Endovascular Treatment of "Donut-Shaped" Aneurysm-A Case Series.

: Partially thrombosed aneurysms represent a subset primarily found within large and giant aneurysms. The presence of an intraluminal thrombus can cause an aneurysm to present in different shapes upon angiographic examination. We present a series of five cases of "donut-shaped" aneurysms observed over the past decade at the Clinic for Neurosurgery in the University Clinical Centre of Serbia.

Successful Hybrid Approach Treatment of a Large Persistent Sciatic Artery Aneurysm-A Case Report.

: Persistent sciatic artery (PSA) is a rare congenital vascular anomaly that is often asymptomatic, but can be associated with aneurysm formation and potential complications, such as thromboembolism or aneurysm rupture in some cases. We present a case of a 75-year-old woman with a symptomatic thrombus-containing aneurysm of the left PSA. : The treatment of the PSA aneurysm involved a successful hybrid approach, which included open surgical bypass and endovascular embolization.

Atrial fibrillation is associated with poor long-term outcome after mechanical thrombectomy for anterior large vessel occlusion stroke.

Objectives: Atrial fibrillation (AF) is one of the leading causes of acute ischemic stroke (AIS). The aim of our study was to determine the influence of AF on the long-term outcome of patients with AIS due to anterior circulation large vessel occlusion (LVO) treated with mechanical thrombectomy (MT).

Methods: Our study included 127 consecutive patients with AIS due to anterior LVO who underwent MT between January 2018 and March 2020.

Influence of Thrombocytopenia on the Outcome of Mechanical Thrombectomy in Patients with Acute Ischemic Stroke.

Objectives: Mechanical thrombectomy (MT) has become leading treatment option for acute ischemic stroke (AIS) due to large vessels occlusion (LVO). Platelet counts may affect outcome in patients with AIS or transient ischemic attack. The aim of our study was to determine the influence of thrombocytopenia on the safety and efficacy of MT in patients with AIS due to anterior circulation LVO.

Developmental Venous Anomaly Serving as a Draining Vein of Brain Arteriovenous Malformation.

Developmental venous anomalies are cerebral vascular malformations that present normal venous drainage of cerebral tissue. With increased and accessible usage of modern diagnostic tools, they are now one of the most commonly diagnosed cerebral vascular malformations. Although developmental venous anomalies are considered to be benign lesions, association with arteriovenous malformation renders malignant potential to this combined pathology.
