Type 1A endoleak detachable coil embolization after endovascular aneurysm sealing: Case report

IntroductionEndovascular aneurysm sealing (EVAS) with the Nellix system was introduced to reduce endovascular aneurysm repair (EVAR) perioperative complications, especially endoleaks. Herein we report a case of successful type 1A endoleak managed with detachable coils embolization after EVAS.Presentation of caseA 77-year-old male was referred for abdominal pain. The angio-CT scan confirmed the previous EVAS procedure and showed a type Is2 endoleak below the right renal artery resulting in a 2.5 cm aortic blister with contrast medium filling the space between the aortic wall and the endobags. The patient was considered unfit for conventional open surgery and an endovascular approach with coil embolization Concerto Helix Detachable Coil System was chosen under local anesthesia. After intervention, a complete abdominal pain regression was registered. The 12- month CT follow-up showed endoleak sealing and Nellix system stability.DiscussionEVAS has been associated to a high endoleaks and complications incidence when compared to EVAR. The EVAS different device concept led to a different endoleak classification and management. Endoleak management main options include the Nellix system explantation or the Nellix in Nellix application, however these are nearly always not applicable, respectively, due to the high surgical risk condition and the Nellix system availability, especially in emergent setting. Despite the use of coil embolization is controversial, this tool is off-the-shelf and leads to a disease resolution in most of patients without other surgical options.ConclusionProximal type Is2 embolization after EVAS is feasible with limited invasiveness.     

Ruptured renal angiomyolipoma treated by transcatheter arterial embolization: report of two cases

We report two cases of spontaneous rupture of renal angiomyolipoma (AML). In the first case, a 22-year-old woman was admitted with lower abdominal pain. She was diagnosed with rupture of left renal AML. Transcatheter arterial embolization (TAE) was performed for three times to preserve renal function, and the size of AML decreased to 6.5 cm from 10 cm. In the second case (74-year-old woman), the chief complaint was lower abdominal pain. The clinical diagnosis of this patient was rupture of right renal AML. The size of this AML markedly reduced due to TAE. TAE is an effective therapy for rupture of renal AML.     

Subarachnoid hemorrhage possibly caused by a saccular carotid artery aneurysm within the cavernous sinus. Case report

Aneurysms arising from the intracavernous portion of the internal carotid artery very rarely rupture. A patient is presented in whom rupture of an aneurysm wholly within the cavernous sinus caused a subarachnoid hemorrhage. The aneurysm was successfully clipped via a direct surgical approach. The possible mechanism by which subarachnoid hemorrhage occurred is briefly discussed.
