AbstractBlister aneurysms are intracranial arterial lesions originating at nonbranching sites of the dorsal supraclinoid internal carotid artery and basilar artery.1 Among different treatment options, the use of flow-diverting devices is gaining popularity and has the potential for becoming the standard of care.2 Radiological evaluation of flow diverter braid expansion and vessel wall apposition during procedure has become useful in preventing life-threatening complications. Incomplete coverage of an aneurysm neck, kinking, or incomplete expansion and malapposition of a stent carries a significant risk for thromboembolic events.3 4

This paper is a case report of a young patient after a major head trauma causing multiple skull base fractures. The trauma occasioned pseudoaneurysm (PSA) from intracavernous C4 segment of left internal carotid artery (ICA) protruding in the sphenoidal sinus. After two months, two episodes of massive epistaxis occurred. Consequently, the post-traumatic PSA was treated, after carotid occlusion test, with flow-diverter stent positioning. A computed tomography angiography study performed in the following days showed complete resolution of the post-traumatic PSA lesion and ICA patency.

BackgroundFlow diversion is an important tool for treatment of cerebral aneurysms, particularly large and giant aneurysms. The Surpass flow diverter is a new system under evaluation in the USA.ObjectiveTo report our initial experience of 20 cases with the Surpass flow diverter to demonstrate its basic properties, the required triaxial delivery platform, and the methodologies used to deploy it during treatment of large internal carotid artery (ICA) aneurysmsMethodsTwenty patients with ICA aneurysms ≥10 mm with ≥4 mm neck treated as part of the Surpass IntraCranial Aneurysm Embolization System Pivotal Trial (the SCENT trial; Stryker) were included. Details of patient demographics, aneurysm characteristics, and technical procedures were collected.ResultsTwenty patients (mean age 63.3±1.3 years; range 51–72) with 20 unruptured aneurysms (mean size 13.4±0.9 mm; range 10–21 mm) were treated. For proximal access, 60% of cases had aortic arch ≥grade II, 55% had significant cervical ICA tortuosity, and 60% had cavernous ICA ≥grade II. The Surpass device was implanted in 19/20 (95%) cases. Of 19 cases, a single device was used in 18 cases (95%) and 2 devices in only 1 case (5%). Balloon angioplasty was performed in 8/19 cases (42%). Complete aneurysm neck coverage and adequate vessel wall apposition was obtained in all 19 cases.ConclusionsSurpass is a next-generation flow diverter with unique device-specific and delivery-specific features compared with clinically available endoluminal flow diverters. Our initial experience demonstrates a favorable technical profile in treatment of large and giant ICA aneurysms.Trial registration numberNCT01716117.

Abstract Background Intra-arterial treatment of aneurysms by redirecting blood flow is a newer method. The redirection is based on a significantly more densely braided wire stent. The stent wall keeps the blood in the lumen of the stent and slows down the turbulent flow in the aneurysms. Stagnation of blood in the aneurysm sac leads to the formation of thrombus and subsequent exclusion of the aneurysm from the circulation. The aim of the study was to evaluate flow diverter device Pipeline for broad neck and giant aneurysm treatment. Methods Fifteen patients with discovered aneurysm of the internal carotid artery were treated between November 2010 and February 2014. The majority of aneurysms of the internal carotid artery were located intradural at the ophthalmic part of the artery. The patients were treated using a flow diverter device Pipeline, which was placed over the aneurysm neck. Treatment success was assessed clinically and angiographically using O’Kelly Marotta scale. Results Control angiography immediately after the release of the stent showed stagnation of the blood flow in the aneurysm sac. In none of the patients procedural and periprocedural complications were observed. 6 months after the procedure, control CT or MR angiography showed in almost all cases exclusion of the aneurysm from the circulation and normal blood flow in the treated artery. Neurological status six months after the procedure was normal in all patients. Conclusions Treatment of aneurysms with flow diverter Pipeline device is a safe and significantly less time consuming method in comparison with standard techniques. This new method is a promising approach in treatment of broad neck aneurysms.
