Hybrid operation to revascularize long-segment occluded internal carotid artery prevent further ischemic events.

Purpose: The effects and complications of hybrid procedure (combined carotid endarterectomy and carotid stenting) to revascularize chronic long-segment occlusion of internal carotid artery (ICA) are currently unknown and the purpose of this study.

Methods: Sixty-five patients with long-segment occlusion of ICA were prospectively enrolled and divided into two groups of revascularization with hybrid operation (n = 30) and medication group (n = 35), and clinical and angiographic data were analyzed.

Results: The duration from symptom onset to revascularization ranged 17-120 days (mean 40.

Endovascular Recanalization of Occluded Dural Sinus in Patient with Dural Arteriovenous Fistulas: Case Report and Literature Review.

Background: Symptomatic sinus occlusion complicated with dural arteriovenous fistulas (dAVFs) can be treated successfully endovascularly. However, no studies have reported the use of endovascular transvenous approaches alone to recanalize the occluded sinuses for treatment of the involved dAVFs without stent deployment. In this study, we presented a 75-year-old man with occlusion of the transverse and sigmoid sinuses complicated with a dAVF.

Characteristics and Endovascular Management of the Posterior Cerebral Artery Anterior Temporal Branch Aneurysms.

Purpose: To investigate characteristics of the posterior cerebral artery anterior temporal branch aneurysm and the safety and efficacy of endovascular management.

Materials And Methods: A total of 6 patients with anterior temporal branch aneurysms were enrolled. All 6 patients had concurrent occlusion of the ipsilateral anterior circulating arteries.

Endovascular Treatment of Intracranial Aneurysms Concomitant with Severe Adjacent Atherosclerotic Stenosis.

Purpose: To investigate the effect and safety of endovascular treatment of intracranial aneurysms concomitant with severe adjacent atherosclerotic stenosis.

Materials And Methods: Twenty-six patients with aneurysms and adjacent stenosis were prospectively enrolled. The characteristics of the aneurysm, parent artery, atherosclerotic stenosis and endovascular treatment methods were analyzed.

Intravenous administration of tirofiban versus loading dose of oral clopidogrel for preventing thromboembolism in stent-assisted coiling of intracranial aneurysms.
