Snowballing Technique for High Flow Arteriovenous Fistula: A Technical Note.

A novel endovascular technique to occlude high flow direct arteriovenous fistulae is presented, where the distal tip of the microcatheter acts as a nucleus that the operator can grow a plug from a liquid embolic agent. Its advantages (such as cost-saving and distal reachability), disadvantages (such as embolic material instability), and technique are discussed.

Isolated hemorrhagic arterialized DVAs: revisiting symptomatic DVAs.

We aim to present here a small case series of symptomatic isolated hemorrhagic arterialized developmental venous anomalies (sDVAs) with a larger goal of revisiting the classification based on patho-mechanisms plus emphasizing angiographic features coupled with CT and MRI. Typically, DVA is an incidental and silent abnormality on neuroimaging. Understanding its morphology in terms of arterialization and relationship with other entities is crucial for management.

Accuracy of Canadian CT head rule in predicting positive findings on CT of the head of patients after mild head injury in a large trauma centre in Saudi Arabia.

Background: Investigation of unjustified computed tomography (CT) scan in patients with minor head injury is lacking in Saudi Arabia. The purpose of the study was to evaluate the compliance and effectiveness of the Canadian computed tomography head rule (CCHR) in our emergency department (ED) and trauma centre and also to reduce the number of unjustified CT studies of the head in the centre.

Methods: A retrospective study of 368 ED patients with minor head injury was conducted.

Neurointerventional participation in craniopagus separation.

Craniopagus-type conjoined twins (joined at the head) are exceedingly rare. Separation of craniopagus conjoined twins is a challenging task mainly owing to complex vascular anatomy and limited experience with this disorder. Modern neuroimaging techniques including digital subtraction angiography can be used to preoperatively assess the cerebral vascular system.

Flow-diverter stent for the treatment of a non-origin posterior inferior cerebellar artery aneurysm. A case report.

We describe the case of a 44-year old man with a ruptured wide-necked non-origin aneurysm of the posterior inferior cerebellar artery successfully treated with placement of a low porosity stent. To our knowledge, there are no cases in the literature of a non-origin posterior inferior cerebellar artery aneurysm treated with a flow-diverter stent.
