Blood-blister like aneurysms (BBAs) are challenging lesions because of their wide fragile neck. Flow-diverting stents (FDSs), such as the Pipeline Embolization Device (PED), have been applied to treat BBAs less amenable to more established techniques of treatment. However, the use of FDSs, including the PED, in acute subarachnoid hemorrhage (SAH) still remains controversial. We report a case of aneurysm regrowth following PED application for a ruptured BBA that overlapped the origin of the dominant posterior communicating artery (PCoA), which was successfully treated after coil trapping of the origin of the fetal-type PCoA...

OBJECTIVE The Barrow Ruptured Aneurysm Trial (BRAT) is a prospective, randomized trial in which treatment with clipping was compared to treatment with coil embolization. Patients were randomized to treatment on presentation with any nontraumatic subarachnoid hemorrhage (SAH). Because all other randomized trials comparing these 2 types of treatments have been limited to saccular aneurysms, the authors analyzed the current BRAT data for this subgroup of lesions. METHODS The primary BRAT analysis included all sources of SAH: nonaneurysmal lesions; saccular, blister, fusiform, and dissecting aneurysms; and SAHs from an aneurysm associated with either an arteriovenous malformation or a fistula...

OBJECTIVE Blood-blister aneurysms (BBAs) of the internal carotid artery (ICA) have a poor natural history associated with high morbidity and mortality. Currently, both surgical and endovascular techniques are employed to treat BBAs; thus, the authors sought to perform a meta-analysis to compare the efficacy and safety of these approaches. METHODS A literature search of PubMed, MEDLINE, and Google Scholar online databases was performed to include pertinent English-language studies from 2005 to 2015 that discussed the efficacy and safety of either surgical or endovascular therapies to treat BBAs...

Blister aneurysms at non-branching sites of the dorsal internal carotid artery (dICA) are fragile, rare, and often difficult to treat. The purpose of this study is to address the demographics, treatment modalities, and long-term outcome of patients treated for dICA blister aneurysms. A retrospective review of medical records identified all consecutive patients who presented with a blister aneurysm from 2002 to 2011 at our institution. Eighteen patients (M=7, F=11; mean age: 48.4±15.1years; range: 15-65years) harbored a total of 43 aneurysms, 25 of which were dorsal wall blister aneurysms of the ICA...

BACKGROUND AND IMPORTANCE: As the use of flow-diverting stents (FDSs) for intracranial aneurysms expands, a small number of case reports have described the successful treatment of blister aneurysms of the internal carotid artery with flow diversion. Blister aneurysms are uncommon and fragile lesions that historically have high rates of morbidity and mortality despite multiple treatment strategies. We report a case of rebleeding after treatment of a ruptured blister aneurysm with deployment of a single FDS...

OBJECTIVE: Intracranial blood blister-like aneurysm (BBA) is a rare type of aneurysm that lacks all layers of the arterial wall. These fragile aneurysms have the propensity to rupture with minimal manipulation, which makes them hazardous and difficult to treat. The present study evaluated the safety and feasibility of endovascular treatment of BBAs with the Willis covered stent. MATERIALS: Thirteen patients (7 men and 6 women, age range 28-68 years) who presented with ruptured BBAs and were treated with the Willis covered stent were retrospectively reviewed...

BACKGROUND: Although there have been many studies on primary hemorrhagic neurovascular diseases (PHNVDs) in different populations, a study focusing on PHNVDs in Tibetan people was still lacking. This study aimed to explore the notable characteristics of Tibetan PHNVDs by comparing the most three common PHNVDs (aneurysmal subarachnoid hemorrhage, spontaneous intracerebral hemorrhage and arteriovenous malformation) in our institution between Tibetan and Han patients. METHODS: In this retrospective observational study, the hospital information system (HIS) was utilized to access the records of patients with PHNVDs...

BACKGROUND: Blood blister aneurysms (BBAs) of the internal carotid artery (ICA) are very challenging vascular lesions for neurosurgeons as they are very fragile and difficult to clip. They are commonly found at the dorsal wall of the ICA. Trapping is an alternative for these lesions, accompanied by vascular reconstruction. However, they are sometimes close to the posterior communicating artery (PcoA) and anterior choroidal artery (AchoA). CASE DESCRIPTION: A 30-year-old man presented with subarachnoid hemorrhage due to rupture of a BBA in the right distal ICA...

Intracranial dissecting aneurysms (IDAs) are an important cause of subarachnoid hemorrhage, stroke, or compression of intracranial structures. Since the availability of endovascular treatment and the advantage of intraprocedural anticoagulation, an endovascular strategy has become the mainstay of their therapy. But in some cases selective aneurysm obliteration by the endovascular approach is impossible or associated with an unacceptable risk of morbidity. This is particularly true when the IDA is a blood blister-like aneurysm or when dissection affects peripheral branches of the internal carotid artery...
