brachial artery aneurysms are rare but potentially limb threatening condition. the presented case here is a 52-year old male referred to the emergency department complaining a sudden onset and progressive pain with coldness of his right upper extremity during brushing. the right upper extremity was pulseless and three-dimensional computed tomography showed an aneurysm of the proximal right brac...

PURPOSE To determine the clinical effectiveness of parent artery occlusion of the carotid or vertebral artery by means of temporary proximal flow arrest and microcoils. METHODS Nineteen parent artery occlusions (15 carotid, four vertebral) were performed in 19 patients who successfully passed a balloon test occlusion. In these patients, endovascular occlusion of the carotid or vertebral arter...

BACKGROUND AND PURPOSE Information on the clinical and hemodynamic profile of intravenous tissue-type plasminogen activator nonresponders, at different locations of arterial occlusion, may improve the selection of candidates for rescue reperfusion therapies. Therefore, we aim to investigate predictors of failing intravenous tissue-type plasminogen activator therapy according to occluded vessel ...

OBJECTIVE The objective of this study was to evaluate the efficacy of hemostasis with patency in avoiding radial artery occlusion after transradial catheterization. BACKGROUND Radial artery occlusion is an infrequent but discouraging complication of transradial access. It is related to factors such as sheath to artery ratio and is less common in patients receiving heparin. Despite being clini...

Purpose. To report a case report of one patient suffering from retinal artery occlusion secondary to Buerger's disease, in order to raise awareness to this etiology in the differential diagnosis of retinal artery occlusion. Methods. A retrospective case report of a patient with retinal artery occlusion secondary to Buerger's disease. Data retrieved from the medical records included exposure, co...

Acute mesenteric ischemia is a rare cause of abdominal pain with a very high mortality rate. Vague presentation and often misleading clinical findings make the diagnosis elusive. Here, a unique case of complete superior mesenteric artery occlusion further complicated by basilar artery occlusion is illustrated.

Dear Editor, Retinal artery occlusion (RAO) is characterized by attenuated arterioles and ischemic retinal opacity, which suggest retinal infarction. Branch RAO (BRAO) has a more favorable prognosis than central RAO (CRAO). CRAO and BRAO can be differentiated based on the isch-emic retinal opacity area, location of the attenuated vessels , and a cherry-red spot [1]. However, we encountered a ca...

OBJECTIVES To screen differentially expressed genes of different days after cerebral artery occlusion and drug treatment, and identify related small drug molecules. MATERIALS AND METHODS The gene expression profile GSE35338 of cerebral artery occlusion was downloaded from Gene Expression Omnibus database, including a total of 14 samples. 5 samples are 1 day after cerebral artery occlusion (co...

OBJECTIVES RNF213 p.R4810K was identified as a susceptibility variant for moyamoya disease in Asia and non-moyamoya intracranial artery stenosis/occlusion disease in Japan and Korea recently. The occurrence of this variant was evaluated in patients with non-moyamoya intracranial artery stenosis/occlusion disease in China. METHODS Two study populations were used in this study. One was recruite...

Mortality following permanent occlusion of both common carotid arteries decreases as the time between the first and second occlusions increases in Fischer 344 rats. Our goal was to examine the possibility that collaterals develop after unilateral carotid artery occlusion. During temporary occlusion of both carotid arteries in nine ketamine-anesthetized male rats, mean +/- SEM blood flow in both...
