The premammillary artery (PMA) is a branch of the posterior communicating artery (PCoA). While the PMA is known to originate from the PCoA as demonstrated by most anatomical studies, it originates directly from the internal carotid artery in approximately 1% of patients. Cerebral aneurysms associated with the PMA have rarely been reported. We report an extremely rare case of a ruptured PMA aneurysm that was managed using endovascular treatment.

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...

Arteriovenious malformations (AVMs) are associated with significant morbidity and mortality, and have a rupture risk of ~3% per year. Treatment of AVMs must be tailored specifically to the lesion, with surgical resection being the gold standard for small, accessible lesions. Pre-operative embolization of AVMs can reduce nidal blood flow and remove high-risk AVM features such as intranidal or venous aneurysms, thereby simplifying a challenging neurosurgical procedure. Herein, we describe our approach for the staged endovascular embolization and open resection of AVMs, and highlight the advantages of having a comprehensively trained neurovascular surgeon leading a multi-disciplinary clinical team...

Objective: Aneurysm clipping and simultaneous hematoma evacuation through open craniotomy is traditionally recommended for ruptured cerebral aneurysms accompanied by intracerebral or intrasylvian hemorrhages. We report our experience of adapting a less invasive treatment strategy in poor-grade patients with intracerebral or intrasylvian hemorrhages associated with ruptured cerebral aneurysms, where the associated ruptured cerebral aneurysms were managed by endovascular coil embolization, followed by stereotactic aspiration of hematomas (SRH) using urokinase...

During aneurysm clipping, ischemic complications may occur and require a rescue treatment, usually surgical. We present two such cases that required urgent rescue treatment, performed through an endovascular route. Our first case presented with a non-ruptured right posterior inferior cerebellar artery (PICA) aneurysm. After permanent clip positioning, occlusion of the PICA occurred. An unsuccessful attempt of clip repositioning was performed. We therefore positioned a stent obtaining complete flow restoration...

Background In cases of subarachnoid hemorrhage due to aneurysm rupture, the administration of an anticoagulant or antiplatelet agent involves the risk of rebleeding from the aneurysm. There is a possibility of inducing thromboembolic events during the endovascular embolization of ruptured cerebral aneurysms. Patients and methods From April 2006 to March 2017, we treated a total of 70 patients with ruptured cerebral aneurysms with an endovascular technique. Among them, five patients (7.1%) showed intra-arterial thrombus formation...

Introduction: Balloon angioplasty can be a requisite approach for the treatment of symptomatic and/or severe vasospasm. Dual-lumen microcatheter balloons have multiple potential advantages for this indication including accommodating a 0.014-inch wire and the potential to deliver superselective vasodilators directly via the microcatheter prior to angioplasty. Methods: The authors reviewed a 3-year institutional experience with the Scepter XC balloon (Microvention, Tustin, CA, USA) in the treatment of postaneurysmal subarachnoid hemorrhage vasospasm, focusing on treatment methods, angiographic, and clinical results...

Aneurysms of blood vessels at the base of the brain are pathological focal out-pouchings, usually found at the branching points of the arteries. Aneurysm can remain silent for life. Clinical presentation is due to rupture and bleeding. In only 1.3% of cases it results in subdural hematoma, which is associated with direct interaction of the aneurysm with the basal arachnoid membrane. Multiple aneurysms are present in 15% to 33% of cases with subarachnoid hemorrhage. Assessment of these patients is more complicated, as there are no specific signs to pinpoint/detect the aneurysm that has ruptured...

OBJECTIVE: Endovascular aneurysm repair (EVAR) with the chimney technique (ch-EVAR) has been used for the treatment of aortic aneurysms as an alternative approach to fenestrated endografting or open repair. Nonetheless, the need for an upper extremity arterial access may contribute to a higher risk for periprocedural cerebrovascular events. This study reports on the perioperative cerebral and major adverse cardiac and cerebrovascular events (MACCE) after ch-EVAR. METHODS: The PERICLES registry (PERformance of the chImney technique for the treatment of Complex aortic pathoLogiES) is an international, retrospective multicenter study evaluating the performance of ch-EVAR for the treatment of complex aortic pathologies...

As a special subgroup of multiple intracranial aneurysms, mirror aneurysms are located bilaterally on the corresponding intracranial arteries. The current study sought to compare the clinical and demographic features of patients harboring mirror aneurysm, and to elucidate the corresponding risk factors. We performed a retrospective cohort study of 2641 intracranial aneurysms patients, who were admitted to our hospitals between January 2005 and June 2014. Patients were subdivided into three groups based on the inclusion criteria: (i) single (n=2250); (ii) non-mirror multiple (n=285); and (iii) mirror aneurysms (n=106)...

While cocaine use is thought to be associated with aneurysmal rupture, it is not known whether heroin use increases the risk of rupture in patients with non-mycotic saccular aneurysms. Our goal was to investigate the association between heroin and cocaine use and the rupture of saccular non-mycotic aneurysms. The medical records of 4701 patients with 6411 intracranial aneurysms, including 1201 prospective patients, diagnosed at the Brigham and Women's Hospital and Massachusetts General Hospital between 1990 and 2016 were reviewed and analyzed...

BACKGROUND: Stent placement can change the hemodynamics in basilar artery aneurysms. However, the effects of the stent placement can depend on the angle of vessel bifurcation. OBJECTIVE: The hemodynamics in and near the aneurysm are investigated for two angles of vessel bifurcation and two stent models. Some statistical indexes are calculated to evaluate the effects of the stent placements on the possibility of aneurysm rupture. METHODS: Computational fluid dynamics simulations and phantom model experiments are performed...

We describe an autopsy case of nontraumatic convexal subarachnoid hemorrhage (cSAH) accompanied by sylvian hematoma. A woman in her 50s was found dead in her house. On autopsy, massive cSAH accompanied by sylvian hematoma was observed. Because of the absence of subarachnoid hemorrhage (SAH) in the basal cistern, initial suspicion was that of a traumatic SAH. After a detailed investigation, a ruptured cerebral aneurysm of the distal middle cerebral artery was found in the hematoma, and the cSAH in this case was confirmed to be endogenous...

OBJECTIVE Although cigarette smoking is one of the strongest risk factors for cerebral aneurysm development and rupture, there are limited data evaluating the impact of smoking on outcomes after aneurysmal subarachnoid hemorrhage (SAH). Additionally, two recent studies suggested that nicotine replacement therapy was associated with improved neurological outcomes among smokers who had sustained an SAH compared with smokers who did not receive nicotine. METHODS Patients who underwent endovascular or microsurgical repair of a ruptured cerebral aneurysm were extracted from the Nationwide Inpatient Sample (NIS, 2009-2011) and stratified by cigarette smoking...

Cerebellar hemangioblastomas are rare tumors of the neuraxis. Only seven cases of hemangioblastoma associated with a cerebral aneurysm have been reported. We report a case of a patient who presented with acute onset headache as a result of subarachnoid hemorrhage (SAH) and hydrocephalus. Radiographic workup revealed a hemangioblastoma with an intratumoral aneurysm. Preoperative cerebral angiography was performed for both embolization as well as characterization of the aneurysm. The patient underwent a suboccipital craniotomy for tumor resection...
