal if it is unrecognized and untreated. Here, we report a case of a 45-year-old male patient who presented with rapidly progressive multiple pseudoaneurysms of the ascending aorta infected with multidrug resistant (MDR Pseudomonas aeruginosa at 5 weeks after cardiac transplantation, on a background of prior bridging therapy with left ventricular assistant device (LVAD. The patient was successfully treated with the newer cephalosporin, Ceftolozane/Tazobactam, in combination with surgery. This is the first reported case of mycotic pseudoaneurysm infected with MDR Pseudomonas. This case also highlights the importance of high vigilance and timely multimodality treatment in the diagnosis and management of mycotic pseudoaneurysm following cardiac transplant, especially in patients who had LVAD.

    We report three cases of splenic infarction in healthy men for the first time that amounted to high altitudes, observed in the hospital "Victor Ramos Guardia" Huaraz (3100 m). Case 1 (1995) of 55 years, born in Cuba, from Lima, caucasian suddenly presented acute abdominal pain in epigastrium, distension, nausea and vomiting, was laparotomized for acute abdomen and surgical pathology revealed thrombosis with splenic infarction splenic artery and vein. During follow-up in Lima, hemoglobin electrophoresis showed that it was heterozygous carrier of the sickle trait (Hb A: 57% Hb S: 38.5%). Case 2 (1998) of 23 years, born in Cuba, from Lima, Black said acute abdominal pain in left hypochondrium, shortness of breath and chest pain, clinical examination and radiography of the abdomen showed the spleen volume increased. Case 3 (2006) of 17 years, natural and from Lima, mestizo, who came on tour promotion, acute abdominal pain referred onset in the epigastrium and left hypochondrium, headache, increase heat, nausea and vomiting, pharyngitis was found acute and painful, and spleen increased in size by clinical and x-ray of abdomen simple stand. None had no history of hemoglobinopathy and anemia. In general, medical management was supportive and cases 2 and 3 are recommended hemoglobin electrophoresis. We conclude that we must think of splenic infarction associated with height in any healthy person who is first at high altitude (> 3000m) and having a sudden acute abdominal pain in epigastrium and / or left hypochondrium, pain and palpable spleen and radiological study compatible with image. In this case is indicated by hemoglobin electrophoresis to determine whether there is an individual heterozygous carrier of the sickle trait. splenic infarction, high altitude, sickle trait, Huaraz.

    BACKGROUND: Arterial thrombosis is a very rare, but recognised complication of inflammatory bowel disease that can result in significant morbidity and mortality. CASE PRESENTATION: We present the case of a 48-year-old female with previously well-controlled ulcerative colitis who presented with severe left upper quadrant abdominal pain. Imaging investigations subsequently revealed a large intra-aortic mural thrombus extending into the coeliac axis complicated by splenic infarction. This occurred in the absence of other prothrombotic states such as thrombophilias or vasculitis. CONCLUSION: This case highlights the frequently overlooked association between inflammatory bowel disease and arterial thrombosis.

    Pseudoaneurysm is an uncommon sequela of infective endocarditis. We treated a 44-year-old man who had an active case of group B streptococcal infective endocarditis of the aortic valve despite no evidence of valvular dysfunction or vegetation on his initial transesophageal echocardiogram. After completing 6 weeks of intravenous antibiotic therapy, the patient developed a sinus of Valsalva pseudoaneurysm and severe aortic regurgitation caused by partial detachment of the left coronary cusp. We used a pericardial patch to close the pseudoaneurysm and repair the coronary cusp. This case shows the importance of routine clinical follow-up evaluation in infective endocarditis, even after completion of antibiotic therapy. Late sequelae associated with infective endocarditis or its therapy include recurrent infection, heart failure caused by valvular dysfunction (albeit delayed), and antibiotic toxicity such as aminoglycoside-induced nephropathy and vestibular toxicity.

    Full Text Available We report the case of a 66-year-old woman admitted to the intensive care unit (ICU for ongoing dyspnea and hemoptoe. She was operated upon in 1979 for aortic coarctation by the interposition of a 14 mm Dacron prosthesis from the left subclavian artery to descending aorta. Clinical evaluation performed over the years was normal with no signs of cardiac failure or prosthesis malfunctioning. The computed tomography scans (CT showed a progressive increase of the descending aorta diameters and the onset of a pseudo-aneurysm of 50 mm in diameter. Patient was re-operated through a median sternotomy enlarged by a left thoracotomy and intra-operative findings revealed the pseudo-aneurysm originating from a dehiscence of the proximal suture. In order to allow a safe reconstruction of the dilated subclavian artery, a T-shaped composed graft was confectioned and then sutured to the descending aorta and the subclavian artery, respectively. Post-operative course was uneventful and three months CT scan showed a normal position of the composed graft.

    Pseudoaneurysms are rare complications of myocardial infarction with propensity for rupture. There is still a challenge with which diagnostic imaging we performed a final diagnosis of pseudoaneurysm and differentiate it from true aneurysm what is clinically important due to the different treatment. We presented the unusual case of a 56-year-old man with signs of decompensated heart failure which had worsened a few months before hospitalization. We believed that during worsening of symptoms the patient suffered a silent myocardial infarction complicated by subacute free wall rupture which resulted into left ventricular pseudoaneurysm formation without tamponade. Echocardiography showed dilatative cardiomyopathy which was already present years before and a very rare location of the left ventricular pseudoaneurysm on the anterolateral part of the left ventricle. Pseudoaneurysm was confirmed with CT scan. Due to the severity of contractile dysfunction and no response in treatment for congestive heart failure the directive for the resection was tempered and the patient died due to the progressive heart failure and embolic phenomena. This report shows the importance of non-invasive imaging diagnostic evaluation of acute decompensated heart failure where echocardiography and chest X-ray are the first diagnostic steps. Based on those findings further imaging diagnostic steps must be performed such as CT scan in our case which finally confirms left ventricular pseudoaneurysm with dilatative cardiomyopathy

    The aim of this study was to establish the accuracy of dynamic contrast-enhanced magnetic resonance imaging (DCEMRI) in assessing the site of origin and the patency of the hepatic arteries. Sixty-one patients were examined with serial DCEMRI. MRI was performed at 1.0 T with a rapid multi-section breath-hold fast low-angle shot (FLASH) technique in the coronal oblique plane before and at 10, 40 and 70 s after a bolus of gadolinium-DTPA. The hepatic, left gastric, gastroduodenal, splenic and superior mesenteric arteries were examined. The main portal vein, its right and left intrahepatic divisions, and the splenic and superior mesenteric veins were also assessed. The common hepatic artery was occluded in one patient. The right hepatic artery was seen in 59 patients, left hepatic in 54, left gastric in 43, gastroduodenal in 54, splenic in 60 and superior mesenteric artery in 61. Results were concordant with surgery in 38 of 39 cases and with X-ray angiography in 21 of 22 cases. In the detection of aberrant vessels DCEMRI had a sensitivity of 89 %, a specificity of 100 % and an accuracy of 97 %. All five veins were occluded in 1 patient. The main portal vein was patent in 56 patients, occluded in 2 and narrowed in 2. Thirty-two patients had upper abdominal varices. It is concluded that DCEMRI with sequential imaging provides a non-invasive demonstration of hepatic arterial and venous structures. (orig.). With 6 figs., 1 tab

  7. Splenic abscess: a rare presentation

    2015-01-01

    Full Text Available Splenic abscess is a rare clinical entity with an incidence of 0.2-0.7% in autopsy-based studies. When untreated, splenic abscess is associated with nearly 100% mortality; in treated patients, the mortality rate is 16.6% during the first 90 days. It mostly occurs in patients with neoplasia, immunodeficiency, trauma, diabetes or splenic infarct. The incidence of splenic abscess is thought to be growing because of the increase in the number of immunocompromised patients who are particularly at risk for this disease and also because of the widespread use of diagnostic modalities. However, the optimal treatment for this remains unclear. We present a case of a 42-year-old man diagnosed with multiloculated splenic abscess and was subjected to splenectomy.

    A 53-year-old male suffered splenic infarction etiologically related to atrial fibrillation and non-obstructive hypertrophic cardiomyopathy. The main clinical manifestations were a one-month history of epigastric and left upper quadrant pain, with tenderness to palpation in the later zone. Laboratory tests revealed a slight leucocytosis (14.700) with left shift and a marked increase in LDH concentration (945 IU). Abdominal CAT and arteriography established the diagnosis, Echography proved normal. Patient evolution was satisfactory with conservative medical treatment. We conclude that splenic infarction should be considered in all cases of acute or chronic pain in the left hypochondrium. The diagnosis is established by CAT, arteriography and hepatosplenic gammagraphy. Medical management is initially advocated, surgery being reserved for those cases involving complications or in which diagnosis is not clear. Emphasis is placed on the main etiological, clinical, diagnostic and management characteristics of splenic infarction.

    latrogenic femoral pseudoaneurysm is a well-known vascular access site complication. Many invasive and noninvasive techniques have been proposed for the management of this relatively common complication. In this study, we aimed to evaluate efficiency and safety of stethoscope-guided compression as a novel noninvasive technique in the femoral pseudoaneurysm treatment. We prospectively included 29 consecutive patients with the diagnosis of femoral pseudoaneurysm who underwent coronary angiography. Patients with a clinical suspicion of femoral pseudoaneurysm were referred to colour Doppler ultrasound evaluation. The adult (large) side of the stethoscope was used to determine the location where the bruit was best heard. Then compression with the paediatric (small) side of the stethoscope was applied until the bruit could no longer be heard and compression was maintained for at least two sessions. Once the bruit disappeared, a 12-hour bed rest with external elastic compression was advised to the patients, in order to prevent disintegration of newly formed thrombosis. Mean pseudoaneurysm size was 1.7 +/- 0.4 cmx 3.0 +/- 0.9 cm and the mean duration of compression was 36.2 +/- 8.5 minutes.Twenty-six (89.6%) of these 29 patients were successfully treated with stethoscope-guided compression. In 18 patients (62%), the pseuodoaneurysms were successfully closed after 2 sessions of 15-minute compression. No severe complication was observed. Stethoscope-guided compression of femoral pseudoaneurysms is a safe and effective novel technique which requires less equipment and expertise than other contemporary methods.

    The arterial and portal components of total liver blood flow were determined quantitatively in 31 patients by means of a new, non-invasive method. Sequential hepato-splenic scintigraphy has been employed, using a scintillation camera linked to a computer system. In normals, the proportion of portal flow was 71%, whereas in patients with portal hypertension it averaged 21%. Our experience indicates that the procedure can be of considerable value in the pre-operative diagnosis and postoperative follow-up of portal hypertension.

    The purpose of this study was to evaluate the accuracy of MDCT for preoperative assessment of hepatic vascular anatomy and the identification of liver-transplantation (OLT) patients at risk of developing subsequent splenic artery steal syndrome (SASS). A total of 145 patients with liver cirrhosis who had undergone OLT and had pre-operative three-phase MDCT (4- to 64-rows) within 100 days before OLT were enrolled retrospectively. MDCT and 3Ds were reviewed by two independent blinded observers (O1/O2). Pre-operative imaging findings were correlated with intra-operative results; findings indicative for SASS were correlated with clinical data and DSA. Among all 145 patients, 16 patients (11%) showed accessory hepatic arteries (accuracy O1/O2, 97%; with 3Ds, 100%); 32 (22%) patients had replaced hepatic arteries (accuracy O1, 97%; O2, 95%; with 3Ds, 100%; κ=0.87 and 0.89, P<0.001). Among 119 patients, 12 patients developed SASS after OLT. The logistic regression model revealed the spleen volume (P=0.0105) as a predictive factor of SASS. With spleen volumes ≥829 ml, an accuracy of 75% for prediction of SASS was obtained. MDCT with three-dimensional post-processing (3Ds) was highly accurate for pre-operative hepatic vessel evaluation in patients before OLT. In addition, spleen volume was a predictive factor for developing SASS after OLT. (orig.)

    To investigate the feasibility and safety of Da Vinci surgical robot in the dissection of splenic hilar lymph nodes for gastric cancer patients with total gastrectomy. Clinical data of two cases who underwent total gastrectomy for cardia cancer at our department in January 2016 were analyzed retrospectively. Two male patients were 62 and 55 years old respectively, with preoperative diagnosis as cT2-3N0M0 and cT1-2N0M0 gastric cancer by gastroscope and biopsy, and both received robotic total gastrectomy spleen-preserving splenic hilar lymph node dissection successfully. The operative time for splenic hilar lymph node dissection was 30 min and 25 min respectively. The intraoperative estimated blood loss was both 100 ml, while the number of total harvested lymph node was 38 and 33 respectively. One dissected splenic hilar lymph node and fatty tissues in two patients were proven by pathological examinations. There were no anastomotic leakage, pancreatic fistula, splenic infarction, intraluminal bleeding, digestive tract bleeding, aneurysm of splenic artery, and other operation-associated complications. Both patients suffered from postoperative pneumonia, and were cured by conservative therapy. The robotic spleen-preserving splenic hilar lymph node dissection is feasible and safe, but its superiority needs further evaluation.

    To investigate the pathophysiology of human spleen, splenic contraction following subcutaneous injection of epinephrine was measured in 45 patients with various disorders using single photon emission computed tomography (SPECT). The splenic contraction rates and percent decreases in splenic counts (ejection rates) in 5 controls were 34.5 +- 10.0 percent (mean +- SD) and 16.4 +- 6.9 percent respectively. With regard to non-Hodgkin lymphoma, the splenic contraction and ejection rates in 8 patients with no splenic involvement diagnosed by CT and/or /sup 67/Ga scintigraphy were 27.3 +- 7.0 percent and 9.4 +- 7.0 percent respectively, while these values in 6 patients with splenic involvement diagnosed by presence of splenomegaly, CT and/or /sup 67/Ga scintigraphy were 12.8 +- 5.8 percent and 2.5 +- 1.6 percent respectively. Both the values in the patients with splenic involvement were low (p < 0.01, p < 0.1) compared with those in the patients without splenic involvement. The splenic contraction and ejection rates in 7 patients with splenomegaly due to portal hypertension were averaged 33.5 +- 6.7 percent and 13.8 +- 4.5 percent respectively. These values were comparable to those in controls. All 3 patients with leukemia and splenomegaly showed exceedingly low values of the splenic contraction and ejection rates. The values were also remarkably low in a patient with splenic metastasis of unknown origin.

    Aim: The objective of this study is to evaluate the efficacy and safety of image-guided percutaneous splenic interventions as diagnostic or therapeutic procedures. Materials and methods: We performed a retrospective review of our interventional records from July 2001 to June 2006. Ninety-five image-guided percutaneous splenic interventions were performed after informed consent in 89 patients: 64 men and 25 women who ranged in age from 5 months to 71 years (mean, 38.4 years) under ultrasound (n = 93) or CT (n = 2) guidance. The procedures performed were fine needle aspiration biopsy of focal splenic lesions (n = 78) and aspiration (n = 10) or percutaneous catheter drainage of a splenic abscess (n = 7). Results: Splenic fine needle aspiration biopsy was successful in 62 (83.78%) of 74 patients with benign lesions diagnosed in 43 (58.1%) and malignancy in 19 (25.67%) patients. The most common pathologies included tuberculosis (26 patients, 35.13%) and lymphoma (14 patients, 18.91%). Therapeutic aspiration or pigtail catheter drainage was successful in all (100%) patients. There were no major complications. Conclusions: Image-guided splenic fine needle aspiration biopsy is a safe and accurate technique that can provide a definitive diagnosis in most patients with focal lesions in the spleen. This study also suggests that image-guided percutaneous aspiration or catheter drainage of splenic abscesses is a safe and effective alternative to surgery

    Full Text Available Abstract Background Ankle pain and swelling following sports injuries are common presenting complaints to the accident and emergency department. Frequently these are diagnosed as musculoskeletal injuries, even when no definitive cause is found. Vascular injuries following trauma are uncommon and are an extremely rare cause of ankle swelling and pain. These injuries may however be limb threatening and are important to diagnose early, in order that appropriate treatment can be delivered. We highlight the steps to diagnosis of these injuries, and methods of managing these injuries. It is important for clinicians to be aware of the potential for this injury in patients with seemingly innocuous trauma from sports injuries, who have significant ankle pain and swelling. Case presentation A young, professional sportsman presented with a swollen, painful ankle after an innocuous hyper-plantar flexion injury whilst playing football, which was initially diagnosed as a ligamentous injury after no bony injury was revealed on X-Ray. He returned 2 days later with a large ulcer at the lateral malleolus and further investigation by duplex ultrasound and transfemoral arteriogram revealed a Pseudo-Aneurysm of the Anterior Tibial Artery. This was initially managed with percutaneous injection of thrombin, and later open surgery to ligate the feeding vessel. The patient recovered fully and was able to return to recreational sport. Conclusion Vascular injuries remain a rare cause of ankle pain and swelling following sports injuries, however it is important to consider these injuries when no definite musculo-skeletal cause is found. Ultrasound duplex and Transfemoral arteriogram are appropriate, sensitive modalities for investigation, and may allow novel treatment to be directed percutaneously. Early diagnosis and intervention are essential for the successful outcome in these patients.

    One common complication after major pancreatic surgery is bleeding. Herein we describe a case of pancreatic pseudoaneurysm which developed after pylorous preserving pancreaticoduodenectomy for common bile duct cancer. Three attempts of transcatheter embolization failed since feeders to the pseudoaneurysm had unfavorable anatomy. Direct percutaneous N-butyl cyanoacrylate injection was performed under fluoroscopy-guidance and the pseudoaneurysm was successfully treated. Percutaneous fluoroscopy-guided direct N-butyl cyanoacrylate injection may be a useful alternative when selective transcatheter embolization fails or is technically challenging.

    Cysts of spleen are rare entities. Congenital splenic cysts are even more uncommon comprising of only 10% of benign non-parasitic cysts. We report a case of 22 years old female who presented with history of 2 years abdominal pain and gradual distension. Ultrasound and computed tomography (CT) both were suggestive of splenic cyst. Laboratory tests show thrombocytopenia with platelets count of 97000 per cubic millimeter and anemia with hemoglobin 8.7 gram per deciliter. Serological tests were negative for parasitic infection. Splenectomy was done and the weight of the spleen was found to be 1.5 kilogram. Histopathological findings are consistent with splenic epithelial cyst. The aetiology, diagnostic modalities and treatment options are discussed in the case report. (author)

    Full Text Available Dissections of the cervical arteries cause about 20% of total juvenile strokes. Approximately 4% of the carotid artery dissections are due to a (polytrauma such as car accidents. Despite improved diagnostic facilities, traumatic dissections are often underdiagnosed or diagnosed too late due to a lack of awareness of potential initial signs and symptoms.We report here a case of a delayed embolic stroke after a car accident caused by a dissection of the carotid artery and subsequent pseudoaneurysm.To reduce the long-term morbidity or mortality of multiple trauma patients, an early detection of cervical carotid and vertebral dissections is strictly necessary.

    Abdominal aortic pseudoaneurysm is a rare but life-threatening condition that occurs due to penetrating or blunt trauma. Clinical manifestations are variable, and the time interval from the initial trauma to diagnosis is variable. A prompt diagnosis and an aggressive management approach are required to avoid catastrophic complications. Possible treatment options are open surgical repair, endovascular repair, pseudoanerysmal sac thrombosis induction through direct thrombin injection, and coil embolization. Here, we present the case of a 75-year-old man affected by an infrarenal abdominal aortic pseudoaneurysm presenting with abdominal and lumbar pain for 3 days, who was successfully treated with an endograft.

    Background: Splenic autotransplantation seems to be the only alternative for preservation of splenic tissue, after total splenectomy. The present study was carried out to analyze Escherichia coli depuration by mononuclear phagocyte system organs after total splenectomy and splenic autotransplantation. Methods: We utilized an experimental model including young and adult Wistar rats, of both sexes, submitted to total splenectomy and splenic autotransplantation. The evaluation method was intravenous inoculation of a suspension of Escherichia coli labeled with technetium-99m. We analyzed bacteria uptake by mononuclear phagocyte system organs and bacteria remnant in the bloodstream. Results: There was no difference between young and adult animals in bacteria uptake by mononuclear phagocyte system organs. In the comparison of groups, it was found out that the mean percent uptake by spleen and liver of animals in the control group was higher than that observed for animals with splenic implants. However, bacteria uptake in the lung was higher in the splenic implant group than in the control group. Although spleen bacteria uptake in the control group animals has been higher than that of animals in the splenic implant group, the remnant bacteria in the bloodstream was similar. Animals submitted to isolated total splenectomy showed higher bacteria remnant in the bloodstream than animals of the control group or the group submitted to total splenectomy combined with splenic autotransplantation. Conclusion: Our results indicate that autogenous splenic implant is efficacious in bacteria depuration in rats, by means of their macrophages phagocytosis. In addition, it does not modify bacteria removal function of liver and lung

    Fifty patients with abdominal trauma and possible splenic injury were evaluated by computed tomography (CT). CT correctly diagnosed 21 of 22 surgically proved traumatic sesions of the spleen (96%). Twenty-seven patients had no evidence of splenic injury. This was confirmed at operation in 1 patient and clinical follow-up in 26. There were one false negative and one false positive. In 5 patients (10%), CT demonstrated other clinically significant lesions, including hepatic or renal lacerations in 3 and large retroperitoneal hematomas in 2. In adolescents and adults, CT is an accurate, noninvasive method of rapidly diagnosing splenic trauma and associated injuries. Further experience is needed to assess its usefulness in evaluating splenic injuries in infants and small children.

    Right ventricular (RV) pseudoaneurysm caused by trauma is very rare. We report a case of RV pseudoaneurysm which resolved without surgical treatment in a patient who survived a falling accident. Echocardiography failed to identify the pseudoaneurysm. Electrocardiography-gated CT showed a 17-mm-sized saccular pseusoaneurysm arsing from the RV outflow tract with a narrow neck. Follow-up CT after two months showed spontaneous obliteration of the lesion.

    We attempted to evaluate the usefulness of Doppler sonography in the diagnosis of uterine vascular abnormality caused by previous D and E, and to report that transarterial embolization is an excellent treatment modality. We analyzed gray-scale US, color/duplex Doppler US and angiographic findings in seven patients with radiologically proven uterine vascular abnormality. Two of the seven cases were pseudoaneurysms and five of the seven cases were AVMs. n one of the AVMS, two small pseudoaneurysms were combined. In all cases, transarterial embolizations using 3 mm coil or/and gelfoam particles were performed. Follow-up US studies, including color Doppler US, were performed. on color/duplex Doppler sonography, two cases of pseudoaneurysm showed blood pools with turbulent arterial flow, and five cases of AVM showed asymmetrically increased cascularity, with vailable high velocities composed of the pulsatile arterial flow, with a high diastolic component. on angiography, the former showed pseudoaneruysmal sacs, and the latter densely opacified vascular tangles. No more abnormal uterine bleeding was shown following transarterial embolization in all cases. Color/duplex Doppler sonography was valuable in the diagnosis or treatment of abnormal uterine bleeding caused by uterine vascular abnormality such as acquired AVM or pseudoaneruysm.

    Splenic artery embolization (SAE) in the presence of contrast blush (CB) has been recommended to reduce the failure rate of nonoperative management. We hypothesized that the presence of CB on computed tomography has minimal impact on patient outcomes. A retrospective review was conducted of all children (splenic trauma over a 10-year period at a level 1 pediatric trauma center. Data are presented as mean ± standard error of mean. Seven hundred forty children sustained blunt abdominal trauma, of which 549 had an identified solid organ injury. Blunt splenic injury was diagnosed in 270 of the 740 patients. All patients were managed nonoperatively without SAE. CB was seen on computed tomography in 47 patients (17.4%). There were no significant differences in the need for blood transfusion (12.5% vs 11.1%) or length of stay (3.1 vs 3.3 days) or need for splenectomy when compared in children with or without CB. Pediatric trauma patients with blunt splenic injuries can be safely managed without SAE and physiologic response and hemodynamic stability should be the primary determinants of appropriate management.

    Full Text Available Fundamento y objetivo: la estrecha relación anatómica del páncreas con los vasos esplénicos y el bazo es responsable de complicaciones esplénicas en el curso de la pancreatitis aguda. El objetivo es presentar dos casos clínicos de pancreatitis aguda grave que sufrieron infarto esplénico como complicación de la enfermedad pancreática. Pacientes, participantes: en un periodo de tres meses, dos pacientes fueron diagnosticados de infarto esplénico secundario a pancreatitis aguda. En ambos casos el diagnóstico y seguimiento evolutivo del infarto esplénico se hizo a través de tomografía axial computerizada. Resultados: en el primer paciente, las imágenes muestran de forma inequívoca la afectación de la arteria esplénica por el proceso inflamatorio pancreático. En el segundo, no se pudo demostrar afectación de los vasos esplénicos, por lo que la única posible explicación etiológica es un incremento de coagulabilidad intravascular. Conclusiones: sería recomendable añadir las complicaciones esplénicas al conjunto de complicaciones graves extrapancreáticas de la pancreatitis aguda. La tomografía axial computerizada es de gran utilidad para la detección y seguimiento de las complicaciones esplénicas de la pancreatitis aguda.Background and objective: the close anatomic relationship of the pancreas with the splenic vessels and the spleen is responsible for splenic complications in the course of acute pancreatitis. Our objective was to report two cases of severe acute pancreatitis complicated by splenic infarction. Patients: in a three-month period of time two patients were diagnosed with splenic infarction secondary to acute pancreatitis. In both cases splenic infarction diagnosis and follow-up were carried out using computed tomography. Results: in the first case images clearly showed a narrowing of the splenic artery due to the inflammatory pancreatic condition. In the second case no involvement of the splenic vessels could

He had undergone a difficult colonoscopy two days prior due to a tortuous colon. Initial vital signs were normal. He looked uncomfortable and had significant left upper quadrant abdominal tenderness with guarding. Thirty minutes after ED arrival, his blood pressure dropped to 73/59 mmHg, requiring aggressive fluid resuscitation. Bedside focused assessment with sonography in trauma (FAST exam demonstrated free fluid in the abdomen with mixed echogenicity of the spleen, suggestive of splenic injury. Computed tomography (CT demonstrated a large subcapsular splenic hematoma with active extravasation and surrounding intraperitoneal free fluid (Figure, Video. He was admitted to the surgical intensive care unit. Hemorrhage continued after interventional radiology performed embolization of the splenic artery. He then required laparoscopic splenectomy on hospital day 2 to control bleeding. He subsequently did well and was discharged on hospital day 10.

    Non-operative management (NOM) is now the primary treatment for blunt splenic injuries in children. Only one study has examined the use of NOM in a Scandinavian population. Thus, the purpose of this study is to report our experience in treating children with blunt splenic injuries with NOM at a Danish university hospital. We conducted a retrospective observational study of 34 consecutive children (aged 16 years or less) admitted to our level 1-trauma centre with blunt splenic injury in the 12-year period from 1 January 2001 to 31 December 2012. Data on patients and procedures were obtained by review of all medical records and re-evaluation of all initial computed tomographies (CT). We included 34 children with a median age of 10.5 years (67.6% males) in this study. All patients were scheduled for NOM, and two (5.9%) patients underwent splenic artery embolisation (SAE). Two (5.9%) patients later needed surgical intervention. The NOM success rate was 88% (95% confidence interval (CI): 73-97%) without SAE and 94% (95% CI: 80-99%) with SAE. We found no difference in the American Association for the Surgery of Trauma grade when comparing the initial CT evaluation (mean 2.59 ± 1.1) with the CT re-evaluation (mean 2.71 ± 0.94); p = 0.226. We demonstrated a high degree of success and safety of non-operative treatment in children with blunt splenic injury in a Scandinavian setting. Our results are comparable to international findings.

    1994-01-01

    The size of the normal spleen was estimated by CT in 153 children, examined with indication unrelated to splenic disease. In each patient the width, thickness, length and volume of the spleen were calculated. Measurements were also normalized to the transverse diameter of the body of the first lumbar vertebra. The spleen underwent significant growth during the first 4 years of life and reached maximum size at the age of 13. There were no differences in splenic volume between boys and girls. Splenic thickness correlated best with normal splenic volume. The strongest correlation was also found between splenic thickness and volume in a group of 45 children with clinically evident splenomegaly. Splenic thickness, an easy-to-use measurement, may be employed in everyday practice to represent splenic volume on CT. (orig.)

    A new detachable microvascular plug (MVP, Reverse Medical ® , Irvine, CA, USA) has been recently developed; three models are available according to the size (MVP3-MVP5-MVP7). MVP3 and MVP5 are released through a 0.027″ microcatheter, MVP7 through a 4 Fr catheter. This series aims to describe an initial single-center experience examining intraprocedural safety and technical success of MVP. Ten patients (mean age 55.1 years) have been treated for arterial embolization using MVP; eight extracranial and two intracranial arterial embolizations have been performed. The embolizations were because of: four bleedings, three aneurysms, two pseudoaneurysms, and one presurgical nephrectomy. MVP3 was used in five cases, MVP5 in four cases, and MVP 7 once. In all cases, the MVP was successfully released in MVP was the sole embolizing agent employed, while in four subjects, it was positioned complementary after coils. The technical and clinical success was obtained in 100%; hemorrhages were interrupted and aneurysms and pseudoaneurysms did not show recanalization at follow-up. MVP seems to be a safe embolizing device that interventional radiologists should consider when facing arterial embolization of both body and neuroarterial districts; the main advantage is related to MVP3 and MVP5 models that can be adopted for distal embolization thanks to the precise release through 0.027″ microcatheter.

    The middle meningeal artery (MMA) is a very important artery in neurosurgery. Many diseases, including dural arteriovenous fistula (DAVF), pseudoaneurysm, true aneurysm, traumatic arteriovenous fistula (AVF), moyamoya disease (MMD), recurrent chronic subdural hematoma (CSDH), migraine and meningioma, can involve the MMA. In these diseases, the lesions occur in either the MMA itself and treatment is necessary, or the MMA is used as the pathway to treat the lesions; therefore, the MMA is very important to the development and treatment of a variety of neurosurgical diseases. However, no systematic review describing the importance of MMA has been published. In this study, we used the PUBMED database to perform a review of the literature on the MMA to increase our understanding of its role in neurosurgery. After performing this review, we found that the MMA was commonly used to access DAVFs and meningiomas. Pseudoaneurysms and true aneurysms in the MMA can be effectively treated via endovascular or surgical removal. In MMD, the MMA plays a very important role in the development of collateral circulation and indirect revascularization. For recurrent CDSHs, after burr hole irrigation and drainage have failed, MMA embolization may be attempted. The MMA can also contribute to the occurrence and treatment of migraines. Because the ophthalmic artery can ectopically originate from the MMA, caution must be taken to avoid causing damage to the MMA during operations.

    Introduction: The purpose of the present study was to analyze complications following antegrade puncture of the common femoral artery (CFA) and the superficial femoral artery (SFA) using vascular closure systems (VCS). Methods: A single-center, retrospective study was performed after obtaining approval from the institutional review board and informed consent from all patients. At our center, the CFA or SFA are used for arterial access. All patients were evaluated clinically on the same day. If there was any suspicion of an access site problem, Duplex ultrasound was performed. Results: Access location was the CFA in 50 patients and the SFA in 130 patients. The sheath size ranged from 4F to 10F. Two patients had to be excluded because of lack of follow-up. Successful hemostasis was achieved in 162 of 178 cases (91 %). The following complications were observed in 16 patients (8.9 %): 4 pseudoaneurysms (2.2 %), 11 hematomas (6.2 %), and 1 vascular occlusion (0.5 %). The two pseudoaneurysms healed spontaneously, in one case an ultrasound-guided thrombin injection was performed, and one aneurysm was compressed manually. No further medical therapy was needed for the hematomas. The one vascular occlusion was treated immediately with angioplasty using a contralateral approach. No significant difference was noted between the CFA and the SFA group with respect to complications (p = 1.000). Conclusions: The use of closure devices for an antegrade approach up to 10F is feasible and safe. No differences in low complication rates were observed between CFA and SFA.

    Full Text Available BACKGROUND An injured spleen is a well-known entity to those involved in trauma care. The majority of individual with a splenic injury now receive nonoperative intervention and therapy. This shift from operative to nonoperative treatment over the past several decades is a tremendous success story in which clinical judgment and reason triumphed over standard surgical dogma. In emergency room, restoration of airway, breathing and circulation should be focussed on. A careful history is the most important one. Nevertheless, the severity of the splenic injury plays a dominant part in determining whether nonoperative management is appropriate or-if-not-whether splenorrhaphy or splenectomy will be the more appropriate surgical option. As a general rule, younger, healthier patients with lower grade splenic injuries and fewer associated injuries and comorbidities are usually managed nonoperatively or with splenic repair, whether unstable, actively bleeding patients with more severe splenic trauma and/or multiple associated injuries require splenectomy. The aim of the study is to evaluate- 1. The impact of blunt or penetrating abdominal trauma on spleen. 2. Various modes of injury. 3. Various modes of clinical presentation of cases. 4. The value of various available investigations employed. 5. The various methods of treatment. 6. The morbidity and mortality. MATERIALS AND METHODS This study was a prospective study of 20 cases of splenic injury admitted in the triage ward of Mahatma Gandhi Memorial Government Medical College Hospital, Trichy, over a period of 2 years from December 2014 to December 2016. Once the patient is admitted, the name, age, sex and mode of injury are noted. The time interval between splenic injury and admission and time interval between admission to hospital and surgery are recorded. After resuscitating the patient, all patients were subjected to careful clinical examination. RESULTS The total number of patients who had sustained

    The management of blunt splenic injuries (BSI) has evolved toward strategies that avoid splenectomy. There is growing adoption of interventional radiology (IR) techniques in non-operative management of BSI, with evidence suggesting a corresponding reduction in emergency laparotomy requirements and increased splenic preservation rates. Currently there are no UK national guidelines for the management of blunt splenic injury. This may lead to variations in management, despite the reorganisation of trauma services in England in 2012. A survey was distributed through the British Society of Interventional Radiologists to all UK members aiming to identify availability of IR services in England, radiologists' practice, and attitudes toward management of BSI. 116 responses from respondents working in 23 of the 26 Regional Trauma Networks in England were received. 79% provide a single dedicated IR service but over 50% cover more than one hospital within the network. All offer arterial embolisation for BSI. Only 25% follow guidelines. In haemodynamically stable patients, an increasing trend for embolisation was seen as grade of splenic injury increased from 1 to 4 (12.5%-82.14%, pSplenic embolisation is offered for a variety of injury grades, providing the patient remains stable. Variation in interventional radiology services remain despite the introduction of regional trauma networks. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Objective: To investigate the flexibility of both the covered stents specially designed for use in intracranial vasculature and the delivering system in passing through the bone tube and the physiological curves of the cranial internal carotid artery (CICA) to reach the targeted area, the performance (adherence) of the covered stents in occluding vascular wall diseases and the impact on the vascular branches of the covered segment. Methods: The covered stents specially designed for use in intracranial vasculature were used to treat 13 patients with CICA diseases using endovascular techniques. There were 4 huge pseudoaneurysms, 4 giant aneurysms, 3 small wide-necked aneurysms, 1 giant pseudoaneurysm with concurrent internal carotid cavernous fistula (CCF), and 1 CCF. Prior to the detachment of the covered stents, balloon occlusion test (BOT) of the internal carotid artery on the diseased side and whole-brain digital subtraction angiography (DSA) were performed in all the patients. Three to 16 months following procedure, DSA and clinical follow-ups were performed. Results: Thirteen patients all tolerated the BOT well with the DSA demonstrating well-opened anterior and posterior communicating arteries. The covered stents and the delivering systems all successfully passed CICA to reach the targeted diseased area, with the diseased segments of the internal carotid artery including C3-C4 in 4 cases, C4-C5 in 4 and C6-C7 in 5. Immediately following the detachment of the covered stents, DSA demonstrated that 7 aneurysms were completely occluded, 4 aneurysms had slight endoleak, and 1 CCF had markedly-decreased blood flow through the fistula. In the patient with concurrent pseudoaneurysm and CCF, the pseudoaneurysm disappeared and the blood flow through the fistula was markedly-reduced immediately following the stenting procedure. Apart from one patient with aneurysmal subarachnoid hemorrhage who died due to extensive vascular spasm on the 9th day following the stenting

    To study the prevalence and management of splenic trauma in relation to its mode and grade. All cases admitted in emergency with abdominal trauma and splenic injury. The data of all the patients who had splenic trauma was entered on a proforma and analyzed. A total of 44 patients with ages between 20-40 years presented with splenic injury; 32(72.7%) were male. The commonest mode of splenic trauma was blunt abdominal injury (50%), and most (47%) patients had Grade- III injury. Splenectomy was carried out in 84% patients, while 9% underwent splenic salvage. Seven (15.9%) patients with splenectomy died in the series. Splenic injury was mostly caused by blunt abdominal trauma. Proper assessment of the grade of injury at the time of laparotomy resulted in more splenic salvage procedures with decreased risk of complications. (author)

    Purpose: Colonoscopy is reported to be a safe procedure that is routinely performed for the diagnosis and treatment of colorectal diseases. Splenic rupture is considered to be a rare complication with high mortality and morbidity that requires immediate diagnosis and management. Nonoperative management (NOM), surgical treatment (ST), and, more recently, proximal splenic artery embolization (PSAE) have been proposed as treatment options. The goal of this study was to assess whether PSAE is safe even in high-grade ruptures. Methods: We report two rare cases of post colonoscopy splenic rupture. A systematic review of the literature from 2002 to 2010 (first reported case of PSAE) was performed and the three types of treatment compared. Results: All patients reviewed (77 of 77) presented with intraperitoneal hemorrhage due to isolated splenic trauma. Splenic rupture was high-grade in most patients when grading was possible. Six of 77 patients (7.8 %) were treated with PSAE, including the 2 cases reported herein. Fifty-seven patients (74 %) underwent ST. NOM was attempted first in 25 patients with a high failure rate (11 of 25 [44 %]) and requiring a salvage procedure, such as PSAE or ST. Previous surgery (31 of 59 patients), adhesions (10 of 13), diagnostic colonoscopies (49 of 71), previous biopsies or polypectomies (31 of 57) and female sex (56 of 77) were identified as risk factors. In contrast, splenomegaly (0 of 77 patients), medications that increase the risk of bleeding (13 of 30) and difficult colonoscopies (16 of 51) were not identified as risk factors. PSAE was safe and effective even in elderly patients with comorbidities and those taking medications that increase the risk of bleeding, and the length of the hospital stay was similar to that after ST. Conclusion: We propose a treatment algorithm based on clinical and radiological criteria. Because of the high failure rate after NOM, PSAE should be the treatment of choice to manage grade I through IV splenic

    Pseudoaneurysms of the gastroduodenal artery (GDA) are rare and mostly associated with pancreatitis. However, they can occur as a possible complication following gastric or pancreatic surgery and thus prior recognition and prompt treatment is mandatory (Lee et al., 2009 [1]). We report a case of a ruptured GDA aneurysm in a patient who underwent roux-en-y-cystojejunostomy for traumatic pancreatic pseudocyst and this has rarely been reported in the literature. Our patient presented with melena one month post operatively. CT Angiogram showed pseudoaneurysm of the GDA and the origin of right gastroepiploic artery which was embolised. Our case highlights that GDA aneurysm must be considered in the differential for a patient who presents with melena following drainage of traumatic pancreatic pseudocyst and that it can be managed successfully with angioembolization. A young boy was operated for traumatic pancreatic pseudocyst. One month later, he presented with the complaints of melena. Patient was resuscitated initially and then CT Angiogram was planned that showed pseudo aneurysm of the GDA and the origin of right gastroepiploic artery. The aneurysm was embolised and patient was sent home later on. On two months follow up the patient was doing well and had no episode of melena. GDA aneurysm are rare and should be suspected in a patient with GI hemorrhage after surgery for traumatic pancreatic pseudocyst. The investigation of choice is CT Angiography and endovascular angioembolization is the treatment modality of choice. Copyright © 2017. Published by Elsevier Ltd.

    Splenic cysts are rare lesions with around 800 cases reported in the world literature. Traditionally splenectomy was the treatment of choice. However, with the recognition of the important immunological function of the spleen, new techniques to preserve splenic function have been developed. This case emphasizes that in selected cases splenic preservation is appropriate.

    During the last two decades the reported risk of overwhelming postsplenectomy infection (OPSI) has resulted in a conservative approach to splenic trauma, with the aim of splenic salvage. The appropriateness of this strategy is now questioned. The risk of OPSI varies with age and indication for splenectomy from less than 1% in adults to more than 4% in children. Pneumococcus is the causative agent in about 60% of cases. A prerequisite for splenic preservation procedures should be a haemodynamically stable patient without other intraabdominal injuries. The benefits derived from non-operative treatment of splenic salvage procedures may be overshadowed by the potential risk of transfusion-related bacterial and viral diseases. Polyvalent pneumococcal vaccines given early after splenectomy appear to reduce the incidence of OPSI substantially.

    A 23-year-old woman who had an operation and chemo-radiation therapy for a neuroblastoma of the left adrenal gland at the age of five months developed a fever and left hypochondralgia when she was 22 years old. A splenic abscess was noted. Percutaneous drainage was done, but the splenic abscess recurred. There was no recurrence of the neuroblastoma. Conservative therapy was unsuccessful and a laparotomy was performed. Operative findings included a bulky mass at the splenic flexure which involved the spleen, pancreas tail, and jejunum. Colectomy at the splenic flexure was performed with coresection of the spleen, pancreas tail, and jejunum. The surgical specimen showed mucinous carcinoma of the splenic flexure which invaded the spleen. This case was considered to be an radiation-induced secondary colon cancer. (author)

    Splenic infarction is a rare complication of infectious mononucleosis. We describe 3 cases of splenic infarction attributed to infectious mononucleosis that we encountered within a 2-month period. We underscore the awareness of this potential complication of infectious mononucleosis and discuss the differential diagnosis of splenic infarction, including infectious etiologies. While symptomatic management is usually sufficient for infectious mononucleosis-associated splenic infarction, close monitoring for other complications, including splenic rupture, is mandated.

    Three cases (3-year-old, 51-year-old and 17-year-old males) in which splenic trauma was diagnosed by plain computed tomography (CT) are presented. CT images revealed retention of fluid in the abdominal cavity in all cases and clear splenic hematoma and laceration in one case. CT is superior in the visualization of splenic hematoma and hemorrhage in the abdominal cavity accompanied by splenic trauma. It should, however, be noted that the presence of laceration is frequently difficult to detect due to artifacts. Indication for surgery should be decided by evaluating the severity of clinical symptoms. (Namekawa, K.)

    Ninety-eight children with recent blunt abdominal trauma which initially evoked clinical suspicion of splenic injury were examined with colloid scintigraphy of the spleen and the liver using multiple imaging views and with abdominal survey. Nineteen children were, in addition, examined with tomographic scintigraphy. The clinical findings and the course of the disorder were reanalysed. Scintigraphy indicated splenic injury in 56 children and hepatic injury in another 5 children. The left lateral and the left oblique were the optimum imaging views for detecting splenic ruptures. Tomographic scintigraphy did not improve the diagnostic yield. Abdominal survey failed to indicate almost every second case of splenic rupture and provided no additional information of significance. The clinical review agreed with the scintigraphic diagnosis of splenic lesions but, in addition, it suggested possible splenic lesions in another 10 children with normal scintigraphy. This discrepancy cannot be explained as surgery was not employed; the occurrence of splenic lesions too small to become detectable at scintigraphy or to provoke clinically evident symptoms may be supposed.

    Splenic metastases occur in rare cases with a few case reports of patients in the literature. Generally, splenic metastases mean late dissemination of a disease. Solitary splenic metastases from solid tumors are extremely unusual. We report a case of a patient with ovarian mucinous cystadenocarcinoma who underwent splenectomy for isolated parenchymal metastasis. Ovarian epithelial tumors comprised most of isolated splenic metastases from gynecologic tumor. When isolated splenic recurrence is suspected on image studies and serum tumor markers, intraabdominal gross findings should be examined to exclude peritoneal carcinomatosis. If only spleen was under suspicion of recurrence of ovarian cancer, splenectomy may play a therapeutic role

    The spleen is a highly perfused organ involved in the immunological control and elimination of vector-borne pathogens (VBP), which could have a fundamental role in the pathogenesis of splenic disease. This study aimed to evaluate certain VBP in samples from dogs with splenic lesions. Seventy-seven EDTA-blood and 64 splenic tissue samples were collected from 78 dogs with splenic disease in a Mediterranean area. Babesia spp., Bartonella spp., Ehrlichia/Anaplasma spp., Hepatozoon canis, Leishmania infantum, hemotropic Mycoplasma spp. and Rickettsia spp. were targeted using PCR assays. Sixty EDTA-blood samples from dogs without evidence of splenic lesions were included as a control group. More than half (51.56%) of the biopsies (33/64) were consistent with benign lesions and 48.43% (31/64) with malignancy, mostly hemangiosarcoma (25/31). PCR yielded positive results in 13 dogs with spleen alterations (16.67%), for Babesia canis (n = 3), Babesia gibsoni (n = 2), hemotropic Mycoplasma spp. (n = 2), Rickettsia massiliae (n = 1) and "Babesia vulpes" (n = 1), in blood; and for B. canis, B. gibsoni, Ehrlichia canis and L. infantum (n = 1 each), in spleen. Two control dogs (3.3%) were positive for B. gibsoni and H. canis (n = 1 each). Benign lesions were detected in the 61.54% of infected dogs (8/13); the remaining 38.46% were diagnosed with malignancies (5/13). Infection was significantly associated to the presence of splenic disease (P = 0.013). There was no difference in the prevalence of infection between dogs with benign and malignant splenic lesions (P = 0.69); however B. canis was more prevalent in dogs with hemangiosarcoma (P = 0.006). VBP infection could be involved in the pathogenesis of splenic disease. The immunological role of the spleen could predispose to alterations of this organ in infected dogs. Interestingly, all dogs with B. canis infection were diagnosed with hemangiosarcoma in the present survey. As previously

    Purpose: To evaluate the effectiveness of partial splenic embolization (PSE) in patients with idiopathic portal hypertension (IPH) in reducing variceal bleeding episodes, splenomegaly and thrombocytopenia. Materials and methods: Six patients (2M, 4F, mean age 30.3 years) with IPH presenting with splenomegaly, thrombocytopenia and recurrent variceal bleeding were treated with PSE using gelatin sponge (four patients) or Contour particles (two patients) as embolization material. Results: PSE was performed successfully in all cases; 3F coaxial microcatheters were necessary in two patients due to extreme splenic artery tortuosity. The average amount of devascularized parenchyma at CT 1 week after PSE was 71%. Splenomegaly and thrombocytopenia improved in all cases, with a mean platelet count increase of 120000/mm{sup 3} and an average 68% reduction of spleen volume at follow up. Variceal bleeding did not recur after PSE. Esophageal or gastroesophageal varices disappeared (one patient) or significantly reduced (five patients) at endoscopic controls. No significant complications were noted. The follow up was of at least 18 months in all patients; mean follow up was 28.2 months. Conclusion: In patients with IPH PSE can be effective in preventing variceal bleedings, in reducing spleen volume and in significantly increasing platelet count; therapeutic results were durable in our population.

    Objective: To study the visualization capability and scanning technique of SCTA in celiac artery, superior mesenteric artery (SMA) and other branches. Methods: Thirty patients, with normal abdominal SCTA results, were given small injection test dose after plain scan. The abdominal aorta parallel to the body of pancreas was chosen as target vessel, the peak-time plus 2 seconds as the best delay scan time. Iodine contrast medium 90∼110 ml was injected into antecubital vein at the speed of 3.5 ml/s, then scan from cranial to caudal was performed. Pitch 1.0 and slice thickness 3.2 mm were selected as the scan parameters. Maximum intensity projection (MaxIP) was employed in all patients and shaded surface display (SSD) in 23 cases. Results: The display rate using MaxIP and SSD of celiac artery, splenic artery, common hepatic artery, proper hepatic artery and SMA were all 100%, the gastroduodenal artery 100% and 91%, the left gastric artery 83% and 87%, respectively. Conclusions: SCTA as a minimally invasive examination is a valuable method to detect and diagnose disease or variations of celiac artery, its branches and SMA. Spiral scanning technique and image processing have a decisive effect on the image quality

    Spontaneous splenic rupture not associated with previous trauma is an uncommon disease. It can appear in the course of multiple systemic diseases or over a normal splenic architecture, which is even more infrequent. An early diagnosis results mandatory, since it is a potentially fatal disease if it is not promptly diagnosed and managed. We present three cases of spontaneous splenic rupture (two sub capsular hematomas opened to peritoneum and a rupture of splenic parenchyma). One patient had infectious mononucleosis, other was in the acute phase of a chronic pancreatitis and the third one had a normal splenic architecture. We emphasize the importance of CT in the early diagnosis of this entity. (Author) 21 refs

    The management of splenic injuries has shifted from splenectomy to splenic preservation owing to the risk of overwhelming post-splenectomy infection (OPSI). This study aimed to identify the factors that determine splenectomy in patients with isolated splenic injuries, with a view to increasing the rate of splenic preservation. Files of 55 patients managed for isolated splenic injuries from blunt abdominal trauma between 1998 and 2007 were retrospectively analysed using a pro forma. Management options were classified into nonoperative, operative salvage and splenectomy. The majority of patients suffered splenic injury as a result of motor vehicle accident (MVA) trauma or falls. Splenectomy was undertaken in 33 (60%) patients, 12 (22%) had non-operative management, and operative salvage was achieved in 10 (18%) patients. Significant determinants of splenectomy were grade of splenic injury, hierarchy of the surgeon, and hierarchy of the assistant. MVA injury and falls accounted for the vast majority of blunt abdominal trauma in this study. The rate and magnitude of energy transferred versus splenic protective mechanisms at the time of blunt abdominal trauma seems to determine the grade of splenic injury. Interest in splenic salvage surgery, availability of technology that enables splenic salvage surgery, and the experience of the surgeon and assistant appear to determine the surgical management. Legislation on vehicle safety and good parental control may reduce the severity of splenic injury in blunt abdominal trauma. When surgery is indicated, salvage surgery should be considered in intermediate isolated splenic injury to reduce the incidence of OPSI.

    Full Text Available We report the case of a patient with a pseudoaneurysm of the ascending aortic clinically diagnosed 5 months after surgical replacement of the aortic valve. Diagnosis was confirmed with the aid of two-dimensional echocardiography and helicoidal angiotomography. The corrective surgery, which consisted of a reinforced suture of the communication with the ascending aorta after opening and aspiration of the cavity of the pseudoaneurysm, was successfully performed through a complete sternotomy using extracorporeal circulation, femorofemoral cannulation, and moderate hypothermia, with no aortic clamping.

    Splenic injuries can be challenging to the sports medicine physician. While these injuries are not common among athletes, they can have serious, potentially fatal consequences if not properly diagnosed and managed in a prompt and timely fashion. Currently, there are no evidence-based guidelines on returning athletes to previous levels of activity after sustaining a splenic injury. In addition, there is no consensus on follow-up imaging after injury. This article discusses the evaluation of athletes with blunt abdominal trauma for splenic injury, including the imaging, management, and current return-to-play guidelines.

    Full Text Available Renal angiomyolipoma is a hamartomatous, benign tumor composed of blood vessels, fatty tissue and smooth muscle cells, and is often detected incidentally. It can also be associated with the tuberous-sclerosis complex (TSC. Pregnancy and use of oral contraceptives are known to be associated with an increased risk of tumoral rupture and bleeding. Herein, we report a unique case of renal angiomyolipoma associated with TSC who presented with hypovolemic shock as a result of spontaneous rupture of a giant renal pseudoaneurysm, immediately after pregnancy. Emergency endovascular treatment was successful with sparing of most of the affected kidney as demonstrated by follow-up computed tomography imaging.

    Full Text Available Blunt trauma to the neck or to the chest are increasingly observed in the emergency clinical practice. They usually follow motor vehicle accidents or may be work or sports related. A wide pattern of clinical presentation can be potentially encountered. We report the uncommon case of a patient who was referred to our observation presenting with hoarseness and disphagia. Twenty days before he had sustained a car accident with trauma to the chest, neck and the mandible. Laryngoscopy showed a left recurrent laryngeal nerve palsy. Further otolaryngo-logical examination showed no other abnormality. At CT and MR imaging a post-traumatic aortic pseudoaneurysm was revealed. The aortic pseudoaneurysm was consequently repaired by implantation of an endovascular stent graft under local anesthesia. The patient was discharged 10 days later. At 30-days follow-up laryngoscopy the left vocal cord palsy was completely resolved.

    Extrarenal pseudoaneurysms of transplanted kidneys are very rare but can have devastating consequences. In the past, these extrarenal pseudoaneurysms have often led to graft loss as well as significant morbidity and mortality. The role of advanced diagnostic imaging studies and of modern radiologic interventional management has not been studied. In this case series, we present four cases of extrarenal pseudoaneurysms of transplanted kidneys, describe the clinical scenarios and imaging that led to the angiographic diagnosis, and discuss the various endovascular and surgical approaches to management.

    Splenic abcess is an uncommon complication for cancer treatment. It occurs more frequently in immunocompromised patients. They are characterized by high mortality. The classic triad (fever, pain of the left hypochondrium, and sensitive mass left) is only present in one-third of cases the clinical spectrum ranging from no symptoms to events such as fever, nausea, vomiting, weight loss, abdominal pain left, splenomegaly. Treatment options are limited, but must be discussed and adapted to the patient profile. We report the case of a 62-year-old Arabic male, diagnosed with metastatic lung adenocarcinoma, who, after several cycles of chemotherapy, presented symptoms and signs of splenic abcess. Splenic abcess is rare situation, which must be actively researched, to have access to an optimal therapeutic approach.

    A 22-year-old man complaining of persisting high fever and right hypochondralgia was admitted to our hospital for infectious mononucleosis with splenic infarction detected by computed tomography. The splenic infarction deteriorated with a marked elevation of inflammatory parameters. This necessitated the commencement of methylprednisolone pulse therapy, resulting in prompt amelioration of inflammation and a reduction in cytokine levels. Including our case, only 9 cases of mononucleosis with splenic infarction have been reported to date; however, splenic infarction should be considered because it is a significant complication of infectious mononucleosis.

    Purpose To evaluate the angiographic findings and embolotherapy in the management of traumatic renal arterial injury Methods This is a retrospective review of 22 patients with renal trauma who underwent arteriography and percutaneous embolization from December 1995 to January 2002. Medical records, imaging studies and procedural reports were reviewed to assess the type of injury, arteriographic findings and immediate embolization results. Long-term clinical outcome was obtained by communication with the trauma physicians and by clinical chart review.Results Arteriography was performed in 125 patients admitted to a State Trauma Center with suspected internal bleeding. Renal arterial injury was documented in 22 and was the result of a motor-vehicle accident (10), auto-pedestrian accident (1), gunshot (4) or stab wounds (6) and a fall (1). Percutaneous renal arterial embolization was undertaken in 22 of 125 (18%) patients to treat extravasation (11), arterial pedicle rupture (5), abnormal arteriovenous (3) or arteriocalyceal (2) communication and pseudoaneurysm (3). One of the pseudoaneurysms and one of the arteriovenous fistulae were found in addition to extravasation. All 22 patients (16 men, 6 women) were hemodynamically stable, or controlled during arteriography and embolotherapy. Selective and/or superselective embolization of the abnormal vessels was performed using coils in 9 patients, microcoils in 9 patients and Gelfoam pledgets in 3 patients. In one patient Gelfoam pledgets mixed with polyvinyl alcohol (PVA) particles were used for embolization. Immediate angiographic evidence of hemostasis was demonstrated in all cases. Two initial technical failures were treated with repeat arteriography and embolization. There was no procedure-related death. There was no non-target embolization. One episode of renal abscess after embolization was treated by nephrectomy and 3 patients underwent elective post-embolization nephrectomy to prevent infection. Follow-up ranged

    Dislocation injuries of the glenohumeral joint are common in the general public and generally are corrected without complication. One serious complication with shoulder dislocations, or the subsequent reduction, is a lesion to the axillary artery. This specific complication is most frequently seen in the elderly population, where vascular structures have become less flexible. Also, these injuries are most common in association with anterior dislocations of the shoulder. To bring awareness to the possibility of axillary artery injury with inferior dislocation of the shoulder, the treatment options, and a review. We report a 15-year-old male athlete who inferiorly dislocated his shoulder during wrestling practice. The injury was reduced at the scene with manual traction and the patient was transferred to our clinic for evaluation. The patient was determined to have a pseudoaneurysm of the axillary artery, and the history and treatment of the illness are presented. Axillary artery injuries secondary to shoulder dislocations are rare, especially in the young athlete, and proper recognition and treatment offer patients a full recovery. Copyright © 2010.

    Tuberculosis of the spleen is not exceptional. The authors report ten cases which occurred with a predominance in young male adults. All patients had at least one other site of tuberculosis without any HIV infection. All patients had focal splenic lesions in the form of scattered hypo-echogenic and hypodense nodules. These nodules had a pseudo-tumor appearance in one case. CT-guided puncture was performed in one case. Splenic tuberculosis is not as rare as is sometimes thought. The CT-guided splenic puncture is now performed routinely and remains the ideal diagnostic approach. (authors). 9 refs., 5 figs

    Fistula formation to the inferior vena cava is a rare complication of aortic aneurysm which is often misdiagnosed clinically. In one hundred of reported arteriocaval fistulae, none was originating from the right common iliac artery. We report a case of ileo-caval fistula due to a iatrogenic pseudoaneurysm. High resolution 3D imaging using breath-hold CT angiography is highly specific in identifying the location, extent of the aortocaval fistula as well as the neighbouring anatomic structures.

    Full Text Available Celiac artery shows frequent variations in its branching pattern. Knowledge of its possible variations is useful in gastric, pancreatic and hepato-biliary surgeries. During our dissection classes, we observed a rare variation of the branching pattern of celiac trunk. It divided normally into its three branches; left gastric, splenic and common hepatic arteries. Left gastric and splenic arteries were normal in their course and distribution. The common hepatic artery trifurcated to give hepatic artery proper, gastroduodenal artery and an additional right hepatic artery. The branching pattern of hepatic artery proper and gastroduodenal arteries was normal. The additional right hepatic artery gave origin to a right gastric artery and a large pancreatic branch to the head of the pancreas. It coursed parallel to the bile duct, being on its right side, passed through the Calot’s triangle and entered the right lobe of liver through the fossa for gall bladder. In the Calot’s triangle, it gave a cystic branch to the gall bladder. We discuss the clinical importance of this rare variation in this paper.

    Objective: To evaluate the clinical value of internal carotid artery occlusion in treatment of intractable epistaxis caused by carotid artery siphon traumatic lesions. Methods: A total of 37 patients with intractable epistaxis caused by traumatic carotid artery siphon pseudoaneurysm or carotid cavernous fistula were retrospectively analyzed. All the patients underwent embolization from October 1998 to June 2010, including 34 men and 3 women with the age ranged from 25 to 65 years and a average of 40 years. Only lesions were occluded in 12 cases without involving the internal carotid artery, while occlusions of internal carotid artery were performed in the rest 25 cases. Results: Thirty-six patients were cured without recurrent hemorrhage after embolization. Only 1 patient with carotid artery occlusion died 48 hours after operation. Conclusion: For patients with carotid arterial intractable epistaxis, if the elimination of the lesions is not applicable and the collateral circulation of Willis ring has a good compensation, the use of detachable balloon or coil occlusion of ipsilateral internal carotid artery is a quick and easy method to save patients' lives.

    Full Text Available Abstract Introduction Kidney transplantation can be complicated by infection and subsequent development of mycotic aneurysm, endangering the survival of the graft and the patient. Management of this condition in five cases is discussed, accompanied by a review of the relevant literature. Case presentations Five patients, three men 42-, 67- and 57-years-old and two women 55- and 21-years-old (mean age of 48 years, all Caucasians, developed a mycotic aneurysm in the region of the anastomosis between renal graft artery and iliac axes. Four patients presented with systemic fever and iliac fossa pain and one presented with hemorrhagic shock. Morphologic investigation by color doppler ultrasonography revealed a pseudoaneurysm at the anastomotic site. A combination of antibiotic therapy, surgery and interventional procedures was required as all kidney transplants had to be removed. No recurrence was recorded during the follow-up period. Conclusions A high index of suspicion is required for the timely diagnosis of a mycotic aneurysm; aggressive treatment with cover stents and/or surgical excision is necessary in order to prevent potentially fatal complications.

    Patterns for nonoperative management of pediatric blunt splenic injuries (BSIs) vary significantly within and between institutions. The indications for repeated imaging, duration of activity restrictions, as well as the impact of volume and type of trauma center (pediatric vs. adult) on outcomes remain unclear. A retrospective review of all patients younger than 16 years with BSI managed at a rural American College of Surgeons-verified adult Level II trauma center from January 1995 to December 2008 was completed. Patients were identified from the trauma registry by DRG International Classification of Diseases-9th Rev. (865.00-865.09) and management codes (41.5, 41.43, and 41.95). Variables reviewed included demographics, mechanism of injury, Injury Severity Score, grade of splenic injury, degree of hemoperitoneum, presence of arterial phase contrast blush on computed tomography at admission, admission and nadir hemoglobin level, blood transfused, length of stay, disposition, outpatient clinical and radiographic follow-up, interval of return to unrestricted activity, and clinical outcomes. During the 13-year study period, 38 children with BSI were identified. Thirty-seven (97%) were successfully managed nonoperatively. Median grade of splenic injury was 3 (range, 1-5); 73% had moderate-to-large hemoperitoneum. Median Injury Severity Score was 10 (range, 4-34). Three patients with isolated contrast blush on initial computed tomography were successfully managed nonoperatively with no angiographic intervention. One patient failed nonoperative management and underwent successful splenorrhaphy. All patients were discharged home. Thirty-day mortality was zero. Median follow-up duration was 5.5 years, with no late complications identified. Of the patients successfully managed nonoperatively, 92% had their follow-up at our institution; 74% underwent subsequent imaging, and none resulted in intervention or alteration of management plan. Pediatric BSI can be managed in adult

    Background. There is a rare association between splenic hamartomas and hematological abnormalities with, to our knowledge, only 24 reported cases in the English literature. Patients and methods. We report a case of a splenic hamartoma in a 14-year-old boy associated with membranoproliferative glomerulonephritis, multiple lobular capillary hemangiomas of the skin, hypertension, and anemia. Following imaging with ultrasonography, MRI, and nuclear scans, a hamartoma was suspected, but malignancy could not be excluded. The lesion was removed by partial splenectomy, and pathological examination confirmed the presence of a red pulp splenic hamartoma. Results. The renal, hematological, and dermatological abnormalities resolved following removal of the splenic hamartoma. This is the first reported case of a splenic hamartoma associated with renal, cutaneous, and hematological abnormalities and only the second reported case of a symptomatic splenic hamartoma treated by partial splenectomy.

    Laparoscopic distal gastrectomy has recently become accepted as a surgical option for early gastric cancer in the distal stomach, but laparoscopic total gastrectomy (LTG) has not become widespread because of technical difficulties of esophagojejunal anastomosis and splenic hilar lymphadenectomy. Splenic hilar lymphadenectomy should be employed in the treatment of advanced proximal gastric cancer to complete D2 dissection, but laparoscopically it is technically difficult even for skilled surgeons. Based on the evidence that prophylactic combined resection of spleen in total gastrectomy increased the risk of postoperative morbidity with no survival impact, surgeons have preferred laparoscopic spleen-preserving splenic hilar lymphadenectomy (LSPL) for advanced tumors without metastasis to splenic hilar nodes or invasion to the greater curvature of the stomach, and reports with LSPL have been increasing rather than LTG with splenectomy. In this paper, recent reports with laparoscopic splenic hilar lymphadenectomy were reviewed.

    Purpose: Evaluation of the use of covered stents in treating pseudoaneurysms of the cervical and intracranial/extradural carotid artery and determination of the periprocedural and short- to mid-term complication rate. Materials and Methods: 8 patients with 9 spontaneous dissecting aneurysms of the cervical carotid artery - 5 of which were symptomatic - plus one patient with ofthalmoplegia due to an aneurysm of the cavernous carotid artery were studied. While the latter was treated with a PTFE-covered balloon-mounted stainless steel stent (Jostent/Graftmaster), a self-expanding PTFE-covered Nitonol Stent (Symbiot) was used in all other cases. Intervention was performed with local anesthesia. Aspirin and Clopidogrel were both used as antiplatelet drugs. Clinical signs and symptoms and vascular imaging with DS, MR, CT angiography and ultrasound were recorded during patient follow-up, with a mean follow-up period of 14.6 months (4 - 30). Results: We were able to treat 8 out of 10 aneurysms (80 %) using covered stents. The aneurysms were immediately occluded and the associated stenoses of the parent vessel were eliminated. No clinically relevant complications occurred during the procedure or in the follow-up interval. In two cases, elongation of the carotid artery prevented the stent from being positioned over the aneurysm neck. These cases were shown to be stable with the use of antiplatelet drugs. Conclusion: Covered stents can be used in the treatment of pseudoaneurysms of the carotid artery as an alternative to long-term antithrombotic medication or surgery. In our study treatment was effective (80 %) and free of complications in the short- and mid-term follow-up. Possible indications, technique and the use of imaging modalities for patient follow-up are discussed. (orig.)

    Full Text Available A 12-year-old girl presented with a large congenital splenic cyst complicated by Salmonella organisms. After failure of conservative management and percutaneous drainage, a splenectomy was performed. An incidental splenunculus was preserved. On follow up the splenunculus had increased to normal splenic size and there was no evidence of Howell-Jolly bodies, suggesting normal splenic function.

    BACKGROUND: Delayed presentation of splenic trauma is a well described entity. METHOD: We report two patients who presented with splenic abnormality found incidentally on imaging for other medical problems. A remote history of splenic trauma was elicited during clinical evaluation; 18 months in one patient and 11 years in the second patient. Both patients underwent surgical exploration. CONCLUSIONS: Radiological investigations could not reassure us that the splenic abnormalities were benign, and their management was the subject of some debate.

    Delayed splenic rupture following conservative management of splenic injury is an extremely rare complication. We report a case of an adult patient who presented with delayed splenic rupture necessitating splenectomy, 2 months following blunt abdominal trauma. Imaging at the initial presentation demonstrated only minimal splenic contusion and the patient was discharge following 24 hours of observation. © 2014.

    Although splenic angioembolization (SAE) has been introduced and adopted in many trauma centers, the appropriate selection for and utility of SAE in trauma patients remains under debate. This study examined the outcomes of proximal SAE as part of a management algorithm for adult traumatic splenic injury compared with splenectomy. A retrospective cohort analysis was performed on all hemodynamically stable (HDS) blunt trauma patients with isolated splenic injury and computed tomographic (CT) evidence of active contrast extravasation that presented to a level 1 Trauma Center over a period of 5 years. The cohorts were defined by two separate 30 month periods and included 78 patients seen before (group I) and 76 patients seen after (group II) the introduction of an institutional SAE protocol. Demographics, splenic injury grade, and outcomes of the two groups were compared using Student's t test, or chi2 test. Analysis was by intention-to-treat. Six hundred eighty-two patients with blunt splenic injury were identified; 154 patients (29%) were HDS with CT evidence of active contrast extravasation. Group I (n = 78) was treated with splenectomy and group II (n = 76) was treated with proximal SAE. There was no difference in age (33 +/- 14 vs. 37 +/- 17 years), Injury Severity Score (31 +/- 13 vs. 29 +/- 11), or mortality (18% vs. 15%) between the two groups. However, the incidence of Adult Respiratory Distress Syndrome (ARDS) was 4-fold higher in those patients that underwent proximal SAE compared with those that underwent splenectomy (22% vs. 5%, p = 0.002). Twenty two patients failed nonoperative management (NOM) after SAE. This failure appeared to be directly related to the grade of splenic organ injury (grade I and II: 0%; grade III: 24%; grade IV: 53%; and grade V: 100%). Introduction of proximal SAE in NOM of HDS splenic trauma patients with active extravasation did not alter mortality rates at a Level 1 Trauma Center. Increased incidence of ARDS and association of

    Pseudoaneurysms of the ascending aorta after the original inclusion/wrap technique of the Bentall procedure present a difficult surgical management problem and are associated with substantial morbidity and mortality. Patients with Marfan syndrome frequently develop aneurysms and dissections that involve multiple aortic segments. We present the case of a Marfan patient who successfully underwent repair of a giant ascending aortic pseudoaneurysm and concomitant repair of an abdominal aortic ane...

    This study evaluated technical and clinical outcomes and identified factors associated with clinical success in trauma patients that underwent transcatheter arterial embolization (TAE) in a single regional hospital. A retrospective study was performed of 106 patients with a variety of trauma who were suspected of active arterial bleeding and underwent angiography. Technical success was defined as non-visualization of extravasation and pseudoaneurysm in injured arteries. Clinical success was defined as the patient was not expired within 30 days from the date of TAE. Electronic medical records were reviewed. The risk factors between groups of clinical success and failure were analyzed statistically. Technical and clinical success rates of TAE were 96% (102/106) and 70% (74/106) respectively. Of the factors we assessed, age, older than 60 years, systolic blood pressure and heart rate at admission and after TAE, and combined brain injury were statistically significant (p < 0.05). Old age, low systolic blood pressure after TAE, and combined brain injury were significant predictors of poor prognosis in multivariate analysis. TAE is an effective treatment for active arterial bleeding of the traumatic injury patient.

    Splenic and perisplenic pathology, demonstrated by CT examination in 14 septic patients, was correlated with the clinical course and with surgical and pathologic findings available. Twelve patients were intravenous drug addicts and two patients developed bacteremia associated with bacterial endocarditis. The CT fingings were divided into three groups: (1) Single wedge-shaped peripherally located defects were seen in five patients; there was good response to medical therapy without other complications. (2) Larger and/or multiple, rounded or oval lesions were present in five patients; two of these patients had splenic abscesses proven on subsequent splenectomy. (3) Multiple splenic lesions and fissures associated with perisplenic and subphrenic fluid collections were seen in four patients; infected splenic infarcts, splenic fractures, and infected perisplenic hemorrhagic fluid collections were found in this group of patients. The CT examination in septic patients can reliably demonstrate splenic and perisplenic pathology, and its appearance contributes greatly to the overall clinical assessment and surgical approach.

    We report on a 33-year-old man with symptomatic heterotopic suprarenal splenic tissue. Heterotopic splenic tissue can often be found after posttraumatic splenectomy. It is a result of autotransplantation induced by trauma (splenosis). Additionally it can grow during embryogenic development. Such an accessory spleen is found in 10-44% of all autopsies. In this case report the patient was treated by resection due to increasing flank pain and suspected neoplasm. (orig.) [de

    Full Text Available Autogenous splenic implant seems to be the only alternative for preservation of splenic tissue after total splenectomy. This work was carried out to analyze the morphologic regeneration of autotransplanted splenic tissue in Wistar rats and to determine the bacterial phagocytic function of their macrophages. We utilized an experimental model with thirty-two rats, of both sexes, submitted to total splenectomy combined with autotransplantation in greater omentum of slices of the whole spleen mass. The animals were divided into two groups: I - young rats weighing 100 to 150 g; and II - adult rats weighing 250 to 300 g. Sixteen weeks later animals were intravenously inoculated with a suspension of Escherichia coli AB1157. Twenty minutes after inoculation, the animals were sacrificed and the splenic autotransplants were removed for morphological study. There was regeneration of autotransplanted splenic tissue in all animals. A similar morphological aspect among all animals was observed, with splenic tissue showing red and white pulps, lymphoid follicles, and marginal zone, with a moderate architectural disarrangement. Macrophages containing gram-negative bacterial aggregates as well as macrophages with hemosiderin pigments within the cytoplasm were observed. Blood vessels showed preserved walls, with no signs of vasculitis or thrombosis. The present results suggest that autogenous splenic implants in the greater omentum of the rat acquire the macro- and microscopic architecture of a normal spleen, with reduced dimensions, and preserve bacterial phagocyte function.
