1/97. Retinal venous macroaneurysm associated with premacular hemorrhage.To report an unusual association of a retinal venous macroaneurysm with premacular hemorrhage in a 50-year-old man, using a case report method. The patient exhibited a dense premacular hemorrhage in the left eye. fluorescein angiography demonstrated that the source of bleeding was an isolated retinal venous macroaneurysm. The anterior surface of the hematoma was opened with an argon green laser, resulting in rapid clearing of the premacular hemorrhage and improvement in vision. Treatment of the retina surrounding the macroaneurysm to prevent recurrence of bleeding was ineffective to achieve occlusion of the lesion. No recurrent hemorrhage occurred during the observation period. Retinal venous macroaneurysm, a quite rare condition, may be complicated by premacular hemorrhage. argon green laser may be useful in treating such hemorrhage. Hemorrhagic detachment of the internal limiting membrane or subhyaloid hemorrhage in the macula may occur after retinal vessel rupture with physical exertion (Valsalva retinopathy) or in retinal vascular diseases, such as proliferative diabetic retinopathy, and retinal arterial macroaneurysm. Arterial macroaneurysms are a common, well-described retinal vascular disorder. In contrast to retinal arterial macroaneurysms, retinal venous macroaneurysms are quite rare. In this article we describe a patient who presented with premacular hemorrhage that was caused by a retinal venous macroaneurysm. The hematoma and the macroaneurysm were treated with argon green laser.- - - - - - - - - - ranking = 1keywords = vascular disease, diabetic (Clic here for more details about this article) |
2/97. A case of vasculo-Behcet's syndrome.A case of Behcet's syndrome with vascular complications is presented. This case had a familial occurrence of Behcet's syndrome. His vascular complications were deep vein thrombophlebitis of both legs, aneurysms of the left common iliac artery and the left femoral artery and the occlusion of the left subclavian artery. He was successfully operated on for the aneurysms. This paper discusses the problems accompanying the aneurysm of Behcet's syndrome. The authors pointed out that the subclavian steal syndrome may be diagnosed as neuro-Behet's syndrome and stressed the importance of vascular survay in Behcet's syndrome when the patient complaints of thrombophlebitis.- - - - - - - - - - ranking = 34.345754122415keywords = vascular complication (Clic here for more details about this article) |
3/97. Endovascular treatment of noncarotid extracranial cerebrovascular disease.The last two decades have witnessed a growing application of endovascular techniques for the treatment of atherosclerotic disease of the extracranial vertebral arteries, subclavian arteries, and brachiocephalic artery. Beginning with simple balloon angioplasty, these minimally invasive techniques have now progressed to the use of stent-supported angioplasty. Stent-supported angioplasty is currently providing a therapeutic alternative to traditional methods of open surgery for revascularization of these vessels and increasing the therapeutic options available for patients who have failed maximal medical therapy. Additionally, endovascular techniques are also being used successfully to treat a variety of nonatherosclerotic diseases affecting the noncarotid extacranial arteries, such as inflammatory, radiation, and anastomotic-graft strictures; acute intimal dissection; traumatic and spontaneous arteriovenous fistulas; and aneurysms or pseudoaneurysms. Continued innovation and refinement of endovascular devices and techniques will inevitably improve technical success rates, reduce procedure-related complications, and broaden the endovascular therapeutic spectrum for extracranial cerebrovascular disease.- - - - - - - - - - ranking = 4.7149388309278keywords = vascular disease (Clic here for more details about this article) |
4/97. De novo renal artery aneurysm presenting 6 years after transplantation: a complication of recurrent arterial stenosis?Pseudoaneurysms represent a well-recognized vascular complication of renal transplantation, but true aneurysms involving the donor renal artery have not been described. We report a patient who had a de novo aneurysm of the donor renal artery 6 years after receiving a cadaveric renal transplant from a child. The aneurysm was repaired successfully, and allograft function was preserved. Histologic evidence confirmed that the lesion was a true aneurysm. Given the potential for graft loss associated with complications of unrepaired aneurysms, we believe that the presence of a true aneurysm in a donor renal artery represents an indication for repair.- - - - - - - - - - ranking = 17.172877061208keywords = vascular complication (Clic here for more details about this article) |
5/97. Cavernous haemangioma of the retina and optic disc. A report of three cases and a review of the literature.We report characteristics of three cases of cavernous haemangioma of the retina, bringing to 37 the number now reported in the available literature. This rare, benign, congenital malformation is non-progressive, usually unilateral, somewhat more frequent in women, and rarely a source of intraocular haemorrhage. The fluorescein angiographic features include a normal arterial and venous supply, extraordinarily slowed venous drainage, no arterio-venous shunting, no disturbances of vascular permeability, and no secondary retinal exudation. Almost always, isolated clusters of vascular globules with plasma/erythrocyte sedimentation surround the main body of the malformation. These findings differentiate the anomaly from other retinal vascular diseases. Therapeutic intervention is seldom necessary.- - - - - - - - - - ranking = 0.94298776618556keywords = vascular disease (Clic here for more details about this article) |
6/97. Surgical treatment for an idiopathic renal arteriovenous fistula with a large aneurysm.Interventional embolization is currently the first line treatment for arteriovenous fistulas; however, the efficacy of repeated embolization remains controversial. A case is reported of an idiopathic renal arteriovenous fistula with large aneurysmal dilatation treated by surgery following the failure of interventional embolization. A 42-year-old woman was admitted to Ichikawa General Hospital, japan, with gross hematuria containing many clots. Right renal arteriogram showed an aberrant vessel arising from the main trunk of the renal artery, which was followed by the formation of an aneurysm and rapidly ended in arteriovenous shunting. The aneurysm was approximately 35 mm in size. As interventional embolization had failed, surgical treatment including extracorporeal renal surgery was performed. Postoperative renal angiography revealed excellent renal function and beautiful vascular architecture. Although the indication for surgical treatment of renal vascular disease has decreased owing to the advancement of interventional techniques, there are still some risky cases for which surgical repair should be recommended.- - - - - - - - - - ranking = 0.94298776618556keywords = vascular disease (Clic here for more details about this article) |
7/97. uterine artery aneurysm mimicking pelvic sarcoma. A case report and review of literature. [email protected].We report a case of true uterine artery aneurysm in a 77-year-old diabetic woman, which was suspected radiologically as a pelvic sarcoma. The aneurysm was communicating with the atherosclerotic left uterine artery. Pelvic aneurysms carry the potential risk of massive intra-operative hemorrhage if the diagnosis was not established prior to operation.- - - - - - - - - - ranking = 0.057012233814436keywords = diabetic (Clic here for more details about this article) |
8/97. Idiopathic pulmonary artery aneurysm: digital subtraction pulmonary angiography grossly underestimates the size of the aneurysm.pulmonary artery aneurysm is a rare disease entity. The majority of cases are associated with congenital cardiovascular diseases, infection, and trauma; idiopathic pulmonary artery aneurysm is extremely rare. Although conventional and digital subtraction pulmonary angiography remains as the imaging modality of choice for the pulmonary vessels, it is invasive and sometimes may be inaccurate. With the advent of spiral computed tomographic angiography (CTA), pulmonary artery aneurysm can be diagnosed noninvasively and accurately. We report a case of a 68-year-old man with idiopathic pulmonary artery aneurysm of the descending branch of right pulmonary artery where the true caliber of the aneurysm was significantly underestimated in the digital subtraction pulmonary angiography. The literatures of this rare condition are reviewed with the emphasis on the application of CTA in this disease.- - - - - - - - - - ranking = 0.94298776618556keywords = vascular disease (Clic here for more details about this article) |
9/97. Local vascular complications after knee replacement: a review with illustrative case reports.The incidence of vascular complications after knee replacement is between 0.03% and 0.2%. These complications include acute ischaemia, thrombosis, haemorrhage, fistula and aneurysm formation. Vascular complications can be avoided by careful pre-operative selection. If doubt exists, a vascular opinion should be obtained before knee replacement. In the event of a vascular complication occurring, serious morbidity can be avoided by prompt diagnosis, investigation and specialist treatment.- - - - - - - - - - ranking = 103.03726236725keywords = vascular complication (Clic here for more details about this article) |
10/97. Endovascular interventions on persistent sciatic arteries.PURPOSE: To report our experience with interventional procedures used to treat complete and incomplete persistent sciatic arteries (PSA). case reports: Three female patients with PSAs displayed varying symptoms referable to this rare anatomical variant. In the first woman, a 1-year history of intermittent lower limb ischemia and an acute event prompted angiography, which demonstrated proximal occlusion of 2 crural vessels and a partially thrombosed sciatic artery aneurysm. To prevent further embolism, the aneurysm was excluded with a stent-graft. Endograft patency and aneurysm exclusion have been maintained up to 22 months. In a 41-year-old diabetic with chronic limb ischemia and digital gangrene, a flow-limiting stenosis of the sciatic artery was stented, restoring adequate pedal perfusion. The stent remained patent at the 18-month follow-up. The third patient suffered from a tumor-related pelvic hemorrhage originating from retrograde perfusion through the PSA, which had been ligated during previous surgery. Attempted embolization via a collateral connection between the incomplete PSA and the popliteal artery failed, and the patient died. CONCLUSIONS: Vasculopathies involving the sciatic artery are uncommon but may be amenable to interventional techniques, such as coil embolization and stent implantation. PSA aneurysm exclusion with a stent-graft may represent a new therapeutic alternative to standard surgery that obviates potential sciatic nerve damage, but the durability of the repair remains to be determined.- - - - - - - - - - ranking = 0.057012233814436keywords = diabetic (Clic here for more details about this article) |
