1/75. Hepatic infarction in preeclampsia as part of the hellp syndrome: CT appearance.We describe the computed tomographic (CT) findings of hepatic infarctions in two preeclamptic pregnant women. These infarcts were part of the hellp syndrome (hemolysis, elevated liver function tests, and low platelets count). In both cases, CT disclosed features characteristic of multiple nonenhancing, low-attenuation, peripheral lesions with vessels coursing through and a mottled appearance. The recognition of such CT findings in liver disease associated with preeclampsia can establish the correct diagnosis.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
2/75. Orbital infarction and melting in a patient with systemic lupus erythematosus.OBJECTIVE: To present a patient with systemic lupus erythematosus who developed infarction and melting of the orbit secondary to her systemic disease. DESIGN: A case report. PARTICIPANT: A 61-year-old white woman with a 5-year history of systemic lupus erythematosus. methods: The patient presented with left orbital pain, limitation of extraocular movements, and a fistula from the ethmoid sinus to the upper eyelid. A detailed examination with computerized tomography, ultrasound, and a comprehensive medical evaluation with laboratory testing was performed. Histopathologic analysis with special stains of the orbital tissues was also performed. RESULTS: Histopathologic examination of the biopsy specimens revealed the features of an inflammatory process involving the orbit, similar to a panniculitis. These include a lymphocytic reaction with a predominance of plasma cells, vasculitis with occlusion, and thickening of the vessel walls, necrosis, and hyalinization of fat. CONCLUSION: This is a unique case in which infarction and melting of the entire orbital structures occurred in the presence of systemic lupus erythematosus. The underlying disease process is a lupus-related panniculitis. The authors stress that this is a very rare entity and that other diseases should be ruled out before entertaining this diagnosis.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |

4/75. Acute mesenteric infarction caused by small vessel disease.A case of acute mesenteric infarction caused by small vessel disease is reported. The patient recovered after 2 operations by which extensive bowel-resections were performed. The resected bowel showed intimal hyperplasia and atherosclerosis of the small mesenteric arteries. Since also thrombocytosis and increased platelet aggregation was demonstrated the main cause of thrombosis however is supposed to be hypercoagulability.- - - - - - - - - - ranking = 5keywords = vessel (Clic here for more details about this article) |
5/75. Isolated mesenteric injury due to blunt abdominal trauma.Isolated injuries of the small bowel mesentery or mesocolon with subsequent bowel infarction due to blunt abdominal trauma are rare. Two cases are described: 1 involving the mesentery to the terminal ileum and 1 involving the transverse mesocolon and middle colic artery, both with bowel infarction. The modes of clinical presentation and management of patients with injuries to the mesentery, mesocolon and mesenteric vessels following blunt trauma are described.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
6/75. Sclerosing encapsulating peritonitis and non-occlusive mesenteric infarction found at autopsy in a man who had undergone continuous ambulatory peritoneal dialysis: a histochemical and immunohistochemical study.This is a report of a post-mortem histological, histochemical, and immunohistochemical examination of a rare case of sclerosing encapsulating peritonitis (SEP) and non-occlusive mesenteric infarction (NOMI), two serious complications of continuous ambulatory peritoneal dialysis (CAPD), with which a man suffering hepatitis c virus (HCV)-induced liver cirrhosis for 7 years and trauma-induced paraplegia for 50 years had been treated for 1 year. The direct cause of death was encephalopathy caused by extreme hyperammonemia (11 250 microg/dL in serum). The autopsy revealed that the SEP had drastically reduced the length of the small intestine to 210 cm, 180 cm of which presented acute ischemic enteritis with Gram-negative bacterial infection. Histological examination of the SEP revealed that the exterior was composed of normal serosal elastic lamina, but with a cocoon-like appearance remarkably thickened by fibrosis to 3-8 times that of the normal subserosal layer and consisting of spindle cells and blood vessels, with some infiltration of mast cells and lymphocytes. The immunohistochemical examination of the spindle cells revealed few AE1/AE3( ) cells, HHF35( ) cells, and CD34( ) cells, many CD117( ) cells with slight proliferative activity based on MIB-1 positivity (proliferation index <1%), but no CD44( ) cells. It was concluded that either the few CD34( ) and/or the many CD117( ) cells were mesenteric stem cells that had originated from the serosa, proliferated, then differentiated into myofibroblasts or fibroblasts, producing collagen and hyaluronic acid in the matrix, leading to the gradual formation of the SEP, which was induced by the continual irritation of CAPD.- - - - - - - - - - ranking = 3.4031485793316keywords = blood vessel, vessel (Clic here for more details about this article) |
7/75. Bilateral choroidal infarction in a patient with antiphospholipid syndrome: a case report.PURPOSE: To report a case of bilateral choroidal infarction occurring as a complication of primary antiphospholipid syndrome. methods: The case notes of the patient were reviewed. RESULTS: A 25-year-old man with primary antiphospholipid syndrome and a previous history of deep vein thrombosis and pulmonary embolism, developed episcleritis and bilateral choroidal infarction, with deterioration of vision to 6/12 OD and counting fingers at 5 feet OS. Anticoagulation therapy with warfarin was administered and the patient's vision gradually improved to 6/6 OD and 6/9 OS. CONCLUSION: Primary antiphospholipid syndrome is associated with thrombotic phenomena, which may affect the ocular arterial and venous vasculature. Therefore, a detailed ophthalmological examination is warranted in those patients who present with ocular symptoms and deteriorating vision. Retinal fluorescein angiography is valuable in confirming the diagnosis when in doubt, and in determining the extent of vessel occlusion.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
8/75. Small intestinal infarction: a fatal complication of systemic oxalosis.Primary hyperoxaluria is a rare genetic disorder characterised by calcium oxalate nephrolithiasis and nephrocalcinosis leading to renal failure, often with extra-renal oxalate deposition (systemic oxalosis). Although ischaemic complications of crystal deposition in vessel walls are well recognised clinically, these usually take the form of peripheral limb or cutaneous ischaemia. This paper documents the first reported case of fatal intestinal infarction in a 49 year old woman with systemic oxalosis and advocates its consideration in the differential diagnosis of an acute abdomen in such patients.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
9/75. Sacral meningeal arteriovenous fistula supplied by branches of the hypogastric artery revealed by conus medullaris infarction.OBJECTIVE: Spinal dural arteriovenous fistulas (DAVF), the most common vascular malformations of the spine, are usually supplied by branches of the intercostal or lumbar arteries. Rarely, the DAVF are fed by branches of the hypogastric artery. Only 12 such cases have been reported. CASE REPORT: A 28 year-old man presented with a 2-month history of micturition dysfunction and progressive weakness of the legs. physical examination showed motor deficit of the lower limbs with brisk knee jerks, absent ankle reflexes and normal plantar reflexes. Cremasteric reflexes were absent. We noted hypoesthesia of the lower limbs with complete anesthesia of the perineum. MRI of the lumbo-sacral spine demonstrated an enlargement of the conus medullaris with high T2 signal intramedullary lesion. It showed also large intradural serpentine vessels. A left iliac angiogram disclosed a nidus of arteriovenous malformation (AVM) supplied by a lateral sacral artery and draining by two enlarged ascending perimedullary veins. No clinical improvement was observed after surgical removal of the AVM. CONCLUSION: The screening examination of choice for spinal DAVF remains MRI. When selective spinal arteriography is normal, we have to search for an unusual arterial supply particularly from the hypogastric artery.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
10/75. central nervous system and renal vasculitis associated with primary varicella infection in a child.A 7-year-old girl with primary varicella presented with encephalopathy and focal neurologic deficits 10 days after her first skin lesions appeared. She was discovered to have bilateral wedge-shaped renal infarctions, and ischemic lesions in the conus medullaris, cerebral cortex, and deep gray matter consistent with a medium and large vessel arteritis on magnetic resonance imaging. This complication has never before been reported in an immunocompetent child with primary varicella infection, and it represents a rare but serious complication of childhood chickenpox.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
