1/159. Arterial imaging.angioscopy, magnetic resonance angiography, computed tomography, and nuclear medicine are assuming an increasingly important role in arterial imaging. This review discusses recent advances in these modalities. angioscopy has proven valuable in monitoring intraoperative surgical procedures as well as percutaneous interventions. Carotid artery magnetic resonance angiography is gaining increasing acceptance in clinical practice. magnetic resonance angiography of the peripheral arteries is limited by spatial resolution and signal loss distal to the stenosis. The role of computed tomography in limiting the number of aortograms performed in evaluating aortic laceration remains controversial; however, several recent papers indicate its usefulness in evaluating clinically stable patients with abnormal chest radiographs. Computed tomography of abdominal aortic aneurysms may obviate the need for preoperative aortography in the majority of cases. Nuclear imaging for deep venous thrombosis using 111In-labeled antifibrin monoclonal antibodies was shown highly sensitive in its initial report.- - - - - - - - - - ranking = 1keywords = chest (Clic here for more details about this article) |
2/159. Hepatobiliary cystadenoma presenting with intermittent inferior vena caval obstruction.Hepatobiliary cystadenomas are rare benign tumours. They form as multilocular cysts in and around the liver. Their presentation is usually at a late stage when their size causes symptoms. We report a case of a 44-year-old woman presenting with abdominal pain, which was attributed to a multiloculate liver cyst. After intially refusing surgery she relented once intermittent inferior vena caval obstruction had developed. The cyst was found to be a hepatic cystadenoma.- - - - - - - - - - ranking = 8.3299484320948keywords = pain, abdominal pain (Clic here for more details about this article) |
3/159. Respiratory distress due to tracheal compression by the dilated innominate artery.The case reported is of an 88 yr old female with hypertension and respiratory distress. A chest radiograph revealed a widening of the upper mediastinum. Computed tomographic scanning revealed tracheal compression by the innominate artery, which was elongated and curved. After intubation, she was treated with antihypertensive drugs. This resulted in the remarkable recovery of the patient from respiratory distress. To the authors' knowledge, this is the first reported case of respiratory distress owing to tracheal compression by elongation and curvature of the innominate artery.- - - - - - - - - - ranking = 1.2495650283555keywords = chest, upper (Clic here for more details about this article) |
4/159. Unilateral painful vasospasm in the lower limbs of young women.The cases of five young women who presented with severe pain and associated vascular changes in one foot are described. The pain was spontaneous in onset and lasted for days, and its severity was such that none of the patients were able to walk without disability. Arteriography in three patients revealed arterial spasm. All had a good response from lumbar sympathectomy on the affected side.- - - - - - - - - - ranking = 26.560983895634keywords = pain (Clic here for more details about this article) |
5/159. Giant cervical epidural veins after lumbar puncture in a case of intracranial hypotension.A 29-year-old woman presented with dilated epidural veins and incapacitating headache after undergoing a lumbar puncture. Two months later, the results of follow-up MR imaging were normal. These findings suggest that temporary dilation of the epidural vein may occur in association with post-lumbar puncture intracranial hypotension syndrome. In these cases, it seems useful to confirm whether the patient has recently undergone a lumbar puncture.- - - - - - - - - - ranking = 0.48598736101548keywords = headache (Clic here for more details about this article) |
6/159. splenic vein occlusion secondary to tuberculous lymphadenitis at the splenic hilum: report of a case.We report a patient with splenic vein occlusion (SVO) secondary to tuberculosis. A 17-year-old male patient with mild epigastric pain and splenomegaly was found to have gastric varices by gastroscopy, and SVO by selective angiography. At operation, the splenic vein was occluded by hard fibrous tissue at the splenic hilum, and thus a splenectomy was performed. A microscopic examination of the tissue revealed caseous necrosis surrounded by epithelioid cells and Langhans-type giant cells. Although there were no other findings suggesting intestinal tuberculosis, it seemed that tuberculous lymphadenitis of the splenic hilum most likely caused the occlusion of the splenic vein. Because specific tests for tuberculosis were negative in both immunohistochemical staining for bacille Calmette-Guerin and polymerase chain reaction of dna for mycobacterium tuberculosis, the time of infection was assumed to have occurred a long time before. SVO can sometimes be seen in pancreatic diseases, but this patient with tuberculosis appears to be the first such reported case in the English literature.- - - - - - - - - - ranking = 4.4268306492723keywords = pain (Clic here for more details about this article) |
7/159. Bilateral radial artery pseudoaneurysms associated with bilateral ulnar artery atresia: a case report.Pseudoaneurysms of the radial artery are uncommon and most often localized in an area of penetrating vascular trauma or iatrogenic injury. Hypoplasia of the ulnar artery is even more rare. We report a case of bilateral radial artery pseudoaneurysms associated with complete absence of any ulnar contribution to the vascularity of the hand. A patient presented with bilateral tender masses adjacent to the anatomic snuff boxes that interfered with hand function. After confirming that these masses were bilateral radial artery pseudoaneurysms, resection of the pseudoaneurysms and microscopic reconstruction of the arterial segments preserved vascular integrity of the hands and provided relief of the patient's pain.- - - - - - - - - - ranking = 4.4268306492723keywords = pain (Clic here for more details about this article) |
8/159. hemoperitoneum following rupture of ectopic varix along splenorenal ligament in extrahepatic portal vein obstruction.A 29-year-old man with extrahepatic portal vein obstruction who underwent variceal eradication by sclerotherapy six years ago, was admitted with hypotension and abdominal pain. Abdominal paracentesis yielded frank blood. laparotomy showed bleeding from a large ectopic vessel along the splenorenal ligament. The vessel was ligated and the patient recovered.- - - - - - - - - - ranking = 8.3299484320948keywords = pain, abdominal pain (Clic here for more details about this article) |
9/159. Intravascular papillary endothelial hyperplasia in the kidney of a child.Intravascular papillary endothelial hyperplasia (IPEH) is a benign vascular lesion which is thought to represent an unusual form of organizing thrombus. A case of IPEH in the kidney of a 7-year-old girl is described. She suffered from intermittent flank pain and gross hematuria for 6 months. On radiological examinations, well-defined hypoechoic lesions were identified in the medullary portion of the left kidney. A well-demarcated, sponge-like mass was noted on gross examination. It was an intravascular mass lined by a fibrous capsule of various thicknesses. It was characterized by papillary fronds lined with benign endothelial cells. This is the first description of a renal IPEH in a child.- - - - - - - - - - ranking = 4.4268306492723keywords = pain (Clic here for more details about this article) |
10/159. Crushed stents in benign left brachiocephalic vein stenoses.Two hemodialysis patients presenting with left venous arm congestion due to benign catheter-induced stenosis of the left brachiocephalic vein were treated by angioplasty and stent placement. External compression of the stents was responsible for rapid recurrence of the symptoms. No osseous or vascular malformation could be identified. Mechanical constraints induced by respiratory chest wall motion and aortic arch flow-related pulsation are proposed to explain this observation. This potential hazard should be considered when stent placement into the left brachiocephalic vein is advocated.- - - - - - - - - - ranking = 1keywords = chest (Clic here for more details about this article) |
