1/49. 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 (Clic here for more details about this article) |
2/49. 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 = 5keywords = vascular disease (Clic here for more details about this article) |
3/49. 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 = 1keywords = vascular disease (Clic here for more details about this article) |
4/49. 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 = 1keywords = vascular disease (Clic here for more details about this article) |
5/49. 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 = 1keywords = vascular disease (Clic here for more details about this article) |
6/49. renal artery stenosis and aneurysmatic dilatation of arteria carotis interna in tuberous sclerosis complex.hypertension in children with neurocutaneous disorders (phacomatoses) is a well-recognized complication of these diseases and the cause of hypertension is fairly specific within each group. In patients with neurofibromatosis, hypertension is mainly caused by renovascular disease, whereas in tuberous sclerosis (TSC) reasons for hypertension are renoparenchymal lesions, such as angiomyolipoma or cysts. We report on a girl with TSC and hypertension due to unilateral renal artery stenosis associated with aneurysmatic changes of internal carotid artery. This unusual combination of symptoms in our patient supports the importance of thorough and complete investigation of hypertension in children with phacomatoses.- - - - - - - - - - ranking = 1keywords = vascular disease (Clic here for more details about this article) |
7/49. Left renal vein aneurysm: imaging findings.A renal vein aneurysm is a rare vascular disease. To our knowledge, only six cases have been reported. We describe a 57-year-old woman with a left renal vein aneurysm diagnosed by a combination of ultrasonography, color Doppler ultrasonography, contrast-enhanced computed tomography, and magnetic resonance imaging.- - - - - - - - - - ranking = 1keywords = vascular disease (Clic here for more details about this article) |
8/49. Laparoscopic exclusion of a splenic artery aneurysm--a case report.splenic artery aneurysm is a rare but serious vascular disease. The mortality risk is 36% when one is ruptured. Surgical therapy has traditionally consisted in resection through a laparotomy. The authors' experience of a case of laparoscopic exclusion of a splenic artery aneurysm is reported. This surgical approach is simple, safe, and minimally invasive. This procedure should increase the indication for surgical treatment of a splenic artery aneurysm.- - - - - - - - - - ranking = 1keywords = vascular disease (Clic here for more details about this article) |
9/49. Delayed recognition of a vascular complication, carotid artery aneurysm, 60 years after operation for muscular torticollis. A case report.An extremely rare vascular complication, carotid artery aneurysm, developed 60 years after a torticollis operation. The patient's internal jugular vein was completely obstructed proximal to the subclavian vein. There was an associated incomplete obstruction of the ipsilateral common carotid artery on the right aspect of the neck--the site where resection of the whole sternocleidomastoid muscle had been performed when she was one year old. The patient had audible bruits over the right common carotid at the base of her neck but no signs of occlusive cerebrovascular disease. The diagnosis was made mainly with use of technetium radionuclide angiography. To the authors' knowledge, this is the first such report in the English or German literature.- - - - - - - - - - ranking = 1keywords = vascular disease (Clic here for more details about this article) |
10/49. Isolated extra-cranial internal carotid artery aneurysm in a young adult with Eale's disease.A young male patient, a known case of Eale's disease presented with a large isolated aneurysm of the extra-cranial part of internal carotid artery. Detailed investigation failed to establish the etiology of the aneurysm, and it is possible that the underlying pathology may be the same as that of Eale's disease. Eale's disease is an idiopathic vascular disease of the peripheral retina and we hypothesize that aneurysm in this patient may be associated with Eale's disease of the eye.- - - - - - - - - - ranking = 1keywords = vascular disease (Clic here for more details about this article) |
