1/30. Peripheral arterial involvement in neurofibromatosis type 1--a case report.Neurofibromatosis is a dominantly inherited, progressive, generalized dysplasia of mesodermal and neuroectodermal tissues. Vascular lesions associated with neurofibromatosis type 1 (NF-1) are mainly characterized by stenosis, occlusion, aneurysm, pseudoaneurysm, and rupture or fistula formation of small, medium, and large-sized arteries. The authors hereby present a rare case of NF-1 with bilateral aneurysms and large pseudoaneurysms of the femoral and popliteal arteries and occlusion of the left superficial femoral artery.- - - - - - - - - - ranking = 1keywords = pseudoaneurysm, aneurysm (Clic here for more details about this article) |
2/30. Behcet's disease: endovascular management of a ruptured peripheral arterial aneurysm.Traditionally, bypass grafts are at a high risk for thrombosis or anastomotic degeneration in patients with Behcet's disease. We report the successful deployment of a vein-covered stent across the neck of a ruptured peripheral arterial aneurysm, via a remote site access, with intermediate-term follow-up. Covered stents may represent an attractive alternative to open surgical bypass for the management of aneurysms in patients with Behcet's disease.- - - - - - - - - - ranking = 0.48748168975152keywords = aneurysm (Clic here for more details about this article) |
3/30. A case of segmental mediolytic arteriopathy involving both intracranial and intraabdominal arteries.Segmental mediolytic arteriopathy (SMA) is an uncommon nonatherosclerotic and nonvasculitic arteriopathy. This disease is characterized by lytic degeneration of the arterial media, intramural dissection and thrombosed or ruptured aneurysm. SMA mainly involves the intraabdominal arterial system, resulting in intraabdominal and retroperitoneal hemorrhage. However, only a few cases of SMA with involvement of intracranial arteries have been reported. Here, we present a case of SMA developing subarachnoid hemorrhage due to dissection of the internal carotid and vertebral arteries. This patient was a 48-year-old male who died 13 days after admission for sudden loss of consciousness. Computed tomography showed subarachnoid hemorrhage. At autopsy, the affected vessels included the right vertebral, left internal carotid, superior mesenteric, bilateral renal and left external iliac arteries. Histopathologically, the arteries showed segmental lytic degeneration and disappearance of medial smooth muscle cells, medial dissection and formation of pseudo-aneurysms, the wall of which consisted of a thin membrane of the adventitia. These histopathological features mimicked an entire wall dissection type of intracranial dissecting aneurysm, which exclusively affects the vertebro-basilar system. Thus, SMA should be considered a possible underlying disease in patients with spontaneous dissection of intracranial arteries.- - - - - - - - - - ranking = 0.24374084487576keywords = aneurysm (Clic here for more details about this article) |
4/30. Paravisceral aortic thrombus as a source of peripheral embolization--report of three cases and review of the literature.Spontaneous embolization resulting in peripheral arterial occlusion remains a significant cause of morbidity and limb loss. Accurate localization and correction of the embolic source is paramount for the prevention of further episodes and for the preservation of long-term patency and limb salvage. Common well-recognized embolic sources include intracardiac thrombus or myxoma, and thrombus within arterial aneurysms or complex atherosclerotic plaques. Less common is thrombus arising de novo in an otherwise normal aorta, possibly as a result of prior trauma, occult arteriopathy, and/or hypercoagulability. Reported herein are three cases of peripheral or mesenteric embolization arising from large thrombi within the visceral aortic segment, with minimal evidence for atherosclerosis or other aortic pathology. Each patient was treated with visceral aortic thrombectomy using a direct surgical approach.- - - - - - - - - - ranking = 0.081246948291921keywords = aneurysm (Clic here for more details about this article) |
5/30. Peripheral aneurysm rupture in a patient with inactive systemic lupus erythematosus.We describe a patient with inactive systemic lupus erythematosus (SLE) presenting with sudden haemothorax, due to a ruptured internal mammary artery (IMA) aneurysm 7 years after the corticosteroid treatment was terminated. The unusual imaging findings and the treatment with embolization are discussed with a view to the role of a regular vascular screening in this patient group.- - - - - - - - - - ranking = 0.4062347414596keywords = aneurysm (Clic here for more details about this article) |
6/30. Balloon-assisted ultrasound-guided direct percutaneous embolization of a peripheral pseudoaneurysm with n-butyl cyanoacrylate.We report the ultrasound-guided direct percutaneous injection of n-butyl cyanoacrylate to embolize an iatrogenic peripheral pseudoaneurysm secondary in a 33-year-old patient undergoing hemodialysis. We protected the parent artery with inflation of an angioplasty balloon across the neck during the cyanoacrylate injection. Complete occlusion of the pseudoaneurysm was achieved without ischemic complication.- - - - - - - - - - ranking = 2.5125183102485keywords = pseudoaneurysm, aneurysm (Clic here for more details about this article) |
7/30. Segmental mediolytic arteriopathy involving celiac to splenic and left renal arteries.A 46-year-old man presented with a huge splenic artery dissecting aneurysm that had been incidentally found and was successfully resected before rupture. The histopathologic findings were compatible with segmental mediolytic arteriopathy (SMA). Simultaneous involvement of the left renal and right common iliac artery was observed. The patient was also found to have an adrenocortical adenoma, gastrointestinal stromal tumor, hepatocellular carcinoma and schizophrenia. The relationship between SMA and other accompanying diseases was discussed.- - - - - - - - - - ranking = 0.081246948291921keywords = aneurysm (Clic here for more details about this article) |
8/30. Clinical utility of rapid prescreening magnetic resonance angiography of peripheral vascular disease prior to cardiac catheterization.PURPOSE: The presence of peripheral vascular disease, in particular iliofemoral disease, is responsible in part for vascular complications from femoral artery cannulation. We investigated whether prescreening for vascular obstructions with magnetic resonance angiography (MRA) in high-risk patients with peripheral vascular disease (PVD) would provide useful information to angiographers seeking to improve the safety and efficiency of femoral artery access at cardiac catheterization. methods: Twelve consecutive patients with known or suspected PVD underwent contrast-enhanced, aorto-iliofemoral MRA using a real-time BolusTrak technique. Contrast-to-noise ratios for each patient were calculated. The cardiac angiographer reviewed the MRA prior to catheterization and selected an access site. The patients' subsequent clinical course was evaluated, and a postprocedure questionnaire was completed by the angiographer to define the value of the prescreening MRA. RESULTS: No significant vascular complications occurred in these patients as defined by failure of initially chosen access site, arterial dissection, limb ischemia, pseudoaneurysm formation, hemorrhage (including retroperitoneal hematoma), or need for blood transfusion or emergency vascular surgical repair. Statistical frequency analysis of the responses in the postprocedure questionnaire demonstrated that the MR data were clinically valuable in (1) influencing the initial choice of access site; (2) influencing technical alterations to the standard access; and, (3) enhancing confidence in the selection of access site. CONCLUSIONS: MRA prescreening in patients with PVD is an effective, novel adjunct to cardiac catheterization in selected patients that improves physician confidence and influences technical choices during coronary angiography from the femoral artery approach.- - - - - - - - - - ranking = 0.41875305170808keywords = pseudoaneurysm, aneurysm (Clic here for more details about this article) |
9/30. Cannulation injury of the radial artery: diagnosis and treatment algorithm.Cannulation of the radial artery can result in complications ranging from arterial thrombosis, arterial aneurysm, compartment syndrome, infection, nerve injury and skin necrosis to possible thumb or even hand necrosis if not recognized and treated early. The anatomy of the radial artery, the diagnosis of injury, and a treatment algorithm are presented so that potential devastating hand complications can be avoided.- - - - - - - - - - ranking = 0.081246948291921keywords = aneurysm (Clic here for more details about this article) |
10/30. time for a new classification of femoral artery aneurysm?It has been over 30 years now since the original classification of femoral artery aneurysms by Darning and Cutler to type 1 and 2. We have demonstrated in a case report that it is time for amendment of this classification. Isolated profunda aneurysm do exist as separate entity, and they can be managed by complete exclusion from the circulation provided the presence of patent superficial femoral artery and good runoff circulation, without any ill effects.- - - - - - - - - - ranking = 0.48748168975152keywords = aneurysm (Clic here for more details about this article) |
