However, to date, no prior intrasaccular devices were available to treat GPTIAs, including the Food and Drug Administration-approved Woven EndoBridge device which could only accommodate aneurysms up to ∼11 mm in width.

They can be categorized into vein of Galen aneurysmal malformation (VGAM), pial arteriovenous fistula (PAVF), and dural arteriovenous fistula associated with dural sinus malformation (DAVF/DSM). We sought to review the clinical presentation, imaging characteristics, endovascular treatment (EVT), and outcomes of IAVS in infants presenting to a quaternary pediatric referral center over one decade.MethodsA retrospective review of a prospectively maintained database was performed of all infants diagnosed with IAVS between January 2011 and January 2021 in a quaternary pediatric referral center. For each patient, demographic data, clinical presentation, imaging findings, management strategies, and outcomes were reviewed and discussed.ResultsOver the study period, 38 consecutive infants were diagnosed with IAVS. Patients with VGAM (23/38, 60.5%) presented with congenital heart failure (CHF) (14/23), hydrocephalus (4/23), and seizures (2/23), and three patients were asymptomatic. Eighteen patients with VGAM underwent EVT. Among those, 13 patients (72.2%) were successfully treated with an angiographic cure and three patients (3/18, 17%) died. Patients with PAVF (9/38, 23.7%) presented with CHF (5/9), intracranial hemorrhage (2/9), and seizures (2/9), and all of them were successfully treated endovascularly. Patients with Type I DAVF/DSM (4/6, 66.6%) presented with mass effect (2/4), cerebral venous hypertension (1/4), CHF (1/4), and cerebrofacial venous metameric syndrome (1/4).

This study aimed to (1) quantify the enhancement in clot traction when using PFT as compared to the standard unsheathing technique (SUT) and (2) to evaluate the performance of PFT in new versus established users of the technique.MethodsOperators were divided between established PFT and SUT users. Each experiment was labeled according to the SR size, utilized technique, and operator experience. A three-dimensional-printed chamber with a clot simulant was used.

The median overall force to disengage the clot was 1.11 pounds for PFT and 0.70 pounds for SUT (an overall 59.1% increment with PFT; p < 0.001).

Moreover, posterior circulation aneurysms in kids tend to be larger in size, many of them being giant dissecting types, and treatment of them is often challenging. Treatment of giant dissecting aneurysms, especially involving the Basilar artery is difficult due to strategic location and haemodynamic factors. Use of reconstructive techniques viz. flow-diverters and braided stents is difficult in children because of the lack of standard protocol for use of antiplatelet therapy and the need for prolonged use of the same. Continuous growth of parent vessel is also suggested as a pitfall for the use of a flow diverter/ braided stent which has a fixed caliber. Carefully planned endovascular parent or feeder branch artery occlusion (FAO) is a time-tested method to achieve flow reversal or favourable flow modifications in an arterial segment harbouring dissecting aneurysm. Here, in this case report, we describe a case of a ruptured distal giant basilar artery dissecting aneurysm in a 10-year-old boy treated with flow diversion by FAO. The dominant left vertebral artery was occluded, thereby diverting flow from the right vertebral artery towards the left posterior inferior cerebellar artery and decreasing flow through the aneurysm.
