1/201. Mucoid degeneration of the brachial artery: case report and a review of literature.Cystic adventitial disease (CAD) is a rare cause of intermittent claudication, occurring in approximately 1:1200 claudicants or 1:1000 of those undergoing arteriography. It is most often described in the popliteal artery and is characterised by a mucinous cyst located in the adventitia of the artery, the contents of which resemble those of a ganglion. The origins of adventitial cysts are unknown, but connections to adjacent synovial spaces have been identified, suggesting that the cyst is a variant of a ganglion. In this report, we discuss a rare case of severe mucoid degeneration of the intima and media in a 67-year-old Saudi male patient. The patient presented with a saccular aneurysm of his right "mid-arm" brachial artery and critical ischemia of his right hand from distal embolisation.- - - - - - - - - - ranking = 1keywords = aneurysm (Clic here for more details about this article) |
2/201. Failure of a saphenous vein extracranial-intracranial bypass graft to protect against bilateral middle cerebral artery ischemia after carotid artery occlusion: case report.OBJECTIVE AND IMPORTANCE: We present the case of a patient who experienced bilateral middle cerebral artery infarctions after Hunterian ligation and trapping of a ruptured right cavernous aneurysm, despite a high-flow extracranial-intracranial bypass. This is a rare complication, and it highlights the need for further refinements in our understanding of the hemodynamic insufficiency created by major vessel sacrifice. CLINICAL PRESENTATION: The patient was a 59-year-old woman who experienced multiple episodes of massive epistaxis before undergoing angiography, which revealed left internal carotid artery occlusion and an irregular right cavernous aneurysm. The patient was then transferred to our center for treatment. The patient was neurologically intact at presentation, and her epistaxis was controlled by nasal packing. INTERVENTION: The patient underwent an extracranial-intracranial bypass from the external carotid artery to the M2 segment of the right middle cerebral artery, followed by trapping of the aneurysm. Despite evidence of graft patency, the patient experienced bilateral middle cerebral artery distribution infarctions after surgery. CONCLUSION: Although extracranial-intracranial bypasses protect the majority of patients who undergo carotid artery ligation from ischemic complications, this case demonstrates that hemodynamic insufficiency can occur even with a high-flow saphenous vein graft. Better ways to quantitate the hemodynamic needs of the brain after major vessel sacrifice may facilitate matching of the revascularization strategy to the specific needs of each patient, thus further reducing the likelihood of ischemic complications.- - - - - - - - - - ranking = 3keywords = aneurysm (Clic here for more details about this article) |
3/201. Thoracoabdominal aortic aneurysm in Cogan's syndrome.Cogan's syndrome is an autoimmune disease of unknown etiology, clinically manifested as non-syphilitic interstitial keratitis and audiovestibular symptoms. Increasing evidence suggests that Cogan's may be a systemic vasculitis. In this report, we review the vascular manifestations of Cogan's syndrome and report two cases of thoracoabdominal aortic aneurysm in patients with this disorder.- - - - - - - - - - ranking = 5keywords = aneurysm (Clic here for more details about this article) |
4/201. Successful transcatheter embolization of a pancreaticoduodenal artery aneurysm in association with celiac axis occlusion: a case report.We report a case of a pancreaticoduodenal artery (PDA) aneurysm in association with celiac axis occlusion. A 54 year-old female complaining of abrupt onset of abdominal pain was admitted to our hospital. On admission, abdominal CT examination revealed a hematoma in the retroperitoneal space. Selective superior mesenteric artery (SMA) angiography disclosed an aneurysm in the anterior inferior pancreaticoduodenal artery (AIPDA). The celiac axis was occluded and blood was flowing to the liver and spleen via the enlarged pancreaticoduodenal arcade from the SMA. Transcatheter embolization of the aneurysm was performed successfully. Up to 1996, there have been 37 reported cases of PDA aneurysm in association with celiac axis stenosis or occlusion, including this one. Transcatheter embolization was performed successfully in only 5 of these cases. The formation of this type of PDA aneurysm is thought to be a result of the increased blood flow in the pancreaticoduodenal arcade due to celiac axis stenosis or occlusion. The transcatheter embolization performed in our report produced a far greater blood flow, which may lead to further aneurysmal formation. Careful follow-up is therefore necessary.- - - - - - - - - - ranking = 10keywords = aneurysm (Clic here for more details about this article) |
5/201. Unusual complications in an inflammatory abdominal aortic aneurysm.An unusual case of an inflammatory abdominal aortic aneurysm (IAAA) associated with coronary aneurysms and pathological fracture of the adjacent lumbar vertebrae. The associated coronary lesions in cases of IAAA are usually occlusions. In the present case, it was concluded that a possible cause of the coronary aneurysm was coronary arteritis and the etiology of the pathological fracture of the lumbar vertebrae was occlusion of the lumbar penetrating arteries due to vasculitis resulting in aseptic necrosis. Inflammatory AAA can be associated with aneurysms in addition to occlusive disease in systemic arteries. The preoperative evaluation of systemic arterial lesions and the function of systemic organs is essential.- - - - - - - - - - ranking = 8keywords = aneurysm (Clic here for more details about this article) |
6/201. A subclavian artery aneurysm associated with aortitis syndrome.We performed surgery on a 61-year-old woman who had increasingly severe right shoulder pain and paresthesia in her right upper extremity as a result of a large right subclavian artery aneurysm. She had suffered from aortitis syndrome for 10 years for which she was treated with steroids and had multiple arterial lesions, including bilateral subclavian artery aneurysms, abdominal aortic aneurysm and obstruction of bilateral superficial femoral arteries. The right subclavian artery aneurysm measured 4 cm in diameter and rupture appeared imminent, prompting surgical therapy. Via the supraclavicular incision approach and additional partial sternotomy, the aneurysm was excluded and the brachiocephalic to right axillar arterial bypass was set up using an extended polytetrafluoroethylene graft. The patient recovered without complications and a subclavian artery aneurysm demonstrated by computed tomography was thrombosed 1 month after surgery. In conclusion, we recommend the exclusion technique to treat subclavian artery aneurysms in cases in which aneurysmectomy is likely to injure adjacent veins and nerves.- - - - - - - - - - ranking = 12keywords = aneurysm (Clic here for more details about this article) |
7/201. Thoracoabdominal aortic aneurysm combined with aortic occlusion.The case of a 73-year-old woman with aneurysms of the thoracoabdominal aorta and distal arch, combined with aortic occlusion, is reported. Cannulation from the femoral artery was not possible because of the aortic occlusion. blood supply to the abdominal viscera and lower extremities was achieved only by selective perfusion from the celiac artery, superior mesenteric artery, and bilateral renal arteries. A unique choice of selective perfusion for distal circulatory support is described.- - - - - - - - - - ranking = 5keywords = aneurysm (Clic here for more details about this article) |
8/201. pulmonary artery compression by a giant aortocoronary vein graft aneurysm.Late failure of saphenous vein aortocoronary bypass grafts is predominantly due to vein graft atherosclerotic disease. Rarely, saphenous vein aortocoronary bypass grafts undergo aneurysmal degeneration. We report a case of a giant true aneurysm of a saphenous vein aortocoronary bypass graft producing right heart failure from main pulmonary artery compression.- - - - - - - - - - ranking = 6keywords = aneurysm (Clic here for more details about this article) |
9/201. A narrow-waisted abdominal aortic aneurysm complicating endovascular repair.PURPOSE: To present a case in which a narrow waist in an abdominal aortic aneurysm (AAA) complicated endovascular repair using a modular bifurcated stent-graft. methods AND RESULTS: A 68-year-old man underwent endovascular repair of a 5.9-cm asymptomatic AAA with a self-expanding modular bifurcated stent-graft. After insertion and deployment of the stent-graft, the intraoperative completion angiogram disclosed unexpected incomplete deployment of the contralateral iliac limb due to a narrow waist in the aortic aneurysm. Subsequent angioplasty did not increase iliac stent-graft diameter. At follow-up, a tapered course of the contralateral iliac leg persisted, without hemodynamic significance. CONCLUSIONS: A narrow waist in an AAA may be considered an additional important anatomical characteristic in assessing suitability for endovascular repair.- - - - - - - - - - ranking = 6keywords = aneurysm (Clic here for more details about this article) |
10/201. Endovascular stentgraft infection--a life-threatening complication.The implantation of covered stents or stentgrafts has increased greatly in the last few years for the endovascular reconstruction of arterial aneurysms. We report of three patients experiencing severe septic complications after stentgraft implantation. Endovascular stentgraft infection is a serious complication with high morbidity and mortality. General antibiotic prophylaxis seems to be indicated when implanting stentgrafts.- - - - - - - - - - ranking = 1keywords = aneurysm (Clic here for more details about this article) |
