    Pseudoaneurysm of uterine artery during pregnancy is a very rare disease. It is mostly associated with uterine artery injury, usually occurring after proceeding conditions such as history of gynecologic operation and infection. However, the best treatment modality has not been established yet. Herein, we reported a case of spontaneous formation of uterine artery pseudoaneurysm during pregnancy treated by direct thrombin injection without any complication or recurrence.

    A 23-year-old man with post-traumatic hepatic artery pseudo-aneurysm and subphrenic liver abscess was admitted. He underwent coil embolization of hepatic artery pseudo-aneurysm. The pseudo-aneurysm was successfully obstructed and subphrenic liver abscess was controlled. Super-selective trans-catheter coil embolization may represent an effective treatment for hepatic artery pseudo-aneurysm combined with subphrenic liver abscess in the absence of other therapeutic alternatives.

    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.

    Pseudoaneurysms of the lingual artery are extremely rare and are commonly iatrogenic in nature or less frequently a result of blunt or penetrating trauma. Traditionally, these vascular abnormalities have been repaired with open or endovascular techniques. Although ultrasound-guided percutaneous thrombin injection has become a standard treatment for superficial pseudoaneurysms, there are no reports of this being used in the treatment of lingual artery pseudoaneurysms. We report the case of a 26-year-old man who suffered a penetrating head and neck injury after an improvised explosive device blast in Iraq who presented with persistent oropharyngeal swelling. Color-flow Doppler ultrasonography revealed the classic yin/yang sign of a pseudoaneurysm, and a computed tomography scan was obtained that revealed a right lingual artery pseudoaneurysm. With the lack of endovascular capabilities and the excessive risk of open surgery, thrombin was injected directly into the pseudoaneurysm under ultrasound guidance. A computed tomography scan and Doppler ultrasonography revealed complete resolution of the aneurysm. This article presents the first reported case in the English literature of a lingual artery aneurysm after penetrating trauma managed successfully with ultrasound-guided percutaneous thrombin injection.

    Surgery on the head and neck region may be complicated by vascular trauma, caused by direct injury on the vascular wall. Lesions of the arteries are more dangerous than the venous one. The traumatic lesion may cause laceration of the artery wall, spasm, dissection, arteriovenous fistula, occlusion or pseudoaneurysm.

    Subclavian artery pseudoaneurysm that induced from central venous catheterization through the internal jugular vein is relatively uncommon. However, the management of subclavian artery pseudoaneurysm remains a challenge because of their non-compressibility of deep locality and relationship to important surrounding anatomy, such as the origin of vertebral artery. In this paper, the authors report a patient with larger iatrogenic subclavian arterial pseudoaneurysm near the origin of vertebral artery, that was treated successfully by endovascular covered stent and coils.

    Objective: To evaluate the long-term effect of endovascular occlusion with microcoils on traumatic pseudoaneurysms (TPAs) in the common carotid artery in rabbits.Methods: TPAs in the right common carotid artery were surgically made in 16 rabbits. At 3-4 weeks after operation, the survived 12 models were randomly divided into a control group (n = 3 ) with no treatment and an experimental group (n = 9), in which TPAs were intraluminally embolized with microcoils and corresponding therapy was given. Three months after embolization, the TPAs were examined with digital subtraction angiography and pathology.Results: The 3 rabbits in the control group all died of rupture of TPA. Among the 9 TPAs occluded with microcoils, 4 were completely occluded, 4 were partially occluded, and 1 was excluded due to the microcoils migrating into the parent artery. Three months after embolization, the 4 TPAs which were completely occluded remained obliterated as determined by digital subtraction angiographic findings. The parent artery remained unobstructed and the structure of the TPAs were replaced by a mass of scar tissues. The 4 TPAs which were partially occluded remained unruptured and the microcoils were compressed.Conclusions: The lumen in TPA can be completely occluded by microcoils and the parent artery is unblocked.Partial occlusion of the lumen can also prevent the rupture of TPA.

  10. MRSA-Infected External Iliac Artery Pseudoaneurysm Treated with Endovascular Stenting

    International Nuclear Information System (INIS)

    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

    Full Text Available An unusual cause of vaginal beeding after total abdominal hysterectomy is being reported. Histopathology revealed adenomyosis uteri and bilateral ovarian cyst. On examination there was a single lump in the hypogastrium and left iliac fossa. Auscultation revealed a faint continuous hum. On digital rectal examination, a bulge was felt, while per vaginum examination revealed mucosal congestion and bulging of mucosa. Ultrasound revealed a mass posterior to the urinary bladder. Duplex study demonstrated the yin-yang sign suggestive of a pseudo-aneurysm .CT Angiography was confirmatory and demonstrated a pseudoaneurysm arising from the left internal iliac artery. Patient underwent surgery.Postoperative period was uneventful . The commonest cause of IIA aneurysm is atherosclerosis. Other causes are arteritis ,collagen vascular disease, infection, trauma. An important subgroup is young females, who have undergone difficult delivery, forceps delivery or caesarian section or abdominal hysterectomy IIA aneurysms are usually discovered incidentally on pelvic imaging for any other indication.

    International Nuclear Information System (INIS)

    The authors describe a hepatic pseudoaneurysm following laparoscopic cholecystectomy in a child. It arose from a hepatic artery that was ligated during surgery and was supplied by collaterals from the superior right branch. Because of the risk of hepatic infarction and recanalization of the pseudoaneurysm by new collaterals, the authors decided not to occlude the superior right branch, but to embolize the aneurysm itself with cyanoacrylate. Since the intra-arterial approach was not feasible, a transhepatic puncture was successfully performed. (orig.)

    Pseudoaneurysms of the superficial temporal artery are an uncommon vascular lesion of the external carotid system and most often the result of blunt head trauma. The frequency of pseudoaneurysms of the superficial temporal artery developing after craniotomy is exceedingly low and only a few cases have been reported. We present a case of pseudoaneurysm of this type in a 45-year-old male who underwent craniotomy for excision of meningioma. One month postoperatively, the craniotomy flap exhibited an enormous diffuse pulsate swelling. The suspected diagnosis of pseudoaneurysm arising from superficial temporal artery was confirmed on angiography. Surgical excision was done and no recurrences of the tumor or aneurysm were noted on subsequent follow up. PMID:26501064

    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. PMID:22674937

    International Nuclear Information System (INIS)

    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.

    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.)

    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 Vascular injury is one of the rare complications of primary total hip arthroplasty (THA. We report an unusual case of lobulated pseudoaneurysm arising from one of the branches of the left internal iliac artery during acetabulum preparation in THA, which was successfully treated with coil embolization and multidisciplinary care. After 6 years follow up, patient did not have any symptoms related to the hip replacement. We recommend that surgeons should be extremely cautious while drilling medial wall of the acetabulum for depth assessment. Aggressive multidisciplinary approach, including possible support from an interventional radiologist is required for the treatment of such vascular injuries.

    Acute pancreatitis is a rare phenomenon in children but its incidence seems to be increasing. In children, it is generally caused due to systemic illness, biliary disease, trauma, idiopathy and side effects of medicines like L-aspariginase. Acute pancreatitis is difficult to diagnose in children...... pseudoaneurysm due to acute pancreatitis in a 6-year-old boy with acute lymphoblastic leukaemia treated with L-aspariginase.

    A 58-year-old man with an abscess of the psoas muscle was returned to our hospital with hematemesis. Two years earlier, he had undergone coil embolization for a superior mesenteric artery (SMA) pseudoaneurysm secondary to pancreatitis. Based on the physical examination, serum amylase level, and abdominal radiographs, a diagnosis of acute exacerbation of pancreatitis and coil compaction of the SMA pseudoaneurysm was made. The patient underwent re-embolization for the coil compaction using interlocking detachable coils. His condition improved gradually, and he was discharged 3 weeks later. To our knowledge, this is the first report of coil compaction of SMA pseudoaneurysm. (orig.)

    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.

    Splenic artery aneurysms (SAAs) are the third most frequent intra-abdominal aneurysm, following abdominal aorta and iliac artery aneurysms. SAAs are classified according to their involvement of arterial wall layers: true aneurysms involve all 3 layers (intima, media, and adventitia), and pseudoaneurysms involve only one or two. Herein we present a new case of giant pseudo SAA. A 65-year-old female patient with a pancreatic mass and iron deficiency was referred to our clinic for further investigation. Abdominal ultrasonography, contrast-enhanced CT and magnetic resonance imaging showed a lesion resembling a subcapsular hemangioma in the spleen, and aneurysmatic dilation of the splenic artery with a diameter of >5 cm. The large size of the aneurysm and the clinical findings were indications for surgical treatment. The patient underwent en bloc resection of the spleen, distal pancreas, and aneurysmatic segment of the splenic artery. The patient remains complication-free 2 months after the operation. Spontaneous rupture is the most important life-threatening complications of giant SAAs. Therefore, all symptomatic patients with SAA should be treated, as well as asymptomatic patients with lesions ≥2 cm, who are pregnant or fertile, have portal hypertension, or are candidates for liver transplantation. Despite advances in endovascular techniques, conventional abdominal surgery remains the gold standard for treatment. PMID:26595501

    Pseudoaneurysm resulting from hysteroscopic myomectomy is a rare clinical situation, and interventional radiologists are not traditionally involved in the management. To our knowledge, endovascular treatment of a pseudoaneurysm resulting from hysteroscopic myomectomy has not yet been reported in the English-language literature. Here, two such cases are reported, including one of a woman who later became pregnant. The case is unique because little is known about the influence of unilateral coil embolization of the uterine artery on fertility.

    We report a rare case of postoperative pseudoaneurysm of the gastroduodenal artery following radical gastrectomy.Surgical trauma to the gastroduodenal artery during regional lymphadenectomy was considered as the cause of the postoperative pseudoaneurysm. The pseudoaneurysm was successfully managed by ligating the bleeding vessel. We should consider the possibility of pseudoaneurysm formation in a patient with gastrointestinal bleeding in the postoperative period following radical gastrectomy with regional lymph node and perivascular lymphatic dissection.

    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.

    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.

    Endovascular stent graft repair of traumatic vessel injuries is gaining worldwide acceptance as a minimally invasive alternative to open surgical repair. However, effective endovascular repair fails if the aneurysm is not completely excluded. Conversion to open surgery may be unavoidable in such cases. Herein we describe the case of a 45-year-old man who was referred to our hospital with a pseudoaneurysm of the proximal brachiocephalic artery caused by biopsy during diagnostic medianoscopy. The pseudoaneurysm was primarily treated by stent-graft implantation into the proximal brachiocephalic artery. As a result of the unfavorable location of the lesion exclusion of the aneurysm failed and the initial therapy had to be extended to open reconstruction of the brachiocephalic artery. A bypass procedure from the aortic arch to the right common carotid artery was performed with reinsertion of the right subclavian artery to exclude the pseudoaneurysm.

    A 43-year-old female with history of systemic lupus erythematosus, prior cytomegalovirus esophagitis treated with ganciclovir, and long segment Barrett's esophagus (Prague class C8 M9) with high grade dysplasia treated with radiofrequency ablation presented to the hospital with hematemesis. An upper gastrointestinal endoscopy showed multiple esophageal ulcers with active arterial spurting which could not be controlled with endoscopic interventions including placement of hemostatic clips. An emergent angiogram demonstrated actively bleeding saccular dilations (pseudoaneurysms) in the esophageal branches of the lower thoracic aorta as well as left gastric artery for which gelfoam and coil embolization was initially successful. Due to recurrence of massive bleeding, she subsequently underwent emergent esophagectomy and bipolar exclusion. Pathology demonstrated submucosal hemorrhage, esophagitis with dysplastic Barrett's mucosa, and an ulcer containing cytomegaloviral inclusions. We report the first case of arterial bleeding from periesophageal pseudoaneurysms as well as use of angiographic embolization for arterial bleeding in the esophagus.

    We report our experience with a case of emergent endovascular treatment of a large ruptured pseudoaneurysm of the common iliac artery. A 65-year-old male was admitted to the surgical department in hypovolemic shock, due to active retroperitoneal bleeding. A computerized tomography scan with intravenous contrast revealed a ruptured gigantic pseudoaneurysm of the right common iliac artery, with a maximal diameter of 7 cm and retroperitoneal hematoma. An intraoperative angiogram revealed active extravasation through the neck of the pseudoaneurysm, which was successfully sealed with the placement of a stent graft (Medtronic Endurant(®))limb component. Infection of the pseudoaneurysm sac after one month was successfully treated with catheter drainage. No shortterm relapse occurred. Endovascular management should be part of the basic surgical armamentarium on emergent basis, since it provides a fast and safe solution, especially when a patient's co-morbitities preclude open management and hemodynamic and anatomical status allows endovascular treatment.

    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.

    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

  1. Iatogenic pseudoaneurysm of the brachial artery in a child

    International Nuclear Information System (INIS)

    Arterial aneurysms are rarely encountered in children. When they are, the existence of an underlying disease or a history of previous infection or trauma should be suspected since the majority them are acquired. Pseudo aneurysms or false aneurysms are a consequence of the rupture of the arterial wall after accidental injury or a iatrogenic lesion. We present a case of a pseudoaneurysm of the brachial artery secondary to repeated attempts at venipuncture in a 3-month-old infant. We show the plain radiography and duplex Doppler color Doppler ultrasound findings which, in the clinical context of the patient, were sufficient for diagnosis, making it unnecessary to perform arteriography prior to surgical treatment.

    We present a 71-year-old woman with spontaneous perinephric hematoma due to a rupture of pseudoaneurysm of the right renal artery on the fourth day after radical cystectomy and bilateral ureterocutaneostomy for bladder cancer. This patient received steroid therapy for chronic rheumatoid arthritis for several years. The digital subtraction angiography of the right renal artery showed two pseudoaneurysms in the anterior inferior segmental branch and the posterior inferior segmental branch. Transarterial coil embolization of the right renal artery proximally and distally to the two aneurysms was performed without complications. Moreover, the additional angiography showed typical string-of-beads appearance and small aneurysms in abdominal visceral arteries, suggesting segmental arterial mediolysis (SAM) as a possible etiology. Differential diagnoses of SAM are discussed.

    The complications of pancreatitis, such as pseudocyst or abscesses, are well known to radiologists. Yet formation of a pseudoaneurysm of the short gastric artery is an uncommon complication of acute pancreatitis. It is also very rare for a psuedoaneurysm of the short gastric artery to cause splenic vein occlusion and the final result is gastric varices. We report here on a case that showed the dramatic effect of embolotherapy for a pseudoaneurysm of the short gastric artery that caused gastric variceal bleeding

    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.

    Medical ultrasound imaging with Doppler plays an essential role in the diagnosis of vascular disease. This study intended to review the clinical use of "to-and-fro" waveform at duplex Doppler ultrasonography(DDU) in the diagnosis of pseudoaneurysms in the arterial vessels of upper and lower extremities, abdominal aorta, carotid and vertebral arteries as well as to review our personal experiences of "to-and-fro" waveform at DDU also. After receiving institutional review board approval, an inclusive literature review was carried out in order to review the scientific foundation of "toand-fro" waveform at DDU and its clinical use in the diagnosis of pseudoaneurysms in various arterial vessels. Articles published in the English language between 2000 and 2013 were evaluated in this review study. Pseudoaneurysms in arterial vessels of the upper and lower extremities, abdominal aorta, carotid and vertebral arteries characterized by an extraluminal pattern of blood flow, which shows variable echogenicity, interval complexity, and "to-and-fro" flow pattern on color Doppler ultrasonography. In these arterial vessels, Duplex ultrasonography can demonstrate the degree of clotting, pseudoaneurysm communication, the blood flow patterns and velocities. Spectral Doppler applied to pseudoaneurysms lumen revealed systolic and diastolic turbulent blood flow with traditional "toand-fro" waveform in the communicating channel. Accurate diagnosis of pseudoaneurysm by spectral Doppler is based on the documentation of the "to-andfro" waveform. The size of pseudoaneurysm determines the appropriate treatment approach as surgical or conservative.

    Renal artery anastomotic pseudoaneurysms, an uncommon complication of transplantation, may result in aneurysm rupture and loss of allograft. We report the case of 50-year-old female with back pain 3 weeks post renal transplantation. CT scan revealed transplant renal artery anastomotic pseudoaneurysm arising from anastomosis of two renal arteries joined together to form a single renal artery that was joined to the aorta. Successful endovascular treatment was achieved with covered stents, resulting in preserved renal function. Follow-up ultrasound at one-day post procedure and CT at 2 months revealed satisfactory renal perfusion with no pseudoaneurysm. Endovascular treatment of transplant renal artery pseudoaneurysms with covered stent and ostial flare balloon technology may be preferred in patients with extensive prior pelvic surgery, as illustrated in this case.

    A 35-year-old patient was brought to the emergency department referring dysarthria, left ear tinnitus for 5 min, and short-lasting blindness, with headache in the 45 min before the clinical presentation. In the magnetic resonance imaging, an acute-subacute lesion in the cerebellum right-anterior lobe (in the territory of the cerebellum anterior artery) and a dilatation near the ostium of the right vertebral artery were seen. For a better assessment, an Angio-CT was done, showing a 9-mm saccular pseudoaneurysm of the right vertebral artery close to the origin of the vessel, without being able to determine if it had been caused because of a dissection. The rest of the study (cerebral vessels and supra-aortic vessels) showed no disorders. He was operated under local anesthesia and sedation a week after the onset of the symptoms. Through a 0.014 wire, a Biotronik PK Papyrus balloon-expandable covered cobalt-chromium stent was deployed covering the hole in the artery. Antiplatelet drugs were prescribed, and the patient was discharged 24 hr after surgery. He has remained symptom free since then. PMID:25770383

    Full Text Available Background: Delayed intra-abdominal bleeding related to hepatic artery pseudoaneurysm is a potentially lethal complication after pancreaticoduodenectomy for pancreatic cancer. Locally advanced tumors, which result in vessel erosion or extensive operative skeletonization, may contribute to weakness of the arterial wall. Reoperation is often technically difficult with high rate of mortality; therefore, alternative less invasive options are ideal. Aims: The study was to present an alternative endovascular treatment of a large hepatic artery pseudoaneurysm after pancreatic resection for locally advanced multicystic adenocarcinoma. Materials and Methods: Transcatheteric mesenteric angiography with deployment of detachable coils in the pseudoaneurysm sac was utilized to manage the hepatic artery pseudoaneurysm. Results: Completion angiography confirmed cessation of contrast enhancement in the pseudoaneurysm sac with preservation of normal antegrade hepatic artery flow. Conclusion: Minimally invasive angiographic technique is the preferred treatment for hepatic artery pseudoaneurysm after pancreatic resections.

    Large cerebral aneurysms of the basilar apex are difficult to treat. Recently, endovascular treatment has mitigated much of the morbidity associated with treating these lesions. However, the morphology of aneurysms of the vertebrobasilar system can preclude endovascular treatment. Rapid ventricular pacing (RVP) facilitates open surgical treatment of cerebral aneurysms. It can assist in reducing the pressure of the neck of the aneurysm, allowing safe application of a clip. The authors present a case of a pediatric patient who developed a basilar artery pseudoaneurysm that required surgery. Given the large size of the aneurysm, RVP was performed, allowing the surgeons to dissect the dome of the aneurysm from the surrounding tissue and pontine perforating branches away from the lesion to safely clip the lesion. The patient had an uneventful recovery. To the authors' knowledge, this represents the first known case of RVP to aid in basilar artery clip occlusion in a pediatric patient.

    Pseudoaneurysm of the pancreas is a severe complication secondary to pancreatitis. The splenic artery is most often involved, followed by the pancreaticoduodenal vessels and the gastroduodenal artery. Selective arteriography is considered the method of choice in preoperative diagnosis. In a patient with chronic pancreatitis angio-CT and ultrasound enable a definitive diagnosis of pseudoaneurysm of the splenic artery. (orig.).

    PurposeTo assess the role and effectiveness of percutaneous arterial embolization (TAE) in patients with hemodynamic instability due to hypovolemic shock secondary to ruptured splanchnic artery pseudoaneurysms (SAPA).Materials and MethodsSeventeen patients (11 men, 6 women; mean age, 53 years) with hemodynamic instability (systolic blood pressure <90 mmHg) due to hypovolemic shock secondary to ruptured SAPA were treated by TAE. 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 %. Our results suggest that TAE should be the favored option in patients with hemodynamic instability due to ruptured SAPA.

    AIM: To evaluate the effects of extrahepatic collaterals to the liver on liver damage and patient outcome after embolotherapy for the ruptured hepatic artery pseudoaneurysm following hepatobiliary pancreatic surgery.METHODS: We reviewed 9 patients who underwent transcatheter arterial embolization (TAE) for the ruptured hepatic artery pseudoaneurysm following major hepatobiliary pancreatic surgery between June 1992 and April 206. We paid special attention to the extrahepatic arterial collaterals to the liver which may affect post-TAE liver damage and patient outcome.RESULTS: The underlying diseases were all malignancies, and the surgical procedures included hepatopancreatoduodenectomy in 2 patients, hepatic resection with removal of the bile duct in 5, and pancreaticoduodenectomy in 2. A total of 11 pseudoaneurysm developed: 4in the common hepatic artery, 4 in the proper hepatic artery, and 3 in the right hepatic artery. Successful hemostasis was accomplished with the initial TAE in all patients, except for 1. Extrahepatic arterial pathways to the liver, including the right inferior phrenic artery, the jejunal branches, and the aberrant left hepatic artery,were identified in 8 of the 9 patients after the completion of TAE. The development of collaterals depended on the extent of liver mobilization during the hepatic resection,the postoperative period, the presence or absence of an aberrant left hepatic artery, and the concomitant arterial stenosis adjacent to the pseudoaneurysm. The liver tolerated TAE without significant consequences when at least one of the collaterals from the inferior phrenic artery or the aberrant left hepatic artery was present. One patient, however, with no extrahepatic collaterals died of liver failure due to total liver necrosis 9 d after TAE.CONCLUSION: When TAE is performed on ruptured hepatic artery pseudoaneurysm, reduced collateral pathways to the liver created by the primary surgical procedure and a short postoperative interval may

    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 atlantoaxial complex,iatrogenic VAI will result in catastrophic consequences 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 postoperative computed angiography is very helpful to diagnose the exact site of VAI and the combination of endovascular coil occlusion as well as external local compression can further prevent bleeding and abnormal vertebral artery flow in the pseudoaneurysm.However,patients treated require further follow-up to confirm that there is no recurrence of the pseudoaneurysm.

    2005-01-01

    Full Text Available CONTEXT: Pancreatic pseudoaneurysm rupture is a rare complication of chronic pancreatitis, with severe prognosis and high mortality. Angiography is usually required for confirmation of the diagnosis, but transabdominal ultrasound and CT angiography are useful noninvasive diagnostic methods. CASE REPORT: We present the case of a 66-year-old patient with a large pancreatic pseudoaneurysm of the superior mesenteric artery complicated with obstructive jaundice. Transabdominal ultrasound with color and power Doppler showed a large pancreatic head pseudoaneurysm that communicated directly to the superior mesenteric artery. Presence of a spinning blood flow inside the pseudoaneurysm was visualized by color Doppler, with evidence of bidirectional flow in the pseudoaneurysm neck that was showed by Doppler spectral analysis. The contrast-enhanced helical computer tomography with multiplanar sagittal and the 3D reconstruction of coronal images confirmed the communication of the pseudoaneurysm with the superior mesenteric artery. The patient was scheduled for selective angiography and embolization. However, clinical evolution was rapidly deteriorating, with collapse, hemorrhagic shock and massive hemorrhage. The patient was operated on and subsequently died despite three days of intensive care, due to disseminated intravascular coagulation and multiorgan failure. CONCLUSION: Non invasive imaging methods consisting of transabdominal ultrasound with color Doppler and contrast-enhanced computer tomography with sagittal reconstruction of coronal images were very useful in the establishment of the diagnosis of pancreatic pseudoaneurysm of the superior mesenteric artery complicated with cholestatic jaundice. However, these imaging methods do not obviate the need for diagnostic and therapeutic angiography, eventually followed by surgical intervention in cases of recurrent bleeding or hemodynamic unstable patients.

    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.)

    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.

    Objective:To retrospectively compare the efficacy and safety of ultrasound-guided thrombin injection (UGTI) with ultrasound-guided compression repair (UGCR) in patients with postcatheterizational femoral arterial pseudoaneurysms (PSA). Methods: Thirty patients of this iatrogenic PSA [8males, 22 females, average age (66.5± 5.2) years] in our nstitution from 1997 to 2004 were retrospectively analyzed. Among them, 11 patients were treated with UGCR, 2 under continuous ultrasonographic (US) guidance and 9 under the guidance of femoral arterial bruit auscultation and dorsalis pedis artery palpation. Because UGCR was failed in 5 patients, consecutively 24 patients were treated with UGTI. Wine thrombin solution at a concentration of 200 U/ml was injected percutaneously using 22-25 gauge needles under color Doppler US. Demographics, clinical variables, pseudoaneurysm characteristics, and results of the 2 groups were compared by using Fisher's exact test and Student's t test. Results: The initial success rate of UGCR was 36.4% (4/11) nd the overall success rate was 45.5% (5/11). Ten of 11 patients suffered from local pain during the compression, but there was no any complication in UGTI group. The average dose of injected thrombin was (180±82) U for PSA of a single loculus and (315±150) U for multiloculated PSA. The initial success rate of UGTI was 89.5% (17/19) and the verall uccess rate was 100% (24/24). Conclusion:UGTI offers a safe, quick and effective means of definitively treating femoral pseudoaneurysms and seems superior to UGCR. The amount of thrombin applied on our people seems smaller compared with others' work.

    A 37-year-old man who recently underwent aortic valve replacement after endocarditis presented with cardiogenic shock. A large expansile pseudoaneurysm was subsequently discovered using multiple imaging modalities. Although transesophageal echocardiography is important in diagnosing valve endocarditis, coronary CT angiography of prosthetic valves is feasible and image quality is good. In this case, coronary CT angiography allowed for better understanding of transesophageal echocardiography images and earlier diagnosis of coronary involvement as cause for left ventricular dysfunction.

    Pseudoaneurysm of the cervical internal carotid artery is a very rare, potentially fatal complication of a neck space infection in children associated with high mortality and morbidity. A 3-year-old boy presented with spontaneous massive epistaxis 45 days after a deep neck space infection caused by a peritonsillar abscess. During nasopharyngeal packing, he evolved with cardiac arrest. Intra-arterial angiography was then performed that revealed a large pseudoaneurysm. Endovascular treatment using detachable balloons achieved complete exclusion of the pseudoaneurysm. The child made an uneventful recovery and was discharged with mild left hemiparesis and no deficit of sensory or cognitive functions. Pseudoaneurysms of the internal carotid artery after a deep neck space infection can be associated with delayed and potentially fatal massive epistaxis. Furthermore, a regional (ie, extranasal) blood vessel should be promptly investigated when there are signs of hypovolemic shock. A high level of suspicion and definitive treatment are essential for successful management of these patients.

    Arthroscopy of the foot and ankle is a common orthopedic procedure with low complication rates. Arterial injuries from these procedures are an even more rare subset of the complications. Hemophilia A is a genetic disorder of aberrant coagulation, which leads to increased risk of bleeding even after minor trauma. We present the second case of anterior tibial artery pseudoaneurysm formation secondary to ankle arthroscopy in a hemophiliac patient and suggest that these individuals are at higher risk for developing complications associated with arterial injury. Furthermore, potential risk factors include port placement, anatomic variation of the vessels, and nature of the arthroscopic procedure. We recommend steps to prevent complications in hemophiliac patients. PMID:27174350

    Background: Superficial temporal artery (STA) pseudoaneurysms have been reported in the literature since the mid of seventeenth century from Bartholin, however, there is an increasing number of cases, suggesting a diversity of etiological factors. Among these, traumatic events, even of an iatrogenic nature, have been identified as causative factors for nonspontaneous STA pseudoaneurysms. Regional pain and tenderness, troublesome pulsations of the mass, cosmetic concerns as well as the risk of bleeding warrant a thorough evaluation and a definite interventional approach to the condition. Case Description: A 21-year-old Caucasian male searched medical advice for a growing, tender, and pulsatile mass on his right temple, with isolated and short episodes of lancinating sensations, after sustaining a blunt trauma following a hit with a stick half a year before the admission. Enhanced cranial computed tomography and angiography confirmed the diagnosis of an STA pseudoaneurysm. A direct percutaneous aspiration, as well as ultrasonography, was performed prior to the neurosurgical intervention, with the complete removal of the mass. Conclusions: STA pseudoaneurysms require a careful evaluation and a conclusive approach in order to avoid the risk of a growing mass and other nonremote complications such as bone erosions and bleeding. Different treatment options are available, including endovascular obliteration and embolization, however, surgical removal after ligation of the afferent and efferent segments of the vessel seem to be highly effective.

    Arterial pseudoaneurysm of the lower limb is an infrequent entity, particularly in the infrapopliteal segment. It is commonly associated to vascular repairs or follows a localized arterial lesion, a fracture or a surgical procedure. There is little information in Mexico about this entity in cases involving the anterior tibial artery, and secondary to trauma and osteosynthesis. Given that sudden bleeding due to rupture of the pseudoaneurysm is a possible catastrophic outcome for the viability of the segment, it is important to timely detect and diagnose the pseudoaneurysm. Treatment indications contained in the international literature are controversial. Solution-oriented approaches may be either surgical or endovascular. Current reports show that the best treatment option is an autologous saphenous vein graft, which maintains blood flow and minimizes the risk of peripheral ischemia. The purpose of this paper is to report the case of a patient who sustained the above mentioned complication and provide a literature review. This topic should be further investigated, as this condition may go unnoticed in a large number of cases, given that its symptoms are silent. PMID:27627775

    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

  18. Pseudoaneurysm of the internal carotid artery after shrapnel injury in World War II. Demonstration by CT angiography with 3D MIP reconstruction

    International Nuclear Information System (INIS)

    A case of pseudoaneurysm of the left internal carotid artery (ICA) after shrapnel injury is demonstrated by intra-arterial digital subtraction angiography (DSA) and computed tomography angiography (CTA) with subtraction technique. Although the pseudoaneurysm was well demonstrated by intra-arterial DSA, CTA was the only modality to demonstrate the three-dimensional shape of the perfused part of pseudoaneurysm and the aneurysmal neck, which affected the therapeutic strategy. The CTA technique is useful in the assessment of large pseudoaneurysms and for therapeutic planning. (orig.)

    Full Text Available We report a case of posttraumatic false aneurysm of popliteal artery after a total knee arthroplasty in an 82-year-old woman. This case is characterized by the distinct history of trauma to the popliteal fossa in the immediate postoperative period and the location of false aneurysm. In addition, the clinical symptoms were similar to those of deep vein thrombosis. The ultrasonographic examination and computed tomography (CT angiography confirmed the diagnosis on 6 th day after the surgery. Ultrasonographic examination 1 day later revealed no increase in the size of false aneurysm. She was treated with open surgical repair. Presenting the difficulty in the diagnosis, unusual location, etiology, and its management is the intention of this case report.

  20. Extrahepatic Pseudoaneurysms and Ruptures of the Hepatic Artery in Liver Transplant Recipients: Endovascular Management and a New Iatrogenic Etiology

    International Nuclear Information System (INIS)

    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.

    We present the case of a 65-year-old gentleman, who presented with a symptomatic pseudoaneurysm of the right common carotid artery. Because of high surgical risk, endovascular approach was decided upon. However, taking hardware across the lesion via the aortic arch provided us with insurmountable difficulties. Therefore, a hybrid approach was resorted to, in which an arteriotomy was done in the carotid artery followed by direct implantation of the stent. We were thus able to create a favorable trade-off between the high surgical risk of a full surgical procedure and the peri-operative benefit of an endovascular approach.

    Full Text Available Abstract Aim Brief case report of the treatment of a large axillary artery pseudoaneurysm after a pacemaker using a left brachial cutdown and a retrograde delivery of a covered stent using ultrasound and fluoroscopic guidance. The patient's renal function precluded the use of contrast materials. Case Report A 77 years old man presenting with acute renal failure and haemoglobin decrease arrived with an expanding pseudoaneurysm of the left axillary artery from a pacemaker placement. Considering the site of the lesion and patient's comorbidities, under echographic control, a Hemobahn® stent-graft was placed; fluoroscopy assisted manipulation of guidewires and sheaths into the aortic arch. The procedure was successfully ended without any complications. At 8 months the stent graft was still patent. Conclusion Ultrasound guidance may represent an alternative for pseudo-aneurysm exclusion without any use of contrast medium, especially in those patient where lesions are easily detectable using ultrasonography and when comorbidities contraindicate aggressive surgical or angiographic approach.

    Pancreatitis is a known cause of pseudoaneurysms of the peripancreatic arteries, which can rarely rupture into various adjacent structures and become a source of life-threatening bleeding. The management is challenging and requires an individualised approach and multidisciplinary care. Herein, we present the case of a 24-year-old man in whom a splenic pseudoaneurysm ruptured into the adjacent infected pseudocyst, communicating with the colon by a fistulous tract, causing massive lower gastrointestinal bleeding. This was successfully managed by transcatheter arterial embolisation (TAE).

    Pseudoaneurysms of the lower limb are rare and frequently iatrogenics complications. Closed traumas are likely to generate lesions of the arterial wall, which generally become symptomatic at a later stage. The diagnosis of such vascular lesion is difficult because the symptomatology and the onset can be delayed. We herein report the case of a 15-year-old patient in whom the diagnosis of pseudoaneurysm of the anterior tibial artery was made 5 months after a non-displaced closed fracture of the tibial shaft. The radiographs were evocative of a malignant bone tumor. The study of vessels by a contrast-enhanced CT-scan enabled us to diagnose the pseudoaneurysm. Before the occurrence of late onset swelling, a history of trauma must be sought, even old. PMID:27447879

    A serious complication of laparoscopic sleeve gastrectomy (LSG) is bleeding that is primarily located along the staples lines. Bleeding may be due to several causes, including hematomas, trocar sites, or visceral pseudo-aneurysms. We reported here a case of bleeding related to a pseudo-aneurysm of the gastro-omental artery. An LSG was performed on a 43-year-old woman (BMI = 46 kg/m2) without apparent surgical complications. Fifteen days later, she was admitted to the emergency department for hematemesis and symptoms of hemorrhagic shock. Abdominal computed tomography angiography revealed blood in the stomach, without a digestive leak, and active bleeding from a pseudo-aneurysm of the gastro-omental artery. An arterial embolisation was performed with the sandwich technique and angiographic guide wires and the placement of several detachable coils. The patient was discharged two days later. We demonstrated for the first time that post-LSG bleeding may involve a pseudo-aneurysm of the gastro-omental artery.

    Full Text Available Abstract We report a case of a 26-year-old female, who presented at 34 weeks of an uncomplicated pregnancy with an acute ST elevation anterior wall myocardial infarction. Cardiac catheterization suggested a left main coronary artery dissection with pseudoaneurysm formation. The patient's course was complicated by congestive heart failure. She was initially managed conservatively by a multidisciplinary team including heart failure specialists, obstetricians, and cardiovascular surgeons. 4 days after admission, her LMC was imaged by dual-source 64 slice Cardiac computed tomography, coronary dissection was identified extending to the lumen, and the presence of pseudoaneurysm was confirmed. She underwent subsequently a staged procedure, which included placement of an intra-aortic balloon pump, cesarean section, and coronary artery bypass grafting. This case illustrates the utility of coronary artery CT imaging to assess the complexity and stability of coronary artery dissections, thereby helping to determine the need for, and timing of revascularization procedures.

    A pseudoaneurysm is an uncommon but important life threatening complication of chronic pancreatitis. The arteries most commonly affected by a pseudoaneurysm are (in decreasing percent occurrence), the splenic (40%), gastroduodenal (30%), pancreaticoduodenal (20%), gastric (5%), hepatic (2%), and others (superior mesenteric, jejunal, ileocecal, and aorta) (1-3%). Thrombosis of the splenic or portal vein is another important complication of chronic pancreatitis. In this case report, we present a rare complication in the form of a right hepatic artery pseudoaneurysm which developed within the thrombosed right portal vein of a 35-year-old woman afflicted with chronic pancreatitis.

    A 41-year old alchoholic male with a history of chronic pancreatitis was admitted for nausea, vomiting and weight loss. Angiogram was performed and demonstrated an aneurysmal sac with a narrow neck originating from the inferior aspect of the distal portion of the proper hepatic artery. The origin of the pseudoaneurysm was covered with a 5 mm × 2.5 cm Viabahn cover stent (Gore). A repeat angiogram showed some leak and a second stent (6 mm × 2.3 cm)was deployed and overlapped with the first stent by 3 mm. Contrast was injected and a repeat angiogram demonstrated complete exclusion of the aneurysm. A repeat computerized axial tomography (CAT) scan of the abdomen after 24 h showed successful stenting. The patient had an uneventful post-operative course.

    Mediastinal pancreatic pseudocyst (MPP) is a rare, but known, complication of both acute and chronic pancreatitis. Most pseudocysts are associated with alcoholic pancreatitis. Recent advances in endoscopic techniques have shown promising results, with reduced chances of infection and recurrence than with percutaneous drainage, but limited availability restricts widespread use. Left gastric artery pseudoaneurysm with mediastinal pseudocyst has not been described in the literature to date. We report a successful resolution of hemorrhagic MPP with embolization of pseudoaneurysm and percutaneous trans-hepatic pseudocyst drainage. PMID:25502760

    We discuss the case of an independent 80-year-old Caucasian woman, being treated with new oral anticoagulants for a previous deep vein thrombosis, who had fallen on her right shoulder. She made a delayed presentation to the emergency department with a wrist drop in her right dominant hand. She had right arm bruising with good distal pulses but had a global neurological deficit in the hand. Plain radiographs of the shoulder, humerus, elbow, forearm and wrist demonstrated no fractures. MRI showed a significant right axillary lesion distorting the surrounding soft tissues, including the brachial plexus, and CT with contrast confirmed this to be a large axillary pseudoaneurysm. This was treated with an endovascular stent resulting in slightly improved motor function, but the significant residual deficit required subsequent rehabilitation to improve right upper limb function.

    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.

    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.

    The aim of this study was to evaluate the efficiency and safety of ultrasound-guided thrombin injection on femoral pseudoaneurysm (FPA) as compared to ultrasound-guided local oppression. Eleven cases of FPA were enrolled and 7 cases received ultrasound-guide thrombin injection (injection group), and the remaining 4 cases were treated with local oppression (oppression group). Efficiency and safety were analyzed by ultrasound and subsequent follow-up. The results showed that 1 case relapsed in oppression group while no relapse occurred in thrombin injection group. Ultrasound-guided thrombin injection is better for treatment of FPA in terms of effectiveness and safety.

    Pseudoaneurysm is a known complication of pancreatitis associated with significant mortality and morbidity. Imaging plays an important role in the diagnosis and management. Computed tomography(CT) helps localize the lesion and the severity of the background pancreatitis but digital subtraction angiography with coil embolization is recommended to avoid bleeding and inadvertent surgery. However, in cases where angiographic coil embolization is not feasible due to technical reasons, thrombin injection via CT or ultrasound guidance remains a viable option and often described in literature. In this series, effort has been made to highlight the role of endoscopic ultrasound guided thrombin instillation especially in patients with poorly visualized pseudoaneurysm on ultrasound thereby avoiding surgery and the associated mortality and morbidity.

    Objective To evaluate the value of the endovascular interventional therapy in treatment of splenic artery an-eurysms and pseudoaneurysms. Methods Sixteen patients with splenic artery aneurysms (n - 10) and false aneurysms (n=6) proveded by color doppler ultrasound, CT and DSA angiography were collected in the study. Embolization with coils were carried out to the artery aneurysms or parent artery in 14 cases. Coils were deployed into the aneurysms assisted by stents in 2 case. Routine blood tests and serum amylase were checked at 3 and 7 days after the procedure. Enhanced CT was performed at 7 days, 3 and 6 months after the procedure. Results The splenic artery has been embolized successfully in 14 cases. The aneurysms and pseudoaneurysms in all patients were not enhanced on CT angiography at 3 or 6 months after embolization. Complete aneurysms thrombosis and normal splenic artery branching has been showed on CT images 3 or 6 months after the stents and coils implanted in 2 cases. Low grade fever and bellyache were occurred after embolization in 7 and 8 cases respectively, which were relieved after 3 to 5 days. Transient elevation of serum aniylase was recovered in 1 week in 5 patients.

    Aortic coarctation is a frequent congenital defect requiring early surgical treatment. Late complications of these surgical procedures can be fatal as in the case of a ruptured anastomotic pseudoaneurysm. We present a case of a 49-year-old man presenting with hemorrhagic shock due to this complication who was successfully treated by endovascular techniques with implantation of two stent grafts. This case illustrates the fact that endovascular aortic repair is feasible, certainly less invasive and very efficient for this type of complication when used in an experienced center.

    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

    To evaluate and describe the efficacy and side effects of a percutaneous thrombin injection under ultrasonography guidance for the treatment of iatrogenic pseudo aneurysms Eighteen consecutive iatrogenic pseudo aneurysm cases were treated with a thrombin injection. The thrombin was injected into the pseudo aneurysm cavity using a 22-gauge needle under ultrasonographic guidance. The causes of the pseudo aneurysms are as follows: post coronary angiography (9 cases), percutaneous coronary balloon angioplasty (5 cases), cerebral angiography (1 case), transhepatic chemo embolization (1 case), percutaneous trans femoral arterial stent insertion (1 case) and bone marrow aspiration for a marrow transplant (1 case). Only one case required a secondary thrombin injection due to recurrent flow in the pseudo aneurysm lumen, which was detected at the follow up Doppler ultrasound. Other seventeen cases were successfully treated on the first trial. There were no technical failures or complication related to the procedure. The average amount of thrombin injected was 733 IU. Nine out of 18 treated patients (50%) showed mild reactions to the thrombin including mild fever (4 cases), chilling sensation (3 cases), a chilling sensation with mild dyspnea (1 case), mild chest discomfort (1 case) after the thrombin injection. All these side effects were transient and improved several hours later. All the iatrogenic pseudo aneurysms were treated successfully with an ultrasound-guided percutaneous thrombin injection. There was a high rate of hypersensitivity to the bovine thrombin, which precaution should be taken to prevent more serious side effects

    An intrahepatic artery pseudoaneurysm (IHAA) is a very rare but potentially lethal complication occurring after liver transplantation. This report presents a case of an IHAA associated with a metallic biliary stent after liver transplantation. A 40-year-old male underwent living donor liver transplantation (LDLT) using a left lobe graft. The bile duct reconstruction was performed with Roux-en-Y hepaticojejunostomy. He developed obstructive jaundice 5 years after LDLT, and had biliary stricture of the anastomosis area, therefore, the two metallic biliary stents were finally positioned at the stricture of the biliary tract. He suddenly developed hematemesis 8 years after LDLT, and computerized tomography scan showed an IHAA. Although seven interlocking detachable coils were placed at the neck of the aneurysm, hematemesis recurred 3 days after the initial embolization. Therefore, retransplantation was successfully performed 25 days after the embolization of IHAA using a right lobe graft from his son. In conclusion, metal stent insertion can lead to the fatal complication of HAA. The placement of a metallic stent could have been avoided in this case. Percutaneous metallic stent insertion for biliary stenosis after liver transplantation should therefore only be performed in carefully selected patients. PMID:22914885

  7. Pseudo-aneurysm of the anterior tibial artery, a rare cause of ankle swelling following a sports injury

    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.

    Full Text Available A artroscopia do joelho é considerado um procedimento cirúrgico muito seguro, com um número relativamente pequeno de complicações. Relatamos o caso de dois pacientes do sexo masculino que foram submetidos à artroscopia de joelho (para meniscectomia parcial e reconstrução do ligamento cruzado anterior com parafuso transverso femoral e interferência tibial que desenvolveram um pseudoaneurisma de artéria genicular superior lateral após o procedimento. A ultrassonografia com Doppler realizou o diagnóstico e os pacientes foram tratados cirurgicamente com ligadura arterial. Um paciente apresentou extenso hematoma na coxa e foi necessária reposição volêmica. Estes casos exemplificam uma complicação vascular rara, nem sempre benigna, em uma cirurgia minimamente invasiva do joelho.Arthroscopy of the knee is a very safe surgical procedure, with relatively few complications. Here we present the cases of two patients submitted to arthroscopic surgery for partial meniscectomy and reconstruction of the anterior cruciate ligament with femoral transverse screw and tibial interference screw that developed a superior lateral genicular artery pseudoaneurysm. Doppler ultrasonography was performed for diagnostic purposes and the patients were treated by direct arterial suture. One patient developed a large haematoma requiring volemic replacement. These cases illustrate a rare, and not always benign vascular complication, in a minimally invasive arthroscopic surgery.

    we report a case of a 74-year-old woman with a 16-year history of a double bilo-enteric anastomosis due to resected hilar cholangiocarcinoma [Type Ⅲb Klatskin tumor]. The patient presented with cholangitis secondary to benign anastomotic stenosis which resulted in a large intrahepatic biloma. In order to restore the patency of the anastomosis and overcome cholangitis, several attempts took place,including endobiliary stenting, balloon-assisted biloplasty and transhepatic billiary drainage. Anastomotic patencywas achieved, complicated, however, by persistent upper gastro-intestinal bleeding, presented as hemobilia. A biloma-induced pseudoaneurysm of the left hepatic artery was diagnosed. This had ruptured into the biliary tract,and presented the actual cause of the hemobilia. Selective embolism of the pseudoaneurysm resulted in control of the hemorrhage, and was successfully combined with transhepatic dilatation of the anastomosis and percutaneous drainage of the biloma. The patient was ultimately cured and seems to be in excellent condition, 5 mo after treatment.

    Swelling around the knees can be due to both neoplastic as well as non neoplastic aetiology. One of the rare cause for the same is pseudoaneurysm. Pseudoaneurysms can mimic a bone tumor or a soft tissue sarcoma. Pseudoanuerysms result because of the gradual growth occurring due to constant arterial pressure and development of a reactive fibrous capsule. Inappropriate diagnosis and management of these lesions may result in major morbidity and rarely mortality. We present two cases of pseudoaneurysms around the knees which were misdiagnosed as osteogenic sarcomas. These cases also stress on the importance of multidisciplinary care, in preventing avoidable morbidity, mortality and providing safe and optimal care to the patients. PMID:27437336

    Full Text Available Background: A plan for management of infected arterial pseudoaneurysm has evolved from our experience with forty two cases of such aneurysms treated between 1378 and 1382. Methods: Clinical data of 42 patients with femoral pseudoaneurysm resulting from addictive drug injection who presented in emergency department of Sina Hospital between 1378 and 1383 were retrospectively reviewed. Results: All patients were men with the mean age of 36.9 years. Twenty eight patients were referred from other medical centers. The mean time of delay in presentation was 17.3 days. The mean duration of drug injection was 14 months. Primary repair and emergent vascular bypass were performed in 3(7.1% and 2(4.8% patients, respectively. 5(11.9% patients undergone delayed revascularization. Thirty two (76.2% patients returned to their normal lifestyle without any vascular bypass. One patient required amputation and one patient died due to sepsis and acute renal insufficiency. Conclusion: Management of infected femoral pseudoaneurysms is simple ligation of the external iliac or femoral artery. When Doppler is not available “Operation Room and postoperative Direct Observation” is recommended in such patients to avoid unnecessary revascularization surgery.

    Full Text Available Context Pseudoaneurysms associated with pancreatitis are rare, and bleeding pseudoaneurysms are associated with a high mortality. Objective The aim of this study was to report the outcomes of endovascular and percutaneous therapy in the management of pseudoaneurysms secondary to pancreatitis. Patients Patients who underwent angiography for pseudoaneurysms associated with pancreatitis from 2005 to 2011 were identified from the angiography database. Main outcome measures Patient demographics, clinical presentation, radiological findings, treatment, and outcomes were retrospectively reviewed. Results Nineteen pseudoaneurysms associated with pancreatitis in 13 patients were identified. The diagnosis of a pseudoaneurysm was made by computerised tomography angiography in seven patients, followed by portal venous phase contrast enhanced CT (n=4, duplex ultrasound (n=1 and angiography (n=1. At angiography, coil embolisation was attempted in 11 patients with an initial success rate of 82% (n=9. One patient underwent successful embolisation with percutaneous thrombin injection. The recurrence rate following initial successful embolisation was 11% (n=1. There were no episodes of re-bleeding following embolisation but re-bleeding following thrombin injection was observed in one case. The morbidity and mortality rate in the 12 patients that were successfully treated was 25% (n=3 and 8% (n=1, respectively. All 12 patients that were successfully treated demonstrated radiological resolution of their pseudoaneurysms, with a median follow-up of 20 months. Conclusion Endovascular embolisation is a suitable first-line management strategy associated with low recurrence rates. The role of percutaneous thrombin injection is yet to be defined

    Objective To discuss the early diagnosis and treatment of cardiac penetrating injuries and pseudoaneurysm. Methods 18 cases of cardiac penetrating injuries, in which 2 cases were complicated with pseudoaneurysm, were diagnosed by emergency operation and color Doppler echocardiography between May 1973 and Dec. 2001 in our hospital. The basis for emergency operation is the injured path locating in cardiac dangerous zone, severe shock or pericardial tamponade. ResultsAmong 18 cases of this study, 17 cases underwent emergency operation. During the operation, 11 cases were found injured in right ventricle, 2 cases were found injured in right atrium, 1 case was found injured in pulmonary artery,4 cases were found injured in left ventricle, 2 cases were found complicated with pseudoaneurysm. 17cases underwent cardiac repair including 1 case of rupture of aneurysm. 1 case underwent elective aneurysm resection. In whole group, 15 cases survived(83.33% ), 3 cases died( 16.67%). The cause of death is mainly hemorrhagic shock. Conclusion Highly suspicious cardiac penetrating injuries or hemopericaridium should undergo direct operative exploration. Pseudoaneurysm should be resected early,which can prevent severe complications.

    The first reported application of uterine artery embolization, in 1979, was to treat life-threatening hemorrhage after a failed hysterectomy. Since then, uterine artery embolization has been used very successfully to control acute or delayed post-partum hemorrhage, post-surgical hemorrhage and hemorrhage from ectopic pregnancy, to treat uterine arteriovenous malformations and as prophylaxis before high-risk surgery, such as cesarean delivery in women with placenta previa. In contrast to these proven but underutilized applications, uterine embolization for fibroids has, in a short time, achieved significant notice in the lay press and is being widely offered. Ravina and colleagues, first reported uterine fibroid shrinkage after embolization for the treatment of acute bleeding. Since then, his group has performed over 100 procedures with up to a 6-year follow-up. The cumulative clinical success rate for the treatment of abnormal uterine bleeding due to fibroids is reported to be approximately 85% and for treatment of pain or pressure symptoms, about 75%. Six-month follow-up sonography reveals an average reduction of fibroid size of approximately 40%. However, to date, no studies have compared patients who undergo embolization with a nontreatment cohort or with surgical intervention. (author)

  6. CT angiography diagnosis on the rupture of traumatic pseudoaneurysms of the cavernous of the internal carotid artery into the sphenoid sinus

    International Nuclear Information System (INIS)

    Objective: To investigate diagnostic value of CTA for traumatic pseudoaneurysms (TPA) in the cavernous segment of the internal carotid artery (ICA) when they rupture into the sphenoid sinus. Methods: CTA of 7 patients with TPA in the cavernous segments of ICA verified by DSA were retrospectively analyzed. All the patients were performed CTA scanning. The post-processing techniques included VR, MIP, MPR, and CPR. Results: All the CTA images of 7 patients showed irregular mass in the sphenoid sinus with obviously enhancement in the same phase to ICA, which communicating with ICA in wide base. The peripheral area of the mass showed no enhancement. The size varied from 3 mm × 2 mm × 1 mm to 33 mm × 30 mm × 27 mm. The adjacent lateral wall of sphenoid sinus showed fractures in all cases. TPA located at anterior-knee segments of cavernous ICA in 6 cases, and cavernous free segment in 1 case. All the disruptions were found at medial or anterior medial wall of ICA. Conclusions: Cranial CTA is the effective non-invasive method for diagnosing TPA in the cavernous segment of ICA when they rupture into sphenoid sinus. Combined using of VR, MIP, MPR, and CPR can delineate the location and size of the sphenoid wall fracture and the ICA rupture, which help to clarify the anatomical relationship between them.

    2016-01-01

    Aneurysms and pseudoaneurysms of the internal mammary artery (IMA) are rare and the etiology uncertain although iatrogenic causes have been described. A 64-year-old woman suffered hematoma and bleeding from a pseudoaneurysm probably originating from a branch of the right IMA 16 years after breast...... implant surgery. After clinical assessment, the patient underwent surgery with resection of the aneurysm and ligation of the arterial branch. No early postoperative complications were reported. Pseudoaneurysms in small vessels such as the IMA or its branches are not well described in the literature...

    Severe stenosis/occlusion of the proximal celiac trunk due to median arcuate ligament compression (MALC), arteriosclerosis, pancreatitis, tumor invasion, and celiac axis agenesis has been reported. However, clinically significant ischemic bowel disease attributable to celiac axis stenosis/occlusion appears to be rare because the superior mesenteric artery (SMA) provides for rich collateral circulation. In patients with celiac axis stenosis/occlusion, the most important and frequently encountered collateral vessels from the SMA are the pancreaticoduodenal arcades. Patients with celiac artery stenosis/occlusion are treated by interventional radiology (IR) via dilation of the pancreaticoduodenal arcade. In patients with dilation of the pancreaticoduodenal arcade on SMA angiograms, IR through this artery may be successful. Here we provide several tips on surmounting these difficulties in IR including transcatheter arterial chemoembolization for hepatocellular carcinoma, an implantable port system for hepatic arterial infusion chemotherapy to treat metastatic liver tumors, coil embolization of pancreaticoduodenal artery aneurysms, and arterial stimulation test with venous sampling for insulinomas.

    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

    To evaluate the efficacy of angiography in the diagnosis and treatment of pseudoaneurysm manifesting arterial hemorrhage as a significant complication following pancreatoduodenectomy. For 51 months, of a total of 298 patients who had undergone pancreatoduodenectomy, 19 patients (6.4%) developed clinically significant hemorrhage and nine patients proved to have a pseudoaneurysm of angiography. These nine patients (3.0%) were managed by transcatheter arterial embolization. We analyzed clinical feature, angiography findings and hemostatic effect of embolization retrospectively. In nine patients (3.0%), pseudoaneurysm was diagnosed on angiography (common hepatic artery in four, gastroduodenal artery in three, proper hepatic artery in one, and left gastroepoploic artery in on patient). The size ranged from 0.3 cm to 6.5 cm (mean 1.9 cm). And extravasation was noted in five patients (55.6%). The remained ten patients showed no evidence of bleeding on angiography. Those who manifested as early bleeding (within two weeks) or delayed bleeding ( later than two weeks) were five and four patients respectively. Before the onset of major bleeding, among the nine pseudoaneurysm patients, seven patients (77.8%) had experienced percutaneous drainage due to intra-abdominal fluid collection with or without abscess resulting from anastomotic leak, and all nine patients had preliminary minor bleeding. The angiogram demonstrated an exact site of bleeding as a pseucoaneurysm followed by transcatheter arterial embolization (microcoil in eight patients, gelfoam in one) and achieved complete hemostasis yielding a success rate of 100%. Overall, no patients experienced complications related directly to the transcatheter arterial embolization technique. During the follow-up period (72-1, 336days, mean 640), no recurrence of bleeding was note. Although pseudoaneurysm is a rare complication, it is important as a cause of hemorrhage after pancreatoduodenectomy. Angiography followed by

    Objective: To evaluate the inducing chemotherapy through superselective arterial approch for patients with advanced tongue squamous cancinoma. Methods: Two patients with advanced tongue cancinoma of III stage were treated with lingual arterial superselective chemoembolization via femoral arterial approach with mixture of CDDP 150-200 mg, 5-FU 1.5-2.0 g, PYM 50-80 mg together with stripes of gelfoam sponge. Effects of the chemotherapy were evaluated and the tumors were undergone surgery 14 d after the chemoembolization. Results: The tumor masses became smaller associated with necrosis, disaggregation and liquefaction with a week after the therapy accompanied by slight systemic side effects, and signs of recurrence or metastasis was not found after follow-up of 18 months. Conclusion: Pre-operative superselective arterial chemoembolization would minimize complications, promote the effectiveness and be a good therapy for advanced tongue cancinoma. (authors)

    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.

    Delayed rupture of post-traumatic pseudoaneurysms of the visceral arteries, especially the pancreaticoduodenal artery, is uncommon. Here, we describe a 55-year-old man hemorrhaging from a pseudoaneurysm of the inferior pancreaticoduodenal artery (IPDA). Computed tomography of the abdomen showed active bleeding in the IPDA and large amounts of hemoperitoneum and hemoretroperitoneum. Selective mesenteric angiography showed that the pseudoaneurysm arose from the IPDA, and treatment by angioembolization failed because the involved artery was too tortuous to fit with a catheter. Damage control surgery with surgical ligation and pad packing was successfully performed. The patient had an uncomplicated postoperative course and was discharged 19 days after the operation. To our knowledge, this is the first report of ruptured pseudoaneurysm of an IPDA after blunt abdominal trauma from Korea. PMID:22880189

    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. More evidence is required for the application of this treatment.

    Aneurysms and pseudoaneurysms of the internal mammary artery (IMA) are rare and the etiology uncertain although iatrogenic causes have been described. A 64-year-old woman suffered hematoma and bleeding from a pseudoaneurysm probably originating from a branch of the right IMA 16 years after breast implant surgery. After clinical assessment, the patient underwent surgery with resection of the aneurysm and ligation of the arterial branch. No early postoperative complications were reported. Pseudoaneurysms in small vessels such as the IMA or its branches are not well described in the literature. Proper diagnosis with imaging is of importance in order to determine treatment as each case is unique. Some cases can be managed conservatively. PMID:27470014

    Full Text Available O uso de cateteres venosos centrais em pacientes hemofílicos é muito freqüente, devido às próprias características terapêuticas da doença. As complicações desses procedimentos, tais como pseudo-aneurisma, geralmente são mais graves nesses pacientes. A correção cirúrgica do pseudo-aneurisma que acomete a artéria subclávia constitui um dos maiores desafios da cirurgia vascular. Em pacientes hemofílicos, à dificuldade habitual de exposição cirúrgica somam-se os problemas de alteração no processo normal de coagulação. Como alternativa ao tratamento cirúrgico convencional, a utilização de técnicas endovasculares constitui uma solução segura e com bons resultados.The placement of central venous catheters in hemophiliac patients is very frequent, due to the specific treatment characteristics of the disease. The complications of these procedures, such as pseudoaneurysm, are generally worse in such patients. Surgical treatment of subclavian artery pseudoaneurysm is known to be one of the greatest surgical challenges in vascular surgery. In hemophiliac patients, the alterations in the normal cascade of coagulation are added to the difficult surgical exposure. As an alternative to the usual surgical treatment, the use of endovascular techniques is a safe method and has good outcomes.

  12. Pushable springcoil embolization of pseudoaneurysms caused by gluteal stab injuries

    International Nuclear Information System (INIS)

    Purpose: To retrospectively review the outcomes of 21 patients with stab wounds to the gluteal region who underwent embolization for pseudoaneurysms causing active bleeding. Materials and methods: Between 1997 and 2007, 3 superior gluteal artery, 2 inferior gluteal artery and 16 deep femoral artery muscular branch pseudoaneurysms detected by digital subtraction angiography were selectively catheterized with diagnostic catheters with hydrophilic coating and embolized with pushable springcoils. 17 of the 21 pseudoaneurysms were located in a distal end of an artery where outflow vessels could not be depicted. The other 4 lesions were side wall injuries which required the placement of coils distal and proximal to the injury site. Results: Embolization was successful in controlling the bleeding in all of the patients. 16 patients required 1 or 2 coils, 4 patients required 3 coils and 1 patient required 5 coils. 2 patients had femoral puncture site hematomas which resolved spontaneously. 2 patients required surgical evacuation of large gluteal hematomas following the embolization because of symptoms second to mass effect. There were no procedure related major complications or mortality. Conclusions: Our experience demonstrates that pushable coil embolization is a relatively simple, effective and economic method for the embolization of pseudoaneurysms caused by penetrating gluteal injuries. Experimenting with other embolization materials does not seem to be justified.

    Full Text Available Objective: To determine the risk factors, clinical characteristics, surgical management and outcome of pseudoaneurysm secondary to iatrogenic or traumatic vascular injury. Methods: 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. Results: 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. Conclusion: 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

    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 disch...

  16. An Unusual Cause of a Pain in the Neck: Pseudoaneurysm from Tuberculous Lymphadenitis

    Directory of Open Access Journals (Sweden)

    2012-01-01

    Full Text Available A pseudoaneurysm is a haematoma which is surrounded by connective tissue and communicates with the lumen of a ruptured blood vessel. It has no true defined capsule. We describe a case of tuberculous pseudoaneurysm. This is a rare complication of tuberculosis. The clinical presentation of these lesions is highly variable. Definitive diagnosis should consist of contrast-enhanced CT and arteriography. Treatment should include repair of the arterial wall by surgery, endovascular stent-graft insertion, or embolization followed by a full course of antituberculous chemotherapy. Our case is highly unusual in that the pseudoaneurysm arose from the subclavian vasculature in a patient with extrapulmonary tuberculosis only.

    Full Text Available Anastomotic pseudoaneurysms are common entities following vascular bypass procedures and, if left untreated, serious complications such as thromboses, infection, and rupture can frequently occur. Therefore, attempts to employ various methods of repair have been utilized in treating anastomotic pseudoaneurysms to maximize operational success and future risk reduction. Herein, the authors report two cases of anastomotic pseudoaneurysms which were repaired percutaneously utilizing a combination of strategies such as careful preoperational image planning, multiple commercially available devices, and secondary embolization techniques.

  18. Hemobilia into a metallic biliary stent due to pseudoaneurysm. A case report

    International Nuclear Information System (INIS)

    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)

    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.

    Pulmonary arterial hypertension (PAH) is rare, but patients who are diagnosed with this disease still suffer from a lack of satisfactory treatment strategies to prolong survival. While currently approved drugs for PAH have some benefits, these vasodilators only have limited efficacy for eliminating pulmonary vascular remodeling and reducing mortality. Thus, our laboratory has been exploring the use of aggressive drugs, which are capable of causing apoptotic cell death, to treat PAH. We have so far found that three classes of anti-tumor agents, including anthracyclines, taxanes, and proteasome inhibitors, are capable of reducing pulmonary vascular thickness in rats with PAH. These drugs kill cells in remodeled pulmonary vessels without affecting the normal, healthy pulmonary vasculature, revealing that proliferating vascular cells in PAH patients are more sensitive to drug-induced apoptosis compared to the differentiated phenotype that is physiologically important for smooth muscle contraction. Since many apoptosis-inducing drugs cause cardiotoxicity in cancer patients, and because PAH patients already have a weakened heart, we focus on finding biological mechanisms that may reverse pulmonary vascular remodeling without promoting cardiotoxicity. We found two agents, dexrazoxane and pifithrin-α, that selectively inhibit cardiac muscle apoptosis without affecting the drug-induced apoptosis of the proliferating pulmonary vascular cells. Thus, we propose that the addition of apoptosis-inducing drugs and cardioprotectants to PAH therapies may be effective in treating patients and preventing right heart failure.

    2008-01-01

    Full Text Available Aims: To investigate the characteristics and surgical treatment of traumatic intracranial pseudoaneurysms. Materials and Methods: Twelve patients with traumatic intracranial pseudoaneurysms were operated on in our hospital between 2000 and 2006. Their clinical characteristics, radiological features and surgical techniques were analyzed retrospectively. Four traumatic cavernous segment pseudoaneurysms underwent trapping of the internal carotid artery and others underwent "neck reinforcement and clipping" or "crevasse clipping". Results: Nine patients were excellent or good and two patients were poor when they discharged. One patient died of postoperative cerebral infarction. Nine patients underwent follow-up (three months to seven years and rebleeding was not seen in them. Conclusions: The surgical treatment of traumatic intracranial pseudoaneurysms is risky and difficult and individualized surgical option is necessary. Understanding the compensation of intracranial blood circulation, preoperative "Matas test" if it is necessary, perioperative hemodynamics testing and the application of revascularization techniques, will help reduce surgical risk and achieve a good surgical outcome.

    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.

    Full Text Available Background/Objective: Arterial blood gas (ABG analysis is useful in evaluation of the clinical condition of critically ill patients; however, arterial puncture or insertion of an arterial catheter may sometimes be difficult and cause many complications. Arterialized ear lobe blood samples have been described as adequate to gauge gas exchange in acute and chronically ill pediatric patients. Purpose: This study evaluates whether pH, partial pressure of oxygen (PO 2 , partial pressure of carbon dioxide (PCO 2 , base excess (BE, and bicarbonate (HCO 3 values of arterialized earlobe blood samples could accurately predict their arterial blood gas analogs for adult patients treated by mechanical ventilation in an intensive care unit (ICU. Setting: A prospective descriptive study Methods: Sixty-seven patients who were admitted to ICU and treated with mechanical ventilation were included in this study. Blood samples were drawn simultaneously from the radial artery and arterialized earlobe of each patient. Results: Regression equations and mean percentage-difference equations were derived to predict arterial pH, PCO 2 , PO 2 , BE, and HCO 3 -values from their earlobe analogs. pH, PCO 2 , BE, and HCO 3 all significantly correlated in ABG and earlobe values. In spite of a highly significant correlation, the limits of agreement between the two methods were wide for PO 2 . Regression equations for prediction of pH, PCO 2 , BE, and HCO3- values were: arterial pH (pHa = 1.81+ 0.76 x earlobe pH (pHe [r = 0.791, P < 0.001]; PaCO 2 = 1.224+ 1.058 x earlobePCO 2 (PeCO 2 [r = 0.956, P < 0.001]; arterial BE (BEa = 1.14+ 0.95 x earlobe BE (BEe [r= 0.894, P < 0.001], and arterial HCO 3 - (HCO 3 -a = 1.41+ earlobe HCO 3 (HCO 3 -e [r = 0.874, P < 0.001]. The predicted ABG values from the mean percentage-difference equations were derived as follows: pHa = pHe x 1.001; PaCO 2 = PeCO 2 x 0.33; BEa = BEe x 0.57; and HCO 3 -a = HCO 3 -e x 1.06.

    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.

    Full Text Available Objective To explore the safety and effectiveness of contrast-enhanced ultrasound (CEUS-guided percutaneous injection of prothrombin for the treatment of limb pseudoaneurysm (PSA. Methods Sixteen cases of lower limb pseudoaneurysms were treated with contrast-enhanced ultrasound (CEUS-guided percutaneous injection of prothrombin, and the size of the pseudoaneurysm, width and length of the pseudoaneurysm neck, times for compression, duration of each compression, and dose of prothrombin injection were recorded. Results In 16 pseudoaneurysm patients, there were 20 pseudoaneurysm sacs in total. One pseudoaneurysm sac was present in 13 patients, 2 sacs were present in 2, and there were 3 sacs in one patient. The mean maximum diameter of the sacs was 41.1±11.9mm. The mean width and length of these pseudoaneurysm necks were 1.9±0.5mm and 4.4±2.3mm respectively. During the process of treatment, the mean duration for compression was 6.0±2.0min, and the mean number of times of compression was 1.2±0.4. The mean dose of prothrombin injection was 411.5±118.8U. The cure rate with one-injection was 100% (16/16, and the recurrence rate was 0%. No complications was observed. Conclusions CEUS-guided percutaneous injection of prothrombin for the treatment of lower limb pseudoaneurysms is safe and effective. The size of the pseudoaneurysm sac and length of the pseudoaneurysm neck are important factors that may affect the result of the treatment. Timely recompression is an important step for increasing the cure rate. DOI: 10.11855/j.issn.0577-7402.2014.01.09

    We report a very rare case of a 47-year-old man who had coronary spasm that resulted in a silent myocardial infarction, a ruptured myocardial wall, and a nonruptured left ventricular pseudoaneurysm. The patient presented with a 6-month history of dyspnea on exertion, without evidence of fixed coronary artery stenosis. Coronary angiography showed severe coronary spasm of the left anterior descending and left circumflex arteries; the spasm was relieved promptly by nitroglycerin. Echocardiography and left ventricular angiography revealed the large left ventricular pseudoaneurysm posterolateral to the left ventricle. We performed surgical resection of the pseudoaneurysm and patch repair of the ruptured left ventricular wall, with excellent results. We present this case because of the highly unusual sequence of events. Early surgical intervention resulted in the patient's recovery.

    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. PMID:25349770

    Portal vein arterialization (PVA) has been applied as a salvage procedure in hepatopancreatobiliary surgeries, including transplantation and liver resection, with revascularization for malignancies. Here we describe the use PVA as a salvage procedure following accidental injury of the hepatic artery to the remnant liver occurred during left hepatic trisectionectomy for colorectal liver metastases (CRLM). A 60-year-old man with cancer of the sigmoid colon and initially unresectable CRLM received 11 cycles of hepatic arterial infusion chemotherapy with 5-fluorouracil (1500mg/week), after which CRLM was downstaged to resectable. One month after laparoscopic sigmoidectomy, a left trisectionectomy and wedge resection of segment 6 were performed. The posterior branch of the right hepatic artery, the only feeding artery to the remnant liver, was injured and totally dissected. Because microsurgical reconstruction of the artery was impossible, PVA was used; PVA is the sole known procedure available when hepatic artery reconstruction is impossible. The patient then suffered portal hypertension, and closure of arterio-portal anastomosis using an interventional technique with angiography was eventually performed on postoperative day 73. Therefore, it is considered that because PVA is associated with severe postoperative portal hypertension, closure of the arterio-portal shunt should be performed as soon as possible on diagnosing portal hypertension.

    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.)

    Full Text Available Background. Aneurysms of the extracranial vertebral artery are rare and can provide a diagnostic and therapeutic challenge. Methods. We reviewed the clinical history of a patient presenting with cervical radiculopathy, who harboured an extracranial vertebral artery aneurysm eroding the cervical spine. Results. CT Angiography and MR Angiography set the diagnosis, by revealing a left C5-C6 vertebral artery aneurysm with cervical root impingement. Bony reconstruction depicted enlargement of the C6 transverse foramen and a marked enlargement of the C6-C7 intravertebral foramen. The lesion was treated by intravascular proximal vertebral artery occlusion. Conclusions. Extracranial vertebral artery aneurysms require a high index of clinical suspicion. This is the first report of a vertebral artery pseudoaneurysm presenting with bony erosion, which supports a less minacious portrayal of vertebral artery aneurysms.

The usual pathogenesis of aneurysms in this location is either penetrating or blunt trauma with resultant pseudo- aneurysm formation. We report a patient with a presumed pseudo-aneurysm of the extra- cranial vertebral artery presenting with painful neck mass, without obvious history of trauma. Case description: A 59-year old man presented with painful left lateral neck mass from 3 month ago with a bruit over it on physical examination. Patient had a history of long term anticoagulant therapy because of chronic lower extremity DVT. Patient was referred to our DSA (Department for angiography. After color Doppler US, CT scan and MR-angiography were performed and a giant aneurysm in left vertebral artery was detected. The lesion was successfully treated by an endovascular technique of balloon occlusion of the verte-bral artery.

  5. Endovascular embolization through pulmonary artery access for refractory massive hemoptysis

    International Nuclear Information System (INIS)

    Objective: To determine the effectiveness of endovascular embolization through pulmonary artery access in patients with refractory massive hemoptysis in whom systemic artery (SA) embolization is ineffective or contraindicated. Methods: A total of 102 patients were treated with SA embolization for hemoptysis. Of the 102 patients,6 patients had severe persistent hemoptysis despite complete SA embolization and 1 patient had severe hemoptysis following complete bronchial artery embolization and other SA embolization was contraindicated. The underlying diseases were chronic cavitary pulmonary tuberculosis (n=3), chronic cavitary pulmonary tuberculosis complicated with aspergilloma (n=1), tuberculous bronchiectasis (n=1), severe necrotizing pneumonia (n=1) and bronchiectasis complicated with pneumatocele (n=1). The findings of SA angiography, main pulmonary angiography and selective pulmonary angiography were analyzed. Endovascular embolization was performed in patients with the detectable pathology in PA and the clinical results were observed. Results: The findings of SA angiography showed bronchopulmonary shunting in all cases, and pseudoaneurysm of PA in 2 cases and hypertrophy of peripheral PA in 2 cases. The main PA angiography demonstrated pseudoaneurysm of PA in 1 case and hypoperfusion of the diseased PA in other case. The selective PA angiography demonstrated pseudoaneurysm of PA in 4 cases (1 case with extravasation of contrast medium) and hypertrophy of peripheral PA in 2 cases. Coil embolization of the pathologic PA were successfully performed and bleeding ceased in all patients. During follow-up, 1 patient had episodic bloody sputum after embolization, and 2 died day 6 and 15 of severe infection and respiratory failure and the remaining patients were all stable, Conclusions: In patients with refractory massive hemoptysis after systemic embolization, the possibility of PA pathology, especially pseudoaneurysm of PA should be considered.

    The objective of this study was to evaluate the efficacy and safety of intra-arterial thrombolysis in treating acute cerebral infarction and further discuss the indications of acute cerebral infarction treatment, in order to enhance the therapeutic effects of arterial thrombolysis. The data of 164 patients with acute cerebral infarction who accepted intra-arterial thrombolysis treatment by using rt-PA or reteplase between 2009 and 2014 at the Department of Neurology of our hospital, were collected, including patients' medical history, characteristics of the onset procedure, intervals between onset and intra-arterial thrombolysis, bleeding or death, and the changing process of patient's main neurologic function after the treatment. The neurological functions including muscle strength, speech, and level of consciousness were chosen for evaluation. Through a review of cerebral angiography, we collected the digital subtraction angiography (DSA) morphological changes of blood vessels before and after arterial thrombolysis to evaluate whether those blood vessels had been reperfused. Thereafter, we analyzed and statistically processed above-mentioned data. The mean time of arterial thrombolysis was 5.7 h. DSA results were as follows: 22 patients had complete internal carotid artery (ICA) occlusion; 49 patients middle cerebral artery's (MCA's) Ml or M2 segment occlusion; 6 patients anterior cerebral artery (ACA) occlusion; 58 patients reperfusion after thrombolysis, and the recanalization rate was 76 %. Based on vertebral-basilar artery (VBA) system, 18 patients had complete occlusion, 11 patients had reperfusion after thrombolysis, and the recanalization rate was 61 %. A total of 63 patients had severe stenosis, and they had significantly improved after thrombolysis. The clinical symptoms of patients were improved: 79 out of 164 patients with paralysis had partially recovered their limb muscle strength after operation, while 33 patients had completely recovered, and

  8. The application of interventional radiological procedures in treating hepatic artery complications occurred after liver transplantation

    International Nuclear Information System (INIS)

    Objective: To evaluate the interventional radiological procedures in treating hepatic artery complications occurred after liver transplantation. Methods: Thirteen patients with hepatic artery complications occurred after liver transplantation received interventional treatment. The interventional procedures included (1) percutaneous transarterial angioplasty (PTA) or endovascular stenting (ES) for 6 patients with hepatic artery stenosis (HAS) and for 3 patients with hepatic artery occlusion; (2) catheter-directed thrombolysis for 3 patients with hepatic artery thrombosis (HAT) and (3) coil embolization for one patient with gastroduodenal steal syndrome (GSS). Immediate, short-term and long-term effects were observed and evaluated. Results: The general immediate effective rate was 84.62% (11/13). The effective rate was 100% for HAS (6/6), HAT (3/3) and GSS (1/1). However, the effective rate for hepatic artery occlusion was only 33.3% (1/3). Color Doppler ultrasonography showed that the hepatic arterial flow remained fluent. Three days after the treatment statistically significant decrease in ALT (t=2.68, P<0.050) and T-BIL (t=2.94, P<0.05) was observed. No procedure-related complications or death occurred during the follow-up period of 2-34 months. Conclusion: As a safe, effective and minimally-invasive technique, interventional management can be regarded as the treatment of first choice for hepatic artery complications occurred after liver transplantation.

    Radial access has been increasingly utilized for coronary intervention due to higher safety profile in comparison to femoral access site with lower bleeding rate. Radial artery occlusion is not uncommon with radial access site. This usually does not lead to any harm due to ulnar artery collaterals that are sufficient to prevent hand ischemia and is usually left alone. However, in the case of significant hand ischemia, treatment is often necessary. We are reporting an interesting case of symptomatic radial artery thrombosis leading to arm ischemia that was successfully treated percutaneously using femoral access. Using femoral access for radial artery intervention has not been reported previously. This case is followed by review of the literature.

  11. Embolization of Isolated Lumbar Artery Injuries in Trauma Patients

    International Nuclear Information System (INIS)

    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.)

    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.

    Aneurysms and pseudoaneurysms of the superior mesenteric artery are potentially lethal and should be treated as urgently as possible.In a 52-year-old man with occasional epigastric pain,we accidentally discovered a superior mesenteric artery aneurysm that was ruptured with spontaneous tamponade in the uncinate process and in the head of the pancreas.The ruptured aneurysm had a heterogeneous appearance due to its thrombotic and hemorrhagic content,and it simulated a voluminous mass in the head and uncinate p...

  17. The application of uterine artery chemoembolization in treating cesarean section scar pregnancy

    International Nuclear Information System (INIS)

    Objective: To discuss the feasibility and safety of uterine artery chemoembolization in treating cesarean section scar pregnancy. Methods: During the period of Jun. 2005-Jun. 2010, uterine artery chemoembolization was performed in 130 patients with cesarean section scar pregnancy in authors' hospital. Via bilateral uterine arteries 100-150 mg MTX and 80 000 u Gentamycin were infused separately, which was followed by the embolization of bilateral uterine arteries with Gelfoam. Of the total 130 patients,coexisted leiomyoma was found in 23 and embolization therapy with PVA microspheres was employed. Curettage of uterus was carried out within 24-72 hours after the procedure. Results: The success rate of bilateral uterine artery chemoembolization was 100%. The blood loss during curettage procedure was 12-110 ml (mean 28.5 ml). No serious complications occurred. Conclusion: The uterine artery chemoembolization is an effective and safe treatment for cesarean section scar pregnancy. This technique can greatly avoid unnecessary uterectomy and, thus, preserve the fertility of the female patients. (authors)

    Objective: To assess the clinical value of bilateral uterine artery chemotherapy embolization (UACE) for cervical ectopic pregnancy analyzed. Methods: Clinical records of 40 patients with cervical ectopic pregnancy treated using UACE were retrospectively analyzed. Results: 8 patients with severe active vaginal bleeding after curettage were treated urgently with UACE. The remaining 32 patients were treated with UACE combined with sequential ultrasound-guided curettage. Active vaginal bleeding was stopped after UACE. There was no recurrent hemorrhage with the sequential ultrasound-guided curettage procedure. The β-HCG levels of all patients were normalized after 1 month. Conclusion: Bilateral uterine artery chemotherapy embolization is valuable as emergency treatment for patients with severe vaginal bleeding from cervical ectopic pregnancy. UACE combined with sequential ultrasound-guided curettage may be more effective. (authors)

    2010-01-01

    Full Text Available Cardiovascular abnormalities are well-known manifestations of tertiary syphilis infections which although not frequent, are still causes of morbidity and mortality. A less common manifestation of syphilitic aortitis is coronary artery ostial narrowing related to aortic wall thickening. We report a case of a 46-year-old male admitted due to acute anterior ST elevation myocardial infarction submitted to primary percutaneous coronary intervention successfully. Coronary angiography showed a suboccluded ostial lesion of left main coronary artery. VDRL was titrated to 1/512. The patient was discharged with treatment including benzathine penicillin. Previous case reports of acute myocardial infarction in association with syphilitic coronary artery ostial stenosis have been reported, but the fact that the patient was treated by percutaneous coronary intervention is unique in this case.

    A traumatic pseudoaneurysm of the abdominal aorta is a rare entity, occurring as the result of a missed aortic lesion at the time of the initial injury. Therefore, clinical suspicion and careful abdominal exploration at first laparotomy is mandatory to prevent aortic pseudoaneurysm formation and its risk of delayed rupture. We present a case of successful surgical treatment of a suprarenal aortic false aneurysm, presenting 4 weeks after a life-threatening gunshot wound in a 13-year-old child. PMID:10499389

    Full Text Available Context Delayed arterial hemorrhage after pancreatoduodenectomy is defined as bleeding 5 or more days postoperatively. Objective We present the management of delayed hemorrhage after PD, due to gastro-duodenal arterial stump aneurysm. Case report A sixty-nineyear- old man suffering from pancreatic head carcinoma underwent pancreatoduodenectomy. On the 12th postoperative day he developed melena. Endoscopic evaluation revealed occult bleeding coming from the afferent limb of the gastro-jejunal anastomosis. The patient was treated conservatively. On the 15th postoperative day the patient presented a new episode of melena and hematemesis. Upper abdominal series control by computer tomography, selective angiography of the celiac trunk and superior mesenteric artery set the diagnosis of a pseudoaneurysm of the gastro-duodenal arterial stump. The patient was managed by trans-catheter arterial embolization and complete hemostasis was achieved. Conclusion Delayed intraluminal hemorrhage after pancreatoduodenectomy may be caused after pseudoaneurysm due to some visceral arterial stem erosion. Initial management, both diagnostic and therapeutic, should be the angiographic control and trans-catheter embolization of the bleeding vessel. In case of hemodynamic instability or when angiographic embolism is unsuccessful reoperation is the proper treatment.

    A 20-year-old man underwent a Tc-99m HMPAO labeled leukocyte scan for the evaluation of an infection at the stump of an AK amputation, which was conducted due to an open communicated fracture of the left lower leg. Blood-flow and blood-pool images demonstrated a pseudoaneurysm with a focus of intense activity medial to the stump, and centered within a large photopenic defect by surrounding hematoma. Delayed image obtained at 3 hours post-injection showed persistent intense and slight increased activity. Contrast angiography confirmed the presence of a pseudoaneurysm arising from a branch of the left superficial femoral artery.

    We report a case of acute stent recoil occurring after the stenting of an ostial left main coronary artery lesion. The marked recoil after high-pressure balloon inflation confirmed that the radial force of the first stent was unable to ensure vessel patency. The addition of a second stent provided the necessary support to achieve a good final result. This case illustrates a possible complication of aorto-ostial angioplasty that could be treated with double stenting. PMID:12499528

  4. Clinical application of uterine artery embolization in treating uterine scar pregnancy

    International Nuclear Information System (INIS)

    Objective: To evaluate uterine artery embolization in treating uterine scar pregnancy. Methods: During the period from November 2007 to February 2010, 11 patients with uterine scar pregnancy were encountered in authors' hospital. All the patients had a history of lower uterine segment cesarean section. Four patients had to receive an emergency uterine artery embolization due to acute massive vaginal bleeding. The other 7 patients received intravenous chemotherapy with MTX (0.4 mg/kg/day, every 5 days as a treatment course). Emergency uterine artery embolization had to be carried out in three patients as they developed acute massive vaginal bleeding (blood loss ≥ 100 ml/hour) during the course of chemotherapy, while subsequent uterine artery embolization was performed in the remaining 4 patients after they had completed two courses of treatment when their blood HCG showed no significant decrease. The clinical results were analyzed. Results: Remarkable decrease in serum HCG was seen in all 11 patients after interventional management. The vaginal bleeding in 7 patients was significantly reduced within half an hour after uterine artery embolization. The uterus together with intact fertility was successfully preserved in all 11 patients. Conclusion: For the treatment of uterine scar pregnancy complicated by massive vaginal bleeding (blood loss ≥ 500 ml/24 h) and/or abnormal elevation of serum HCG (blood β-HCG ≥ 20000 IU/L), ectopic pregnancy with the mass diameter ≥ 5 cm, uterine artery embolization treatment is very safe and effective. This technique can well preserve female patient's uterus and fertility ability. It is of value to employ this treatment in clinical practice. (authors)

    Objective: To study the expressions of Fas, FasL, Bax,Bcl-2 and P53 in thyroid tissue and to analyzis (Semi-quantitative analysis)the relation between change of apoptosis in thyroid tissues and clinical therapeutic effect after thyroid arterial embolization in treating hyperthyroidism caused by Graves' disease with observation of apoptosis for 3 years. Methods: 15 patients undergone core needle biopsy of the thyroid gland were divided into three groups according to the amount of time elapsed after thyroid arterial embolization: A group, before thyroid arterial embolization, B group, 1 year group (including 7-day subgroup, 3-month subgroup, 6-month subgroup) and C group, 1 year subgroup and mom than 1 year subgroup after arterial embolization. Results: (1) After embolisation, 15 patients' symptoms and signs of hyperthyroidism disappeared or improved greatly with 9 long term released and 6 improved with small amount of ATD maintenance. (2) The positive staining of Fas and FasL located in endochylema and cell-membrane of thyroid tissue from patients treated with transcathter arterial embolization were higher than those not treated with transcathter arterial embolization (P0.05). (4) The positive cell and the staining of P53 in thyroid tissue had significant difference before and after thyroid arterial embolization (P<0.05). Conclusions: The extra-expression and the increased expression of Fas, FasL, Bax, P53 in thyroid tissue of patient with GD treated by thyroid arterial embolization are correlated with the effects of interventional therapy.

    作者三十年间共收治了6例颈部感染性假性动脉瘤.本文就该症的病理临床表现进行了总结.提出了治疗意见.%Caused by pyogenic infection of deep cervical lymph nodes, the pseudoaneurysms of the carotid artery and its branches in the neck are rare. Six cases were handled in the past 30 years. They were three cases of aneurysm of lignual artery, one of external carotid artery, one of internal carotid artery and one of an unidentified branch of the external carotid artery. Outstanding symptoms and signs are as follows: infection in the neck; hematemesis with or without choking resulting from the ruptured aneurysm into the throat; hoarseness, dysphagia, and Horner's syndrome caused by pres sure on vagus, hypoglossal, glossopharyngeal or sympathetic nerves. Pseudoaneurysm as a complication of local suppuration usually lacks of typical findings of an aneurysm, such as expansile pulsation and systolic bruit. It might be misdiagnosed as an abscess. And if incorrectly treated with incision and drainage, blood would gush out terribly from the wound. It should be emphasized that a experimental puncture is preferable. During operation, a temporary occlusion on the proximal part of the feeding vessels must be done before the exploration and ligation of the perforated artery. Thus treated, all the six cases survired without permanent neurologic sequelae.

    A 12-year-old boy presented with severe arterial hypertension due to a severe subsegmental renal artery stenosis. Treatment consisted of selective embolization of the stenosed polar artery, which resulted in near normalization of the arterial pressures. Renal artery stenosis should always be considered, even in young adolescents, as a cause for arterial hypertension. Only selective angiography was able to demonstrate the subsegmental artery stenosis in this patient. (orig.)

    Development of direct-acting antiviral agents against hepatitis C virus (HCV) has changed the management of chronic HCV infection. We report three cases of newly diagnosed or exacerbated pulmonary arterial hypertension (PAH) in patients treated with sofosbuvir. All patients had PAH-associated comorbidities (HIV coinfection in two, portal hypertension in one) and one was already being treated for PAH. At admission, all patients presented with syncope, World Health Organization functional class IV, right-sided heart failure, and extremely severe hemodynamic parameters. After specific PAH therapy, the clinical and hemodynamic properties for all patients were improved. Severity and acuteness of PAH, as well as chronology, could suggest a causal link between HCV treatment and PAH onset. We hypothesize that suppression of HCV replication promotes a decrease in vasodilatory inflammatory mediators leading to worsening of underlying PAH. The current report suggests that sofosbuvir-based therapy may be associated with severe PAH.

    We report a case of acute ischemic stroke involving both the anterior and posterior circulation associated with a persistent primitive trigeminal artery (PPTA), treated by endovascular revascularization for acute basilar artery (BA) occlusion via the PPTA. An otherwise healthy 67-year-old man experienced sudden loss of consciousness and quadriplegia. Magnetic resonance imaging showed an extensive acute infarction in the right cerebral hemisphere, and magnetic resonance angiography showed occlusion of the right middle cerebral artery (MCA) and BA. Because the volume of infarction in the territory of the right MCA was extensive, we judged the use of intravenous tissue plasminogen activator to be contraindicated. Cerebral angiography revealed hypoplasia of both vertebral arteries and the presence of a PPTA from the right internal carotid artery. A microcatheter was introduced into the BA via the PPTA and revascularization was successfully performed using a Merci Retriever with adjuvant low-dose intraarterial urokinase. After treatment, his consciousness level and right motor weakness improved. Although persistent carotid-vertebrobasilar anastomoses such as a PPTA are relatively rare vascular anomalies, if the persistent primitive artery is present, it can be an access route for mechanical thrombectomy for acute ischemic stroke.

    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. PMID:27766029

    Intra-arterial injection of sclerosants is a significant but uncommon complication of sclerotherapy that may result in extensive tissue necrosis and in rare cases digit or limb amputation. We have managed three cases in the past 10 years. One patient was referred for immediate treatment following intra-arterial injection of liquid polidocanol. The other two had undergone foam sclerotherapy with polidocanol and sodium tetradecyl sulphate, respectively. All patients were treated with a combination of oral steroids (prednisone 0.5-1 mg/kg) and systemic anticoagulants (enoxaparin 1.5 mg/kg daily subcutaneous injection). One case progressed to skin ulceration where prednisone was started five days after the adverse event and prematurely stopped after four weeks. The other cases did not progress to necrosis or other long-term sequelae. In these patients, prednisone was commenced immediately and slowly reduced over the following 12 weeks. The inflammation that follows ischemia plays a significant role in tissue necrosis and the immediate management of this adverse event may benefit from anti-inflammatory measures and in particular systemic steroid therapy unless contraindicated.

    A 56-year-old man presented with a giant serpentine aneurysm arising from the middle cerebral artery (MCA) manifesting as right hemiparesis and motor aphasia. Magnetic resonance imaging and digital subtraction angiography identified the giant serpentine aneurysm arising from the MCA. The patient was treated surgically. Temporary clipping of the distal channel induced thrombosis in the vascular channel, and the thrombosis was aspirated with an ultrasonic suction device after superficial temporal artery-MCA anastomosis. This case shows that initial occlusion of the distal channel is effective to treat giant serpentine aneurysm. PMID:19246869

    Behcet's disease is a rare autoimmune vasculitis characterized by oral aphthosis, genital ulcers, and ocular and cutaneous lesions. Vascular involvement usually affects the veins more commonly than the arteries, and coronary arterial involvement is extremely rare. We report an adolescent with Behcet's disease who developed a large pseudoaneurysm of the left anterior descending coronary artery requiring a coronary arterial bypass graft.

    Patient: Male, 31 Final Diagnosis: Intraparenchymal pseudo-aneurysms in kidney transplant Symptoms: Asymptomatic Medication: — Clinical Procedure: Percutaneous renal biopsy Specialty: Transplantology Objective: Diagnostic/therapeutic accidents Background: Percutaneous needle biopsy is routinely performed for renal allograft management. Vascular complications of the procedure include pseudoaneurysm and arterio-venous fistulae formation. Delayed diagnosis of these complications is due to their mostly asymptomatic and indolent nature. Case Report: We present a case of extensive intraparenchymal pseudoaneurysm formation within the inferior pole of the allograft, diagnosed two years following the most recent biopsy procedure. Conclusions: Renal pseudoaneurysms may only be diagnosed years after their formation as they are typically asymptomatic. PMID:27510594

    A 68-year-old female patient was treated for unhealed ulcer in the fourth toe of the left foot. Clinical examinations identified severe stenosis of the proximal segment and occlusion of the distal segment of the left anterior tibial artery, and occlusion of the left posterior tibial artery and the peroneal artery. The proximal stenotic segment of the left anterior tibial artery was dilated, but the distal occlusive part failed to be re-canalized. Left anterior tibial artery to dorsal pedal artery bypass was performed on the patient with an epoxide-crosslinked, special radicals antigen-sealed, porcine-derived biological graft; debridement of the left 4th digiti pedis was also performed. Postoperation course was uneventful. The pulse of the left dorsal pedal artery was strong. The ankle brachial index (ABI) increased from 0.60 to 1.09. Warfarin and two antiplatelet drugs were given after the operation. Six months after operation, computed tomographic angiogram (CTA)identified the patent graft.

    Vascular complications of tuberculous infections are rare and occur even less frequently in the pediatric population. Tuberculous pseudoaneurysms can occur either as a result of contiguous spread from a neighboring focus-invariably infected lymph nodes-or by hematogenous spread and seeding of acid-fast bacilli that lodge in the adventitia or media via the vasa vasorum. We report a case of turberculous right common iliac artery pseudoaneurysm in a 12-year-old and review the relevant literature.

    Full text: The prognosis of untreated hepatocellular carcinoma (HCC) is dismal with a median survival of less than two months having been reported. {sup 131}l labelled Lipiodol as a treatment for hepatocellular carcinoma (HCC) has been shown to be as efficacious as intraarterial chemotherapy but with less toxicity than chemotherapy. 23 patients (19 men and four women, mean age 69 years, range 28 to 80 years) with unresectable Okuda Stage I (n = 23) or 11 (n = 2) HCC were treated over a three-year period. All patients had biopsy proved HCC and had not received any prior therapy. Before therapy, all patients underwent CT scans of abdomen and thorax and scintigraphic bone scans to exclude extrahepatic disease. Further, CT scanning of the liver was performed following the hepatic artery injection of unlabelled Lipiodol to ensure that the HCC was Lipiodol avid. 1 GBq of {sup 131}l labelled Lipiodol was injected into the hepatic artery followed by CT liver scanning at day 1 and day 60 to calculate tumour response. Whole body scintigraphic scanning was performed on days 1 and 21 for dosimetry calculations. Ten patients had a second dose of {sup 131}l Lipiodol due either increasing serum alpha feto-protein levels and/or tumour progression on CT scanning. Minimal toxicity was seen with this dose regime. Survival time was estimated from the time of treatment by the Kaplan-Meier method. For Okuda I, the median survival length was 12 months with actuarial survival rates of 91 per cent, 65 per cent, 59 per cent and 20 per cent at 3,6,9,12 and 24 months respectively. All Okuda II patients died within five months. Iodine-131 Lipiodol therapy is well tolerated and may prolong survival in certain HCC patients.

    A 17-year-old patient underwent total arch replacement for aortic arch aneurysm due to vascular Behcet's disease (BD). Follow-up computed tomography, performed 6 months after the operation, demonstrated pseudoaneurysm formation at the proximal anastomotic site. We performed endovascular treatment and used a short stent graft that was originally designed for abdominal aortic aneurysm. To avoid the occlusion of the coronary or brachiocephalic artery (BCA) due to stent graft migration, we used right ventricular rapid pacing and BCA ballooning. Thus, we believe that endovascular treatment can be used for anastomotic complications in the ascending aorta after open surgery for connective tissue disorders including BD. PMID:27174345

    Purpose: This study describes several cases of endovascular coil embolization of the proximal internal mammary artery injured by blind approach to the subclavian vein for central venous catheter or pacemaker lead insertion. Materials and methods: We conducted a retrospective analysis of five patients with iatrogenic arterial lesions of the internal mammary artery (IMA). The lesions occurred in three patients from a puncture of the subclavian vein during insertion of a central venous catheter and in two patients from a puncture of the subclavian vein for insertion of a pacemaker lead. Four patients had acute symptoms of bleeding with mediastinal hematoma and hematothorax and one patient was investigated in a chronic stage. A pseudoaneurysm was detected in all five patients. All four acute and hemodynamic unstable patients required hemodynamic support. Results: In all patients, embolization was performed using a coaxial catheter technique, and a long segment of the IMA adjacent distally and proximally to the source of bleeding was occluded with pushable microcoils. In one patient, additional mechanically detachable microcoils were used at the very proximal part of the IMA. Microcoil embolization of the IMA was successful in all patients, and the source of bleeding was eliminated in all patients. Conclusion: Transarterial coil embolization is a feasible and efficient method in treating acute bleeding and pseudoaneurysm of the IMA and should be considered if mediastinal hematoma or hemathorax occurs after blind puncture of the subclavian vein.

    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.)

    International Nuclear Information System (INIS)

    Objective: To discuss the clinical application of radiofrequency ablation combined with bronchial artery infusion of docetaxel in treating non-small cell lung cancer and to summarize the experience of using this therapy in clinical practice. Methods: Radiofrequency ablation was performed in twenty-one patients with lung cancer. The diagnosis was confirmed by CT-guided percutaneous needle biopsy or bronchoscopic biopsy in all patients. One week after radiofrequency ablation treatment, bronchial artery infusion of docetaxel was conducted. The therapeutic results were observed and evaluated. Results: After the treatment, the lesion's size was markedly reduced and the clinical symptoms were dramatically improved in all patients. Conclusion: Radiofrequency ablation combined with bronchial artery infusion of docetaxel is a safe, effective and simple technique with excellent therapeutic results for the treatment of non-small cell lung cancer. It is really worth popularizing this technique in clinical practice. (authors)

  6. The clinical application of uterine arterial infusion and embolization in treating placenta percreta

    International Nuclear Information System (INIS)

    Objective: To evaluate uterine arterial methotrexate (MTX) infusion together with embolization in treating placenta percreta, and to compare its result with that by using intramuscular injection of MTX. Methods: Sixteen postpartum patients with placenta precreta encountered in author's hospital during the period of Feb. 2005 to Dec. 2009 were enrolled in this study. The patients were divided into two groups. Patients in group A (n = 8) received uterine arterial MTX infusion together with embolization, which was followed by uterine curettage in 7 days after the procedure under the monitoring of Doppler B-ultrasound to clean up the residual placenta. Patients in group B received pure intramuscular injection of MTX, which was followed by uterine curettage as patients in group A. All the patients were not discharged until the virginal bleeding stopped. The serum level of β-human chorionic gonadotropin (β-hCG) and the residual placenta tissue in uterine cavity were followed up. The results were compared between two groups. Results: Technical success with single catheterization was obtained in all eight patients in group A. The average time for hemostasis was (26.0 ± 6.4) minutes and the average operation time was (46.4 ± 7.5) minutes. The serum β-hCG decreased to normal range within 3-7 days after the treatment,with a mean of (5.6 ± 0.6) days. The placenta tissue was successfully cleaned up by uterine curettage within 5-10 days, with a mean of (7.2 ± 0.7) days. No uterine infection and uterine cavity adherence occurred. The menses returned to regular cycle in 4 patients after they stopped breast-feeding in 1-3 months, in another 4 patients their menses regained normal within 3 months. Two patients in group B had to receive hysterectomy because of massive bleeding due to failure to intramuscular injection of MTX. The average time for hemostasis was (28.1 ± 5.5) days and the average treatment time was (10.5 ± 2.5) days. The serum β-hCG decreased to normal range

    Single coronary artery arising from aortic root, is a rare congenital anomaly. A 30-year-old male presented with acute myocardial infarction (MI) complaining of chest pain and raised troponin levels. Emergency angiography showed no coronary lesions but both left and right coronary arteries arising from single ostium. Patient was operated electively and perioperative findings confirmed the diagnosis of single coronary artery, as left coronary artery after taking origin from right sinus of valsalva runs through the septum, before dividing into left anterior descending and circumflex branches. The single coronary ostium opened with a slit like incision over the course of left main coronary, making the size of ostium three to four times bigger than the native one. In addition left internal mammary artery was harvested and grafted to the left anterior descending branch distally. Patient made successful recovery. Four months follow up dobutamine stress echo showed no inducible ischemia.

    This study aims to explore the treatment methods for patients with abdominal aortic aneurysms (AAAs) that required occlusion of the openings of the bilateral internal iliac arteries (IIAs) in endovascular aneurysm repair (EVAR) and to evaluate the efficacy of these treatments. Four patients with AAA were treated with endovascular aneurysm repair (EVAR) and the crossover chimney technique in the bilateral internal iliac arteries (IIAs). We inserted and released the abdominal aortic stent as usual and implanted the bypass stent graft simultaneously. The intraoperative immediate angiography showed complete isolation of the AAA and patency of the bypass. One month after surgery, it showed contrast engorgement in the bypass stent in three patients. The IIA on the bypass side and its branches had good developing. Another case in which we utilized a COOK stent, occlusion started at the opening of the bypass stent, with no occurrence of other complications. For patients in whom AAAs involve bilateral iliac arteries and the openings of the bilateral IIAs need to be occluded, EVAR and a crossover chimney technique can protect the unilateral IIA.

    Full Text Available Abstract Background Tyrosine kinase inhibitors (TKIs are currently approved for the treatment of metastatic renal cell carcinoma (mRCC. The cardiotoxic effects of sorafenib and sunitinib may cause hypertension, left ventricular ejection fraction (LVEF dysfunction and/or congestive heart failure (CHF, and arterial thrombo-embolic events (ATE. Only three cases of coronary artery disease related to sorafenib therapy have been described in the literature, and all were due to arterial vasospasm without evidence of coronary artery stenosis on angiography. Cardiotoxicity is commonly associated with the presence of cardiovascular risk factors, such as a history of hypertension or coronary artery disease. Case presentation We describe a patient who experienced an unusual cardiac event after 2 years of sorafenib treatment. A 58-year-old man with mRCC developed acute coronary syndrome (ischemia/infarction associated with critical sub-occlusion of the common trunk of the left coronary artery and some of its branches, which was documented on coronary angiography. The patient underwent triple coronary artery bypass surgery, and sorafenib treatment was discontinued. He did not have any cardiovascular risk factors, and his cardiac function and morphology were normal prior to sorafenib treatment. Conclusions Further investigation of a larger patient population is needed to better understand cardiac damage due to TKI treatment. Understanding the usefulness of careful cardiovascular monitoring might be important for the prevention of fatal cardiovascular events, and to avoid discontinuation of therapy for the underlying cancer.

    OBJECT The revascularization technique, including bypass created using the external carotid artery (ECA), radial artery (RA), and M2 portion of middle cerebral artery (MCA), has remained indispensable for treatment of complex aneurysms. To date, it remains unknown whether diameters of the RA, superficial temporal artery (STA), and C2 portion of the internal carotid artery (ICA) and intraoperative MCA blood pressure have influences on the outcome and the symptomatic watershed infarction (WI). The aim of the present study was to evaluate the factors for the symptomatic WI and neurological worsening in patients treated by ECA-RA-M2 bypass for complex ICA aneurysm with therapeutic ICA occlusion. METHODS The authors measured the sizes of vessels (RA, C2, M2, and STA) and intraoperative MCA blood pressure (initial, after ICA occlusion, and after releasing the RA graft bypass) in 37 patients. Symptomatic WI was defined as presence of the following: postoperative new neurological deficits, WI on postoperative diffusion-weighted imaging, and ipsilateral cerebral blood flow reduction on SPECT. Neurological worsening was defined as the increase in 1 or more modified Rankin Scale scores. First, the authors performed receiver operating characteristic curve analysis for continuous variables and the binary end point of the symptomatic WI. The clinical, radiological, and physiological characteristics of patients with and without the symptomatic WI were compared using the log-rank test. Then, the authors compared the variables between patients with and without neurological worsening at discharge and at the 12-month follow-up examination or last hospital visit. RESULTS Symptomatic WI was observed in 2 (5.4%) patients. The mean MCA pressure after releasing the RA graft (< 55 mm Hg; p = 0.017), mean (MCA pressure after releasing the RA graft)/(initial MCA pressure) (< 0.70 mm Hg; p = 0.032), and mean cross-sectional area ratio ([RA/C2 diameter](2) < 0.40 mm [p < 0.0001] and [STA/C2

    Full Text Available A 58-year-old female with a history of Wolff-Parkinson-White syndrome presented at our institution with palpitations and chest pain. Electrocardiography revealed paroxysmal supraventricular tachycardia with a heart rate of 188 beats/min. Antiarrhythmic drugs were ineffective, and tachycardia was resolved by electrical cardioversion. Transthoracic echocardiography revealed abnormal vessels around the right coronary artery (RCA and pulmonary artery (PA; in addition, we suspected coronary arteriovenous fistula (CAVF. Coronary angiography and coronary computed tomography revealed dilated fistula vessels, with a 1 cm saccular aneurysm around the RCA, originating from the proximal RCA and left anterior descending artery into the main trunk of PA. Therefore, we confirmed the diagnosis of CAVF with an unruptured aneurysm. We surgically ligated and clipped the fistula vessels and resected the aneurysm. The resected aneurysm measured  cm in size. Pathological examination of the resected aneurysm revealed hypertrophic walls comprising proliferating fibroblasts cells thin elastic fibers. Very few atherosclerotic changes manifested in the aneurysm walls. We report the case of a patient with CAVF and an unruptured coronary artery aneurysm who was successfully treated by surgery.

    International Nuclear Information System (INIS)

    Objective: To discuss the clinical nursing care for patients with pelvic neoplasm who were treated with infusion chemotherapy by using an anti-reflux arterial port-catheter system. Methods: After the implantation of an anti-reflux arterial port-catheter system was successfully completed, intra-arterial infusion chemotherapy was carried out in 17 patients with pelvic neoplasm and the infusion chemotherapy was repeated for several times. The pre-procedural clinical nursing care was well done and the technique of proper placement was well grasped. The side effects of chemotherapy drugs and complications were dealt with in time. Medical orientation at discharge time included the protection methods for port-catheter system. Results: Seventeen patients received infusion chemotherapy successfully several times (ranged from 3 to 8 times) with a scheduled regular interval time. No severe complications occurred. No catheter leakage nor obvious irritation and compression symptoms of local skin developed during infusion period. Of the 17 patients, 6 had a complete response, 9 achieved a partial response, while the remaining 2 failed to respond. Conclusion: In accordance with characteristics of infusion chemotherapy by using an anti-reflux arterial port-catheter system, the reasonable and effective nursing care is important to guarantee the achievement of a successful performance and a satisfactory therapeutic result.

    Bleeding from gastric varices due to splenic vein obstruction is extremely rare in children, but it can be catastrophic. Reported herein is the case of a teenager with splenic vein thrombosis and chronic decompensated liver disease from autoimmune hepatitis who presented with massive gastric variceal bleeding. Standard medical management did not control the bleeding. Due to decompensated liver disease and continuous active bleeding, emergency partial splenic artery embolization was preferred over splenectomy or a shunt procedure. Bleeding was successfully controlled by partial splenic artery embolization by decreasing the inflow of blood into the portal system. It is concluded that emergency partial splenic artery embolization is a safer alternative life-saving procedure to manage severe gastric variceal bleeding due to splenic vein obstruction in a patient with high surgical risk. To our knowledge, only one other patient with similar management has been reported in the pediatric age group.

    Conclusion: Surgeons should pay attention to any displaced bone fragments close to calcified vessels, especially in the evaluation of routine x-rays following surgical treatment of fractures. This could minimize the potential life-threatening risk of delayed diagnosis, especially because it represents a routine image following surgical fracture treatments.

  19. Limb-Shaking Transient Ischemic Attacks Successfully Treated with External Carotid Artery Stenting

    George N. Kouvelos

    2012-01-01

    Full Text Available The external carotid artery (ECA is one of the most important extracranial-to-intracranial sources of collateral circulation, contributing significantly to the cerebral blood flow especially when perfusion through the internal carotid artery (ICA is compromised. Most of the endovascular studies so far have been dedicated to ICA, with little focus on the ECA. Limb-shaking transient ischemic attacks (TIAs are a relatively rare manifestation of carotid artery disease that may present with repetitive shaking movements of the affected limbs. We report a case of an 80-year-old male with bilateral internal and contralateral external carotid artery occlusion who developed limb-shaking TIAs as a result of significant stenosis of the right ECA. Percutaneous revascularization of the ECA was performed by angioplasty and stenting. At the follow-up 12 months later, the patient remained neurologically intact with complete resolution of his symptoms. Stenting of the ECA should be considered as a reasonable alternative to conventional open repair especially in patients with contralateral carotid stenosis, insufficient circle of Willis, and significant comorbidities.

    Full Text Available Background: Fusiform aneurysms of cerebellar arteries are rare. Different surgical techniques to address these challenging lesions have been described, and their application depends on whether the goal is to maintain the flow in the parent vessel or to occlude it. Case Description: The authors reported a case of a fusiform aneurysm located in the lateral pontomesencephalic segment of the superior cerebellar artery (SCA in a 32-year-old man who presented with subarachnoid hemorrhage. The patient was subjected to aneurysm trapping followed by a bypass between the superficial temporal artery (STA and SCA and had an uneventful recovery. Conclusions: Although only a few cases of fusiform aneurysms in the supracerebellar artery have been reported in the literature, the treatment strategies adopted were diverse. In selected cases of patients in good neurological condition with ruptured fusiform aneurysms at the proximal segments of SCA and who have poor evidence of collateral supply, the possibility of a STA-SCA bypass with aneurysm trapping must be considered. A review of the current treatment modalities of this pathology is also presented.

    Fetal brain perfusion is supplied by the primitive dorsal aorta anteriorly, longitudinal neural arteries posteriorly, and anastomotic transverse segmentals. Most notable of these connections are the primitive trigeminal, otic, hypoglossal, and proatlantal arteries. With cranial-cervical circulatory maturation and development of the posterior communicating segments and vertebro-basilar system, these primitive segmental anastomoses normally regress. Anomalous neurovascular development can result in persistence of these anastomoses. Due to its territory of perfusion, the persistent primitive hypoglossal artery (PPHA) is associated with vertebral artery and posterior communicating artery hypoplasia or aplasia. As a consequence, primary blood supply to the hindbrain comes chiefly from this single artery. Although usually clinically silent, PPHA is susceptible to common cerebrovascular disorders including athero-ischemic disease and saccular aneurysmal dilation to name a few. We present a case of transient ischemic attack in a patient with a PPHA and proximal atherosclerotic disease treated by endovascular stenting. PMID:26929891

    Ischemic strokes in childhood are rare. Thrombolytic therapy with intravenous (IV) tissue plasminogen activator (tPA) has been the main intervention for the management of pediatric stroke patients, but safety data are lacking and efficacy has been questioned. Recently, successful endovascular treatments for acute ischemic stroke in children have been reported with increasing frequency, suggesting that mechanical thrombectomy can be a safe and effective treatment. We present the case of a 22-month-old child with acute ischemic stroke due to basilar artery occlusion that was successfully treated with a stent retriever. PMID:26156170

    Use of endovascular means is gaining ever greater acceptance in the treatment of aorto-iliac aneurysms. Especially, the treatment of patients with common iliac aneurysms (CIAs) may be very challenging due to the complexity of the underlying disease with often involvement of the hypogastric artery. Additionally, the variety of endovascular therapeutic options such as the use of iliac branch devices, parallel grafts, the bell-bottom technique or coil embolization of the hypogastric artery and overstenting of the origin represents significant limitation regarding the presentation of a clear and robust endovascular therapeutic algorithm. Aim of the present article was the demonstration of the institutional experience with the endovascular management of CIAs in order to provide a clinical recommendation and algorithm. PMID:27406396

    Gelatin sponge particles are commonly used in the conventional transarterial chemoembolization (c-TACE) as an adjuvant embolizing agent for hepatocellular carcinoma (HCC). However, there are few reports regarding the clinical applications of gelatin sponge microparticles (GSMs) as a main embolizing agent in the treatment of HCC. This retrospective study aim to evaluate the efficacy and safety of patients with Barcelona Clinic Liver Cancer (BCLC) stage B HCC treated with intra-arterial injection of 350 to 560 μm GSMs mixed with anticancer agents.Twenty-four patients with unresectable BCLC stage B HCC without any prior treatment underwent transarterial chemoembolization with gelatin sponge microparticles (GSMs-TACE) of diameter 350 to 560 μm mixed with lobaplatin. The mixture was injected into tumor-feeding arteries until the sluggish flow in selective artery. Safety was measured by assessing complication rate, and efficacy was reflected by assessing response to mRECIST therapy and overall survival. The survival rate was calculated using the Kaplan-Meier method.All 24 BCLC stage B HCC patients showed good tolerance to the procedure. The mean follow-up period was 27 months and mean number of TACE treatments per patient was 3.7 sessions (range 1-10) during the follow-up period. Postprocedure complications were mild and treated by symptomatic treatment. Six months and 1 year overall survival rates were 100% and 87.5%, respectively. Overall median survival time was 25 months (95%CI: 21.06-28.95 months).GSMs-TACE is a safe and effective method for BCLC stage B HCC patients.

    Objective To discuss the value of super-selective arterial embolization in treating renal hemorrhage caused by iatrogenic injuries. Methods During the period from Dec. 2009 to Feb. 2012, a total of 11 patients with renal hemorrhage caused by iatrogenic injuries were admitted to authors' hospital. The iatrogenic injuries included nephrostomy (n = 3), percutaneous nephrolithotomy(n = 3) partial nephrectomy for renal tumors (n=3) and holmium laser therapy (n = 2). By using super - selective catheterization technique, the catheter was placed into the bleeding artery, which was followed by embolization management with PVA particles, coils and/or micro-coils. Results The embolization was successfully accomplished with single manipulation in all patients. Angiography demonstrated that arteriovenous fistula, contrast extravasation and retention, the formation of pseudoaneurysm, etc. existed in diseased kidney. The hemorrhage disappeared soon after the embolization treatment and no obvious renal dysfunction was seen in all patients. During the clinical follow-up period lasting for 4 — 35 months, no recurrent hemorrhage occurred. Conclusion For the treatment of renalhemorrhage due to iatrogenic injuries, super - selective arterial embolization is safe and effective. This technique should be recommended in clinical practice.%目的 探讨超选择性动脉栓塞在医源性损伤导致的肾出血中的应用价值.方法 2009年12月至2012年2月收治11例医源性损伤导致的肾出血患者,其中肾造瘘术后出血3例,经皮肾镜取石术术后出血3例,肾肿瘤部分性肾切除术后出血3例,钬激光术后2例.采用超选择方法将导管置于出血动脉,用聚乙烯醇颗粒及弹簧圈或(和)微弹簧圈栓塞治疗.结果 所有患者均一次性成功进行出血动脉栓塞治疗,造影过程中可见动静脉瘘,对比剂外溢、滞留及假性动脉瘤形成.所有患者在栓塞治疗后出血症状均消失,未观察到明显

  8. Treatment of Intra- and Extracranial Arterial Dissections Using Stents and Embolization

    International Nuclear Information System (INIS)

    Purpose. To evaluate the safety and efficacy of stent placement for extracranial and intracranial arterial dissections. Methods. Eighteen patients underwent endovascular treatment of carotid and vertebral dissections using intraluminal stent placement. Five patients with arterial dissection were treated, 2 using one insertion of a single stent and 3 using placement of two stents. Patients with a dissecting aneurysm were treated as follows: 7 patients with insertion of one stent, 4 with placement of two stents, and 2 by stent-assisted Guglielmi detachable coil embolization. In the 18 patients in whom stenting was attempted, the overall success in reaching the target lesion was 94.4%. Of the 17 patients treated with stents, stent release and positioning were considered optimal in 16 (94%) and suboptimal in one (6%). In patients who underwent a successful procedure, all parent arteries were preserved. There were no instances of postprocedural ischemic attacks, new neurologic deficits, or new minor or major strokes prior to patient discharge. In follow up, all patients were assessed, using the modified Rankin scale, as functionally improved or of stable clinical status. The reduction in dissection-induced stenosis or pseudoaneurysm, the patency rate obtained at follow-up, and the lack of strokes (ischemic or hemorrhagic) suggest that stent placement offers a viable alternative to complex surgical bypass or reconstructive procedures. The long-term efficacy and durability of stent placement for arterial dissection remain to be determined in a larger series

    Highlights: • Symptomatic vertebral artery stenosis can be treated with intracranial stenting. • Stenting for intracranial vertebral artery stenosis is safe and effective. • Stenting for intracranial vertebral artery stenosis can prevent long-term stroke. - Abstract: Purpose: To investigate the safety, effect and instent restenosis rate of Wingspan stenting in treating patients with intracranial vertebral artery atherosclerotic stenosis (70–99%) concurrent with contralateral vertebral artery atherosclerotic diseases. Materials and methods: Eighty-eight patients with severe symptomatic intracranial vertebral artery atherosclerotic stenosis (≥70%) combined with contralateral vertebral artery atherosclerotic diseases were treated with the Wingpsan stent. All the baseline, cerebral angiography, success rate, perioperative complications, clinical and imaging follow-up data were prospectively analyzed. Results: The success rate of stenting was 100%, and the mean stenotic rate was reduced from prestenting (84.9 ± 6.8)% to poststenting (17.2 ± 5.9)%. The perioperative stroke rate was 1.1%. Among eighty patients (90.9%) with clinical follow-up 8-62 months (mean 29.3 ± 17.2) poststenting, five (6.3%) had posterior circulation TIA only, three (3.8%) had mild stroke in the posterior circulation but recovered completely, and another five patients greater than 70 years old died of non-ischemic stroke. Imaging follow-up in 46 patients (52.3%) 5–54 months (mean 9.9 ± 9.9) following stenting revealed instent restenosis in 12 patients (26.1%) including 7 (58.3%) symptomatic restenosis. Age and residual stenosis were the two factors to significantly (P < 0.05) affect instent restenosis. Conclusion: Wingspan stenting in the intracranial vertebral artery atherosclerotic stenosis combined with contralateral vertebral artery atherosclerotic diseases has a low perioperative stroke rate and a good preventive effect on long-term ischemic stroke, but the instent restenosis

  11. Feasibility and Safety of Vascular Closure Devices in an Antegrade Approach to Either the Common Femoral Artery or the Superficial Femoral Artery

    International Nuclear Information System (INIS)

    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.

    Nanoscale topography in improving vascular response in vitro was established previously on various titanium surfaces. In the present study different surface nanotopographies that is different diameters of titanium dioxide (TiO2 ) nanotubes (NTs) were fabricated by electrochemical anodization and conditioned with highly reactive gaseous oxygen plasma. The morphology of different diameter NTs was studied by scanning electron microscopy and atomic force microscopy, while changes in chemical composition on the surface before and after plasma treatment were determined by X-ray photoelectron spectroscopy. Performance of human coronary artery endothelial cells (HCAEC) on those conditioned surfaces was studied in regard to cell proliferation, released IL-6 protein and immunofluorescence microscopy (IFM). We show that HCAEC function is dependent on the diameter of the TiO2 NTs, functioning far less optimally when bound to 100 nm TiO2 NTs as compared to Ti foil, 15 nm NTs or 50 nm NTs. There were improved, morphological cell shape changes, observed with IFM, between HCAEC growing on oxygen-rich plasma-treated versus nontreated 100 nm NTs. These endothelialized conditioned Ti nanosurfaces could elucidate optimization conditions necessary for vascular implants in coronary arteries. © 2016 Wiley Periodicals, Inc.

    Full Text Available Abstract Introduction Splenic vein thrombosis results in localized portal hypertension called sinistral portal hypertension, which may also lead to massive upper gastrointestinal bleeding. Symptomatic sinistral portal hypertension is usually best treated by splenectomy, but interventional radiological techniques are safe and effective alternatives in the management of a massive hemorrhage, particularly in cases that have a high surgical risk. Case presentation We describe a 23-year-old Greek man with acute massive gastric variceal bleeding caused by splenic vein thrombosis due to a missing von Leiden factor, which was successfully managed with splenic arterial embolization. Conclusions Interventional radiological techniques are attractive alternatives for patients with a high surgical risk or in cases when the immediate surgical excision of the spleen is technically difficult. Additionally, surgery is not always successful because of the presence of numerous portal collaterals and adhesion. Splenic artery embolization is now emerging as a safe and effective alternative to surgery in the management of massive hemorrhage from gastric varices due to splenic vein thrombosis, which often occurs in patients with hypercoagulability.

    Nanoscale topography in improving vascular response in vitro was established previously on various titanium surfaces. In the present study different surface nanotopographies that is different diameters of titanium dioxide (TiO2 ) nanotubes (NTs) were fabricated by electrochemical anodization and conditioned with highly reactive gaseous oxygen plasma. The morphology of different diameter NTs was studied by scanning electron microscopy and atomic force microscopy, while changes in chemical composition on the surface before and after plasma treatment were determined by X-ray photoelectron spectroscopy. Performance of human coronary artery endothelial cells (HCAEC) on those conditioned surfaces was studied in regard to cell proliferation, released IL-6 protein and immunofluorescence microscopy (IFM). We show that HCAEC function is dependent on the diameter of the TiO2 NTs, functioning far less optimally when bound to 100 nm TiO2 NTs as compared to Ti foil, 15 nm NTs or 50 nm NTs. There were improved, morphological cell shape changes, observed with IFM, between HCAEC growing on oxygen-rich plasma-treated versus nontreated 100 nm NTs. These endothelialized conditioned Ti nanosurfaces could elucidate optimization conditions necessary for vascular implants in coronary arteries.

    Full Text Available Background: Combined central retinal artery occlusion (CRAO and central retinal vein occlusion (CRVO is an uncommon retinal vascular disease which causes sudden visual acuity loss and is associated with poor prognosis and the development of severe complications. We report a very rare case of combined CRAO and CRVO in a patient with factor V Leiden (FVL mutation (only 3 cases published. To our knowledge, this is the first case of combined CRAO and CRVO treated with hyperbaric oxygen therapy (HBOT. Case and Results: A 49-year-old woman presented with complaints of sudden loss of vision in her left eye (LE, with best corrected visual acuity (BCVA of 1/20. A complete ophthalmic evaluation with fundus angiography showed combined CRAO and CRVO. The patient was urgently treated with HBOT (she completed a total of 9 sessions in 7 days, with marked visual acuity and angiographic improvement (BCVA of 10/10. Forty-five days later, she developed a new LE CRVO, and BCVA decreased to 5/10 and later to Conclusions: Combined CRAO and CRVO in young adults should be investigated thoroughly for embolic sources, thrombophilic disorders and local ocular conditions. This is the first case of this severe disease that was treated with HBOT, and the visual result was very good.

    To evaluate the effectiveness of interventional management for delayed and massive hemobilia secondary to arterial erosion self expandable metallic stent (SES) in with biliary duct malignancy. Over 8-year period, eight patients who suffered from delayed massive hemobilia after SES placement for malignant biliary obstruction as palliative procedure, were included. The mean period between SES placement and presence of massive gastrointestinal hemorrhage was 66.5 days (15-152 days), pancreatic cancer (n = 2), Klatskin tumor (n = 2), common bile duct cancer (n = 2), intrahepatic cholangiocarcinoma (n = 1), and gastric cancer with ductal invasion (n = 1). Angiographic findings were pseudoaneurysm (n = 6), contrast extravasation (n = 1) and arterial spasm at segment (n = 1). Six patients underwent embolization of injured vessels using microcoils and N-butyl cyanoacrylate. Two patients underwent stent graft placement at right hepatic artery to prevent ischemic hepatic damage because of the presence of portal vein occlusion. Massive hemobilia was successfully controlled by the embolization of arteries (n = 6) and stent graft placement (n = 2) without related complications. The delayed massive hemobilia to arterial erosion metallic biliary stent is rare this complication be successfully treated by interventional management.

    PurposeTo evaluate the safety and efficacy of transarterial embolization of life-threatening arterial rupture in patients with vascular Ehlers–Danlos syndrome (vEDS) in a single tertiary referral center.MethodsWe retrospectively analyzed transarterial embolization for vEDS performed at our institution from 2000 to 2012. The indication of embolization was spontaneous arterial rupture or pseudoaneurysm with acute bleeding. All interventions used a percutaneous approach through a 5F or less introducer sheath. Embolic agents were microcoils and glue in 3 procedures, glue alone in 2, and microcoils alone in 2.ResultsFive consecutive vEDS patients were treated by 7 embolization procedures (4 women, mean age 29.8 years). All procedures were successfully performed. Two patients required a second procedure for newly arterial lesions at a different site from the first procedure. Four of the five patients were still alive after a mean follow-up of 19.4 (range 1–74.7) months. One patient died of multiple organ failure 2 days after procedure. Minor procedural complications were observed in 3 procedures (43 %), all directly managed during the same session. Remote arterial lesions occurred after 3 procedures (43 %); one underwent a second embolization, and the other 2 were observed conservatively. Puncture site complication was observed in only one procedure (14 %).ConclusionEmbolization for vEDS is a safe and effective method to manage life-threatening arterial rupture.

    Whether biomarkers associated with cardiovascular disease risk also predict incident diabetes mellitus (DM) is unknown. Our objective was to determine if a panel of 18 biomarkers previously associated with risk of cardiovascular disease also predicts incident DM in statin-treated patients with coronary artery disease (CAD). The Treating to New Targets (TNT) study is a randomized trial that compared the efficacy of high (80 mg) versus low (10 mg) dose atorvastatin for the secondary prevention of coronary heart disease events. Fasting plasma levels of standard lipids and of 18 emerging CAD risk biomarkers were obtained after an 8-week run-in period on atorvastatin 10 mg in a random sample of 1,424 TNT patients. After exclusion of patients with DM at baseline (n = 253), 101 patients developed DM during the median follow-up of 4.9 years. Patients with incident DM had lower levels of total and high-molecular weight adiponectin, lipoprotein-associated phospholipase A2 (Lp-PLA2), soluble receptor of advanced glycation end products, and vitamin D compared with patients without incident DM. In contrast, insulin, soluble CD40 ligand, and soluble intercellular adhesion molecule-1 levels were higher in patients with incident DM compared with those without. Plasma levels of C-reactive protein, cystatin C, lipoprotein(a), monocyte chemotactic protein-1, matrix metalloproteinase-9, myeloperoxidase, neopterin, N-terminal fragment of pro-B-type natriuretic peptide, osteopontin, and soluble vascular cell adhesion molecule-1 were comparable in patients with and without incident DM. After multivariate adjustment, total and high-molecular weight adiponectin as well as Lp-PLA2 were negatively associated with incident DM. Results of this study suggest that plasma lipids and some emerging CAD risk biomarkers, such as adiponectin and Lp-PLA2, may be useful for predicting incident DM in statin-treated patients with stable CAD.

    2012-01-01

    Full Text Available We present the endovascular treatment of traumatic carotid-cavernous fistula from persistent fetal trigeminal artery (PFTA laceration. To date, there are six such cases of traumatic PFTA-cavernous fistulas reported in the literature. These injuries can pose a unique challenge in that rupture of a PFTA in its course through the cavernous sinus may produce a fistula feeding from both anterior and posterior circulations. Previously, these have been treated with dual catheter coil embolization from the carotid and basilar systems. We utilize a single catheter technique accessing the cavernous sinus through the origin of the PFTA on the internal carotid. Both anterior and posterior fistula components may be embolized through this single access. This represents a simple yet safe treatment option.

  3. Experimental research on treating hepatic carcinoma by trans-arterial delivery of p53 gene mediated by lipsome combined transferring

    International Nuclear Information System (INIS)

    Objective: To investigate the trans-arterial delivery of p53 gene transfection efficiency and therapy effect on hepatic carcinoma in combination with transferrin mediated by liposome. Methods: Twenty-five VX2 experimental rabbits were randomly divided into five groups, and the different doses of transferrin combined with p53-LipofectAMINE complex were delivered into the hepatic arteries of the VX2 hepatic carcinoma models. The tissue protein of the carcinoma was extracted after 48 h and the transfection efficiency and expression rate of p53 gene were analyzed by western blot and immune histochemical techniques, to inspect the expression proportion of p53 with different doses transferring. Another ten VX2 were divided into two groups, recombinant plasmid p53-LipofectAMINE complex and transferrin-p53-LipofectAMINE complex were delivered into the hepatic arteries in two groups respectively. The liver function, size of the tumor and survival time of the animals was compared between the two groups, and results were analyzed statistically. Results: Semiquantitative analysis by Western Blot showed that the transfection and expression efficiency of p53 gene combined with transferrin were higher than those without it. By immune histochemical techniques, the p53 gene's positive rate of highly expression with various doses of transferrin were found to be different, and there was remarkable difference between the groups with and without transferring. They were 58.33%, 69.44%, 80.00%, 83.33%, 81.67% respectively, there was remarkable difference between the groups with and without transferring (Totality: χ2=42.37, P2 section: 3 groups as former χ2=4.82, P2=0.67, P<0.05). There was no statistical difference in the liver function at points of time between VX2 rabbits with and without transferring. But the tumor's sizes had significant difference at various points of time. Conclusion: Liposome-mediated p53 gene on treating hepatic carcinoma by trans-arterial gene delivery

    Full Text Available Major advances have occurred in the treatment of pulmonary arterial hypertension (PAH over the past decade. The advent of PAH-specific pharmacological treatments has offered hope to patients with a debilitating, progressive disease and a poor prognosis. Combined drug treatment offers improved benefits over monotherapy, and current treatment guidelines for PAH recommend a sequential add-on approach to combination therapy for patients in New York Heart Association (NYHA/World Health Organization functional class (WHO FC II–IV. Goal-oriented therapy determines the timing of treatment escalation by inadequate response to known prognostic indicators. Close monitoring of patients aids the early identification of inadequate response, so that treatment can be escalated promptly and before the patient's condition deteriorates further. Existing treatment goals are based on baseline values of prognostic indicators, but it is vital to identify risk factors that are both relevant during treatment and that can be assessed during follow-up appointments. Data from different PAH aetiologies indicate that NYHA/WHO FC is the most appropriate prognostic marker, with 6-min walk distance and several haemodynamic parameters representing alternatives. Future refinement of goal-oriented therapy could include the use of multiple prognostic markers, while additional, large clinical trials will answer questions concerning choice and combination of treatment goals.

    Full Text Available Abstract Introduction Axillary artery injury is a rare but severe complication of fractures of the surgical neck of the humerus. Case presentation We present a case of axillary artery pseudoaneurysm secondary to such a fracture, in a 82-year-old white woman, presenting 10 weeks after the initial injury, successfully treated with subclavian to brachial reversed vein bypass together with simultaneous open reduction and internal fixation of the fracture. We discuss the use of a Javid™ shunt during combined upper limb revascularisation and open reduction and internal fixation of the fractured humerus. Conclusion This case highlights the usefulness of a Javid™ shunt, over other forms of vascular shunts, in prompt restoration of blood flow to effect limb salvage. It can be considered as a temporary measure whilst awaiting definitive revascularisation which can be performed following fracture fixation.

    Contrast extravasation on computed tomography angiography (CTA) is rare but becoming more common, with increasing use of CTA for various cerebral vascular diseases. We report on two cases of spontaneous subarachnoid hemorrhage (SAH) in which the CTA showed an upper basilar trunk saccular lesion suggesting ruptured aneurysm. However, immediate subsequent digital subtraction angiography (DSA) failed to show a vascular lesion. In one case, repeated follow up DSA was also negative. The patient was treated conservatively and discharged without any neurologic deficit. In the other case, the patient showed sudden mental deterioration on the third hospital day and her brain CT showed rebleeding. The immediate follow up DSA showed contrast stagnation in the vicinity of the upper basilar artery, suggestive of pseudoaneurysm. Double stents deployment at the disease segment was performed. Due to the frequent use of CTA, contrast extravasation is an increasingly common observation. Physicians should be aware that basilar artery extravasation can mimic the appearance of an aneurysm.

    INTRODUCTION: Hepatic pseudoaneurysm (HPA) is a rare complication after liver trauma, yet it is potentially fatal, as it can lead to sudden severe haemorrhage. The risk of developing posttraumatic HPA is one of the arguments for performing follow-up CT of patients with liver injuries. The aim...... of this study was to investigate the occurrence of HPA post liver trauma. METHODS: A retrospective study from 2000-2010 of conservatively treated patients with blunt liver trauma was performed to investigate the incidence and nature of HPA. After the initial CT scan patients were admitted to the department...... and if not clinically indicated prior a follow-up CT was performed on day 4-5. RESULTS: A total of 259 non-operatively managed patients with liver injury were reviewed. 188 had a follow-up CT or US and in 7 patients a HPA was diagnosed. All aneurysms were treated with angiographic embolization and there were...

    2006-01-01

    Percutaneous liver biopsy is considered one of the most important diagnostic tools to evaluate diffuse liver diseases. Pseudoaneurysm of hepatic artery is an unusual complication after ultrasound-guided percutaneous liver biopsy. Delayed hemorrhage occurs much less frequently. We report a case of pseudoaneurysm of the hepatic artery of a 46-year-old man who was admitted for abdominal pain after 4 d of liver biopsy. The bleeding was controlled initially by angiographic embolization.However, recurrent bleeding could not be controlled by repeat angiography, and the patient died 4 d after admission from multiorgan failure. The admittedly rare possibility of delayed hemorrhage should be considered whenever a liver biopsy is performed.

    Background Combined central retinal artery occlusion (CRAO) and central retinal vein occlusion (CRVO) is an uncommon retinal vascular disease which causes sudden visual acuity loss and is associated with poor prognosis and the development of severe complications. We report a very rare case of combined CRAO and CRVO in a patient with factor V Leiden (FVL) mutation (only 3 cases published). To our knowledge, this is the first case of combined CRAO and CRVO treated with hyperbaric oxygen therapy (HBOT). Case and Results A 49-year-old woman presented with complaints of sudden loss of vision in her left eye (LE), with best corrected visual acuity (BCVA) of 1/20. A complete ophthalmic evaluation with fundus angiography showed combined CRAO and CRVO. The patient was urgently treated with HBOT (she completed a total of 9 sessions in 7 days), with marked visual acuity and angiographic improvement (BCVA of 10/10). Forty-five days later, she developed a new LE CRVO, and BCVA decreased to 5/10 and later to <1/20 because of significant macular edema. A detailed investigation showed an abnormal resistance to activated protein C, and a genetic study showed homozygosity for FVL mutation. The patient was submitted to 3 monthly injections of 1.25 mg bevacizumab. After 10 months, the patient is in a stable condition with BCVA of 6/10. Conclusions Combined CRAO and CRVO in young adults should be investigated thoroughly for embolic sources, thrombophilic disorders and local ocular conditions. This is the first case of this severe disease that was treated with HBOT, and the visual result was very good. PMID:26955350

    The distance to thrombus (DT) on CT angiography was recently proposed as a predictor of outcome in patients treated by intravenous thrombolysis (IVT) for stroke due to occlusion of the middle cerebral artery (MCA). The purpose of the present study was to validate its inter-rater reliability and its prognostic value on contrast-enhanced magnetic resonance angiography (CE-MRA). Furthermore, we investigated the relation between DT and FLAIR-vascular hyperintensities (FVH) as a surrogate of collateral circulation and hypoperfusion. Patients with acute MCA occlusions treated by IVT and diagnosed with magnetic resonance imaging (MRI) were included. Two readers measured DT. FVH and acute DWI lesion volumes were quantified. Clinical status was determined using the initial NIH stroke scale (NIHSS) and 90-day modified Rankin Scale (90d mRS). Sixty-one patients showed a lesion on diffusion-weighted magnetic resonance images and an occlusion of the MCA on CE-MRA. We found significant inverse correlations between DT and NIHSS scores at admission (ρ = -0.29; P = 0.02), DT and mRS at 90 days (ρ = -0.29; P = 0.04), and between DT and FVH (ρ = -0.32; P = 0.01). For a DT <22 mm, the likelihood of an unfavorable outcome (90d mRS 3-6 or NIHSS score improvement of ≤10 points at discharge) was >50 %. Initial DWI lesion volumes showed no correlation with the outcome. Excellent inter-rater agreement for DT was observed (Cronbach's α = 0.98; P < 0.001). DT on CE-MRA is reliably measurable, correlates inversely with FLAIR-vascular hyperintensities, and predicts outcome in patients with acute MCA occlusion treated with IVT. (orig.)

    Saccular intracranial aneurysms occur infrequently in children, and the incidence of pediatric giant aneurysms is statistically in the same proportion as in adults. The management of these giant aneurysms can be treacherous. This paper presents a case of a 9-year-old boy with a giant aneurysm of the right middle cerebral artery that was successfully managed by ligation of the middle cerebral artery using a Drake tourniquet with the patient awake and by augmentation of the middle cerebral artery circulation with superficial temporal artery-middle cerebral artery anastomosis without excision of the lesion.

    Full Text Available Discrepancy was found between enhanced hypotension and attenuated relaxation of conduit arteries in response to acetylcholine (ACh and bradykinin (BK in nitric oxide (NO-deficient hypertension. The question is whether a similar phenomenon occurs in spontaneously hypertensive rats (SHR with a different pathogenesis. Wistar rats, SHR, and SHR treated with NO donors [molsidomine (50 mg/kg or pentaerythritol tetranitrate (100 mg/kg, twice a day, by gavage] were studied. After 6 weeks of treatment systolic blood pressure (BP was increased significantly in experimental groups. Under anesthesia, the carotid artery was cannulated for BP recording and the jugular vein for drug administration. The iliac artery was used for in vitro studies and determination of geometry. Compared to control, SHR showed a significantly enhanced (P < 0.01 hypotensive response to ACh (1 and 10 µg, 87.9 ± 6.9 and 108.1 ± 5.1 vs 35.9 ± 4.7 and 64.0 ± 3.3 mmHg, and BK (100 µg, 106.7 ± 8.3 vs 53.3 ± 5.2 mmHg. SHR receiving NO donors yielded similar results. In contrast, maximum relaxation of the iliac artery in response to ACh was attenuated in SHR (12.1 ± 3.6 vs 74.2 ± 8.6% in controls, P < 0.01. Iliac artery inner diameter also increased (680 ± 46 vs 828 ± 28 µm in controls, P < 0.01. Wall thickness, wall cross-section area, wall thickness/inner diameter ratio increased significantly (P < 0.01. No differences were found in this respect among SHR and SHR treated with NO donors. These findings demonstrated enhanced hypotension and attenuated relaxation of the conduit artery in response to NO activators in SHR and in SHR treated with NO donors, a response similar to that found in NO-deficient hypertension.

    Full Text Available Neonatal thromboembolic events are rare, and only a few cases of intrauterine spontaneous arterial thromboembolisms have been reported in the literature. Thrombolytic therapy with recombinant tissue plasminogen activator is usually the preferred treatment because it has a short half-life, fewer systemic side effects, and a strong, specific affinity for fibrin. Protocols vary from center to center, but there is still no consensus regarding the proper dosage or treatment duration. Herein, we present the case of an intrauterine spontaneous arterial thromboembolism in a preterm infant that completely resolved after being treated with low-dose recombinant tissue plasminogen activator (0.02 mg/kg/h.

    This study was designed to analyze the clinical results in patients suitable for liver transplantation with hepatocellular carcinoma (HCC) who exceeded Milan criteria, which underwent intra-arterial therapies (IAT), to determine predictive factors of successful downstaging. A total of 277 consecutive patients with cirrhosis and HCC were treated by IAT (transarterial oily chemoembolization, transarterial chemoembolization, transarterial embolization) in a single center. Eighty patients exceed the Milan criteria. Patients with infiltrative HCC, hypovascular HCC, and portal vein thrombosis were excluded, with a final study population of 48 patients. Tumor response to IAT was evaluated with CT and/or MRI according to modified RECIST criteria. Successful downstaging was defined as a reduction in the number and size of viable tumors to within the Milan criteria, and serum alpha-fetoprotein (AFP) <100 ng/mL, for at least 6 months. Nineteen patients (39 %) had their tumors successfully downstaged; 29 patients (61 %) did not. Multivariate analysis showed that AFP level <100 ng/mL and 3-year calculated survival probability using the Metroticket calculator were the only independent predictors of successful downstaging (p < 0.023 and p < 0.049 respectively). Biological characteristics of HCC as AFP levels <100 ng/mL and high 3-year calculated survival probability may predict a good response to downstage after IAT.

    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.

    Full Text Available Improved survival from congenital heart disease has led to an increasing need for complex reoperation by reentrant sternotomy. Peripheral cannulation and initiation of cardiopulmonary bypass prior to sternotomy to avoid the risk of cardiac injury and massive hemorrhage is an option in adults and larger children, but femoral vessel size precludes this strategy in infants. We describe the management of a high-risk reentry sternotomy in an infant for repair of a giant pseudoaneurysm after prior homograft repair of tetralogy of Fallot, using surgical dissection for suprasternal cannulation of the innominate artery and subxyphoid cannulation of the inferior vena cava.

    To investigate the clinical efficacy of individual endovascular management for the treatment of different traumatic pseudo aneurysms presenting as intractable epistaxis. For 14 consecutive patients with traumatic pseudo aneurysm presenting as refractory epistaxis, 15 endovascular procedures were performed. Digital subtraction angiography revealed that the pseudo aneurysms 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 (Inca); out of which, two were managed with detachable balloons, two with covered s tents, 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. Complete cessation of bleeding was achieved in all the 15 instances (100%) immediately after the endovascular therapies. Of the six patients who suffered from Inca pseudo aneurysms, one presented with a permanent stroke and one had an episode of rebleeding requiring intervention. In patients presenting with a history of cranio cerebral trauma, traumatic pseudo aneurysm must be considered as a differential diagnosis. Individual endovascular treatment is a relatively safe, plausible, and reliable means of managing traumatic pseudo aneurysms

    2001-01-01

    Objective: To evaluate the effectiveness, toxicity and prospective application of hepatic arterial infusion (HAI) with embolized Curcuma Aromatic oil (CAO) in treating primary liver cancer (PLC). Methods: In the treated group, 32 patients with PLC were treated by HAI with 1-3 ml embolized CAO and oral administration of Chinese herbal medicine. In the control group, 32 patients with PLC were treated with transcatheter artery chemoembolization (TACE). Results: In the treated group, one patient attained complete remission (CR) and 13 partial remission (PR), the total effective rate being 43.75%. The level of alpha fetal protein (AFP) turned to normal range in 7 cases and decreased in other 7. In the control group, 10 obtained PR and the total effective rate being 31.25%, AFP level turned to normal in 5 and decreased in 2. There was no statistical significance between the two groups. The incidences of post-embolism Sydrome, such as fever, abdominal pain and vomiting were similar between the two groups but no myelosuppression occurred in the treated group with significant difference as comparing with that in the control group (P<0.01). The mean survival time, median survival time, 1-, 2- and 3-year survival rate in the treated group were 11.5 months, 10 months, 37.5%, 13.3% and 6.9% respectively, while in the control group they were 7.25 months, 6 months, 15.6%, 3.2% and 0% respectively. Better result in mean survival time, median survival time and 1-year survival rate was found in the treated group than that of the control group (P<0.05). Conclusion:HAI with embolized CAO showed a similar good effect in treating PLC as that of TACE, but superior to TACE with longer survival time and milder myelosuppression.

    Imaging the pregnant patient presents a unique challenge to radiologist due to the risk of radiation to the conceptus (embryo/fetus). A rare case of a successfully recognized and treated pseudoaneurysm (PA) of the abdominal aorta is to be presented. The pseudoaneurysm occurred in the third trimester and had a favorable outcome for the mother and the baby. Emergent abdominal ultrasound (US) is the first modality in diagnostic algorithm for the rupture of aortic aneurysm in a pregnant woman. It provides the most rapid diagnostic information, although intestinal gas and abdominal tenderness may limit its accuracy. To confirm the findings, magnetic resonance angiography (MRA) or CT angiography (CTA) can be used. In our case, the diagnosis was established using a color Doppler ultrasonography of the abdomen and was later confirmed by a low dose CT scan of the abdominal aorta. MRA in such cases have some disadvantages. At many health centers, the monitoring of patients with acute ruptures is more difficult in the MR suite than at the CT scanner. MRA angiographic images are also subject to degradation by multiple artifacts and the visualization of the distal vasculature is suboptimal and inferior to the one done by CTA. Due to fetal movements, a small quantity of fresh blood can be overlooked by MR. MRA is often not available on a 24-hours basis, and the time required for making a diagnosis can preclude the use of MRA in an unstable patient. For this reason, we used a low dose CTA protocol to confirm the diagnosis. Low dose scanning protocols in CT can obtain sufficient diagnostic information while reducing the risk of radiation. A particular focus is put on the outline of new concepts for dose management and optimization. We used new approaches based on tube current modulation. The birth was induced by an urgent Caesarean section followed by a resection of a pseudoaneurysm and a reconstruction of the aorta with an end-to-end vascular prosthesis. PMID:26898082

    There are a wide variety of coronary artery anomalies and disease in adults with congenital heart disease (CHD). In fact, the increasing burden of acquired coronary artery disease (CAD) has to be considered in addition to congenital abnormalities of the coronary arteries, isolated or associated to other congenital diseases. This is largely a consequence of the increasing number of patients reaching older age. Due to complex underlying cardiac anatomy, previous surgery and comorbidities, treatment can be challenging. Individualized and multidisciplinary management involving congenital heart cardiologists, cardiac surgeons, coronary interventionists and imaging specialists is essential. This review gives an overview of coronary artery involvement in adults with CHD, summarizes the current literature and focuses on prevention, diagnosis and treatment. The potential role of cardiovascular risk factors for CAD is also discussed.

    Hyperbaric oxygen therapy is the primary treatment for arterial gas embolism, decompression sickness and acute carbon monoxide poisoning. Though there has been a proliferation of hyperbaric centers throughout the United States, a scarcity of centers equipped to treat emergency indications makes transport of patients necessary. To locate and characterize hyperbaric chambers capable of treating emergency cases, a survey of centers throughout the entire United States was conducted. Using Google, Yahoo, HyperbaricLink and the UHMS directory, a database for United States chambers was created. Four researchers called clinicians from the database to administer the survey. All centers were contacted for response until four calls went unreturned or a center declined to be included. The survey assessed chamber readiness to respond to high-acuity patients, including staff availability, use of medical equipment such as ventilators and intravenous infusion devices, and responding yes to treating hyperbaric emergencies within a 12-month period. Only 43 (11.9%, N = 361) centers had equipment, intravenous infusion pumps and ventilators, and staff necessary to treat high-acuity patients. Considering that a primary purpose of hyperbaric oxygen therapy is the treatment of arterial gas embolism and decompression sickness, more hyperbaric centers nationwide should be able to accommodate these emergency cases quickly and safely.

    Full Text Available Traumatic coronary artery dissection is an uncommon cause of acute myocardial infarction (AMI. We report a case of blunt chest trauma resulting from a motorcycle collision causing ostial dissection of the left anterior descending (LAD artery in a 31-year-old previously healthy male. The patient also suffered from compound comminuted fractures of the humerus and ulna and severe liver laceration, which hampered both percutaneous and surgical acute revasularization. After a stormy hospital course, a bare metal stent was implanted to seal the LAD artery dissection. The patient was discharged in a stable condition and was followed-up for rehabilitation. This case report underscores the multidisciplinary approach in facing challenges encountered after rare sequelae of chest trauma.

    Full Text Available Abstract Background The ergotamine tartrate associated with certain categories of drugs can lead to critical ischemia of the extremities. Discontinuation of taking ergotamine is usually sufficient for the total regression of ischemia, but in some cases it could be necessary thrombolytic and anticoagulant therapy to avoid amputation. Case report A woman of 62 years presented with a severe pain left forearm appeared 10 days ago, with a worsening trend. The same symptoms appeared after 5 days also in the right forearm. Physical examination showed the right arm slightly hypothermic, with radial reduced pulse in presence of reduced sensitivity. The left arm was frankly hypothermic, pulse less on radial and with an ulnar humeral reduced pulse, associated to a decreased sensitivity and motility. Clinical history shows a chronic headache for which the patient took a daily basis for years Cafergot suppository (equivalent to 3.2 mg of ergotamine. From about ten days had begun therapy with itraconazole for vaginal candidiasis. The Color-Doppler ultrasound shown arterial thrombosis of the upper limbs (humeral and radial bilateral, with minimal residual flow to the right and no signal on the humeral and radial left artery.

    Two cases of left ventricular pseudoaneurysm following myocardial infarction are presented. In the first patient a two-dimensional echocardiography study revealed a small posterior echo-free space that appeared to communicate with the left ventricle through a small defect in the left ventricular posterior wall. Conventional Doppler echocardiography and colour flow imaging demonstrated flow between the left ventricle and the paraventricular chamber. In the other patient, the same study detected an enormous false aneurysm. We found a large extramyocardial echo-free space within the pericardial cavity. The site of this space was posterolateral and communicating with the left ventricular cavity. Cardiac catheterization and surgery confirmed the diagnosis. A postoperative echocardiographic study demonstrated a persistent but smaller saccular echo-free space and a residual shunt through one site of repair in the first patient; in the other, after surgical treatment there was no residual flow, but a left ventricular dysfunction was detected. Two dimensional and color Doppler echocardiography is the best technique among the noninvasive methods, for detecting and following up left ventricular pseudoaneurysms. PMID:8325466

    2014-01-01

    Full Text Available Pseudoaneurysm of mitral-aortic intervalvular fibrosa (P-MAIVF is a rare cardiac surgical condition. P-MAIVF commonly occurs as a complication of aortic and mitral valve replacement surgeries. The surgical trauma during replacement of the valves weakens the avascular mitral and aortic intervalvular area. We present a case of P-MAIVF recurrence 5 years after a primary repair. Congestive cardiac failure was the presenting feature with mitral and aortic regurgitation. In view of the recurrence, the surgical team planned for a double valve replacement. The sewing rings of the two prosthetic-valves were interposed to close the mouth of the pseudoaneurysm and to provide mechanical reinforcement of the MAIVF. Intra-operative transesophageal echocardiography (TEE helped in delineating the anatomy, extent of the lesion, rupture of one of the pseudoaneurysm into left atrium and severity of the valvular regurgitation. Post-procedure TEE confirmed complete obliteration of the pseudoaneurysm and prosthetic valve function.

    Background. To investigate the safety and efficacy of superselective transcatheter arterial embolization (TAE) with n-butyl cyanoacrylate (NBCA) in treating lower gastrointestinal bleeding caused by angiodysplasia. Methods. A retrospective study was performed to evaluate the clinical data of the patients with lower gastrointestinal bleeding caused by angiodysplasia. The patients were treated with superselective TAE with NBCA between September 2013 and March 2015. Angiography was performed after the embolization. The clinical signs including melena, anemia, and blood transfusion treatment were evaluated. The complications including abdominal pain and intestinal ischemia necrosis were recorded. The patients were followed up to evaluate the efficacy in the long run. Results. Seven cases (2 males, 5 females; age of 69.55 ± 2.25) were evaluated in the study. The embolization was successfully performed in all cases. About 0.2–0.8 mL (mean 0.48 ± 0.19 mL) NCBA was used. Immediate angiography after the embolization operation showed that the abnormal symptoms disappeared. The patients were followed up for a range of 2–19 months and six patients did not reoccur. No serious complications, such as femoral artery puncture point anomaly, vascular injury, and intestinal necrosis perforation were observed. Conclusion. For the patients with refractory and repeated lower gastrointestinal hemorrhage due to angiodysplasia, superselective TAE with NBCA seem to be a safe and effective alternative therapy when endoscopy examination and treatment do not work.

    Vascular access for hemodialysis remains a challenge for nephrologists, vascular surgeons, and interventional radiologists alike. Arteriovenous fistula and synthetic grafts remain the access of choice for long-term hemodialysis; however, they are subject to complications from infection and repeated needle cannulation. Pseudoaneurysms are an increasingly recognized adverse event. At present, there are many minimally invasive methods to repair these wall defects. We present a graft pseudoaneurysm, which required a combination of endovascular stent graft placement and percutaneous thrombin injection for successful occlusion.

Methods From April 2007 to November 2010,20 patients of descending aortic pseudoaneurysm were treated.There were 18 male and 2 female,aged from 28 to 82 years with a mean of (58 ± 16) years.In this group,4 patients were diagnosed as Behcet's syndrome,6 patients as mycotic pseudoaneurysms with positive blood culture,6 patients as suspected mycotic pseudoaneurysms,1 patient with iatrogenic pseudoaneurysm and 1 patient with chronic grain-mononuclear cell leukemia,the other 3 patients with unknown reasons.The 88.5% of aortic pseudoaneurysms were located at abdominal aorta.Fifteen patients underwent endovascular therapy and 2 patients were treated by traditional open surgery.The other 3 patients underwent conservative treatments.The data of treatments and follow-up in the 15 patients who received endovascular repairs were retrospectively analyzed. Results Endovascular therapy was performed successfully on the 15 patients,and the technique successful rate was 15/15.Total 15 stents were transluminal placed including 6 bifurcate stent-grafts,6 abdominal straight stent-grafts,2 thoracic straight stent-grafts and 1 abdominal bare stent.One patient was treated by stent assisted embolization.Perioperative mortality rate was 0.Only 2 primary type Ⅳ endoleaks were found.Fourteen patients were successfully followed up.During a mean follow-up of 538 days,8(57.1% ) patients were uneventful.Six (42.9%) patients were complicated by aneurysm related events,including 4 (28.6%) aneurysm-related deaths,1(7.14%) with delayed endoleak and 1 (7.14% ) with recurrent pseudoaneurysm which was retreated by another stent-graft.Conclusions Endovascular therapy for descending aortic pseudoaneurysms is a feasible and mini-invasive option with high technique success rate and low perioperative mortality rate.However,risk of recurrence and rupture to death of

    The development of a pseudoaneurysm is a rare complication following repair of a coarctation of the aorta. Surgical management of pseudoaneurysms is associated with high morbidity and mortality. We describe the successful endovascular deployment of a covered stent in a sick infant with a descending aorta pseudoaneurysm, following the repair of an aortic coarctation. We highlight the challenges we encountered. Endovascular repair is a safe palliative alternative to re-do open surgery in unstable infants with large pseudoaneurysms following aortic coarctation repair. The role of endovascular stents as the final definitive therapy will remain limited by the deployable, small-size stents in small, growing children.

    Full Text Available Objective. To validate the empiric observation that pH has an important effect on oxygenation in infants receiving iNO. Study Design. Demographics, ventilator settings, arterial blood gases (ABG, and interventions for up to 96 hours of life were extracted from the charts of 51 infants receiving iNO. Need for ECMO and survival to discharge were noted. Mean blood pressure (MBP and mean airway pressure (MAP were recorded. The arterial/alveolar (a/A ratio was used as the primary outcome. Analysis was by simple linear regression and multiple linear regression analyses and Fisher's exact test. pH responsiveness was arbitrarily defined as a correlation coefficient (CC of >0.40 with 7.55. Of 11 patients requiring ECMO, only 3 exhibited responsiveness at any time in their course. Three responders required ECMO. Conclusion. This small study suggests that failure or inability to optimize pH may account for observed unresponsiveness to iNO. Maintaining a pH > 7.5 using hyperventilation is not recommended.

    An 81-year-old male with previous open abdominal aortic aneurysm repair presented with asymptomatic large pseudoaneurysms at both ends of an open surgical tube graft. Endovascular aneurysm sealing (EVAS) in combination with the iliac limbs of a standard endovascular aneurysm repair (EVAR) successfully excluded both pseudoaneurysms from circulation. We describe the combination of elements of EVAS and EVAR and have termed this endovascular aneurysm repair and sealing (EVARS). EVARS has the advantage of harnessing the benefits of endobag sealing in aortic necks unsuitable for standard EVAR whilst providing the security of accurate stent placement within short common iliac arteries. In conclusion, EVAS may be combined with standard endovascular iliac limbs and is a possible treatment option for pseudoaneurysm following open aneurysm repair. PMID:26493819

    PurposeThis study was designed to assess the efficacy and safety of the ExoSeal vascular closure device (VCD) to achieve hemostasis in antegrade access of the superficial femoral artery (SFA).MethodsWe retrospectively reviewed the outcome of ExoSeal VCD used for hemostasis in 110 accesses to the SFA in 93 patients between July 2011 and July 2013. All patients had patent proximal SFA based on computer tomography angiography or ultrasound duplex. Arterial calcifications at puncture site were graded using fluoroscopy. The SFA was accessed in an antegrade fashion with ultrasound or fluoroscopic guidance. In all patients, 5–7F vascular sheaths were used. The ExoSeal VCD was applied to achieve hemostasis at the end of the procedure. All patients were clinically examined and had ultrasound duplex exam for any puncture site complications during the 24 h postprocedure.ResultsIn all procedures, the ExoSeal was applied successfully. We did not encounter any device-related technical failure. There were four major complications in four patients (3.6 %): three pseudoaneurysms, which were treated with direct thrombin injection, and one hematoma, which necessitated transfusion of two blood units. All patients with complications were treated with anticoagulation preprocedure or received thrombolytic therapy.ConclusionsThe ExoSeal VCD can be safely used for antegrade puncture of the SFA, with a high procedural success rate (100 %) and a low rate of access site complications (3.6 %)

    Heparin-induced thrombocytopaenia is a dreaded, although infrequent, complication of heparin therapy. We report two cases of heparin-induced thrombocytopaenia (HIT) type II occurring in a patient treated with standard (unfractionated) heparin and in another patient given a low-weight molecular heparin. The clinical course of the first patient illustrates the potentially severe thrombotic complications of HIT. Both cases were treated successfully by danaparoid sodium. Clues to the diagnosis and treatment are briefly discussed. PMID:10981327

    Purpose: To investigate the percutaneous endovascular management of visceral aneurysms (VA) and visceral pseudoaneurysms (VPA) treated in three European interventional radiology departments. Methods: Patient archives from the department's databases were examined and retrospectively analyzed. Patients diagnosed between 2000 and 2010 with VA and/or VPA, confirmed by computed tomography angiography, magnetic resonance angiography, or digital subtraction angiography and treated exclusively with percutaneous endovascular methods, were included in the study. The study's primary end points were procedural technical success, target lesion reintervention rate, and periprocedural mortality rate. Secondary end points included major and minor complications rates. Results: The medical records of 54 patients (41 male, mean age 55 {+-} 18.1 years) with 58 VAs or VPAs and treated with various percutaneous endovascular therapeutic modalities were analyzed. In total, 21 VAs (mean diameter 49.4 {+-} 21 mm, range 20-100 mm) and 37 VPAs (mean diameter 25.1 {+-} 14.6 mm, range 8-60 mm) were treated. Procedural technical success was achieved in 100% of the cases, while target lesion reintervention rate was 6.1% (2 of 33) and 14.2% (3 of 21) in the VPA and VA groups, respectively. Mean clinical follow-up period was 19.1 {+-} 21.4 months. Overall periprocedural mortality rate was 3% (1 of 33) in the VPA group and 0% (0 of 21) in the VA group. Conclusion: Percutaneous endovascular treatment of VAs and VPAs is safe and effective with low morbidity and mortality. There is a small but significant reintervention rate, particularly for true aneurysms; dedicated follow-up imaging is recommended. Successful aneurysm exclusion was achieved in all cases with a second procedure.

    Mycobacterium kansasii is a photochromogenic, slow-growing mycobacterium species that can cause pulmonary infection in patients with predisposing lung diseases, as well as extrapulmonary or disseminated disease in immunosuppressed patients. We describe a patient with a myelodysplastic syndrome, disseminated M kansasii infection, and ruptured aortic aneurysm. He had a recent diagnosis of mycobacterium cavitary lung lesions and was transferred to our facility for possible surgical intervention of an aortic aneurysm. Few hours after admission, the patient suddenly collapsed and died despite resuscitation efforts. A complete autopsy was performed and showed ruptured ascending aortic pseudoaneurysm with hemopericardium, disseminated necrotizing and nonnecrotizing granulomas with acid-fast bacilli in the aortic wall, lungs, heart, liver, spleen, and kidneys. Further genetic studies were consistent with monocytopenia and mycobacterial infection syndrome. PMID:25537975

    Full Text Available Abstract We present a case of 58-year-old woman with underlying diabetes mellitus, hepatitis C virus-related liver cirrhosis, and total hysterectomy for uterine myoma 11 moths ago, who was diagnosed ruptured aortic arch mycotic pseudoaneurysm after a certain period of survey for her unknown fever cause. After emergent surgery with prosthetic graft interposition, all her blood cultures and tissue cultures revealed pathogen with Bacteroides fragilis. Although mycotic aneurysms have been well described in literatures, an aneurysm infected solely with Bacteroides fragilis is unusual, with only eight similar cases in the literature. Here we reported the only female case with her specific clinical and management course and summarized all reported cases of mycotic aneurysm caused by Bacteroides fragilis to clarify their conditions and treatments, alert the difficulty in diagnosis, and importance of highly suspicious.

    Full Text Available We report a 50-year-old male patient with diabetes mellitus and hypertension who presented with low-grade fever, anuria and renal failure. He had no prior history of nephropathy and retinopathy. Since anuria persisted, a renal biopsy was performed using automated gun, under ultrasound guidance. Two hours after the renal biopsy was performed, the patient developed severe left loin pain that required analgesics and sedatives. Ultrasound of the abdomen performed immediately, two hours and four hours after the biopsy, did not reveal any hematoma. The hemoglobin was stable when the patient developed loin pain, but after eight hours decreased to 9.1 g/dL, and computed tomography scan of the abdomen revealed a big peri-nephric hematoma around the left kidney. He was managed with blood transfusions and a selective angiogram was done. It revealed a pseudoaneurysm and arterio-venous fistula from the segmental artery of lower pole of the left kidney; both were closed by using microcoils and liquid embolic agent N-butyl-cyanoacrylate (NBCA. The only risk factor the patient had at the time of renal biopsy was severe renal failure. Our case suggests that severe loin pain immediately after renal biopsy in a patient with renal failure warrants careful follow-up of hemoglobin and imaging, even if initial imaging is normal. Further fall of hemoglobin necessitates early evaluation with angiogram, which helps in diagnosing the treatable, although rare, complications like pseudoaneurysm and arterio-venous fistula.

  15. The use of routine imaging data in diagnosis of cerebral pseudoaneurysm prior to angiography

    International Nuclear Information System (INIS)

    Purpose: A false aneurysm is rare and underdiagnosed complication of intracranial hemorrhage. Objective of the study was to point out diagnostic imaging signs of false aneurysm and to determine frequency and diagnostic significance of these signs. Materials and methods: Cerebral arteriography performed in our center from November 2007 to September 2010 revealed the false aneurysm in 8 patients (4 male, 4 female, mean age was 38 years). During the same angiographic procedure 6 patients were treated by endovascular embolization using coils, mixture of Histoacryl and Lipiodol or Onyx (liquid embolic material). Authors retrospectively analyzed preprocedural studies (computed tomography, magnetic resonance imaging) and angiographic findings to identify signs specific to false aneurysm. Results: Computed tomographic findings that are not specific but should raise suspicion of the false aneurysm include: enlargement of parenchymal hematoma dimensions, unusual or delayed evolution of hematoma and spot sign associated with acute hematoma expansion. More specific signs can be revealed in digital subtraction angiography that shows a globular shaped neckless aneurysmal sac, delayed filling and emptying of contrast agent and stagnation of contrast with regard to the head position. Conclusion: Although preangiographic imaging studies findings in patients with false aneurysms are not specific, they should lead to angiographic validation, especially enlarging parenchymal hematoma and atypical hematoma evolution. Digital subtraction angiography makes it possible to diagnose the lesion and to use endovascular embolization techniques, which are currently the method of choice for treatment of pseudoaneurysms.

  17. Adolescent External Iliac Artery Trauma: Recurrent Aneurysmal Dilatation of an Iliofemoral Saphenous Vein Graft Treated by Stent-Grafting

    International Nuclear Information System (INIS)

    An adolescent male sustained a severe penetrating injury to the external iliac artery. Emergency surgical revascularization was with a reversed long saphenous vein interposition graft. The primary graft and the subsequent revision graft both became aneurysmal. The second graft aneurysm was successfully excluded by endovascular stent-grafts with medium-term primary patency. A venous graft was used initially rather than a synthetic graft to reduce the risk of infection and the potential problems from future growth. Aneurysmal dilatation of venous grafts in children and adolescents is a rare but recognized complication. To the best of our knowledge, exclusion of these aneurysms with stent-grafts has not been previously reported in the adolescent population.

    Background: There are very few reports regarding the use of 3D rotational angiography (3D RA) in embolization of renal artery aneurysms (RAAs). No valuable data have been reported on the follow-up result of coil embolization for RAAs on computed tomography (CT). Purpose: To evaluate the clinical and multidetector computed tomography (MDCT) follow-up results of renal artery aneurysms treated by detachable coil embolization using 3D RA. Material and Methods: Six patients diagnosed with RAAs were included. Five patients underwent detachable coil embolization. Five patients underwent 3D RA and the parameters used for planning endovascular treatment obtained by 2D CT, reformatted 3D CT angiography (3D CTA), 2D digital subtraction angiography (2D DSA) and 3D RA were compared. The post embolization MDCT follow-up findings were analyzed retrospectively. Results: The technical success rate for detachable coil embolization was 40%. The 3D CTA showed the dome-to-neck ratio (DNR) and tangential view of the renal artery aneurysm in five patients (83.3%) and the 2D CT showed it in four (66.7%). An optimal working angle assessment could not be obtained on the 2D CT and 3D CTA. The 3D RA showed the DNR, tangential view, and optimal working angle in all patients. Renal infarction occurred in three patients and Postprocedural hypertension developed in two patients during the follow-up period. Conclusion: The 3D RA was useful in preoperative determination of adequate working angle for detachable coil embolization of RAAs. Late complications of detachable coil embolization for RAAs were renal infarction and hypertension

    Full Text Available Abstract Background Congenital heart defect (CHD account for 25% of all human congenital abnormalities. However, very few CHD-causing genes have been identified so far. A promising approach for the identification of essential cardiac regulators whose mutations may be linked to human CHD, is the molecular and genetic analysis of heart development. With the use of a triple retinoic acid competitive antagonist (BMS189453 we previously developed a mouse model of congenital heart defects (81%, thymic abnormalities (98% and neural tube defects (20%. D-TGA (D-transposition of great arteries was the most prevalent cardiac defect observed (61%. Recently we were able to partially rescue this abnormal phenotype (CHD were reduced to 64.8%, p = 0.05, by oral administration of folic acid (FA. Now we have performed a microarray analysis in our mouse models to discover genes/transcripts potentially implicated in the pathogenesis of this CHD. Results We analysed mouse embryos (8.5 dpc treated with BMS189453 alone and with BMS189453 plus folic acid (FA by microarray and qRT-PCR. By selecting a fold change (FC ≥ ± 1.5, we detected 447 genes that were differentially expressed in BMS-treated embryos vs. untreated control embryos, while 239 genes were differentially expressed in BMS-treated embryos whose mothers had also received FA supplementation vs. BMS-treated embryos. On the basis of microarray and qRT-PCR results, we further analysed the Hif1α gene. In fact Hif1α is down-regulated in BMS-treated embryos vs. untreated controls (FCmicro = -1.79; FCqRT-PCR = -1.76; p = 0.005 and its expression level is increased in BMS+FA-treated embryos compared to BMS-treated embryos (FCmicro = +1.17; FCqRT-PCR = +1.28: p = 0.005. Immunofluorescence experiments confirmed the under-expression of Hif1α protein in BMS-treated embryos compared to untreated and BMS+FA-treated embryos and, moreover, we demonstrated that at 8.5 dpc, Hif1α is mainly expressed in the embryo heart

    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.

  3. Therapeutic strategy for pseudoaneurysma: a report of 21 cases

    International Nuclear Information System (INIS)

    Objective: To study the locations, types and causes of different pseudoaneurysms in order to find out the optimal individualized treatment for different pseudoaneurysms. Methods: Different methods were applied in treating 21 patients with pseudoaneurysm, which were located at limb (n=11), spleen (n= 3), kidney (n=2), common iliac artery (n=1), internal iliac artery (n=1), gallbladder (n=1) and penis (n=1). Different managements were employed in treating these pseudoaneurysms. Temporary obstruction of blood circulation with balloon together with arterial anastomosis or direct incision neoplasty was performed in 9 cases with pseudoaneurysms at limb arteries close to the larger joints. Endovascular stent graft was used to isolate the trunk type of pseudoaneurysm in 4 cases, in 2 of them branch arterial embolism and stent graft endovascular exclusion were applied as they had common iliac artery trunk type of pseudoaneurysm at the opening of internal iliac artery. Gelfoam together with metallic coils embolization was employed in 6 cases with terminal type of pseudoaneurysms. Results: After different treatments, tumor cavities disappeared in the 21 cases with pseudoaneurysms. Distal arterial pulse returned to normal and no nerve damage occurred in 11 cases with limb pseudoaneurysms. No internal hemorrhage was observed and distal blood circulation returned to normal after graft endovascular exclusion in 2 cases with pseudoaneurysms at spleen artery trunk and in 2 cases with pseudoaneurysms at iliac artery trunk. In 6 cases with terminal type of pseudoaneurysms, the tumor cavity disappeared, hemorrhage stopped and no ischemic necrosis of organ occurred. But one of them with multiple traumatic pseudoaneurysms located at the second grade branch died one week after embolism due to a serious pelvic trauma accompanied with serious infection. Conclusion: Based on the locations, types and causes of pseudoaneurysms, different individualized treatment should be adopted in order to

    Background Though drug-eluting stent (DES) almost solved a problem of restenosis,safety issues related to stent thrombosis are still the major concern of DES.We hypothesized that hybrid stent implantation may decrease the use of DES,probably improving the long-term safety but not affecting efficacy adversely when treating multilesion coronary artery disease in the DES era.Methods From April 2004 to October 2006,848 patients with multilesion disease underwent hybrid stent implantation.During the same period 5647 patients with multilesion coronary heart disease were treated by exclusive DES implantation in Fu Wai Hospital.According to propensity score matching,we chose 823 pairs of patients with multileison coronary artery disease for inclusion into our study.We obtained the 24-month clinical outcome including death,myocardial infarction (MI),thrombosis,target lesion revascularization (TLR),target vessel revascularization (TVR),and major adverse cardiac events (MACE,the composite of death,MI,and TVR).We used Cox's proportional-hazard models to assess relative risks of all the outcome measures after propensity match.Results At 24 months,patients in the hybrid stent implantation group showed a significantly higher risk of TLR (8.39%vs.3.28%,HR2.38,95% CI:1.50-3.70),TVR (11.07% vs.6.32%,HR 1.61,95% CI:1.15-2.27) and MACE (13.75% vs.8.75%,HR 1.37,95% CI:1.02-1.85).No significant difference was apparent in terms of mortality (1.22% vs.1.70%,HR 0.55,95% CI:0.24-1.25),MI (1.95% vs.2.31%,HR0.73,95% CI:0.37-1.42),or thrombosis (definite+probable) (0.73% vs.1.58%,HR0.40,95% CI:0.15-1.05).Conclusions In patients with multilesion coronary artery disease,the exclusive DES implantation was associated with significantly lower risks of TLR,TVR and MACE,and the hybrid stent implantation did not result in any significant improvements regarding safety issues.Prospective studies are needed to confirm our results.

    Full Text Available Objective To evaluate the practical value of transthoracic echocardiography (TTE in transcatheter treatment in patients with patent ductus arterious (PDA living in regions of different altitude. Methods Three hundred and fifty-three patients with PDA who had undergone TTE examination were divided into two groups, 115 patients in high altitude group (living in regions higher than 3600m and 238 patients in low altitude group (living in regions lower than 800m. The pattern, diameter and length of PDA were determined by TTE (Vivid 7, and the therapeutic effect was assessed 3~5 days, and 3, 6 and 12 months after closure. Results Thirty patients were found to have other congenital heart diseases. Transcatheter closure was successful in 346 patients, and the success rate of operation was 98.0%. Compared with that before operation, the left ventricular diameter and left ventricular ejection fraction (LVEF were decreased significantly after closure (P<0.05. The LVEF in 19 patients was decreased to less than 50%, including 14 patients living in high altitude regions and 5 patients living in low altitude regions. Of 36 patients whose systolic pulmonary pressure was over 70mmHg, 32 underwent closure successfully and their systolic pulmonary pressure decreased more than 30mmHg after operation. Residual shunt was found in 13 patients. Out of these patients, the occluder was removed in 1 by surgery, and the residual shunt disappeared in 7 patients 3 months later. The occluders in 12 patients were larger than 50% of the diameter of descending aorta. Increased flow rate in the descending aorta was found in one of the 12 patients. Conclusion  Echocardiography is a valuable method in screening the PDA patients living in regions of different altitude before transcatheter therapy, and also for evaluating the therapeutic effects after the operation.

    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.

    Endoscopic hemostasis is a useful treatment modality for gastric ulcer bleeding. However, it is sometimes difficult to achieve hemostasis in cases with arterial bleeding, especially those complicated with vascular abnormalities. We describe a case with gastric ulcer bleeding from a variant left gastric artery accompanied by congenital absence of the splenic artery. A 50-year-old female was admitted to our hospital with dizziness and tarry stools. Upper gastrointestinal endoscopy revealed bleeding from a gastric ulcer, and endoscopic hemostasis by endoscopic clipping was carried out. Computed tomography and abdominal angiography revealed the variant left gastric artery running below the gastric ulcer. In spite of endoscopic hemostasis and medication, re-bleeding from the gastric ulcer occurred. A transcatheter coil embolization for the variant left gastric artery was performed and successfully achieved hemostasis. This case was accompanied by congenital absence of the splenic artery, which is an extremely rare condition. We herein describe this rare case and review previously reported cases.

  10. Endoluminal Repair of a Dardik Prosthesis Pseudoaneurysm Using the Wallgraft Endoprosthesis

    International Nuclear Information System (INIS)

    A 58-year-old man with a history of severe invalidating claudicatio intermittens underwent femoropopliteal bypass with a human umbilical vein graft. Seven years later he presented with a painful enlarging mass in the middle portion of his right thigh. The duplex scan showed a pseudoaneurysm of the body of the prosthesis, which was confirmed by angiography. As an alternative to surgical management, Wallgraft endoprosthesis was used for endoluminal exclusion of the pseudoaneurysm. To our knowledge, this technique has never been used before in such a case

    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.

    Failing to reach blood pressure (BP) goals is one of the main problems in hypertension management. Especially in high-risk patients, intensive monitoring including frequently office visits or new techniques to monitor home BP is required. A total of 60 patients with uncontrolled hypertension were included and randomized into a group with telemetric BP monitoring (TBPM) (n=30) and a control group receiving standard care (n=30). During the 3-month study period, patients received in addition to their antihypertensive pre-treatment up to 2 × 300 mg irbesartan to achieve the required target BP. All patients were instructed to measure their BP once daily in the morning. In the TBPM group automatic alerts were generated by the central database server using pre-defined algorithms and patients were subsequently contacted by the physician. At baseline mean 24-h ambulant BP monitoring (ABPM) was 143.3±11.1/82.6±9.9 mm Hg in the TBPM group and 141.4±12.6/82.1±6.5 mm Hg in the standard care group. During treatment mean systolic BP showed a more intensive decrease in the TBPM vs control group (-17.0±11.1 mm Hg vs -9.8±13.7 mm Hg; P=0.032). Patients in the TBPM group had a more pronounced night dipping and a higher reduction of mean pulse pressure than controls (-8.1±5.9 mm Hg vs -2.8±7.4 mm Hg, P=0.004). After 3 months, TBPM-treated patients were given a higher mean daily dose of irbesartan (375±187 mg vs 222±147 mg in controls; P=titration of the antihypertensive agent is possible. The alarm criteria chosen were useful to improve BP control. PMID:21228822

    Full Text Available Um estudante de 17 anos, masculino, sofreu ferimentos por arma de fogo e foi submetido a uma laparotomia exploradora. No pós-operatório, queixava-se de dores em membros inferiores e de massa abdominal pulsátil. Realizou tomografia computadorizada (TC de abdome, que evidenciou pseudoaneurisma de aorta abdominal de cerca de 8 cm no maior diâmetro, localizado entre o tronco celíaco e a artéria mesentérica superior. Uma arteriografia confirmou o diagnóstico e procedeu-se, então, a embolização da lesão com fragmentos de fio-guia montados com fios de algodão. Após seis meses, realizou ecoDoppler de aorta abdominal e nova TC de abdome, que evidenciaram fluxo no interior do saco do pseudoaneurisma. Foi, então, submetido a nova embolização endovascular e implante de stent não-revestido de 18 x 58 mm. Após seis meses do último procedimento, realizou-se nova TC de abdome que demonstrou exclusão da lesão.A 17 years old male student has received several gunshots and was submitted to exploratory laparotomy. After surgery, he complained of pain in the lower limbs and a pulsatile abdominal mass. An abdominal computerized tomography (CT scan was carried out and revealed an abdominal aorta pseudoaneurysm of about 8 cm in the larger diameter between the celiac trunk and the superior mesenteric artery. An arteriography confirmed the diagnosis and he was submitted to the lesion embolization with cotton suture wires attached to metallic guide wire fragments. After six months, an abdominal aorta Doppler ultrasonography and a new abdominal CT scan were ordered and depicted flow inside the pseudoaneurysm. The patient was then submitted to a new endovascular embolization, and an 18 x 58 mm uncovered stent was placed. After six months from the last procedure, a new abdominal CT scan showed exclusion of the lesion.

  15. The normal distribution of thoracoabdominal aorta small branch artery ostia

    International Nuclear Information System (INIS)

    The purpose of this study was to determine the normal distribution of aortic branch artery ostia. CT scans of 100 subjects were retrospectively reviewed. The angular distributions of the aorta with respect to the center of the T3 to L4 vertebral bodies, and of branch artery origins with respect to the center of the aorta were measured. At each vertebral body level the distribution of intercostal/lumbar arteries and other branch arteries were calculated. The proximal descending aorta is posteriorly placed becoming a midline structure, at the thoracolumbar junction, and remains anterior to the vertebral bodies within the abdomen. The intercostal and lumbar artery ostia have a distinct distribution. At each vertebral level from T3 caudally, one intercostal artery originates from the posterior wall of the aorta throughout the thoracic aorta, while the other intercostal artery originates from the medial wall of the descending thoracic aorta high in the chest, posteromedially from the mid-thoracic aorta, and from the posterior wall of the aorta low in the chest. Mediastinal branches of the thoracic aorta originate from the medial and anterior wall. Lumbar branches originate only from the posterior wall of the abdominal aorta. Aortic branch artery origins arise with a bimodal distribution and have a characteristic location. Mediastinal branches of the thoracic aorta originate from the medial and anterior wall. Knowing the location of aortic branch artery ostia may help distinguish branch artery pseudoaneurysms from penetrating ulcers.

    Full Text Available Sildenafil and bosentan are increasingly used for the treatment of pulmonary arterial hypertension (PAH in HIV-infected patients. However, concerns exist about pharmacokinetic interactions among sildenafil, bosentan and antiretroviral drugs, including protease inhibitors (PI. We describe here the case of an HIV-infected patient with PAH, who was co-administered bosentan 125 mg twice daily and sildenafil 40 mg three times per day, together with a ritonavir-boosted PI-based antiretroviral therapy; plasma levels of bosentan, sildenafil, N-desmethylsildenafil, and PI were measured. The patient had a sildenafil Cthrough and Cmax of 276.94 ng/mL and 1733.19 ng/mL, respectively. The Cthrough and the Cmax of bosentan were 1546.53 ng/mL and 3365.99 ng/mL, respectively. The patient was able to tolerate as high sildenafil blood concentrations as 10 times those usually requested and did not report any significant adverse reaction to sildenafil during the follow-up period. Therapeutic drug monitoring should be considered during sildenafil therapy in patients concomitantly treated with ritonavir-boosted PI.

    Le complicanze vascolari dopo il trapianto renale non sono comuni, e nella maggior parte dei casi si presentano nel periodo post-trapianto precoce. Gli pseudoaneurismi arteriosi coinvolgono l’anastomosi arteriosa del rene trapiantato e nella maggior parte dei casi riconoscono una eziologia micotica. Una donna di 62 anni, che è stata sottoposta otto mesi prima ad un trapianto renale, presentava un vago dolore in fossa iliaca destra. L’ecografia del rene trapiantato dimostrava la presenza di un’area ipoecogena in corrispondenza dell’ilo renale, che all’ecocolordoppler appariva riccamente vascolarizzata. La tomografia computerizzata confermava la diagnosi di pseudo-aneurisma anastomotico di 33 mm di diametro, coinvolgente l’arteria del rene trapiantato. La paziente è stata dunque sottoposta a intervento chirurgico di aneurismectomia, con successivo bypass fra arteria renale del rene trapiantato e arteria iliaca interna. La continuità arteriosa iliaca è stata dunque ristabilita attraverso un by-pass iliaco-esterno-femorale comune in vena safena invertita. L’ecocolordoppler intraoperatorio dimostrava la corretta perfusione del graft renale e la corretta pervietà del by-pass iliacofemorale. Il decorso post-operatorio è stato privo di complicanze significative, eccettuata una linforrea inguinale risolta spontaneamente in 22a giornata post-operatoria. Sei mesi dopo la procedura, la paziente è in ottime condizioni generali, con una funzionalità renale conservata e una corretta pervietà del by-pass iliacofemorale. Lo pseudo-aneurisma dell’arteria renale rappresenta una rara complicanza del trapianto renale. Nella maggior parte dei casi riconosce una eziologia micotica, spesso a causa di contaminazione diretta del graft durante le procedure di prelievo o conservazione dell’organo. Il trattamento è molto complesso, e in molti casi richiede l’espianto del graft. Tuttavia, in alcuni casi selezionati, è possibile eseguire il trattamento dell’aneurisma, preservando il rene trapiantato, come nel caso da noi descritto. In conclusione, lo pseudoaneurisma dell’arteria renale è una complicanza rara ma potenzialmente letale del trapianto renale. L’intervento chirurgico di resezione dell’aneurisma, sebbene tecnicamente complesso, consente di preservare la funzionalità del rene trapiantato.

    Drug addiction has been one of the serious social problems. The peripheral phlebitis caused by drug injection is common, but the occurrence of pseudoaneurysm with infection of femoral artery from injection injury was rarely reported in China. From January 1995 to March 1996, six cases of injury of femoral artery with infection from heroine injection were admitted. The characteristics of the injury were described. The therapeutic measures and details of attention to be needed were discussed. It was concluded that this type of injury was different from the injury caused in agricultural, industrial or traffic accidents. The treatment of choice depended upon the type of injury.

    Gestational choriocarcinoma is easily disseminated hematogenously and its hypervascular nature places the patient at risk of significant hemorrhage both at the sites of metastatic lesion and in the uterus. In addition, its tends to give rise to pseudoaneurysm formation. Treatment of the condition by percutaneous embolization has been reported in several published articles, and hemoperitoneum secondary to rupture of splenic metastasis of gestational choriocarcinoma has also been reported, as has angiographic embolization. Hemoptysis resulting from pulmonary metastasis and treatment by means of embolization of the bronchial artery have not been reported, however. In this article, we describe a case of hemoptysis and hemoperitoneum due to pulmonary and splenic metastasis of gestational choriocarcinoma. Treatment of the condition involved embolization of the bronchial artery and superselective embolization of the splenic artery.

    Full Text Available INTRODUCTION Although the incidence is low, infection of prosthetic vascular graft bears a high incidence of serious complications including 25-75% mortality rate and 40-75% limb loss. The standard treatment of vascular graft infection consists of excision of the prosthesis, wound debridement and extraanatomic revascularization. Conservative treatment might be an option in a limited number of patients. We present three cases of surgical and conservative treatment of vascular graft infection. CASE OUTLINE Case 1: A patient developed silver-coated graft infection after femorodistal arterial reconstruction performed because of critical limb ischemia. In the early postoperative period, massive skin and subcutaneous tissue necrosis developed, with the graft being exposed. After two months of persistent debridement and wound toilette, the defect was covered with a Thiersch skin graft. Case 2: PTFE graft infection in the right groin followed reconstruction of the isolated common femoral artery aneurysm. This graft was replaced with a silver-coated graft in situ. Reinfection of the proximal end of the implanted silver-coated graft occurred and the graft was exposed. After repeated debridement and wound toilette, the exposed prosthesis was covered with granulomatous tissue, and the wound healed. Case 3: A year after anastomotic pseudoaneurysm resection in the left groin, prosthesis was exposed following wound infection. This graft was substituted with a silver-coated graft in situ. The wound healed primarily. CONCLUSION These three cases demonstrate that under some circumstances vascular prosthesis infection can be successfully treated conservatively without graft removal, and also by in situ replacement using silver-coated graft.

    2012-07-01

    Full Text Available A 54-year-old male patient presented with acute myocardial infarction involving left anterior descending and right coronary artery territories. Coronary angiogram showed a single coronary artery with right coronary artery arising from left anterior descending artery (LAD, which coursed anterior to right ventricular outflow tract and thrombotic lesion in mid left anterior descending artery before origin of right coronary artery. The patient was treated with thrombolytic therapy and glycoprotein IIb/IIIa inhibitors. Anomalous origin of right coronary artery as a branch of LAD is a very rare type of congenital coronary artery anomalies. It is important to recognize this anomaly as it can be associated with extensive myocardial ischemia and sudden cardiac death in young persons even without atherosclerosis.

    Pseudoaneurysm of mitral-aortic intervalvular fibrosa (P-MAIVF) is a rare cardiac surgical condition. P-MAIVF commonly occurs as a complication of aortic and mitral valve replacement surgeries. The surgical trauma during replacement of the valves weakens the avascular mitral and aortic intervalvular area. We present a case of P-MAIVF recurrence 5 years after a primary repair. Congestive cardiac failure was the presenting feature with mitral and aortic regurgitation. In view of the recurrence,...

  13. Renal Arteriovenous Fistula with Rapid Blood Flow Successfully Treated by Transcatheter Arterial Embolization: Application of Interlocking Detachable Coil as Coil Anchor

    International Nuclear Information System (INIS)

    A 70-year-old woman presented to our outpatient clinic with a large idiopathic renal arteriovenous fistula (AVF). Transcatheter arterial embolization (TAE) using interlocking detachable coils (IDC) as an anchor was planned. However, because of markedly rapid blood flow and excessive coil flexibility, detaching an IDC carried a high risk of migration. Therefore, we first coiled multiple loops of a microcatheter and then loaded it with an IDC. In this way, the coil was well fitted to the arterial wall and could be detached by withdrawing the microcatheter during balloon occlusion ('pre-framing technique'). Complete occlusion of the afferent artery was achieved by additional coiling and absolute ethanol. This technique contributed to a safe embolization of a high-flow AVF, avoiding migration of the IDC

    Kentaro Isoda

    Full Text Available BACKGROUND: Acute/subacute interstitial pneumonia in dermatomyositis (DM-A/SIP is a disease associated with a poor prognosis that resists treatment with glucocorticosteroids (GC and progresses rapidly in a period of weeks to months to death. We retrospectively studied outcomes, prognostic factors, and their relations with survival rate in patients with DM-A/SIP treated with early cyclosporine A (CSA/GC combination therapy and 2-hour postdose blood concentration monitoring. METHODS: This study comprised 32 DM-A/SIP patients who were simultaneously treated with CSA and prednisolone. Clinical and laboratory findings were compared between those who died due to DM-A/SIP and those surviving 24 weeks after beginning of therapy. Prognostic factors were extracted, and their relations with the survival rate were evaluated. RESULTS: Of the 32 DM-A/SIP patients, 25 survived, 5 died of DM-A/SIP, and 2 died of infections. In those who died due to DM-A/SIP, ferritin level and the alveolar-arterial oxygen gradient were significantly increased compared with the survivors (P<0.001 and P = 0.002, respectively. Multivariate analyses showed that ferritin and alveolar-arterial oxygen gradient were independent prognostic factors of poor outcome. The survival rate 24 weeks after beginning of treatment was significantly lower in those with a ferritin level of ≥ 600 ng/ml and alveolar-arterial oxygen gradient of ≥ 45 Torr (P<0.001 and P<0.001, respectively. All patients with both prognostic factors died, and the outcome was significantly poorer in these patients than in those with one or neither of the prognostic factors (P<0.001. CONCLUSIONS: We identified pre-treatment high serum ferritin level and high alveolar-arterial oxygen gradient as poor prognostic factors in DM-A/SIP patients undergoing early CSA/GC combination therapy and showed that the outcomes were poor in patients with both factors.

    Full Text Available Background: Our purpose was to investigate the clinical outcomes of Zotarolimus- and Paclitaxel-eluting stents in Turkish patients with coronary artery disease (CAD. In general, the outcome of drug-eluting stent (DES placement has a proven efficacy in randomized trials. However, the difference in efficacy between the Zotarolimus and Paclitaxel-eluting stents in unselected Turkish patients is controversial. Therefore, we investigated the clinical outcomes of these two drug-eluting stents in the real-world.Methods: We created a registry and prospectively analyzed data on a consecutive series of all patients who presented to our institution with symptomatic coronary artery disease between February 2005 and March 2007 and who were treated with the zotarolimus- or the paclitaxel-eluting stent. The follow-up period was approximately two years. The primary end-point was major cardiac events, and the secondary end-point was definite stent thrombosis. Informed consent was obtained from all subjects, and the study protocol was approved by the local ethical committee.Results: In total, 217 patients were treated with either the zotarolimus-eluting stent (n = 116 or the paclitaxel-eluting stent (n = 101. The lesions in the 2 arms of the study were treated similarly by conventional technique. At 24-month follow-up the paclitaxel-eluting stent group showed significantly higher non-Q wave myocardial infarction (2.6% vs 5.9%, p: 0.02, Q wave myocardial infarction (1.7% vs 5.9%, p: 0.049, coronary artery binding graft surgery (2.6% vs 6.9%, p: 0.002, and late stent thrombosis (1.7% vs 3.9%, p: 0.046.Conclusions: Zotarolimus-eluting stents demonstrated better clinical outcomes than Paclitaxel-eluting stents in a daily routine practice of coronary intervention in an unselected Turkish population.

    Liver injury in blunt abdominal trauma is common. However, not often does blunt trauma cause injury to the anatomical structures of the porta hepatis. Isolated injury of the hepatic artery has been rarely reported in the literature. Such injury may be lethal and requires immediate diagnosis and management. This report describes an unusual case of blunt abdominal trauma resulting in hepatic and gastroduodenal artery dissection, with pseudoaneurysm formation complicated by active upper gastrointestinal bleeding. The injury was managed by transcatheter embolisation. Awareness of this diagnosis should facilitate management of similar trauma cases.

    A patient presented with hematemesis due to gastric variceal bleeding with an intratumoral arterioportal shunt. Contrast-enhanced CT revealed gastric varices and hepatocellular carcinoma with tumor thrombi in the right portal vein. Angiography and angio-CT revealed a marked intratumoral arterioportal shunt accompanied with reflux into the main portal vein and gastric varices. Balloon-occluded retrograde venography from the gastro-renal shunt showed no visualization of gastric varices due to rapid blood flow through the intratumoral arterioportal shunt. The hepatic artery was temporarily occluded with a balloon catheter to reduce the blood flow through the arterioportal shunt, and then concurrent balloon-occluded retrograde transvenous obliteration (BRTO) was achieved. Vital signs stabilized immediately thereafter, and contrast-enhanced CT revealed thrombosed gastric varices. Worsening of hepatic function was not recognized. BRTO combined with temporary occlusion of the hepatic artery is a feasible interventional procedure for ruptured high flow gastric varices with an intratumoral arterioportal shunt.

    There are multiple causes of worsening graft function after initial good function in cadaveric kidney transplant. In this report, we discuss a rare one: a traumatic pseudoaneurysm caused by a 14-gauge core needle biopsy in a 55-year-old woman. She had immediate graft function followed by rapid decline in the first postoperative week. Imaging studies showed an intraparenchymal 2-cm pulsatile mass with turbulent blood flow in the upper pole at the corticomedullary junction. Angiography the following morning confirmed the diagnosis of pseudoaneurysm. It was coiled successfully, with restoration of graft function. Although development of a pseudoaneurysm is a rare event, transplant centers must be cognizant of allograft injuries like this one. PMID:21911162

    The Pipeline embolization device (PED) is one of the flow-diverting stents approved for the treatment of unruptured large or wide-necked cerebral aneurysms in 2011(1). Its use has now been extended to the treatment of recently ruptured dissecting cerebral aneurysm, carotid pseudoaneurysm from radiation injury, and blister aneurysms(2,3). We aimed to evaluate the effectiveness of utilizing the PED as a primary treatment for ruptured dissecting intracranial aneurysms. A single center retrospective review was conducted for all patients primarily treated with PED for acute subarachnoid hemorrhage (SAH) from ruptured dissecting cerebral aneurysms between December 2010 and February 2013. Patients were followed up with CT angiogram (CTA) or digital subtraction angiogram (DSA). Eight patients with a total of eight dissecting aneurysms were identified. The mean duration from SAH to treatment was 2.5 days. Six of the aneurysms arose from vertebral arteries and two from the basilar artery. Immediate check-DSA confirmed satisfactory contrast stasis in all eight cases, and complete aneurysmal obliteration was achieved at six months. There were two (25%) procedure-related complications, but no major procedure-related complications, such as thromboembolic events or rebleeding from aneurysm were encountered. The PED is a feasible treatment option for ruptured dissecting cerebral aneurysms in acute phase. According to our experience, using PED as flow-diverters in acute SAH does not significantly increase the complication risks or mortality rate if the antiplatelet regime is carefully monitored. Future studies shall evaluate the optimal antiplatelet regimen for using the PED in the acute phase. PMID:25207906

    Full Text Available Introduction. Splanchnic artery aneurysms are uncommon but important vascular entity because nearly 25% of all cases present as surgical emergency. Objective. The purpose of our study was to present nine patients operated on at the Institute of cardiovascular diseases, as well as literature review of clinical presentation of the disease. Method. There were three splenic artery aneurysms, two celiac trunk aneurysms, and one aneurysm of the hepatic, superior mesenteric, inferior mesenteric and gastroduodenal artery. All patients were males, mean aged 67.5 years (60-73. In four patients, splanchnic artery aneurysm was discovered accidentally during routine ultrasonographic and angiographic examinations of the abdominal aorta. At that time, arteriovenous fistula was diagnosed in a patient No 1; it was formed after rupture of the splenic artery aneurysm into the splenic vein. Three aneurysms were manifested by abdominal pain and palpable pulsating abdominal mass. Two patients were admitted as urgent cases in the state of hemorrhagic shock and signs of intraabdominal bleeding due to rupture of the splenic and hepatic arteries. In 7 cases, diagnosis was made preoperatively by means of ultrasonography and angiography; in two patients, accurate diagnosis was confirmed during surgery. Results. Proximal and distal ligation of the artery was performed in a patient with rupture of the splenic aneurysm into the splenic vein that caused arteriovenous fistula. Gastroduodenal artery aneurysm was treated by trans-aneurysmatic ligation of its "entering" and "exiting" branches. Aneurysms of distal part of the superior mesenteric and splenic artery were resected without further reconstruction. Partial resection of the aneurysm and endoaneurysmorrhaphy was carried out in one case of celiac trunk aneurysm, and in another, after aneurysm resection, the restoration of blood flow through the hepatic and lienal artery was achieved by Dacron grafts.

    This study sought to determine whether the permeability related parameter K(trans), derived from computed tomography perfusion (CTP) imaging, can predict hemorrhagic transformation (HT) in patients with acute ischemic stroke who receive intra-arterial thrombolysis. Data from patients meeting the criterion were examined. CTP was performed and K(trans) maps were used to assess the permeability values in HT and non-HT regions. A receiver operating characteristic (ROC) curve was calculated, showing the sensitivity and specificity of K(trans) for predicting HT risk. Composite images were produced to illustrate the spatial correlations among perfusion, permeability changes and HT. This study examined 41 patients. Twenty-six patients had hemorrhagic infarction and 15 had parenchymal hemorrhage. The mean K(trans) value in HT regions was significantly lower than that in the non-HT regions (0.26 ± 0.21/min vs. 0.78 ± 0.64/min; P < 0.001). The ROC curve analysis identified an optimal cutoff value of 0.334/min for K(trans) to predict HT risk. Composite images suggested ischemic regions with low permeability, or the mismatch area of low perfusion and high permeability, more likely have HT. HT regions after intra-arterial thrombolysis had lower permeability values on K(trans) maps. The mismatch area of lower perfusion and higher permeability are more likely to develop HT. PMID:27302077

    Obese patients are prone to arterial hypertension, require more antihypertensive medications, and have an increased risk of treatment-resistant arterial hypertension. Obesity-induced neurohumoral activation appears to be involved. The association between obesity and hypertension shows large inter-individual variability, likely through genetic mechanisms. Obesity affects overall cardiovascular and metabolic risk; yet, the relationship between obesity and cardiovascular risk is complex and not sufficiently addressed in clinical guidelines. The epidemiological observation that obesity may be protective in patients with established cardiovascular disease is difficult to translate into clinical experience and practice. Weight loss is often recommended as a means to lower blood pressure. However, current hypertension guidelines do not provide evidence-based guidance on how to institute weight loss. In fact, weight loss influences on blood pressure may be overestimated. Nevertheless, weight loss through bariatric surgery appears to decrease cardiovascular risk in severely obese patients. Eventually, most obese hypertensive patients will require antihypertensive medications. Data from large-scale studies with hard clinical endpoints on antihypertensive medications specifically addressing obese patients are lacking and the morbidity from the growing population of severely obese patients is poorly recognized or addressed. Because of their broad spectrum of beneficial effects, renin-angiotensin system inhibitors are considered to be the most appropriate drugs for antihypertensive treatment of obese patients. Most obese hypertensive patients require two or more antihypertensive drugs. Finally, how to combine weight loss strategies and antihypertensive treatment to achieve an optimal clinical outcome is unresolved.

    textabstractBACKGROUND Percutaneous coronary intervention (PCI) involving drug-eluting stents is increasingly used to treat complex coronary artery disease, although coronary-artery bypass grafting (CABG) has been the treatment of choice historically. Our trial compared PCI and CABG for treating patients with previously untreated three-vessel or left main coronary artery disease (or both). METHODS We randomly assigned 1800 patients with three-vessel or left main coronary artery disease to und...

    The safety and clinical effectiveness of transcatheter arterial embolization for bleeding associated with unresectable gastric cancer was evaluated. Twenty-three patients with bleeding from unresectable gastric cancer underwent transcatheter arterial embolization. Of the 23 patients, eight showed signs of active bleeding, such as contrast extravasation or pseudoaneurysm, seven showed only tumor staining, and the remaining eight patients showed negative angiographic findings. All embolization procedures were successful without procedure-related complications. In all eight active bleeding patients, immediate hemostasis was achieved. The overall clinical success rate was 52% (12/23). Recurrent bleeding within 1 month occurred in one (8%) in 12 patients with initial clinical success. One patient showed partial splenic infarction after embolization of the splenic artery for active bleeding from the short gastric artery. Overall 30-day mortality rate was 43% (10/23). The median overall survival period was 38 days. In patients with bleeding from unresectable gastric cancer, transcatheter arterial embolization was found to be safe and effective for achieving immediate hemostasis for active bleeding. Although the clinical success rate was not high, the recurrent bleeding rate was low at 1 month post procedure. (orig.)

    Full Text Available Basilar artery thrombosis has high morbidity and mortality. Though intra-arterial thrombolytics have proven efficacy in the treatment of acute basilar artery occlusion, the elevation of procoagulant factors in the blood after intra-arterial thrombolysis could result in subsequent thrombus formation and clinical deterioration. Glycoprotein IIb/IIIa inhibitors have been shown to reduce this elevation in procoagulants. We present a pilot study of three cases of acute basilar artery occlusion treated with a combination of intra-arterial thrombolytics and Gp IIb/IIIa inhibitor with remarkable clinical recovery seen in all the patients.

    Results of the two-stage arterial switch operation in 49 patients with transposition of the great arteries, performed between January 1995 and September 2000, were reviewed retrospectively. Twenty-one patients had a ventricular septal defect. Anatomical correction was carried out 21.89 +/- 9.86 months after pulmonary artery banding, with or without a modified Blalock-Taussig shunt. Hospital mortality was 8% (4 patients). During follow-up of 30.12 +/- 14.38 months, there was 1 late death and 1 patient required reoperation for pseudoaneurysm of the ascending aorta. Actuarial survival and freedom from reoperation at 5 years were 90% and 97%, respectively. Late anatomic correction (> 6 months) after the preliminary procedure can be performed with an acceptable mortality and morbidity, but undue delay may lead to left ventricular dysfunction, arrhythmias, and new aortic valve regurgitation or subaortic stenosis.

  2. Emergency embolization in the treatment of intractable epistaxis resulted from carotid arterial disease

    International Nuclear Information System (INIS)

    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.

    2015-06-15

    Background/Purpose: The ORBIT I trial, a first-in-man study, was conducted to evaluate the safety and performance of the orbital atherectomy system (OAS) in treating de novo calcified coronary lesions. Methods/Materials: Fifty patients were enrolled between May and July 2008 based on several criteria, and were treated with the OAS followed by stent placement. The safety and performance of the OAS were evaluated by procedural success, device success, and overall major adverse cardiovascular event (MACE) rates, including cardiac death, myocardial infarction (MI) and need for target lesion revascularization (TLR). Our institution enrolled and treated 33 of the 50 patients and continued follow-up for 5 years. Results: Average age was 54 years and 91% were males. Mean lesion length was 15.9 mm. Device success was 100%, and average number of orbital atherectomy devices (OAD) used per patient was 1.3. Stents were placed directly after OAS in 31/32 patients (96.9%). All stents (average stent per lesion 1.1) were successfully deployed with 0.3% residual stenosis. The overall cumulative MACE rate was 6.1% in-hospital, 9.1% at 30 days, 12.1% at 6 months, 15.2% at 2 years, 18.2% at 3 years and 21.2% at 5 years (4 total cardiac deaths). None of the patients had Q-wave MIs. Angiographic complications were observed in 5 patients. No flow/slow flow due to distal embolization was observed. Conclusions: The ORBIT I trial suggests that OAS treatment continues to offer a safe and effective method to change compliance of calcified coronary lesions to facilitate optimal stent placement in these difficult-to-treat patients.

    Full Text Available Background/Aim. Intramyocardial bone marrow mononuclear cells (BMMNC implantation concomitant to coronary artery bypass grafting (CABG surgery as an option for regenerative therapy in chronic ischemic heart failure was tested in a very few number of studies, with not consistent conclusions regarding improvement in left ventricular function, and with a follow-up period between 6 months and 1 year. This study was focused on testing of the hypothesis that intramyocardial BMMNC implantation, concomitant to CABG surgery in ischemic cardiomyopathy patients, leads to better postoperative long-term results regarding the primary endpoint of conditional status-functional capacity and the secondary endpoint of mortality than CABG surgery alone in a median follow-up period of 5 years. Methods. A total of 30 patients with ischemic cardiomyopathy and the median left ventricular ejection fraction (LVEF of 35.9 ± 4.7% were prospectively and randomly enrolled in a single center interventional, open labeled clinical trial as two groups: group I of 15 patients designated as the study group to receive CABG surgery and intramyocardial implantation of BMMNC and group II of 15 patients as the control group to receive only the CABG procedure. All the patients in both groups received the average of 3.4 ± 0.7 implanted coronary grafts, and all of them received the left internal mammary artery (LIMA to the left anterior descending (LAD and autovenous to other coronaries. Results. The group with BMMNC and CABG had the average of 17.5 ± 3.8 injections of BMMNC suspension with the average number of injected bone marrow mononuclear cells of 70.7 ± 32.4 × 106 in the total average volume of 5.7 ± 1.5 mL. In this volume the average count of CD34+ and CD133+ cells was 3.96 ± 2.77 × 106 and 2.65 ± 1.71 × 106, respectively. All the patients were followed up in 2.5 to 7.5 years (median, 5 years. At the end of the follow-up period, significantly more patients from the group

    Among the neoplastic conditions that affect patients with neurofibromatosis Type 1 (NF1) are malignant peripheral nerve sheath tumors (MPNSTs), which typically arise from peripheral nerves of the limbs, trunk, and lumbar and brachial plexuses. Ionizing radiation is an established risk factor for MPNST development, especially in susceptible patients such as those with NF1. Patients with NF1 are also at risk for intracranial aneurysms, which are increasingly being successfully managed with endovascular therapies. The authors describe the case of a 9-year-old, previously healthy girl who presented in extremis with a right frontal intracerebral hemorrhage resulting from a ruptured right middle cerebral artery (MCA) trifurcation aneurysm. Following urgent decompressive craniectomy, the patient underwent endovascular coil embolization of the MCA aneurysm without complication. Given her mother's history of NF1, the child underwent genetic testing, which disclosed signs positive for NF1. The patient recovered well, but follow-up MR imaging and MR angiography performed at 14 months demonstrated a large frontotemporal mass encasing the right MCA trifurcation. The patient underwent frontotemporal craniotomy and subtotal resection of the mass, which was histologically found to be an intracranial MPNST. The patient received chemotherapy and focal radiation therapy and remains alive at 6 months postresection. To the authors' knowledge, this represents the only known case of intracranial neoplasm arising in the region of an intracranial aneurysm repaired by endovascular coil embolization. While patients with NF1 represent a population with genetic susceptibility to radiation-induced tumors, the pathogenesis of intracerebral MPNSTs remains poorly understood. PMID:21961539

    To prospectively evaluate safety and efficacy of a novel vascular closure device (Glubran 2 Seal) after peripheral angiography in patients with peripheral arterial occlusive disease (PAOD). From December 2010 to June 2011, all consecutive patients with PAOD undergoing peripheral angiography were prospectively enrolled onto the study after percutaneous antegrade or retrograde puncture of the common femoral artery. After angiography, the Glubran 2 Seal device was used to achieve hemostasis. The following data were registered: technical success and manual compression duration, patients' discomfort (scale 0-5), operators' technical difficulty (scale 0-5), and vascular complications. The site of hemostasis was evaluated by clinical inspection and color-coded Duplex ultrasound performed 1 day and 1 month after the procedure. One hundred seventy-eight patients were enrolled (112 male, mean age 70.8 years) with a total of 206 puncture sites, including 104 (50.5 %) antegrade accesses. The device was successful in 198(96.1 %) of 206 procedures, with 8 cases of manual compression lasting longer than 5 min (maximum 20 min). No major vascular complications were observed, resulting in 100 % procedural success. Minor complications occurred in seven procedures (3.4 %), including two cases of pseudoaneurysms, successfully treated by ultrasound-guided glue injection. The mean {+-} standard deviation score for patients' discomfort was 0.9 {+-} 0.7, whereas the mean score for operators' difficulty was 1.2 {+-} 0.9. In patients with PAOD, the Glubran 2 Seal represents a simple, painless, and efficient vascular closure device, able to achieve hemostasis both in antegrade and retrograde accesses.

    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.

    2012-01-01

    Full Text Available The patient is a 75-year-old man with a history significant for hypertension and congestive heart failure who underwent a bioprosthetic aortic valve replacement secondary to acute onset of aortic insufficiency. Cultures of the native valve were positive for Staphylococcus epidermidis sensitive to nafcillin and intravenous cefazolin was initiated. On postoperative day 24, he developed acute decompensated heart failure. A transesophageal echocardiogram demonstrated a structurally abnormal mitral valve with severe regurgitation, anterior and posterior leaflet vegetations, and scallop prolapse. There was also evidence of a mitral-aortic intervalvular fibrosa pseudoaneurysm (P-MAIF with systolic expansion and flow within the aneurysm. Antibiotic treatment was changed from cefazolin to vancomycin for presumed development of methicillin-resistant Staphylococcus. He subsequently underwent a bioprosthetic mitral valve replacement and has restoration of health without sequella. This case highlights the development of a P-MAIF as a rare complication of both aortic or mitral valve replacement and infective endocarditis.

  11. Combination of traumatic thoracic aortic pseudoaneurysm and myocardial contusion leading to left ventricular aneurysm

    International Nuclear Information System (INIS)

    The combination of thoracic aortic pseudoaneurysm and left ventricular aneurysm resulting from a single traumatic incident is an exceedingly rare occurrence. We present a case of a 10-year-old girl who sustained significant blunt trauma to the chest after being involved in a rollover motor vehicle accident. The child underwent immediate repair of a transected aortic arch. An inferior wall left ventricular aneurysm developed 3 weeks later, and the patient underwent successful repair of the left ventricular aneurysm and a damaged mitral valve. The use of fast multidetector row CT, cardiac MRI, and echocardiography have improved our ability to diagnose these types of injuries and accurately image their anatomic relationships in the acute and perioperative settings.

    In patients with pulmonary arterial hypertension (PAH), chest pain is most likely due to right ventricular demand ischemia. We report a patient with idiopathic PAH who developed severe angina due to extrinsic compression of the left main coronary artery (LMCA) from a dilated pulmonary artery trunk....... The diagnosis was verified by electrocardiogram after exercise, coronary angiography including intravascular ultrasound, and cardiac multidetector computed tomography (MDCT). The origin of the LMCA was high in the left coronary sinus, facilitating extrinsic compression. The patient was successfully treated...

  15. Effects of Acupressure on Fatigue and Depression in Hepatocellular Carcinoma Patients Treated with Transcatheter Arterial Chemoembolization: A Quasi-Experimental Study

    Full Text Available This study was to examine the effects of acupressure on fatigue and depression in HCC patients undergoing TACE. A quasiexperimental study design was used. Patients were evaluated at five time points: before treatment (T1 and 2, 3, 4, and 5 days after treating TACE (T2, T3, T4, and T5. Fatigue and depression were assessed by a VAS fatigue scale and a VAS depression scale at each time point. TFRS and BDI were administered at T1 and T5. Patients’ fatigue and depression were significantly higher at T5 than at T1 in two groups. Fatigue and depression increased in both the experimental and control groups’ patients over the five days of hospitalization during which TACE and chemotherapy were administered. The experimental group had significantly less fatigue than the control group, with lower subscale scores on physical, psychosocial, daily, and overall fatigue. There were no differences between the groups on depression. At posttest, the experimental group experienced lower physical, psychosocial, daily, and overall fatigue than the control group. Acupressure can improve fatigue in HCC patients during treatment with TACE but did not alleviate depression. Discharge planning should include home care for management of fatigue and depression.

    Using a system pharmacology strategy, this study evaluated the unique pharmacological characteristics of three different neuroprotective compounds for the treatment of cerebral ischemia-reperfusion. A microarray including 374 brain ischemia-related genes was used to identify the differentially expressed genes among five treatment groups: baicalin, jasminoidin, ursodeoxycholic acid, sham, and vehicle, and MetaCore analysis software was applied to identify the significantly altered pathways, processes and interaction network parameters. At pathway level, 46, 25, and 31 pathways were activated in the baicalin, jasminoidin, and ursodeoxycholic acid groups, respectively. Thirteen pathways mainly related with apoptosis and development were commonly altered in the three groups. Additionally, baicalin also targeted pathways related with development, neurophysiologic process and cytoskeleton remodeling, while jasminoidin targeted pathways related with cell cycle and ursodeoxycholic acid targeted those related with apoptosis and development. At process level, three processes were commonly regulated by the three groups in the top 10 processes. Further interaction network analysis revealed that baicalin, jasminoidin, and ursodeoxycholic acid displayed unique features either on network topological parameters or network structure. Additional overlapping analysis demonstrated that compared with ursodeoxycholic acid, the pharmacological mechanism of baicalin was more similar with that of jasminoidin in treating brain ischemia. The data presented in this study may contribute toward the understanding of the common and differential pharmacological mechanisms of these three compounds. PMID:26168995

    The aim of this study was evaluation of a closure device (Perclose, Menlo Park, Calif.) for closure of the femoral artery access site in patients undergoing aggressive anticoagulation and platelet blockade after carotid stenting. Fifty-five patients who received clopidogrel in addition to aspirin and heparin as medication for carotid stenting were included for suture of the femoral access site after using 7- or 8-F guide catheters. The technical success, the time for suture, the clotting parameters, and complications were examined. Follow-up investigations, including ultrasound and clinical examinations, were performed. The groin was checked for possible hematoma, pseudoaneurysm, arteriovenous fistula, and local infection. Technical success was obtained in 51 of 54 patients (94%) after a mean procedure time of 6 min (range 5-10 min). The suture device was not used in one patient (2%) for anatomical reasons and failed to obtain hemostasis in 3 of 54 (6%) patients. In 4 of 54 patients (7%) bleeding was observed at the punctured site 4-6 h after intervention which was treated by a compression bandage. The mean dedicated activated clotting time was 137 s (range 29-287 s) before intervention and 349 s (150-958 s) just before deploying the Perclose device. During follow-up after 2 days (range 2-6 days) and 6 months no further complications of the puncture site were observed except for two large groin hematomas. No major complications occurred. Closure of the femoral access site after carotid stenting using a Perclose closure device is safe and effective even in patients receiving an aggressive anticoagulation and antiplatelet therapy.

    PURPOSE: To evaluate the ability of multi-detector row computed tomography angiography (CTA) in detecting hepatic artery complications in the follow-up of liver transplant patients, performing volume-rendering as reconstruction technique. MATERIAL AND METHODS: The anatomy of hepatic artery was studied in 27 liver transplant recipients with a four-row CT scanner using the following parameters: collimation, 1 mm; slice width, 1 mm; table feed, 6-8 mm/s; spiral reconstruction time, 0.5 s; reconstruction interval, 0.5 mm; mAs, 160; kVp, 120. Before the study, the patients received 1000 ml of water as oral contrast agent to produce negative contrast in the stomach and the small bowel. A non-ionic contrast medium was infused intravenously at a rate of 5 ml/s with a bolus tracking system. Volume-rendering of hepatic artery was performed with the 3D Virtuoso software. RESULTS: The celiac trunk, the hepatic artery, and the right and left hepatic arteries were successfully displayed in high detail in all patients. Side branches, including small collaterals, and hepatic artery anastomosis could also be readily visualized. Volume-rendered CTA detected six hepatic artery stenoses, two hepatic artery thromboses, and two intrahepatic pseudoaneurysms. In two cases, CT detected hepatic artery stenosis with a diameter reduction of less than 50%, while digital subtraction angiography showed a normal artery. CONCLUSION: Volume-rendered multi-detector CTA is a promising non-invasive technique, since it allows images of high quality to be generated with excellent anatomical visualization of the hepatic artery and its complications in liver transplant recipients.

    Postpartum hemorrhage (PPH) is a potentially life-threatening condition, which needs multidisciplinary management. Uterine atony represents up to 80 % of all causes of PPH. Transcatheter arterial embolization (TAE) has now a well-established role in the management of severe PPH. TAE allows stopping the bleeding in 90 % of women with severe PHH, obviating surgery. Pledgets of gelatin sponge as torpedoes are commonly used for safe TAE, and coils, glue, and microspheres have been primarily used in specific situations such as arterial rupture, pseudoaneurysm, and arteriovenous fistula. TAE is a minimally invasive procedure with a low rate of complications, which preserves future fertility. Knowledge of causes of PPH, potential risks, and limitations of TAE is essential for a timely decision, optimizing TAE, preventing irreversible complications, avoiding hysterectomy, and ultimately preserving fertility.

    1996-01-01

    Over a period of 5 years 81 vascular complications after 15,460 catheterizations of the femoral artery for diagnostic (n = 11,883) or therapeutic (n = 3577) procedures were registered. The following complications were observed in declining frequency: 1. False aneurysm (n = 65), 2. arterial occlusion (dissection, embolia, thrombosis) (n = 8), 3. vascular lesion causing profuse bleeding (n = 7), 4. AV-fistula (n = 1). The total complication rate was 0.52%. The complication rate was significantly higher in therapeutical procedures (1,03%) than in diagnostic investigations (0.37%). Pseudoaneurysms were complicated by thrombosis of the femoral vein (n = 3), lymphatic fistula (n = 3) and deep wound infection (n = 9); secondary complication rate 18.5%. Risk factors for local vascular complications are old age, female gender, high grade arteriosclerosis at the puncture site, overweight, manifest arterial hypertension and medication with cumarin, acetylsalicylic acid or heparin. Further complicating factors are connected with technical risks such as duration of the procedure. French size of the catheter, the catheter sheath and multiple punctures. Vascular repair was performed by simple angiography in most cases, but in 14.8% more extensive surgical procedures were required. In patients with signs of occlusive vascular disease the external iliac artery was replaced by a PTFE-vascular access graft in 4 cases and an arterioplasty of the deep femoral artery was performed in 2 patients. 36% of the operations were undertaken as emergencies. Reintervention was necessary for a postoperative bleeding complication in 1 case (surgical complication rate 1.2%). A female patient suffering from aortic valve stenosis died during emergency operation due to massive retroperitoneal hemorrhage after cardiac catheterization (mortality rate 1.2%). Over a median follow-up period of 37 months no late complications of the intervention were recorded, nor recurrences of peripheral arterial occlusive

    Purpose: Major arterial hemorrhage is an uncommon but serious complication of pancreatitis with high morbidity and mortality. Digital subtraction angiography (DSA) has long been the gold standard for the detection of a visceral artery pseudoaneurysm or for the site of active bleeding in patients with pancreatitis. Multi-section CT angiography is a minimally invasive technique which can provide high-resolution and high-contrast images of the arterial lumen and wall, with a much lower risk of complication and morbidity compared to DSA. The aim of this study was to determine the accuracy of multi-section CT angiography for the diagnosis of arterial complications of inflammatory pancreatitic disease. Materials and methods: A retrospective analysis of all patients undergoing visceral angiography for major bleeding as a complication of pancreatitis between 1998 and 2004 was performed. Twenty-nine studies in 25 patients (20 males, 5 females) with a mean age of 50.9 years (range 11-67 years) were identified where multi-section CT angiography was performed in the 24 h preceding the digital subtraction angiogram. Results: Digital subtraction angiography detected a pseudoaneurysm or contrast extravasation in 19 studies and no bleeding was demonstrated in 9 studies. CT angiography correctly identified the site and type of bleeding in 18 of the 19 positive studies. CT angiography detected extravasation of contrast in one study that was not demonstrated on digital subtraction angiography. The sensitivity and specificity for multi-section CT angiography for the detection of major arterial bleeding on a background of pancreatitis were 0.947 and 0.900, respectively. Conclusion: Multi-section CT angiography is a sensitive and accurate technique for the detection of major arterial hemorrhage in inflammatory pancreatic disease and should be considered as the first investigation in the management of these patients.

    2013-01-01

    Full Text Available Background: Carotid endarterectomy (CEA and carotid artery stenting (CAS are safe, effective, and standard methods to treat significant carotid artery stenosis. CAS is generally performed through femoral arterial access. We had six patients with significant carotid artery stenosis, who had difficult anatomy prohibiting a trans-femoral CAS. Those patients were given an option for CEA. However, they refused for surgical intervention. Aim: We investigated the feasibility of performing CAS from a non-femoral arterial approach in patients with difficult anatomies like severe aortic/aorto-iliac disease, tortuous aortic arch, and tortuous carotid artery origin. Materials and Methods: Six patients with difficult anatomy presented to us with either transient ischemic attack or stroke with high-grade carotid artery stenosis. Out of the six patients, three had aorto-iliac disease, one had high-grade coarctation of aorta, two had tortuous aortic arch and or tortuous carotid artery origin. All these patients were treated with CAS though non-femoral arterial route. Results: CAS could be done successfully in all these six patients; four of them were done through trans-brachial arterial route and two were done through a direct carotid artery puncture. There were no new neurological deficits seen in any of the patient post-procedure. Conclusion: CAS can be done safely through non-femoral arterial approach in patients with difficult anatomy.

  13. Fatal dissection of the pulmonary artery in pulmonary arterial hypertension

    Full Text Available A 41-yr-old patient with chronic stable idiopathic pulmonary arterial hypertension (PAH presented with sudden chest pain and unusual dyspnoea during physical exertion. The patient had been diagnosed with PAH at the age of 12 yrs and was in New York Heart Association functional class I/II. The patient was being treated with an anticoagulant regimen, low-dose diuretics and continuous intravenous epoprostenol therapy. A computed tomography scan showed ancient massive thrombi in dilated central pulmonary arteries, which were not haemodynamically significant (perfusion lung scans did not demonstrate segmental or larger defects, and extensive dissection of the right pulmonary artery starting from the intermediate branch. Due to the extensiveness of the dissection, the patient was immediately considered for heart–lung transplantation, but died 72 h after the onset of symptoms. Permission for post mortem examination was denied. Pulmonary artery dissection should be suspected in PAH patients presenting with chest pain and worsening dyspnoea. In the current case, the factors possibly associated with increased risk for dissection may include dilatation of the pulmonary artery, local inflammation favoured by in situ thrombosis, and acute increase of pulmonary pressure secondary to physical exertion. Extensive pulmonary artery dissection is a life-threatening complication of PAH, and urgent heart/lung transplantation might be the treatment of choice in eligible patients. In addition, better identification of the risk factors for pulmonary artery dissection may help in considering transplantation for selected patients at risk.

    Full Text Available Introduction. Behçet's disease (BD is a form of vasculitis of unknown etiology which is rare in our environment. It is characterized by a variety of clinical manifestations and usually affects young adults. Recurrent oral and genital ulcers are a characteristic and extremely frequent symptom, but mortality is linked with more significant symptoms such as aortic pseudoaneurysm, pulmonary pseudoaneurysm, and cerebral venous thrombosis. Patient and Method. We present a case of a young male with atypical BD and severe polyvascular involvement (previous cerebral venous thrombosis and current peripheral venous thrombosis, acute ischemia, and peripheral arterial pseudoaneurysm who required urgent surgical intervention due to a symptomatic external iliac pseudoaneurysm. Result. The pseudoaneurysm was successfully treated, we performed an iliofemoral bypass, and we treated it with steroids and immunosuppressive therapy. Conclusions. These rare clinical manifestations highlight the importance of considering BD in young patients, even in usual cases of vascular intervention, whether arterial or venous in nature.

    Full Text Available Caliber-persistent artery (CPLA of the lip is a common vascular anomaly in which a main arterial branch extends to the surface of the mucous tissue with no reduction in its diameter. It usually manifests as pulsatile papule, is easily misdiagnosed, and is observed more frequently among older people, suggesting that its development may involve a degenerative process associated with aging; CPLA is also characterized by the loss of tone of the adjacent supporting connective tissue. Although the diagnosis is clinical, high-resolution Doppler ultrasound is a useful noninvasive tool for evaluating the lesion. This report describes the case of a 58-year-old male patient who complained of a lesion of the lower lip with bleeding and recurrent ulceration. The patient was successfully treated in our hospital after a diagnosis of CPLA and is currently undergoing a clinical outpatient follow-up with no complaints.

    Abdominal aortic pseudoaneurysm (AAP) is a rare lesion, although traumatic aortic injury is described as one of the main causes; both the rupture as the surgical treatment of the defect has high morbidity and mortality. Therefore, endovascular treatment either by chemical embolization or exclusion of defect with devices has emerged as an alternative treatment. However, there are risks such as occlusion of visceral vessels near the neck of the defect, embolization material or aortic rupture. Therefore, the choice of material and method of approach should be planned carefully in each case. We report a patient who ten years after abdominal wound firearm was diagnosed with AAP 17 x 13 cm, with short neck originated close to the ostium of the celiac trunk at an acute angle with the aortic axis. We perform the exclusion of the defect with a device designed for closing atrial septal defect from the left brachial access due to the angulation of the neck defect. There were no complications. At 72 hours was granted discharge. A month later, CT scan control showed the false aneurysm of equal size and no residual flow. The monitoring to date is five months and the patient remained asymptomatic.

    The authors analyzed 30 patients whose celiac artery or its branches were dissected during the procedure of transcatheter arterial embolization (TAE) for hepatocellular carcinoma (HCC) and were followed up angiographically. The incidence of arterial dissection was 1.25%. The dissection occurred most frequently in the celiac artery (40% 12/30) and the proper hepatic artery (28% 7/30). The frequency of arterial dissection was affected by the status of the vessel and the experience of the operator. The follow-up angiography revealed complete recanalization in 40% (12/30), irregularity and narrowing of the lumen in 23% (7/30), pseudoaneurysm formation in 23% (7/30), and complete obstruction in 13% (4/30) of the cases. The rate of recanalization in the celiac artery was lower than that of any other arteries in our series. Recanalization to a certain degree without therapeutic intervention was observed in 72% of the dissected arteries enabling and contributing to subsequent successful TAE within 2 months in 78% of the patients with the dissection.

    Objective: To investigate efficacy and effect on liver function of the experimental therapy with balloon catheter to block the main artery temporarily and then pressurize chemoembolization to treat hypovascular liver cancer. Methods: Eighty patients with hypovascular liver cancer requiring interventional therapy were randomly divided into two groups. The experimental group was treated with the new therapy and the control group was treated with traditional therapy. The lipiodol-filling status and maximum diameter of the tumor was analyzed for a midterm outcome, and the change of AFP and liver function were evaluated. Mann-Whitney test was used for data between two groups, Friedman test was used for data of each group, and Spearman nonparameter relevant analysis was used for efficacy indexes. Results: (1) All Patients have confirmed diagnosis of hypocvascular liver cancer and got balanced baseline. (2) Lipiodol-filling status:the clinical efficacy and benefit rates of patients from experimental group were higher than that from control group and showed statistically significant difference in 1, 3, 12 months (Z=-2.135, -2.939, -2.686; P=0.034, 0.004, 0.007), but no statistically significant difference in 6 month (Z=-1.170, P=0.242). The status of lipiodol-filling of experimental group (χ2=2.593, P=0.459) was more stable than control group (χ2=10.886, P=0.012). (3) Maximum diameter of the tumor: the clinical efficacy and benefit rates of patients from experimental group were higher than that from control group and showed statistically significant difference in 3, 12 months (Z=-2.734, -2.733; P=0.006, 0.006), but no statistically significant difference in 1,6 month (Z=-1.692, -1.895; P=0.091, 0.058). But neither of two groups showed statistically significant difference in change of maximum diameter of the tumor (χ2=5.500, P=0.139;χ2=6.509, P=0.089). Relation between lipiodol-filling and maximum diameter showed positive correlation in 3 month (r=0.257, P=0.035). (4

  8. Severe complications associated with transcatheter hepatic arterial chemoembolization

    International Nuclear Information System (INIS)

    Transcatheter hepatic arterial chemoembolization (THACE) has been widely used in the treatment of advanced primary hepatic carcinoma (PHC)and metastatic hepatic carcinoma (MHC). Although the incidence of severe complications associated with THACE is unusual (0%-5%), its prognosis is generally worse and mortality is higher than that of postemholization syndrome. Therefore, to minimize the risk associated with THACE has to be achieved through the understanding of these severe complications related to the selection of indication,the use of chemoembolic agents and manipulation ora cathether or guide wire, etc. In this paper, according to the involved anatomic organs, these severe complications are divided into six categories as follows: (1)complications of the liver, including acute hepatic failure, liver infarction (necrosis), liver abcess and liver (or tumor)ruptrure; (2)complications of the celiac artery and its branches, included of iatrogenic dissection, stricture or occlusion, perforation or pseudoaneurysm and multiple intrahepatic aneurysms; (3)complications of intrahepatic biliary system, included of cholecystitis and gallbladder infarction, bile duct necrosis and intrahepatic biloma formation; (4)complications of extrahepatic structures, included of nontarget embolism or infarction of the brain, spinal cord, lung, spleen, gastroduodenum and pancreas; (5)bleeding of upper digestive tract; (6)the orthers. And the incidence, pathogenesis, predisposing factors, clinical and imaging manifestations of these complications are also discussed in detail, it may be of great advantage to its correct diagnosis promptly and appropriate management.

  9. Bronchial artery embolization in the treatment of massive hemoptysis

    International Nuclear Information System (INIS)

    Objective was to evaluate the efficacy of bronchial arteriography and bronchial artery embolization (BAE) in the management of massive hemoptysis in a developing Asian country. A retrospective review was carried out from March 2000 to March 2005 to evaluate the demographics, clinical presentation, radiographic studies, bronchoscopy results, and complications of bronchial arteriography and BAE at a tertiary care hospital in Pakistan. Fourteen patients (9males, 5 females) with a mean age of 49 years underwent bronchial arteriography and BAE for massive hemoptysis. Hemoptysis was caused by bronchiectasis (10 patients), active pulmonary tuberculosis (3 patients), and lung malignancy (one patient). A CT scan of the chest was carried out in 11 patients, which revealed bronchiectasis (8 patients), cavity with infiltrates (3 patients), and mass lesion (one patient). Bronchoscopy was performed in all patients. Bleeding lobe or segment was identified in 12 patients. Bronchial arteriography revealed hypervascularity (13 patients), bronchial artery hypertrophy (5 patients), hypervascularity with shunting (one patient), dense soft tissue staining (7 patients), extravasation of contrast (one patient) pseudoaneurysm (one patient). Bronchial artery embolization was carried out in all patients. Rebleeding occurred within 24 hours in 2 patients who underwent surgery and within one week another 2 patients who were managed with repeat BAE. The complication of embolization occurred in one patient (transverse myelitis). Thirteen patients improved and were discharged home. One patient with terminal lung carcinoma died due to cardiogenic shock secondary to acute myocardial infarction. Bronchial artery embolization is an effective method for management of massive hemoptysis in developing countries and has a low complication rate. (author)

    We present our experience with 105 patients in whom percutaneous transluminal angioplasty was performed in 112 stenosed or occluded supra-aortic arteries. Symtoms of cerebrovascular and/or vertebrobasilar insufficiency were present in 104 of the 105 patients. The angioplasty was successful in 35 stenoses of the internal carotid artery, 2 stenoses of the common carotid artery, 1 stenosis of the external carotid artery, 15 stenoses of the vertebral artery, 3 stenoses of the innominate artery and 44 stenoses of the subclavian artery. There were only 4 minor-complications (2 haematomas, 1 transient ischemic attack, 1 small thrombus of the internal carotid artery which was detected by 111-indium platelet scintigraphy and treated by thrombendarterectomy before the appearance of neurological symptoms). All patients were symptom free after angioplasty. During the observations period of 3 to 109 months (average 58 months) there were only two cases with re-stenosis after subclavian angioplasty. The results of more than 700 personal and international published percutaneous transluminal angioplasties of supra-aortic arteries are presented. The results suggest that angioplasty of supra-aortic arteries is an effective method. On strict definition of the indications, the complication rate for angioplasty of the supra-aortic arteries is not likely to be higher than that for operative treatment. (orig.).

    lesions were 3.15(0-18.9)years.Twenty-seven patients(27/51,52.9%)presented with two or more aneurysmal lesions.The most commonly affected sites were abdominal aorta,pulmonary artery and femoral artery,with a majority of pseudoaneurysms.Swelling and pain in the affected artery area were the major symptoms.Pseudoaneurysms were gengrelly concurrent with other types of vascular involvement.During the onset of aneurysms,erythrocyte sedimentation rate reached (35.2 ±23.4)mm/1 h,C reactive protein levels were (40.8 ±37.9)mg/L,and the BS Current Activity Form 2006 score was (2.04 ±0.97).Large dose of glucocorticoids were administered in 38 patients, and 43 patients were treated with cyclophosphamide.Twenty patients received interventional therapy(graft interposition,graft embolization),8 patients were treated with surgical intervention, and 1 patient had graft interposition with surgical clipping.Four patients died,including 2 patients died with severe hemoptysis,1 patient died with presumed abdominal aneurysm rupture,and the other one for coronary artery rupture.Conclusion Aneurysmal lesions are severe complications in BS patients.BS patients diagnosed with major arterial aneurysms should be further evaluated to detect possible associated vascular involvements or aneurysmal lesions at other sites.We suggest that achieving complete remission of BS and performing surgical or interventional procedures are both important in the treatment of BS patients with aneurysmal lesions.

  14. Superior Mesenteric Artery Syndrome: An Infrequent Complication of Scoliosis Surgery

    Metin Keskin

    2014-01-01

    Full Text Available Superior mesenteric artery syndrome is a rare condition that causes a proximal small intestinal obstruction due to contraction of the angle between the superior mesenteric artery and the aorta. Scoliosis surgery is one of the 15 reasons for superior mesenteric artery syndrome, which can present with acute or chronic manifestations. Although conservative treatment is usually possible, surgical treatment is required in certain cases that cannot be treated using conservative methods. In this paper, we describe a patient who developed superior mesenteric artery syndrome after scoliosis surgery and was treated with duodenojejunostomy due to failure and complications of conservative treatment.

  15. Blood tracer kinetics in the arterial tree.

    Directory of Open Access Journals (Sweden)

    Elias Kellner

    Full Text Available Evaluation of blood supply of different organs relies on labeling blood with a suitable tracer. The tracer kinetics is linear: Tracer concentration at an observation site is a linear response to an input somewhere upstream the arterial flow. The corresponding impulse response functions are currently treated empirically without incorporating the relation to the vascular morphology of an organ. In this work we address this relation for the first time. We demonstrate that the form of the response function in the entire arterial tree is reduced to that of individual vessel segments under approximation of good blood mixing at vessel bifurcations. The resulting expression simplifies significantly when the geometric scaling of the vascular tree is taken into account. This suggests a new way to access the vascular morphology in vivo using experimentally determined response functions. However, it is an ill-posed inverse problem as demonstrated by an example using measured arterial spin labeling in large brain arteries. We further analyze transport in individual vessel segments and demonstrate that experimentally accessible tracer concentration in vessel segments depends on the measurement principle. Explicit expressions for the response functions are obtained for the major middle part of the arterial tree in which the blood flow in individual vessel segments can be treated as laminar. When applied to the analysis of regional cerebral blood flow measurements for which the necessary arterial input is evaluated in the carotid arteries, present theory predicts about 20% underestimation, which is in agreement with recent experimental data.

    Background: The prolonged bed-rest required achieving hemostasis after splanchnic angiography and interventional procedures can be avoided if the upper limb arteries are used. In such procedures, the use of long sheaths capable of reaching the descending aorta may be advantageous. Purpose: To analyze the results of procedures that utilizes an upper-limb-artery approach and long sheaths. Material and Methods: Two hundred forty-two patients with a mean age of 64 years underwent splanchnic angiography and interventional procedures via an upper limb artery using a long sheath (85 cm, 4-French). Repeat examinations were performed on 48 patients and the total number of examinations was 296. The records of these 296 examinations were reviewed and the success rate and complications were evaluated. Results: Overall, 295 of 296 (99.7%) examinations were successful, and one (0.3%) failed. Complications and side effects occurred in six cases (2.0%), a painful sheath manipulation occurred in two examinations (0.7%), and arterial occlusion (including temporary occlusion), hematoma of the puncture site, and pseudoaneurysm occurred in two (0.7%), one (0.3%), and one (0.3%) patient, respectively. Conclusion: The use of a long sheath capable of reaching the descending aorta enables the performance of splanchnic angiography and interventional procedures via the upper limb arteries

    Primary choriocarcinoma of the uterine cervix (PCC) is an extremely rare disease. The conventional treatment of PCC is a combination of hysterectomy and chemotherapy. We present one rare case proved by cervical biopsy. The patient was an 36-year-old Chinese woman with irregular vaginal bleeding for 60 days. A cervical tumoral mass was seen in the pel-vic examination and biopsy revealed active hyperplasia of trophoblastic cell, Because of massive vaginal haemorThage, the patient accepted uterine artery drug pouring and embolism emergently. This management had gained a satisfactory effect. Thus, Uterine artery drug pouring and embolism is one new and effective weapon for PCC, which can preserve the patient's productive abUity.

    Aneurysms in the pediatric population are a rare pathology with specific features which requires a deep knowledge of their pathogenesis for the best therapeutic choice; the authors report their experience with a patient presenting aneurysm of the middle cerebral artery (MCA) associated with proximal stenosis of the vessel. A six-year-old girl came to our observation after sudden onset of headache and left hemiparesis. Angio-MRI and angio-CT scan showed a right MCA dissecting aneurysms associated with proximal stenosis of the vessel. Patient started a therapy with low molecular weight heparin (LMWH), replaced, 15 days later, with acetyl-salicylic acid (ASA). Patient showed a rapid and almost complete neurological recovery, despite several radiological exams confirmed a complete occlusion of the right MCA. As many other authors noted, dissecting aneurysms in the pediatric population are probably due to a defect of the entire arterial wall. Combination of stenosis, turbulence and partial thrombosis of the aneurysm led to a complete occlusion of artery involved, leading to the formation of collateral circles. In our case, complete thrombosis was probably delayed with anticoagulant therapy and the progressive reinforcement of collateral circles lead to the patient's neurological recovery.

    Full Text Available Abstract Background Coronary artery disease is the leading cause of morbidity and mortality in patients with type 2 diabetes. Screening for asymptomatic coronary artery disease with treatment by means of revascularization seems to be an appealing option for prevention. The utility of such a strategy has never been challenged in a randomized trial. Methods/Design In the present study a cohort of diabetic patients without any symptoms and without known coronary artery disease will be screened at two diabetes outpatients services. Those with intermediate or high risk (equal or greater than 10% according to the Italian risk chart will be asked to participate and enrolled. They will be seen and followed in order to provide the best adherence to medical therapy. Half of the patients will be randomized to undergo an exercise tolerance testing while the other group will continue to be regularly seen at diabetes outpatients services. Best medical/behavioral therapy will be offered to both groups. Those patients with a positive exercise tolerance testing will be studied by coronary angiography and treated according to the severity of coronary lesions by percutaneous stenting or surgery. The objective of the study is to evaluate the efficacy of the screening strategy aimed at revascularization. A cost-effectiveness analysis will be performed at the end of the follow up. Discussion The study will provide useful information about prevention and treatment of diabetic patients at high risk of coronary events. It will be made clearer if detection of silent coronary artery disease has to be recommended and followed by treatment. Given the simplicity of the study protocol, it will be easily transferable to the real world. Trial registration (ClinicalTrials.gov: NCT00547872

  2. Transcatheter Splenic Artery Occlusion for Treatment of Splenic Artery Steal Syndrome After Orthotopic Liver Transplantation

    International Nuclear Information System (INIS)

    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

    Arteriopathy restricted to the popliteal artery, except in cases of atheroma, must indicate three of four unusual diagnoses: the trapped popliteal artery and the dessicating haematoma are anatomo-clinical entities that have been identified only relatively recently. The popliteal artery may be trapped by the medial gastrocnomius muscle, round the tendon of which the artery passes (totally or partially). This results in compression of the artery and eventually in thrombosis. Clinically, intermittent claudication is seen that may deteriorate and lead to gangrene of the toes. Arteriography makes it possible to diagnose the condition as the condition as the artery is considerably displaced inwards. Surgical correction is simple: sectioning of the tendon and repositioning of the artery. Dessicating haematoma of the popliteal artery is due essentially to atheroma, associated with medianecrosis. A "egg-timer" stenosis is found by arteriography and this condition also progresses towards thrombosis. Arterial restoration is called for, usually by bridging. PMID:1230799

    Background:De novo aneurysms after internal carotid artery(ICA)occlusion occur in the contralateral ICA or anterior communicating artery. Hemodynamic changes with increased blood flow to the contralateral carotid circulation were considered the main factor for the formation of these aneurysms. We report a rare case of ruptured ICA aneurysm associated with ipsilateral ICA occlusion treated with coil embolization via the vertebrobasilar and posterior communicating arteries. Case Presentation:An 82-year-old woman presented with sudden-onset disturbance of consciousness at our outpatient clinic and went into cardiopulmonary arrest. Computed tomography(CT)performed after cardiopulmonary resuscitation revealed diffuse subarachnoid hemorrhage. Three-dimensional CT angiography revealed a right ICA aneurysm associated with the ipsilateral ICA occlusion. Considering that the patient showed clinical improvement with the critical care for neurogenic pulmonary edema, the aneurysm was treated with endovascular coil embolization via the posterior communicating artery. With this technique, complete obliteration was attained without perioperative complication. Conclusion:Endovascular coil embolization via the posterior communicating artery was proven effective as a treatment method for ruptured ICA aneurysms with ipsilateral ICA occlusion. Hemodynamic stress due to increased blood flow in the posterior communicating artery may play an important role in the growth and rupture of ICA aneurysms. PMID:27605482

    We present a patient with an acutely ruptured, wide-necked aneurysm of the left posterior cerebral artery (PCA) treated with Guglielmi detachable coils using the remodeling technique. Since the left vertebral artery was compressed due to a tumor in the cerebellopontine angle and the right vertebral artery was hypoplastic, we used a carotid artery approach via a persistent primitive trigeminal artery (PPTA) to selectively catheterize the aneurysm. The aneurysm was occluded completely. To our knowledge this is the first case of a wide-necked PCA aneurysm treated via a PPTA and using the remodeling technique. In patients with hypoplastic vertebral arteries and a PPTA, this approach may represent an alternative for selective embolization of posterior circulation aneurysms not amenable to the conventional approach.

    Full Text Available Objective To discuss the individualized management strategy for intracranial vertebral artery dissecting aneurysms. Methods Eighteen patients with intracranial vertebral artery dissecting aneurysms were treated with different surgical methods. Results Eighteen patients underwent different surgical treatment. Five patients underwent complete occlusion of the aneurysm and parent artery by coiling, 5 were treated by stent -assisted coiling (3 densely packed coiling and 2 non-densely packed coiling, 4 underwent stent-only therapy and 3 of them presented hemodynamic improvement after surgery, 3 were treated by direct surgical clipping, and 1 underwent occipital artery-posterior inferior cerebellar artery bypass. Two aneurysms ruptured immaturely, in which one patient died on the third day after operation and one patient occurred moderate disablity. Only 1 patient who underwent complete occlusion of aneurysm and parent artery presented temporarily ischemic symptoms. No adverse effects were seen in other patients. Seventeen patients were followed up for 1 month to 3 years, and all the aneurysms were stable. Conclusion There are many kinds of therapeutic methods for intracranial vertebral artery dissecting aneurysms. The patients should be treated according to several factors such as the clinical manifestations, aneurysm configuration, and relationship with the posterior inferior cerebellar artery. The treatment should be individualized.

Methods Clinical data of 1 patient with pseudoaneurysm rupture hemorrhage patient af-ter pancreaticoduodenectomy for Vater's ampullary carcinoma was retrospectively analyzed, and relevant literature was also re-viewed. Results After pancreaticoduodenectomy (3 weeks), the patient's condition was complicated with the burst of the splenic artery pseudoaneurysm rupture, and after celiac artery spring bolt and gelatin sponge embolization surgery, postopera-tive hemorrhagic shock, acute liver and kidney dysfunction occurred, and the patient was admitted to our hospital when the circulatory function became stable. Upon admission he developed hypoalbuminemia, multiple liver abscess, abdominal abscess and empyema and after repeated abscess drainage catheter, intravenous nutritional support, broad-spectrum antibiotic therapy, the patient still had persistent fever, and the relapses made the condition worse. Total parenteral nutrition support was suspen-ded and antibiotics and many other medications, endoscopic gastric jejunostomy enteral nutrition support were given, with the secondary psychological counseling and physical exercise, and the condition gradually improved, the patient was able get out of the bed after 2 months. Sleep, diet and mental condition also returned to normal and 3 months later he was discharged. Conclusion Postoperative treatment of critically ill patients should not over-rely on antibiotics and total parenteral nutrition. Attention should be paid promptly to minimally invasive abscess drainage, and enteral nutrition and psychological counseling should be strengthened and the use of antibiotics and other drugs be limited, all of which may be helpful in the rehabilitation of critically ill patients.%目的:总结探讨胰十二指肠切除术后并发假性动脉瘤破裂出血的诊疗新

    Compared to lower limb arterial diseases, upper limb arterial diseases look rare, heterogeneous with various etiologies and a rather vague clinical picture, but with a negligible risk of amputation. Almost all types of arterial diseases can be present in the upper limb, but the anatomical and hemodynamic conditions particular to the upper limb often confuse the issue. Thus, atherosclerosis affects mainly the subclavian artery in its proximal segment where the potential of collateral pathway is high making the symptomatic forms not very frequent whereas the prevalence of subclavian artery stenosis or occlusion is relatively high. The clinical examination and the etiologies are discussed according to the clinical, anatomical and hemodynamic context.

    2011-06-01

    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.

    Visceral artery aneurysms(VAA) include splanchnic and renal artery aneurysms. They represent a rare clinical entity, although their detection is rising due to an increased use of cross-sectional imaging. Rupture is the most devastating complication, and is associated with a high morbidity and mortality. In addition, increased percutaneous endovascular interventions have raised the incidence of iatrogenic visceral artery pseudoaneurysms(VAPAs). For this reason, elective repair is preferable in the appropriately chosen patient. Controversy still exists regarding their treatment. Over the past decade, there has been steady increase in the utilization of minimally invasive, non-operative interventions, for vascular aneurysmal disease. All VAAs and VAPAs can technically be fixed by endovascular techniques but that does not mean they should. These catheter-based techniques constitute an excellent approach in the elective setting. However, in the emergent setting it may carry a higher morbidity and mortality. The decision for intervention has to take into account the size and the natural history of the lesion, the risk of rupture, which is high during pregnancy, and the relative risk of surgical or radiological intervention. For splanchnic artery aneurysms, we should recognize that we are not, in reality, well informed about their natural history. For most asymptomatic aneurysms, expectant treatment is acceptable. For large, symptomatic or aneurysms with a high risk of rupture, endovascular treatment has become the firstline therapy. Treatment of VAPAs is always mandatory because of the high risk of rupture. We present our point of view on interventional radiology in the splanchnic arteries, focusing on what has been achieved and the remaining challenges.

    The subscapular artery arises from the third part of the axillary artery and gives off the circumflex scapular and the thoracodorsal arteries. Although anatomical variations of the axillary artery are very common, the existence of a unilateral accessory thoracodorsal artery has been described in the literature only once. There are no reports of bilateral accessory thoracodorsal artery, in the literature. In the present study, a bilateral accessory thoracodorsal artery, originating on either side of the third part of the axillary artery, is described in a 68-year-old female cadaver. All the other branches of the axillary artery had a typical origin, course, distribution and termination. This extremely rare anatomical variation apart from the anatomical importance also has clinical significance for surgeons in this area. Especially, during the dissection or mobilization of the latissimus dorsi that is partly used for coverage problems in many regions of the body and also in dynamic cardiomyoplasty, any iatrogenic injury of this accessory artery may result in ischemia and functional loss of the graft.

    Renal artery stenosis can be diagnosed during pregnancy and treated at the same time. A 30-year-old woman had a sudden, severe but asymptomatic hypertensive crisis at 21 weeks of gestation. The diagnosis of renal artery stenosis suspected on Doppler ultrasonography was confirmed and treated by renal angioplasty, which reduced her blood pressure. At 27 weeks of gestation, her blood pressure increased again, associated with significant proteinuria, suggesting pre-eclampsia. A cesarean section was performed giving birth to a healthy 940-g child. Renal artery stenosis should be considered when sudden and early-onset hypertension appears during pregnancy.

    Hemobilia is an uncommon and potential life-threatening condition mainly due to hepato-biliary tree traumatic or iatrogenic injuries. Spontaneously ruptured aneurysm of the hepatic artery is seldom described. We report the case of an 89-year-old woman presenting with abdominal pain, jaundice and gastrointestinal bleeding, whose ultrasound and computed tomography revealed a non-traumatic, spontaneous aneurysm of the right hepatic artery. The oeso-gastro-duodenoscopy and colonoscopy did not reveal any bleeding at the ampulla of Vater, nor anywhere else. Selective angiography confirmed the diagnosis of hepatic artery aneurysm and revealed a full hepatic artery originating from the superior mesenteric artery. The patient was successfully treated by selective embolization of microcoils. We discuss the etiologies of hemobilia and its treatment with selective embolization, which remains favored over surgical treatment. Although aneurysm of the hepatic artery is rare, especially without trauma, a high index of suspicion is needed in order to ensure appropriate treatment. PMID:27358680

    AIM: To investigate the poor prognosis of HCC with PVTT, we evaluated the efficacy by a new combination chemotherapy for advanced hepatocellular carcinoma (HCC) with portal vein tumor thrombus (PVTT).METHODS: From 2002 to 2007, a total of 10 consecutive patients with Stage IVA HCC accompanied by PVTT were studied prospectively to examine the efficacy of treatment by intra-arterial infusion of a chemotherapeutic agents consisting of etoposide, carboplatin, epirubicin and pharmacokinetic modulating chemotherapy by 5-FU and enteric-coated tegafur/uracil.RESULTS: The mean course of chemotherapy was 14.4 (range, 9-21) mo. One patient showed complete response (CR) with disappearance of HCC and PVTT after treatment, and the two patients showed partialresponse (PR), response rate (CR + PR/All cases 30%).The median survival time after the therapy was 457.2 d. The one-year survival rate was 70%. Adverse reactions were tolerable.CONCLUSION: Although the prognosis of most patients with Stage IVA HCC by PVTT is poor, our combination chemotherapy may induces long-term survival and is an effective treatment and produced anti-tumor activity with tolerable adverse effects in patients for advanced Stage IVA HCC accompanied by PVTT.

    Coronary artery aneurysms remain a life-threatening complication of Kawasaki disease (KD), the most common form of pediatric acquired heart disease in developed countries (1). Potentially life-threatening coronary artery aneurysms (CAA) develop in 25% of untreated children and 5% of children treated with high dose intravenous immunoglobulin during the acute phase of the self-limited vasculitis (2). Non-coronary artery aneurysms (NCAA) in extra-parenchymal, muscular arteries occur in a minorit...

    We report a rare case of aneurysm of splenic artery arising anomalously from the superior mesenteric artery (SMA). The aneurysm was treated successfully by coil embolization of the splenic artery distal to aneurysm and then deploying a stent graft in the SMA. A combination of stent graft and coil embolization for the treatment of aberrant splenic artery aneurysm has been reported only once. We describe the imaging findings and the endovascular procedure in this patient.

    Trapped popliteal artery syndrome is relatively uncommon: the literature reports some 60 cases. The clinical picture is linked to compression of the popliteal artery by the gastrocnemius as it contracts, thus distorting the arterial route. The result is an interruption in the blood flow distally to the area involved due to stenosis of the blood vessel that is at first functional but becomes organic. PMID:3808379

    Full Text Available Celiac artery compression syndrome is a rare disorder characterized by episodic abdominal pain and weight loss. It is the result of external compression of celiac artery by the median arcuate ligament. We present a case of celiac artery compression syndrome in a 57-year-old male with severe postprandial abdominal pain and 30-pound weight loss. The patient eventually responded well to surgical division of the median arcuate ligament by laparoscopy.

    of healthy monozygotic and dizygotic twins were examined using digital fundus photography and visual assessment of grayscale fundus photographs and color transparencies to detect the presence of cilioretinal arteries. RESULTS: Cilioretinal arteries were present in 45.1% of participants and 28.8% of eyes....... The majority of cilioretinal arteries, 88.2%, were located temporally, and 11.8% were located nasally. Monozygotic twins had higher concordance rates for cilioretinal arteries than dizygotic twins. Tetrachoric correlations and Mantel-Haenszel odds ratios demonstrated statistically significant evidence...

  20. A Vertebral Artery Dissection with Basilar Artery Occlusion in a Child

    Full Text Available This paper presents the case report of an 11-year-old boy with an acute dissection with thrombosis of the left vertebral artery and thrombosis of the basilar artery. The patient was treated with acute systemic thrombolysis, followed by intra-arterial thrombolysis, without any clinical improvement, showing left hemiplegia, bilateral clonus, hyperreflexia, and impaired consciousness. MRI indicated persistent thrombosis of the arteria basilaris with edema and ischemia of the right brainstem. Heparinization for 72 hours, followed by a two-week LMWH treatment and subsequent oral warfarin therapy, resulted in a lasting improvement of the symptoms. Vertebral artery dissection after minor trauma is rare in children. While acute basilar artery occlusion as a complication is even more infrequent, it is potentially fatal, which means that prompt diagnosis and treatment are imperative. The lack of class I recommendation guidelines for children regarding treatment of vertebral artery dissection and basilar artery occlusion means that initial and follow-up management both require a multidisciplinary approach to coordinate emergency, critical care, interventional radiology, and child neurology services.
