Retroperitoneal fibrosis or Ormond’s disease is an uncommon process characterized by fibrous tissue proliferation in the retroperitoneum, usually involving the aorta, inferior vena cava and iliac vessels. Obstructive hydronephrosis is often observed due to ureteral entrapment. This report presents a case of the peripancreatic location of the disease. The role of CT and MRI in establishing diagnosis of retroperitoneal fibrosis in an atypical site is discussed. A 52-year-old woman with Hashimoto’s thyroiditis was admitted to hospital because of pain suggesting renal colic. The patient was subjected to ultrasound, CT, and MRI which did not confirm urolithiasis but revealed pancreatic infiltration. Partial pancreatectomy, left-sided adrenalectomy and splenectomy were performed. Retroperitoneal fibrosis was diagnosed in the histopathological examination. A few weeks after surgery, a complication such as pancreatitis developed. Repeat CT confirmed it and showed right hydronephrosis secondary to ureteral involvement by a mass adjacent to the common iliac artery (defined as a typical manifestation of retroperitoneal fibrosis). Nephrostomy and conservative treatment improved the clinical state of the patient. No progression of the process was observed in the follow-up examinations. Atypical retroperitoneal fibrosis remains a diagnostic challenge. Imaging techniques CT and MRI are useful tools for evaluating the extent of Ormond’s disease. An unusual distribution of the process (e.g. peripancreatic location reported in this study) requires histopathological assessment to establish the final diagnosis

Full Text Available Introduction. Adrenal hemangioma is a rare disease, with only some 60 cases reported previously. Due to the difficulty of the preoperative diagnosis of adrenal hemangioma, almost all of the cases were diagnosed by a histopathological analysis of surgical specimens. Case Presentation. A 52-year-old man was referred to our department for further examination of his left retroperitoneal tumor. He had received hemodialysis due to chronic renal failure resulting from membranous nephropathy. Computed tomography revealed a mass around his left hilum. Magnetic resonance imaging (MRI and positron-emission tomography (PET-CT were unable to confirm or deny malignancy, and tumor markers, including CEA and CA19-9, showed slight elevation. His tumor grew from 38 mm to 54 mm in diameter in 7 months of follow-up. We therefore planned retroperitoneal tumor resection with left nephrectomy. Histopathologically, hyperplastic small vessels with hemorrhaging and denaturation were seen. The endothelial cells showed no variants or division of the nucleus. Based on this diagnosis, no further therapy was performed. He has had no recurrence in the eight months since the surgery. Conclusion. We herein report a rare case of adrenal hemangioma.

Este trabajo describe el cuadro clínico, el diagnóstico y el tratamiento médico-quirúrgico de esta paciente. Se analiza cómo la elaboración de un diagnóstico certero requiere de un análisis adecuado de los antecedentes epidemiológicos, las manifestaciones clínicas, los estudios de imágenes y las pruebas de laboratorio, ya que el conjunto de estos datos confirman el caso.Hydatid disease in a worldwide zoonosis. It is caused by a parasitic platyhelminth of the genus Echinococcus. We present a patient with a fluctuating lumbar tumor in the retroperitoneal space, secondary to a hepatic cyst. The initial diagnosis was made by identification of rostellar hooks from protoscoleces in the fluid aspirated from the abscess. We herein describe the clinical manifestations, diagnosis and medical and surgical treatment of this unusual case and conclude that the development of an accurate diagnosis required a proper analysis of the patient's epidemiological history, clinical manifestations, imaging studies and laboratory tests. A multidisciplinary approach and differential diagnosis is paramount to be able to establish a cause of the disease to deliver appropriate treatment.

Full Text Available Schwannomas are usually benign rare tumors that originating from Schwann cells of peripheral nerve sheaths. Presentation is generally varied and changed in a non-specific range from abdominal mass, flank pain to incidental findings. Herein we report 2 cases of retroperitoneal giant schwannomas with different clinical presentations, of whom one presented with vague abdominal pain, palpable abdominal mass for 4 years, swelling and bilateral hydronephrosis that caused by giant abdominal mass; the other one presented with right flank pain, rectal hemorrhage and lower extremities edema. Two patients were treated by complete surgical excision of masses. The histological and immunohistochemical diagnosis was reported as benign schwannoma. Both of patients are doing well and had no recurrence in 9 years and 28 months follow-up, respectively.

Idiopathic Retroperitoneal Hematoma

Full Text Available A 34-year-old female presented with sudden onset of severe abdominal pain in a flank distribution. A large mass was palpable in the right upper quadrant on physical examination. Abdominal contrast-enhanced computed tomography showed a well-defined, right-sided, retroperitoneal cystic lesion located between the abdominal aorta and the inferior vena cava (IVC. The tumor size was 55 × 58 mm, and it compressed the gallbladder and the duodenum. Upper gastrointestinal radiography revealed a stricture of the second portion of the duodenum by the tumor. T2-weighted magnetic resonance imaging showed that the whole part was hyperintense with hypointense rims, but the inner was partially hypointense. Based on the radiological findings, the preoperative differential diagnosis included retroperitoneal teratoma, Schwannoma, abscess, and primary retroperitoneal tumor. On laparotomy, the tumor was located in the right retroperitoneal cavity. Kocher maneuver and medial visceral rotation, which consists of medial reflection of the upper part of right colon and duodenum by incising their lateral peritoneal attachments, were performed. Although a slight adhesion to the IVC was detected, the tumor was removed safely. Thin-section histopathology examination detected neither tumor tissues nor any tissues such as adrenal gland, ovarian tissue, or endometrial implants. The final pathological diagnosis was idiopathic retroperitoneal hematoma; the origin of the bleeding was unclear. The patient was discharged without any complication 5 days after the operation.

Ventriculoperitoneal shunt (VPS) is a common procedure in daily neurosurgical practice. According to some reports, the rate of intracerebral hemorrhage secondary to VPS in patients with no bleeding tendency can be 43.1%; however, symptomatic intracerebral hemorrhage (SICH) secondary to VPS is rare with only sporadic cases reported in adults. To further elucidate the characteristics, mechanism, management, and prognosis of SICH secondary to VPS, we performed a retrospective study in our institution and a systematic review of the literature. A retrospective review of the medical records of patients admitted for VPS was performed. We also performed a systematic PubMed search of published studies. Of 5 patients identified at our institution, 3 experienced a favorable recovery. Including our case series, there were 16 (8 female) patients. The time interval from the termination of VPS procedure to SICH was 4 hours to 15 days. All but 1 patient experienced intracerebral hemorrhage adjacent to cannulation. Of 11 patients in whom a Glasgow Outcome Scale score could be obtained, the score was 5 in 4 patients, 4 in 1 patient, 3 in 1 patient, and 1 in 5 patients. SICH is a rare complication after VPS in adults without bleeding tendency. The mechanism is obscure, management is challenging, and prognosis is dismal. Future prospective study is anticipated.

Kasotakis, George

2014-02-01

The retroperitoneum is rich in vascular structures and can harbor large hematomas, traumatic or spontaneous. The management of retroperitoneal hematomas depends on the mechanism of injury and whether they are pulsatile/expanding. Rectus sheath hematomas are uncommon abdominal wall hematomas secondary to trauma to the epigastric arteries of the rectus muscle. The common risk factors include anticoagulation, strenuous exercise, coughing, coagulation disorders, and invasive procedures on/through the abdominal wall. The management is largely supportive, with the reversal of anticoagulation and transfusions; angioembolization may be necessary. Copyright © 2014 Elsevier Inc. All rights reserved.

IgG4-related retroperitoneal fibrosis: a newly characterized disease.

2016-11-01

Retroperitoneal fibrosis (RPF) is a rare disease characterized by chronic, nonspecific inflammatory and sclerotic or fibrotic tissue in the periaortic or periiliac retroperitoneum that encases adjacent structures. There will be a series of clinical manifestations once the proliferated fibrous tissues encase the abdominal aorta, iliac arteries and urinary duct. RPF is generally divided into two types: idiopathic retroperitoneal fibrosis (IRPF) without identified pathogenesis, making up about two-thirds of cases, and secondary retroperitoneal fibrosis. Recent studies on Immunoglobulin G4-related disease (IgG4-RD) reveal that abundant infiltration of IgG4 positive plasma cells is found in biopsies on the mass of RPF of some IRPF patients, which is identified as one spectrum of IgG4-RD and is named IgG4-related RPF. IgG4-related RPF is often misdiagnosed as retroperitoneal visceral malignancy and is treated with surgery. In addition, because of its good response to glucocorticoid, early detection and treatment is important. We review the definition, epidemiology, clinical features, diagnostic criteria, treatment and prognosis of IgG4-related RPF in this article to raise awareness of this newly characterized disease. © 2016 Asia Pacific League of Associations for Rheumatology and John Wiley & Sons Australia, Ltd.

Retroperitoneal ganglioneuroma in a young bodybuilder

Durczynski, A.; Szymanski, D.; Hogendorf, P.; Strzelczyk, J.; Sporny, S.

2010-01-01

Background: Anabolic steroid intake is common among bodybuilders, although it is associated with a number of adverse effects, including tumorgenesis. Case Report: We describe the case of 24-year-old male athletic bodybuilder (weight 110 kg, height 179, BMI 34 kg/m 2 ) admitted to our department with diffused, intermittent, abdominal pain of 4 months duration. The patient had a history of long-term abuse of large doses of anabolic steroids of unknown origin. Computed tomography scans revealed a large, 140 x 100 mm, well-demarcated tumor, located between the left kidney, pancreas and spleen, presumably originating from the left kidney or adrenal gland. The tumor was proven to be hormonally inactive. Retroperitoneal tumor excision was performed with surrounding organs left intact. A final histopathologic examination revealed a well-differentiated 16 cm ganglioneuroma. Despite the rarity of its occurrence, ganglioneuromas must be considered in the differential diagnosis of retroperitoneal tumors. Conclusions: This unique finding raises questions concerning potential development of ganglioneuroma secondary to steroid abuse among bodybuilders. Bodybuilders should be made aware of the serious medical risks of steroid abuse. (authors)

Gigantic retroperitoneal leiomyosarcoma - case report

Retroperitoneal leiomyosarcomas are very rare malignant neoplasms. They are built up of smooth muscle cells. They can be found beyond the retroperitoneal space in the uterus, the stomach, the intestines, the blood vessel walls and the skin. This type of tumour grows slowly and gives no characteristic clinical symptoms. This results in late diagnosis, when they grow to a huge size. Retroperitoneal leiomyosarcomas are most frequently described in the literature in the fifth or sixth decade of life. There are no biochemical markers which could suggest the development of leiomyosarcoma. The basic diagnostic examination includes: ultrasound and computer tomography of the abdomen. The fundamental treatment of retroperitoneal leiomyosarcomas consists in aggressive surgical treatment - complete tumour resection. Large size of the tumour can make it difficult to perform radical surgery. In the case presented in this report, our team managed to remove a retroperitoneal leiomyosarcoma completely despite its huge mass and size (300 x 200 mm). Data from the literature indicate that a complete resection of the tumour is the most significant prognostic factor in the case of patients with retroperitoneal leiomyosarcoma. The efficacy of radiotherapy and chemotherapy has not been proved. The other unfavourable prognostic factor in the course of sarcomas is the age of the patient, below 50 years old. The patient presented in the report is a 31-year-old woman, which is associated with a worse prognosis. According to some authors, the size of the tumour is not significant for the fast recurrence of the disease, whereas others state that it is. The case was presented because of such a huge leiomyosarcoma being rarely found in the retroperitoneal space, the age of the patient and the asymptomatic course of the disease. (authors)

A 50-year-old Chinese man was found by ultrasound and computed tomography to have a retroperitoneal mass in the right upper quadrant of the abdomen. At operation, a hemorrhagic cyst was detected at the upper pole of the right kidney adjacent to the adrenal gland. Microscopic examination revealed that the cyst wall was composed of granulomatous tissue loaded with eggs and cross-sections of parasites, identified as Dioctophyma renale. The eggs were characterized by a birefringent striated double wall. The presence of cross sections of adult worms of D. renale in human tissue has not been previously described. Another unique feature of this case was that the right kidney was intact, as examined grossly at laparotomy and by intravenous pyelography. Eggs were not detected in the urine.

Full Text Available Soft tissue sarcomas represent less than 1% of all human neoplasms. One-third of malignant tumors that arise in the retroperitoneum are sarcomas and liposarcoma is the most common retroperitoneal sarcoma and is known to grow to giant sizes, slow progress and few late symptoms. We report the case of a 40 year old woman with a giant retroperitoneal liposarcoma. A laparotomy was performed and a multilobulated tumor of 20 centimeters of diameter arising from retroperitoneum. The histological features were suggestive of pleomorphic liposarcoma weighing 8.5 Kilograms

Does negative retroperitoneal CT in adolescents with paratesticular rhabdomyosarcoma preclude the need of retroperitoneal lymph node dissection?

We report on a 16-year-old male with paratesticular rhabdomyosarcoma who underwent retroperitoneal lymph node dissection due to a stage I tumor (normal retroperitoneal computed tomography). The surgical finding was three enlarged nodes, positive for metastatic disease. Patient was referred to adjuvant chemotherapy. This case suggests that the Intergroup Rhabdomyosarcoma Study Group IV protocol is subject to questions regarding adolescents with paratesticular rhabdomyosarcoma, and that negative retroperitoneal CT does not preclude the need of lymph node dissection.

Extrahepatic biliary atresia (EHBA) is a rare disease characterized by progressive and obliterative cholangiopathy in infants and is one of the major causes of secondary vitamin K deficiency bleeding (VKDB) due to cholestasis-induced fat malabsorption. Breast feeding increases the tendency of bleeding in EHBA patients because breast milk contains low amounts of vitamin K. A 2-month-old female infant unexpectedly died, with symptoms of vomiting and jaundice prior to death. She had been born by uncomplicated vaginal delivery and exhibited normal growth and development with breastfeeding. There was no history of trauma. She received vitamin K prophylaxis orally. In an emergency hospital, a CT scan showed a right intracranial hematoma and mass effect with midline shift to the left. In the postmortem examination, severe atresia was observed in the whole extrahepatic bile duct. Histologically, cholestasis, periductal fibrosis, and distorted bile ductules were noted. The gallbladder was not identified. A subdural hematoma and cerebellar tonsillar herniation were found; however, no traumatic injury in any part of the body was observed. Together, these findings suggest that the subdural hemorrhage was caused by secondary vitamin K deficiency resulting from a combination of cholestasis-induced fat malabsorption and breastfeeding. Subdural hemorrhage by secondary VKDB sometimes occurs even when vitamin K prophylaxis is continued. This case demonstrated that intrinsic factors, such as secondary VKDB (e.g., EHBA, neonatal hepatitis, chronic diarrhea), should also be considered in infant autopsy cases presenting with subdural hemorrhage.

In hemodynamically unstable patients, the management of retroperitoneal vascular trauma is both difficult and challenging. Endovascular techniques have become an alternative to surgery in several trauma centers. Between 2004 and 2006, 16 patients (nine men, mean age: 46 years, range: 19-79 years) with retroperitoneal vascular trauma and hemodynamic instability were treated using an endovascular approach. The mean injury severity score was 30.7 ± 13.1. Mean systolic blood pressure and the shock index were 74 mm Hg and 1.9, respectively. Vasopressor drugs were required in 68.7% of cases (n = 11). Injuries were attributable to road traffic accidents (n = 15) and falls (n = 1). The hemorrhage sites included the internal iliac artery or its branches (n = 12) with bilateral injury in one case, renal artery (n = 2), abdominal aorta (n = 1), and lumbar artery (n = 1). In all, 14 coil embolizations and three stent-grafts were implanted. The technical success rate was 75%, as early re-embolization was necessary in one case and three patients died during the perioperative period. Six patients died during the period of hospitalization (37.5%). No surgical conversion or major morbidity was reported. In comparison with particulates, coil ± stent-graft may provide similar efficacy with regard to survival, and thus may be a valuable solution when particulate embolization is not available or feasible.

Xu Yufeng; Wang Jichen; Peng Yun; Zeng Jinjin

2010-01-01

Primary retroperitoneal neoplasms are uncommon in children. Retroperitoneal neoplasms are either mesodermal, neurogenic, germ cell ectodermal or lymphatic in origin. In general, primary retroperitoneal neoplasms in children have different spectrum and prevalence compared to those in adults. Neuroblastoma, rhabdomyosarcoma, benign teratoma and lymphoma are the common retroperitoneal neoplasms. In this review, the clinical and CT futures of common retroperitoneal neoplasms in children are described. Coarse, amorphous, and mottled calcification are very common in neuroblastoma. Paraganglioma tends to show marked and early enhancement and may present with clinical symptoms associated with the excess catecholamine. Sarcomas are often very large and have heterogeneous appearance. Imaging cannot be reliably used to identify the type of retroperitoneal sarcomas due to overlapped radiographic features. In children, lipoblastoma is the most common lipomatous tumor in the retroperitoneum. The percentage of visible fat in tumor varies depending on the cellular composition of the lesion. The CT characteristics of teratoma are quite variable, which may be cystic, solid, on a combination of both. Typically teratoma appears as a large complex mass containing fluid, fat, fat-fluid level, and calcifications. Lymphoma is often homogeneous on both enhanced and unenhanced CT scans. Necrosis and calcification are rare on CT. In conclusion, making a final histological diagnosis of retroperitoneal tumor base on CT features is not often possible; however, CT can help to develop a differential diagnosis and determine the size and extent of the retroperitoneal neoplasms.

Objective: To analyze CT manifestation of retroperitoneal gigantic liposaxcoma and to improve the image understanding. Methods: Five cases of retroperitoneal gigantic liposarcoma confirmed by surgery and pathology in our hospital were collected. Plain and enhanced CT scan were performed. Results: Of five cases, one was substantive, two was pseudocyst and two was mixed tumor. Several patterns of enhancement such as strip, floccule, irregular patchy or nodular enhancement were revealed inside the lesions on enhanced CT scan. And strip-form of high density enhancement was a typical type. Conclusion: CT examination could determine the tumor's location, size and density, together with the relationship to adjacent organizations CT scan is an important method in diagnosing retroperitoneal gigantic liposarcoma.

2015-01-01

Full Text Available Introduction. Pulmonary hemorrhage secondary to disseminated strongyloidiasis is an unusual, well-recognized entity in immunocompromised patients with autoimmune disease, which is associated with the hyperinfection syndrome, sepsis, and a high mortality rate. Case Presentation. We present a case of a 44-year-old Mexican woman with systemic lupus erythematosus and acute bacterial meningitis who developed pulmonary hemorrhage with acute respiratory failure requiring mechanical ventilation, treated with broad spectrum systemic antibiotics and high dose methylprednisolone, who subsequently developed a characteristic purpuric skin eruption and septic shock and died two days later of refractory hypoxemia caused by massive pulmonary bleeding. The postmortem examination reports filariform larvae of S. stercolaris in lung, skin, and other organs. Conclusion. This case highlights the importance of considering disseminated strongyloidiasis in the differential diagnosis of diffuse alveolar hemorrhage in systemic lupus erythematosus, and screening for S. stercolaris infection before initiation of immunosuppressive therapy should be considered, especially in endemic areas. Disseminated strongyloidiasis has a high mortality rate, explained in part by absence of clinical suspicion.

The aim of this study was to evaluate the surgical outcomes of a modified approach in the management of thick submacular hemorrhage in patients with wet age-related macular degeneration. This was a retrospective study. A retrospective chart review was performed on 10 eyes of 10 patients with submacular hemorrhage secondary to wet age-related macular degeneration treated with 23-gauge pars plana vitrectomy, followed by submacular injection of recombinant tissue plasminogen activator (12.5 μg/0.1 mL), bevacizumab (2.5 mg/0.1 mL), and air (0.3 mL). Gas tamponade was given with 20% SF6 and postoperative propped-up positioning. Patients were evaluated for displacement of hemorrhage, preoperative and postoperative best-corrected visual acuity, occurrence of intraoperative and postoperative complications, and recurrence of hemorrhage. All patients were followed up for 6 months. Displacement of the submacular bleed was achieved in all cases. Improvement of best-corrected visual acuity was seen in 8 of 10 patients. Rebleed was seen in 2 eyes that were retreated with intravitreal injection of recombinant tissue plasminogen activator, bevacizumab, and 20% SF6 gas. This modified technique aids in the effective displacement of thick submacular hemorrhage with simultaneous treatment of the underlying choroidal neovascular membrane, which halts the disease progression resulting in significant improvement of visual acuity.

Abstract Rationale: Hydronephrosis caused by retroperitoneal hematoma after a seatbelt injury is a unique clinical entity. Patient concerns: A 21-year-old man, who had been wearing a seatbelt, was brought to our hospital after a motor vehicle collision, complaining of abdominal pain. Computed tomography (CT) revealed retroperitoneal hematoma in the upper pelvic region. Since he was hemodynamically stable throughout admission, he was managed conservatively. Seventeen days after initial discharge, the patient revisited our emergency department due to right back pain. Diagnoses: CT scans indicated retroperitoneal hematoma growth resulting in hydronephrosis of the right kidney. Interventions: Laparoscopic drainage of the retroperitoneal hematoma was successfully performed. Outcomes: His symptoms resolved after the surgery. Follow-up CT scans three months later demonstrated complete resolution of the hydronephrosis and retroperitoneal hematoma. Lessons: Our case highlights a patient with delayed hydronephrosis because of retroperitoneal hematoma expansion after a seatbelt injury. PMID:29879068

Diseases of the retroperitoneal space in the dog and cat

The retroperitoneal space (RPS) is an anatomical area bounded dorsally by the sublumbar musculature and ventrally by the peritoneal surface of the abdomen. The RPS communicates with the pelvic space and mediastinum and is subject to primary diseases of the RPS connective tissue and to extension of disease from organs lying within or adjacent to it. Primary diseases include retroperitonitis, pneumoretroperitoneum, non-neoplastic retroperitoneal space-occupying lesions, and primary neoplasms of the RPS. Primary diseases of kidneys, ureters, adrenal glands or retroperitoneal lymph nodes may extend into the RPS, and the RPS may be the site of metastatic neoplastic disease. Clinical signs suggestive of retroperitoneal disease include lumbar pain, pyrexia, lethargy, and signs referable to organs within the RPS

Renal angiomyolipoma is a benign tumor formed by smooth muscle, adipose tissue and blood vessels. It is commonly found incidentally and its clinical manifestations are pain and abdominal mass or spontaneous tumor rupture with retroperitoneal bleeding. The clinical presentation of a hemorrhagic shock secondary to a retroperitoneal hematoma is uncommon. We report a 40 year-old male who presented to the emergency room with lumbar pain and deterioration of hemodynamic parameters. The CT scan showed a left renal injury associated to an expansive retroperitoneal process. The abdominal exploration, vascular control of the renal pedicle and nephrectomy allowed a successful outcome.

The retroperitoneal tumors are infrequent and are classified according to the original tissue. This is a case presentation of a patient presenting with pain in right hypochondrium and a tumor in this zone, weight loss and painful discomfort in the anterolateral face of right thigh. In physical examination we found cutaneousmucous paleness and painless tumor in hypochondrium and right flank. Abdominal ultrasound (US) showed a homogenous mass of 14,11 cm and abdominal computed tomography allows to see a right retroperitoneal tumor rejecting the kidney. Excretory urogram showed a anteromedial rejection of right kidney. An encapsulated tumor with a few peritumoral adherences was removed. By histological study it was possible to confirm a fusiform cells tumor with hyperchromatism and nuclear pleomorphism, numerous mitosis and areas of necrosis and in the diagnosis of malign tumor of the sheath of a peripheral nerve.(author)

2010-01-01

The good prognosis of retroperitoneal and lateral pelvic lymphadenectomy has raised the question of whether total mesorectal excision is suitable for adequate staging of rectal adenocarcinoma patients. The aims of this study were to determine the accuracy of dye and probe detection of metastatic retroperitoneal and/or lateral pelvic nodes and to define the upstaging impact of retroperitoneal and lateral pelvic lymphadenectomy in rectal adenocarcinoma patients. Ninety-seven rectal adenocarcinoma patients were submitted to total mesorectal excision and retroperitoneal and lateral pelvic lymphadenectomy. Lymphoscintigraphy using technetium-99 m-phytate and patent blue was performed to detect blue and/or radioactive retroperitoneal and/or lateral pelvic nodes which were examined histopathologically and immunohistochemically with a step-sectioning technique. Mesorectal mean node count was 11.5 and retroperitoneal and/or lateral pelvic node was 11.7. Retroperitoneal and lateral pelvic lymphadenectomy identified metastases in 17.5%, upstaging 8.2%. Variables related to metastatic retroperitoneal and/or lateral pelvic nodes were the following: Stage III in total mesorectal excision specimens (P<0.04), pT3/pT4 tumors (P=0.047), high levels of carcinoembryonic antigen (P=0.014) and large tumors (P=0.03). Marker migration to retroperitoneal and/or lateral pelvic nodes occurred in 37.1%, upstaging 11.1%. The markers' accuracy in the detection of metastatic retroperitoneal and/or lateral pelvic nodes was 100%. Retroperitoneal and lateral pelvic lymphadenectomy detected an important rate of metastatic retroperitoneal and/or lateral pelvic nodes (RLPN), resulting in upstaging. When markers migrated, they were able to detect RLPN metastases. The use of markers should be improved in the identification of RLPN metastases for selective indication of retroperitoneal and lateral pelvic lymphadenectomy. (author)

We report two rare cases of iliopsoas bursitis extending into the retroperitoneal space. The first lesion contained much gas, mimicking a retroperitoneal abscess, and the second was responsible for atypical inguinal pain. The diagnosis was made by contrast-enhanced CT in both cases and arthrography in the first case. Iliopsoas bursitis in these two patients, it is hypothesized, extended into the retroperitoneum, at least in part, by way of intraneural or perineural structures. (orig.)

Although retroperitoneal sarcomas are rare tumours, they can be encountered by a wide variety of clinicians as they can be incidental findings on imaging or present with non specific symptoms and signs. Surgical resection can offer hope of cure and patient outcomes are improved when patients are managed in high-volume specialist centers. Failure to recognize retroperitoneal sarcomas on imaging can lead to inappropriate management in inexperienced centers. Therefore it is critical that a diagnosis of retroperitoneal sarcoma should be considered in the differential diagnosis of a retroperitoneal mass with prompt referral to a soft tissue sarcoma unit. In particular, the most common retroperitoneal sarcoma subtypes, liposarcoma and leiomyosarcoma, have characteristic imaging appearances which are discussed. This review therefore aims to set the context and guide clinicians through a diagnostic pathway for retroperitoneal masses in adults which arise extrinsic to the solid abdominal viscera.

Background: Previous studies of CT enhancement of lymphomatous lymph nodes (LLN) of the neck and the mediastinum showed that the LLN had lower enhancement values than normal lymph nodes. Purpose: To elucidate the contrast medium enhancement curves of LLN in the retroperitoneum by comparing the curves of LLN with those of normal lymph nodes, to test whether differences between these curves could be of diagnostic value, and to compare the present enhancement curves of LLN of the retroperitoneum with the curves of LLN of the neck and the mediastinum from previous similar investigations. Material and Methods: Twenty-eight consecutive patients with LLN of the retroperitoneum (three with Hodgkin's lymphoma [HL]) and 21 control patients with sarcomas and thus presumably normal retroperitoneal nodes underwent dynamic CT examinations. The previous, similar investigation of lymph nodes of the neck comprised 28 patients with LLN and the investigation of mediastinal lymph nodes comprised 24 patients with LLN. Results: The enhancement curves of the retroperitoneal LLN had significantly lower attenuation than those of the retroperitoneal control nodes. A combination of peak contrast value and time to peak adjusted to total body weight yielded a diagnostic accuracy which at the best showed a sensitivity of 90.5% with a specificity of 82.6%. The LLN of the retroperitoneum had higher attenuation values than corresponding nodes of the mediastinum but no significant difference was found between LLN of the retroperitoneum and LLN of the neck in previous similar investigations. Conclusion: The comparison of enhancement curves of retroperitoneal LLN with retroperitoneal control nodes showed a marked similarity with and substantiates our previous findings in lymph nodes of the neck and of the mediastinum. The best diagnostic accuracy was achieved by combining the parameters peak contrast value and time to peak and adjusting these values to the body weight. Peak enhancement of the

2015-06-01

Full Text Available Thymoma is an epithelial neoplasm of the thymus, which commonly lies in the anterior mediastinum and recurrences of thymoma generally are locally, and retroperitoneal recurrence is considered to be rare. A 46-year old Asian woman with invasive thymoma had undergone thymectomy 10 years ago. Computed tomography demonstrated a wellcircumscribed mass in the left retroperitoneal space. The patient had not any symptom including myasthenia gravis. Because on the anterior mediastinum area shows no sign of tumor recurrence and the mass adjacent to the vertebral body, neurogenic tumor was suspected. Surgical resection was performed using a retroperitoneal approach, which revealed the tumor adhering neighboring diaphragm. The tumor was histologically diagnosed to be type B1 thymoma according to the World Health Organization classification. The retroperitoneal mass was an unusual local recurrence after thymectomy. The patients whose had under invasive thymectomy should be evaluated carefully when finding retroperitoneal mass during follow-up.

Retroperitoneal fibrosis (RF) is an uncommon disease characterized by the presence of a chronic inflammatory reaction, with the formation of fibrous tissue that replaces the normal retroperitoneal tissue, trapping vessels and/or ureters. We present a retrospective review of 3 cases of idiopathic RF studied by means of ultrasound, CT scan and MR imaging, and we assess the features of the MR image, as well as its capacity for characterizing the lesion. We compare the findings obtained with 3 imaging techniques, describing the utility of each one, and their advantages and disadvantages in the assessment of this pathology. In MR, idiopathic RF appears as a hypodense mass in SET1, SE-T2 and STIR sequences. (Author) 9 ref

Retroperitoneal Gastrointestinal Type Schwannoma Presenting as a Renal Mass

Full Text Available Retroperitoneal schwannomas are extremely rare, and unreported in Urology. Often thought to be malignant from imaging the diagnosis is often delayed until Histology. We report a case of retroperitoneal schwanoma thought to be a malignant renal mass. Seventy three year old lady presented with abdominal pain. Imaging showed a mass attached to the renal pelvis thus she underwent a radical nephrectomy. Histology reported retroperitoneal schwannoma. Malignant forms are rare however treatment for these is surgical excision. Awareness of the existence of these tumors may help in avoiding unnecessary radical surgeries by opting for biopsy preoperatively.

Surgical anatomy of the retroperitoneal spaces, Part V: Surgical applications and complications.

Mirilas, Petros; Skandalakis, John E

2010-04-01

Knowledge of the surgical anatomy of the retroperitoneum is crucial for surgery of the retroperitoneal organs. Surgery is essential for treatment of retroperitoneal pathologies. The list of these diseases is extensive and comprises acute and chronic inflammatory processes (abscess, injury, hematoma, idiopathic fibrosis), metastatic neoplasms, and primary neoplasms from fibroadipose tissue, connective tissue, smooth and striated muscle, vascular tissue, somatic and sympathetic nervous tissue, extraadrenal chromaffin tissue, and lymphatic tissue. The retroperitoneum can be approached and explored by several routes, including the transperitoneal route and the extraperitoneal route. The retroperitoneal approach to the iliac fossa is used for ectopic renal transplantation. Safe and reliable primary retroperitoneal access can be performed for laparoscopic exploration. The anatomic complications of retroperitoneal surgery are the complications of the organs located in several compartments of the retroperitoneal space. Complications may arise from incisions to the somatic wall, somatic nerves, blood and lymphatic vessels, lymph nodes, visceral autonomous plexuses, and neighboring splanchna.

Hydronephrosis caused by retroperitoneal hematoma after a seatbelt injury is a unique clinical entity. A 21-year-old man, who had been wearing a seatbelt, was brought to our hospital after a motor vehicle collision, complaining of abdominal pain. Computed tomography (CT) revealed retroperitoneal hematoma in the upper pelvic region. Since he was hemodynamically stable throughout admission, he was managed conservatively. Seventeen days after initial discharge, the patient revisited our emergency department due to right back pain. CT scans indicated retroperitoneal hematoma growth resulting in hydronephrosis of the right kidney. Laparoscopic drainage of the retroperitoneal hematoma was successfully performed. His symptoms resolved after the surgery. Follow-up CT scans three months later demonstrated complete resolution of the hydronephrosis and retroperitoneal hematoma. Our case highlights a patient with delayed hydronephrosis because of retroperitoneal hematoma expansion after a seatbelt injury.

Full Text Available ABSTRACT A 69-year-old man presented at the hospital with complaints of prolonged stomach pain extending from the week prior. Enhanced computed tomography (CT revealed a low density area in the retroperitoneal space. A radiologist diagnosed the patient with retroperitoneal fibrosis. One week later, an enhanced CT revealed an exponential increase of the low density area and slight right hydronephrosis. Upon admission, prednisolone administration was initiated at a dose of 40mg/day. The size of the retroperitoneal soft tissue mass decreased gradually. Although the dose of prednisolone was tapered to 5mg, the patient is doing well without any sign of recurrence.

Objective: To determine CT and MRI imaging features in patients with a diagnosis of retroperitoneal lipo sarcoma. Material and Methods: Retrospective analysis of 6 cases, studied with CT and/or MRI in patients with retroperitoneal lipo sarcoma during the last 4 years at our institution. We analyzed symptoms, treatment and prognosis with special focus on the CT and MRI findings and their histological correlation. Results: the most frequent histological subtype in our group of patients was the pleomorphic lipo sarcoma (n=3). In the others cases, 2 were well differentiated and one was round-cell type. Retroperitoneal lipo sarcoma, especially the well differentiated, presented certain imaging patterns which allowed to suspect the subtype of tumor. Recurrences occurred in 50% (n=3). Mortality rate was 33.4% (n=2) (follow-up, 16 months). Conclusion: Both CT and MRI are methods which aid in the detection of this rare disorder, as well as in its diagnosis and follow-up. (author)

Abstract Rationale: Fascioliasis is a rare cause of liver abscesses, and its clinical course consists of hepatic phase and biliary phase. Patient concerns: We describe a 58-year-old female patient who presented with a 2-month history of intermittent fever and abdominal pain. An abdominal computed tomography (CT) revealed confluent low-density lesions in the liver. Complete surgical resection of these abscesses was performed, and postoperative pathological examination and serological tests confirmed a diagnosis of fascioliasis. However, 4 months after the surgery, follow-up CT revealed a lesion in the retroperitoneal area. Meanwhile, ultrasonography-guided percutaneous needle biopsy of the retroperitoneal lesion was performed, and a parasitic infection was suspected. Diagnoses: Retroperitoneal metastasis of hepatic phase fascioliasis. Interventions: The patient received parasitic resistance treatment with triclabendazole at a dose of 10 mg/kg/d for 2 consecutive days. Outcomes: After 2 courses of triclabendazole therapy, the retroperitoneal metastasis regressed to a minor lesion. Lessons: To the best of our knowledge, this is the first case report of retroperitoneal metastasis of fascioliasis, aimed at helping recognize the clinical features and treatment options of this rare disease.

To determine whether there is any difference in variceal distribution between patients with and without a history of esophageal variceal bleeding. To compare the distribution of varices, abdominal CT scans of 24 patients with a history of esophageal variceal bleeding (hemorrhagic group) and 90 patients without a history of bleeding (non-hemorrhagic group) were retrospectively assessed. The most common varices in both the hemorrhagic (n=21, 87.5%) and nonhemorrhagic group (n=53, 58.9%) were coronary varices, with a statistically significant frequency (p<.01). Esophageal varices were also more common in the hemorrhagic than the nonhemorrhagic group (n=19, 79.2% vs n=36, 40.0% : P<.005). Splenorenal shunts were more common in the nonhemorrhagic (n=8, 8.9%) than in the hemorrhagic group (n=0, 0%)(P<.05). Other types of varice such as paraumbilical (n=10, 41.7% vs n=21, 23.3%), perisplenic (n=6, 25% vs n=15, 16.7%) and retroperitoneal-paravertebral (n=11, 45.8% vs n=24, 26.7%) were more common in the hemorrhagic group, but without a statistically significant frequency. The frequency of coronary and esophageal varices was significant in patients with a history of esophageal variceal bleeding. In patients without such a history, splenorenal shunts were seen

Full Text Available Ventriculoperitoneal shunt is a routinely performed treatment in neurosurgical department. Intracerebral hemorrhage, as a complication after shunt catheterization, is really rare but with high mortality. In this study, we reported a case of a 74-year-old man who suffered from repeated intracerebral hemorrhage after ventriculoperitoneal shunt. The first hemorrhage happened 63 h after the 1st surgery, and most hematomas were located in the ipsilateral occipital lobe and intraventricles, along the ventricular catheter. Fresh blood clot casts blocked the external ventricular draining catheter, which was inserted into the right front horn during the 3rd surgery, indicating new intraventricular bleeding happened. A large hematoma in ipsilateral frontal lobe was detected on the 3rd day after the removal of external ventricular draining catheter. Different hemorrhagic locations and time points were encountered on the same case. We discussed the possible causes of repeated hemorrhage for this case, and the pre-operative preparation including risk evaluation in future clinical work.

Bleeding is the most frequent complication during ECMO support. Severe pre-existing bleeding has been considered a contraindication to ECMO application. Nevertheless, there are cases of successful ECMO application in patients with multiple trauma and hemorrhagic shock or head trauma and intracranial hemorrhage. ECMO has proved to be life-saving in several cases of life-threatening respiratory failure associated with pulmonary hemorrhage of various causes, including granulomatosis with polyangiitis (Wegener’s disease. We successfully applied ECMO in a 65-year-old woman with acute life-threatening respiratory failure due to diffuse massive pulmonary hemorrhage secondary to granulomatosis with polyangiitis, manifested as severe pulmonary-renal syndrome. ECMO sustained life and allowed disease control, together with plasmapheresis, cyclophosphamide, corticoids, and renal replacement therapy. The patient was successfully weaned from ECMO

Full Text Available Background : Early pathological classification of retroperitoneal masses is important for pin-point diagnosis and timely management. Aims : This study was done to evaluate the usefulness and drawbacks of guided fine needle aspiration cytology (FNAC of retroperitoneal masses covering a period of two years with an intention to distinguish between neoplastic and non-neoplastic lesions and to correlate with histologic findings. Materials and Methods : FNAC was done under radiological guidance in all cases using long needle fitted with disposable syringe. Appropriate staining was done and cytology was correlated with histology which was taken as the gold standard for comparison. Results : Fifty-one patients who presented with retroperitoneal masses were studied. Forty-four lesions were malignant cytologically and 7 were inflammatory (tuberculous. According to radiological and cytologic findings, we classified our cases into four groups: renal tumors, retroperitoneal lymphadenopathy, germ cell tumors, soft tissue tumors. Except for cases of non-Hodgkin lymphoma (NHL and metastatic lesions, we had sensitivity and specificity of 100%. In NHL the sensitivity and specificity were both 50%. In cases of metastatic adenocarcinoma, the sensitivity and specificity were 84.6% and 81.8%, respectively. Conclusions : Ignoring the pitfalls, guided FNAC is still an inexpensive and reliable method of early diagnosis of retroperitoneal lesions.

Massive retroperitoneal haemorrhage after extracorporeal shock wave lithotripsy (ESWL).

2011-01-01

A 76-year-old male suffering from nephrolithiasis developed a shock syndrome 5 days after extracorporal shock wave lithotripsy (ESWL). CT scan of the abdomen showed massive haemorrhage around the right kidney. Although nephrectomy was performed immediately, the haemorrhage could not be controlled. Numerous units of erythrocytes were transfused, but the patient died. The autopsy revealed massive retroperitoneal haemorrhage around the right kidney. The kidney showed a subcapsular haematoma and a rupture of the capsule. The right renal artery was dissected. The inferior vena cava was lacerated. Accordingly, a hemorrhagic shock as the cause of death was determined, which might mainly have resulted from the laceration of the inferior vena cava due to ESWL. ESWL seems to be a relatively non-invasive modality, but one of its severe complications is perirenal hematoma. The injuries of the blood vessels might have been caused by excessive shock waves. Subsequently, anticoagulation therapy had been resumed 3 days after EWSL, which might have triggered the haemorrhage. Physicians should note that a haemorrhage after an ESWL can occur and they should pay attention to the postoperative management in aged individuals especially when they are under anticoagulation therapy.

Detection of previous cerebral infarction on CT films of patients with no history of stroke is a common occurrence. The incidence of silent cerebral infarction was reported to be about 10 to 11 percent, but very few reports concerning asymptomatic cerebral hemorrhage available. However, recent clinical application of MRI has resulted in the detection of old asymptomatic hemorrhage in patients with no history known stroke-like episodes. The purpose of this study was to elucidate the incidence, the cause and the character of the asymptomatic cerebral hemorrhage among patients who had undergone MRI examinations. From September 1987 through June 1990, 2757 patients have undergone 3474 MR scans of the brain with 1.0 Tesla Siemens Magneton unit in our hospital. Seventeen patients showed no clinical signs or symptoms suggesting a stroke episode corresponding to the detected hemorrhagic lesion. The 17 patients corresponded to 0.6% of the patients who underwent MRI, 1.5% of the patients with cerebrovascular disease and 9.5% of the patients with intracerebral hemorrhage(ICH), which was rather higher than expected. Among the 17 patients, 12 were diagnosed as primary ICH and 5 as secondary ICH. Most of the primary asymptomatic hemorrhage were hypertensive ones and slit-like curvilinear lesions between the putamen and claustrum or external capsule. The secondary asymptomatic hemorrhage were due to AVM and angiomas in the frontal cortex, thalamus and pons. (author)

Full Text Available Spontaneous cerebral hemorrhage or intracranial hemorrhage accounts for 10-15% of all strokes. Intracranial hemorrhage is much less common than ischemic stroke, but has higher mortality and morbidity, one of the leading causes of severe disability. Various alterations, among these the endocrine were identified when an intracerebral hemorrhage, these stress-mediated mechanisms exacerbate secondary injury. Deep knowledge of the injuries which are directly involved alterations of glucose, offers insight as cytotoxicity, neuronal death and metabolic dysregulations alter the prognosis of patients with spontaneous intracerebral hemorrhage.

Retroperitoneal seminoma is a very rare form of cancer, with embryological origin represented by primordial germ cells from the urogenital ridges left behind during the fetal development. Extragenital germ cell tumors can also occur in the mediastinum or the pineal gland. The aim of this paper is to outline the particularities and draw embryological, histopatological and treatment conclusions regarding extragonadal germ cell tumors. A 43-year-old patient without any additional pathology was admitted for anemia of unknown etiology. The clinical examination revealed through deep abdominal palpation a mass in the left flank, and normal testes. Thoraco-abdomino-pelvic computed tomography (CT) scan showed a large retroperitoneal tumor adjacent to the great vessels in the left lumbo-iliac region. The blood work revealed just a low hemoglobin and hematocrit. With the established diagnosis of retroperitoneal tumor, radical surgical removal was decided. During the surgery, we were required to dissect a large solid encapsulated tumor mass from the aorta and the common iliac artery, starting at the renal pedicle all the way to the left iliac bifurcation. The surgical access was obtained through a transperitoneal left subcostal incision prolonged pararectally. Histopathological and immunohistochemical studies revealed a seminoma of the usual type. After the histological findings, the patient's tumor markers were investigated (LDH - lactate dehydrogenase, βHCG - beta-human chorionic gonadotropin, αFP - alpha-fetoprotein), all values being within normal ranges. In addition, the left testicle was thoroughly reexamined, clinically, through ultrasound and magnetic resonance imaging (MRI) scans, and no abnormalities were observed. After the surgery, the patient followed three courses of chemotherapy (BEP - Bleomycin, Etoposide and Cisplatin). The CT scan done 24 months after surgery found no signs of local or distant tumor recurrence. The patient entered a follow-up schedule

Percutaneous CT-guided radiofrequency ablation (RFA) is becoming more and more established in the treatment of various neoplasms, including retroperitoneal tumors of the kidneys and the adrenal glands. We report the case of RFA in a patient suffering from the third relapse of a retroperitoneal liposarcoma in the left psoas muscle. After repeated surgical resection and supportive radiation therapy of a primary retroperitoneal liposarcoma and two surgically treated recurrences, including replacement of the ureter by a fraction of the ileum, there was no option for further surgery. Thus, we considered RFA as the most suitable treatment option. Monopolar RFA was performed in a single session with a 2-cm umbrella-shaped LeVeen probe. During a 27-month follow-up period the patient remained free of tumor.

Full Text Available Although cases of lymphoplasmacytic sclerosing pancreatitis (LSP associated with idiopathic retroperitoneal fibrosis have been reported, the association is rare. We describe a 74-year-old man who presented with obstructive jaundice and weight loss. Nineteen months earlier, he had been diagnosed with idiopathic retroperitoneal fibrosis and treated with bilateral ureteric stents. Initial investigations were suggestive of a diagnosis of LSP, however, a malignant cause could not be ruled out. He underwent an exploratory laparotomy and frozen sections confirmed the diagnosis of LSP. An internal biliary bypass was performed using a Roux loop of jejunum, and the patient made an uneventful recovery. This case illustrates the difficulty in distinguishing LSP from pancreatic carcinoma preoperatively.

Colonic perforation is a lethal condition presenting high morbidity and mortality in spite of urgent surgical treatment. This study investigated the surgical outcome of patients with colonic perforation associated with retroperitoneal contamination. Retrospective analysis was performed for 30 patients diagnosed with colonic perforation caused by either inflammation or ischemia who underwent urgent surgical treatment in our facility from January 2005 to December 2014. Patient characteristics were analyzed to find risk factors correlated with increased postoperative mortality. Using the Physiological and Operative Severity Score for the Enumeration of Mortality and Morbidity (POSSUM) audit system, the mortality and morbidity rates were estimated to verify the surgical outcomes. Patients with retroperitoneal contamination, defined by the presence of retroperitoneal air in the preoperative abdominopelvic CT, were compared to those without retroperitoneal contamination. Eight out of 30 patients (26.7%) with colonic perforation had died after urgent surgical treatment. Factors associated with mortality included age, American Society of Anesthesiologists (ASA) physical status classification, and the ischemic cause of colonic perforation. Three out of 6 patients (50%) who presented retroperitoneal contamination were deceased. Although the patients with retroperitoneal contamination did not show significant increase in the mortality rate, they showed significantly higher ASA physical status classification than those without retroperitoneal contamination. The mortality rate predicted from Portsmouth POSSUM was higher in the patients with retroperitoneal contamination. Patients presenting colonic perforation along with retroperitoneal contamination demonstrated severe comorbidity. However, retroperitoneal contamination was not found to be correlated with the mortality rate.

2003-01-01

Purpose: To evaluate the different imaging findings (US, CT and MRI) in retroperitoneal schwannoma. Materials and methods: 5 patients (3 male and 2 females) with a diagnosis of retroperitoneal schwannoma were retrospectively evaluated. Ages ranged from 33 to 63 years (means 54 years). The images (US, CT and MR) were analyzed and correlated to histopathologic results. Results: The most frequent clinical finding was abdominal pain (60%). A presumptive diagnosis prior to surgery was suggested in 3/5 cases that had well-defined masses with a predominant cystic appearance. All patients underwent surgery with tumoral resection. Only 2 patients (40%) had recurrence within a three years period of follow-up. Conclusion: Retroperitoneal schwannoma is an infrequent tumor. In our series, no pathognomotic features were observed on US, CT or MRI. However, 3/5 tumors showed high signal intensity on T2-weighted images due to cystic areas. (author)

A 34-year-old woman presented with a left-sided suprarenal space-occupying lesion on sonography. Culture of material obtained during sonographic-guided puncture of the retroperitoneal lesion yielded a mixed flora of Actinomyces and Peptostreptococcus. Initially, a misleading diagnosis of an adrenal pheochromocytoma was initiated by highly positive metaiodobenzylguanidine scintigraphy after chemical chemistry vanillylmandelic acid (VMA) test showed elevated values for adrenaline and its derivatives. Retroperitoneal actinomycosis with yet unproven spread into thoracic and cervical compartments is a particular unusual presentation of an infection with these organisms. Because it may mimic subacute infections or malignant masses in terms of clinical and laboratory findings, radiological diagnosis of this entity may be difficult. The diagnosis was based on results of culture and the response of the patient to long-term penicillin-derivate therapy after surgical drainage of the suprarenal abscess formation. (orig.)

Secondary pulmonary hemorrhage increases the risk of mortality in patients with antineutrophil cytoplasmic antibody-associated vasculitis (AAV); plasma exchange therapy may improve outcomes in these patients. We conducted a retrospective cohort study to investigate the effect of plasma exchange therapy on short-term prognoses in patients with pulmonary hemorrhage secondary to AAV. This study utilized the Diagnosis Procedure Combination database, which is a nationwide inpatient database in Japan. We checked the abstract data and medical actions and identified the patients with pulmonary hemorrhage secondary to AAV who required proactive treatment between 2009 and 2014. To compare the in-hospital mortality, we performed propensity score matching between the plasma exchange and non-plasma exchange groups at a ratio of 1:1. Of the 52,932 patients with AAV, 940 developed pulmonary hemorrhage as a complication. A total of 249 patients from 194 hospitals were eligible for the study. Propensity score matching at a ratio of 1:1 was performed, and 59 pairs were formed (plasma exchange group, n = 59; non-plasma exchange group, n = 59). A statistically significant difference was found in the all-cause in-hospital mortality between the plasma exchange and non-plasma exchange groups (35.6% vs. 54.2%; p = 0041; risk difference, -18.6; 95% confidence interval (CI), -35.4% to -0.67%). Thus, plasma exchange therapy was associated with improved in-hospital mortality in patients with pulmonary hemorrhage secondary to AAV.

Full Text Available Excision of a suspected retroperitoneal, duodenal duplication cyst was performed in a pre-operatively normotensive patient under combined epidural and general anaesthesia. Intraoperatively, the cystic tumour was discovered to be a retroperitoneal mass, free from duodenal or adrenal origin. Development of severe arrhythmias, ST segment changes and hypertensive spikes during cyst handling and dissection suggested the possibility of a catecholamine-secreting tumour. These were managed effectively with pharmacological agents. Subsequently, histopathology of the specimen revealed a paraganglioma. Vasoactive tumour has to be suspected in every patient undergoing anaesthesia for retroperitoneal cystic lesion.

2008-01-01

Traumatic injury of the abdominal aorta is rare and potentially lethal (Yeh et al., J Vasc Surg 42(5):1007-1009, 2005; Chicos et al., Chirurgia (Bucur) 102(2):237-240, 2007) as it can result in major retroperitoneal hemorrhage, requiring an urgent open surgery. In case of concomitant bowel injury or other conditions of hostile abdomen, endovascular repair can be an alternative treatment. This case report deals with a 50-year-old man presenting at the emergency ward with three stab wounds: two in the abdomen and one in the chest. During explorative laparotomy, liver laceration and bowel perforation were repaired. One day later, abdominal CT-scan revealed an additional retroperitoneal hematoma associated with an aortic pseudoaneurysm, located anteriorly 3 cm above the aortic bifurcation. Because of the risk of graft infection, an endovascular repair of the aortic injury using a Gore excluder stent-graft was performed. Radiological and clinical follow-up revealed a gradual shrinkage of the pseudo-aneurysm and no sign of graft infection at two years' follow-up.

Background Iron deficiency anemia remains a major global health problem. Higher iron demands provide the potential for a targeted preventative approach before anemia develops. The primary study objective was to develop and validate a metric that stratifies recommended dietary iron intake to compensate for patient-specific non-menstrual hemorrhagic losses. The secondary objective was to examine whether iron deficiency can be attributed to under-replacement of epistaxis (nosebleed) hemorrhagic iron losses in hereditary hemorrhagic telangiectasia (HHT). Methodology/Principal Findings The hemorrhage adjusted iron requirement (HAIR) sums the recommended dietary allowance, and iron required to replace additional quantified hemorrhagic losses, based on the pre-menopausal increment to compensate for menstrual losses (formula provided). In a study population of 50 HHT patients completing concurrent dietary and nosebleed questionnaires, 43/50 (86%) met their recommended dietary allowance, but only 10/50 (20%) met their HAIR. Higher HAIR was a powerful predictor of lower hemoglobin (p = 0.009), lower mean corpuscular hemoglobin content (pstopped. Conclusions/significance HAIR values, providing an indication of individuals’ iron requirements, may be a useful tool in prevention, assessment and management of iron deficiency. Iron deficiency in HHT can be explained by under-replacement of nosebleed hemorrhagic iron losses. PMID:24146883

Full Text Available Introduction. Retroperitoneal sarcomas are uncommon large malignant tumors. Methods. Forty-one consecutive patients with localized retroperitoneal sarcoma were retrospectively studied. Results. Median age was 58 years (range 20–91 years. Median tumor size was 17.5 cm (range 4–41 cm. Only 2 tumors were <5 cm. Most were liposarcoma (44% and high-grade (59%. 59% were stage 3 and the rest was stage 1. Median followup was 10 months (range 1–106 months. Thirty-eight patients had an initial complete resection; 15 (37% developed recurrent sarcoma and 12 (80% had a second complete resection. Patients with an initial complete resection had a 5-year survival of 46%. For all patients, tumor grade affected overall survival (=.006. Complete surgical resection improved overall survival for high-grade tumors (=.03. Conclusions. Tumor grade/stage and complete surgical resection for high-grade tumors are important prognostic variables. Radiation therapy or chemotherapy had no significant impact on overall or recurrence-free survival. Complete surgical resection is the treatment of choice for patients with initial and locally recurrent retroperitoneal sarcoma.

Full Text Available Enteric duplication cysts lacking anatomic association with the gastrointestinal tract are called isolated enteric duplication cysts (IEDCs. We present an atypical case of a retroperitoneal IEDC with a tortuous tubular complex shape that enfolded the surrounding retroperitoneal fat and mimicked a retroperitoneal teratoma. Multiplanar reconstruction images should be used to evaluate such a lesion correctly. A tortuous tubular complex shape could be a key finding to differentiate from other retroperitoneal cysts.

To describe a step-by-step guide for successful implementation of the retroperitoneal approach to robotic partial nephrectomy (RPN) PATIENTS AND METHODS: The patient is placed in the flank position and the table fully flexed to increase the space between the 12th rib and iliac crest. Access to the retroperitoneal space is obtained using a balloon-dilating device. Ports include a 12-mm camera port, two 8-mm robotic ports and a 12-mm assistant port placed in the anterior axillary line cephalad to the anterior superior iliac spine, and 7-8 cm caudal to the ipsilateral robotic port. Positioning and port placement strategies for successful technique include: (i) Docking robot directly over the patient's head parallel to the spine; (ii) incision for camera port ≈1.9 cm (1 fingerbreadth) above the iliac crest, lateral to the triangle of Petit; (iii) Seldinger technique insertion of kidney-shaped balloon dilator into retroperitoneal space; (iv) Maximising distance between all ports; (v) Ensuring camera arm is placed in the outer part of the 'sweet spot'. The retroperitoneal approach to RPN permits direct access to the renal hilum, no need for bowel mobilisation and excellent visualisation of posteriorly located tumours. © 2014 The Authors.

Ishikawa, Kazuo; Nakao, Shota; Nakamuro, Makoto; Huang, Tai-Ping; Nakano, Hiroshi

2016-07-01

Recently, the concept of interfascial planes has become the prevalent theory among radiologists for understanding the retroperitoneal anatomy, having replaced the classic tricompartmental theory. However, it is a little known fact that the concept remains incomplete and includes embryological errors, which have been revised on the basis of our microscopic study. We believe that the concept not only provides a much clearer understanding of the retroperitoneal anatomy, but it also allows further development for diagnosis and treatment of retroperitoneal injuries and diseases, should it become an accomplished theory. We explain the history and outline of the concept of interfascial planes, correct common misunderstandings about the concept, explain the unconsciously applied therapeutic procedures based on the concept, and present future perspectives of the concept using our published and unpublished data. This knowledge could be essential to acute care physicians and surgeons sometime soon.

Retroperitoneal foregut duplication cyst is an extremely rare congenital malformation. Pathologically, this lesion contains both gastric mucosa and respiratory type mucosa; radiologically, it is often challenging to differentiate it from the other cystic neoplasms that present a similar appearance. We report on a case of retroperitoneal foregut duplication cyst that was lined by both gastric and pseudostratified ciliated columnar epithelium, and it was also accompanied by a pancreatic pseudocyst. Initially, it presented with peripancreatic and intrapancreatic cystic masses in an asymptomatic 30-year-old man, and this man has since undergone surgical resection

Retroperitoneal Paraganglioma – a rare cause of arterial hypertension

Directory of Open Access Journals (Sweden)

Isabel Silva

2017-03-01

Full Text Available Paragangliomas are rare neuroendocrine tumours, most commonly found in adults. These differ from pheochromocytomas in that their location is extra-adrenal, and they are responsible for about 1% of arterial hypertension aetiologies. We report the case of a 30-year-old female whose past medical history was unremarkable. However, her arterial hypertension led to further examination in search of secondary aetiologies, in which a retroperitoneal mass and an increase in levels of catecholamines were detected; findings that led to the final diagnosis of paraganglioma. A multidisciplinary team, whose approach was to use pharmacological alpha-adrenergic blocking agents and a surgical resection of the lesion, treated the patient. The patient is clinically well but will continue to be monitored as an outpatient, and genetic testing is being encouraged.

Full Text Available The triton tumor was described in 1932 by Masson, as a peripheral nerve sheath malignancy with rabdomioblástica differentiation. The retroperitoneal location is extremely rare, only nine cases have been reported in children. The clinical picture depends on the size of the tumor and the organs involved, their retroperitoneal location is usually asymptomatic. The mainstay of treatment is the surgical excision of the tumor. We report the case of a child with retroperitoneal location of the tumor. A complete resection of it was performed. The patient had an uneventful postoperative course. He is currently under control. There is no evidence of relapse.

2009-01-01

Full Text Available A huge left renal capsular leiomyoma mimicking retroperitoneal sarcoma presented in a patient as an abdominal mass. Computed tomography displayed a large heterogeneous retro-peritoneal mass in the left side of the abdomen with inferior and medial displacement as well as loss of fat plane with the left kidney. Surgical exploration revealed a capsulated mass that was tightly adherent to the left kidney; therefore, total tumor resection with radical left nephrectomy was performed. Histopathology ultimately confirmed the benign nature of the mass. This is the largest leiomyoma reported in literature to the best of our knowledge.

The surgical finding was three enlarged nodes, positive for metastatic disease. Patient was referred to adjuvant chemotherapy. This case suggests that the Intergroup Rhabdomyosarcoma Study Group IV protocol is subject to questions regarding adolescents with paratesticular rhabdomyosarcoma, and that negative retroperitoneal CT does not preclude the need of lymph node dissection.

2011-01-01

Delayed detection of an internal hemorrhage may result in serious disabilities and possibly death for a patient. Currently, there are no portable medical imaging instruments that are suitable for long-term monitoring of patients at risk of internal hemorrhage. Electrical impedance tomography (EIT) has the potential to monitor patients continuously as a novel functional image modality and instantly detect the occurrence of an internal hemorrhage. However, the low spatial resolution and high sensitivity to noise of this technique have limited its application in clinics. In addition, due to the circular boundary display mode used in current EIT images, it is difficult for clinicians to identify precisely which organ is bleeding using this technique. The aim of this study was to propose an optimized strategy for EIT reconstruction to promote the use of EIT for clinical studies, which mainly includes the use of anatomically accurate boundary shapes, rapid selection of optimal regularization parameters and image fusion of EIT and computed tomography images. The method was evaluated on retroperitoneal and intraperitoneal bleeding piglet data. Both traditional backprojection images and optimized images among different boundary shapes were reconstructed and compared. The experimental results demonstrated that EIT images with precise anatomical information can be reconstructed in which the image resolution and resistance to noise can be improved effectively

Renal fascial network in retroperitoneal extension of pathologic processes

International Nuclear Information System (INIS)

Raptopoulos, V.; Kleinman, P.K.; Marks, S.C. Jr.; Davidoff, A.

1987-01-01

The concept of the fascial network emerged after careful analysis of CT scans of 100 patients with a variety of retroperitoneal abnormalities, and after correlation of CT scans and anatomic dissections performed on eight unembalmed cadavers in which different-colored barium-mixed liquid latex was injected in various retroperitoneal compartments. Fat lobules are supported and connected with each other by surrounding thin layers of connective tissue. Thicker connective tissue lamellae (septa) connect and support organs and fascia. Thus, a fascial network infrastructure exists in which fat lobules act as mechanical barriers to the spread of pathologic processes, while these processes tend to take the course of least resistance by spreading along or dissecting within fascial and septal planes. The fascial network acts as a roadway, conduit, and barrier to spread in the retroperitoneum and fatty tissue in general. The insights afforded by the fascial network concept unwind the traditional views regarding the dynamics of retroperitoneal pathology

Full Text Available Ibrutinib (Imbruvica; Pharmacyclics is the first Food and Drug Administration–approved inhibitor of Burton’s tyrosine kinase (BTK. Attenuation of BTK signaling ultimately leads to inhibition of B-cell proliferation and apoptosis. After a series of clinical trials, the Food and Drug Administration approved ibrutinib in patients with relapsed chronic lymphocytic leukemia in 2014 and Waldenström’s macroglobulinemia in 2015. Those trials included rare grade 3+ hemorrhagic events associated with ibrutinib. Herein, we report a unique presentation of back pain due to iliopsoas muscle hemorrhage in a patient with Waldenström’s macroglobulinemia after initiation of ibrutinib.

Embryologically, the retroperitoneal (extraperitoneal) connective tissue includes three strata, which respectively form the internal fascia lining of the body wall, the renal fascia, and the covering of the gastrointestinal viscera. All organs, vessels, and nerves, that lie on the posterior abdominal wall, along with their tissues and surrounding connective and fascial planes, are collectively referred to as the retroperitoneum. The retroperitoneal space is the area of the posterior abdominal wall that is located between the parietal peritoneum and the fascia. Within the greater retroperitoneal space, there are also several small spaces, or subcompartments. Loose connective tissue and fat surround the anatomic entities, and, to a variable degree, occupy the subcompartments. The multilaminar thoracolumbar (lumbodorsal) fascia begins at the occipital area and terminates at the sacrum.

We studied the clinical features and CT findings of 20 cases with fulminant subarachonid hemorrhages in the acute stage. They were admitted to our hospital within 3 hours after the attack as DOA (dead on arrival) or near DOA. CT-visualized subarachnoid hemorrhages were located in the basal cisterns surrounding the brain stem in all cases. In 90 % of the cases, the subarachnoid hemorrhage formed a clot or a thick layer. Massive intracerebral hematomas were observed in 10 % of the cases. Acute intraventricular hemorrhages were seen in 80 % of the cases. The mechanism of intraventricular hemorrhage in 70 % of the cases was of the reflux type, which was characterized by a reflux of the severe subarachnoid hemorrhage in the basal cistern. Acute and diffuse brain swelling on CT scan was observed in several cases, which also showed initial increased intracranial pressures. The major mechanisms leading to acute death or a very severe state soon after subarachnoid hemorrhage might be caused by acute brain-stem failure due to severe subarachnoid hemorrhages in the basal cisterns surrounding the brain-stem and an acute increase in intracranial pressure by cerebral edema following subarachnoid hemorrhage and secondary cerebral ischemia due to cardiac and respiratory arrest.

Increasing rates of opioid abuse, particularly fentanyl, may lead to more presentations of unusual effects of opioid toxicity. Diffuse alveolar hemorrhage is a rare complication of fentanyl overdose. A 45-year-old male presented in hypoxic respiratory failure secondary to diffuse alveolar hemorrhage requiring intubation. Comprehensive drug screening detected fentanyl without exposure to cocaine. Further history upon the patient's recovery revealed exposure to snorted fentanyl powder immediately prior to presentation. Diffuse alveolar hemorrhage is a potential, though rare, presentation of opioid intoxication. Recognition of less common complications of opioid abuse such as diffuse alveolar hemorrhage is important in proper management of overdoses.

Laparoscopy in penetrating abdominal injuries is now accepted and practiced in many modern trauma centres. However its role in evaluating and managing retroperitoneal injuries is not yet well established. The aim of this study was to document our experience in using laparoscopy in a setting of penetrating abdominal injuries with suspected retroperitoneal injury in haemodynamically stable patients. A retrospective descriptive study of prospectively collected data from a trauma unit at Dr George Mukhari Academic Hospital (DGMAH) was done. All haemodynamically stable patients with penetrating abdominal injury who were offered laparoscopy from January 2012 to December 2015 were reviewed and those who met the inclusion criteria were analysed. A total of 284 patients with penetrating abdominal injuries were reviewed and 56 met the inclusion criteria and were analysed. The median age was 30.8 years (15-60 years) and males constituted 87.5% of the study population. The most common mechanism of injury was penetrating stab wounds (62.5%). Forty-five patients (80.3%) were managed laparoscopically, of these n=16 (28.5%) had retroperitoneal injuries that required surgical intervention. The most commonly injured organ was the colon (19.6%). The conversion rate was 19.6% with most common indication for conversion been active bleeding (14%). The complication rate was 7.14% (N=4) and were all Clavien-Dindo grade 3. There were no recorded missed injuries and no mortality. The positive outcomes documented in this study with no missed injuries and absence of mortality suggests that laparoscopy is a feasible option in managing stable patients with suspected retroperitoneal injuries.

Traumatic rupture of adrenal pseudocyst leading to massive hemorrhage in retroperitoneum

Full Text Available We present the case of a patient who had a large pseudocyst in the right adrenal gland, which was ruptured following blunt abdominal trauma, leading to a voluminous hemorrhage in retroperitoneum. A 29-year old female patient was admitted in the emergency room following a fall from stairs with trauma in right flank. She underwent a computerized tomography that evidenced a large retroperitoneal collection, with no apparent renal damage. She was submitted to surgery, where a large ruptured cyst was observed, originating from the upper portion of the right adrenal gland. Cystic diseases of adrenal gland are rare. Highly voluminous cysts can be damaged in cases of blunt trauma to the lumbar region leading to large hematomas in retroperitoneum.

Since its initial description by Mercan et al. laparoscopic posterior retroperitoneal (PR) adrenalectomy has served as an alternaltive to the transabdominal (TL) approach for the treatment of adrenal pathologies. Robotic adrenal surgery has been reported to improve surgeon ergonomics and facilitate dissection. In patients with bilateral adrenal masses, PR adrenalectomy may be the approach of choice. We herein describe the technique, discuss its limitations and present a critical review of the current literature. © 2015 Wiley Periodicals, Inc.

Vascular type Ehlers-Danlos Syndrome with fatal spontaneous rupture of a right common iliac artery dissection: case report and review of literature

2014-01-01

Vascular Ehlers-Danlos Syndrome (previously Ehlers-Danlos IV) is a rare autosomal dominant collagen vascular disorder caused by a 2q31 COL3A1 gene mutation encoding pro-alpha1 chain of type III collagen (in contrast to classic Ehlers-Danlos, caused by a COL5A1 mutation). The vascular type accounts for less than 4% of all Ehlers-Danlos cases and usually has a poor prognosis due to life threatening vascular ruptures and difficult, frequently unsuccessful surgical and vascular interventions. In 70% of cases, vascular rupture or dissection, gastrointestinal perforation, or organ rupture is a presenting sign. We present a case of genetically proven vascular Ehlers-Danlos with fatal recurrent retroperitoneal hemorrhages secondary to a ruptured right common iliac artery dissection in a 30-year-old male. This case highlights the need to suspect collagen vascular disorders when a young adult presents with unexplained retroperitoneal hemorrhage, even without family history of such diseases.

Minocha, Priyanka; Setia, Ankur

2016-11-01

Abdominal pain is a very common symptom in all age groups but retroperitoneal fibrosis is a rare differential diagnosis suspected in young patients presenting with nonspecific abdominal pain and symptoms of obstructive uropathy. Presented here is a case of a 16-year-old boy who presented with symptoms of persistent abdominal pain and a previous history of swelling in the left leg. A computed tomography (CT) scan suggested retroperitoneal fibrosis and an exploratory laparotomy and histopathological examination were performed for definitive diagnosis. This case report is intended to promote awareness of retroperitoneal fibrosis in young patients among health care providers.

Two Case Reports and Actual Treatment Approachs of Retroperitoneal Fibrosis

Directory of Open Access Journals (Sweden)

2013-06-01

Full Text Available Retroperitoneal fibrosis (RPF is a rare disease of unclear etiology, which is characterized by a chronic non specific inflammation of the retroperitoneum. This inflammation of the retroperitoneum may entrap and obstruct retroperitoneal structures, particularly the ureters. Patients with RPF show non specific clinical symptoms, including poorly localized back pain, general malaise, weight loss, anemia, features of renal failure and occasionally, mild fever. The early symptoms are non specific and an accurate diagnosis is often achieved only subsequent to urological obstruction or the occurrence of renal failure. Although a number of scientific journals devoted to RPF are present in the litera¬ture, there is no accepted diagnostic or therapeutic strategy for this disease. However, there are several therapeutic strate¬gies which have been proven to be effective. Hereby, we reported two cases of retroperitoneal fibrosis which had similar symptoms and findings but different responses to medical treatment .We aimed to discuss challanges of RPF%u2019s diagnosis and the treatment protocol.

2009-01-01

Purpose: To evaluate the applicability of carbon ion radiotherapy (CIRT) for unresectable retroperitoneal sarcomas with regard to normal tissue morbidity and local tumor control. Methods and Materials: From May 1997 to February 2006, 24 patients (17 male and 7 female) with unresectable retroperitoneal sarcoma received CIRT. Age ranged from 16 to 77 years (median, 48.6 years). Of the patients, 16 had primary disease and 8 recurrent disease. Histologic diagnoses were as follows: malignant fibrous histiocytoma in 6, liposarcoma in 3, malignant peripheral nerve sheath tumor in 3, Ewing/primitive neuroectodermal tumor (PNET) in 2, and miscellaneous in 10 patients. The histologic grades were as follows: Grade 3 in 15, Grade 2-3 in 2, Grade 2 in 3, and unknown in 4. Clinical target volumes ranged between 57 cm 3 and 1,194 cm 3 (median 525 cm 3 ). The delivered carbon ion dose ranged from 52.8 to 73.6 GyE in 16 fixed fractions over 4 weeks. Results: The median follow-up was 36 months (range, 6-143 months). The overall survival rates at 2 and 5 years were 75% and 50%, respectively. The local control rates at 2 and 5 years were 77% and 69%. No complications of the gastrointestinal tract were encountered. No other toxicity greater than Grade 2 was observed. Conclusions: Use of CIRT is suggested to be effective and safe for retroperitoneal sarcomas. The results obtained with CIRT were a good overall survival rate and local control, notwithstanding the fact that most patients were not eligible for surgical resection and had high-grade sarcomas.

Filmar, Gilad A; Lotze, Peter M; Fisher, Hilaire W

2012-01-01

To describe a rare case of a retroperitoneal duplication cyst that fistulized to the vagina. Case description and discussion of a patient found to have an intestinal duplication cyst. A patient presented for a laparoscopic hysterectomy because of menorrhagia and a fibroid uterus. She also complained of recurrent urinary tract infections (UTIs) and a vaginal discharge. A retroperitoneal intestinal duplication cyst that fistulized to the vagina and caused her recurrent UTIs was identified. Surgical resection of the cyst resolved her complaint of recurrent UTIs. Retroperitoneal intestinal duplication cysts are rare congenital anomalies with vague clinical manifestations. The finding of a fistulous communication to the vagina originating from such a structure can be associated with recurrent UTIs.

Soft tissue sarcomas are a group of heterogeneous neoplasms with more than 50 histological subtypes exhibiting major differences in terms of pathogenesis, genetic alterations and clinical behavior. Sarcomas represent approximately 1% of malignancies with retroperitoneal sarcomas representing 10-15% of all soft tissue sarcomas. Surgery is currently the only modality which offers the chance of cure. Surgery for retroperitoneal sarcomas presents specific challenges due their location in a complex space surrounded by vital structures and visceral organs often prohibiting resection with wide margins. Furthermore, even after complete resection local recurrence is common and the leading cause of death. In this article the authors describe the initial investigations, prognostic factors and optimal surgical management. The evidence and current research as regards the role of multimodality treatment is reviewed and discussed.

Hemorrhage-adjusted iron requirements, hematinics and hepcidin define hereditary hemorrhagic telangiectasia as a model of hemorrhagic iron deficiency.

Full Text Available Iron deficiency anemia remains a major global health problem. Higher iron demands provide the potential for a targeted preventative approach before anemia develops. The primary study objective was to develop and validate a metric that stratifies recommended dietary iron intake to compensate for patient-specific non-menstrual hemorrhagic losses. The secondary objective was to examine whether iron deficiency can be attributed to under-replacement of epistaxis (nosebleed hemorrhagic iron losses in hereditary hemorrhagic telangiectasia (HHT.The hemorrhage adjusted iron requirement (HAIR sums the recommended dietary allowance, and iron required to replace additional quantified hemorrhagic losses, based on the pre-menopausal increment to compensate for menstrual losses (formula provided. In a study population of 50 HHT patients completing concurrent dietary and nosebleed questionnaires, 43/50 (86% met their recommended dietary allowance, but only 10/50 (20% met their HAIR. Higher HAIR was a powerful predictor of lower hemoglobin (p = 0.009, lower mean corpuscular hemoglobin content (p<0.001, lower log-transformed serum iron (p = 0.009, and higher log-transformed red cell distribution width (p<0.001.

Pawar, Nilesh H; O'Riordan, Jennifer A; Malik, Preeti; Vasanwala, Farhad F

2017-09-27

Stroke is one of the most common causes of mortality and morbidity worldwide. Hemorrhagic stroke comprises 10-20% of strokes. Here, we present a case report of hemorrhagic stroke that may have been secondary to untreated Obstructive Sleep Apnea (OSA) in a young man with no other cardiovascular risk factors or features of metabolic syndrome. A 32-year-old man was admitted for hemorrhagic stroke. An initial thorough workup for the etiology of stroke was inconclusive. Eventually, a polysomnography was done, which demonstrated OSA suggesting that untreated OSA may have contributed to his stroke. OSA may cause hemorrhagic stroke by nocturnal blood pressure surge. So, all physicians should consider doing polysomnography for unexplained hemorrhagic stroke or in patients at risk. Diagnosing and treating OSA would be critical in preventing hemorrhagic stroke and its recurrences.

Clinical evidence reveals the existence of a trauma-induced secondary cardiac injury (TISCI) that is associated with poor patient outcomes. The mechanisms leading to TISCI in injured patients are uncertain. Conversely, animal models of trauma hemorrhage have repeatedly demonstrated significant cardiac dysfunction following injury, and highlighted mechanisms through which this might occur. The aim of this review was to provide an overview of the animal studies describing TISCI and its pathophysiology.Basic science models of trauma show evidence of innate immune system activation via Toll-like receptors, the exact protagonists of which remain unclear. Shortly following trauma and hemorrhage, cardiomyocytes upregulate gene regulatory protein and inflammatory molecule expression including nuclear factor kappa beta, tumor necrosis factor alpha, and interleukin-6. This is associated with expression of membrane bound adhesion molecules and chemokines leading to marked myocardial leukocyte infiltration. This cell activation and infiltration is linked to a rise in enzymes that cause oxidative and nitrative stress and subsequent protein misfolding within cardiomyocytes. Such protein damage may lead to reduced contractility and myocyte apoptosis. Other molecules have been identified as cardioprotective following injury. These include p38 mitogen-activated protein kinases and heat shock proteins.The balance between increasing damaging mediators and a reduction in cardio-protective molecules appears to define myocardial function following trauma. Exogenous therapeutics have been trialled in rodents with promising abilities to favorably alter this balance, and subsequently lead to improved cardiac function.

Laparoscopy is increasingly utilised in the trauma setting. However, its safety and reliability in evaluating and managing retroperitoneal injuries are not known. The aim of this study was to analyse our experience with laparoscopic management of retroperitoneal injuries due to penetrating abdominal trauma (PAT) and to investigate its feasibility, safety and accuracy in haemodynamically stable patients. Over a 4-year period, patients approached laparoscopically with retroperitoneal injuries were analysed. Mechanism, location and severity of injuries were recorded. Surgical procedures, conversion rate and reasons for conversion and outcomes were described. Of the 284 patients with PAT, 56 patients had involvement of retroperitoneum. Stab wounds accounted 62.5% of patients. The mean Injury Severity Score was 7.4 (4-20). Among retroperitoneal injuries, the colon (27%) was the most commonly involved hollow viscera followed by duodenum (5%). The kidney (5%) and the pancreas (4%) were the injured solid organs. The conversion rate was 19.6% and was mainly due to active bleeding (73%). Significantly more patients with gunshot wound were converted to laparotomy (38% vs. 9%). Therapeutic laparoscopy was performed in 36% of patients. There were no recorded missed injuries or mortality. Five (9%) patients developed the Clavien-Dindo Grade 3 complications, three were managed with reoperation, one with drainage/debridement and one with endovascular technique. Laparoscopic management of retroperitoneal injuries is safe and feasible in haemodynamically stable patients with PAT. However, a high conversion rate indicates difficulties in managing these injuries. The requirements are the dexterity in laparoscopy and readiness to convert in the event of bleeding.

Esra Yıldızhan

2011-03-01

Full Text Available Although paracetamol and diclofenac sodium are most commonly used drugs and considered as safe, they are also frequently become a current issue with complications in therapeutic doses or overdose situations. Both drugs can cause bleeding disorders as a result of platelet dysfunction and can be presented as an atypical clinical situation such as subconjunctival hemorrhage. In these presented cases, the subconjunctival hemorrhage seen after ingestion of paracetamol and diclofenac sodium in toxic doses for the purpose of suicide, is considered as related with the bleeding disorder that is associated with drug side effect. For these patients who do not have any known co-morbidities, the reasons that can cause subconjunctival hemorrhage other than drugs such as trauma, infections, thrombocytopenia, malignant blood disorders, septicemia, hypertension, severe cough are excluded. Although hepatic and renal toxicities are commonly known side effects that are related with high doses of these drugs, in our cases there were not any impairment of hepatic or renal function tests other than compensated metabolic acidosis. In this report, the relationship of parasetamol and diclofenac sodium with bleeding disorders is discussed over two cases which presented as subconjunctival hemorrhage.

Lethal Ultra-Early Subarachnoid Hemorrhage Due to Rupture of De Novo Aneurysm 5 Months After Primary Aneurysmatic Subarachnoid Hemorrhage.

Walter, Johannes; Unterberg, Andreas W; Zweckberger, Klaus

2018-05-01

Approximately 1% of all patients surviving rupture of a cerebral aneurysm suffer from a second aneurysmatic subarachnoid hemorrhage later in their lives, 61% of which are caused by rupture of a de novo aneurysm. Latency between bleedings is usually many years, and younger patients tend to achieve better outcomes from a second subarachnoid hemorrhage. We report an unusual case of lethal ultra-early rupture of a de novo aneurysm of the anterior communicating artery only 5 months after the initial subarachnoid hemorrhage and complete coiling in a young, healthy male patient. Despite complete aneurysm obliteration, young age, and good recovery, patients may be subjected to secondary subarachnoid hemorrhages from de novo aneurysms after only a few months of the initial bleeding. Early-control magnetic resonance angiography might hence be advisable. Copyright © 2018 Elsevier Inc. All rights reserved.

2012-02-01

To describe a novel surgical technique for drainage of bullous serous and hemorrhagic choroidal detachments. A prospective, consecutive case series of 6 eyes with serous and/or hemorrhagic choroidal detachments secondary to intraocular surgery was documented to evaluate the feasibility of using the 25-gauge and 20-gauge transconjunctival trocar/cannula systems to drain choroidal detachments. Two eyes had expulsive hemorrhagic choroidal detachments and 4 eyes had serous choroidal detachments after glaucoma surgeries. A 25-gauge infusion line was placed in the anterior chamber. A 20-gauge (in eyes with hemorrhagic choroidal detachments) or a 25-gauge (in eyes with serous detachments) trocar/cannula system was inserted into the suprachoroidal space 7.0 mm from limbus. After drainage, the cannulas were removed and no sutures were placed. Pars plana vitrectomy was performed only in eyes with concomitant pathology that demanded the additional procedure. The primary outcome measure was presence of choroidal detachment at 1 week, 2 weeks, and 1 month postoperatively. Secondary outcome measures were visual acuity at 6 months and intraocular pressure at 1 week and 1, 3, and 6 months postoperatively. Drainage of hemorrhagic choroidal detachments resulted in resolution of the detachments by 1 month postoperatively. In eyes with serous detachments, resolution was achieved by 1 week postdrainage. In both groups, intraocular pressure increased to at least 10 mmHg by postoperative Week 1. The visual acuity improved in all eyes. No complications related to the transconjunctival technique were noted. Transconjunctival drainage of serous and hemorrhagic choroidal detachments seems to be a feasible and simple surgical option with minimal scleral and conjunctival damage. Pars plana vitrectomy may not be necessary when draining choroidal detachments in this manner.

To understand the structure and character of the right retroperitoneal space by analysis of the extension of retroperitoneal hematoma in patients with traumatic right renal injuries. We retrospectively reviewed CT scans of 13 patients with right retroperitoneal hematomas caused by right renal injury. At te renal level, we analyzed the relation of a hematoma contacting psoas muscle with other retroperitoneal compartmental hematomas. At the suprarenal level, a perirenal hematoma and a hematoma contacting the diaphragm were analyzed according to their relation with intrahepatic IVC and pericaval hematoma. Below renal hilar level, all hematomas contacting psoas muscle, observed in eight cases, were connected with retrorenal extension of anterior pararenal hematoma. At the suprarenal level, intrahepatic pericaval hematomas were not, in all 13 cases, connected with a hematoma contacting the diaphragm, but with a perirenal hematoma. At the upper suprarenal level, the only pericaval hematomas containing a medial component of perirenal hematoma extended superiorly to the upper one third of the tenth thoracic vertebral body. The anterior renal fascia envelops perirenal space except in its medial aspect. In the upper suprarenal region, the anterior and posterior planes of the anterior renal fascia unite to fuse with diaphragmatic fascia, but along the medial aspect they fuse with intrahepatic pericaval connective tissue and posteromedial diaphragm, respectively

Full Text Available Abstract Introduction Persistent lymphatic drainage following retroperitoneal lymph node dissection for testicular tumor is an uncommon complication. Case presentation We describe a 21-year old man of Caucasian origin who had metastatic non-seminomatous germ cell tumor of the testis, and underwent retroperitoneal lymph node dissection, nephrectomy and partial inferior vena cava excision for a residual mass. The patient subsequently developed persistent lymphatic drainage causing foot drop that eventually responded to conservative medical and surgical measures. Conclusion This postoperative condition usually responds well to conservative measures but has the potential for serious morbidity if it is not managed appropriately.

Diagnostic Value of Multislice Computed Tomography and Magnetic Resonance Imaging in the Diagnosis of Retroperitoneal Spread of Testicular Cancer: A Literature Review

International Nuclear Information System (INIS)

Hansen, J.; Jurik, A.G.

2009-01-01

Testicular cancer is the most frequent malignant disorder in men aged 15-35 years. Generally, diagnosing and follow-up include computer tomography (CT) examinations to detect possible retroperitoneal spread (abdomen and pelvis), resulting in at least eight CT examinations. This patient group is thereby exposed to a non-neglectable radiation dose, increasing the risk of future radiation-induced secondary cancer. This is especially problematic in potentially surgically cured patients with stage 1 testicular cancer. Thus, it can be beneficial to substitute CT with magnetic resonance imaging (MRI), provided there is valid evidence that the diagnostic value of MRI is at least comparable to current multislice CT (MSCT). The purpose of this study was to analyze whether there is evidence to recommend a substitution of MSCT with MRI in the diagnosis of retroperitoneal spread of testicular cancer. A literature search on the diagnostic accuracy, specificity, and sensitivity of MSCT and MRI in the diagnosis of retroperitoneal spread of testicular cancer was performed in the following databases: PubMed, EmBase, and ISI Web of Science. The search was limited to include the period from 2000 to September 2008, and to human and English-language publications. Forty-four publications were obtained for formal review (27 from PubMed, 15 from EmBase, two from ISI Web of Science). None of the publications reviewed encompassed diagnostic specificity and sensitivity of MSCT, and they lacked systematic comparison of MSCT and MRI. Only one study included sensitivity and specificity of MRI compared to single-slice CT. Both methods had a sensitivity and a specificity of approximately 70%. The literature review did not reveal valid data regarding diagnostic accuracy of MRI compared with MSCT for diagnosing retroperitoneal spread of testicular cancer. A prospective blinded comparative study is needed to provide valid evidence

Previous studies of pediatric intracerebral hemorrhage have investigated isolated intraparenchymal hemorrhage. We investigated whether detailed assessment of intraventricular hemorrhage enhanced outcome prediction after intracerebral hemorrhage. We prospectively enrolled 46 children, full-term to 17 years, median age 2.7 years with spontaneous intraparenchymal hemorrhage and/or intraventricular hemorrhage. Outcome was assessed with the King’s Outcome Scale for Childhood Head Injury. Twenty-six (57%) had intraparenchymal hemorrhage, 10 (22%) had pure intraventricular hemorrhage, and 10 (22%) had both. There were 2 deaths, both with intraparenchymal hemorrhage + intraventricular hemorrhage volume ≥4% of total brain volume. Presence of intraventricular hemorrhage was not associated with poor outcome, but hydrocephalus showed a trend (p=0.09) toward poor outcome. In receiver operating characteristic curve analysis, combined intraparenchymal hemorrhage + intraventricular hemorrhage volume also showed a trend toward better outcome prediction than intraparenchymal hemorrhage volume alone. Although not an independent outcome predictor, future studies should assess intraventricular hemorrhage qualitatively and quantitatively. PMID:22068828

Recently, the radiological concept of retroperitoneal interfascial planes has been widely accepted to explain the extension of retroperitoneal pathologies. This study aimed to explore embryologically based corroborative evidence, which remains to be elucidated, for this concept. Using serial or semi-serial transverse sections from 29 human fetuses at the 5th-25th week of fetal age, we microscopically observed the development of the retroperitoneal fasciae and other structures in the retroperitoneal connective tissue. A hypothesis for the formation of the interfascial planes was generated from the developmental study and analysis of retroperitoneal fasciae in computed tomography images from 224 patients. Whereas the loose connective tissue was uniformly distributed in the retroperitoneum by the 9th week, the primitive renal and transversalis fasciae appeared at the 10th-12th week, as previous research has noted. By the 23rd week, the renal fascia, transversalis fascia, and primitive adipose tissue of the flank pad emerged. In addition, the primitive lateroconal fascia, which runs parallel to and close to the posterior renal fascia, emerged between the renal fascia and the adipose tissue of the flank pad. Conversely, pre-existing loose connective tissue was sandwiched between the opposing fasciae and was compressed and narrowed by the developing organs and fatty tissues. Through this developmental study, we provided the hypothesis that the compressed loose connective tissue and both opposed fasciae compose the interfascial planes. Analysis of the thickened retroperitoneal fasciae in computed tomography images supported this hypothesis. Further developmental or histological studies are required to verify our hypothesis.

The Retrograde and Retroperitoneal Totally Laparoscopic Hysterectomy for Endometrial Cancer

Full Text Available Introduction. We retrospectively report our experience with the utilization of an original procedure for total laparoscopic hysterectomy based on completely retrograde and retroperitoneal technique for surgical staging and treatment of the endometrial cancer. The surgical, financial, and oncological advantages are here discussed. Methods. The technique used here has been based on a combination of a retroperitoneal approach with a retrograde and lateral dissection of the bladder and retrograde culdotomy with variable resection of parametrium. No disposable instruments and no uterine manipulator were utilized. Results. Intraoperative and postoperative complications were observed in 10% of the cases overall. Operative time length and mean haemoglobin drop value results were 129 min and 125 mL, respectively. Most patients were dismissed on days 3–5 from the hospital. Seventy-eight percent of the patients were alive with no evidence of disease at mean followup of 49 months. Conclusions. Our original laparoscopic technique is based on a retroperitoneal approach in order to rapidly control main uterine vessels coagulation, constantly check the ureter, and eventually decide type and site of lymph nodes removal. This procedure has important cost saving implications and the avoidance of uterine manipulator is of matter in case such as these of uterine malignancy.

Necrotizing fasciitis is a serious infection that originates in the subcutaneous tissues. Although many reports have been published about necrotizing infections of other anatomical sites, retroperitoneal necrotizing soft tissue infection is a rare entity that has been described in only a few case reports. The etiology and clinical course of retroperitoneal necrotizing fasciitis can be variable and it is often difficult to identify the etiology of the infective process. We report a 58-year-old man with rapidly progressive, gas-producing, necrotizing inflammation in the retroperitoneum, complicated with genital involvement resembling Fournier gangrene. The patient was managed successfully by aggressive drainage, debridement, and sequential laparotomies to track and control the extensive necrosis of the retroperitoneum and perineum, in addition to systemic care to control sepsis. After his general condition stabilized, early rectosigmoid adenocarcinoma was identified and resected curatively. He remained well at follow up, six months after discharge. In retrospect, the trigger of the disease process was unclear. Although it was believed possibly to be due to the colon lesion, adenocarcinoma of the rectosigmoid colon was identified and the patient was managed successfully. Similar to necrotizing infections at other anatomical sites, early diagnosis and timely surgical intervention and systemic antimicrobial therapy are mandatory for treating patients with retroperitoneal necrotizing fasciitis.

Patients with metastatic renal cell carcinoma have a reported 5-year survival of 0% to 20%. The ability to predict which patients would benefit from nephrectomy and interleukin-2 (IL-2) therapy before any treatment is initiated would be useful for maximizing the advantage of therapy and improving the quality of life. A retrospective analysis of the x-rays and charts of patients treated at the National Institutes of Health Surgery Branch between 1985 and 1996, who presented with metastatic renal cancer beyond the locoregional area and the primary tumor in place, was performed. Preoperative computerized tomography or magnetic resonance imaging, or radiological reports if no scans were available, were used to obtain an estimate of the volume of retroperitoneal lymphadenopathy. Operative notes were used to evaluate whether all lymphadenopathy was resected or disease left in situ, or if any extrarenal resection, including venacavotomy, was performed. Mean survival rate was calculated from the time of nephrectomy to the time of death or last clinical followup. If patients received IL-2 therapy, the response to treatment was recorded. Mean survival and response rate for IL-2 were compared among patients in 3 separate analyses. Patients without preoperatively detected lymphadenopathy were compared with those with at least 1 cm.3 retroperitoneal lymphadenopathy. Also, the patients who had detectable lymphadenopathy were divided into subgroups consisting of all resected, incompletely resected, unresectable and unknown if all disease was resected. Each subgroup was compared with patients without detectable preoperative lymphadenopathy. Patients with less than were compared to those with greater than 50 cm.3 retroperitoneal lymphadenopathy. Patients undergoing extrarenal resection at nephrectomy (complex surgery) due to direct invasion of the tumor into another intra-abdominal organ were compared with those undergoing radical nephrectomy alone, regardless of lymph node status

The aim of the present study was to investigate the rate of post-tonsillectomy hemorrhage (PTH) in a single institution and to evaluate the clinical risk factors for PTH. We reviewed the records of 692 patients who underwent tonsillectomy (TE) at Yokohama Minami Kyosai Hospital in Japan. PTH grades were grouped into three categories according to the severity of the hemorrhagic episode: (I) minimal hemorrhage that stopped after noninvasive treatment, (II) hemorrhage requiring treatment with local anesthesia, and (III) hemorrhage requiring reoperation under general anesthesia in the operating room. Clinical risk factors such as sex, age (adults vs. children), TE indication, surgeon's skill level, operative time, ligature type, and duration of antibiotic administration for PTH were investigated. Among the 692 patients, 80 (11.6%) showed PTH, with primary and secondary hemorrhage accounting for 1.6% and 10.0%, respectively. A category III PTH was observed in 18 patients; thus, the overall risk of reoperation was 2.6%. The PTH episode most frequently occurred on postoperative days 5 and 6. The frequency of PTH was significantly higher in male patients and in adults (Pdefinition of PTH. Clinical risk factors for PTH were adult age and male gender. The surgeon's skill level was an additional risk factor for category III PTH. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

2015-03-01

Although using fine needle cytology with aspiration (FNC-A) for establishing diagnoses in the retroperitoneal region has shown promise, there is scant literature supporting a role of non-aspiration cytology (FNC-NA) for this region. We assessed the accuracy and reliability of FNC-A and FNC-NA as tools for preoperative diagnosis of retroperitoneal masses and compared the results of both techniques with each other and with histopathology. Fifty-seven patients with retroperitoneal masses were subjected to FNC-A and FNC-NA. Smears were stained with May-Grunwald Giemsa and hematoxylin and eosin stain. An individual slide was objectively analysed using a point scoring system to enable comparison between FNC-A and FNC-NA. By FNC-A, 91.7% accuracy was obtained in cases of retroperitoneal lymph node lesions followed by renal masses (83.3%). The diagnostic accuracy of other sites by FNC-A varied from 75.0%-81.9%. By FNC-NA, 93.4% diagnostically accurate results were obtained in the kidney, followed by 75.0% in adrenal masses. The diagnostic accuracy of other sites by FNC-NA varied from 66.7%-72.8%. Although both techniques have their own advantages and disadvantages, FNC-NA may be a more efficient adjuvant method of sampling in retroperitoneal lesions.

Retrograde ejaculation is a frequent and permanent complication after bilateral retroperitoneal lymphadenectomy (RPLND). Seminal emission and ejaculation are primarily under sympathetic control. Several studies after RPLND in patients with nonseminomatous testis cancer proved the role of preservation of the efferent fibers originating from the lumbar sympathetic ganglia. Based on the results of anatomical studies, a modified unilateral operative technique and nerve-sparing approach permit to preserve normal anterograde ejaculation without reduction of long-term survival.

Retroperitoneal necrotizing fasciitis presenting with peritonism in a 33-year-old Nepalese man: a case report

2012-02-01

Full Text Available Abstract Introduction Retroperitoneal necrotizing fasciitis is a rare, fulminant, and potentially lethal complication of intra-abdominal suppuration. A retroperitoneal origin is very rare and very few cases have been reported in the literature. To the best of our knowledge, this case is only the fourth case reported of successful management following retroperitoneal necrotizing fasciitis. Case presentation A 33-year-old Tamang man presented to our facility with a history of five days of fever and vomiting and eight days of severe left loin pain. On examination, he had features of peritonism. A laparotomy was performed, revealing extensive necrotizing fasciitis of the retroperitoneum extending to the anterior abdominal wall. Our patient survived following extensive debridement of the necrotic tissues and supportive care. Conclusions Retroperitoneal necrotizing fasciitis can rarely present with features of peritonism, and hence should be included as a possible differential diagnosis for anyone presenting with peritonism. Although a fatal condition, early intervention and aggressive management can save the life of a patient.

Primary Retroperitoneal Mucinous Cystadenocarcinoma: 5th Male Case in the Literature

Full Text Available Retroperitoneal primary mucinous tumor is an extremely rare malignancy. To date, only 52 cases of primary retroperitoneal mucinous cystadenocarcinoma (PRMC have been reported in the literature, with the majority being women. Our patient is the 5th known male case. A 57-year-old male patient presented with a two year history of an undefined abdominal pain.Computed tomography demonstrated a 12 x 9.5 cm cystic mass lesion extending superiorly from right iliac fossa, while localizing below the abdominal wall and close to the psoas muscle. According to the laparotomy, iliopsoas muscle was infiltrated by the mass in the retroperitoneal region. Pathological diagnosis was mucinous cystadenocarcinoma . The asymptomatic patient was followed up without applying an adjuvant chemotherapy, since the clinical course of the tumor is known to be slow and postoperative therapy is not recognized as a standardized treatment. The clinical course of PRMC is generally indolent, however, it may manifest an aggressive course, as well. It has no definitive and clear pathogenesis. The treatment is contentious, as well. Diagnosis and treatment require surgical excision but data on adjuvant chemotherapy is limited.

• To report our experience with retroperitoneal laparoscopic dismembered pyeloplasty for pelvi-ureteric junction (PUJ) obstruction in children. • Between March 2007 and December 2009, 38 children with PUJ obstruction (mean age 8.3 years, range 3-14) underwent retroperitoneal laparoscopic dismembered pyeloplasty. • A ureteric catheter was inserted into the mid-ureter cystoscopically. During pyeloplasty, the proximal end of the ureteric catheter was extracorporeally sutured to the distal end of the JJ stent with silk. • The ureteric catheter was then pulled down and the stent was pulled antegrade into the ureter and bladder. • The approach was retroperitoneal in all patients except one who required open conversion. The overall mean operative time was 162 min (range 145-210 min) and this appeared to decrease with experience. Mean hospital stay was 4 days (range 3-7 days). • Mean follow-up was 20.2 months (range 6-32 months). Satisfactory drainage with decreased hydronephrosis was documented in all patients on ultrasonography and intravenous urography. • Our study shows that retroperitoneal laparoscopic dismembered pyeloplasty is a feasible and effective alternative to open pyeloplasty with a relatively minimal complication rate in children 3 years of age and older, but it should be undertaken by experienced laparoscopic surgeons. © 2011 THE AUTHORS.

2012-12-01

Optional inferior vena cava (IVC) filters are being increasingly used for protection against pulmonary embolism in patients with deep vein thrombosis where anticoagulation is contraindicated. We describe two cases during retroperitoneal surgery where the IVC filters were found to have perforated the cava wall and were subsequently removed intra-operatively. Cava wall penetration by filter limbs poses a significant danger during retroperitoneal lymph node dissection and filters should be removed preoperatively.

Acute gaseous peritonitis after rupture of a retroperitoneal rectal diverticulum in a dog.

2008-07-01

An 11-year-old, entire male coton de tulear was presented on emergency with acute and severe depression, acute abdominal pain and vomiting of 24 hours duration. Historical complaints included right perineal swelling, dyschezia and tenesmus of 18 months duration. Abdominal ultrasonography and radiography suggested a pneumoperitoneum and positive-contrast colonography showed leakage of contrast medium into the caudal abdomen and the presence of a large retroperitoneal pouch. Exploratory laparotomy allowed the visualisation of faecal leakage from the retroperitoneal space into the peritoneal cavity. Using a perineal approach, a large necrotised rectal diverticulum filled with faeces was found over the retroperitoneal structures. A standard herniorrhaphy was then performed. The dog recovered uneventfully and dyschezia did not recur at the nine month follow-up. Rectal diverticulum rupture associated with peritonitis has not been described in the veterinary literature, to the authors' knowledge, and should be considered as a rare differential diagnosis in dogs being presented with gaseous peritonitis.

Retroperitoneal disorders associated with IgG4-related autoimmune pancreatitis

Science.gov (United States)

Hara, Noboru; Kawaguchi, Makoto; Takeda, Keisuke; Zen, Yoh

2014-01-01

IgG4-related autoimmune pancreatitis is frequently accompanied by relevant lesions in the genitourinary tract and retroperitoneal organs, which cause various clinical problems, ranging from non-specific back pain or bladder outlet obstruction to renal failure. The diagnosis of IgG4-related retroperitoneal fibrosis requires a multidisciplinary approach, including serological tests, histological examination, imaging analysis, and susceptibility to steroid therapy. Radiological examinations are helpful to diagnose this condition, but surgical resection is occasionally unavoidable to exclude malignancy, particularly for patients with isolated retroperitoneal involvement. Steroid therapy is the treatment of choice for this condition, the same as for other manifestations of IgG4-related disease. For patients with severe ureteral obstruction, additional ureteral stenting needs to be considered prior to steroid therapy to preserve the renal function. Some papers have suggested that IgG4-related disease can affect male reproductive organs including the prostate and testis. IgG4-related prostatitis usually causes lower urinary tract symptoms, such as dysuria and pollakisuria. Patients sometimes state that corticosteroids given for IgG4-related disease at other sites relieve their lower urinary tract symptoms, which leads us to suspect prostatic involvement in this condition. Because of the limited number of publications available, further studies are warranted to better characterize IgG4-related disease in male reproductive organs. PMID:25469023

Retroperitoneal unicentric Castleman's disease (giant lymph node hyperplasia: case report

Directory of Open Access Journals (Sweden)

Jaques Waisberg

Full Text Available CONTEXT AND OBJECTIVE: Castleman's disease, or giant lymph node hyperplasia, is a rare disorder of the lymphoid tissue that causes lymph node enlargement. It is considered benign in its localized form, but aggressive in the multicentric type. The definitive diagnosis is based on postoperative pathological findings. The aim here was to describe a case of retroperitoneal unicentric Castleman's disease in the retroperitoneum. CASE REPORT: A 61-year old white male with weight loss and listlessness presented with moderate arterial hypertension and leukopenia. Abdominal tomography revealed a 5 x 4 x 5 cm oval mass of low attenuation, with inner calcification and intense enhancement on intravenous contrast, located in the retroperitoneal region, between the left kidney and the aorta, at the renal hilus. Exploratory laparotomy revealed a non-pulsatile solid oval mass situated in the retroperitoneum, adjacent to the left renal hilus. The retroperitoneal lesion was removed in its entirety. Examination of frozen samples revealed benign lymph node tissue and histopathological examination of the surgical sample revealed hyaline-vascular giant lymph node hyperplasia (Castleman's disease. The patient was discharged on the 12th day without significant events. Two months after the operation, the patient was readmitted with severe cardiac insufficiency, acute renal failure and bronchopneumonia, which progressed to acute respiratory insufficiency, sepsis and death.

Chryseobacterium meningosepticum Sepsis Complicated with Retroperitoneal Hematoma and Pleural Effusion in a Diabetic Patient

Directory of Open Access Journals (Sweden)

Shou-Wu Lee

2008-09-01

Full Text Available Intra-abdominal infection due to Chryseobacterium meningosepticum is rare, and bacteremia complicated with pleural effusion and retroperitoneal hematoma caused by C. meningosepticum has not been reported previously. A 57-year-old diabetic man presented with bacteremia with retroperitoneal abscess and pleural effusion caused by C. meningosepticum on the 12th day of hospitalization. His clinical condition improved after antimicrobial therapy with levofloxacin and rifampin, debridement of the retroperitoneal hematoma and left-side chest tube insertion. Antibiotics were administered for 1 month, and he was later transferred to a local respiratory care ward under afebrile condition. C. meningosepticum should be included in the list of suspected nosocomial infections, especially in patients with immunocompromised status. Administration of appropriate antibiotics, such as quinolone, minocycline, trimethoprim-sulfamethoxazole or rifampin, and treatment of local infection improve the clinical outcome of patients with C. meningosepticum infection.

2015-02-01

Fenestrations of the posterior communicating artery (PCoA) are extremely rare. Associated aneurysms have only been documented three times in the literature, and none associated with a subarachnoid hemorrhage. We describe a 52-year-old female who presented with a subarachnoid hemorrhage secondary to a ruptured saccular aneurysm at the proximal limb of a fenestrated right PCoA. The patient was also found to have bilateral middle cerebral artery (MCA) aneurysms. Surgical management included surmising the etiology of the subarachnoid hemorrhage with subsequent clipping of both the right PCoA and MCA aneurysm. The potential embryological mechanisms leading to a PCoA fenestration are discussed.

There are very few published reports implicating enoxaparin as a factor in retroperitoneal hematoma. We report a patient who developed a retroperitoneal hematoma after using enoxaparin for paroxysmal atrial fibrillation. A 72 year old man was admitted with a history of low back pain, radiating beyond the back to the buttocks. His medical history was positive for bilateral knee osteoarthritis. On his physical examination his vital signs were: temperature 36.8, blood pressure 100/70 mm Hg, pulse 72/min, respiratory rate 16/min. X-ray of both the knees showed bilateral osteoarthritic changes. Computerized tomography scan of the spine showed lumbar spinal stenosis and he was referred to a Neurosurgeon, who finds the patient not fit surgical intervention. ECG showed atrial fibrillation. He was given enoxaparin one mg/kg every 12 hour and digoxin. Abdominal computed tomography revealed a right retroperitoneal hematoma and no aortic aneurysm was noted and enoxaparin and rofecoxib were discontinued. His general condition improved. The factors that increase the risk of bleeding in patients receiving enoxaparin are use of high doses of enxaparin, advanced stage, renal impairment, and the concomitant use of drugs affecting hemostasis. Retroperotoneal hematoma should be considered in the different diagnosis in patients receiving enoxaparin and experiencing unexplained decreases in hemoglobin and hematocrit. In the order of precedence of radiologic diagnostic procedures for fast diagnosis of a retroperitoneal hematoma, abdominal CT-scan is the preferred method

Surgery is potentially curative for primary non-metastatic retroperitoneal soft tissue sarcomas (RPS), although patients remain at risk for local recurrence. To reduce this risk, the addition of radiotherapy to radical surgery may be considered. Nevertheless, level I evidence to support radiotherapy is currently lacking. The results from the EORTC-STBSG 62092-22092 studying this question are awaited. This manuscript addresses issues to consider when radiation-oncologists engage in a multidisciplinary treatment approach for RPS patients, including radiotherapy. © 2017 Wiley Periodicals, Inc.

We report neuroimaging findings of intracranial hemorrhage and cerebral edema in an infant with obtundation and seizures, initially suspected to be secondary to non-accidental trauma but finally attributed to hypernatremic dehydration. Neuroimaging findings due to hypernatremic dehydration have not been previously described in the radiologic literature. Hypernatremia should be included in the differential diagnosis of intracranial hemorrhage in the infant without evidence of nonaccidental trauma. (orig.). With 1 fig

Objective: To investigate the clinical significance of peritoneal and retroperitoneal edema in patients with de-compensated cirrhosis (DCC). Methods: Forty-four patients, were identified with DCC on the basis of clinic and laboratory examinations, except the cases with mesenteric, omental and retroperitoneal edema caused by inflammatory and malignant diseases. The diagnosis of edema depended upon hyper-density in peritoneal and retroperitoneal. The degree of edema was divided into minor, middle, and sever types based on the extent of edema. Ascites, varices, serum albumin (ALB) levels, and hyaluronic acid (HA) levels were also documented. Correlations between the laboratory and CT findings were analyzed. Results: The severity of peritoneal edema was correlated with decreasing serum ALB (r s = 0.7088, P s = 0.5294, P s = 0.5440, P s = 0.1335, P > 0.05). Conclusion: CT findings of the edema in peritoneal and retroperitoneal may indicate the severity of the liver cirrhosis

Retroperitoneal fibrosis (RPF) is a rare condition of unclear etiology. It can cause ureteral obstruction. We present the unique case of a 54 years old female, who initially presented with spontaneous perforation of the cecum. Upon exploring the abdomen, the classical glistening white, unyielding retroperitoneal fibrosis was encountered. A right hemicolectomy was performed.Subsequently, the patient presented with bilateral ureteral obstruction, and later on with small bowel obstruction. Ureteral obstruction was treated with stents,and small bowel obstruction was treated with bypass.To our knowledge no case of idiopathic RPF presenting with features of both bilateral ureteral and small bowel obstruction has been reported in the literature.

In 1938, Turner described a clinical entity in phenotype females characterized by sexual infantilism, congenital webbed neck and cubitus valgus. After then, the occurrence of renal anomalies in patients with Turner's syndrome has been recognized. Associated crossed fused renal ectopia is very rare. Primary retroperitoneal teratoma is also rare and usually during childhood. The authors report a case of primary retroperitoneal teratoma and crossed fused renal ectopia with Turner's syndrome (mosaic type). The clinical, pathological and radiographical findings are reviewed.

Dengue is a common viral infection worldwide with presentation varying from clinically silent infection to dengue fever, dengue hemorrhagic fever, and severe fulminant dengue shock syndrome. Neurological manifestation usually results from multisystem dysfunction secondary to vascular leak. Presentation as hemorrhagic encephalitis is very rare. Here we present the case of a 13-year-old female admitted with generalized tonic clonic seizures. Plain computed tomography (CT) scan of head revealed hypodensities in bilateral deep gray matter nuclei and right posterior parietal lobe without any hemorrhage. Cerebrospinal fluid (CSF) and serology were positive for IgM and IgG antibodies to dengue viral antigen. Contrast-enhanced magnetic resonance imaging (MRI) revealed multifocal T2 and fluid attenuated inversion recovery (FLAIR) hyperintensities in bilateral cerebral parenchyma including basal ganglia. No hemorrhage was seen. She was managed with steroids. As her clinical condition deteriorated, after being stable for 2 days, repeat MRI was done which revealed development of hemorrhage within the lesions, and diagnosis of acute hemorrhagic encephalitis of dengue viral etiology was made

A Case of Segmental Arterial Mediolysis Presenting as Mucosal Gastric Hematoma

Directory of Open Access Journals (Sweden)

Shunsuke Sakuraba

2017-01-01

Full Text Available Background. Although segmental arterial mediolysis (SAM has been increasingly recognized as arteriopathy and there are some case reports about SAM, it is still very rare. It is characterized clinically by aneurysm, dissection, stenosis, and occlusion within splanchnic arterial branches, causing intra-abdominal hemorrhage or bowel ischemia. Mortality is as high as 50% in acute events. Case Presentation. A 51-year-old man was referred to our hospital with hematemesis. Gastroscopy revealed a submucosal-like tumor on the posterior wall of gastric angle with ulceration. Computed tomography indicated a tumor measuring 65×50 mm in the stomach, which was suspected to have invaded into the pancreas. Significant hematemesis recurred; the patient developed shock and underwent emergency distal gastrectomy, distal pancreatectomy, and splenectomy. The pathology and the clinical course were compatible with SAM splenic artery rupture causing retroperitoneal hemorrhage that penetrated into the stomach. After that surgery, aneurysm of common hepatic artery ruptured and coil embolization was performed. Conclusion. SAM is an important cause of intra-abdominal or retroperitoneal hemorrhage in patients without underlying disease. SAM typically presents as intra-abdominal hemorrhage, but, in this case, the retroperitoneal hemorrhage penetrated into the stomach and it looked like a submucosal tumor.

Management of metastatic retroperitoneal sarcoma: a consensus approach from the Trans-Atlantic Retroperitoneal Sarcoma Working Group (TARPSWG).

Science.gov (United States)

2018-04-01

Retroperitoneal sarcoma (RPS) is a rare disease accounting for 0.1%-0.2% of all malignancies. Management of RPS is complex and requires multidisciplinary, tailored treatment strategies at all stages, but especially in the context of metastatic or multifocal recurrent disease. Due to the rarity and heterogeneity of this family of diseases, the literature to guide management is limited. The Trans-Atlantic Retroperitoneal Sarcoma Working Group (TARPSWG) is an international collaboration of sarcoma experts from all disciplines convened in an effort to overcome these limitations. The TARPSWG has compiled the available evidence surrounding metastatic and multifocally recurrent RPS along with expert opinion in an iterative process to generate a consensus document regarding the complex management of this disease. The objective of this document is to guide sarcoma specialists from all disciplines in the diagnosis and treatment of multifocal recurrent or metastatic RPS. All aspects of patient assessment, diagnostic processes, local and systemic treatments, and palliation are reviewed in this document, and consensus recommendations provided accordingly. Recommendations were guided by available evidence, in conjunction with expert opinion where evidence was lacking. This consensus document combines the available literature regarding the management of multifocally recurrent or metastastic RPS with the practical expertise of high-volume sarcoma centers from multiple countries. It is designed as a tool for decision making in the complex multidisciplinary management of this condition and is expected to standardize management across centers, thereby ensuring that patients receive the highest quality care.

To describe cases of obstetric hemorrhage that have called for selective intra-arterial embolization and the different embolization techniques used. To assess the clinical outcomes and postprocedural fertility. We studied 27 women with obstetric hemorrhage. In 24 patients, embolization was performed by catheterizing both uterine arteries and in 2 patients only one uterine artery was catheterized (pseudoaneurysm). The materials used for embolization consisted of Spongostan in 17/27, particles in 9/27, and coils in 1/27. Clinical follow-up included an analysis of early and late complications and of postprocedural fertility. Hemorrhage was classified as primary (25/27) or secondary (2/27). The cause of bleeding was vaginal delivery (20), cesarean sections (5), abortion (1), and cervical ectopic pregnancy (1). The initial technical success rate was 100% and the clinical success rate was 92.6% (25 of the 27 patients). Bleeding ceased and the outcome was satisfactory in 25 patients. During clinical follow-up ranging from one to seven years, 23 patients had normal menstruation and 6 patients completed 7 full-term pregnancies. Intra-arterial embolization for obstetric hemorrhage leads to good outcomes and few complications and it preserves fertility. Copyright © 2011 SERAM. Published by Elsevier Espana.

Patients with a primary pure seminoma in the testis who have elevated serum alpha-fetoprotein are rare and should be treated as patients with nonseminomatous germ cell tumors. However, nonpalpable testicular tumors in this condition have never been reported. We describe a case of nonpalpable pure testicular seminoma with elevated serum alpha-fetoprotein presenting retroperitoneal metastasis. A 29-year-old Asian man was referred to our hospital with right flank pain. Computed tomography showed a mass located between his aorta and inferior vena cava, but a testicular tumor was not detected. His serum levels of lactate dehydrogenase, alpha-fetoprotein, and DUPAN-2 were high. Although no tumor or nodule was palpable in his testis, ultrasonography revealed multiple low echoic lesions in his right testicular parenchyma. He was diagnosed with right testicular cancer with retroperitoneal lymph node metastasis and underwent right high orchiectomy. A pathological examination revealed pure seminoma and no nonseminomatous components were found in the specimen. Three courses of induction systemic chemotherapy (cisplatin, etoposide, and bleomycin) normalized his serum alpha-fetoprotein and DUPAN-2 levels. Three additional courses of chemotherapy (etoposide and bleomycin) were performed, and treatment was completed with laparoscopic retroperitoneal lymph node dissection. Pathology of the dissected specimen showed fibrous and necrotic tissue with no viable cells. He is alive without recurrence 54 months after orchiectomy. We report a case of pure testicular seminoma with elevated serum alpha-fetoprotein and DUPAN-2 presenting retroperitoneal metastasis. We recommend an ultrasound examination of bilateral testes when large retroperitoneal tumors are detected in young men, even if a mass is not palpable in the scrotum.

Concomitant acute ischemic lesions are detected in up to a quarter of patients with spontaneous intracerebral hemorrhage (ICH). Influence of bleeding pattern and intraventricular hemorrhage (IVH) on risk of ischemic lesions has not been investigated. Retrospective study of all 500 patients enrolled in the CLEAR III randomized controlled trial of thrombolytic removal of obstructive IVH using external ventricular drainage. The primary outcome measure was radiologically confirmed ischemic lesions, as reported by the Safety Event Committee and confirmed by two neurologists. We assessed predictors of ischemic lesions including analysis of bleeding patterns (ICH, IVH and subarachnoid hemorrhage) on computed tomography scans (CT). Secondary outcomes were blinded assessment of mortality and modified Rankin scale (mRS) at 30 and 180 days. Ischemic lesions occurred in 23 (4.6%) during first 30 days after ICH. Independent risk factors associated with ischemic lesions in logistic regression models adjusted for confounders were higher IVH volume (p = 0.004) and persistent subarachnoid hemorrhage on CT scan (p = 0.03). Patients with initial IVH volume ≥ 15 ml had five times the odds of concomitant ischemic lesions compared to IVH volume < 15 ml. Patients with ischemic lesions had significantly higher odds of death at 1 and 6 months (but not poor outcome; mRS 4-6) compared to patients without concurrent ischemic lesions. Occurrence of ischemic lesions in the acute phase of IVH is not uncommon and is significantly associated with increased early and late mortality. Extra-parenchymal blood (larger IVH and visible subarachnoid hemorrhage) is a strong predictor for development of concomitant ischemic lesions after ICH.

The purpose of this study was to introduce a new method for locating the renal artery during retroperitoneal laparoscopic renal surgery. The medial arcuate ligament (MAL) is a tendinous arch in the fascia under the diaphragm that arches across the psoas major muscle and is attached medially to the side of the first or the second lumbar vertebra. The renal artery arises at the level of the intervertebral disc between the L1 and L2 vertebrae. We evaluate the role of the MAL that serves as an anatomic landmark for locating the renal artery during retroperitoneal laparoscopic renal surgery. There is a reproducible consistent anatomic relationship between MAL and the renal artery in 210 cases of retroperitoneal laparoscopic renal surgery. Two main types of the MAL, the "narrow arch" and the "fascial band" types, can be observed. MAL can serve as an accurate and reproducible anatomic landmark for the identification of the renal artery during retroperitoneal laparoscopic renal surgery.

Fourteen cases of cerebellar hemorrhage were analysed from the point of CT-scan, and the following results were obtained. 1. The number of cases of cerebellar hemorrhage forms 4.4% of that of total intracranial hemorrhage. 2. Most of the cerebellar hematomas extend upward. Downward extension is rare. 3. In acute dead cases hematomas are 5 cm or more in diameter and lie over bilateral hemispheres with the extension to third or fourth ventricles in CT-scans. 4. Slowly progressive cases are detriorated by the secondary hydrocephalus. 5. In mild cases hematomas are 3cm or less in diameter on CT-scans and the hematoma evacuation is not indicated for these cases. 6. The shunt operation alone is sufficient for the life saving of the slowly progressive cases, but the hematoma evacuation is indicated in these cases if the functional prognosis is taken into consideration. 7. Immediate hematoma evacuation together with the ventricular drainage is considered to be effective for the life saving of the acute fulminant cases.

Malignant nerve sheath tumours (MPNST) are rare neoplasias and retroperitoneal cases are fairly rare and clinically difficult to be detected, but they are very agressive neoplasias. MPNST are frequently seen in head, neck and upper extremities. In patients with NF1; MPNST, a poor-prognostic lesion, may result from a malignant degeneration of a former plexiform neurofibroma. It is necessary to be aware of a potential malignancy in patients diagnosed with plexiform neurofibroma. We present a 21-year-old female with a diagnosis of MPNST. The patient was admited to the hospital because of a tumour in the subcutaneous region on her left buttock. The surgeon's clinical diagnosis was lipoma. After the pathological examination of biopsy specimen, the lesion was identified as "plexiform neurofibroma" and then the patient was diagnosed with Neurofibromatosis Type 1 (NF1). Simultaneously, another mass on the retroperitoneal region was identified as malignant peripheral nerve sheath tumour (MPNST).

Full Text Available Primitive neuroectodermal tumor (PNET is a rare “small round blue cell tumor” that is diagnosed by open biopsy or percutaneous biopsy of the lesion under radiologic guidance. In this case report, we present a novel approach to the diagnosis of a retroperitoneal PNET by endoscopic ultrasound- (EUS- guided fine needle aspiration (FNA. A 35-year-old man presented with the history of left-sided flank pain and swelling of 3-weeks duration. Computerized tomography (CT scan of his abdomen revealed a 12.8 × 13 × 12.5 cm cystic and solid mass arising from the retroperitoneum and displacing the third and fourth portions of the duodenum. He underwent EUS which revealed a well-circumscribed heterogeneous mass abutting the inferior portion of the stomach. EUS-FNA of the mass revealed malignant cells consistent with primitive neuroectodermal tumor (PNET/Ewing's sarcoma. EUS-guided FNA is an appropriate technique for diagnosing retroperitoneal PNET/Ewing's sarcoma.

These lesions, which are characterized by large and heterogeneous retroperitoneal masses, are uncommon and usually diagnosed late. Intravenous contrast enhanced computerized tomography is a useful method for the evaluation of these tumors and their relationship with adjacent structures. (author)

The role of CT in pelvic fracture. CT finding of retro-peritoneal hematoma and indication of transcatheter arterial embolization

1998-01-01

Although retro-peritoneal hematoma accompanying a pelvic fracture has been treated by arterial ligation formerly, it is associated with a high mortality rate and a transcatheter arterial embolization has now become the first choice of treatment. Meanwhile, the usefulness of computed tomography (CT) in traumatized patient has been reported frequently. Our hospital also employs CT positively as an examination following plain radiography in the cases with pelvic fracture. However, while indication of angiography is seen in several reports, the amount of retro-peritoneal hematoma as an index has not been reported. In the present study, we examined 112 patients given CT at the time of examination at the emergency center of our hospital between April 1, 1988, and June 30, 1997, and classified the amount of retro-peritoneal hematoma on CT into 5 groups to discuss indication of angiography. In the cases with moderate or massive amount of retro-peritoneal hematomas, cases with shock state exceeded 60% and the amount of hematoma was considered to reflect the circulation profile to a certain extent. As the amount of retro-peritoneal hematoma increased, the number of cases given embolization also increased; embolization was performed in 29 cases (61.7%) among those which had moderate or massive amount of hematoma. From the above findings, it was predicted that the amount of retro-peritoneal hematoma could be one of the deciding factors for indication of angiography. However, as there are cases falling into a shock state due to gradual increase of hematoma or associated with injuries in other organs, careful observation is needed for the cases judged out of indication.

Hydronephrosis is a common disease in children and may be caused by ureteral fibroepithelial polyps (UFP). Ureteral fibroepithelial polyps are rare in children and are difficult to precisely diagnose before surgery. Surgical treatment for symptomatic UFP is recommended. At the present institution, retroperitoneal laparoscopy has been used to treat five boys with UFP since 2006. To highlight the significance of UFP as an etiological factor of hydronephrosis in children and evaluate the applicative value of retroperitoneal laparoscopy in the treatment of children with UFP. Between 2006 and 2013 five boys underwent retroperitoneal laparoscopy at the present institution. They were identified with UFP by review of the clinical database. Detailed data were collected, including: radiographic studies, gross anatomical pathology, and pathology and radiology reports. All boys had been followed up at least every 6 months. All of the boys were aged between 7 and 16 years (mean 9.8 years). The main symptoms were flank pain (all five) and hematuria (three). Radiographic examination showed that all of the boys presented with incomplete ureteral obstruction and hydronephrosis. The ureteral fibroepithelial polyps were located near the left UPJ or the left proximal ureter. All of the boys had the UFP removed: three underwent retroperitoneal laparoscopic dismembered Anderson-Hynes pyeloplasty and polypectomy, and two had retroperitoneal laparoscopic ureteral anastomosis. These polyps were all on the left side and between 15 and 35 mm in length (mean 22 mm) (Figure). All of the boys recovered well and were discharged from hospital. The postoperative histological report confirmed that the specimens were UFP. Hydronephrosis was periodically assessed by ultrasonography (using the same method as pre-surgical ultrasonography) after surgery. Mean follow-up was 33 months (range 6-58 months) and no complications were found afterwards. Ureteral fibroepithelial polyps are rare but rather

The purpose of this study was to investigate retrospectively the clinical procedural performance of CT-guided needle biopsy for retroperitoneal lesions. CT-guided needle biopsy was performed in 74 consecutive patients (M:F = 44:30; mean age, 59.7 years) with retroperitoneal lesions between April 1998 and June 2009. The target lesion ranged from 1.5 to 12.5 cm in size. The biopsy access path ranged from 3.5 to 11.5 cm in depth. A biopsy specimen was obtained using an 18-gauge core needle under a CT or CT-fluoroscopy guidance and with the patient under local anesthesia. The histopathological diagnoses from the biopsies were obtained. The diagnostic confirmation of the subtype of lymphoma was evaluated. Satisfactory biopsy samples were obtained in 73 (99%) of 74 patients and a pathological diagnosis was made in 70 (95%) of 74 patients. Sixty three lesions were malignant (45 lymphomas, nine primary tumors, nine lymph node metastases) and seven were benign. The subtype of lymphoma was specified in 43 (96%) of 45 patients who were diagnosed with lymphoma. Analysis of the value of CT-guided biopsy in this series indicated 63 true positives, zero false positive, six true negatives and five false negatives. This test had a sensitivity of 93%, a specificity of 100% and an accuracy of 93%. No major complications were seen and minor complications were noted in seven patients (five with local hematomas, two with transient pain at the puncture site). CT-guided needle biopsy for retroperitoneal lesions is highly practical and useful, and particularly for determining the subtypes in patients with lymphoma.

The purpose of this study was to evaluate the safety and precision of MRI-guided biopsies of retroperitoneal space-occupying tumors in an open low-field system. In 30 patients with indistinct retroperitoneal tumors [paraaortic lesion (n=20), kidney (n=2), suprarenal gland (n=3) and pancreas (n=5)] MR-guided biopsies were performed using a low-field system (0.2 T, Magnetom Concerto, Siemens, Germany). For the monitoring of the biopsies T1-weighted FLASH sequences (TR/TE=160/5 ms; 90 ) were used in all patients and modified FLASH sequences (TR/TE=160/13 ms; 90 ) in ten patients. After positioning of the needle in the tumors 114 biopsy specimens were acquired in coaxial technique with 16-gauge cutting needles (Somatex, Germany). The biopsies were successfully performed in all patients without vascular or organ injuries. The visualization of the aortic blood flow with MRI facilitated the biopsy procedures of paraaortic lesions. The size of the lesions ranged from 1.6 to 7.5 cm. The median distance of the biopsy access path was 10.4 cm. Adequate specimens were obtained in 28 cases (93.3%) resulting in a correct histological classification of 27 lesions (90%). In conclusion, MR-guided biopsies of retroperitoneal lesions using an open low-field system can be performed safely and accurately and is an alternative to CT-guided biopsies. (orig.)

BACKGROUND: Ganglioneuroma is a rare tumour of neural crest origin, which arises from maturation of a neuroblastoma. While previously considered to be non-functioning, they are now known to be frequently endocrinologically active. AIMS AND METHODS: We report a case of a massive retroperitoneal ganglioneuroma presenting with small bowel obstruction in an adult, 18 years after initial diagnosis. Urinary dopamine levels were elevated, but other catecholamines were within normal limits. This is the first report in the English-language literature of a retroperitoneal ganglioneuroma presenting with or causing intestinal obstruction. We also review the metabolic, radiological, and histological features of these tumours. Relevant publications were identified from a Medline search using the MeSH headings \\'ganglioneuroma\\

Aim: To determine the sensitivity of magnetic resonance imaging (MRI) in the detection of retroperitoneal lymph nodes in patients with testicular germ cell tumours (TGCT). Methods and materials: A prospective study of 52 patients (mean age 34 years, range 18-54 years) was performed. Imaging of the retroperitoneum was performed using multidetector computed tomography (CT) and 1.5 T MRI systems. The CT and MRI images were read independently by three observers. The number, size, and site of enlarged nodes ({>=}10 mm maximum short axis diameter) were recorded. Retroperitoneal nodal detection on MRI was compared to CT. Results: Twenty-two (42%) of the 52 patients had no retroperitoneal disease; in remaining 30 patients 51 enlarged nodes were identified. On a per patient basis readers 1, 2, and 3 identified nodal disease in 28 of 29, 29 of 30, and 24 of 30 patients, respectively, using MRI compared to CT. Thus for experienced radiologists (readers 1 and 2) MRI is comparable to CT for nodal detection (i.e., this study excludes MRI being inferior to CT with 80% power and 5% type 1 error). Conclusion: MRI offers an alternative method for staging the retroperitoneum in young patients being followed for TGCT and has the major advantage of avoiding exposure to ionizing radiation.

To present our single-center experience with retroperitoneal laparoscopic partial nephrectomy (LPN) and retroperitoneal laparoscopic radical nephrectomy (LRN) for T1 renal hilar tumors and evaluate which one is better. A retrospective review of 63 patients with hilar tumors undergoing retroperitoneal LPN or LRN was performed. The perioperative characteristics, change in estimated glomerular filtration rate (eGFR) from baseline to month 3, and oncologic outcomes were summarized. In total, 25 patients underwent LPN, and 38 patients underwent LRN. The mean tumor size in the LPN and LRN groups was 4.5 and 4.9 cm, respectively. The mean operation time was longer in the LPN group than that in the LRN group (212.5 minutes versus 160.7 minutes, respectively; P  .05). In experienced hands, although retroperitoneal LRN can result in shorter operation times and shorter lengths of stay, retroperitoneal LPN can preserve renal function better than LRN. Retroperitoneal LPN should be the priority in selected patients with T1 renal hilar tumors, especially for patients with renal insufficiency.

PARAVAGINAL AND RETROPERITONEAL HAEMATOMA POST PARTUM

Full Text Available Background. Postpartum haemorrhage from ruptured tissues can usually be diagnosed and managed properly. A problem exists with the occult haemorrhage without evident tissue trauma in which case a haematoma develops. Methods. After a normal delivery of the 41 years old secundipara after a previous caesarean in epidural analgesia a boy was born. Placenta was delivered spontaneously and perineal rupure sutured properly. About an hour after the delivery heavy pain was noted in the lower abdomen. Pelvic exam revealed a paravaginal haematoma and ultrasound scan coagulated and fresh blood behind the uterus. Rupture of the uterus was suspected and laparotomy revision performed. During the laparotomy there was no haemorrhage in the pelvic cavity, no uterine rupture but a large retroperitoneal haematoma extending to mesosigmoidal part of intestinum. Paravaginal heamatoma was evacuated vaginally and after half an hour the retroperitoneal haematoma diminished by 50 %. The patient received two blood transfusions. The blood loss was estimated as about 500 grams. The pulse and blood pressure were normal all the time. The laboratory values of haemoglobin was 96 g/l, haematocrit 0.30 before the operation and 93 g/l and 0.28 respectively 6 hours after. Beside anaemia the postoperative course was uneventful and the patient was dismissed from the hospital the 6th day postpartum. Conclusions. Although the laparotomy seems an excessive treatment it was the only way to exclude uterus rupture after a previous caesarean, heavy pain in the lower abdomen and blood behind the uterus noted on the ultrasound scan. In the non-urgent situation a CT scan could be performed to locate the blood accumulation and possibly exclude uterine rupture.

A 70-year-old man was diagnosed with retroperitoneal fibrosis (RPF) complicated by ureteral obstruction 4 months after finishing radiotherapy for prostate cancer. He was treated conservatively with ureteral stent placement. After 3 months, computed tomography scan of the abdomen revealed resolution of RPF without any medical or surgical interventions. Although an uncommon event, the possibility of spontaneous resolution of RPF, as demonstrated by this and previously reported cases, has led some to encourage conservative management.

Secondary poisoning of owls by anticoagulant rodenticides

Anticoagulants-compounds that prevent clotting of the blood-are extensively used for control of small mammal pests. The potential secondary hazards of 6 anticoagulant rodenticides to birds of prey were examined in this study. Whole rats or mice were killed with each anticoagulant and were fed to 1-3 species of owls. Owls died of hemorrhaging after feeding on rats killed with bromadiolone, brodifacoum, or diphacinone; sublethal hemorrhaging occurred in owls fed rats killed with difenacoum. These results demonstrate potential secondary hazards of 4 anticoagulants to avian predators. No abnormalities were observed in owls fed rats killed with fumarin and chlorophacinone

1995-01-01

Purpose: Local failure is frequent after conventional therapy for patients with retroperitoneal sarcomas. A Phase I/II multimodality approach was used, combining iododeoxyuridine (IdUrd) and radiation therapy, followed by attempted surgical resection, with the goal of improving local control. Methods and Materials: Patients with retroperitoneal sarcomas were treated with three to five consecutive cycles of treatment. Each 14-day cycle consisted of a continuous intravenous infusion of IdUrd on days 1-5, twice a day radiation therapy (1.25 Gy/fraction) on days 8-12, and a break on day 13 and 14. Surgical resection was attempted after three or five cycles. Patients resected after three cycles received an additional two cycles of treatment with radiation directed to the tumor bed. IdUrd dose was escalated in Phase I fashion (1000 mg/m 2 /day, 1333 mg/m 2 /day, and 1600 mg/m 2 /day). The median potential follow-up was 31 months. Results: Sixteen patients (13 with high grade tumors) were treated. The median maximum tumor size was 17 cm. Resection margins were negative in four patients, microscopically positive in four patients, and grossly positive in three patients. Five patients were not resected. The only grade 4 acute toxicity observed was vomiting which occurred in three patients receiving upper abdominal radiation. Postsurgical and long-term complications were rare. Median survival overall and for resected patients were 18 and 32 months, respectively. Local control was observed in three out of four patients with negative margins (9, 40+, and 51+ months), two out of four patients with microscopically positive margins (4 and 22 months), and one out of three patients with grossly positive margins (46+ months). The overall freedom from local progression was 45% at 24 months. Conclusion: Retroperitoneal sarcomas can be resected after preoperative radiation therapy and IdUrd, with encouraging local control in patients resected with negative or microscopically positive

To perform a bicenter, retrospective study of perioperative outcomes of retroperitoneal versus transperitoneal robotic-assisted laparoscopic partial nephrectomy (RALPN) and assess costs using time-driven activity-based costing (TDABC). We identified 355 consecutive patients who underwent RALPN at University of California Los Angeles and the University of Michigan during 2009-2016. We matched according to RENAL nephrometry score, date, and institution for 78 retroperitoneal versus 78 transperitoneal RALPN. Unadjusted analyses were performed using McNemar's Chi-squared or paired t test, and adjusted analyses were performed using multivariable repeated measures regression analysis. From multivariable models, predicted probabilities were derived according to approach. Cost analysis was performed using TDABC. Patients treated with retroperitoneal versus transperitoneal RALPN were similar in age (P = 0.490), sex (P = 0.715), BMI (P = 0.273), and comorbidity (P = 0.393). Most tumors were posterior or lateral in both the retroperitoneal (92.3%) and transperitoneal (85.9%) groups. Retroperitoneal RALPN was associated with shorter operative times (167.0 versus 191.1 min, P = 0.001) and length of stay (LOS) (1.8 versus 2.7 days, P factoring in disposable equipment, operative time, LOS, and personnel. In two high-volume, tertiary centers, retroperitoneal RALPN is associated with reduced operative times and shortened LOS in posterior and lateral tumors, whereas sharing similar clinicopathologic outcomes, which may translate into lower healthcare costs. Further investigation into anterior tumors is needed.

This personal series of 44 primary retroperitoneal masses (P.R.P.M.) studied by C.T. is analyzed. The reliability of C.T. in the identification (44/44), characterization (43/44) and origin evaluation (41/44) of P.R.P.M. has been absolutely satisfactory. In particular, those criteria of C.T. diagnosis which may be utilized in the evaluation of the origin of upper abdominal masses are thoroughly described. The evaluation of the involvement (non invasive; invasive) of adjacent viscera has been achieved in 22/38 P.R.P.M. verified at operation. The evaluation of tumour resectability has been less reliable due to the high incidence of under-diagnosis (60% in our personal experience). C.T. may be used in addition as an aid to different diagnostic techniques (percutaneous guided needle biopsy) or to therapy (drainage of retroperitoneal abscesses). C.T. is absolutely necessary in the follow-up of P.R.P.M. after surgery, radiotherapy or chemotherapy.

Staub, Blake N; Holman, Paul J

2015-02-01

The authors present the first reported use of the lateral retroperitoneal transpsoas approach for interbody arthrodesis in a patient with achondroplastic dwarfism. The inherent anatomical abnormalities of the spine present in achondroplastic dwarfism predispose these patients to an increased incidence of spinal deformity as well as neurogenic claudication and potential radicular symptoms. The risks associated with prolonged general anesthesia and intolerance of significant blood loss in these patients makes them ideal candidates for minimally invasive spinal surgery. The patient in this case was a 51-year-old man with achondroplastic dwarfism who had a history of progressive claudication and radicular pain despite previous extensive lumbar laminectomies. The lateral retroperitoneal transpsoas approach was used for placement of interbody cages at L1/2, L2/3, L3/4, and L4/5, followed by posterior decompression and pedicle screw instrumentation. The patient tolerated the procedure well with no complications. Postoperatively his claudicatory and radicular symptoms resolved and a CT scan revealed solid arthrodesis with no periimplant lucencies.

Full Text Available La trombolisis se usa como estrategia de reperfusión coronaria en el infarto agudo de miocardio. El sangrado es su principal complicación; la mayoría ocurre en los sitios de accesos venosos y es leve, pero también pueden presentarse hemorragia gastrointestinal, retroperitoneal, genitourinaria, pulmonar y a nivel del sistema nervioso central, episodios estos generalmente de mayor gravedad y a veces fatales. Se describe aquí el caso de un paciente que recibió terapia trombolítica con estreptoquinasa como tratamiento por un infarto de miocardio, y que posteriormente desarrolló insuficiencia respiratoria aguda, infiltrados pulmonares bilaterales, caída del hematocrito y aumento de la difusión de monóxido de carbono, cuadro compatible con diagnóstico de hemorragia alveolar.Coronary thrombolysis is used as a strategy for coronary reperfusion for acute myocardial infarction. Bleeding is the main complication described. Although most of these events occur at sites of vascular access and are mild, in some cases gastrointestinal, retroperitoneal, genitourinary, lung and central nervous system bleeding may occur. These episodes are usually serious and sometimes fatal. The following report describes the case of a patient who received thrombolytic therapy with streptokinase as a treatment for myocardial infarction. Subsequently he developed acute respiratory failure, bilateral pulmonary infiltrates and fall of hematocrit compatible with diagnosis of alveolar hemorrhage.

2003-01-01

Purpose: To describe de imaging features of this unusual localization of Castleman's disease. Materials and methods: Two patients (man: 62 years old, woman: 27 years old) with epigastric abdominal pain were studied. The physical examination was negative in the woman while in the other case a peri umbilical tumor was observed. The laboratory and the tumor markers were negative. Both patients had a history of appendectomy. US, TC and MRI were performed. After surgery the pathological examination included stain techniques with hematoxylin-eosin, Masson's techniques and PAS. Results: Retroperitoneal Castleman's disease in peri pancreatic localization (extremely rare). The US showed slight hypoechoic homogeneous lesions with clear rims. CT without contrast revealed isodense lesions and one of them presented a small calcification, the e.v. contrast CT showed a clear homogeneous reinforcement. MRI demonstrated hypointense lesions on T1, hyperintense on T2, and after the administration of gadolinium these lesions showed a marked reinforcement on the arterial phase, which persisted on the late venous phase. The differential diagnosis with pancreatic tumoral pathology was difficult. The pathological examination revealed a lymphoid angio follicular hyperplasia of hyaline vascular type. Conclusion: Retroperitoneal Castlelman's disease is a rare entity. The different imaging methods did not provide an accurate diagnosis of this entity since there are no pathognomonic features. The pathological examination was required to define the diagnosis in both reported cases. (author)

Nagar, Sapna

2012-02-01

Ectopic liver tissue is a rare clinical entity that is mostly asymptomatic and found incidentally. In certain situations, however, patients may present with symptoms of abdominal pain secondary to torsion, compression, obstruction of adjacent organs, or rupture secondary to malignant transformation. Herein, we report a case of a 25-year-old female that presented with acute onset of epigastric pain found to have ectopic liver tissue near the gallbladder complicated by acute hemorrhage necessitating operative intervention in the way of laparoscopic excision and cholecystectomy. The patient\\'s postoperative course was uneventful. Gross pathology demonstrated a 1.2 x 2.8 x 4.5 cm firm purple ovoid structure that histologically revealed extensive hemorrhagic necrosis of benign ectopic liver tissue.

2012-01-01

Purpose: This study was designed to determine the feasibility and efficacy of endovascular embolization with liquid embolic agent ethylene vinyl alcohol copolymer (Onyx) in patients with acute traumatic arterial bleeding. Methods: This is a retrospective review of 13 patients (9 men and 4 women; mean age 45 years) with severe trauma who underwent embolotherapy using Onyx from November 2003 to February 2009. Bleeding was located in the pelvis (5 patients), kidney (3 patients), mesenteric region (2 patients), retroperitoneal space (2 patients), neck (1 patient), and thigh (1 patient). In three cases (23.1%), Onyx was used in conjunction with coils. We evaluate the technical and clinical success, procedural and embolization time, occurrence of rebleeding, and embolotherapy-related complications, such as necrosis or migration of Onyx into nontarget vessels. Results: In all patients, embolotherapy was technically and clinically successful on the first attempt. Control of bleeding could be reached with a mean time of 19 (range, 4–63) min after correct placement of the microcatheter in the feeding artery. No recurrent bleeding was detected. No unintended necrosis or migration of Onyx into a nontarget region was observed. During the follow-up period, three patients (23.1%) died due to severe intracranial hemorrhage, cardiac arrest, and sepsis. Conclusions: Transcatheter embolization with new liquid embolic agent Onyx is technically feasible and effective in trauma patients with acute arterial hemorrhage.

To observe the pattern and mortality of Congo-Crimean Hemorrhagic Fever (CCHF) in Balochistan. Two hundred and twenty-six febrile patients with bleeding of sudden onset, with initial signs and symptoms including headache, high fever, back pain, joint pain, stomach pain, vomiting, red eyes, flushed face, red throat and petechiae on the palate of both sexes were screened for CCHF over a period of 10 years. Clinical criteria for initial diagnosis directed the subsequent diagnostic work-up. The ages of these patients ranged from 7 years to 74 years. Sixty-three percent of these patients were positive for CCHF. Males were 68% of the total patients. Over the years, CCHF showed a gradual increase ranging from 43% to 80%. Total mortality was 15%, all being secondary cases. Death was not observed in primary CCHF cases. In this study, suspicion of viral hemorrhagic fever was raised in 62% cases at the time of admission and the patients were immediately isolated, noninvasive procedures were instigated and barrier nursing was implemented. None of the family and hospital staff members who had close contact with the patient became ill, while those who were not suspected initially (38%) infected the health care workers and the family members. Although CCHF is rare, this study stresses the need for proper health facilities in Pakistan and to include VHF (viral hemorrhagic fevers) in the differential diagnosis of unexplained fever with hemorrhagic tendencies of sudden onset.

Data are lacking on the risk and impact of a serious hemorrhage on the prognosis after ischemic stroke (IS) or transient ischemic attack (TIA). We aimed to estimate the incidence of serious hemorrhage, analyze the impact on mortality, and identify predictors of hemorrhage after discharge from IS or TIA. All patients admitted to Östersund Hospital for an IS or TIA in 2010-2013 were included (n = 1528, mean age: 75.1 years). Serious hemorrhages were identified until 31st December 2015. Incidence rates were calculated. The impact on mortality (stratified by functional level) was determined with Kaplan-Meier analysis. Non-parametric estimation under the assumption of competing risk was performed to assess the cumulative incidence and predictors of serious hemorrhages. The incidence rates of serious (n = 113) and intracranial hemorrhages (n = 45) after discharge from IS and TIA were 2.48% and 0.96% per year at risk, respectively. Patients with modified Rankin Scale (mRS) scores of 3-5 exhibited 58.9% mortality during follow-up and those with mRS scores of 0-2 exhibited 18.4% mortality. A serious hemorrhage did not affect mortality in patients with impaired functional status, but it increased the risk of death in patients with mRS scores of 0-2. Hypertension was associated with increased risk of serious hemorrhage. We found that, after discharge from an IS or TIA, serious hemorrhages were fairly common. Impairments in function were associated with high mortality, but serious hemorrhages only increased the risk of mortality in patients with no or slight disability. Improved hypertension treatment may decrease the risk of serious hemorrhage, but in patients with low functional status, poor survival makes secondary prevention challenging.

Localized bilateral perirenal fibrosis, a rare cause of idiopathic retroperitoneal fibrosis

Full Text Available Background: Idiopathic retroperitoneal fibrosis is an infrequent process of unknown aetiology characterised by fibrous tissue proliferation in the retroperitoneum. Even less frequent is a localized form of this disease by a proliferation of fibrous tissue around single or both kidneys.Case report: We describe a case of 46-year old man in whom medical management was started for accidentally discovered arterial hypertension, which turned out to be difficult to control.   During diagnostic work-up of hypertension, an abdominal ultrasound was obtained a year later demonstrating slight bilateral caliectasis without obvious visible cause for it. Laboratory exams have shown significantly impaired renal function, normocytic anaemia, slightly higher sedimentation rate, increased CRP and normal urinalysis. Nephrologist has decided for hospitalisation during which magnetic resonance imaging was performed  showing a few mm wide tissue coats surrounding both kidneys with fluid lying between the coat and kidney capsule. A biopsy of perirenal mass has confirmed a dense cellular lesion consisted of interweaved fascicles of spindle-shaped cells. After exclusion of tumours and other causes, a diagnosis of retroperitoneal fibrosis was confirmed. Clinical picture and laboratory data corresponded to idiopathic form of this disease. A treatment with tamoxifen was started after patient refused treatment with methylprednisolone. During tamoxifen monotherapy, there was gradual significant improvement of general symptoms, notable decline in inflammation markers, improvement of anaemia, normalisation of kidney function, and normalisation of blood pressure. Conclusion: Retroperitoneal fibrosis is still an obscure and multifaceted disease. A proper selection of diagnostic methods is the key to correct and fast diagnosis as well as good grounding for proper treatment.

Primary retroperitoneal mucinous cystadenoma (PRMC) is an extremely rare tumor: its histogenesis and its biological behavior remain speculative. Since most retroperitoneal tumors are malignant, a preoperative diagnosis of benignity is essential and it can be reached through imaging examinations, allowing a conservative management approach. We describe the case of a 52-year-old woman with abdominal pain and a palpable mass. Computed tomography of the abdomen revealed a retroperitoneal cystic mass, which was resected successfully through laparoscopy and diagnosed as PRMC. Although there are no pathognomonic, clinical or radiological findings for PRMC, it should be included in the list of differential diagnoses and its imaging criteria of benignity should always be sought, with the aim to exclude malignant tumors.

A convolutional neural network for intracranial hemorrhage detection in non-contrast CT

The assessment of the presence of intracranial hemorrhage is a crucial step in the work-up of patients requiring emergency care. Fast and accurate detection of intracranial hemorrhage can aid treating physicians by not only expediting and guiding diagnosis, but also supporting choices for secondary imaging, treatment and intervention. However, the automatic detection of intracranial hemorrhage is complicated by the variation in appearance on non-contrast CT images as a result of differences in etiology and location. We propose a method using a convolutional neural network (CNN) for the automatic detection of intracranial hemorrhage. The method is trained on a dataset comprised of cerebral CT studies for which the presence of hemorrhage has been labeled for each axial slice. A separate test dataset of 20 images is used for quantitative evaluation and shows a sensitivity of 0.87, specificity of 0.97 and accuracy of 0.95. The average processing time for a single three-dimensional (3D) CT volume was 2.7 seconds. The proposed method is capable of fast and automated detection of intracranial hemorrhages in non-contrast CT without being limited to a specific subtype of pathology.

Neonatal adrenal hemorrhage is uncommon. It is present in 0,2% of newborns. Ten percent of the cases occur bilaterally. It can be associated with birth trauma, large birth weight, or neonatal course complicated by hypoxia and asphyxia, hypotension, or coagulopathy. Scrotal hematoma is an extremely rare manifestation of NAH. Most patients present scrotal swelling with bluish discolouration. Scrotal swelling with/without bluish discoloration in newborns may result from different causes. We report an unusual case of neonatal adrenal hemorrhage secondary to perinatal asphyxia, associated with SH. Neonatal adrenal hemorrhage and scrotal hematoma were diagnosed by ultrasonography and treated by conservative treatment, avoiding unnecessary surgical exploration.

Retroperitoneal Cellular Angiofibroma: A Rare Gynecological Entity

Ana Brandão

2017-12-01

Full Text Available Cellular angiofibroma is a mesenchymal tumor, described in 1997, without gender preference, that usually appears at age 40. The vulvovaginal area is the most common site in women, mimicking vulvar benign tumors, like Bartholin gland cyst. However, there are a few described cases of a deep or extra-pelvic angiofibroma. Excision is the treatment of choice and the recurrence rate appears to be low. We present the case of a woman with a heterogeneous tumor in the right adnexial region. At the surgery, a retroperitoneal tumor was excised and the histopathological tissue analysis revealed a cellular angiofibroma.

Rationale Acute intracerebral hemorrhage inflicts a high-economic and -health burden. Computed tomography angiography spot sign is a predictor of hematoma expansion, is associated with poor clinical outcome and is an important stratifying variable for patients treated with haemostatic therapy. Aims We aim to compare the effect of treatment with tranexamic acid to placebo for the prevention of hemorrhage growth in patients with high-risk acute intracerebral hemorrhage with a positive spot sign. Design The tranexamic acid for acute intracerebral hemorrhage growth predicted by spot sign (TRAIGE) is a prospective, multicenter, placebo-controlled, double-blind, investigator-led, randomized clinical trial that will include an estimated 240 participants. Patients with intracerebral hemorrhage demonstrating symptom onset within 8 h and with the spot sign as a biomarker for ongoing hemorrhage, and no contraindications for antifibrinolytic therapy, will be enrolled to receive either tranexamic acid or placebo. The primary outcome measure is the presence of hemorrhage growth defined as an increase in intracerebral hemorrhage volume >33% or >6 ml from baseline to 24 ± 2 h. The secondary outcomes include safety and clinical outcomes. Conclusion The TRAIGE trial evaluates the efficacy of haemostatic therapy with tranexamic acid in the prevention of hemorrhage growth among high-risk patients with acute intracerebral hemorrhage.

Full Text Available Two unlike metals near one another can break down as they move toward electrochemical equilibrium resulting in galvanic corrosion. We describe a case of electrochemical corrosion resulting in pseudarthrosis, followed by instrumentation failure leading to subarachnoid hemorrhage. A 53-year-old female with a history of cervical instability and two separate prior cervical fusion surgery with sublaminar cables presented with new onset severe neck pain. Restricted range of motion in her neck and bilateral Hoffman's was noted. X-ray of her cervical spine was negative. A noncontrast CT scan of her head and neck showed subarachnoid hemorrhage in the prepontine and cervicomedullary cisterns. Neurosurgical intervention involved removal of prior stainless steel and titanium cables, repair of cerebrospinal fluid leak, and nonsegmental C1–C3 instrumented fusion. She tolerated the surgery well and followed up without complication. Galvanic corrosion of the Brook's fusion secondary to current flow between dissimilar metal alloys resulted in catastrophic instrumentation failure and subarachnoid hemorrhage.

Hemorrhagic pleural effusion secondary to an unusual type III hiatal hernia in a 4-year-old great dane.

2010-01-01

An unusual case of combined axial and paraesophageal (type III) hiatal hernia (HH) in a 4-year-old Great Dane is reported. The main presenting complaint was dyspnea, and no history of trauma was present. A tentative diagnosis of HH with secondary pleural effusion was made based on clinical signs and radiographic findings. Exploratory celiotomy revealed herniation of the gastric cardia, fundus, and body through the esophageal hiatus and an adjacent, distinct defect in the diaphragm. Rupture of the short gastric vessels lead to the formation of a hemorrhagic pleural effusion that impaired ventilation. The esophageal hiatus was surgically reduced in size, and the second defect was closed with nonabsorbable sutures. Esophagopexy and tube gastropexy procedures were also performed. The dog was clinically normal 9 months postoperatively. This type of HH is not currently defined within the traditional classification system and to the authors' knowledge has not been previously reported.

Singal, Rikki; Dhar, Siddharth

2018-01-01

The introduction of endourological procedures such as percutaneous nephrolithotomy and ureterorenoscopy have led to a revolution in the the management of urinary stone disease. The indications for open stone surgery have been narrowed significantly, making it a second- or third-line treatment option. To study the safety and efficacy of retroperitoneal laparoscopic pyelolithotomy in retroperitoneal renal stone. We compared the results of laparoscopic and open surgery in terms of easy accessibility, operative period, renal injuries, and early recovery. This prospective study was conducted on renal pelvic stone cases from January 2009 to February 2016 in Suchkhand Hospital, Agra, India. The study included a total of 1700 cases with the diagnosis of solitary renal pelvic stones. In group A - 850 cases - retroperitoneal laparoscopic pyelolithotomy was performed, while group B - 850 cases - underwent open pyelolithotomy. The mean operative time was less in group B than group A (74.83 min vs. 94.43 min) which was significant (p<0.001). The blood loss was less in the laparoscopic group than in the open group (63 mL vs. 103mL). There were statistically significant differences in the post-operative pain scores, and postoperative complications compared to group B (p<0.001). The mean hospital stay was less in group A (p<0.03), which was significant. Laparoscopic surgery reduces analgesic requirements, hospital stay, and blood loss. The disadvantages include the reduced working space, the cost of equipment and the availability of a trained surgeon.

To the best of our knowledge, the formation of a retroperitoneal abscess due to acute appendicitis shortly after administration of chemotherapy for lung cancer has not been previously reported. This is the case report of a 59-year-old male who was admitted to the Mito Medical Center (Mito, Japan) and diagnosed with lung adenocarcinoma with pleuritis carcinomatosis. Although no distant metastasis was identified, combination chemotherapy with cisplatin and pemetrexed was administered. Nine days after initiating chemotherapy, the patient developed right lower quadrant abdominal pain and high fever. Computed tomography (CT) of the abdomen and pelvis revealed the collection of gas and fluid in the retroperitoneum adjacent to the cecum. The abscess was locally drained; however, the infection continued to spread, with subsequent development of a scrotal abscess. Consequently, appendectomy was performed. The patient recovered well and the lung adenocarcinoma was treated with additional courses of chemotherapy following the remission of the local inflammation. Retroperitoneal abscess due to acute appendicitis is an unusual finding; however, this rare complication should be considered during or shortly after chemotherapy in patients with lung cancer.

Four cases of primary and secondary malignant hemangiopericytoma were correlatively studied using selective angiography, computed tomography, and pathologic specimens. One case was found in each of the peritoneal space (metastasis), the left middle cranial fossa, the left thigh, and the left retroperitoneal space. Basic angiographic features of the tumor were a few feeding arteries entering the tumor with radially arranged fine network throughout, early visualization of veins due to A-V shunting, and a long-standing tumor stain with avascular area (s). Correlative evaluation of angiograms, computed tomograms, and pathologic specimens revealed hemorrhage, central necrosis, and cystic degeneration for the avascular area (s) of the tumor stains on the angiograms. The more prominent those secondary changes, the less characteristic the angiographic features.

1990-01-01

Many cephalosporin antibiotics have recently been invented and attempts have been made to use them clinically. The choice of which of these drugs should be used has been difficult in gynecology. The efficacies of these drugs depend on their antibacterial spectra, potencies, and concentrations in tissues. This study was designed to investigate the pharmacokinetics of various cephem antibiotics in the exudate of the retroperitoneal space that is formed after radical hysterectomy and pelvic lymphadenectomy. These cephem antibiotics were cefoxitin, cefotiam, cefotetan, cefpiramide, cefminox, cefotaxime, ceftizoxime, cefoperazone, cefmenoxime, cefbuperazone, ceftazidime, cefpimizole, flomoxef, and cefuzonam. The maximum concentrations after administration of a 1-g dose in the exudate of the pelvic retroperitoneal space were 37.9 micrograms/ml with cefminox, 30.3 micrograms/ml with cefpimizole, 21.6 micrograms/ml with flomoxef, 21.5 micrograms/ml with ceftazidime, and 17.6 micrograms/ml with cefbuperazone, which were relatively high. When selecting antibiotics for prophylactic use against infections in the retroperitoneal space after radical hysterectomy and pelvic lymphadenectomy, on the basis of drug transfer, flomoxef, cefminox, cefbuperazone, ceftazidime, and cefpimizole were considered to be the drugs of first choice at a dose of 1 g.

A cutting biopsy needle for the histological diagnosis of abdominal and retroperitoneal masses

International Nuclear Information System (INIS)

Hauenstein, K.H.; Wimmer, B.; Freudenberg, N.; Freiburg Univ.

1985-01-01

A new cutting biopsy needle has been used to obtain histologically useful material while causing the minimum of trauma. It permits biopsies of organs, but its small external diameter of 0.8 or 0.95 mm makes it possible to carry out transperitoneal puncture of the stomach, colon or liver and of the retroperitoneal space, using a ventral approach. Tissue samples were obtained in 96% of 63 patients. The risk of complications is no higher than for conventional needles used for cytology. The accuracy with which the material can be obtained is therefore the most important problem. The position of the area to be biopsied should determine whether the biopsy is to be aided by sonography or CT. Biopsies of organs can be appropriately carried out under ultrasound control, but processes in the pelvis and in retroperitoneal-paravertebral and extra-peritoneal positions are best biopsied under CT control.

Subpial Hematoma and Extravasation in the Interhemispheric Fissure with Subarachnoid Hemorrhage

Science.gov (United States)

Matsuoka, Go; Abe, Kayoko; Okada, Yoshikazu; Sakai, Shuji

2015-01-01

A recent report on computed tomography (CT) findings of contrast extravasation in subarachnoid hemorrhage (SAH) with Sylvian hematoma suggests that the occurrence of the hematoma is secondary to bleeding in the subpial space. Our patient was in his sixties and was admitted to the hospital because of loss of consciousness (Glasgow Coma Scale E4V1M4). SAH was diagnosed in plain head CT, and growing hematomas were observed in the Sylvian and interhemispheric fissures following a subarachnoid hemorrhage. CT angiography (CTA) using a dual-phase scan protocol revealed contrast extravasation in both the fissures in the latter phase, and hematoma in the interhemispheric fissure contained multiple bleeding points. This case indicates that the occurrence of subpial hematoma such as Sylvian hematoma can be a secondary event following subpial bleeding from damaged small vessels elsewhere in the cranium. Instead of four-dimensional (4D) CT, the dual-phase CTA technique may help detect minor extravasations with usual helical CT scanner. PMID:25963159

Nattokinase is used as a health-promoting medicine for preventing thrombosis due to its fibrinolytic activity. Cerebral microbleed is remnant of blood extravasations from the damaged vessels related to cerebral microangiopathies. We report a patient, having used aspirin for secondary stroke prevention, who had an acute cerebellar hemorrhage after taking nattokinase 400 mg daily for 7 consecutive days. In addition to the hemorrhagic lesion, multiple microbleeds were demonstrated on brain MR images. We suggest that nattokinase may increase risk of intracerebral hemorrhage in patients who have bleeding-prone cerebral microangiopathy and are receiving other antithrombotic agent at the same time.

Full Text Available "nGerminal matrix-intraventricular hemorrhage (IVH is the most common variety of neonatal intracranial hemorrhage and is characteristics of the premature infant. The importance of the lesion relates not only to its high incidence but to their attendant complications (IC: hydrocephalus. Brain sonography is the procedure of choice in diagnosis of germinal matrix- intraventricular hemorrhage and hydrocephalus. In this study we have used brain sonography for detection of intraventricular hemorrhage and post hemorrhagic hydrocephalus and their incidences. The studied population was consisted of premature neonate (birth weight equal or less than 1500g and gestational age equal or less than 37 weeks who admitted in Mofid Hospital NICU (Tehran, Iran during a one year period. For all neonate (including criteria brain sonography in first week of life was done and in presence of IVH, serial Brain sonography was done weekly for detection of hydrocephalus. A total of 57 neonate entered the study. Intraventicular-germinal matrix hemorrhage was seen in 64.4% (35 patients. Forty percent of patients with intraventricular-germinal matrix hemorrhage had grade I, 11% grade II, 25.7% grade III, 2.8% grade VI. Hydrocephalus was detected in 20 percent of patients who had intraventricular-germinal matrix hemorrhage. That incidence of IVH in our study in comparison with other area and situation is higher. Hydrocephaly had direct relation with severity of IVH. This shows that with control of risk factor of IVH, we can control Post hemorrhagic hydrocephalus.

The symptoms of hypertensive putaminal hemorrhage and of middle cerebral artery occlusion are sometimes similar to each other. Hemorrhage sometimes occurs following cerebral infarction. We experienced 7 patients with hemorrhages localized in the basal ganglia following cerebral infarction. The CT findings of 55 patients with putaminal hemorrhage and 7 patients with hemorrhagic infarction localized at the basal ganglia were investigated retrospectively in order to discuss their characteristics. The high-density area (HD) of a putaminal hemorrhage was homogeneous on a plain CT within a week of the onset. There was a close correlation between the size of the HD and the timing of its disappearance. The HD with a maximum diameter of A cm generally disappeared A weeks after. On the other hand, the HD of a hemorrhagic infarction was lower in density than that of the putaminal hemorrhage. The HD of a hemorrhagic infarction generally disappeared earlier than that of a putaminal hemorrhage. Ring enhancement was visualized on contrast-enhanced CT (CECT) from 2 or 3 weeks after the onset in patients with putaminal hemorrhages except in the case of small hemorrhages (less than 1 cm diameter). Ring enhancement was also visualized in 6 out of 7 patients with hemorrhagic infarction; one of them was recognized within a week of the onset. Contrast enhancement of the cortex in the territory of the middle cerebral artery was visualized in 4 out of 7 patients with hemorrhagic infarction. This finding seems to indicate one characteristic of hemorrhagic infarction. (author)

Objective To determine the prognostic significance of histologic type/subtype in a large series of patients with primary resected retroperitoneal sarcoma. Summary Background Data The histologic diversity and rarity of retroperitoneal sarcoma has hampered the ability to predict patient outcome. Methods From a single-institution, prospective database, 675 patients treated surgically for primary, non-metastatic retroperitoneal sarcoma during 1982–2010 were identified and histologic type/subtype was reviewed. Clinicopathologic variables were analyzed for association with disease-specific death (DSD), local recurrence (LR), and distant recurrence (DR). Results Median follow-up for survivors was 7.5 years. The predominant histologies were well-differentiated liposarcoma, dedifferentiated liposarcoma, and leiomyosarcoma. Five-year cumulative incidence of DSD was 31%, and factors independently associated with DSD were R2 resection, resection of ≥3 contiguous organs, and histologic type. Five-year cumulative incidence for LR was 39% and for DR was 24%. R1 resection, age, tumor size, and histologic type were independently associated with LR; size, resection of ≥3 organs, and histologic type were independently associated with DR. Liposarcoma and leiomyosarcoma were associated with late recurrence and DSD (as long as 15 years from diagnosis). For solitary fibrous tumor, local recurrence was uncommon (sarcoma. Histology predicts the pattern and incidence of LR and DR and will aid in more accurate patient counseling and selection of patients for adjuvant therapy trials. PMID:25915910

Intracranial Hemorrhage

Science.gov (United States)

2011-01-01

Intracranial hemorrhage is a life-threatening condition, the outcome of which can be improved by intensive care. Intracranial hemorrhage may be spontaneous, precipitated by an underlying vascular malformation, induced by trauma, or related to therapeutic anticoagulation. The goals of critical care are to assess the proximate cause, minimize the risks of hemorrhage expansion through blood pressure control and correction of coagulopathy, and obliterate vascular lesions with a high risk of acute rebleeding. Simple bedside scales and interpretation of computed tomography scans assess the severity of neurological injury. Myocardial stunning and pulmonary edema related to neurological injury should be anticipated, and can usually be managed. Fever (often not from infection) is common and can be effectively treated, although therapeutic cooling has not been shown to improve outcomes after intracranial hemorrhage. Most functional and cognitive recovery takes place weeks to months after discharge; expected levels of functional independence (no disability, disability but independence with a device, dependence) may guide conversations with patient representatives. Goals of care impact mortality, with do-not-resuscitate status increasing the predicted mortality for any level of severity of intraparenchymal hemorrhage. Future directions include refining the use of bedside neuromonitoring (electroencephalogram, invasive monitors), novel approaches to reduce intracranial hemorrhage expansion, minimizing vasospasm, and refining the assessment of quality of life to guide rehabilitation and therapy.

Full Text Available We report an extremely rare and unusual case of retroperitoneal and pelvic metastasis from primary squamous cell carcinoma of vallecula. Generally carcinoma oropharynx metastasizes to lungs, liver and bone while retroperitoneal and pelvic metastasis is rarely heard of. To the best of our knowledge this case is one of the scantly reported cases ever of this kind in the world.  A 60-year-old male presented with dysphagia and hoarseness of voice of four month duration.  Computed tomography (CT scan face and neck showed growth right vallecula. Biopsy of lesion showed squamous cell carcinoma. Metastatic work up was negative. He received definitive chemo-radiation. Patient during follow up presented with dyspepsia, abdominal discomfort and weight loss. Whole body positron emission tomography (WB PET scan revealed retroperitoneal and pelvic lymph node deposits which were confirmed as metastasis of squamous cell carcinoma by CT guided fine needle aspiration cytology (FNAC. Patient was exhibited palliative chemotherapy but his general condition deteriorated and he finally succumbed to his metastatic illness. This case is being reported to highlight its extreme rarity, the diagnostic and therapeutic challenges it presented and its overall dismal prognosis.

Intracerebral hemorrhage (ICH) accounts for ∼ 10 to 15% of all strokes and is one of the major causes of stroke-related death and disability. After the initial hemorrhage, further bleeding and edema contribute to secondary damage and worsened outcomes. As such, goals of previous and ongoing trials are to prevent continued bleeding, as well as mitigate the impact of cerebral edema. Although no trials have shown a definite functional outcome benefit with a given intervention, much progress has been made recently. This review focuses on recent developments that inform the acute management of ICH. Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.

Objective: To evaluate the early response rate and radiation toxicity of CyberKnife in the treatment of primary or metastatic retroperitoneal tumors. Methods: Twenty-eight patients with retroperitoneal tumors were treated with CyberKnife. The total doses were 2000-6000 cGy (median 4500 cGy) and biological effective doses were 3750-10080 cGy (median 7680 cGy) in 2-10 fractions (median 5). Of all patients, 3 received three dimensional conformal radiotherapy (3DCRT) or intensity modulated radiotherapy (IMRT) boost, 1 was treated as second-course radiotherapy, and others were treated with CyberKnife only. The survival rates were calculated by Kaplan-Meier method and compared with Logrank test. Results: The complete response, stable disease and progression disease rates were 43% (12/28), 6% (10/28), 18% (5/28), 4%, (1/28), respectively. The overall response rate was 96%. The number of patients who were followed up more than 1, 2, 3 years were 17, 9, 7, respectively. The 1-, 2- and 3-year local control rates were 92%, 86%, and 86%, respectively. The 1-, 2- and 3-year overall survival rates were 60%, 49% and 49%, respectively. The difference between local progression-free survival and overall survival was not significant (median 9.5 and 12.0 months, χ 2 =0.17, P=0.680), Moreover, if the patients did not have metastasis elsewhere and local treatment was effective, there was no significant difference between local progression-free survival and progression free survival (median 17 and 11 months, χ 2 =0.13, P=0.720), Acute radiation-induced side effects (≥ 2 grade) such as fatigue, anorexia, nausea, vomiting and epigastric discomfort occurred in 9, 9, 7, 7 and 2 patients, respectively. Intestinal stenosis of 1 grade occurred in 1 patients. Conclusions: Radiotherapy for retroperitoneal tumors with CyberKnife has provided a high response rate with minimal side effects. It is a safe and effective local treatment method for retroperitoneal tumors. (authors)

Objective: To explore the causes and preventive measures of symptomatic intracranial hemorrhage in 217 patients with acute cerebral ischemic stroke treated with local intra-arterial urokinase. Methods: From February 1999 to June 2004, 217 patients were treated for acute ischemic stroke with local intra-arterial urokinase in our hospital. Factors associated with symptomatic intracranial hemorrhage of intra-arterial thrombolysis were analyzed by Stepwise logistic regression to identify some factors relating the prediction symptomatic intracranial hemorrhage. Results: Symptomatic intracranial hemorrhage occurred in 8 cases (3.7%). Predictors of the symptomatic intracranial hemorrhage were the elevated systolic blood pressure before therapy (odds ratio, 1.096; 95% CI, 1.006 to 1.194) and urokinase (UK) treatment (odds ratio, 1.068 ; 95% CL, 1.053 to 1.247). Risk of secondary symptomatic intracranial hemorrhage was increased with elevated systolic blood pressure. Other factors like age, initial treating time, NIHSS, diabetes and collateral circulation did not predict the symptomatic intracranial hemorrhage respectively. Conclusions: Predictors of symptomatic intracranial hemorrhage after local intra-arterial infusion of urokinase for acute ischemic stroke were the elevated systolic blood pressure before therapy and urokinase (UK) treatment.

Spontaneous adrenal pheochromocytoma rupture complicated by intraperitoneal hemorrhage and shock

Full Text Available Abstract MEN2A is a hereditary syndrome characterized by medullary thyroid carcinoma, hyperparathyroidism, and pheochromocytoma. Classically patients with a pheochromocytoma initially present with the triad of paroxysmal headaches, palpitations, and diaphoresis accompanied by marked hypertension. However, although reported as a rare presentation, spontaneous hemorrhage within a pheochromocytoma can present as an abdominal catastrophe. Unrecognized, this transformation can rapidly result in death. We report the only documented case of a thirty eight year old gentleman with MEN2A who presented to a community hospital with hemorrhagic shock and peritonitis secondary to an unrecognized hemorrhagic pheochromocytoma. The clinical course is notable for an inability to localize the source of hemorrhage during an initial damage control laparotomy that stabilized the patient sufficiently to allow emergent transfer to our facility, re-exploration for continued hemorrhage and abdominal compartment syndrome, and ultimately angiographic embolization of the left adrenal artery for control of the bleeding. Following recovery from his critical illness and appropriate medical management for pheochromocytoma, he returned for interval bilateral adrenal gland resection, from which his recovery was unremarkable. Our review of the literature highlights the high mortality associated with the undertaking of an operative intervention in the face of an unrecognized functional pheochromocytoma. This reinforces the need for maintaining a high index of suspicion for pheochromocytoma in similar cases. Our case also demonstrates the need for a mutimodal treatment approach that will often be required in these cases.

1986-01-01

Tumor hemorrhage on computed tomography (CT) was found in 14 patients with brain metastases (7 % of two hundred patients with brain metastases), from April 1979 to July 1983. Primary foci of these lesions were the lung (6 patients), breast (2), kidney (2), uterus (2), colon (1) and adrenal gland (1). ''Stroke'' syndrome was the initial presenting symptom in 3 patients; neurological focal sign or symptoms of increased intracranial pressure in the remaining patients. CT demonstrated peritumoral hemorrhage in all patients with solid mass, intratumoral hemorrhage in a few patients and also cerebral or ventricular hemorrhage, which was fatal complication, in 2 patients (colon and breast cancers). A cystic mass with fluid-blood level was noted in a patient with breast cancer. Several predisposing factors including chemotherapy, thrombocytopenia, radiotherapy or combination of these were recognized in 8 patients. Of these, chemotherapy was the most causative factor of tumor hemorrhage. Brain irradiation for hemorrhagic brain metastases was effective for prolongation of mean survival time of these patients as follows; 10 months in irradiated group, whereas 1.5 months in non-irradiated group.

Nosaka, Yoshiki

1981-01-01

Thirteen patients exhibited a communicating hydrocephalus following subarachnoid hemorrhage secondary to ruptured intracranial aneurysms and were treated with shunt procedures. The interval between subarachnoid hemorrhage and surgery averaged 9 weeks. Seven of the patients showed improvement. The prognostic value for surgical management was evaluated on the basis of three different diagnostic examinations (computed tomography (CT), cisternography and constant infusion test). A correct diagnosis was obtained in 78 per cent in cisternography, and 63 per cent in infusion test and CT. All patients responding to surgery showed a typical pattern in cisternography, consisting of ventricular retention of radiopharmaceutical tracer for 48 h or longer in association with no radioactivity over the cerebral hemispheres. The constant infusion test correlated well with typical cisternographic patterns. CT is useful in demonstrating pathophysiological changes in hydrocephalus. Periventricular hypodensity was visible in patients with normal or slightly elevated intracranial pressure, accompanied by fairly rapid deterioration. All of them responded well to shunting. In most cases which benefited from the shunt, the postoperative CT showed not only normal-sized ventricles but also marked regression of the hypodensity over a short period. (author)

Background Natriuresis with polyuria is common after aneurysmal subarachnoid hemorrhage (aSAH). Previous studies have shown an increased risk of symptomatic cerebral vasospasm or delayed cerebral ischemia (DCI) in patients with hyponatremia and/or the cerebral salt wasting syndrome (CSW). However, natriuresis may occur in the absence of hyponatremia or hypovolemia and it is not known whether the increase in DCI in patients with CSW is secondary to a concomitant hypovolemia or because the phys...

Retroperitoneal uterine leiomyoma is a very rare occurrence and to discover it as a cause of female sexual dysfunction in a teen is unusual. An 18-year-old black woman reported deep dyspareunia, resulting in severe distress. Gynecological and instrumental examinations showed a pelvic mass of 7 cm in diameter. The preoperative diagnosis was uterine fibroid, but the exact location of the leiomyoma was uncertain. Laparoscopic examination showed a pedunculated retroperitoneal cervical leiomyoma in the left pararectal space. After surgical excision of the mass, normal sexual activity was restored. When a teen experiences pain with intercourse, pelvic masses should be part of differential diagnosis of dyspareunia. Copyright © 2016 North American Society for Pediatric and Adolescent Gynecology.

2014-01-01

We reported a case of spontaneous retroperitoneal hematoma (SRH) simulating a ruptured infrarenal aortic aneurysm. A 72-year-old man with a history of infrarenal aortic aneurysm and end-stage renal disease on hemodialysis presented with malaise and nonspecific central abdominal pain and left loin discomfort. An emergency computed tomography scan showed a large retroperitoneal hematoma and clinical suspicion of ruptured infrarenal aortic aneurysm. However, the hematoma was discontinuous with the aneurysm sac and raised the clinical suspicion on dual pathology. The SRH was treated conservatively with transfusion of blood products, and the aneurysm was treated with nonemergency endovascular repair electively. This case demonstrates the importance of recognizing different clinical and radiological characteristics and be aware of dual pathology. PMID:28031651

The increase in the risk for bleeding associated with antithrombotic therapy causes a dilemma in patients with atrial fibrillation (AF) who sustain an intracranial hemorrhage (ICH). A thrombotic risk is present; however, a risk for serious harm associated with resumption of anticoagulation therapy also exists. To investigate the prognosis associated with resuming warfarin treatment stratified by the type of ICH (hemorrhagic stroke or traumatic ICH). This nationwide observational cohort study included patients with AF who sustained an incident ICH event during warfarin treatment from January 1, 1998, through February 28, 2016. Follow-up was completed April 30, 2016. Resumption of warfarin treatment was evaluated after hospital discharge. No oral anticoagulant treatment or resumption of warfarin treatment, included as a time-dependent exposure. One-year observed event rates per 100 person-years were calculated, and treatment strategies were compared using time-dependent Cox proportional hazards regression models with adjustment for age, sex, length of hospital stay, comorbidities, and concomitant medication use. A total of 2415 patients with AF in this cohort (1481 men [61.3%] and 934 women [38.7%]; mean [SD] age, 77.1 years [9.1 years]) sustained an ICH event. Of these events, 1325 were attributable to hemorrhagic stroke and 1090 were secondary to trauma. During the first year, 305 patients with a hemorrhagic stroke (23.0%) died, whereas 210 in the traumatic ICH group (19.3%) died. Among patients with hemorrhagic stroke, resuming warfarin therapy was associated with a lower rate of ischemic stroke or systemic embolism (SE) (adjusted hazard ratio [AHR], 0.49; 95% CI, 0.24-1.02) and an increased rate of recurrent ICH (AHR, 1.31; 95% CI, 0.68-2.50) compared with not resuming warfarin therapy, but these differences did not reach statistical significance. For patients with traumatic ICH, resuming warfarin therapy also was associated with a lower rate of ischemic stroke

The clinical and CT findings in 10 patients with primary pontine hemorrhage were reviewed. All patients were hypertensive. Pontine hemorrhage can be divided into 3 groups from the viewpoint of location of hematomas. These are the tegmentobasilar type, tegmental type and basilar type. The tegmentobasilar type produces characteristic clinical features for pontine hemorrhage and poor prognosis, otherwise, another two types produce atypical clinical features for pontine hemorrhage and good prognosis.

Follicular dendritic cell sarcoma is a very rare neoplasm, which is not lymphoma, but originates from a type of immune cells called follicular dendritic cells. We presented a 37-year-old woman who has suffered from obstructive jaundice, weight loss and right upper abdominal pain for 2 months. The contrast CT revealed masses located in the region of pancreatic head and lots of enlarged retroperitoneal lymph nodes, both of which were enhanced on the artery phase of CT images. Meanwhile, Tc-HYNIC-TOC SPECT/CT revealed high activity in the corresponding lesions. After biopsy, the masses were pathologically confirmed as retroperitoneal follicular dendritic cell sarcoma.

Lower GI hemorrhage is a common source of morbidity and mortality. Tranexamic acid is an antifibrinolytic that has been shown to reduce blood loss in a variety of clinical conditions. Information regarding the use of tranexamic acid in treating lower GI hemorrhage is lacking. The aim of this trial was to determine the clinical efficacy of tranexamic acid when used for lower GI hemorrhage. This was a prospective, double-blind, placebo-controlled, randomized clinical trial. The study was conducted at a tertiary referral university hospital in Australia. Consecutive patients aged >18 years with lower GI hemorrhage requiring hospital admission from November 2011 to January 2014 were screened for trial eligibility (N = 265). A total of 100 patients were recruited after exclusions and were randomly assigned 1:1 to either tranexamic acid or placebo. The primary outcome was blood loss as determined by reduction in hemoglobin levels. The secondary outcomes were transfusion rates, transfusion volume, intervention rates for bleeding, length of hospital stay, readmission, and complication rates. There was no difference between groups with respect to hemoglobin drop (11 g/L of tranexamic acid vs 13 g/L of placebo; p = 0.9445). There was no difference with respect to transfusion rates (14/49 tranexamic acid vs 16/47 placebo; p = 0.661), mean transfusion volume (1.27 vs 1.93 units; p = 0.355), intervention rates (7/49 vs 13/47; p = 0.134), length of hospital stay (4.67 vs 4.74 d; p = 0.934), readmission, or complication rates. No complications occurred as a direct result of tranexamic acid use. A larger multicenter trial may be required to determine whether there are more subtle advantages with tranexamic acid use in some of the secondary outcomes. Tranexamic acid does not appear to decrease blood loss or improve clinical outcomes in patients presenting with lower GI hemorrhage in the context of this trial. see Video Abstract at http://links.lww.com/DCR/A453.

A retroperitoneal myxoid liposarcoma of the renal capsule must be differentiated from renal cell carcinomas, angiomyolipomas, fibrogenous lipomas, fibrolipomas and mixed tumours containing fat tissue. Myxoid liposarcomas can lead to intracavale tumourthromboses, which is often the case with renal cell carcinomas and revealed clinical with Budd-Chiari syndrome. Computed tomography and magnetic resonance imaging give additional information in the diagnosis of intracaval tumourthromboses and show the exact expansion of the topographic-anatomical structure.

Full Text Available The purpose of this study was to evaluate the efficacy and long-term complications of internal iliac artery embolization as a palliative measure in the control of intractable hemorrhage from advanced bladder malignancy. From January 1998 through December 2005, seven patients underwent transcatheter arterial embolization (TAE of anterior division of internal iliac artery bilaterally for intractable bladder hemorrhage. After embolization, patients were followed for the efficacy of the procedure in controlling hematuria and complications. TAE was successful in immediate control of severe hemorrhage in all seven patients after a mean period of 4 days. At a mean (range follow-up of 10 (6–12 months, the hemorrhage was permanently controlled in four (57% patients. Three patients developed hematuria and required emergency admissions; two had mild hematuria and were managed conservatively, and the remaining one required a second attempt of embolization after 2 months from the first one. During the whole period of follow-up, there were no significant complications related to embolization. Internal iliac artery embolization is an effective and minimally invasive option when managing advanced bladder malignancies presenting with intractable bleeding. The long-term follow-up showed control of bleeding in the majority of such patients with no serious complications.

Neuropeptide Y (NPY) is one of the most potent endogenous vasoconstrictors, and its contribution to the multifactorial cascade of cerebral vasospasm due to nontraumatic subarachnoid hemorrhage (SAH) is not yet fully understood. This experimental study compared the hemorrhage-specific course of NPY secretion into cerebrospinal fluid (CSF) and into plasma between 2 groups: patients with SAH and patients with basal ganglia hemorrhage (BGH) or cerebellar hemorrhage (CH) over the first 10 days after hemorrhage. Seventy-nine patients were prospectively included: SAH patients (n=66) (historic population) and intracerebral hemorrhage patients (n=13). All patients received an external ventricular drain within 24 hours of the onset of bleeding. CSF and plasma were drawn daily from day 1 to day 10. The levels of NPY were determined by means of competitive enzyme immunoassay. The CSF samples of 29 patients (historic population) who had undergone spinal anesthesia due to orthopedic surgery served as the control group. NPY levels in CSF were significantly higher in the 2 hemorrhage groups than in the control group. However, the 2 hemorrhage groups showed significant differences in NPY levels in CSF (SAH mean, 0.842 ng/mL vs. BGH/CH mean, 0.250 ng/mL; P<0.001) as well as in the course of NPY secretion into CSF over the 10-day period. NPY levels in plasma did not differ significantly among SAH, BGH/CH, and controls. Our findings support the hypothesis that excessive release of NPY into CSF but not into plasma is specific to aneurysmal SAH in the acute period of 10 days after hemorrhage. In BGH/CH, CSF levels of NPY were also increased, but the range was much lower.

To quantify the contribution of placenta accreta to the rate of postpartum hemorrhage and severe postpartum hemorrhage. All hospital deliveries in Canada (excluding Quebec) for the years 2009 and 2010 (N=570,637) were included in a retrospective cohort study using data from the Canadian Institute for Health Information. Placenta accreta included placental adhesion to the uterine wall, musculature, and surrounding organs (accreta, increta, or percreta). Severe postpartum hemorrhage included postpartum hemorrhage with blood transfusion, hysterectomy, or other procedures to control bleeding (including uterine suturing and ligation or embolization of pelvic arteries). Rates, rate ratios, population-attributable fractions (ie, incidence of postpartum hemorrhage attributable to placenta accreta), and 95% confidence intervals (CIs) were estimated. Logistic regression was used to quantify associations between placenta accreta and risk factors. The incidence of placenta accreta was 14.4 (95% CI 13.4-15.4) per 10,000 deliveries (819 cases among 570,637 deliveries), whereas the incidence of placenta accreta with postpartum hemorrhage was 7.2 (95% CI 6.5-8.0) per 10,000 deliveries. Postpartum hemorrhage among women with placenta accreta was predominantly third-stage hemorrhage (41% of all cases). Although placenta accreta was strongly associated with postpartum hemorrhage (rate ratio 8.3, 95% CI 7.7-8.9), its low frequency resulted in a small population-attributable fraction (1.0%, 95% CI 0.93-1.16). However, the strong association between placenta accreta and postpartum hemorrhage with hysterectomy (rate ratio 286, 95% CI 226-361) resulted in a population-attributable fraction of 29.0% (95% CI 24.3-34.3). Placenta accreta is too infrequent to account for the recent temporal increase in postpartum hemorrhage but contributes substantially to the proportion of postpartum hemorrhage with hysterectomy.

Predictive Value of CTA Spot Sign on Hematoma Expansion in Intracerebral Hemorrhage Patients

Directory of Open Access Journals (Sweden)

Wen-Jie Peng

2017-01-01

Full Text Available Hematoma expansion (HE occurs in approximately one-third of patients with intracerebral hemorrhage and leads to high rates of mortality and morbidity. Currently, contrast extravasation within hematoma, termed the spot sign on computed tomography angiography (CTA, has been identified as a strong independent predictor of early hematoma expansion. Past studies indicate that the spot sign is a dynamic entity and is indicative of active hemorrhage. Furthermore, to enhance the spot sign’s accuracy of predicting HE, spot parameters observed on CTA or dynamic CTA were used for its quantification. In addition, spot signs detected on multiphase CTA and dynamic CTA are shown to have higher sensitivity and specificity when compared with simple standardized spot sign detection in recent studies. Based on the spot sign, novel methods such as leakage sign and rate of contrast extravasation were explored to redefine HE prediction in combination with clinical characteristics and spot sign on CTA to assist clinical judgment. The spot sign is an accepted independent predictor of active hemorrhage and is used in both secondary intracerebral hemorrhage and the process of surgical assessment for hemorrhagic risk in patients with ischemic stroke. Spot sign predicts patients at high risk for hematoma expansion.

Eleven cases of neonatal intracranial hemorrhage were diagnosed and followed up by CT scanning. By CT, hemorrhagic lesions were shown as high density areas in an acute stage and imaged as low density areas after the hemorrhage was absorbed. The time of absorption varies depending upon the site and the severity of hemorrhage. Intraventricular hemorrhage, petechial hemorrhage and subdural hematoma were absorbed rapidly in more than 70% of the exanimed cases, CT scanning 1 - 2 weeks after the onset revealed absorption of hemorrhage. However, the absorption delayed in intracerebral hematoma; CT scan taken after one month showed hemorrhagic lesions remaining in 75% of the cases. In nine cases who survived, following the absorption of the hemorrhagic lesions, cerebral atrophy was observed in 4 cases (44%), ventricular enlargement in 3 cases (33%), and complete recovery in 2 cases (22%). From these results, CT scanning for diagnosis of neonatal intracranial hemorrhage should be done before the hemorrhagic lesion is absorbed (within 7 days of the onset). Follow-up study by CT is important for observing changes and predicting prognosis of intracranial hemorrhage. (Ueda, J.)

Neural Vascular Mechanism for the Cerebral Blood Flow Autoregulation after Hemorrhagic Stroke

Full Text Available During the initial stages of hemorrhagic stroke, including intracerebral hemorrhage and subarachnoid hemorrhage, the reflex mechanisms are activated to protect cerebral perfusion, but secondary dysfunction of cerebral flow autoregulation will eventually reduce global cerebral blood flow and the delivery of metabolic substrates, leading to generalized cerebral ischemia, hypoxia, and ultimately, neuronal cell death. Cerebral blood flow is controlled by various regulatory mechanisms, including prevailing arterial pressure, intracranial pressure, arterial blood gases, neural activity, and metabolic demand. Evoked by the concept of vascular neural network, the unveiled neural vascular mechanism gains more and more attentions. Astrocyte, neuron, pericyte, endothelium, and so forth are formed as a communicate network to regulate with each other as well as the cerebral blood flow. However, the signaling molecules responsible for this communication between these new players and blood vessels are yet to be definitively confirmed. Recent evidence suggested the pivotal role of transcriptional mechanism, including but not limited to miRNA, lncRNA, exosome, and so forth, for the cerebral blood flow autoregulation. In the present review, we sought to summarize the hemodynamic changes and underline neural vascular mechanism for cerebral blood flow autoregulation in stroke-prone state and after hemorrhagic stroke and hopefully provide more systematic and innovative research interests for the pathophysiology and therapeutic strategies of hemorrhagic stroke.

To assess the effectiveness and safety of uterine packing versus Foley's catheter tamponade for controlling postpartum hemorrhage (PPH) secondary to bleeding tendency after vaginal delivery. This was a prospective observational study conducted on 92 patients with primary PPH due to bleeding tendency following vaginal delivery who were unresponsive to uterotonics and bimanual compression of the uterus. Patients were divided into two groups, Uterine packing group (n = 45) and Foley catheter group (n = 47). The primary outcome was the success rate of the procedure. Secondary outcome addressed the maternal complications. The use of uterine packing resulted in stoppage of active bleeding in 93.3% of cases compared to only 68.1% in the Foley's catheter group (p  0.05). Six cases who failed to Foley catheter tamponade underwent emergency hysterectomy with no cases in the uterine packing group. The use of uterine packing to arrest PPH is simple, quick and safe procedure to avoid further surgical interventions and to preserve the fertility in low-resource setting.

1985-01-01

CT scan and fundus oculi of subarachnoid hemorrhage due to ruptured cerebral aneurysm were investigated in 42 patients who were admitted between January, 1980, and August, 1984. Fundal hemorrhage (FH) was observed in 22 patients. The patients with FH showed a worse clinical grade (Hunt Kosnik) on admission than those without FH. The mortality rate of patients with FH was 64 %, much higher than the 5 % rate of those without FH. Moreover, the patients with FH showed more trouble in daily living than those without FH. CT scans of patients with FH usually showed severe subarachnoid hemorrhage (SAH), whereas those of patients without FH showed only mild hemorrhage. These findings suggest that fundal hemorrhage is caused by acute intracranial hypertension following subarachnoid hemorrhage due to a ruptured cerebral aneurysm. However, no significant correlation between the laterality of FH and the hemispheric dominancy of SAH could be demonstrated. (author)

The purpose of this study was to analyze the angioarchitectures of cerebral arteriovenous malformation (AVM) and to determine whether there was correlation between angioarchitectures and patterns of intracranial hemorrhage (intracerebral, intraventricular, and both) in cerebral AVM. One hundred and twenty-eight patients who between November 1989 and December 1994 suffered supratentorial AVM with intracranial hemorrhage were studied retrospectively. Among 128 patients, intracerebral and intraventricular hemorrhage were seen in 68(53%) and 24 patients(19%), respectively, while both types were seen in the remaining 36 (28%). We analyzed the angioarchitectual characteristics of AVM, namely nidi, feeding arteries and draining veins, in three hemorrhagic groups of patients with intracerebral hemorrhage, intraventricular hemorrhage and both. The X 2 test or Fisher's exact test was used for statistical analysis. A cortically located nidus was most common in patients with intracerebral hemorrhage, while a periventricular location was most common in those with intraventricular hemorrhage (p<0.001). Location in the corpus callosum, choroid plexus, or intraventricular area was more frequent in the intraventricular than the intracerebral hemorrhagic group (p<0.05). Superficial venous drainage was most common in patients with intracerebral hemorrhage (p<0.001), and deep venous drainage in those with intraventricular hemorrhage (p=3D0.001). The angioarchitectual characteristics of cerebral arteriovenous malformation correlate significantly with patterns of intracranial hemorrhage, and awareness of the type of hemorrhage could help to manage patients and determine prognosis.=20

Full Text Available Hemorrhagic transformation (HT may occur as a part of the natural history of acute ischemic stroke, with incidence between 13-43% in computer-tomography (CT studies. Detection of HT in a patient with ischemic stroke is important in establishing treatment in the acute phase in assessing prognosis and in taking therapeutical decisions for secondary stroke prevention. There were controversies regarding optimal treatment in acute ischemic stroke with HT, especially if the patient needs further anticoagulant or antiplatelet treatment. Rehabilitation treatment needs to be continued for post-stroke patients who developed HT, because HT does not decrease rehabilitation outcome. We present rehabilitation treatment and prognosis in a case of hemorrhagic transformation after an embolic ischemic stroke treated with anticoagulants, which required reinitiation of anticoagulant treatment.

Rare aggressive behavior of MDM2-amplified retroperitoneal dedifferentiated liposarcoma, with brain, lung and subcutaneous metastases

2016-10-01

Full Text Available Dedifferentiated liposarcoma (DDL is a histologically pleomorphic sarcoma, traditionally defined as well-differentiated liposarcoma with abrupt transition to high grade, nonlipogenic sarcoma. It can occur as part of recurrent well-differentiated liposarcoma, or may arise de novo. DDL most frequently occurs within the retroperitoneum, and while it is prone to local recurrence, it usually has a lower rate of metastasis than other pleomorphic sarcomas. We describe a case of retroperitoneal dedifferentiated liposarcoma in a 63-year-old male, who showed MDM2 amplification with fluorescence in situ hybridization, which displayed unusually aggressive behavior, with brain, lung and subcutaneous soft tissue metastases. As previous reports of metastatic liposarcoma have largely grouped DDL in with other (genetically and clinically distinct liposarcoma subtypes, we highlight and discuss the rare occurrence of brain metastasis in MDM2-amplified retroperitoneal liposarcoma.

Full Text Available ABSTRACT Objectives The aim of our study is to present early outcomes of our series of retroperitoneal-RAPN (Robot Assisted Partial Nephrectomy. Materials and methods From September 2010 until December 2015, we performed 81 RAPN procedures (44 at left kidney and 37 at right. Average size was 3cm (1-9. Average PADUA score 7.1 (5-10. Average surgical time (overall and only robot time, ischemia time, blood loss, pathological stage, complications and hospital stay have been recorded. Results All of the cases were completed successfully without any operative complication or surgical conversion. Average surgical time was 177 minutes (75-340. Operative time was 145 minutes (80-300, overall blood loss was 142cc (60-310cc. In 30 cases the pedicle was late clamped with an average ischemia time of 4 minutes (2-7. None of the patient had positive surgical margins at definitive histology (49pT1a, 12pT1b, 3pT2a, 2pT3a. Hospital stay was 3 days (2-7. Conclusions The retroperitoneal robotic partial nephrectomy approach is safe and allows treatment of even quite complex tumors. It also combines the already well known advantages guaranteed by the da Vinci® robotic surgical system, with the advantages of the retroperitoneoscopic approach.

Full Text Available We report a case of immunoglobulin G4 (IgG4-related retroperitoneal fibrosis (RF with complete remission and no relapses after therapy with steroids and Hochuekkito, a Kampo (i.e. traditional Japanese herbal medicine. A 62-year-old Japanese man was admitted to our hospital for treatment of a retroperitoneal mass detected by computed tomography. The mass had a maximum diameter of 11.0 cm; it involved the left ureter and was associated with left hydronephrosis. After inserting a ureteral stent, we performed a biopsy by laparotomy. Histopathology revealed IgG4-related RF. The lesion disappeared after 7 months of steroid therapy. We subsequently used Hochuekkito as an alternative maintenance treatment because of steroid-related complications. The patient has not relapsed in the 3 years since starting the medication. To the best of our knowledge, this is the first case of IgG4-related RF treated with Hochuekkito as a maintenance treatment.

1981-01-01

A series of 44 patients with hypertensive cerebellar hemorrhage and nine patients with cerebellar hemorrhage caused by small angiomas is described. Hypertensive hemorrhage occurred most frequently in the patients in their seventies, whereas the onset of angioma-caused hemorrhage was often seen below the age of 40. Clinical syndromes of cerebellar hemorrhages can be categorized into three basic types: the vertigo syndrome, cerebellar dysfunction syndrome and brain stem compression syndrome. Patients with small (>= 2 cm in diameter in CT scans) and medium-sized (2 cm = 3 cm) hematomas deteriorated into unresponsive conditions and developed signs of brain stem compression. Surgical mortality was 32% in the hypertensive group, while it was 0% in the angioma group. Mortality as well as morbidity in both groups was strongly influenced by the preoperative status of consciousness. Our results suggest that substantial improvement could be obtained in the overall outcome of this disease by emergency craniectomy and removal of hematomas in all patients with large hematomas regardless of the levels of consciousness and regardless of the causes of bleeding. Furthermore, when clinical information and CT findings are suggestive of a ''cryptic'' angioma as the causative lesion, posterior fossa surgery may be indicated to extirpate the lesion, even if the hematoma is small.

Clinical aspects and prognosis of intraventricular hemorrhage with cerebrovascular disease

Ikeda, Yukio; Nakazawa, Shozo; Higuchi, Hiroshi; Ueda, Kenji; Kouzo

1982-01-01

Intraventricular hemorrhage with cerebrovascular disease was identified in 81 cases and death occurred within seven days in 34 cases. Hypertension was the most common etiological factor, accounting for 40 of the 81 cases. Cerebral aneurysm was the second most common cause accounting for 27 cases, arteriovenous malformation accounted for 9 of the cases, and 5 were of other causes. Signs of primary or secondary brain stem dysfunction were mainly seen in cases with hypertension and aneurysm, while cases with arteriovenous malformation had benign courses. The mortality depended on the severity of intraventricular hemorrhage; i.e., the distribution, site, and the number of cast formation. The presence of intraventricular clot in the third and/or fourth ventricles was correlated with a high mortality rate, especially in cases accompanied by cast formation and third and fourth ventricular dilatation, which affects hypothalamus and brain stem function. Analysis of CT findings for the mechanism of intraventricular hemorrhage revealed three types: extension type, in which massive intracerebral hematomas extended and ruptured into ventricles; the direct type, which bled directly into ventricles without forming definite intracerebral hematomas; and the reflux type, which was characterized by reflux of the subarachnoid blood.

Pelvic fractures may lead to severe retroperitoneal bleeding. Percutaneous catheter embolisation has become an increasingly important therapeutic alternative to surgical intervention. Most studies dealing with this problem have been small and we have attempted to evaluate the method on the basis of our own experience and a review of the literature. The success rate of percutaneous embolisation appears to be about 94%. The use of blood transfusion dropped from an average of 25.7 units before embolisation to an average of 6.5 units after embolisation. In spite of this, mortality in these patients remains high at 43.3% because of the serious additional injuries. The advantages and disadvantages of various embolising materials are discussed and various techniques of percutaneous embolisation are described. (orig.) [de

IgG4-related retroperitoneal fibrosis and sclerosing cholangitis independent of autoimmune pancreatitis. A recurrent case after a 5-year history of spontaneous remission.

Science.gov (United States)

Miura, Hideaki; Miyachi, Yasutaka

2009-07-06

A new clinicopathological concept of IgG4-related sclerosing disease affecting various organs has recently been proposed in relation to autoimmune pancreatitis. This report describes the case of IgG4-related retroperitoneal fibrosis and sclerosing cholangitis independent of autoimmune pancreatitis, which recurred after a long period of spontaneous remission. An 80-year-old Japanese man presented with obstructive jaundice owing to a hepatic hilum bile duct stricture. Coincidentally, a soft tissue mass surrounding the abdominal aorta, suggesting retroperitoneal fibrosis, was identified. Unexpectedly, spontaneous regression of obstructive jaundice together with retroperitoneal fibrosis occurred. The presence of high serum IgG4 concentrations measured later led us to consider a possible association with autoimmune pancreatitis; however, there were no clinical features confirming autoimmune pancreatitis. After a 5-year history of spontaneous clinical remission, there was an elevation of serum IgG4 levels and renal dysfunction owing to bilateral hydronephrosis caused by a reemergence of the retroperitoneal mass. Evaluation by endoscopic retrograde cholangiopancreatography revealed a biliary stricture, suggesting sclerosing cholangitis which was observed without the presence of any pancreatic duct abnormality. The subsequent excellent results obtained using steroid therapy, namely the decrease in serum IgG4 levels and the regression of the retroperitoneal mass, strongly suggested that the present case was an IgG4-related sclerosing disease. Aside from high serum IgG4 concentrations, markedly elevated levels of serum IgE was found retrospectively, although the clinical significance remains unknown. When we encounter fibrotic diseases of unknown etiology, we should measure serum IgG4 concentrations and monitor the disease activity over long periods even after achieving clinical remission.

MR of acute subarachnoid hemorrhage

Spickler, E.; Lufkin, R.; Frazee, J.; Lylyk, P.; Vinuela, F.; Bentson, J.; Dion, J.

1987-01-01

Subarachnoid hemorrhage was produced in four Macaca nemestrina monkeys using the technique of Frazee. CT and MR imaging was performed immediately after the procedure and at frequent intervals up to 2 weeks after hemorrhage. The imaging studies were compared with clinical evaluations and pathologic specimens of all animals. Additional human clinical CT/MR studies of subarachnoid hemorrhage were also studied. Acute hemorrhage was recognized on MR images as an increase in signal in the region of clot compared with surrounding cerebrospinal fluid. This most likely reflects T1 shortening due to proton binding rather than a pure paramagnetic effect. While CT is sensitive to the hemoglobin protein in acute hemorrhage, the superior resolution of MR of the basal cisterns results in equal or better definition of acute subarachnoid hemorrhage on MR studies in many cases

This study aims to investigate the application of the modified R.E.N.A.L. nephrometry score system in evaluating the operation difficulty of retroperitoneal partial nephrectomy in T1 renal cell carcinoma patients. A total of 52 patients with T1 renal cell carcinoma were enrolled. They all had retroperitoneal partial nephrectomy. Their clinical data was retrospectively analyzed. R.E.N.A.L. nephrometry score system was modified based on the features of retroperitoneal partial nephrectomy. The specificity, sensitivity and Youden index were compared between R.E.N.A.L. nephrometry score system and the modified R.E.N.A.L. nephrometry score system. The effect of the modified R.E.N.A.L. nephrometry score system on perioperative outcomes was analyzed. Three degrees of operation difficulty were defined by the modified R.E.N.A.L. nephrometry score system, which included the low, medium and high degree of operation difficulty. The specificity, sensitivity and Youden index of the modified R.E.N.A.L. nephrometry score system were better than those of the original R.E.N.A.L. nephrometry score system. Compared with low degree of operation difficulty, patients with medium and high degree of operation difficulty had significantly higher levels of operative time, warm ischemia time, and intraoperative blood loss (P system has a good effect in evaluating the operation difficulty of retroperitoneal partial nephrectomy.

Chronic expanding hematoma in the retroperitoneal space: a case report

Science.gov (United States)

2013-01-01

Background Chronic expanding hematoma is a rare condition that develops after surgery, trauma, or injury. It can also develop at any location in the body in the absence of trauma. Clinical findings and various diagnostic imaging modalities can aid in the differential diagnosis of this condition. In general, hematomas are naturally reabsorbed and rarely cause serious problems. However, hematomas that develop slowly without a history of trauma, surgery, or bleeding disorders could be difficult to differentiate from soft tissue neoplasms. In the present case, we describe a patient, without any history or physical evidence of trauma, who exhibited a large chronic expanding hematoma in the retroperitoneal space that resulted in hydronephrosis because of the pressure exerted on the left ureter. Case presentation A 69-year-old man presented to our hospital with a swollen lesion in the left flank. A mass, 19 cm in diameter, was detected in the retroperitoneal space by computed tomography. We suspected the presence of a chronic expanding hematoma, soft tissue tumor, or left renal artery aneurysm. Surgical treatment was performed. However, postoperative histopathological examination indicated that the mass was a nonmalignant chronic expanding hematoma. No recurrence was observed during a 2-year follow-up period. Conclusion In patients without a history of trauma who present slowly growing masses, the differential diagnosis should include chronic expanding hematoma in addition to cysts and soft tissue tumors. Moreover, the use of magnetic resonance imaging and computed tomography is essential to differentiate between chronic expanding hematoma and soft tissue tumors. PMID:24237992

[Multivisceral organ procurement for transplantation derived mobilization maneouvres: very helpful auxiliary techniques in the excision of large retroperitoneal masses].

2011-04-01

The excision of large retroperitoneal masses poses a challenge for every surgeon. Sometimes the urologist must face situations that do not fit to any conventional approach or technique previously described. Obtaining adequate exposure for safe and oncologically correct management of these masses is based, on many cases, in the mobilization of anatomical adjacent structures to generate a sufficient field in abdominal areas of difficult access. Complex visceral mobilization maneuvers derived from multivisceral transplantation organ procurement surgery provides ancillary techniques that used properly facilitate their successful resolution. The main purpose of this paper is the description of these surgical maneuvers essential to increase both exposure and vascular control in addressing the ever-dreaded high-volume retroperitoneal masses.

Full Text Available Numerous accounts documenting the introduction of foreign bodies into the urinary bladder have been reported. These foreign bodies are typically self-inserted via urethral but migration from adjacent organs by an ulcerative process and penetrating injuries are also reported. However, "contrary" migration of a self-inflicted vesical foreign body to the retroperitoneum was not previously reported in literature. We report here a case of a ballpoint pen self-inserted via urethral by a female patient, which was identified in retroperitoneal position years later.

The precise anatomic extent of the nematoma, associated cerebral edema, ventricular deformity and displacement, and hydrocephalus are all readily assessed. Aside from head trauma, the principal cause of intracerebral hematoma is hypertensive vascular disease. Although hematomas from various causes may present similar CT appearances frequently the correct etiology may be suggested by consideration of patient's age, clinical history, and the location of the hematoma. The analytical study was performed in 180 cases of intracerebral hemorrhages by CT from October 1981 to January 1983. The results were as follows; 1. The most prevalent age group was 6th decade (37.2%). Male was prevalent to female at the ration of 1.6 to 1. 2. The most common symptom and sign was mental disturbance (48.7%), motor weakness (23%), headache (10.6%), nausea and vomiting (9.8%). 3. The causes of hemorrhage were hypertension (53.9%), head trauma (30.6%), aneurysm (6.1%) and A-V malformation (7.2%). 4. The frequent locations of hemorrhage were basal ganglia and thalamus (40.4%), lobes (35%), ventricles (21.8%). 5. The distribution of hemorrhage was intracerebral hemorrhage (65.6%), intracerebral and intraventricular hemorrhage (30.3%), intraventricular hemorrhage (4.4%).

PurposeAcute hemorrhage associated with cancers of the head and neck is a life-threatening condition that requires immediate action. The aim of this study was to assess the safety and efficacy of endovascular embolization for acute hemorrhage in patients with head and neck cancers.Materials and MethodsData were retrospectively collected from patients with head and neck cancers who underwent endovascular embolization to treat acute hemorrhage. The primary endpoint was the rate of immediate control of hemorrhage during the first 24 h after embolization. The secondary endpoints were technical or clinical complications, rate of re-hemorrhage 24 h after the procedure, time from embolization to re-hemorrhage, hospitalization time, mortality rate, and time from embolization to death.ResultsFifty-one patients underwent endovascular embolization. The primary endpoint was achieved in 94% of patients. The rate of technical complications was 5.8%, and no clinical complication was observed. Twelve patients (23.5%) had hemorrhage recurrence after an average time of 127.5 days. The average hospitalization time was 7.4 days, the mortality rate during the follow-up period was 66.6%, and the average time from embolization to death was 132.5 days.ConclusionEndovascular embolization to treat acute hemorrhage in patients with head and neck cancers is a safe and effective method for the immediate control of hemorrhage and results in a high rate of hemorrhage control. Larger studies are necessary to determine which treatment strategy is best for improving patient outcomes.

1997-01-01

Cerebral hemodynamics in 15 patients with hypertensive intracerebral hemorrhage (HICH) were evaluated by measuring cerebral blood flow (CBF) and cerebrovascular reserve capacity, using stable xenon-enhanced computed tomography. Their hematomas were removed by stereotactic aqua stream aspiration. The hemispheric and thalamic CBFs of patients with HICH were lower than those of hypertensive patients without hematomas. However, the hemispheric CBF increased according to how much of the hematoma was removed surgically. Thus, hemodynamics in patients with HICH can be improved by surgical hematoma removal, although some adjunct therapies are necessary in order to prevent secondary edema and the delayed neuronal death.

Cerebral hemorrhage caused by amyloid angiopathy was studied clinicopathologically, with special attention given to the CT images. Cerebral hemorrhage caused by amyloid angiopathy is characterized, by a lobar-type hemorrhage involving the cortex, with direct extension into the subarachnoid space. Multiple hemorrhages are frequent, and cortical infarctions are present as complications in elderly patients without risk factors. CT scans taken in 5 cases demonstrated lobar hemorrhages in superficial locations, frequently in multiple sites or recurrently, with surrounding edema and mass effect. A subarachnoid extension of the hemorrhage through the superficial cortex, proven pathologically in all cases, was noted by CT in 4 of the 5 cases. However, cortical infarction was not detected by CT in any case. Therefore, CT is of value in the diagnosis of cerebral hemorrhage due to amyloid angiopathy based on distinctive findings such as a lobar hemorrhage in superficial regions, with extension into the subarachnoid space, frequently in multiple sites or recurrently.

The patient was a 66-year-old man. He lost consciousness as a result of a third subarachnoid hemorrhage attack. On neurological examination, he was found to be comatose and to have no spontaneous respiration. A mydriasis was noticed on both eyes. Bilateral retinal bleeding was also observed, with the bleeding of the left side more severe than that of the right side. After his death, his brain and eyes were examined by means of a CT scan. The CT films showed a severe subarachnoid hemorrhage and ventricular hematoma. The thin-sliced CT films showed left retinal bleeding. Retinal bleeding may be caused by a subarachnoid hemorrhage. Usually we make a sketch of the retinal bleeding on the basis of a doctor's report. A photo of an optic fundus is a good record; however, taking a photo is troublesome for severely ill patients. The CT finding of retinal bleeding is gross, but a CT image is one good way to record retinal bleeding. (author)

Hemorrhage into the brain of term newborns often results in major injury and lifelong disability. The clinical epidemiology of neonatal hemorrhagic stroke (NHS) remains undefined, hindering the development of strategies to improve outcomes. To characterize the incidence, types, presentations, associated factors, and outcomes of neonatal hemorrhagic stroke. Population-based, nested case-control study. The Alberta Perinatal Stroke Project, a provincial registry, ascertained NHS cases using exhaustive diagnostic code searching (1992-2010, >2500 medical record reviews). Prospective cases were captured through the Calgary Pediatric Stroke Program (2007-2014). Participants included term neonates with magnetic resonance imaging-confirmed NHS including primary and secondary intracerebral hemorrhage, hemorrhagic transformation of ischemic injury, and presumed perinatal hemorrhagic stroke. Control infants with common data were recruited from a population-based study (4 to 1 ratio). Infants with NHS underwent structured medical record review using data-capture forms and blinded scoring of neuroimaging. Clinical risk factor common data elements were explored using logistic regression. Provincial live births were obtained from Statistics Canada. Outcomes were extrapolated to the Pediatric Stroke Outcome Measure. We identified 86 cases: 51 infants (59%) with NHS, of which 32 (67%) were idiopathic, 30 (35%) were hemorrhagic transformation of primary ischemic injuries (14 with neonatal cerebral sinovenous thrombosis, 11 with hypoxic ischemic encephalopathy, and 5 with neonatal arterial ischemic stroke), and 5 were presumed perinatal hemorrhagic stroke. Sixty-two percent were male. Incidence of pure NHS was 1 in 9500 live births and 1 in 6300 for all forms. Most presented in the first week of life with seizures and encephalopathy. Acute neurosurgical intervention was rare (3 of 86 total cases; 3.5%). Temporal lobe was the most common NHS location (16 of 51 pure NHS cases; 31%). A

Peritoneal Dialysis and Retroperitoneal Laparoscopic Radical Nephrectomy: A Favorable Experience With a Patient Complicated by Renal Cell Carcinoma

Directory of Open Access Journals (Sweden)

Reika Imai

2017-12-01

Full Text Available Peritoneal dialysis (PD is an accepted modality for managing end-stage kidney disease. We herein report a 75-year-old female patient on chronic PD who was complicated by renal cell carcinoma. She was successfully treated with retroperitoneal laparoscopic radical nephrectomy followed by a prompt resumption of the procedure. Various surgeries disturbing the abdominal wall integrity often disrupt the regular PD schedule, and using minimally invasive approaches is therefore an attractive therapeutic option. Our experience emphasizes the feasibility and safety of a retroperitoneal approach–based laparoscopic technique based on several empirical examples. However, systemic studies on this topic are obviously lacking, so we strongly recommend the accumulation of more cases similar to our own. Several surgical concerns that need to be dealt with among PD patients are also discussed.

An adenocarcinoma arising from mature teratoma is one form of teratoma with malignant transformation. It is extremely rare but highly malignant. The authors report two patients with adenocarcinomas arising from primary retroperitoneal teratomas. The CT and MRI findings of the tumors are presented with emphasis on imaging features implying the presence of malignant transformation and differing from those of pure benign mature teratoma. Correct diagnosis of the presence of malignant transformation from a benign mature teratoma can be made as early as possible by awareness of the imaging features. (orig.)

Background: Postoperative remote cerebellar hemorrhage (RCH) as a complication of lumbar spinal surgery is an increasingly recognized clinical entity. The aim of this study was to determine the incidence of RCH after lumbar spinal surgery and to describe diagnostic imaging findings of RCH. Methods: Between October 1996 and March 2007, 2444 patients who had undergone lumbar spinal surgery were included in the study. Thirty-seven of 2444 patients were scanned by CT or MRI due to neurologic symptoms within the first 7 days of postoperative period. The data of all the patients were studied with regard to the following variables: incidence of RCH after lumbar spinal surgery, gender and age, coagulation parameters, history of previous arterial hypertension, and position of lumbar spinal surgery. Results: The retrospective study led to the identification of two patients who had RCH after lumbar spinal surgery. Of 37 patients who had neurologic symptoms, 29 patients were women and 8 patients were men. CT and MRI showed subarachnoid hemorrhage in the folia of bilateral cerebellar hemispheres in both patients with RCH. The incidence of RCH was 0.08% among patients who underwent lumbar spinal surgery. Conclusion: RCH is a rare complication of lumbar spinal surgery, self-limiting phenomenon that should not be mistaken for more ominous pathologic findings such as hemorrhagic infarction. This type of bleeding is thought to occur secondary to venous infarction, but the exact pathogenetic mechanism is unknown. CT or MRI allowed immediate diagnosis of this complication and guided conservative management.

hemorrhagic transformation is a threatening ischemic stroke complication. Frequency of hemorrhagic transformation differs greatly among studies, and its risk factors have been usually studied in patients with anterior ischemic stroke who received thrombolytic therapy. We evaluated, in a hospital-based series of patients with posterior ischemic stroke not treated with thrombolysis, frequency and risk factors of hemorrhagic transformation. Patients with posterior circulation stroke were seen in our Department during the period January 2004 to December 2009. Demographic and clinical information were collected. We estimated risk for spontaneous hemorrhagic transformation by means of uni- and multivariate logistic regression analyses. 119 consecutive patients were included (73 males, 61.3%). Hemorrhagic transformation was observed in 7 patients (5.9%). Only clinical worsening was significantly associated with hemorrhagic transformation (OR 6.8, 95% CI 1.3-34.5). Our findings indicate that patients with posterior have a low risk of spontaneous hemorrhagic transformation, suggesting that these patients might have greater advantage from intravenous thrombolysis.

Imaging of Hemorrhagic Stroke.

Hakimi, Ryan; Garg, Ankur

Hemorrhagic stroke comprises approximately 15% to 20% of all strokes. This article provides readers with an understanding of the indications and significance of various neuroimaging techniques available for patients presenting with hemorrhagic strokes of distinct causes. The most common initial neuroimaging study is a noncontrast head CT, which allows for the identification of hemorrhage. Once an intracranial hemorrhage has been identified, the pattern of blood and the patient's medical history, neurologic examination, and laboratory studies lead the practitioner to pursue further neuroimaging studies to guide the medical, surgical, and interventional management. Given that hemorrhagic stroke constitutes a heterogeneous collection of diagnoses, the subsequent neuroimaging pathway necessary to better evaluate and care for these patients is variable based on the etiology.With an increasing incidence and prevalence of atrial fibrillation associated with the aging population and the introduction of three new direct factor Xa inhibitors and one direct thrombin inhibitor to complement vitamin K antagonists, oral anticoagulant use continues to increase. Patients on oral anticoagulants have a sevenfold to tenfold increased risk for intracerebral hemorrhage (ICH). Furthermore, patients who have an ICH associated with oral anticoagulant use have a higher mortality rate than those with primary ICH. Despite the reduced incidence of hypertension-related ICH over the past decade, it is expected that the incidence of ICH will continue to increase. Neuroimaging studies are integral to the identification of hemorrhagic stroke, determination of the underlying etiology, prevention of hematoma expansion, treatment of acute complications, and treatment of the underlying etiology, if indicated. Neuroimaging is essential for prognostication and thus directly impacts patient care.

Cases of intracerebral hemorrhage except typical putamen thalamic hemorrhage were reported. It is not difficult to diagnose typical attacks of cerebral apoplexy in patients older than 40 years with hypertension by CT. When the condition of the onset is not typical, cerebral infarction must be considered. Though conservative treatment is performed for severe cerebral hemorrhage and cerbral infarction, there is no specific medicine curing these diseases completely. On the contrary, the risk that the administration of fibrinolysis activators and STA-MCA anastomosis may induce cerebral hemorrhage is stressed. Not a few patients with cerebral apoplexy accompanied by small hemorrhagic focuses have been found, especially since CT was used widely. However, treatment for this disease has many inconsistencies. From above-mentioned facts, we recognize excellent roles of CT in an application of surgery for cerebral hemorrhage of early stage, and we, general radiologists, are under an obligation to advise most adequate theraphy for each patient.

Retroperitoneal sarcomas (RPS) have fascinated and intrigued physicians both past and present. Operative mortality rates were historically very high and complete resection was not possible for the majority of patients until only the last 2 decades. More recently, changes to the surgical approach and clinical decision-making in RPS have improved patient outcomes. With select integration of nonsurgical therapies, continued RPS-specific research, and ongoing collaborative efforts among major referral centers, the future appears promising. © 2017 Wiley Periodicals, Inc.

To describe a case of necroulcerative gastritis in a cat secondary to administration of 3% hydrogen peroxide as an emetic agent. A 10-year-old neutered male domestic shorthair was evaluated for hematemesis less than 24 hours following ingestion of a piece of foam. The pet owner had administered 2 doses of 0.5-1.0 tablespoons (7.5-15 mL) of 3% hydrogen peroxide in an attempt to induce emesis at home; emesis was achieved and produced the foam foreign body. Due to the presence of protracted vomiting and hematemesis, the patient was then presented to an emergency facility for further diagnostics and treatment. Initial blood work was normal on presentation, and advanced imaging of the abdomen was performed. An exploratory laparotomy revealed no foreign material in the gastrointestinal tract; however, severe ulceration of approximately 60% of the gastric mucosa was observed around the cardia and extended from the fundus down through the body of the stomach to the lesser curvature. Due to the severity of ulceration and presumed poor prognosis, the patient was euthanized intraoperatively. Histopathology of the stomach wall was consistent with severe confluent necroulcerative and hemorrhagic pleocellular gastritis, presumed to be secondary to administration of 3% hydrogen peroxide, which was used as the primary emetic agent in this case. The oral administration of 3% hydrogen peroxide solution in cats can result in necroulcerative gastritis as a possible sequel. While hydrogen peroxide is considered a safe emetic agent in dogs, its use in cats is not recommended. As a result, the use of emetic agents in cats should be limited to veterinary administration, using alternative, safer emetic agents such as alpha-adrenergic agonists. © Veterinary Emergency and Critical Care Society 2017.

In tracranial hemorrhage in leukemia was clinicopathologically studied in 62 cases of autopsy materials, with special attention paid to a morphological comparison of CT images with pathological findings. Intracranial hemorrhage was found in 32 of the 62 leukemic patients (51.6%), and in 13 of these patients (21.0%) it was responsible for death. Leukemic intracranial hemorrhage occurred more often in the acute leukemic type than in the chronic type, and even more often in younger leukemic patinents; it was pathologically characterized by multiple lesions in the white matter of the cerebral hemisphere, prone to combination with SAH or SDH. The hemorrhages could be divided into five types: (1) scattered small hemorrhagic type, (2) hematoma type, (3) fusion type (large hemorrhage composed of assembled small hemorrhages), (4) SAH type, and (5) SDH type. Among these types, the fusion type was considered to be characteristic of leukemia. CT was undertaken in 5 pathologically proven cases, with findings of the scattered small hemorrhagic type in 1, of the SDH type in 3, and of the fusion type in 1. Yet, one case with scattered small hemorrhages and two cases with SDH failed to be detected by CT. However, one case with a typical fusion hemorrhage was found to have multiple, irregular, high-density areas with surrounding edema and a mass effect as well as pathological findings. Therefore, a large-fusion hemorrhage, which is one of the most characteristic types of leukemic intracranial hemorrhage, could be demonstrated as distinctive CT images which reflected neuropathological findings. On the other hand, small parenchymal hemorrhages and relatively thin subdural hemorrhages could not be detected by CT. In conclusion, it seems that CT has value in the diagnosis of intracranial hemorrhage in leukemia. (J.P.N.)

Full Text Available Abstract Background The objective of this study was to develop a modified retroperitoneal laparoscopic nephrectomy and compare its results with the previous technique. Methods One hundred retroperitoneal laparoscopic nephrectomies were performed from February 2007 to October 2011. The previous technique was performed in 60 cases (Group 1. The modified technique (n = 40 included fast access to the renal pedicle according to several anatomic landmarks and early ligation of renal vessels (Group 2. The mean operation time, mean blood loss, duration of hospital stay conversion rate and complication rate were compared between the groups. Results No significant differences were detected regarding mean patient age, mean body mass index, and tumor size between the two groups (P >0.05. The mean operation time was 59.5 ± 20.0 and 39.5 ± 17.5 minutes, respectively, in Groups 1 and 2 (P P P >0.05. Conclusions Early ligature using fast access to the renal vessels during retroperitoneal laparoscopic radical nephrectomy contributed to less operation time and intraoperative blood loss compared with the previous technique. In addition, the modified technique permits the procedure to be performed following the principles of open radical nephrectomy.

The effectiveness of pharmacological strategies exclusively targeting secondary brain damage (SBD) following ischemic stroke, aneurysmal subarachnoid hemorrhage, aSAH, intracerebral hemorrhage (ICH), traumatic brain injury (TBI) and bacterial meningitis is unclear. This meta-analysis studied the effect of SBD targeted treatment on clinical outcome across the pathological entities. Randomized, controlled, double-blinded trials on aforementioned entities with 'death' as endpoint were identified. Effect sizes were analyzed and expressed as pooled risk ratio (RR) estimates with 95% confidence intervals (CI). 123 studies fulfilled the criteria, with data on 66,561 patients. In the pooled analysis, there was a minor reduction of mortality for aSAH [RR 0.93 (95% CI:0.85-1.02)], ICH [RR 0.92 (95% CI:0.82-1.03)] and bacterial meningitis [RR 0.86 (95% CI:0.68-1.09)]. No reduction of mortality was found for ischemic stroke [RR 1.05 (95% CI:1.00-1.11)] and TBI [RR 1.03 (95% CI:0.93-1.15)]. Additional analysis of "poor outcome" as endpoint gave similar results. Subgroup analysis with respect to effector mechanisms showed a tendency towards a reduced mortality for the effector mechanism category "oxidative metabolism/stress" for aSAH with a risk ratio of 0.86 [95% CI: 0.73-1.00]. Regarding specific medications, a statistically significant reduction of mortality and poor outcome was confirmed only for nimodipine for aSAH and dexamethasone for bacterial meningitis. Our results show that only a few selected SBD directed medications are likely to reduce the rate of death and poor outcome following aSAH, and bacterial meningitis, while no convincing evidence could be found for the usefulness of SBD directed medications in ischemic stroke, ICH and TBI. However, a subtle effect on good or excellent outcome might remain undetected. These results should lead to a new perspective of secondary reactions following cerebral injury. These processes should not be seen as suicide mechanisms

Full Text Available Posthemorrhagic anemia is a rare but important cause of anemia in neonates, second only to hemolytic anemia of newborn. Most cases of posthemorrhagic anemia are reported from fetomaternal hemorrhage or umbilical cord accidents in utero. This case report describes a preterm infant who developed severe anemia and shock immediately after delivery related to an acute hemorrhage through patent umbilical cord vessels secondary to a tear in the umbilical cord at the site of cord clamping. We believe that umbilical cord bleeding from errors in cord clamping could be an important cause of acute blood loss in the delivery room and that it may result in significant clinical morbidity, especially in extremely premature infants.

To perform arterial or venous spleno-renal anastomoses, surgeons have so far systematically used the transperitoneal way whic is burdened by a high mortality an morbility percentage. On the basis of anatomo-surgical considerations, a retroperitoneal approach has been found reaching the hilus of the spleen via the lumbar region; the first arterial spleno-renal anastomosis by this way was performed in 1972 and the first venous spleno-renal anastomosis due to portal hipertension also by this way was performed in 1974, the alter proving to be the least aggresive by avoiding damaging the páncreas, the most surgical and direct for reaching the splenic vessels thereby enabling a better exposure and an easier performing of the anastomoses. By being retroperitoneal, the loss or infección of the ascitic liquid in the cirrhotic patient is prevented.

Computed tomography has been established as an indispensable tool in the detection of intracranial hemorrhages. Extra axial fluid collections are usually easily distinguished from intracerebral hemorrhages. However, hemorrhages in atypical locations, such as in falx and tentorial regions, can be difficult to diagnose with CT. The tentorial and falcial collection of subdural blood are rather unusual. Authors report here 84 cases of falcial and tentorial subdural hemorrhages with reference data that we have encountered in the last two years. The results were as follows; 1. In 589 cases of intracranial hemorrhage, the incidence of subdural hemorrhage was 372 cases (63.2%). 2. Among 372 cases with subdural hemorrhage, 84 cases (22.6%) had falcial and/or tentorial subdural hemorrhage. In 84 cases with falcial and/or tentorial subdural hemorrhage, there were 50 cases (13.4%) of falcial subdural hemorrhages, 21 cases (5.7%) of tentorial subdural hemorrhage and 13 cases (3.5%) of combined falcial and tentorial subdural hemorrhage. 3. The location of falcial subdural hemorrhage was anterior in 30 cases (60%), posterior in 15 cases (30%) and middle in 5 cases (10%). 4. The location of tentorial subdural hemorrhage was petrous edge in 7 cases (33.3%), occipital attachment in 6 cases (28.6%), tentorial hiatus in 5 cases (23.8%), and diffuse in 3 cases (14.3%). 5. In 13 cases showing combined falcial and tentorial subdural hemorrhage, there was 3 cases (23.1%) of posterior falx and tentorial hiatus, 2 cases (15.4%) of anterior falx and petrous edge, 2 cases of anterior falx and tentorial hiatus, 2 cases of posterior falx and petrous edge, 2 cases of posterior falx and occipital attachment, 1 case (7.7%) of posterior falx and diffuse, and 1 case of posterior, middle falx and diffuse. 6. In the cases with falcial and/or tentorial subdural hemorrhage, the incidence of associated intracranial hemorrhage were intracrania subdural hemorrhage in 40 cases (47.6%), hemorrhagic brain

Full Text Available Cardiogenic embolism is a major cause of stroke and often leads to significant morbidity and mortality. Despite the recent advances in our understanding of the pathophysiology of stroke and its risk factors, diagnosis and therapy; some case scenarios still present a real challenge for the treating physicians. We report a case of a 50 year old male patient presenting with multi-territory cerebral infarctions due to a left ventricular mobile thrombus complicated with hemorrhagic transformation at the time of presentation. Gradual introduction of anticoagulation coupled with a multidisciplinary team approach advocating careful daily clinical assessment of the patient and regular echocardiographic and neuroimaging studies have resulted in a better management and achievement of therapeutic goals.

Intraretinal hemorrhages in cystoid macular edema.

Bovino, J A; Kelly, T J; Marcus, D F

1984-08-01

Retinal hemorrhages can be associated with typical cystoid macular edema. We examined the fundus photographs and fluorescein angiograms of 313 eyes of 264 patients with documented cystoid macular edema to establish the incidence and characteristics of associated intraretinal hemorrhages. As we wanted to study only those hemorrhages unique to cystoid macular edema, we excluded 86 eyes because the patients had diseases known to be associated with retinal hemorrhages. These diseases included diabetes mellitus, branch retinal vein occlusion, hypertensive retinopathy, venous stasis retinopathy, and perifoveal telangiectasia. Of the remaining 227 eyes with cystoid macular edema, 56 (24.7%) were identified with retinal hemorrhages not associated with systemic disease. The hemorrhages were characteristically oval, round, or linear and frequently filled or partially filled the intraretinal cystoid space. In many patients, a blood-fluid level was observed.

MR imaging of acute subarachnoid hemorrhage

1987-01-01

Subarachnoid hemorrhage was produced in four Macaca nemestrina monkeys using the technique of Frazee. CT and MR imaging were performed immediately after the procedure and at frequent intervals up to 2 weeks after hemorrhage. The imaging studies were compared with clinical evaluations and pathologic specimens of all animals. Additional human clinical CT/MR studies of subarachnoid hemorrhage were also studied. Acute hemorrhage was recognized on MR as an increase in signal in the region of clot compared with surrounding cerebrospinal fluid. This most likely reflects T1 shortening due to proton binding rather than a pure paramagnetic effect. While CT is sensitive to the hemoglobin protein in acute hemorrhage, the superior resolution of the basal cisterns on MR images results in equal or better definition of acute subarachnoid hemorrhage on MR in many cases

Intracranial hemorrhage of the mature newborn infant

Takemine, Hisao

1983-01-01

Concerning four mature newborn infants with intracranial hemorrhage diagnosed by CT, the labour course, treatment, and prognoses were discussed. Of intracranial hemorrhage, 70.7% was small hemorrhage along the cerebellar tentorium and the falx cerebri, 12.2% subdural hemorrhage in the posterior cranial fossa, and 9.8% subdural hemorrhage in the fornex. Intraventricular or extradural hemorrhage was rarely found. The prognosis is determined by severeness of neurotic symptoms due to cerebral hypoxia. Subdural hemorrhage of the posterior cranial fossa resulted in cerebral palsy in one fifth of the cases, and in slight enlargement of the ventricle in three fifths. Subdural hematoma left porencephaly in one fourth of the patients, but the remaining recovered to normal. (Ueda, J.)

Full Text Available Introduction. Abnormal uterine hemorrhages (AUH are the most common symptom for presentation to gynecologist. Any uterine bleeding other than menstrual bleeding, which concerns the duration, frequency, quality or quantity of the bleeding is considered abnormal. Material and Methods. We realized a retrospective study based on medical records of the patients admitted for abnormal uterine hemorrhage at “Saint John” Emergency Clinical Hospital, “Bucur” Maternity between 2013 and 2016. From the patients with AUH, we focused on those who underwent hysteroscopies. Results. Our study included 146 patients. The age of patients varied from 22 to 71 years. Abnormal uterine bleeding was most prevalent among women of 40-50 years (20%, and the mean age was 42.65%. 82.88% from our patients had obstetrical history and only 17.12% didn’t give birth either as an option, or from primary or secondary infertility. 7.53% of the patients were hypertensive and 5.48% had endocrine pathology. All patients underwent diagnostic hysteroscopy and 4.79% patients therapeutic hysteroscopy. The therapeutic measures that were made are: hysteroscopic resection of the endometrium (47.3%, excision of polyps (36.99%, sinechiolysis (8.22% and myomectomy (2.71%. The diagnoses were 46.48% endometrial polyp, 13.7% intramural leiomyoma, 13.7% IUD (intrauterine device and 9.59% intrauterine synechiae, while 15.06% cumulated for uterine septum, endometrial hyperplasia, cervical polyp, foreign intrauterine bodies, secondary infertility, dysfunctional metrorrhagia. Conclusion. In patients with abnormal uterine hemorrhages, hysteroscopy provides the most accurate diagnosis and can reduce the burden of hysterectomy in many cases.

Gray scale ultrasonography of the kidneys were performed in 30 patients with KHF., significant morphologic changes were noted representing the pathologic involvement of the kidneys, and aids in the clinical assessment of severity of the diseases. 1. Peak increased renal volume is seen in oliguric stage. 2. Renal cortical echogenicity is increased in oliguric stage, and returned to normal in convalescency. 3. Medullary pyramid enlargement is seen mainly in diuretic stage. 4. Retroperitoneal edema and thickening of renal capsule are noted in oliguric stage. 5. Abnormal fluid accumulation was seen in two-third of cases in the peritoneal and perirenal space only in oliguric stage. Renal sonography is simple, non hazardous modality, providing satisfactory information about the renal and retroperitoneal anatomy

Way, D; Hendrix, M; Witte, M; Witte, C; Nagle, R; Davis, J

1987-09-01

An endothelial cell line derived from a massive recurrent chyle-containing retroperitoneal lymphangioma was isolated in monolayer culture. Scanning and transmission electron microscopy and immunohistochemistry confirmed a close resemblance to blood vascular endothelium with typical cobblestone morphology, positive immunofluorescence staining for endothelial marker Factor VIII-associated antigen and fibronectin, and prominent Weibel-Palade bodies. The endothelial cells also exhibited other ultrastructural features characteristic of lymphatic endothelium, including sparse microvillous surface projections, overlapping intercellular junctions, and abundant intermediate filaments. This endothelial cell line represents a new source of proliferating lymphatic endothelium for future study, including structural and functional comparison to blood vascular endothelium.

Intraduodenal sarcoma recurrence of retroperitoneal origin: an unusual cause for a duodenal obstruction

Directory of Open Access Journals (Sweden)

Bao Jean J

2012-04-01

Full Text Available Abstract Soft tissue sarcomas are uncommon tumors, and intraduodenal soft tissue sarcoma manifestation is even more rare. Only three cases of intraduodenal sarcomas have been reported in the literature thus far. Here, we report a case of an intraduodenal recurrence of a retroperitoneal sarcoma causing bowel obstruction. This unusual recurrence pattern likely relates to the patient’s previous resection and radiation treatment, and highlights the benefits, limitations and follow-up strategies after multimodality treatment.

Thirty-two of 290 neonates admitted to the Perinatal Intensive Care Unit, Toho University Medical School, were examined by CT scan because of tentative clinical diagnosis of intracranial hemorrhage. CT scanner employed in this study was TCT-60 A from the Toshiba The Electric Co., Ltd. Fourteen cases (44%) were confirmed by the CT scan to have intracranial hemorrhage. Four cases had hemorrhage in the ventricle, while the remaining ten cases had subarachnoid hemorrhage. Subdural hemorrhage was not revealed in our series. Three of the four cases with intraventricular hemorrhage showed a typical subependymal germinal matrix hemorrhage. The prognosis of intraventricular hemorrhage in neonates seemed to be poor; two of the four cases died within a week. Their body weight at birth was apparently under the standard, and their Apgar score was 3 points. The subarachnoid hemorrhage was the main type of intracranial neonatal hemorrhages. In our series, it was constituted approximately 70% of the intracranial hemorrhages. The CT images of the subarachnoid hemorrhage in neonate were greatly different from those in adults. An irregular, wide high-density area around the falxtentorial junction was characteristic of the CT in many neonatal subarachnoid hemorrhages. In severe subarachnoid hemorrhages, a characteristic Y-shaped, high-density figure was demonstrated. In cases of subarachnoid hemorrhage from the deep venous system, high-density spreading immediately ventral to the falx-tentrium junction was demonstrated. These high-density areas due to blood in the subarachnoid space rapidly disappeared with the lapse of time. On the other hand, high-density areas in cerebral cisterns and/or fissures were rarely demonstrated in neonatal subarachnoid hemorrhages. The prognosis of subarachnoid hemorrhage in neonates was fairly good in the sense of life and cerebral functions. (author)

Hemorrhagic Lacrimation and Epistaxis in Acute Hemorrhagic Edema of Infancy

Full Text Available Acute hemorrhagic edema of infancy is an uncommon benign cutaneous vasculitis. Despite its worrisome presentation, it carries good prognosis with rarely reported systemic involvement. Management of these cases has been an area of debate with majority of physicians adopting conservative modalities. We report a case that presented with classic triad of rash, low grade fever, and peripheral edema along with two rarely reported manifestations in literature: hemorrhagic lacrimation and epistaxis.

Unraveling the distinctive features of hemorrhagic and non-hemorrhagic snake venom metalloproteinases using molecular simulations

de Souza, Raoni Almeida; Díaz, Natalia; Nagem, Ronaldo Alves Pinto; Ferreira, Rafaela Salgado; Suárez, Dimas

2016-01-01

Snake venom metalloproteinases are important toxins that play fundamental roles during envenomation. They share a structurally similar catalytic domain, but with diverse hemorrhagic capabilities. To understand the structural basis for this difference, we build and compare two dynamical models, one for the hemorrhagic atroxlysin-I from Bothrops atrox and the other for the non-hemorraghic leucurolysin-a from Bothrops leucurus. The analysis of the extended molecular dynamics simulations shows some changes in the local structure, flexibility and surface determinants that can contribute to explain the different hemorrhagic activity of the two enzymes. In agreement with previous results, the long Ω-loop (from residue 149 to 177) has a larger mobility in the hemorrhagic protein. In addition, we find some potentially-relevant differences at the base of the S1' pocket, what may be interesting for the structure-based design of new anti-venom agents. However, the sharpest differences in the computational models of atroxlysin-I and leucurolysin-a are observed in the surface electrostatic potential around the active site region, suggesting thus that the hemorrhagic versus non-hemorrhagic activity is probably determined by protein surface determinants.

Friedman, Jonathan A.; Kallmes, David F.; Wijdicks, Eelco F.M.

2004-01-01

Carotid angioplasty and stenting (CAS) has emerged as an alternative treatment of carotid stenosis for patients poorly suited for endarterectomy. Intracerebral hemorrhage following carotid revascularization is rare and thought to be related to hyperperfusion injury in most cases. Early experience suggests an increased incidence of hemorrhage following CAS as compared to endarterectomy. We describe a patient who suffered a thalamic hemorrhage following CAS. Because this hemorrhage occurred in a vascular territory unlikely to have been supplied by the treated artery, this case suggests that the mechanism of intracerebral hemorrhage following CAS may in some cases be different from the hyperperfusion hemorrhage classically described following endarterectomy.

Patients diagnosed with retroperitoneal sarcoma at the Hospital San Juan de Dios were characterized during the years 2007 to 2012. The population framework was taken from the hospital's Pathology service database. A total of 15 patients older than 12 years with a diagnosis of sarcoma or malignant fibrous histiocytoma and that the site of origin of the biopsy was the retroperitoneum were selected. The data of the selected patients were collected through a data collection form. The variables included were: age, sex, origin, dates of importance (income, discharge, surgery, complication), presence and type of complications, pathological staging, type of surgery, comorbidities, presence and date of recurrence, treatment with chemotherapy and radiotherapy, death and causes of death. A descriptive analysis with the calculation of frequency measurements (absolute and relative) was carried out to describe the occurrence of the event. The analysis of proportional risks was performed considering the relationship between death and time, the possible relationship with the service of approach, clinical stage and resection status was also assessed. Information on diagnosis, evaluation, staging and management of retroperitoneal sarcomas is cited in the theoretical framework [es

Plain film radiography shows a lytic lesion in the sternum side of the clavicle. biopsy reports a plasmacytomas, radiotherapy was performed. Three years later lesions of similar characteristics within ribs and a focal lesion in left testicle were detected. The diagnosis was multiple myeloma, Chemotherapy and orquidectomy were performed. One year after, patient complained of diffuse abdominal pain and loss weight, contrast abdominal CT was performed. Computed tomography showed a left heterogeneous mass with irregular contours that involved the retroperitoneal space occupying its three compartments. Biopsy was performed and reported pleomorphicplasmocytic proliferation with nuclear enlargement and hyperchromic nuclei consistent with multiple myeloma with abdominal involvement.

Solitary Bone Plasmacytoma Progressing into Retroperitoneal Plasma Cell Myeloma with No Related End Organ or Tissue Impairment: A Case Report and Review of the Literature

Full Text Available Solitary bone plasmacytomas and plasma cell myeloma are clonal proliferations of plasma cells. Many patients with solitary bone plasmacytomas develop plasma cell myeloma on follow-up. We present a case of a 70-year-old man who presented with fracture and a lytic lesion in the subtrochanteric region of the left femur and was assigned a diagnosis of solitary bone plasmacytoma. He received local curative radiotherapy. However, 4 months later his serum M protein and β2-microglobulin levels increased to 2.31 g/dL and 5.965 mg/L, respectively. He complained of abdominal fullness and constipation. Ultrasound and non-contrast CT imaging revealed multiple retroperitoneal masses. Colonoscopic examination was normal. Biopsy of the a retroperitoneal mass confirmed it to be a plasmacytoma. Repeat hemogram, blood urea, serum creatinine, skeletal survey, and bone marrow examination revealed no abnormalities. This is an unusual presentation of plasma cell myeloma, which manifested as multiple huge extramedullary retroperitoneal masses and arose from a solitary bone plasmacytoma, without related end organ or tissue impairment and bone marrow plasmacytosis. The patient succumbed to his disease 8 months after the appearance of the retroperitoneal masses. This case highlights the importance of close monitoring of patients diagnosed with solitary bone plasmacytoma with increased serum M protein and serum β2-microglobulin levels, so that early therapy can be instituted to prevent conversion to plasma cell myeloma.

Hemorrhage and vascular abnormalities

International Nuclear Information System (INIS)

Bradley, W.G.

1990-01-01

While many brain lesions have a similar appearance on MRI and CT, this is not true of hemorrhage. On CT, acute hemorrhage becomes hyperdense within an hour as the clot forms. This lasts for several days and then fades to isodensity and eventually hypodensity. On MRI, hemorrhage less than 12 to 24 hours old may not be distinguishable from vasogenic edema. Its appearance subsequently is an evolving pattern of variable signal intensity which depends on the specific form of hemoglobin which is present, or whether the red cells are intact or lysed, on the operating field strength, on the type of signal (that is, spin echo or gradient echo), and on contrast (that is, T 1 - or T 2 -weighing). The appearance of hemorrhage also depends on the compartment of the brain involved---subarachnoid, subdural, or intraparenchymal. Finally, for parenchymal hematomas, different zones may be defined from the inner core to the outer rim which all vary in appearance depending on field strength and imaging technique

Retrospective evaluation of interventional embolization therapy in the treatment of gastrointestinal hemorrhage over a long-term observation period from 1989 to 1997. Included in the study were 35 patients (age range 18-89 years) with gastrointestinal bleeding (GI) referred for radiological intervention either primarily or following unsuccessful endoscopy or surgery. Sources of GI bleeding included gastric and duodenal ulcers (n = 7), diverticula (n = 3), erosion of the intestinal wall secondary to malignancy (n = 6), vascular malformations (n = 4), and hemorrhoids (n = 2), as well as from postoperative (n = 6), posttraumatic (n = 2), postinflammatory (n = 4) or unknown (n = 1) causes. Ethibloc (12 cases) or metal coils (14 cases) were predominantly used as embolisates. In addition, combinations of tissue adhesive and gelfoam particles and of coils and Ethibloc were used (six cases). Finally, polyvinyl alcohol particles, a coated stent, and an arterial wire dissection were utilized in one case each. Bleeding was stopped completely in 29 of 35 cases (83 %). In one case (3 %) the source of bleeding was recognized but the corresponding vessel could not be catheterized. In five other cases (14 %) there was partial success with reduced, though still persistent, bleeding. The rate of complications was 14 %, including four instances of intestinal ischemia with fatal outcome in the first years, and, later, one partial infarction of the spleen without serious consequences. Gastrointestinal hemorrhage can be controlled in a high percentage of patients, including the seriously ill and those who had previously undergone surgery, with the use of minimally invasive interventional techniques. The availability of minicoils instead of fluid embolization agents has reduced the risk of serious complications. (orig.)

Intracerebral hemorrhage in brain tumors

International Nuclear Information System (INIS)

Fujita, Katsuzo; Matsumoto, Satoshi

1980-01-01

A series of 16 cases of intracerebral hemorrhage associated with brain tumors are described. The literature is reviewed and the incidence of these cases is reported to be low, but we had clinically encountered these cases more commonly than reported, since CT was introduced to the neurosurgical field as a diagnostic aid. The presenting symptoms were those of spontaneous intracerebral hemorrhage or brain tumor. The intracerebral hemorrhage associated with brain tumor may mask the cause of bleeding and confuse the diagnosis. The majority of the tumor causing the intracerebral hemorrhage are highly malignant as glioblastoma or metastatic brain tumor, but there are some benign tumors such as pituitary adenoma, hemangioblastoma, benign astrocytoma and meningioma, which would have good survival rates if discovered early. The mechanisms of massive hemorrhage with brain tumor are not clear. From pathological findings of our cases and other reports, the mechanism seems to be due to the vascular endothelial proliferation with subsequent obliteration of the lumen of the vessel. Thin walled, poorly formed vessels in tumor may also become distorted with growth of the tumor and these may easily rupture and bleed. Necrosis with subsequent loss of vessel support may be a factor in production of hemorrhage. Radiation therapy may be a predisposing factor. Children are rarely involved in these cases. The prognosis in the majority of cases would seen to be poor, since the majority of the tumor are highly malignant and most such patients are seen by the neurosurgeon some time after the hemorrhage has accomplished its fatal mischief.

Viral hemorrhagic septicemia (VHS) is one of the most important viral diseases of finfish worldwide. In the past, VHS was thought to affect mainly rainbow trout Oncorhynchus mykiss reared at freshwater facilities in Western Europe where it was known by various names including Egtved disease and infectious kidney swelling and liver degeneration (Wolf 1988). Today, VHS is known as an important source of mortality for cultured and wild fish in freshwater and marine environments in several regions of the northern hemisphere (Dixon 1999; Gagné et al. 2007; Kim and Faisal 2011; Lumsden et al. 2007; Marty et al. 1998, 2003; Meyers and Winton 1995; Skall et al. 2005b; Smail 1999; Takano et al. 2001).

Serial cranial ultrasound studies, 133xenon inhalation cerebral blood flow determinations, and risk factor analyses were performed in 31 preterm neonates. Contrast echocardiographic studies were additionally performed in 16 of these 31 infants. Sixty-one percent were found to have germinal matrix or intraventricular hemorrhage. Seventy-four percent of all hemorrhages were detected by the thirtieth postnatal hour. The patients were divided into three groups: early GMH/IVH by the sixth postnatal hour (eight infants) interval GMH/IVH from 6 hours through 5 days (10), and no GMH/IVH (12). Cerebral blood flow values at 6 postnatal hours were significantly lower for the early GMH/IVH group than for the no GMH/IVH group (P less than 0.01). Progression of GMH/IVH was observed only in those infants with early hemorrhage, and these infants had a significantly higher incidence of neonatal mortality. Ventriculomegaly as determined by ultrasound studies was noted equally in infants with and without GMH/IVH (50%) and was not found to correlate with low cerebral blood flow. The patients with early hemorrhage were distinguishable by their need for more vigorous resuscitation at the time of birth and significantly higher ventilator settings during the first 36 postnatal hours, during which time they also had higher values of PCO2. An equal incidence of patent ductus arteriosus was found across all of the groups. We propose that early GMH/IVH may be related to perinatal events and that the significant decrease in cerebral blood flow found in infants with early GMH/IVH is secondary to the presence of the hemorrhage itself. Progression of early GMH/IVH and new interval GMH/IVH may be related to later neonatal events known to alter cerebral blood flow

Headache-like Subarachnoid Hemorrhage After Digital Subtraction Angiography: A Case Report

Full Text Available Subarachnoid hemorrhage (SAH is a clinical condition with acute-onset, sudden, and severe headache. In addition to headache, severe nausea, vomiting, dizziness, confusion, agitation, focal neurologic deficits, and hypertension can be detected. Findings of meningeal irritation may accompany to these clinical features, 6-24 hours after the hemorrhage. Digital subtraction angiography (DSA is used for surgical or endovascular treatment planning in order to identify vascular abnormalities, in addition to other imaging studies. After DSA, the frequency of all neurologic complications is between 0.2% and 4.5%. Headache may occur after DSA in an average 50% of patients. This rate is especially higher in female patients. Headache types are usually classified as migraine, tension or postoperative atypical headaches The incidence of severe headache after DSA is low. Vascular wall rupture should be considered first in severe headache after the procedure. It should also be kept in mind that after all other secondary causes are excluded; SAH-like headaches after DSA can be detected

Obstetric hemorrhage: A global review.

Postpartum hemorrhage remains the number one cause of maternal death globally despite the fact that it is largely a preventable and most often a treatable condition. While the global problem is appreciated, some may not realize that in the United States postpartum hemorrhage is a leading cause of mortality and unfortunately, the incidence is on the rise. In New York, obstetric hemorrhage is the second leading cause of maternal mortality in the state. National data suggests that hemorrhage is disproportionally overrepresented as a contributor to severe maternal morbidity and we suspect as we explore further this will be true in New York State as well. Given the persistent and significant contribution to maternal mortality, it may be useful to analyze the persistence of this largely preventable cause of death within the framework of the historic "Three Delays" model of maternal mortality. The ongoing national and statewide problem with postpartum hemorrhage will be reviewed in this context of delays in an effort to inform potential solutions. Copyright © 2016 Elsevier Inc.

2014-01-01

BACKGROUND AND PURPOSE: Data on the incidence of stroke subtypes among ethnic minority groups are limited. We assessed ethnic differences in the incidence of stroke subtypes in the Netherlands. METHODS: A Dutch nationwide register-based cohort study (n=7 423 174) was conducted between 1998 and 2010....... We studied the following stroke subtypes: ischemic stroke, intracerebral hemorrhage, and subarachnoid hemorrhage. Cox proportional hazard models were used to estimate incidence differences between first-generation ethnic minorities and the Dutch majority population (ethnic Dutch). RESULTS: Compared.......16-0.72), and subarachnoid hemorrhage (0.42; 0.20-0.88 and 0.34; 0.17-0.68) compared with ethnic Dutch counterparts. The results varied by stroke subtype and sex for the other minority groups. For example, Turkish women had a reduced incidence of subarachnoid hemorrhage, whereas Turkish men had an increased incidence...

Cortical-sparing adrenalectomy is a suitable treatment for hereditary and sporadic bilateral pheochromocytoma, in cases of low risk of malignancy, to reduce the possibility of adrenal insufficiency assuming the chance of local recurrence. The aim of the study is to analyze the functional results of partial adrenalectomy by retroperitoneal endoscopic approach in single-adrenal patients or patients requiring bilateral adrenalectomy. Prospective study between January 2015 and February 2016 including pheochromocytoma patients diagnosed with low risk of malignant mutations. All patients agreed to be included in the study. Experienced endocrine surgeons who have been trained in minimally invasive endocrine surgery performed the procedure using the same surgical technique. Demographic variables and clinical characteristics were collected, subsequently carrying out the descriptive analysis of the data. A total of 6 patients were registered, four associated with MEN type 2 syndrome and two in the context of VHL syndrome. Retroperitoneoscopic resection was performed without laparoscopic or open conversion and no postoperative complications; the average hospital stay was 2.5 days. Preservation of the functional cortex without corticosteroids was achieved in 5 (83%) of out 6 cases with a follow-up of 26.2 ± 6 months. Today, these 5 patients have a preserved adrenal function without hormone replacement. Cortical-sparing adrenalectomy by the retroperitoneal endoscopic approach, in expert hands, is safe and feasible for the treatment of hereditary and sporadic pheochromocytoma in a context of low malignancy, making it possible to avoid the need for corticoid replacement in most cases.

2011-03-01

Liposarcoma (LS) is a rare and heterogeneous group of malignant mesenchymal neoplasms exhibiting characteristics of adipocytic differentiation. Currently, radical surgical resection represents the most effective and widely used therapy for patients with abdominal/retroperitoneal LS, but the presence of contiguous essential organs, such as the kidney, pancreas, spleen, adrenal glands, esophagus or colon, as well as often reoccurrence of LS in A/RP calls for the enhancement of surgical techniques to minimize resection and avoid LS reoccurrences. Difficulty in detecting the margins of neoplasms due to their affinity to healthy fat tissue accounts for the high reoccurrence of LS within A/RP. Nowadays, the microscopic detection of margins is possible only by use of biopsy, and the minimization of surgical resection of healthy tissues is challenging. In this presentation we'll demonstrate the initial OCT results for the imaging and distinction of LS and normal human fat tissues and clear detection of tumor boundaries.

The purpose of this study is to analyze the clinical impact of radical nephrectomy on retroperitoneal liposarcoma near the kidney. Data of patients who underwent surgery for unilateral primary retroperitoneal liposarcoma near the kidney were retrospectively collected. Patients were divided into four groups according to whether they underwent nephrectomy and combined resection of other organs. Kaplan-Meier survival analysis was used to estimate disease-free survival and overall survival. Multivariable Cox analysis was used to analyze factors related to disease-free survival and overall survival. Nephrectomy (HR = 0.260, CI = 0.078-0.873, p = 0.029) had a beneficial effect on disease-free survival, while interaction model of nephrectomy*other organ resection (HR = 4.655, CI = 1.767-12.263, p = 0.002) showed poor disease-free survival. Other organ resection was not related to disease-free survival (HR = 1.543, CI = 0.146-16.251, p = 0.718). Operation method (p = 0.007) and FNCLCC grade (p free survival. While combined organ resection without nephrectomy group (HR = 1.604, CI = 0.167-15.370, p = 0.682) and radical nephrectomy with combined organ resection group (HR = 1.309, CI = 0.448-3.825, p = 0.622) did not show significant difference in disease-free survival from the mass excision only group, radical nephrectomy without combined organ resection group (HR = 0.279, CI = 0.078-0.991, p = 0.048) showed superior disease-free survival. Radical nephrectomy of unilateral primary retroperitoneal liposarcoma near the kidney has a beneficial effect on disease-free survival.

Uchino, Akira; Ohnari, Norihiro; Ohno, Masato

1989-01-01

Six patients with acute hemorrhagic brain infarct were imaged using spin-echo (SE) pulse sequences on a 1.5 Tesla MR scanner. Including two patients with repeated MR imaging, a total of eight examinations, all performed within 15 days after stroke, were analyzed retrospectively. Four patients revealed massive hemorrhages in the basal ganglia or cerebellum and three cases demonstrated multiple linear hemorrhages in the cerebral cortex. On T1-weighted images, hemorrhages were either mildly or definitely hyperintense relative to gray matter, while varied from mildly hypointense to hyperintense on T2-weighted images. T1-weighted images were superior to T2-weighted images in detection of hemorrhgage. CT failed to detect hemorrhage in two of five cases: indicative of MR superiority to CT in the diagnosis of acute hemorrhagic infarcts. (author)

Unexpected visitor on FDG PET/CT--brown adipose tissue (BAT) in mesentery in a case of retroperitoneal extra-adrenal pheochromocytoma: is the BAT activation secondary to catecholamine-secreting pheochromocytoma?

Science.gov (United States)

Joshi, Prathamesh Vijay; Lele, Vikram Ramchandra

2012-05-01

Fused positron emission tomography-computed tomography (PET/CT) technology has enabled the determination that nonmalignant fluorodeoxyglucose (FDG) uptake is observed in brown adipose tissue (BAT). FDG uptake in BAT is a known potential source of false-positive interpretations for PET. The typical locations of BAT include neck, supraclavicular area, mediastinum, and paravertebral intercostal spaces. Examples of atypical locations for BAT include posterior neck, left paratracheal area, axillae, perirenal area, and retrocrural area. We report PET/CT findings in a young male patient with malignant retroperitoneal extra-adrenal pheochromocytoma, who demonstrated FDG uptake in BAT at multiple locations including mesenteric BAT. We also propose catecholamine-secreting pheochromocytoma as a possible cause of BAT activation in our case.

The purpose of this study is to identify the characteristics of brain perfusion measured by arterial spin-labeling magnetic resonance imaging (ASL-MRI) in cerebral hemorrhages. Brain blood flow values (CBF-ASL values) for cerebral and cerebellar hemispheres and segmented cerebral regions were measured by ASL-MRI in 19 putaminal hemorrhage patients and 20 thalamic hemorrhage patients in acute or subacute stages. We assessed the lateralities of CBF-ASL values and the relationships between CBF-ASL values and other imaging findings and clinical manifestations. Both the 19 putaminal hemorrhage patients and the 20 thalamic hemorrhage patients had significantly low CBF-ASL values of the contralateral cerebellum in subacute stage, suggesting that ASL-MRI might delineate crossed cerebellar diaschisis (CCD). Ipsilateral low CBF-ASL values were observed in frontal lobes and thalami with a putaminal hemorrhage and lentiform nuclei, temporal lobes, and parietal lobes with a thalamic hemorrhage, suggesting that ASL-MRI showed the ipsilateral cerebral diaschisis (ICD). In the putaminal hemorrhage patients, the hematoma volume negatively affected both the bilateral cerebellar and cerebral hemispheric CBF-ASL values. In the thalamic hemorrhage patients, a concomitant intraventricular hemorrhage caused low cerebral hemispheric CBF-ASL values. The use of ASL-MRI is sensitive to the perfusion abnormalities and could thus be helpful to estimate functional abnormalities in cerebral hemorrhage patients. (orig.)

Massive postpartum right renal hemorrhage.

Science.gov (United States)

Kiracofe, H L; Peterson, N

1975-06-01

All reported cases of massive postpartum right renal hemorrhage have involved healthy young primigravidas and blacks have predominated (4 of 7 women). Coagulopathies and underlying renal disease have been absent. Hematuria was painless in 5 of 8 cases. Hemorrhage began within 24 hours in 1 case, within 48 hours in 4 cases and 4 days post partum in 3 cases. Our first case is the only report in which hemorrhage has occurred in a primipara. Failure of closure or reopening of pyelovenous channels is suggested as the pathogenesis. The hemorrhage has been self-limiting, requiring no more than 1,500 cc whole blood replacement. Bleeding should stop spontaneously, and rapid renal pelvic clot lysis should follow with maintenance of adequate urine output and Foley catheter bladder decompression. To date surgical intervention has not been necessary.

Retroperitoneal extra-adrenal paraganglioma: a rare but important diagnosis.

LENUS (Irish Health Repository)

Ahmad, S

2012-01-31

BACKGROUND: Extra-adrenal paragangliomas of the retroperitonium are infrequently diagnosed. Their malignant behaviour cannot be predicted on initial clinical and histological assessment. These tumours have higher propensity for subsequent metastasis compared with pargangliomas at other sites. AIM: We aim to describe a case report of an incidental finding of left retroperitoneal paraganglioma in a young man who presented with right flank pain. We also aim to emphasize the importance of diagnosis and the malignant potential of these tumours. METHOD: Patient\\'s clinical notes, operative findings, imaging studies and laboratory investigations including histology results were reviewed. A literature search was done to look into the incidence, presentation, follow-up plan and treatment options for these tumours. CONCLUSION: Surgical resection is the only available curative option for extra-adrenal paragangliomas. Metastasis is observed years after surgery, hence long-term follow-up is required.

Hemorrhage Detection and Segmentation in Traumatic Pelvic Injuries

Automated hemorrhage detection and segmentation in traumatic pelvic injuries is vital for fast and accurate treatment decision making. Hemorrhage is the main cause of deaths in patients within first 24 hours after the injury. It is very time consuming for physicians to analyze all Computed Tomography (CT) images manually. As time is crucial in emergence medicine, analyzing medical images manually delays the decision-making process. Automated hemorrhage detection and segmentation can significantly help physicians to analyze these images and make fast and accurate decisions. Hemorrhage segmentation is a crucial step in the accurate diagnosis and treatment decision-making process. This paper presents a novel rule-based hemorrhage segmentation technique that utilizes pelvic anatomical information to segment hemorrhage accurately. An evaluation measure is used to quantify the accuracy of hemorrhage segmentation. The results show that the proposed method is able to segment hemorrhage very well, and the results are promising.

Between 1980 and 1994, 423 patients with esophageal cancer were given curative r[iation therapy. Of these patients, 31 died of massive hemorrhage and were used as the subjects of analysis in this study. The incidence of massive hemorrhage in all patients was 7% (31/423). In the 31 patients who died of massive hemorrhage, 27 h[ local tumors and two h[ no tumors at hemorrhage (two unknown cases). The mean time interval from the start of r[iation to hemorrhage was 9.2 months. In 9 autopsy cases the origin of hemorrhage was a tear of the aorta in 5 cases, necrotic local tumor in 3 cases and esophageal ulcer in 1 case. The positive risk factors for this complication seemed to be excess total dose, infection, metallic stent, and tracheoesophageal fistula. Chest pain or sentinel hemorrhage proceeding to massive hemorrhage was observed in about half of the patients. (orig.)

Matsuda, Hiroo; Inoue, Takao; Shimura, Kohji

1980-01-01

Clinical pigns, laboratory data, CT findings, CSF spectrophotometric findings and CSF/blood glucose ratio were reviewed on thirty six newborns with intracranial hemorrhage confirmed by CT and/or autopsy and the following findings were obtained. The sites of hemorrhage were: intraventricular 14, intracerebral 4, subdural 2, subarachnoidal 16. 1) Convulsion (39%), hypotonia (58%), apnea (47%), and bradycardia (58%) were seen, but those were not regarded as specific for the intracranial hemorrhage. 2) Severe anemia of hemoglobin value less than 14 g/dl (17%), more than 10% fall of hematocrit (10%), and hyperglycemia of blood glucose more than 200 mg/gl (42%) were seen almost equally in every type of hemorrhage. 3) On CSF spectrophotometry, ajj twelve cases of intraventricular and four cases of intracerebral hemorrhage had the oxyhemoglobin peak absorbance. However, of fourteen cases of subarachnoidal hemorrhage, three had the oxyhemoglobin peak absorbance but the other eleven cases had the bilirubin peak absorbance. 4) Hypoglycorrachia, defined as CSF/blood glucose ratio less than 0.4, was recognized only in the intraventricular hemorrhage group (5/9, 56%). It was concluded that lumbar puncture should be done first of all when intracranial hemorrhage is suspected. If hypoglycorrachia or oxyhemoglobin peak absorbance is recognized, computed tomography should be performed immediately to know the accurate site and extent of hemorrhage. Although hypoglycorrachia is more specific for the intraventricular hemorrhage, it is usually found several days after the hemorrhage. On the other hand, oxyhemoglobin can be identified in CSF within a day after the episode of hemorrhage and this method is more benifical for the early diagnosis. (author)

Mini-open lateral retroperitoneal lumbar spine approach using psoas muscle retraction technique. Technical report and initial results on six patients.

Science.gov (United States)

Aghayev, Kamran; Vrionis, Frank D

2013-09-01

The main aim of this paper was to report reproducible method of lumbar spine access via a lateral retroperitoneal route. The authors conducted a retrospective analysis of the technical aspects and clinical outcomes of six patients who underwent lateral multilevel retroperitoneal interbody fusion with psoas muscle retraction technique. The main goal was to develop a simple and reproducible technique to avoid injury to the lumbar plexus. Six patients were operated at 15 levels using psoas muscle retraction technique. All patients reported improvement in back pain and radiculopathy after the surgery. The only procedure-related transient complication was weakness and pain on hip flexion that resolved by the first follow-up visit. Psoas retraction technique is a reliable technique for lateral access to the lumbar spine and may avoid some of the complications related to traditional minimally invasive transpsoas approach.

1990-01-01

The posterior pararenal space(PPS) is a potential space between the posterior renal fascia and the transversalis fascia. We reviewed 12 cases of posterior pararenal effusion. The causes of the effusion were retroperitoneal hemorrhage due to trauma(7 cases) or rupture of renal tumor(1 case), pancreatitis(2 cases), urinoma (1 case) and amebic colitis of the cecum(1 case). The CT findings of the effusion were semilunar fluid density in the dependant portion of the PPS(9/12), partial obliteration of the PPS extending to the flank stripe(2/12), and total obliteration of the PPS extending to the anterior abdominal wall(1/12). The effusion in the ipsilateral perirenal space and thickening of the ipsilateral posterior renal fascia were combined in all cases. The effusion in the ipsilateral anterior pararenal space was associated in 11 cases of 12. The effusion in the PPS is not uncommon findings of retroperitoneal hemorrhage or effusion, but usually related with perirenal or anterior pararenal effusion with no clinical significance

Surgical management of spontaneous hypertensive brainstem hemorrhage

Directory of Open Access Journals (Sweden)

Bal Krishna Shrestha

2015-09-01

Full Text Available Spontaneous hypertensive brainstem hemorrhage is the spontaneous brainstem hemorrhage associated with long term hypertension but not having definite focal or objective lesion. It is a catastrophic event which has a poor prognosis and usually managed conservatively. It is not uncommon, especially in eastern Asian populations, accounting approximately for 10% of the intracerebral hemorrhage. Before the advent of computed tomography, the diagnosis of brainstem hemorrhage was usually based on the clinical picture or by autopsy and believed to be untreatable via surgery. The introduction of computed tomography permitted to categorize the subtypes of brainstem hemorrhage with more predicted outcome. Continuous ongoing developments in the stereotactic surgery and microsurgery have added more specific surgical management in these patients. However, whether to manage conservatively or promptly with surgical evacuation of hematoma is still a controversy. Studies have shown that an accurate prognostic assessment based on clinical and radiological features on admission is critical for establishing a reasonable therapeutic approach. Some authors have advocate conservative management, whereas others have suggested the efficacy of surgical treatment in brainstem hemorrhage. With the widening knowledge in microsurgical techniques as well as neuroimaging technology, there seems to have more optimistic hope of surgical management of spontaneous hypertensive brainstem hemorrhage for better prognosis. Here we present five cases of severe spontaneous hypertensive brainstem hemorrhage patients who had undergone surgery; and explore the possibilities of surgical management in patients with the spontaneous hypertensive brainstem hemorrhage.

Ten cases of primary brain tumor presenting as intracranial hemorrhage were studied in terms of the radiological and histological findings. The cases having hemorrhage in the tumor, as established through CT or histologically, were excluded if their onsets were not sudden due to intracranial hemorrhages. The results obtained may be summarized as follows: 1) From an anatomical point of view, cerebral subcortical hemorrhages account for 80%; hemorrhages in the cerebellopontine angle, 10%, and hemorrhages in the basal ganglia, 10%. 2) Plain CT findings showed perifocal low-density areas within 24 hours after onset in all 10 cases. 3) Enhanced CT findings showed enhanced areas in 4 or 6 cases. 4) Angiographic findings revealed abnormalities besides the mass effect in 5 of the 10 cases. 4) Angiographic findings revealed abnormalities besides the mass effect in 5 of the 10 cases. 5) From a histological point of view, glioblastomas account for 30%; malignant astrocytomas, 20%; astrocytomas, 20%; malignant ependymomas, 10%; hemangioblastoma, 10%, and transitional meningiomas, 10%. In conclusion, a perifocal low-density area on CT within 24 hours after onset is the most meaningful indication of intracranial hemorrhage originating from a brain tumor. A histological 'perinuclear halo' in an astrocytoma as an artifact due to hemorrhage may often be misleading in diagnosing mixed oligo-astrocytomas. (author)

Ebola hemorrhagic fever is an often-fatal disease caused by a virus of the Filoviridae family, genus Ebolavirus. Initial signs and symptoms of the disease are nonspecific, often progressing on to a severe hemorrhagic illness. Special Operations Forces Medical Providers should be aware of this disease, which occurs in sporadic outbreaks throughout Africa. Treatment at the present time is mainly supportive. Special care should be taken to prevent contact with bodily fluids of those infected, which can transmit the virus to caregivers. 2014.

Functional recovery and surgical indication in putaminal hemorrhage

International Nuclear Information System (INIS)

Fujitsu, Kazuhiko

1983-01-01

Forty-one cases of varied sized putaminal hemorrhage were classified into 4 types according to the precise localization on CT (Fig. 1). All cases with large-sized hemorrhage (more than 4-5 cm in the actual diameter) were treated surgically regardless of their types in CT classification. ADL was assessed 6 months after the onset in all 41 cases, and in 17 of these Standard Language Test of Aphasia (SLTA) was also given 1 to 3 months after the dominant hemispheric hemorrhage. Type I hemorrhage usually showed excellent ADL independently of the size of the hemorrhage (Table 3). In type II hemorrhage, the ADL is determined by the extent of the lesion and tended to deteriorate as the size of the hemorrhage increased (Table 4). Type III hemorrhage resumed less favorable ADL than the type II did (Table 5), and there was scarcely any functional recovery in Type IV hemorrhage (Table 6). On SLTA, impairment of the speaking ability was the prominant feature when the hemorrhage was primarily located in the anterior portion of the insula, while the hearing ability was more markedly impaired in the posteriorly located lesion. These location-dependent specific patterns of impairment on SLTA are schematically presented in Fig. 12. From these results described above, the author's CT classification is considered to be very useful not only in forecasting the prospects of functional recovery, but in determining the surgical indication in putaminal hemorrhage.

2013-09-01

To analyze retrospectively cause, prevention and management of postoperative hemorrhage in surgery of obstructive sleep apnea hypopnea syndrome (OSAHS) in children using plasma-mediated radio-frequency (pmRF) ablation at low temperature. Tonsil and adenoid ablation were carried out in 4028 cases diagnosed with OSAHS, using ENTColator lI plasma system of Arthocare company under general anesthesia. Postoperative hemorrhage occurred in 37 cases of 4028 cases, among which 1 case occurred after tonsil ablation and other 36 cases occurred after adenoid ablation. Primary hemorrhage was in 7 cases, while secondary hemorrhage in other 30 cases. Cessation of bleeding was achieved by using different methods of hemostasis in all cases. Tonsil and adenoid ablation were performed by pmRF at low temperature with advantages of less trauma, less bleeding. However, postoperative hemorrhage might occur in a few cases (accounting for 0.92%). Postoperative hemorrhage in these patients was related with preoperatively incomplete control of inflammation of tonsil or adenoid, surgeon's experience, intraoperatively incomplete hemostasis, postoperative crying and restlessness, eating improperly in two weeks after surgery, coagulation factor deficiency. In case of postoperative hemorrhage, good outcome could be achieved by management of compression, pmRF at low temperature, bipolar coagulation.

Full Text Available Objective: The aim of this study was to identify predictors of viable germ cell tumor (GCT in postchemotherapeutic residual retroperitoneal masses. Materials and Methods: The pertinent clinical and pathologic data of 16 male patients who underwent postchemotherapeutic retroperitoneal lymph node dissection (PC-RPLND at King Faisal Specialist Hospital and Research Centre between 1994 and 2005 were reviewed retrospectively. It was found that all patients received cisplatin-based chemotherapy for advanced testicular GCT. Results: Out of the 16 male patients, 2 (13%, 8 (50%, and 6 (37% had viable GCT, fibrosis, and teratoma, respectively. Ten (10 of the patients with prechemotherapeutic S1 tumor markers did not have viable GCT, and two of the six patients who had prechemotherapeutic S2 tumor markers have viable GCT. All tumor marker levels normalized after chemotherapy even in patients with viable GCT. Four patients had vascular invasion without viable GCT. Furthermore, four patients had more than 60% embryonal elements in the original pathology, but only 1 had viable GCT at PC-RPLND. Four of the five patients with immature teratoma had teratoma at PC-RPLND but no viable GCT; however, out of the four patients with mature teratoma, one had viable GCT and two had teratoma at PC-RPLND. Of the two patients with viable GCT, one had 100% embryonal cancer in the original pathology, prechemotherapeutic S2 tumor markers, history of orchiopexy, and no vascular invasion; the other patient had yolk sac tumor with 25% embryonal elements and 40% teratoma in the original pathology, and prechemotherapeutic S2 tumor markers. Conclusion: None of the clinical or pathological parameters showed a strong correlation with the presence of viable GCT in PC-RPLND. However, patients with ≥S2 may be at higher risk to have viable GCT. Further studies are needed to clarify this.

BACKGROUND AND PURPOSE: More than 50% of patients with acute intracerebral hemorrhage (ICH) are taking antihypertensive drugs before ictus. Although antihypertensive therapy should be given long term for secondary prevention, whether to continue or stop such treatment during the acute phase of ICH...... remains unclear, a question that was addressed in the Efficacy of Nitric Oxide in Stroke (ENOS) trial. METHODS: ENOS was an international multicenter, prospective, randomized, blinded endpoint trial. Among 629 patients with ICH and systolic blood pressure between 140 and 220 mmHg, 246 patients who were...... taking antihypertensive drugs were assigned to continue (n = 119) or to stop (n = 127) taking drugs temporarily for 7 days. The primary outcome was the modified Rankin Score at 90 days. Secondary outcomes included death, length of stay in hospital, discharge destination, activities of daily living, mood...

Vocal fold hemorrhage is an acute phonotraumatic injury treated with voice rest; recurrence is a generally accepted indication for surgical intervention. This study aims to identify factors predictive of recurrence based on outcomes of a large clinical series. Retrospective cohort. Retrospective review of cases of vocal fold hemorrhage presenting to a university laryngology service. Demographic information was compiled. Videostroboscopic exams were evaluated for hemorrhage extent, presence of varix, mucosal lesion, and/or vocal fold paresis. Vocal fold hemorrhage recurrence was the main outcome measure. Follow-up telephone survey was used to complement clinical data. Forty-seven instances of vocal fold hemorrhage were evaluated (25M:22F; 32 professional voice users). Twelve of the 47 (26%) patients experienced recurrence. Only the presence of varix demonstrated significant association with recurrence (P = 0.0089) on multivariate logistic regression. Vocal fold hemorrhage recurred in approximately 26% of patients. Varix was a predictor of recurrence, with 48% of those with varix experiencing recurrence. Monitoring, behavioral management and/or surgical intervention may be indicated to treat patients with such characteristics. © 2013 The American Laryngological, Rhinological and Otological Society, Inc.

CT scan is recognized to be a rapid, noninvasive and informative examination in evaluation of the head injured patient. It is also possible to evaluate the presence of the intracerebral hematoma without remarkable mass effect, cerebral contusion, associated cerebral edema and ventricular hemorrhage. We present a case of traumatic intraventricular hemorrhage. The patient was a 40-year-old male admitted to our hospital in a drowsy state following a fall from about one meter high. Craniogram showed a linear fracture in the left parietotemporal regions. In the CT scan, intraventricular hemorrhage associated with subarachnoid hemorrhage without intracerebral hematoma was shown. A symmetrical moderate dilatation of both lateral ventricles was also shown. Cerebral angiography revealed no abnormality. His condition deteriorated progressively, so ventricular drainage was performed, but he expired 5 days later. Considering this case, the mechanisms of pure intraventricular hemorrhage following head injury were discussed. (author)

A case of idiopathic omental hemorrhage

Full Text Available With the exception of trauma, intraperitoneal hemorrhage in young women is caused by the high frequency of ectopic pregnancy and ovarian bleeding. Here, we describe a case of idiopathic omental hemorrhage, which is a rare cause of intraperitoneal hemorrhage. Intraperitoneal hemorrhage was suspected in a 38-year-old Japanese woman based on contrast-enhanced computed tomography. Her last menstrual period was 23 days prior, and ovarian bleeding was considered based on bloody ascites revealed by culdocentesis. She underwent emergency surgery for hypovolemic shock. Although both ovaries were of normal size and no abnormal findings were observed, we performed a partial omentectomy because multiple clots were attached only to the greater omentum. Postoperatively, no rebleeding occurred, and she was discharged 11 days after the surgery. Because she did not have a clear history of trauma and underlying disease, idiopathic omental hemorrhage was diagnosed.

Background. Ischemic and hemorrhagic strokes have different pathophysiologies and possibly different long-term cerebral and functional implications. Hemorrhagic strokes expose the brain to irritating effects of blood and ischemic strokes reflect localized or diffuse cerebral vascular pathology. Methods. Participants were individuals who suffered either an ischemic (n = 172) or hemorrhagic stroke (n = 112) within the past six months and were involved in a postacute neurorehabilitation program....

To establish risk of hemorrhage in patients with varices compared to those without, determine additional risk factors, and make evidence-based treatment recommendations. Retrospective cohort study. Patients who were vocal performers presenting for care during a 24-month period were analyzed to determine incidence of hemorrhage. Patients with varices were compared to those without. Demographic information and examination findings (presence, location, character, and size of varices; presence of mucosal lesions or paresis) were analyzed to determine predictors of hemorrhage. A total of 513 patients (60.4% female, mean age 36.6 years ± 13.95 years) were evaluated; 14 patients presenting with hemorrhage were excluded. One hundred and twelve (22.4%) patients had varices; 387 (77.6%) did not. The rate of hemorrhage in patients with varices was 2.68% at 12 months compared to 0.8% in patients without. Cox proportional hazard regression analysis revealed a hazard ratio of 10.1 for patients with varix developing hemorrhage compared to nonvarix patients (P hemorrhage was 3.3 cases per 1,000 person-months for varix patients compared to 0.5 cases per 1,000 person-months in the nonvarix group. There was no significant difference in the incidence of paresis, mucosal lesions, location of varix (left or right side; medial or lateral), or varix morphology (pinpoint, linear, lake) between patients who hemorrhaged and those that did not. The presence of varices increases the risk of hemorrhage. Varix patients had 10 times the rate of hemorrhage compared to nonvarix patients, although the overall incidence is low. This data may be used to inform treatment of patients with varices. 4. Laryngoscope, 126:1163-1168, 2016. © 2015 The American Laryngological, Rhinological and Otological Society, Inc.

Medulla Oblongata Hemorrhage and Reverse Takotsubo Cardiomyopathy.

Science.gov (United States)

Gobeske, Kevin T; Sarano, Maurice E; Fugate, Jennifer E; Wijdicks, Eelco F

2017-12-19

Acute brain injury with strong surges of adrenergic outflow has resulted in takotsubo cardiomyopathy, but there are surprisingly few reports of takotsubo cardiomyopathy after intracranial hemorrhage, and none have been described from hemorrhage within the brainstem. We describe a patient with reverse and reversible cardiomyopathy following a hemorrhage in the lateral medulla oblongata. While it is limited in size, the location of the hemorrhage caused acute systolic failure with left ventricular ejection fraction of 27% and vasopressor requirement for cardiogenic shock and pulmonary edema. There was full recovery after 7 days. Detailed case report. Hemorrhage into medulla oblongata pressor centers may result in acute, reversible, stress-induced cardiomyopathy, affirming the adrenergic origin of this condition.

Neck and scleral hemorrhage in drowning.

Alexander, Russell T; Jentzen, Jeffrey M

2011-03-01

The determination of the cause and manner of death for a body recovered from the water can be difficult because of a lack of autopsy findings specific for drowning. This case report describes a 30-year-old man found submerged at the bottom of a hotel pool. An autopsy revealed scleral hemorrhages and fascial hemorrhages of multiple muscles of the anterior and posterior neck bilaterally. No evidence of traumatic injury was on the surface of the body. An investigation by law enforcement found no evidence of foul play. The occurrence of petechial and neck hemorrhage in a body recovered from the water is controversial, and a review of this literature will be given. We suggest that fascial hemorrhages of the muscles of the neck, as well as cephalic hemorrhages, can be explained by drowning-related elevated central venous pressure that is communicated to the head through the valveless veins of the neck. © 2010 American Academy of Forensic Sciences.

Relationship between hypertensive cerebral hemorrhage and ischemic lesions

Yamaguchi, Shinya; Tsuchiya, Takashi; Yamaguchi, Takenori

1991-01-01

Patchy parenchymal lesions of increased intensity were frequently identified in patients with cerebral hemorrhage in T2-weighted image of high-fields MR imaging. We studied 64 patients with brain hemorrhage to determine the frequency and distribution of those lesions. We defined an area with high intensity in T2 weighted and low or iso-intensity area in T1 weighted images smaller than 1.5 cm in diameter to be 'ischemic lesion'. Ishemic lesions were found in 48 (75%) of all cases; in 25 (75%) of 32 patients with putaminal hemorrhage, in 15 (100%) of 15 with thalamic hemorrhage, in 3 (33%) of 9 with subcortical hemorrhage. Multiple ischemic lesions were more frequently seen in thalamic hemorrhage than in putaminal hemorrhage. Only 5 (10%) of 48 cases with associated ischemic lesions had a previous history related to those lesions. Multivariable regression analysis identified hypertension as the major predictor of the presence of ischemic lesions. Patients with brain hemorrhage frequently accompanied with incidental ischemic lesions, making it difficult to establish a guideline of blood pressure control for prevention of recurrent stroke.

2008-07-01

To estimate the frequency and volume of fetomaternal hemorrhage during external cephalic version for term breech singleton fetuses and to identify risk factors involved with this complication. A prospective observational study was performed including all patients undergoing a trial of external cephalic version for a breech presentation of at least 36 weeks of gestation between 1987 and 2001 in our center. A search for fetal erythrocytes using the standard Kleihauer-Betke test was obtained before and after each external cephalic version. The frequency and volume of fetomaternal hemorrhage were calculated. Putative risk factors for fetomaternal hemorrhage were evaluated by chi(2) test and Mann-Whitney U test. A Kleihauer-Betke test result was available before and after 1,311 trials of external cephalic version. The Kleihauer-Betke test was positive in 67 (5.1%) before the procedure. Of the 1,244 women with a negative Kleihauer-Betke test before external cephalic version, 30 (2.4%) had a positive Kleihauer-Betke test after the procedure. Ten (0.8%) had an estimated fetomaternal hemorrhage greater than 1 mL, and one (0.08%) had an estimated fetomaternal hemorrhage greater than 30 mL. The risk of fetomaternal hemorrhage was not influenced by parity, gestational age, body mass index, number of attempts at version, placental location, or amniotic fluid index. The risk of detectable fetomaternal hemorrhage during external cephalic version was 2.4%, with fetomaternal hemorrhage more than 30 mL in less than 0.1% of cases. These data suggest that the performance of a Kleihauer-Betke test is unwarranted in uneventful external cephalic version and that in Rh-negative women, no further Rh immune globulin is necessary other than the routine 300-microgram dose at 28 weeks of gestation and postpartum.

We studied MR fluid attenuated inversion recovery (FLAIR) pulse sequences in 37 cases with subarachnoid hemorrhage caused by aneurysmal rupture. FLAIR sequence suppressed the CSF signal and produced very heavy T{sub 2} weighted images. Subarachnoid hemorrhage was able to be demonstrated as high signal intensity on FLAIR sequences in all patients clear visualization of acute subarachnoid hemorrhage was able to be obtained by MR FLAIR sequences in not only Fisher`s group 3 or 4, but also Fisher`s group 2. Moreover it was suited for the detection of intraaxial hematoma, Sylvian hematoma, subdural hematoma and subarachnoid hemorrhage in the posterior fossa and interhemispheric fissure. Especially, it was useful for detecting intraventricular hemorrhage. Therefore, if patients suffering from subarachnoid hemorrhage present slight headache or atypical symptoms, sometimes it may be more suitable to perform MRI FLAIR pulse sequences first. Aneurysms were found in 21 cases (56.8%). When the aneurysmal size is more than 7 mm, the rate of detection becomes 100%. Aneurysms present various MR appearances because of flow characteristics. Aneurysms were demonstrated as low signal intensity except in 3 cases. In one out of 3 cases, aneurysms were revealed as high signal intensity and in the other two cases, it was revealed as mixed signal intensity. According to the previous studies, rapid flow was demonstrated as low signal intensity by vascular flow void, and delayed flow was demonstrated as high or mixed signal intensity by flow related enhancement and even echo rephasing. MR clearly delineates the size, the lumen, the flow, and the extraaxial location of aneurysms. (K.H.)

Compared to vaginal delivery, women undergoing cesarean delivery are at increased risk of postpartum hemorrhage. Management approaches may differ between those undergoing prelabor cesarean delivery compared to intrapartum cesarean delivery. We examined surgical interventions, blood component use, and maternal outcomes among those experiencing severe postpartum hemorrhage within the two distinct cesarean delivery cohorts. We performed secondary analyses of data from two cohorts who underwent prelabor cesarean delivery or intrapartum cesarean delivery at a tertiary obstetric center in the United States between 2002 and 2012. Severe postpartum hemorrhage was classified as an estimated blood loss ≥1500mL or receipt of a red blood cell transfusion up to 48h post-cesarean delivery. We examined blood component use, medical and surgical interventions and maternal outcomes. The prelabor cohort comprised 269 women and the intrapartum cohort comprised 278 women. In the prelabor cohort, one third of women received red blood cells intraoperatively or postoperatively, respectively. In the intrapartum cohort, 18% women received red blood cells intraoperatively vs. 44% postoperatively (Pcesarean delivery had the highest rates of morbidity, with 18% requiring hysterectomy and 16% requiring intensive care admission. Our findings provide a snapshot of contemporary transfusion and surgical practices for severe postpartum hemorrhage management during cesarean delivery. To determine optimal transfusion and management practices in this setting, large pragmatic studies are needed. Copyright © 2017 Elsevier Ltd. All rights reserved.

Purpose: In relapsing testicular cancer, additional chemotherapy is followed by abdominal CT. If residual lesions are found, retroperitoneal lymphadenectomy is considered. We studied retrospectively whether morphological criteria can help in selected cases in deciding about lymphadenectomy by distinguishing between vital tumor, scarring and mature teratoma. Methods: In 26 patients who had been treated by salvage chemotherapy and retroperitoneal lymphadenectomy for non-seminomatous testicular cancer between 1990 and 1997, abdominal computed tomography and histology were correlated. Results: Histological examination found scarring in 10 patients, vital tumor in 6, mature teratoma in 4, and simultaneous teratoma and vital tumor in 6. A single CT criterion for distinguishing between these histologies was not identified. In two patients with large masses which were partly cystic and partly solid vital tumor and teratoma were verified. Scarrings may be expected in cystic lesions at the level of the renal hilus which are lined by a thin and smooth wall. Size did not matter. Conclusion: Accurate differentiation between vital tumor and necrosis was not possible. Before lymphadenectomy CT, however, localised lesions. (orig.) [Deutsch] Ziel: Bei Patienten mit rezidivierten Hodentumoren wird nach erneuter Chemotherapie die abdominelle CT durchgefuehrt.

2013-01-01

Full Text Available Inconsistency of the current classification of cerebral intraventricular hemorrhages is discussed in the article. The author explains divergence of including of the subependymal (1st stage and intracerebral (4th stage hemorrhages into this classification. A new classification of cerebral intraventricular hemorrhages including their origin, phases and stages is offered. The most common origin of intraventricular hemorrhages is subependymal hemorrhage (82,2%. Two phases of hemorrhage were distinguished: bleeding phase and resorption phase. Stages of intraventricular hemorrhages reflecting the blood movement after the onset of bleeding are the following: 1 — infill of the up to ½ of the lateral ventricles without their enlargement; 2 — infill of more than ½ of the lateral ventricles with their enlargement; 3 — infill of the IV ventricle, of the cerebellomedullary cistern and its dislocation into the subarachnoid space of the cerebellum, pons varolii, medulla oblongata and spinal cord.

Impaired Fracture Healing after Hemorrhagic Shock

Directory of Open Access Journals (Sweden)

Philipp Lichte

2015-01-01

Full Text Available Impaired fracture healing can occur in severely injured patients with hemorrhagic shock due to decreased soft tissue perfusion after trauma. We investigated the effects of fracture healing in a standardized pressure controlled hemorrhagic shock model in mice, to test the hypothesis that bleeding is relevant in the bone healing response. Male C57/BL6 mice were subjected to a closed femoral shaft fracture stabilized by intramedullary nailing. One group was additionally subjected to pressure controlled hemorrhagic shock (HS, mean arterial pressure (MAP of 35 mmHg for 90 minutes. Serum cytokines (IL-6, KC, MCP-1, and TNF-α were analyzed 6 hours after shock. Fracture healing was assessed 21 days after fracture. Hemorrhagic shock is associated with a significant increase in serum inflammatory cytokines in the early phase. Histologic analysis demonstrated a significantly decreased number of osteoclasts, a decrease in bone quality, and more cartilage islands after hemorrhagic shock. μCT analysis showed a trend towards decreased bone tissue mineral density in the HS group. Mechanical testing revealed no difference in tensile failure. Our results suggest a delay in fracture healing after hemorrhagic shock. This may be due to significantly diminished osteoclast recruitment. The exact mechanisms should be studied further, particularly during earlier stages of fracture healing.

The concentration of the canceroembryonal antigen (CEA) has been determined in vitro by the radioimmunological analysis of the blood plasma of 70 donors and 130 patients with malignant tumours of the intestine (6 persons), stomach (77), with relapsing gastric carcinoma (12), tumours of the pancreas (7), retroperitoneal space (18) and with inflammatory disease of the gastrointestinal tract (12). It is established that the radioimmunological test in vitro for CEA can be used not only for primary diagnosis of cancer of the rectum but also as a substantial supplement to the clinical diagnosis of carcinoma of the stomach and the pancreas. A relationship revealed between the rise in the content of CEA and the extent of malignancy provides additional information for correct diagnosing the stage of gastric carcinoma and a choice of an adequate method of treatment. Tolerance of the CEA level in the blood in retroperitoneal tumours and inflammatory diseases of the gastrointestinal tract may serve as a criterion for differential diagnosis of malignant newgrowths in the abdominal cavity.

Intracerebral hemorrhage (ICH) resulting from the rupture of the blood vessels in the brain is associated with significantly higher mortality and morbidity. Clinical studies focused on alleviating the primary injury, hematoma formation and expansion, were largely ineffective, suggesting that secondary injury-induced inflammation and the formation of reactive species also contribute to the overall injury process. In this study, we explored the effects of cofilin knockdown in a mouse model of ICH. Animals given stereotaxic injections of cofilin siRNA, 72-h prior to induction of ICH by collagenase injection within the area of siRNA administration showed significantly decreased cofilin expression levels and lower hemorrhage volume and edema, and the animals performed significantly better in neurobehavioral tasks i.e., rotarod, grip strength and neurologic deficit scores. Cofilin siRNA knocked-down mice had reduced ICH-induced DNA fragmentation, blood-brain barrier disruption and microglial activation, with a concomitant increase in astrocyte activation. Increased expression of pro-survival proteins and decreased markers of oxidative stress were also observed in cofilin siRNA-treated mice possibly due to the reduced levels of cofilin. Our results suggest that cofilin plays a major role in ICH-induced secondary injury, and could become a potential therapeutic target. Copyright © 2018 IBRO. Published by Elsevier Ltd.

The clinical presentation of adrenal hemorrhage varies, depending on the extent of hemorrhage as well as the amount of adrenal cortex involved by the hemorrhage. We report here a case of neonatal adrenal hemorrhage revealed by late onset of neonatal jaundice. This adrenal hemorrhage most probably resulted from shoulder dystocia. The aim of this work was to focus on the fact that jaundice can be caused by adrenal hemorrhage and to emphasize the crucial importance of abdominal ultrasound in cases of persistent jaundice.

Purpose. To evaluate the efficacy and safety of endovascular therapy in oral hemorrhage from malignant head and neck tumors. Methods. Ten patients (mean age 56 years) with oral hemorrhage caused by malignant head and neck tumors underwent a total of 13 emergency embolization procedures using gelatin sponge particles, steel and/or platinum coils, or a combination of these embolic materials. Angiographic abnormalities, technical success rate, clinical success rate, recurrence rate, complications, hemostatic period, hospital days, survival days, and patient outcome were all analyzed. Results. Angiographic abnormalities were identified during 85% of procedures (11/13). The technical success rate was 100% (13/13 procedures). The primary and secondary clinical success rates were 77% (10/13 procedures) and 67% (2/3 procedures), respectively. The overall clinical success rate was 92%, and the recurrence rate was 22% (2/9 procedures) in patients whom we were able to observe during the 1-month period after embolization. No major complications occurred. Several patients in whom gelatin sponge particles had been used complained of transient local pain after the procedure. The median hemostatic period was 71 days (range 0-518 days). Median hospital and survival days were 59 days (range 3-209 days) and 141 days (range 4-518 days), respectively. Three patients survived and 7 patients died during the observation period. Only 1 of these 7 patients died from hemorrhage. Conclusion. In conclusion, our findings suggest that endovascular therapy is an effective, safe, and repeatable treatment for oral hemorrhage caused by malignant head and neck tumors

Dilated fundoscopic exam is considered the gold standard for detecting retinal hemorrhage, but expertise in obtaining this exam is not always immediately available. MRI can detect retinal hemorrhages, but correlation of the grade or severity of retinal hemorrhage on dilated fundoscopic exam with retinal hemorrhage visibility on MRI has not been described. To determine the value of standard brain protocol MRI in detecting retinal hemorrhage and to determine whether there is any correlation with MR detection of retinal hemorrhage and the dilated fundoscopic exam grade of hemorrhage. We conducted a retrospective chart review of 77 children <2 years old who were seen for head trauma from April 2007 to July 2013 and had both brain MRI and dilated fundoscopic exam or retinal camera images. A staff pediatric radiologist and radiology resident reviewed the MR images. Retinal hemorrhages were graded by a chief ophthalmology resident on a 12-point scale based on the retinal hemorrhage type, size, location and extent as seen on review of retinal camera images and detailed reports by ophthalmologists. Higher scores indicated increased severity of retinal hemorrhages. There was a statistically significant difference in the median grade of retinal hemorrhage examination between children who had retinal hemorrhage detected on MRI and children who did not have retinal hemorrhage detected on MRI (P = 0.02). When examination grade was categorized as low-grade (1-4), moderate-grade (5-8) or high-grade (>8) hemorrhage, there was a statistically significant association between exam grade and diagnosis based on MRI (P = 0.008). For example, only 14% of children with low-grade retinal hemorrhages were identified on MRI compared to 76% of children with high-grade hemorrhages. MR detection of retinal hemorrhage demonstrated a sensitivity of 61%, specificity of 100%, positive predictive value of 100% and negative predictive value of 63%. Retinal hemorrhage was best seen on the gradient

Determine the prevalence of intraventricular hemorrhage in infants with moderate to severe congenital heart disease, investigate the impact of gestational age, cardiac diagnosis, and cardiac intervention on intraventricular hemorrhage, and compare intraventricular hemorrhage rates in preterm infants with and without congenital heart disease. A single-center retrospective review. A tertiary care children's hospital. All infants admitted to St. Louis Children's Hospital from 2007 to 2012 with moderate to severe congenital heart disease requiring cardiac intervention in the first 90 days of life and all preterm infants without congenital heart disease or congenital anomalies/known genetic diagnoses admitted during the same time period. None. Cranial ultrasound data were reviewed for presence/severity of intraventricular hemorrhage. Head CT and brain MRI data were also reviewed in the congenital heart disease infants. Univariate analyses were undertaken to determine associations with intraventricular hemorrhage, and a final multivariate logistic regression model was performed. There were 339 infants with congenital heart disease who met inclusion criteria and 25.4% were born preterm. Intraventricular hemorrhage was identified on cranial ultrasound in 13.3% of infants, with the majority of intraventricular hemorrhage being low-grade (grade I/II). The incidence increased as gestational age decreased such that intraventricular hemorrhage was present in 8.7% of term infants, 19.2% of late preterm infants, 26.3% of moderately preterm infants, and 53.3% of very preterm infants. There was no difference in intraventricular hemorrhage rates between cardiac diagnoses. Additionally, the rate of intraventricular hemorrhage did not increase after cardiac intervention, with only three infants demonstrating new/worsening high-grade (grade III/IV) intraventricular hemorrhage after surgery. In a multivariate model, only gestational age at birth and African-American race were predictors

Ninety-two percent of 100 patients with putaminal hemorrhage were hypertensive. Of the eight normotensive patients, seven were substance abusers or had bilateral putaminal hemorrhages. The one other normotensive patient was less than 40 years old. The 100 hemorrhages had the following locations: 1. Medial putaminal (17 cases; six were normotensive and less than 40 years old and five were substance abusers); 2. lateral putaminal extending through the external capsule (eleven cases); 3. putaminal-capsular and subcortical white matter (32 cases); 4. putaminal cerebral hemispheric (19 cases); 5. putaminal-thalamic (19 cases); 6. bilateral (two cases). A disproportionate number of black patients suffered hematoma extension to the cerebral hemispheres or thalamus (46%) compared to Caucasians (23%). Overall mortality was 20% (17 blacks and three Caucasians) and occurred in patients with hematoma extension to the thalamus or cerebral hemispheres. Contrast-enhanced CT was performed in all 100 patients and provided no additional diagnostic yield. This indicates limited use for enhanced CT in hypertensive patients with putaminal hemorrhage who have a characteristic appearance of the acute hemorrhage on the nonenhanced CT. (orig.)

Full Text Available Dengue is a viral disease that is mediated by a mosquito, which causes morbidity and mortality. Viruses can increase vascular permeability which can lead to hemorrhagic diathesis or disseminated intravascular coagulation (DIC known as dengue hemorrhagic fever (DHF. In Indonesia, dengue hemorrhagic fever (DHF are caused by dengue virus infection which was found to be endemic accompanied by an explosion of extraordinary events that appear at various specified period. The diagnosis of dengue is determined based on the criteria of the World Health Organization (WHO, 1999, which are sudden high fever accompanied by a marked tendency to hemorrhage positive tourniquet test, petechiae, ecchymosis, purpura, mucosal hemorrhagic, hematemesis or melena and thrombocytopenia. The problem that still exists today is the mechanism of thrombocytopenia in patients with varying degrees of dengue involving levels of vWF (von Willebrand factor and prostaglandin I2 (PGI2 can not be explained. The mechanism of hemorrhagic in dengue virus infections acquired as a result of thrombocytopenia, platelet disfunction decreased coagulation factors, vasculopathy with endothelial injury and disseminated intravascular coagulation (DIC.

Biomechanical stress analysis has been used for plaque vulnerability assessment. The presence of plaque hemorrhage (PH) is a feature of plaque vulnerability and is associated with thromboembolic ischemic events. The purpose of the present study was to use finite element analysis (FEA) to compare the stress profiles of hemorrhagic and non-hemorrhagic profiles. Forty-five consecutive patients who had suffered a cerebrovascular ischemic event with an underlying carotid artery disease underwent high-resolution magnetic resonance imaging (MRI) of their symptomatic carotid artery in a 1.5-T MRI system. Axial images were manually segmented for various plaque components and used for FEA. Maximum critical stress (M-Cstress SL ) for each slice was determined. Within a plaque, the maximum M-Cstress SL for each slice of a plaque was selected to represent the maximum critical stress of that plaque (M-Cstress PL ) and used to compare hemorrhagic and non-hemorrhagic plaques. A total of 62% of plaques had hemorrhage. It was observed that plaques with hemorrhage had significantly higher stress (M-Cstress PL ) than plaques without PH (median [interquartile range]: 315kPa [247-434] vs. 200kPa [171-282], P=0.003). Hemorrhagic plaques have higher biomechanical stresses than non-hemorrhagic plaques. MRI-based FEA seems to have the potential to assess plaque vulnerability. (author)

Sena Esteves, Sara; Cardoso, Carla; Silva, Ana; Abrunhosa, José; Almeida E Sousa, Cecília

Hereditary hemorrhagic telangiectasia (HHT), also known by the eponym Osler-Weber-Rendu syndrome, is an autosomal dominant disorder characterised by the presence of multiple arteriovenous malformations (AVMs) affecting multiple organs. Many procedures have been used for epistaxis control in patients with this disorder. The objective of this study was to report the treatment of severe HHT-related epistaxiswith the modified Young's procedure. We describe the treatment of 4 patients with severe blood-transfusion-dependent epistaxis who underwent a modified Young's procedure in a tertiary hospital. The nasal closure was bilateral and complete in all cases. All patients were followed for 12 months or longer. The procedure was well tolerated and complete cessation of bleeding was achieved in all the patients. Young's technique is a safe surgical procedure, well tolerated by patients with severe epistaxis and HHT.

More than 300 NMR examinations form the basis of the survey presented of the anatomy and topography of the retroperitoneal space. The examinations were done with the Siemens supraconducting magnet system 'Magnetom' (1.0 Tesla), with different planes of imaging chosen, according to clinical approaches (axial, sagittal, frontal). Sectional thicknesses varied between 5 and 10 mm. The spin-echo technique was applied, with repetition times between 0.3 and 2.0s, echo times between 30 and 150 ms. In addition, special means such as high-resolution coils and respiratory gating were applied, and also a contrast medium (gadolinium-DTPA). The possibilities of imaging are explained, referring to the pancreas, kidneys, adrenal glands, lymph nodes, aorta abdominalis, and vena cava inferior. (orig./MG) [de

Due of paucity of studies on stress ulcer prophylaxis in intracerebral hemorrhage (ICH), we have evaluated the usefulness of ranitidine and sucralfate in preventing gastric hemorrhage (GH) in patients with ICH. In a hospital-based randomized placebo-controlled study, patients with CT-proven ICH within 7 days of ictus were randomized into ranitidine 50 mg i.v. eight hourly, sucralfate 1 g six hourly and placebo groups. Patients were conservatively managed. Primary endpoint was occurrence of GH within 15 days of ictus and secondary endpoint 1-month mortality. The mean age of the patients was 57.2 (range 25-90) years and 40 were females. There were 45 patients in ranitidine, 49 in sucralfate and 47 in placebo group. Demographic, clinical and radiological features were not significantly different in 3 groups. GH occurred in 11 (23.4%) patients in placebo, 5 (11.1%) in ranitidine and 7 (14.3%) in sucralfate group, which was not significant. Only one female had GH. There were 13 (27.7%) deaths in placebo, 5 (11.1%) in ranitidine and 12 (24.5%) in sucralfate group. Pneumonia occurred in placebo group in 5 (10.6%), ranitidine in 2 (4.4%) and sucralfate in 5 (10.2%) patients, which was not significantly different. Ranitidine and sucralfate do not seem to significantly prevent GH or reduce 1-month mortality.

Full Text Available Purpose: The purpose of this study was to evaluate the treatment efficacy of vitrectomy combined with subretinal recombinant tissue plasminogen activator (r-tPA and factors affecting visual improvement in patients with submacular hemorrhage (SMH due to neovascular age-related macular degeneration (nAMD. Materials and Methods: Medical records of 17 consecutive patients diagnosed with SMH secondary to nAMD were retrospectively reviewed. The initial surgical procedure involved a 23-gauge transconjunctival vitrectomy, subretinal r-tPA application through a self-sealing inferior retinotomy, and sulfur hexafluoride gas for tamponade in all patients. The duration, size, and thickness of the hemorrhage and the pre- and post-operative visual acuity (VA using a Snellen chart were recorded. VA was converted to logMAR for statistical analysis. Results: The average duration and size of the SMH were 12.8 ± 18.2 days and 8.6 ± 5.3 disc areas, respectively. The mean follow-up time was 16.9 ± 4.7 months. A statistically significant visual improvement was found when comparing initial VA with postoperative best-corrected VA (BCVA and final BCVA (Wilcoxon rank test, P ≤ 0.01. There was no significant correlation between the size of the hemorrhage and postoperative BCVA and final BCVA (Spearman's rho test. There was no statistically significant correlation between the initial VA and postoperative BCVA and final BCVA (Spearman's rho test. There was no significant correlation between the duration of hemorrhage and postoperative BCVA and final BCVA (Spearman's rho test. The preoperative thickness of hemorrhage (747.5 ± 30 μm was not correlated with postoperative BCVA or final BCVA (Pearson's test. Conclusions: Vitrectomy combined with subretinal r-tPA injection and gas tamponade is an effective surgical intervention to preserve VA in selected patients with apparent SMH.

Intraventricular hemorrhage with cerebrovascular disease was identified in 81 cases and death occurred within seven days in 34 cases. Hypertension was the most common etiological factor, accounting for 40 of the 81 cases. Cerebral aneurysm was the second most common cause accounting for 27 cases, arteriovenous malformation accounted for 9 of the cases, and 5 were of other causes. Signs of primary or secondary brain stem dysfunction were mainly seen in cases with hypertension and aneurysm, while cases with arteriovenous malformation had benign courses. The mortality depended on the severity of intraventricular hemorrhage; i.e., the distribution, site, and the number of cast formation. The presence of intraventricular clot in the third and/or fourth ventricles was correlated with a high mortality rate, especially in cases accompanied by cast formation and third and fourth ventricular dilatation, which affects hypothalamus and brain stem function. Analysis of CT findings for the mechanism of intraventricular hemorrhage revealed three types: extension type, in which massive intracerebral hematomas extended and ruptured into ventricles; the direct type, which bled directly into ventricles without forming definite intracerebral hematomas; and the reflux type, which was characterized by reflux of the subarachnoid blood.

Five (9.6%) of 52 cases of supretentorial hypertensive intracerebral hemorrhage which suffered rehemorrhage in the contralateral regions were analyzed in the present study, and the 28 cases reported since 1950 were reviewed. The literature suggests that the time between the first hemorrhage and the second was quite long. However, the present series showed that re-hemorrhage in the contralateral side developed within one month in three out of five cases. In case 1, hemorrhages developed almost simultaneously in the left thalamus and in the right putamen. Three characteristics were observed: The symptoms including hemiparesis and/or hemispheric signs related to the first hemorrhage had a tendency to exacerbate after the second attack in other the contralateral region in the second attack, symptoms excessively severe for the size of the hematoma developed. Finally, the clinical course after the second hemorrhage was poor. (author)

Heterologous secondary infections are at increased risk of developing dengue hemorrhagic fever (DHF) because of antibody-dependent enhancement (ADE). IgG subclasses can fix and activate complement and bind to Fcɣ receptors. These factors may also play an important role in the development of ADE and thus in the pathogenesis of DHF. The aim of this study was to analyze the indices of anti-dengue IgG subclasses in adult patients with febrile and hemorrhagic dengue in the acute phase. In 2013, 129 patients with dengue fever (DF) and 57 with DHF in Veracruz, Mexico were recruited for this study and anti-dengue IgM and IgG determined by capture ELISA. Anti-dengue IgG subclasses were detected by indirect ELISA. Anti-dengue IgG2 and IgG3 subclasses were detected in patients with dengue. IgG1 increased significantly in the sera of patients with both primary and secondary infections and DHF, but was higher in patients with secondary infections. The IgG4 subclass index was significantly higher in the sera of patients with DHF than in that of those with DF, who were in the early and late acute phase of both primary and secondary infection. In conclusion, indices of subclasses IgG1 and IgG4 were higher in patients with DHF. © 2017 The Societies and John Wiley & Sons Australia, Ltd.

To review the feasibility of introducing advanced retroperitoneal renal laparoscopic surgery (RRLS) to a paediatric urology division, using the mentorship-training model. Although the scope of practice in paediatric urology is currently adapting endoscopic surgery into daily practice, most paediatric urologists in North America have had no formal training in laparoscopic surgery. The study included four paediatric urologists with 3-25 years of practice; none had had any formal laparoscopic training or ever undertaken advanced RRLS. An experienced laparoscopic surgeon (the mentor) assisted the learning surgeons over a year. The initial phases of learning incorporated detailed lectures, visualization through videotapes and 'hands-on' demonstration by the expert in the technique of the standardized steps for each type of surgery. Over 10 months, ablative and reconstructive RRLS was undertaken jointly by the surgeons and the mentor. After this training the surgeons operated independently. To prevent lengthy operations, conversion to open surgery was planned if there was no significant progression after 2 h of laparoscopic surgery. Over the 10 months of mentorship, 36 RRLS procedures were undertaken in 31 patients (28 ablative and eight reconstructive). In all cases the mentored surgeons accomplished both retroperitoneal access and the creation of a working space within the cavity. The group was able to initiate ablative RRLS but the mentor undertook all the reconstructive procedures. After the mentorship period, over 10 months, 12 ablative procedures were undertaken independently, and five other attempts at RRLS failed. Although the mentored approach can successfully and safely initiate advanced RRLS in a paediatric urology division, assessing the laparoscopic practice pattern after mentorship in the same group of trainees is warranted. Ablative RRLS is easier to learn for the experienced surgeon, but reconstructive procedures, e.g. pyeloplasty, require a high degree

Purpose. To evaluate the efficacy of embolotherapy using microcatheters in patients with hemorrhage from various locations. Methods. Among 29 patients there were 13 with severe epistaxis, 7 with gastrointestinal bleeding, 4 with hemorrhage in the kidney, 4 with bleeding in pelvic organs and 1 with bleeding in the shoulder region. In all cases, a Tracker-18 or Tracker-10 microcatheter was advanced coaxially through a 4.1 Fr guiding catheter in order to reach the bleeding site as distally as possible. Polyvinyl alcohol microparticles and/or platinum microcoils were used as embolic material. Results. The bleeding was stopped in 90% (26 of 29) of cases. In 66% of cases the treatment was curative, in 7% preoperative, and in 17% palliative. There were 3 clinical failures. Conclusion. Microcatheter embolization is an effective and safe means of managing different kinds of hemorrhage of various causes from a variety of sites

Purpose To determine if 3-T magnetic resonance (MR) neurography-guided retroperitoneal genitofemoral nerve (GFN) blocks are safe and effective for the diagnosis of genitofemoral neuralgia. Materials and Methods Following institutional review board approval and informed consent, 26 subjects (16 men, 10 women; mean age, 42 years [range, 24-78 years]; mean body mass index, 28 kg/m 2 [range, 20-35 kg/m 2 ]) with intractable groin pain were included. By using a 3-T MR imaging system, intermediate-weighted turbo spin-echo pulse sequences, and MR-conditional needles, diagnostic MR neurography-guided GFN blocks were performed in the retroperitoneum. Outcome variables included technical success, procedure time, complications, and rates of positive and negative GFN blocks in association with therapeutic outcomes. For the assessment of a learning curve, Mann-Whitney test was used. P values ≤ .05 were considered to indicate a statistically significant difference. Results In 26 subjects, 30 retroperitoneal GFN blocks were performed. Twelve (40%) were performed with an anterior needle path, 12 (40%) with a lateral needle path, and six (20%) with a posterior needle path. GFN blocks were technically successful in 24 of 26 (92%) subjects, achieving appropriate scrotal anesthesia. No complications occurred. The time required for a GFN block was 40 minutes (range, 18-67 minutes). The rate of a successful GFN intervention after a positive GFN block was 88% (14 of 16). The rate of a successful intervention of an alternative target after a negative GFN block was 71% (five of seven). Conclusion Selective retroperitoneally directed MR neurography-guided GFN blocks are safe and effective with high technical success and positive effect on surgical decision making in patients with presumed genitofemoral neuralgia. © RSNA, 2017 Online supplemental material is available for this article.

How Hemorrhage Control Became Common Sense.

Science.gov (United States)

Hawk, Alan James

2018-02-27

Just over 200 years ago, surgeons were puzzled that the use of the tourniquet to control hemorrhage as common sense during surgery was a relatively recent development. Within the last 20 years, much progress has been made to controlling hemorrhage in the prehospital context. Then, as now, it was surprising that progress on something that appeared obvious had occurred only recently, begging the question how controlling blood loss was common sense in a surgical context, but not for emergency treatment. Paper is a historical survey of the evolution of the medical understanding of hemorrhage along with technological response. The danger of blood loss had historically been consistently underestimated as physicians looked at other explanations for symptoms of how the human body responded to trauma. As the danger from hemorrhage became apparent, even obvious, responsibility for hemorrhage control was delegated down from the surgeon to the paramedic and eventually to individual service members and civilian bystanders with training to "Stop the Bleed." Hippocratic medicine assumed that blood diffused centrifugally into periphery through arteries. William Harvey's observation in 1615 that blood ran through a closed circulatory system gradually transformed conventional wisdom about blood loss, leading to the development of the tourniquet about a century later by Jean-Louis Petit, which made amputation of limbs survivable. However, physicians were cautious about their application during the First World War over concerns over effects on patient recovery. Hemorrhage had generally been seen as symptom to be managed until the patient would be seen by a surgeon who would stop the bleeding. More thorough collection and analysis of data related to case histories of soldiers wounded during the Vietnam Conflict transformed how surgeons understood the importance to hemorrhage leading to development of the doctrine of Tactical Combat Casualty Care in the late 1990's. economic

Shoulder dystocia and postpartum hemorrhage represent two of the most common emergencies faced in obstetric clinical practice, both requiring prompt recognition and management to avoid significant morbidity or mortality. Shoulder dystocia is an uncommon, unpredictable, and unpreventable obstetric emergency and can be managed with appropriate intervention. Postpartum hemorrhage occurs more commonly and carries significant risk of maternal morbidity. Institutional protocols and algorithms for the prevention and management of shoulder dystocia and postpartum hemorrhage have become mainstays for clinicians. The goal of this review is to summarize the diagnosis, incidence, risk factors, and management of shoulder dystocia and postpartum hemorrhage. Copyright © 2017 Elsevier Inc. All rights reserved.

The Roles of Thrombospondins in Hemorrhagic Stroke

Directory of Open Access Journals (Sweden)

Xuan Wu

2017-01-01

Full Text Available Hemorrhagic stroke is a devastating cerebrovascular disease with significant morbidity and mortality worldwide. Thrombospondins (TSPs, as matricellular proteins, belong to the TSP family which is comprised of five members. All TSPs modulate a variety of cellular functions by binding to various receptors. Recently, TSPs gained attention in the area of hemorrhagic stroke, especially TSP-1. TSP-1 participates in angiogenesis, the inflammatory response, apoptosis, and fibrosis after hemorrhagic stroke through binding to various molecules including but not limited to CD36, CD47, and TGF-β. In this review, we will discuss the roles of TSPs in hemorrhagic stroke and focus primarily on TSP-1.

We describe a hemorrhagic chondroid chordoma involving the sella turcica with suprasellar extension. The CT and MRI appearances mimiked a hemorrhagic pituitary adenoma. Chondroid chordoma is a variant composed of elements of both chordoma and cartilaginous tissue.

Prior to the introduction of computed tomography, the clinical and radiological diagnosis of the intraventricular hemorrhage in living patients was difficult. C.T. scanning is an invaluable investigation providing the rapid and noninvasive diagnosis of intracerebral and intraventricular hemorrhage. It reliably demonstrates the presence and distribution of fresh blood within the ventricular system. C.T. is also useful as a surgical guidance and in the evaluation of fate of the hematoma by easily performable follow-up studies. We reviewed 31 cases of intraventricular hemorrhage in C.T. in the department of radiology of Ewha Womans University Hospital during the period from August, 1982 to August, 1983. The results were as follows: 1. The most patients were encountered in the 5th decade and the male to female ratio was 1.2 : 1. 2. Hypertension was the main cause of the intraventricular hemorrhage; 18 out of 31 patients. Remaining 13 patients were caused by hypoxia, aneurysm, Moya Moya disease, coagulation defect, trauma and undetermined etiology. 3. 18 out of 31 patients showed hemorrhage in the lateral ventricles only and all ventricles in 10 patients. 4. 28 out of 31 patients showed associated with intracranial hematoma; Those were intracerebral hematomas in 16 patients, intracerebral hematoma with subarachnoid hemorrhage in 4 patients and extracerebral hematoma in 2 patients. 5. Outcome was assessed using the Glasgow scale. According to them, the total mortality rates was 54.8%, however, 32.3% of patients returned to normal or minor disability. Patients, who had hypertension and marked degree of hemorrhage in the ventricular systems had a poor outcome. Patients with only ventricular hemorrhage had better outcome than associated intracranial hematoma. 6. 16 out of 31 patients were treated by surgical methods and 15 out of 31 patients by conservative methods. 75% of patients were died in conservative treatment. 7. Conclusively, causes, degree of intraventricular

To report the birth prevalence, risk factors, characteristics, and location of fundus hemorrhages (FHs) of the retina and optic nerve present in newborns at birth. Prospective cohort study at Stanford University School of Medicine. All infants who were 37 weeks postmenstrual age or older and stable were eligible for screening. Infants with known or suspected infectious conjunctivitis were excluded. Infants born at Lucile Packard Children's Hospital (LPCH) from July 25, 2013, through July 25, 2014, were offered universal newborn screening via wide-angle digital retinal photography in the Newborn Eye Screen Test study. Maternal, obstetric, and neonatal factors were obtained from hospital records. The location, retinal layer, and laterality of FH were recorded by 1 pediatric vitreoretinal specialist. Birth prevalence of FH. Secondary outcomes included rate of adverse events, risk factors for FH, hemorrhage characteristics, and adverse events. The birth prevalence of FH in this study was 20.3% (41/202 infants). Ninety-five percent of FHs involved the periphery, 83% involved the macula, and 71% involved multiple layers of the retina. The fovea was involved in 15% of FH cases (birth prevalence, 3.0%). No cases of bilateral foveal hemorrhage were found. Fundus hemorrhages were more common in the left eye than the right. Fundus hemorrhages were most commonly optic nerve flame hemorrhages (48%) and white-centered retinal hemorrhages (30%). Retinal hemorrhages were found most frequently in all 4 quadrants (35%) and more often were multiple than solitary. Macular hemorrhages most often were intraretinal (40%). Among the risk factors examined in this study, vaginal delivery compared with cesarean section (odds ratio [OR], 9.34; 95% confidence interval [CI], 2.57-33.97) showed the greatest level of association with FH. Self-identified ethnicity as Hispanic or Latino showed a protective effect (OR, 0.43; 95% CI, 0.20-0.94). Other study factors were not significant. Fundus

Cerebrovascular diseases are important causes of death in patients on maintenance hemodialysis. Recently, it has become clear that the presence of cerebral microbleeds (MBs) on T2 * -weighted magnetic resonance imaging (MRI) is closely related to intracerebral hemorrhages. This study investigated the incidence of MBs in chronic dialysis patients and prospective hemorrhagic complications of chronic dialysis patients with old intracerebral hemorrhages. Eighty patients (34 males, 46 females) with chronic renal failure, whose mean age was 62.9±11.4 years, were examined by MRI. The mean duration of hemodialysis was 7.8±6.3 years. MBs were found in 28 patients (35%) by T2 * -weighted MRI. Old intracerebral hemorrhages were seen in seven of the patients, and MBs were found in five (71%) of these seven patients. The frequency of old intracerebral hemorrhages was significantly higher in patients with MBs than in those without (p=0.048), and the numbers of MBs were significantly larger in patients with old intracerebral hemorrhages than in those without (p=0.0065). Three of the seven patients with old intracerebral hemorrhages had new hemorrhagic complications (two intracerebral hemorrhages and one cerebral microbleed) within a year. These intracerebral hemorrhages occurred in areas without MBs on the first T2 * -weighted MRI. T2 * -weighted MRI is useful for the detection of MBs, which may be a predictor of intracerebral hemorrhage. When a patient has a large number of MBs and old intracerebral hemorrhages, the risk of intracerebral hemorrhage undoubtedly increases. (author)

Full Text Available Retroperitoneal fibrosis (RPF is a rare disease characterized by the presence of fibroinflammatory tissue around the abdominal aorta and ureteral entrapment in most cases. Idiopathic RPF is frequently reported in association with autoimmune diseases; however, there have been few reports of idiopathic RPF associated with Hashimoto's thyroiditis. Here, we report a case of idiopathic RPF with Hashimoto's thyroiditis in a patient with a single functioning kidney, which was successfully treated by corticosteroid therapy and transient intraureteral stent insertion with a double-J catheter.

Pelvic retroperitoneal pneumography (PRP) and pelvic computed tomography (CT) were performed on 33 patients with rectal carcinoma in order to compare the usefulness of the two diagnostic procedures in the preoperative assessment of local malignant extramural invasion. Six PRP-negative patients in whom no free air was visualized in the retroperitoneal space surrounding the mass, were all assessed as having extramural invasion by CT scan and all had histologic evidence of invasion. Of 27 PRP-positive patients in whom free air was seen surrounding the mass, 18 were diagnosed as having extramural invasion on CT, 15 of whom had histologic proof of invasion. In the remaining 9 PRP-positive patients, there was no evidence of extramural invasion on the CT scans, but 5 patients showed evidence of invasion histologically. PRP, when positive, had an unacceptably high rate of being false positive and was therefore unreliable in assessing extramural invasion, whereas CT was able to detect, to some extent, extramural invasion which PRP failed to demonstrate. Based on these findings, we conclude that CT is more useful than PRP in the preoperative assessment of extramural invasion of rectal carcinoma, but is of limited diagnostic value when negative.

Background and purpose Although unclear-onset ischemic stroke, including wake-up ischemic stroke, is drawing attention as a potential target for reperfusion therapy, acute unclear-onset intracerebral hemorrhage has been understudied. Clinical characteristics, hematoma features, and outcomes of patients who developed intracerebral hemorrhage during sleep or those with intracerebral hemorrhage who were unconscious when witnessed were determined. Methods Consecutive intracerebral hemorrhage patients admitted within 24 hours after onset or last-known normal time were classified into clear-onset intracerebral hemorrhage and unclear-onset intracerebral hemorrhage groups. Outcomes included initial hematoma volume, initial National Institutes of Health Stroke Scale score, hematoma growth on 24-hour follow-up computed tomography, and vital and functional prognoses at 30 days. Results Of 377 studied patients (122 women, 69 ± 11 years old), 147 (39.0%) had unclear-onset intracerebral hemorrhage. Patients with unclear-onset intracerebral hemorrhage had larger hematoma volumes (p = 0.044) and higher National Institutes of Health Stroke Scale scores (p Hematoma growth was similarly common between the two groups (p = 0.176). There were fewer patients with modified Rankin Scale (mRS) scores of 0-2 (p = 0.033) and more patients with mRS scores of 5-6 (p = 0.009) and with fatal outcomes (p = 0.049) in unclear-onset intracerebral hemorrhage group compared with clear-onset intracerebral hemorrhage as crude values, but not after adjustment. Conclusions Patients with unclear-onset intracerebral hemorrhage presented with larger hematomas and higher National Institutes of Health Stroke Scale scores at emergent visits than those with clear-onset intracerebral hemorrhage, independent of underlying characteristics. Unclear-onset intracerebral hemorrhage patients showed poorer 30-day vital and functional outcomes than clear-onset intracerebral hemorrhage patients

Cerebral amyloid angiopathy (CAA) is an important cause of lober intracerebral hemorrhage in the elderly. Although leptomeningeal and cortical arteries with the deposition of the amyloid β-protein (Aβ) have been thought to rupture in CAA, the pathogenesis of CAA-related hemorrhage still remains obscure. We studied 10 cases of CAA according to the Boston criteria from April 2006 to July 2009 in Omaezaki Municipal Hospital. Based on clinical data, we examined the primary site of hemorrhage and hypothesized the mechanisms of bleeding. Intracerebral hematoma evacuation was performed to alleviate neurological deteriolation in 2 patients and to make diagnosis in 3 patients. The surgical specimens were pathologically examined. The characteristic MR images of CAA related hemorrhage were characterized by microbleeds, superficial siderosis, subpial or subarachnoid hemorrhage, subcortical hemorrhage and lober intracerebral hemorrhage. Chronological images obtained in 1 patient revealed that lober intracerebral hemorrhage developed from microbleed with subpial hemorrhage without subarachnoid hemorrhage in one side of the cortex in the affected facing cerebral sulci. Operative findings showed subpial and subarachnoid hemorrhages around the cortical veins on the affected cerebral sulci in all cases. Abnormal fragile vessels existed in one side of the cortex of the affected sulci but not in the other side of the cortex. Complete hamatoma evacuation was performed in 4 cases. The surgical specimens of the hematoma and the adjacent brain parenchyma were pathologically examined by tissue staining with hematoxylin-eosin and Congo red. Many vessels in subpial, subcortical and subarachnoid space along the cerebral sulci were deposited with Aβ. From these findings, we speculated that the primary hemorrhage related to CAA occurred from the cortical arteries with Aβ deposition in the subpial space along the cerebral sulci and formed a lober intracerebral hematoma.

Massive hemorrhage is associated with coagulopathy and high mortality. The transfusion guidelines up to 2006 recommended that resuscitation of massive hemorrhage should occur in successive steps using crystalloids, colloids and red blood cells (RBC) in the early phase, and plasma and platelets...... in the late phase. With the introduction of the cell-based model of hemostasis in the mid 1990ties, our understanding of the hemostatic process and of coagulopathy has improved. This has contributed to a change in resuscitation strategy and transfusion therapy of massive hemorrhage along with an acceptance...... outcome, although final evidence on outcome from randomized controlled trials are lacking. We here present how we in Copenhagen and Houston, today, manage patients with massive hemorrhage....

Splenic Involvement in Hereditary Hemorrhagic Telangiectasia

Full Text Available A 33-year-old man who presented with prolonged epigastric pain was referred to our hospital. He had experienced recurrent epistaxis and had a family history of hereditary hemorrhagic telangiectasia. Computed tomography and magnetic resonance imaging revealed splenomegaly and a 9 cm hypervascular mass in his spleen. Computed tomography also showed a pulmonary arteriovenous malformation and heterogeneous enhancement of the liver parenchyma, suggesting the presence of arteriosystemic shunts and telangiectases. Based on these findings, the patient was definitely diagnosed with hereditary hemorrhagic telangiectasia according to Curaçao criteria. He underwent splenectomy, and his symptoms disappeared after surgery. Pathological examination of the resected specimen revealed that the hypervascular lesion of the spleen was not a tumor but was composed of abnormal vessels associated with hereditary hemorrhagic telangiectasia. Symptomatic splenic involvement may be a rare manifestation of hereditary hemorrhagic telangiectasia but can be revealed by imaging modalities.

A rare case of retroperitoneal malignant triton tumor invading renal vein and small intestine

Full Text Available Introduction. Malignant Triton tumor is a very rare malignant peripheral nerve sheath tumor with rhabdomyosarcomatous differentiation. Most of those tumors occur in patients with von Recklinghausen’s disease or as a late complication of irradiation and commonly seen in the head, neck, extremities and trunk. Case report. We reported retroperitoneal malignant Triton tumor in a 57-year-old female patient. Skin lesions were not present, and there was no family history of neurofibromatosis or previous irradiation. The presented case is one of a few recorded in the specialized literature that occurs in the retroperitoneal space in sporadic form. In this case, tumor consisted of a multilobular mass was in close relation with the abdominal aorta and inferior vena cava and involved the renal vein with gross invasion of the small intestine. The patient underwent total resection of the tumor and left nefrectomy was performed. The small intestine 10 cm in length was also resected and end-to-end anastomosis was conducted. The postoperative course was uneventful and the patient was discharged from the hospital ten days after the surgery. Conclusion. Diagnostically, it is crucial to recognize this uncommon histological variant because malignant Triton tumor has a worse prognosis than classic malignant peripheral nerve sheath tumor does. The use of the immunohistochemistry is essential in making the correct diagnosis. Only appropriate pathological evaluation supported by immunostaining with S-100 protein and desmin confirmed the diagnosis. Aggressive surgical management treatment improves the prognosis of such cases with adjuvant radiotherapy.

A case of calcified subdural hematoma associated with hypertensive intracerebral hemorrhage is reported. A left frontal subdural hematoma with left putaminal hemorrhage was incidentally found when a CT scan was performed to evaluate right hemiparesis and aphasia in a 55-year-old man. The putaminal hemorrhage was not very extensive, but his clinical symptoms were rather serious. Not only the putaminal hemorrhage, but also the presence of the calcified subdural hematoma was considered to have caused his clinical deterioration. The subtotal removal of the calcified subdural hematoma brought about a good result. (author)

The purpose of this study is to evaluate the signal characteristics of intracranial hemorrhage, as seen on fluid attenuated inversion recovery (FLAIR) MR imaging according to various stages, and to compare FLAIR imaging with spin-echo T1- and T2-weighted MR imaging. We retrospectively evaluated fast FLAIR images along with spin-echo T1- and T2 weighted MR images of 32 lesions in 25 patients (12 males and 14 females, aged 3 - 84 yrs) with intracranial hemorrhagic lesions. For imaging, 1.5 T unit was used, and the nature of the lesions was found to be as follows : intracranial hemorrhage (n=15); tumor (n=9); infarction (n=4); arteriovenous malformation (n=3); and arachnoid cyst with hemorrhage (n=1). On the basis of spin-echo MR imaging, lesions were classified as acute, early subacute, late subacute, early chronic, or late chronic stage. The signal characteristics of intracranial hemorrhage were analysed in accordance with each staging, as seen on MR FLAIR imaging, and compared to the staging seen on spin-echo T1- and T-2 weighted MR imaging. The signal intensity of intracranial hemorrhage, as seen on FLAIR imaging, was not characteristic; it was similar to that of T2WI during the acute and subacute stages, and similiar to that of T1WI during the chronic stage. When used together with spin-echo T1- and T2-weighted MR imaging, however, FLAIR imaging may be useful for the classification of chronic intracranial hemorrhage as either early or late stage.

The late histopathological effects of intraoperative radiotherapy (IORT) on retroperitoneal tissues, intestine, and bile duct were investigated in dogs. Fourteen adult foxhounds were subjected to laparotomy and varying doses (0-45 Gy) of IORT (11 MeV electrons) delivered to retroperitoneal tissues including the great vessels and ureters, to a loop of defunctionalized small bowel, or to the extrahepatic bile duct. One control animal received an aortic transection and reanastomosis at the time of laparotomy; another control received laparotomy alone. This paper describes the late effects of single-fraction IORT occurring 3-5 years following treatment. Dogs receiving IORT to the retroperitoneum through a 4 X 15 cm portal showed few gross or histologic abnormalities at 20 Gy. At doses ranging from 30-45 Gy, radiation changes in normal tissues were consistently observed. Retroperitoneal fibrosis with encasement of the ureters and great vessels developed at doses ≥30 Gy. Radiation changes were present in the aorta and vena cava at doses ≥40 Gy. A 30 Gy dog developed an in-field malignant osteosarcoma at 3 years which invaded the vertebral column and compressed the spinal cord. A 40 Gy animal developed obstruction of the right ureter with fatal septic hydronephrosis at 4 years. Animals receiving IORT through a 5 cm IORT portal to an upper abdominal field which included a defunctionalized loop of small bowel, showed few gross or histologic abnormalities at a dose of 20 Gy. At 30 Gy, hyaline degeneration of the intestinal muscularis layer of the bowel occurred. At a dose of 45 Gy, internal intestinal fistulae developed. One 30 Gy animal developed right ureteral obstruction and hydronephrosis at 5 years. A dog receiving 30 Gy IORT through a 5 cm portal to the extrahepatic bile duct showed diffuse fibrosis through the gastroduodenal ligament. These canine studies contribute to the area of late tissue tolerance to IORT. 7 refs., 3 figs., 5 tabs

Background Children with untreated brain arteriovenous malformations (bAVM) are at risk of encountering life-threatening hemorrhage very early in their lives. The primary aim of invasive treatment is to reduce unfavorable outcome associated with a bAVM rupture. A better understanding of the morbidity of bAVM hemorrhage might be helpful for weighing the risks of untreated bAVM and invasive treatment. Our aim was to assess the clinical outcome after bAVM rupture and identify features to predict severe hemorrhage in children. Methods We identified all consecutive children admitted to our institution for bAVMs between July 2009 and December 2014. Clinical outcome after hemorrhagic presentation and subsequent hemorrhage was evaluated using the modified Rankin Scale (mRS) for children. The association of demographic characteristics and bAVM morphology with severe hemorrhage (mRS >3 or requiring emergency hematoma evacuation) was studied using univariate and multivariable regression analyses. A nomogram based on multivariable analysis was formulated to predict severe hemorrhage risk for individual patients. Results A total of 134 patients were identified with a mean treatment-free follow-up period of 2.1 years. bAVM ruptured in 83 (62%) children: 82 had a hemorrhage at presentation and 6 of them experienced a recurrent hemorrhage during follow-up; 1 patient had other diagnostic symptoms but bled during follow-up. Among them, 49% (41/83) had a severe hemorrhage; emergency hematoma evacuation was required in 28% of them (23/83), and 24% (20/83) remained as disabled (mRS ≥ 3) at last follow-up. Forty-six percent (38/82) of children with hemorrhagic presentation were severely disabled (mRS >3). Forty-three percent (3/7) were severely disabled after subsequent hemorrhage. The annual rate of severe subsequent hemorrhage was 1% in the overall cohort and 3.3% in children with ruptured presentation. All the subsequent severe hemorrhage events occurred in children with severe

Spontaneous retroperitoneal hematoma (SRH) is a potentially fatal clinical entity requiring immediate recognition and intervention. The clinical records of 18-year-old and older patients admitted to the University Hospital Marqués de Valdecilla from 2003 to 2013 were reviewed. "Spontaneous" was defined as unrelated to trauma, invasive procedures or bleeding due to aortic aneurysm rupture. Thirty-four patients with SRH (44% were on anticoagulant drugs). One-third of cases had chronic renal insufficiency. Abdominal pain was the most common symptom both in anticoagulated and non-anticoagulated patients (80% in anticoagulated and 89% in non-anticoagulated patients). About one half of the patients developed shock. A CT scan was the most commonly performed diagnostic test, followed by abdominal ultrasound. Most cases were managed conservatively (80%). More than half of the patients (66%) restarted anticoagulation therapy after the acute event with a mean delay of 19 days (range 2-90 days). None of them suffered a new bleeding episode. Restarting the anticoagulation treatment after hematoma resolution seems to be a safe practice. There is an increasing frequency of SRH in non-anticoagulated patients.

Objective: To study the etiology and the treatment of spontaneous non-aneurysmal subarachnoid hemorrhage. Methods: Twenty five cases of cerebral vessel angiography negative patients were analysed retrospectively, the majority of them had been undergone CT, DSA, MRI examination in order to define the etiological factor. Results: Among them, there was 1 case of spinal arteria-vena malformation, 1 case of hemorrhagic blood and 2 cases according to the revealing of MRI could be explained as bled vascular-occult malformation or cavernous angioma. Conclusion: The management and prognosis of patients in whom non-aneurysm is founded on the initial angiogram depends on the pattern of hemorrhage of the initial CT scanning, repeated angiography should be avoided for the case of premise encephalic non-aneurysmal SAH and MRI examination may be indicated to defining of etiological factors

Full Text Available The purpose of present study was to assess the effects of thoracic epidural anesthesia on splanchnic perfusion, bacterial translocation and histopathologic changes in experimental hemorrhagic shock in short-tailed macaques (Macaca nemestrina. Sixteen Macaca nemestrinas were randomly assigned to one of two groups i.e. the lidocaine group (n = 8, receiving general anesthesia plus lidocaine thoracic epidural anesthesia; and the saline group (n = 8, receiving general anesthesia alone as control. Hemorrhagic shock was induced by withdrawing blood gradually to a mean arterial pressure (MAP of 40 mm Hg, and maintained for 60 minutes. Animals were then resuscitated with their own blood and ringer lactate solution (RL. After resuscitation, epidural lidocaine 2% was given in the lidocaine group and saline in the control group. Resuscitation that was performed after one hour hemorrhagic shock, with hemodynamic variables and urine output returned to normal, revealed there was no improvement of splanchnic perfusion. PgCO2, P(g-aCO2, and pHi remained in critical value and tended to deteriorate in the saline group. Contrast to saline group, splanchnic perfusion in lidocaine group tended to improve. This condition was supported by the finding of less bacterial translocation and better histopathologic changes in lidocaine thoracic epidural anesthesia group than in saline group. This study concludes that lidocaine thoracic epidural anesthesia attenuates splachnic hypoperfusion in post-resuscitation hemorrhagic shock in Macaca nemestrina.

Vaginal delivery of the macrosomic fetus may result in hemorrhage of intra-abdominal organs. Mostly affected organs are the liver and adrenal glands. Hemorrhage of liver is usually occurs as a subcapsular hemorrhage and it is clinically presented an abdominal mass without symptoms of anemia. But intraparenchymal hemorrhage of liver is very rare and there is no sign of abdominal mass. However, in contrast to subcapsular hemorrhage, symptoms of anemia are rapidly developed in newborns. A macrosomic newborn by vaginal delivery at term. Within 6 h after delivery, the patient showed pallor without tachycardia and hypotension. In laboratory studies, hemoglobin level failed from 14 g/dL to 10 g/dL within 6 h. Physical examination revealed no signs of abdominal mass. Intraparenchymal hemorrhage in the sixth segment of liver and right adrenal hemorrhage were detected on the ultrasonographic scan. Hepatic function tests were normal in the whole follow-up period, and hemorrhage resolved within two weeks. Following months after discharge, adrenal hemorrhage also resolved without any complication. Hepatic hemorrhages, causing hemorrhagic anemia in neonates, usually occur in subcapsular form. Intraparenchymal hepatic hemorrhage should especially be considered in those newborns, which are rapidly developed symptoms of anemia without any abdominal mass.

A 51-year-old man was referred to our hospital on May, 24, 1978, with complaints of lower abdominal pain, lower abdominal mass, constipation and pollakisuria. Physical examination revealed a lower abdominal tumor which was smooth, elastic soft and of childs' head size. IVP and urethrography revealed left nonvisualizing kidney, right hydronephrosis and deformity of bladder. CT scan revealed a large intrapelvic mass. Under the diagnosis of retroperitoneal tumor, operation was done on June, 29, 1978. Adhesive changes between the tumor, sacrococcyx and left internal iliac artery was so severe that the tumor could not be resected, and only biopsy-specimen was taken. Pathohistological diagnosis of the tumor was carcinoid tumor. He received postoperative radiation therapy with total dosis of 5000 rad in 5 weeks, and complete remission was obtained. Now, more than 5 years have passed after operation, no recurrence was detected. Carcinoid tumors are rare and generally are not radioeffective, but some cases without carcinoid syndrome, including our case, are radioeffective. So radiation therapy should be the second choice of treatment for carcinoid tumor. (author)

Diabetic retinopathy is one of the most common cause of legal blindness. Five to 10% of diabetic patients suffer from the proliferative diabetic retinopathy which includes the formation of new vessels on the retina and optic disc which can be complicated as vitreous hemorrhage and tractional retinal detachment. Pars plana vitrectomy along with laser photocoagulation is being used for the management of vitreous hemorrhage. In our study we used injection avastin one week before surgery to see its role on the incidence of rebleed after vitrectomy in diabetic vitreous hemorrhage. Materials and Methods; Fifty patients were divided into 2 equal groups on the basis of simple random sampling. 25 patients in Group I were operated with routine pars plana vitrectomy with endolaser photo- coagulation while in Group II all the 25 patients were given injection avastin intra-vitreally one week before surgery. Evaluation was done on the first post operative day, first follow up visit (one week) and after one month to see the incidence of re-bleed. Chi-square test was used for statistical analysis. Results: Fifty patients divided into two groups. In Group I, 3 patients had recurrent vitreous hemorrhage on first post-operative day, 3 patients had re-bleed on first follow up visit, and only 2 patients had re-bleed after one month. In Group II, none of the patients had recurrent vitreous hemorrhage on first post-operative day and on first follow-up visit (one week) while 2 patients had re-bleed after one month. Conclusion: Injection intravitreal Avastin (Bevaci- zumab) one week before surgery significantly reduces the risk of vitreous hemorrhage after vitrectomy in diabetic patients. (author)

There are diverse etiologies of diffuse pulmonary hemorrhage, so specific diagnosis may be difficult. Conventional radiography tends to be misleading as hemoptysis may lacking in patients with hemorrhagic anemia. Diffuse pulmonary hemorrhage should be differentiated from focal pulmonary hemorrhage resulting from chronic bronchitis, bronchiectasis, active infection (tuberculosis) neoplasia, trauma, or embolism.

Crimean-Congo hemorrhagic fever (CCHF) is an acute infectious disease caused by CCHF virus (CCHFV), a member of the family Bunyaviridae, genus Nairovirus. The case fatality rate of CCHF ranges from 10-40%. Because CCHF is not present in Japan, many Japanese virologists and clinicians are not very familiar with this disease. However, there remains the possibility of an introduction of CCHFV or other hemorrhagic fever viruses into Japan from surrounding endemic areas. Development of diagnostic laboratory capacity for viral hemorrhagic fevers is necessary even in countries without these diseases. At the National Institute of Infectious Diseases, Tokyo, Japan, laboratory-based systems such as recombinant protein-based antibody detection, antigen-capture and pathological examination have been developed. In this review article, epidemiologic and clinical data on CCHF in the Xinjiang Uygur Autonomous Region, compiled through field investigations and diagnostic testing utilizing the aforementioned laboratory systems, are presented. CCHFV infections are closely associated with the environmental conditions, life styles, religion, occupation, and human economic activities. Based on these data, preventive measures for CCHFV infections are also discussed.

Our purpose was to assess anatomical and functional outcomes of vitrectomy in pediatric cases of Terson syndrome. A total of 11 eyes of seven children diagnosed with Terson syndrome secondary to traumatic brain injury and 17 eyes of 12 children diagnosed with Terson syndrome secondary to nontraumatic brain hemorrhage who had 20-gauge or 23-gauge pars plana or pars plicata vitrectomy were included in this retrospective study. The primary outcome was the change in visual acuity from the preoperative examination to postoperative final follow-up. Secondary outcomes were anatomic surgical success and postoperative complications. The mean time between diagnosis and surgery was 62 ± 35 days (range, 30-150), and the average age at the time of the surgery was 4.5 ± 6.4 years (range, 3 months to 17 years). The mean preoperative logarithm of the minimum angle of resolution (logMAR) (Snellen) best corrected visual acuity (BCVA) was 2.6 ± 0.7 (20/7260) (n = 9) and in the remaining 19 eyes it was recorded as noncentral, unsteady, nonmaintained fixation. The mean follow-up period was 50 ± 54 months (range, 12-192 months). At the last follow-up visit, the mean logMAR BCVA was 0.46 ± 0.6 (20/60) (n = 19) and in eight eyes it was recorded as fix-and-follow. One eye developed a retinal detachment 14 months after the first operation, and one eye developed an epiretinal membrane after 2 years. Anatomical success was recorded in all patients at the final visit. In children with massive vitreous hemorrhage secondary to Terson syndrome, vitrectomy is an effective procedure and offers a rapid visual improvement. Earlier surgical treatment prevents amblyopia and blood-related potential complications.

Atrial natriuretic peptide (ANP) is a well-known prognostic marker of outcome and mortality in patients with cardiovascular disease. Midregional proatrial natriuretic peptide (MR-proANP) is a stable fragment of the ANP precursor hormone. As a prognostic marker after ischemic stroke, it reliably predicts poststroke mortality and functional outcome. This study aimed to analyze the prognostic value of MR-proANP in patients with hemorrhagic stroke, i.e. subarachnoid (SAH) and intracerebral hemorrhage (ICH). MR-proANP was analyzed in patients with spontaneous SAH or spontaneous ICH. All patients were prospectively randomized into two treatment arms: (1) a prophylactic normothermia group with a target core temperature 36.5°C using endovascular cooling, and (2) a control group with conventional stepwise predefined fever management using antipyretic medication and surface cooling. Blood samples were obtained on admission and on days 4 and 7. Measurement of MR-proANP was performed in serum using sandwich immunoassay. The primary endpoint was functional outcome [assessed by the Glasgow Outcome Score (GOS)] and the secondary endpoints were mortality within 180 days after hemorrhagic stroke and influence of temperature on MR-proANP. A favorable outcome was defined as GOS 4-5, and the patients were considered to have a poor outcome with a 180-day GOS score between 1 and 3. Analysis of MR-proANP was performed in 24 patients with spontaneous SAH and 22 patients with spontaneous ICH. MR-proANP was elevated on days 4 and 7 as compared to baseline levels (p 120 pmol/l) were associated with increased mortality and poor outcome (after 180 days; p mortality after 180 days in patients with hemorrhagic stroke. Endovascular temperature control had no significant influence on MR-proANP levels.

Isolated Retroperitoneal Hydatid Cyst Invading Splenic Hilum

Safak Ozturk

2014-01-01

Full Text Available Introduction. Hydatid disease (HD is an infestation that is caused by the larval stage of Echinococcus granulosus. The liver is affected in approximately two-thirds of patients, the lungs in 25%, and other organs in a small proportion. Primary retroperitoneal hydatid cyst is extremely rare. The most common complaint is abdominal pain; however, the clinical features of HD may be generally dependent on the location of the cyst. Case Presentation. A 43-year-old female was admitted with the complaint of abdominal pain. Her physical examination was normal. Computed tomography (CT revealed a 17 × 11 cm cystic lesion, with a thick and smooth wall that is located among the left liver lobe, diaphragm, spleen, tail of the pancreas, and transverse colon and invading the splenic hilum. Total cystectomy and splenectomy were performed. Pathological examination was reported as cyst hydatid. Discussion. Cysts in the peritoneal cavity are mainly the result of the spontaneous or traumatic rupture of concomitant hepatic cysts or surgical inoculation of a hepatic cyst. Serological tests contribute to diagnosis. In symptomatic and large hydatid peritoneal cysts, surgical resection is the only curative treatment. Total cystectomy is the gold standard. Albendazole or praziquantel is indicated for inoperable and disseminated cases. Percutaneous aspiration, injection, and reaspiration (PAIR technique is another nonsurgical option.

Cerebral blood flow in patients with hypertensive intracerebral hemorrhage

1984-01-01

Cerebral blood flow (CBF) is usually decreased in patients with hypertensive intracerebral hemorrhage. A total of 81 regional CBF measurements were performed using an Anger-type dynamic gamma camera with the Xe-133 intracarotid injection technique in 23 patients with thalamic hemorrhage, 18 with small putaminal hemorrhage, and 5 with large putaminal hemorrhage. The results were as follows: Bilateral CBF in thalamic hemorrhages was markedly reduced from 1 week to 2 or 3 weeks after onset; it then showed a tendency to increase from 4 weeks to 3 months. In putaminal hemorrhages, however, CBF in the affected hemisphere did not tend to increase despite increased CBF in the contralateral hemisphere. CBF of the affected hemisphere was plotted against the hematoma volume, and the biphasic curve showed an initial steep and subsequent gentle slope in both putaminal and thalamic hemorrhages. The degree of CBF reduction in the affected hemisphere was more evident in thalamic than in putaminal hemorrhages. However, the flow reduction in the contralateral hemisphere was more obvious in thalamic than in putaminal hemorrhages. Factors such as mean arterial blood pressure, partial pressure of arterial carbon dioxide, cerebrospinal fluid pressure, hematocrit and the degree of involvement of the internal capsule, as shown on CT scan were not directly related to CBF reduction. In conclusion, it is unlikely that the mass effect of the hematoma plays an important role in the discrepancy between CBF reduction in putaminal and thalamic hemorrhages. Rather, the discrepancy may result from the impairment of respective anatomical sites in the thalamic and putaminal regions. It is also suggested that ipsilateral as well as contralateral CBF reduction is probably caused by the decreased cortical metabolic demand. This may be based on the disruption of the transneural fiber pathways, which connect both the thalamus and putamen to the cerebral cortex. (author)

From June 1980 to May 1993, 52 patients with a mean age of 49, underwent a retroperitoneal pelvic lymph node laparoscopy procedure for cervix carcinoma classified as stage IA (14), IB (12), IIA (6), IIB (14), IIIB(3), IVA (3). Two techniques were used: a retroperitoneoscopy in 16 cases and a panoramic retroperitoneal pelviscopy (PRPP) in 36 cases. The aim was to define, with a better accuracy, the pelvic lymph node status, to adapt the target volume, and to estimate the morbidity.More nodes were biopsied with PRPP than with retroperitoneoscopy (p<0.05). There was a disagreement between the conventional radiologic assessment and the histological results in 28.6%. Specificity is 100%. Intra-operative and post-surgical morbidity was equivalent in the two procedures. One grade 3 urinary late morbidity (3%) was observed among the 33 patients who underwent a pelvic external irradiation. There was no morbidity of the gastro-intestinal tract. Discussion deals with the support offered by the two laparoscopic procedures to define the pelvic lymph node status, to choose the planning target volume, and to precise the lymph node boost.

CT scans were analysed retrospectively in 130 patients with subarachnoid hemorrhage (SAH) due to ruptured cerebral aneurysm to evaluate the relationship of the locations of aneurysms and the patterns of hemorrhage. Hemorrhage corresponded to the site of aneurysmal origin in a general way and in more specific ways to anterior communicating and middle cerebral artery aneurysms when there was parenchymal or cisternal hemorrhage. In anterior communicating artery aneurysm, SAH in the interhemispheric fissure, both sylvian fissures, and basal cistern was usually noted and intracerebral hemorrhage in anteroinferior frontal lobe was sometimes associated. In cases of middle cerebral artery aneurysm, hemorrhage in the ipsilateral sylvian fissure, interhemispheric fissure, and ipsilateral basal cistern was usual. Intracerebral hemorrhage in lateral temporal lobe was sometimes associated. Posterior communicating artery aneurysm demonstrated SAH in the ipsilateral basal cistern or in entire cisternal spaces specifically, so with higher incidence of involvement of the quadrigeminal and superior cerebellar cistern than anterior cerebral or middle cerebral artery aneurysm. We suggest the locations of aneurysm might be predicted with patterns of SAH and / or associated intracerebral hemorrhage with CT

1. After hemorrhage of 21% blood volume (0.9% body weight) blood pressure (BP) and heart rate (H.R.) of unanesthetized bluefish (Pomatomus saltatrix) recovered within 5 min. 2. Phentolamine blocked this recovery. 3. Atropine increased control H.R. from 48 to 87 per min, and to 108 after hemorrhage, with delay of BP recovery to 10 min. 4. With small, repeated hemorrhages every 20 min, hemodilution and recovery of BP occurred between hemorrhages. Removal of 27% blood volume resulted in only temporary recovery. 5. Thirty min after hemorrhage, plasma epinephrine was 5 x and norepinephrine 8 x control. 6. Thus, bluefish tolerate hemorrhage with initial vasoconstriction via alpha-adrenergic pathways, and hemodilution.

Retroperitoneal Malignant Peripheral Nerve Sheath Tumor Replacing an Absent Kidney in a Child

Full Text Available Malignant peripheral nerve sheath tumors (MPNSTs are nonrhabdomyosarcoma soft tissue sarcomas with rare occurrence in children specially in the retroperitoneum. We describe a young child who presented with an abdominal mass. Both ultrasound and computed tomography revealed a large right-sided abdominal mass in the anatomic place of right kidney, while no kidney or ureter was observed at that side. He underwent surgical resection of the tumor with a primary impression of Wilms tumor. To the authors’ knowledge, this is the first case of retroperitoneal malignant peripheral nerve sheath tumor and absent kidney. This case suggests the very rare probability of association of MPNSTs in children with genitourinary tract anomalies such as renal agenesis.

Ischemic and hemorrhagic strokes are associated with severe functional disability and high mortality. Except for recombinant tissue plasminogen activator, therapies targeting the underlying pathophysiology of central nervous system (CNS) ischemia and hemorrhage are strikingly lacking. Sur1-regulated channels play essential roles in necrotic cell death and cerebral edema following ischemic insults, and in neuroinflammation after hemorrhagic injuries. Inhibiting endothelial, neuronal, astrocytic and oligodendroglial sulfonylurea receptor 1-transient receptor potential melastatin 4 (Sur1-Trpm4) channels and, in some cases, microglial KATP (Sur1-Kir6.2) channels, with glibenclamide is protective in a variety of contexts. Robust preclinical studies have shown that glibenclamide and other sulfonylurea agents reduce infarct volumes, edema and hemorrhagic conversion, and improve outcomes in rodent models of ischemic stroke. Retrospective studies suggest that diabetic patients on sulfonylurea drugs at stroke presentation fare better if they continue on drug. Additional laboratory investigations have implicated Sur1 in the pathophysiology of hemorrhagic CNS insults. In clinically relevant models of subarachnoid hemorrhage, glibenclamide reduces adverse neuroinflammatory and behavioral outcomes. Here, we provide an overview of the preclinical studies of glibenclamide therapy for CNS ischemia and hemorrhage, discuss the available data from clinical investigations, and conclude with promising preclinical results that suggest glibenclamide may be an effective therapeutic option for ischemic and hemorrhagic stroke.

A spectrophotometric hemoglobin assay is widely used to estimate the extent of brain hemorrhage by measuring the amount of hemoglobin in the brain. However, this method requires using the entire brain sample, leaving none for histology or other assays. Other widely used measures of gross brain hemorrhage are generally semi-quantitative and can miss subtle differences. Semi-quantitative brain hemorrhage scales may also be subject to bias. Here, we present a method to digitally quantify brain hemorrhage using Photoshop and Image J, and compared this method to the spectrophotometric hemoglobin assay. Male Sprague-Dawley rats received varying amounts of autologous blood injected into the cerebral hemispheres in order to generate different sized hematomas. 24h later, the brains were harvested, sectioned, photographed then prepared for the hemoglobin assay. From the brain section photographs, pixels containing hemorrhage were identified by Photoshop and the optical intensity was measured by Image J. Identification of hemorrhage size using optical intensities strongly correlated to the hemoglobin assay (R=0.94). We conclude that our method can accurately quantify the extent of hemorrhage. An advantage of this technique is that brain tissue can be used for additional studies. Published by Elsevier B.V.

Computed Tomography has become increasingly important diagnostic method as the initial examination in the diagnosis of subarachnoid hemorrhage with direct detection of extravasated blood in basal cistern and cortical sulci. Furthermore, CT provides better and exact visualization of the presence, localization, extent and degree of intracerebral, intraventricular and subdural hemorrhage, infarction, hydrocephalus and rebleeding which may be associated with subarachnoid hemorrhage, and also could detect the causative lesions with contrast enhancement in many cases. The purpose of the paper is to describe the CT findings of subarachnoid hemorrhage due to various causes and to evaluate the diagnostic accuracy of CT in subarachnoid hemorrhage. Authors analysed a total of 153 cases with subarachnoid hemorrhage confirmed by lumbar puncture at Seoul National University Hospital from March 1979 to April 1981, with special emphasis on CT findings. All of the cases took CT scan and 125 cases of them angiography. The results are as follows: 1. Most prevalent age group was 4th to 6th decades (78%). The ratio of male to female was 1.1: 1. 2. Of 125 cases with angiography, aneurysm was a major cause (68%). Others were arterio-venous malformation (9.6%), Moya-moya disease (4%) and unknown (18.4%). 3. Of all 153 cases with CT scan, hemorrhage was demonstrated in 98 cases (64.1%); SAH in 72 cases (47.1%), ICH in 65 cases (42.5%), IVH in 34 cases (22.2%) and SDH in 1 case (0.7%). SAH combined with ICH was a major group (34.7%) in SAH. Detection rate of SAH was 68.3% within the first 7 days and 5.8% after 7 dyas. 4. In aneurysms, SAH was detected in 60 of 85 cases (70.6%); 88.1% within the first 7 dyas and 5.6% after 7 dyas. Anterior communicating artery was the most common site of the aneurysms (40%), in which detection rate of SAH was 100% within the first 7 days. SAH was combined with ICH in 38.3%. 5. On CT, SAH of unilateral Sylvian fissure was pathognomonic for ruptured MCA

Idiopathic retroperitoneal fibrosis (RPF) is a rare disease entity and its etiology is uncertain. We report two similar cases which showed an uncommon presentation of idiopathic RPF. A 66-year-old woman and an 80-year-old man presented with incidental findings of left renal pelvic mass-like lesions. Computed tomography revealed a soft tissue density mass replacing the left renal pelvis, which was suspicious for renal pelvic cancer, and the diagnosis of idiopathic RPF was surgically confirmed. To the best of our knowledge, a few cases of idiopathic RPF presenting with features of a localized unilateral renal pelvic mass mimicking renal pelvic cancer have been reported

Dasatinib-induced hemorrhagic colitis complicated with cytomegalovirus infection

Full Text Available A 69-year-old man with chronic-phase chronic myeloid leukemia was initially treated with 100 mg dasatinib once a day. Despite a major molecular response within 9 months, he developed hemorrhagic colitis 32 months after starting dasatinib. Colonoscopy identified multiple hemorrhagic ulcers in the transverse colon. The pathological findings indicated cytomegalovirus infection. Dasatinib was stopped and he was started on ganciclovir. Three months later, colonoscopy confirmed the disappearance of the hemorrhagic ulcers. Dasatinib is a second-generation tyrosine kinase inhibitor used to treat chronic myeloid leukemia. As a multi-kinase inhibitor that acts on SRC-family kinases, its broader off-target kinase-inhibitory activity may account for the adverse events of dasatinib. Although gastrointestinal bleeding is common in patients taking dasatinib, the combination of cytomegalovirus infection and hemorrhagic colitis in the absence of systemic immunodeficiency is rare. Based on this case of dasatinibinduced hemorrhagic colitis with cytomegalovirus infection, we describe a possible mechanism and effective treatment.

This paper determines the incidence and types of intracranial hemorrhage (ICH) in 1,696 patients treated with thrombolytic therapy for acute myocardial infarction (AMI). Thirteen of 1,696 patients experienced ICH, and their nonenhanced brain CT scans were reviewed. Their mean age was 62 years (range, 53-74 years), and nine of 13 were male. Six patients received tissue plasminogen activator (tPA), four streptokinase, two urokinase, and one tPA and urokinase. The hemorrhages were classified according to CT location: intraparenchymal (IPH), subarachnoid (SAH), subdural (SDH), and intraventricular (IVH). The incidence of ICH was 0.76%. There were 31 hemorrhages in 13 patients. Twelve hemorrhages were IPH, 10 were SDH, seven were SAH, and two were IVH. Excluding IVH, 24 of 29 hemorrhages (83%) were supratentorial

Central nervous system (CNS) involvement of scrub typhus infection is well known. Most CNS involvement of scrub typhus infection present as meningitis or encephalitis. We report on a patient suffering from hemorrhagic transformation of intracranial lesions caused by Orientia tsutsugamushi. A 53-year-old female farmer who was infected by scrub typhus was treated with doxycycline and recovered from the systemic illness. However, headache persisted. Brain radiologic studies revealed acute intracranial hemorrhage and enhancing lesion, which implied a CNS involvement. Hemorrhagic transformation of encephalitis by scrub typhus is very rare complication and to our best knowledge, this is the first report of hemorrhagic transformation of scrub typhus encephalitis. Clinician should consider the possibility of hemorrhagic transformation of encephalitis in cases of scrub typhus infection.

The patterns of renogram in patients with Korean hemorrhagic fever were evaluated with clinical course and renal hemodynamic changes in various clinical stages. The renal plasma flow was measured by hippuran blood clearance using 131 I-ortho-iodohippurate and hippuran renogram was analysed means of quantitative and qualitative methods in 26 patients of Korean hemorrhagic fever. The results obtained with this study were as follows;1) During the oliguric phase of Korean hemorrhagic fever, the renogram showed non-functioning (flat) or obstructive pattern. The group of patients with non-functioning pattern of renogram had more severe impairment of renal function and grave prognosis than the group with obstructive pattern of renogram. 2) During the diuretic phase, the renogram showed obstructive or dysfunction ar normal pattern, which was related with the recovery of renal function. Obstruction pattern of renogram was observed till the 2nd week of diuretic phase. Normal pattern of renogram began to appear by the 2nd week of diuretic phase. 3) During the convalescent phase of Korean hemorrhagic fever, 40% of patients showed dysfunction pattern of renogram, and the recovery of abnormal renogram in Korean hemorrhagic fever was more delayed than the recovery of clinical features and laboratory findings. 4) The renogram showed normal pattern 6 months after onset of Korean hemorrhagic fever in all cases. 5) There was significant correlationship between the pattern of renogram and the decrease of renal plasma flow in the patients with Korean hemorrhagic fever. The decrease of renal plasma flow was marked in the patients with non-functioning pattern of renogram and was least in the patients with dysfunction pattern of renogram. All above results suggested that the renogram reflects the effective renal plasma flow and degree of renal impairment, and the renogram may be one of the important indexes which could give us a more precise prognosis in Korean hemorrhagic fever.
