1/136. subclavian steal syndrome and flow-related aneurysm. Another reason to treat.A 48-year-old woman presented with a symptomatic right subclavian steal syndrome due to proximal subclavian artery stenosis. Anatomically the innominate artery was absent. collateral circulation followed the vertebro-vertebral pathway with reversal of blood flow in the ipsilateral vertebral artery. There was also multiple dilated intervertebral collaterals and an associated saccular aneurysm on one of them. Surgical carotid-subclavian transposition permitted relief of clinical symptoms, disappearance of collateral circulation and subtotal regression of the aneurysm. This spontaneous evolution confirmed the role of high-flow in the pathogenesis of some aneurysms and the habitually good prognosis of flow-related aneurysms with correction of the cause. Arteriography still appears essential in diagnosis, pretherapeutic assessment and sometimes post-treatment evaluation in subclavian steal syndrome.- - - - - - - - - - ranking = 1keywords = essential (Clic here for more details about this article) |
2/136. 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 = essential (Clic here for more details about this article) |
3/136. Polyarthritis nodosa with mesenteric aneurysms demonstrated by angiography: report of a case and successful treatment of the patient with prednisolone and cyclophosphamide.polyarteritis nodosa is a necrotizing angitis that predominantly affects small and medium-sized arteries. The prognosis of untreated polyarteritis nodosa is very poor. Since symptoms are diverse and no serologic test is specific for polyarteritis nodosa, the diagnosis is difficult and often delayed. We describe a patient with polyarteritis nodosa who had gastrointestinal involvement with multiple aneurysms of the inferior mesenteric artery; only abdominal angiography provided a conclusive diagnosis. Alleviation of symptoms and regression of aneurysms were observed after combination therapy of an immunosuppressive agent, cyclophosphamide, and prednisolone. We emphasize the importance of early diagnosis by angiography and aggressive therapy in patients in whom physical signs indicating definite polyarteritis nodosa are not present.- - - - - - - - - - ranking = 124577.76661282keywords = polyarteritis, polyarteritis nodosa, nodosa, arteritis, necrotizing (Clic here for more details about this article) |
4/136. Renal angiogram abnormalities in a case of cutaneous polyarteritis nodosa.The existence of a limited cutaneous form of polyarteritis nodosa remains controversial. It has been characterized and contrasted with systemic polyarteritis nodosa by running a chronic course and having a relatively good long-term prognosis. We report a case with clinical features fitting the criteria for cutaneous polyarteritis nodosa but also showing evidence of associated renal aneurysms on selective visceral angiography. These findings suggest that the differentiation between systemic and cutaneous forms might be an oversimplification and we discuss the relationship between the two forms.- - - - - - - - - - ranking = 189090.48621878keywords = polyarteritis, polyarteritis nodosa, nodosa, arteritis (Clic here for more details about this article) |
5/136. Neutrophil and endothelial cell activation in the vasa vasorum in vasculo-Behcet disease.AIM: The aim of this study was to analyse the immunopathological mechanisms of vasculo-Behcet disease, which were also compared to cases of Takayasu's arteritis and inflammatory aneurysm to evaluate differences in inflammatory mechanisms. METHOD AND RESULTS: We reviewed six cases of vasculo-Behcet disease, four of Takayasu's arteritis and seven inflammatory aneurysms which underwent surgical repair. Immunohistochemical studies were performed on paraffin-embedded tissue using a labelled streptavidin-biotin method, as was in-situ hybridization for Epstein-Barr virus. Microscopically, neutrophils and lymphocytes accumulated around the vasa vasorum. neutrophils were prominent as compared to Takayasu's arteritis and inflammatory aneurysm. Elastic fibres were not severely destroyed. endothelial cells (ECs) of most vasa vasorum expressed HLA-DR. The number of vasa vasorum around which inflammatory infiltrating cells were observed in vasculo-Behcet disease was significantly greater than in inflammatory aneurysms and Takayasu's arteritis (P < 0.001). The cytokines IL-1alpha, TNF-beta and IFN-gamma were expressed in neutrophils and lymphocytes which were distributed around vasa vasorum, as well as neutrophils adherent to HLA-DR positive ECs. CONCLUSION: Our results suggest that vasculo-Behcet disease should be classified as a neutrophilic vasculitis targeting the vasa vasorum. aneurysm formation may be related to degeneration of arterial wall caused by inflammation of the vasa vasorum.- - - - - - - - - - ranking = 517.17598619492keywords = arteritis (Clic here for more details about this article) |
6/136. Giant aneurysm of the splenic artery--a case report.Giant aneurysms of the splenic artery larger than 10 cm are rare. The size of splenic aneurysms rarely exceeds 3 cm. Aneurysms that are often symptomatic because of their size must be treated rapidly before rupture. An etiologic and diagnostic evaluation with computed tomography and selective angiography of the visceral arteries is essential before treatment. Operative indication is imperative for these aneurysms. Their mass with portal compression and dense adhesions to adjacent organs allow only aneurysmal exclusion by proximal and distal ligation with preservation of the spleen. The control of the proximal splenic artery is often difficult, justifying the choice of the surgical access. A case of surgically treated giant splenic artery aneurysm associated with right benign renal lesion is presented with a review of the literature on this subject.- - - - - - - - - - ranking = 1keywords = essential (Clic here for more details about this article) |
7/136. Surgical repair of a solitary deep femoral arterial aneurysm: report of two cases.We report herein two cases of a solitary deep femoral arterial aneurysm that were successfully treated by aneurysmectomy and ligation of the deep femoral artery. The patients were a 69-year-old man and a 73-year-old man, both of whom presented with localized pain and a pulsatile mass in the femoral area showing rapid enlargement. ultrasonography and arteriography confirmed the diagnosis and revealed no evidence of aneurysm or occlusive disease in the other arteries. Aneurysmectomy and ligation of the deep femoral artery were performed, and no ischemic symptoms or thrombus developed postoperatively in either patient. Preoperative arteriography is essential to delineate not only the state of the aneurysm, but also that of the distal arterial tree. An emergency operation is also mandatory due to the rapid enlargement of this type of aneurysm, even if rupture occurs.- - - - - - - - - - ranking = 1keywords = essential (Clic here for more details about this article) |
8/136. aneurysm in the pulmonary trunk associated with atrial septal defect, a left coronary artery fistula to the pulmonary trunk, and valvular pulmonary stenosis.A 78-year-old woman with an aneurysm in the pulmonary trunk associated with an atrial septal defect, left anterior descending coronary artery fistula to the pulmonary trunk and valvular pulmonary stenosis is reported. The aneurysm showed gradual dilatation over 16 years and was successfully treated using aneurysmorrhaphy. Although there has been some controversy regarding the optimum management for a pulmonary artery aneurysm, surgical correction is thought to be essential for aneurysms associated with congenital cardiac anomalies because of the high incidence of rupture.- - - - - - - - - - ranking = 1keywords = essential (Clic here for more details about this article) |
9/136. A variant form of churg-strauss syndrome: initial temporal non-giant cell arteritis followed by asthma--is this a distinct clinicopathologic entity?The clinical manifestations of the classical vasculitis syndromes are extraordinarily heterogenous with considerable overlap among them. Recently, several cases of unusual presentation of the vasculitis syndromes have been reported. We describe a patient who initially manifested with temporal arteritis and Raynaud's phenomenon and subsequently developed bronchial asthma, ie, a case of an atypical form of churg-strauss syndrome (allergic angiitis and granulomatosis) and discuss whether this case is a distinct clinicopathological entity.- - - - - - - - - - ranking = 646.46998274364keywords = arteritis (Clic here for more details about this article) |
10/136. Angiographic features associated with antiphospholipid syndrome.We describe a case of primary antiphospholipid syndrome presenting with varied arterial abnormalities. patients with antiphospholipid syndrome commonly present with thrombotic problems, but there is a subgroup of patients who develop aneurysms with no evidence of vasculitis. This may represent part of the spectrum of the syndrome itself rather than an associated disease such as polyarteritis nodosa.- - - - - - - - - - ranking = 27012.926602683keywords = polyarteritis, polyarteritis nodosa, nodosa, arteritis (Clic here for more details about this article) |
