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 was detected subarachnoid hemorrhage admitted to our center. During the first angiography, a pulsatile blister aneurysm was revealed and the aneurysm was also detected enlargement 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...

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...

Blood blister-like aneurysms (BBAs) are rare but very dangerous and challenging to treat. Recurrence and rebleeding are often reported, and many neurosurgeons and interventional radiologists are discouraged by such poor outcomes. Currently, there is no standard method to treat this type of aneurysm. We describe 5 cases of ruptured BBAs in the supraclinoid segment of the internal carotid artery, which were treated successfully using a suturing technique. No patient experienced recurrence or rebleeding, and all patients had a good prognosis...

BACKGROUND: Internal carotid artery (ICA) reconstruction is still the most effective treatment for a blood blister-like aneurysm (BBA) on the supraclinoid segment of the ICA, and clipping after wrapping has the most precise effects. However, the materials used are most often artificial. This study examined the use of autologous dura to replace the artificial materials used for wrapping after suturing a BBA. CASE DESCRIPTION: A 38-year-old man was hospitalized for subarachnoid hemorrhage (SAH)...

BACKGROUND: Blood blister-like aneurysms (BBAs) are a subgroup of aneurysms located on non-branching sites of the internal carotid artery (ICA) and characterized by small size, a fragile wall, and a poorly defined broad-based neck. Both direct surgery and endovascular treatment for BBA are often challenging. Some of them were reported to look like a true saccular aneurysm, and the misdiagnosis of BBA might result in catastrophic outcomes. The purpose of this study is to clarify the clinical and intraoperative findings of saccular BBAs...

REVIEW
Torstein R Meling
Treatment of blood blister-like aneurysms (BBAs) of the supraclinoidal internal carotid artery (ICA) is challenging and the optimal treatment is yet to be defined. The treatment options for ICA BBAS are microsurgery, endovascular therapy, or a combination of the two. The microsurgical armamentarium consists mainly of direct aneurysm clipping with or without protective EC-IC bypass, clip-wrapping, or trap ligation with ICA sacrifice with or without EC-IC bypass. The endovascular treatment options are mainly endovascular ICA ligation, multiple overlapping stents (≥ 3) with or without coiling, covered stents, or flow diverters...

Background Subarachnoid hemorrhage (SAH) secondary to rupture of a blister aneurysm (BA) results in high morbidity and mortality. Endovascular treatment with the pipeline embolization device (PED) has been described as a new treatment strategy for these lesions. We present the first reported case of PED retraction and foreshortening after treatment of a ruptured internal carotid artery (ICA) BA. Case description A middle-aged patient presented with SAH secondary to ICA BA rupture. The patient was treated with telescoping PED placement across the BA...

Two cases of ruptured blood blister-like internal carotid artery aneurysms for which low flow bypass was sufficient to attain successful treatment of trapping are reported. In the acute stage of rupture, it is troublesome to perform accurate examinations of tolerance to ischemia like balloon occlusion test(BOT)for estimating the required amount of bypass flow. In our cases, X-ray angiography perfusion(XAP)analysis was introduced, which could be performed in a couple dozen seconds without room-to-room transfer of patients, following the ordinary examination of diagnostic digital subtraction angiography...

Aberrant regeneration of the third nerve occurs as a result of synkinetic 'miswiring' of the third nerve following its injury, such as in third cranial nerve palsy due to tumor, trauma, or aneurysm. The case presented is an elderly woman with new vertical diplopia, which led to a diagnosis of a third cranial nerve palsy, thought to be caused by a 5 mm blister aneurysm of the posterior communicating artery. However, neuro-ophthalmological evaluation diagnosed aberrant regeneration of the third nerve, with the cause of her new vertical diplopia being an ipsilateral fourth nerve palsy...
