1/83. Ultrasonographic evaluation of tumorous lesions in digital vessels.ultrasonography has recently been used for evaluation of various conditions in Orthopaedics. Ultrasonographic examination is a noninvasive screening test especially for soft tissue masses. ultrasonography is also a useful and essential diagnostic tool in cardiovascular disorders because real-time images of heart and vessels can be obtained. However, there have been few reports which describe ultrasonographic evaluation of tumorous lesions in digital vessels. In this paper, such lesions in two cases were evaluated by ultrasonography. An aneurysm of the digital artery is one of the definite candidates for ultrasonographic evaluation.- - - - - - - - - - ranking = 1keywords = soft (Clic here for more details about this article) |
2/83. Popliteal venous aneurysm mimicking a soft tissue tumour. A case report.A case of a giant, thrombosed popliteal venous aneurysm without pulmonary embolism in a 53-year-old woman is reported. Despite thorough preoperative investigation including ultrasound and magnetic resonance imaging, this was misdiagnosed as a benign soft tissue tumour. During the operation the thrombosed venous aneurysm was resected and a vein graft from the contralateral saphenous vein was interposed. Popliteal venous aneurysm is a rare entity, presenting occasionally with local signs and symptoms and more often with pulmonary embolism. The clinician should therefore keep this in mind whenever dealing with a large, soft tissue popliteal fossa mass or looking for the cause of recurrent pulmonary embolism.- - - - - - - - - - ranking = 6keywords = soft (Clic here for more details about this article) |
3/83. Renal involvement of thrombotic thrombocytopenic purpura: special reference to the glomeruloid structures.We report the case of a 9-year-old girl with biopsy-proven renal thrombotic microangiopathy in thrombotic thrombocytopenic purpura (TTP), with particular reference to the glomeruloid structures. The renal biopsy sample from this TTP patient revealed platelet thrombus deposition, a glomeruloid structure and aneurysm with relative sparing of the glomeruli. The glomeruloid structure displayed a proliferation of mainly capillary-sized channels lined by factor viii-related, antigen-positive plump endothelial cells embedded in the edematous connective tissue. These glomeruloid vessels communicated with the aneurysmal segment at the end portion of the arteriolar branch. We believe that the glomeruloid structures in TTP represent not merely organization or recanalization of thrombus but rather active angiogenesis through aneurysmal dilation in the arteriolized vessel, probably initiated by platelet agglutination.- - - - - - - - - - ranking = 31.147869830805keywords = connective (Clic here for more details about this article) |
4/83. Successful resection of ductus arteriosus aneurysm in infancy.We report a case of thrombosed patent ductus arteriosus aneurysm in an infant. The aneurysm was detected accidentally on chest roentgenogram and presented as globular soft tissue density mass in left posterosuperior mediastinum. Resection of the aneurysm was performed without cardiopulmonary bypass. Two years after operation the patient is well and growing normally.- - - - - - - - - - ranking = 1keywords = soft (Clic here for more details about this article) |
5/83. Gastric pseudotumor.The authors present a case report of a pseudotumor of the stomach and a brief discussion about this very unusual entity. A 75-year-old female patient was admitted with melena and a large epigastric tumor; she underwent upper gastrointestinal endoscopy, abdominal ultrasound, magnetic resonance imaging, guided needle aspiration and angiography. Preoperative diagnostic hypothesis included a partially thrombosed aneurysm of the splenic artery, pancreatic cystic neoplasm with gastric invasion and pancreatic pseudocyst complicated with hemorrhage. laparotomy revealed a gastric tumor and the patient was submitted to a radical subtotal Billroth II gastrectomy. Only the pathologic examination revealed the unexpected definitive diagnosis of an organized intramural gastric hematoma. There were no postoperative complications and she remains asymptomatic 10 months after surgery.- - - - - - - - - - ranking = 0.70879095127248keywords = neoplasm (Clic here for more details about this article) |
6/83. Asymptomatic aneurysm of the proximal right subclavian artery: a rare ultrasound diagnosis.True aneurysms of otherwise normal subclavian arteries are uncommon peripheral vascular anomalies. Most patients with subclavian artery aneurysms are symptomatic by presenting neurologic signs. We report a young woman who had an asymptomatic true aneurysm of the right subclavian artery assumed to be of congenital origin. This case is unique in that the aneurysm was in the extremely rare anatomic location of the right supraclavicular fossa between the origins of the right subclavian artery and the vertebral artery. Aneurysms of the right subclavian artery may represent a potential pitfall in conventional gray-scale ultrasound of the neck particularly the supraclavicular fossa. Differential diagnosis includes cervical cyst, pharyngo-esophageal diverticulum, vascular anomalies, struma, enlarged lymph node, as well benign or malignant neoplasms. color duplex ultrasound should be performed as the method of choice for further analysis of suspected aneurysms. In this report the role of B-mode ultrasound and color duplex ultrasound is discussed in relation to digital subtraction- and MR angiography in confirmation of the diagnosis.- - - - - - - - - - ranking = 0.70879095127248keywords = neoplasm (Clic here for more details about this article) |
7/83. Atherosclerotic aneurysm of the intrathoracic segment of the subclavian artery: a case report.True aneurysms of the intrathoracic segment of the subclavian artery are extremely rare. atherosclerosis is the most common etiology. The surgical approach and timing of repair remain controversial. We successfully treated a patient with a large proximal subclavian artery aneurysm which was secondary to atherosclerosis. The patient was asymptomatic for 30 years as the aneurysm enlarged. Three-dimensional computed tomography provided the most useful information regarding anatomy of the cervical vasculature. The patient underwent closure of the inlet port of the aneurysm and repair using a 6-mm Dacron bypass graft (Gelsoft , VASCTEK, scotland) via a minimally invasive surgical approach.- - - - - - - - - - ranking = 1keywords = soft (Clic here for more details about this article) |
8/83. ehlers-danlos syndrome type IV and multiple aortic aneurysms--a case report.Beside atherosclerosis, aortic aneurysms can be part of the clinical spectrum of many systemic diseases, including infectious, inflammatory, genetic and, less often, congenital disorders. A 48-year-old white man presented with multiple large aneurysms of the aorta and its main branches. Medical history was unremarkable except for the presence of a softened abdominal mass since he was 28 years old. On the physical examination, an arterial murmur was heard over the left carotid artery and a palpable mass was noted in the whole right side of the abdomen. No skin or joint abnormalities were noted. aortography, computed tomography, and magnetic resonance angiography showed multiple large aneurysms of the descending thoracic and abdominal aorta. Aneurysms of the innominate, left subclavian, and carotid arteries were also seen. This case resembles those previously reported, in which multiple aortic aneurysms were associated with abnormalities of the type III procollagen gene (COL3A1). Although the classic stigmas of the ehlers-danlos syndrome type IV were lacking, this genetic disease may be the cause of the multiple aneurysms in this patient.- - - - - - - - - - ranking = 1keywords = soft (Clic here for more details about this article) |
9/83. Endovascular repair of radiation-induced bilateral common carotid artery stenosis and pseudoaneurysms: a case report.BACKGROUND: radiation-induced damage to small and medium-sized vessels has been observed in both animals and humans. Changes may appear in the immediate postradiation period or many years later. In this case, we report an unusual presentation of bilateral radiation-induced carotid artery stenoses associated with pseudoaneurysms, and a previously unreported application of a recently established treatment. CASE DESCRIPTION: A 72-year-old African-American male presented with recurrent right hemispheric transient ischemic attacks (TIA) and neck pain. Thirteen years previously, the patient had received radiation therapy for laryngeal carcinoma. Diagnostic carotid angiography demonstrated moderate radiation-induced bilateral carotid artery stenosis and associated common carotid pseudoaneurysms. The patient was treated with bilateral endovascular stents and electrolytically detachable coils in staged procedures. At his most recent follow-up, there is no evidence of re-stenosis and the patient remains asymptomatic. CONCLUSIONS: This case illustrates a novel and successful treatment for the endovascular repair of post-radiation bilateral carotid artery stenosis and pseudoaneurysms. In our practice, we have seen three such cases of radiation-induced vasculopathy. Therefore, patients with a previous history of radiation therapy for head and neck neoplasms merit cautious monitoring and judicious use of stents and secondary coils, when necessary.- - - - - - - - - - ranking = 0.70879095127248keywords = neoplasm (Clic here for more details about this article) |
10/83. A true aneurysm of the femoral artery in acromegaly.We report on an acromegalic patient who developed a true aneurysm in the right femoral artery. Plain computed tomography (CT) showed a soft tissue mass with low density adjacent to the right femoral artery. T1-weighted magnetic resonance (MR) images exhibited the lesion with moderate hypointensity peripherally, and hypointensity centrally. T2-weighted images showed the lesion to have areas of hypointensity, moderate hyperintensity, and marked hyperintensity. Surgery revealed an ectasia of the common femoral artery and a true aneurysm from the lateral femoral circumflex artery.- - - - - - - - - - ranking = 1keywords = soft (Clic here for more details about this article) |
