OBJECTIVE A direct comparison of endovascular versus microsurgical treatment of ruptured middle cerebral artery (MCA) aneurysms in randomized trials is lacking. As endovascular treatment strategies continue to evolve, the number of reports of endovascular treatment of these lesions is increasing. Herein, the authors report a detailed post hoc analysis of ruptured MCA aneurysms treated by microsurgical clipping from the Barrow Ruptured Aneurysm Trial (BRAT). METHODS The cases of patients enrolled in the BRAT who underwent microsurgical clipping for a ruptured MCA aneurysm were reviewed...

PURPOSE: Endovascular stents are widely used for the elective treatment of cerebral aneurysms. Acute stenting is performed in the management of dissections, pseudo-aneurysms, broad-based aneurysms or as a 'bail out' measure after coil migration. The purpose of this study is to review the safety of using stents in acute subarachnoid haemorrhage. METHODS: The stent registry of our institution was reviewed for procedures in patients with acute subarachnoid haemorrhage...

Blister-like aneurysms(BLA)are morphologically thin-walled fragile structures that are associated with a high risk of intraoperative rupture. BLAs presumably originate from an arterial dissection and often stem from a non-branching site on the supraclinoid segment of the internal carotid artery. We report a rare case of a patient who was successfully treated for a ruptured BLA originating from the anterior communicating artery(Acom). A 60-year-old woman presented with severe headache and loss of consciousness...

A 33-year-old man presented with aneurysmal subarachnoid hemorrhage from a ruptured, blister-type sidewall internal carotid artery (ICA) aneurysm. Balloon-assisted coiling was performed with residual neck. He subsequently developed severe vasospasm requiring intra-arterial therapies on multiple occasions, during which it was noted that despite widespread vasospasm, a focal segment of the ICA at the site of the aneurysm showed no significant spasm, suggesting underlying vessel abnormality. He was discharged without deficit and scheduled for flow diversion given concern over this potentially pathologic segment of vessel...

Blister aneurysms are rare lesions characterized by a bleb-like appearance in combination with prominent fragility. They mainly affect the supraclinoid internal carotid artery and they are often thought of as dissecting or even false lesions. Treatment of such lesions has been a matter of debate during the past few years with authors competing, in an ever changing field, for best results. Both surgical and endovascular modalities have been tried, with every technique having though its own limitations and pitfalls...

During implantation of an Ovation endograft for abdominal aortic aneurysm (AAA) correction, a patient experienced anaphylactic reaction after polymer leakage outside the device circuit. Procedure was completed after hemodynamic stabilization. Since postoperative day 2, patient complained of loss of legs strength. Medullar injury was excluded by electromyography test, and the clinical signs attributed to muscular necrosis and peripheral nerve involvement after arterial embolization. Furthermore, immediately after surgery, a wide erythematous area appeared in the lumbar region...

OBJECTIVE: Blister like aneurysm (BLA) is extremely challenging to treat; endoluminal reconstruction has emerged as the most promising treatment method. When to treat after the ictus, the timing of administration of antiplatelet and causal relationship between platelet function testing results and thrombo-embolism is unclear. We theorized that Prasugrel with a lower incidence of resistance may be a safe suitable alternative to clopidogrel in patients treated with a flow diverter (FD)...

BACKGROUND: Blood blister aneurysms (BBA) are a rare subset of intracranial aneurysms that represent a therapeutic challenge from both a surgical and endovascular perspective. OBJECTIVE: To report multicenter experience with flow diversion exclusively for BBA, located at non-branching segments along the anteromedial wall of the supraclinoidal internal carotid artery (ICA). METHODS: Consecutive cases of BBA located at non-branching segments along the anteromedial wall of the supraclinoidal ICA treated with flow diversion were included in the final analysis...

OBJECTIVE: Blood blister-like aneurysms (BBAs) in the dorsal segment of the internal carotid artery (ICA) are fragile and difficult to treat, and the optimal treatment for BBAs is still controversial. We report clinical and angiographic results with procedural details for the treatment of BBA by using the endovascular patch embolization method. METHODS: We retrospectively reviewed patients who presented with subarachnoid hemorrhage(SAH) caused by ICA-BBAs and were treated with the endovascular patch embolization method in our center from October 2011 to March 2015...

The use of Willis covered stent (WCS) for intracranial aneurysms has increased based on the promising results of previous studies about its safety and effectiveness. With the accumulation of cases, reports about peri-procedural complications are emerging. In our department, 25 patients were treated with WCS during December 2015 to March 2017. We here reported an unexpected technical complication occurred in the treatment with the WCS for a blood blister-like aneurysm (BBA). During the procedure, the distal end of the stents detached from the dilating balloon partially or as a whole...

BACKGROUND AND PURPOSE: Hemodynamics play a driving role in the life cycle of brain aneurysms from initiation through growth until eventual rupture. The specific factors behind aneurysm growth, especially in small aneurysms, are not well elucidated. The goal of this study was to differentiate focal versus general growth and to analyze the hemodynamic microenvironment at the sites of enlargement in small cerebral aneurysms. MATERIALS AND METHODS: Small aneurysms showing growth during follow-up were identified from our prospective aneurysm database...

Internal carotid artery (ICA) blister aneurysms are rare and challenging to successfully treat, using contemporary surgical or endovascular approaches, without partial or complete compromise of the parent vessel. We describe the use of a resheathable flow diverter, the Pipeline Flex Embolization Device (PFED) to perform stent-assisted coiling of a ruptured supraclinoid ICA blister aneurysm in a 56-year-old female who presented with a high-grade subarachnoid hemorrhage (SAH). The first PFED was deployed across the aneurysm neck to jail a microcatheter within the aneurysm dome, and then, two small coils were delivered into the aneurysm...

BACKGROUND: Supraclinoid blister aneurysms (BAs) of the internal carotid artery are uncommon and deadly, and appropriate treatment is controversial. Endovascular reconstruction may allow treatment through aneurysm isolation. We report a single-institution experience in the use of Enterprise stent-assisted coiling (ESAC) for treating BAs to appraise the safety and efficacy of this technique. METHODS: Patients treated with ESAC for a BA at our institution between 2013 and 2016 were retrospectively included in this study...

A male with detected subarachnoid hemorrhage was admitted to our center. During the first angiography, a pulsatile blister aneurysm was revealed and the aneurysm was also noticeably enlarged during the surveillance angiography. The patient accepted balloon-assisted clipping successfully. Blister aneurysms are at a high risk of rupture, high risk of regrowth, and need for multimodal management.

Objective: Blood blister-like aneurysm (BBA) is a kind of dorsal wall aneurysm and it is small, sessile, fragile and hazardous because of its high mortality and morbidity. Many challenges tried to establish the management or strategy. But so far, there is no optimal treatment of choice for the BBA. In this article, 17 cases of the ruptured BBA in one institute were analyzed retrospectively. The operative options were correlated with surgical and clinical outcomes. Materials and Methods: During 14 years between October, 2002 and October, 2016, 23 patients were treated for subarachnoid hemorrhage with ruptured dorsal wall aneurysms...

PURPOSE: Blood blister-like aneurysms (BBA) are small, friable, broad-based aneurysms that represent high risk for rerupture. Treatment of BBA is challenging, and may include surgical wrapping, clipping, multiple overlapping stents, and/or coiling. Flow diversion is a rapidly evolving treatment strategy for intracranial aneurysms, but the evidence for its use in cases of BBA is scarce. METHODS: A retrospective review of flow-diverter-treated, ruptured BBA cases at our tertiary care institution was undertaken...
