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...

A middle-aged patient with an internal carotid-posterior communicating artery aneurysm and basilar artery tip aneurysm was treated by stent-assisted coiling. One ischemic infarction and two transient ischemic attacks occurred with the same symptoms (inability to walk unassisted and tendency to fall to the left) during the first 2 years post-treatment. The ischemic infarction was found in the right side of the pons, consistent with the vascular territory of the stent-containing vessel. The cause of the delayed ischemic stroke was investigated on DSA and cone beam CT, which revealed that the proximal end of the stent, one marker band, was just covering a small perforating artery of the basilar artery trunk...

Contrast-induced encephalopathy is a very rare complication associated with endovascular treatment of intracranial aneurysms. Patients with renal dysfunction may be prone to developing contrast medium neurotoxicity as a result of delayed elimination of the contrast medium in renal metabolism. This article focuses on our experience with contrast-induced encephalopathy in patients with end-stage renal disease requiring hemodialysis. The authors retrospectively reviewed five patients diagnosed with contrast-induced encephalopathy who underwent aneurysm coil embolization at their institution from January 2006 to December 2015...

A man aged 61 years with a history of a ruptured basilar fenestration aneurysm underwent unassisted coiling in 1997 and repeat intervention for a recurrence at the aneurysm mouth in 2011. At repeat intervention, the decision was made to intentionally leave some filling at the base to preserve the parent vessels. Stent-assisted coil embolization, although technically feasible, was not pursued given the relative risks of the procedure. In 2017, the patient returned for repeat surveillance and further coil compaction was found at the aneurysm base...

Endoscopic third ventriculostomy (ETV) is a common treatment for noncommunicating hydrocephalus. Although rare, vascular injury and traumatic pseudoaneurysm development during ETV have been reported. The authors present the case of a 13-year-old boy who underwent repeat ETV (rETV) for shunt and ETV failure, and who suffered an intraoperative subarachnoid hemorrhage due to iatrogenic injury to the basilar tip, with subsequent development of a pseudoaneurysm. Despite initial primary coil embolization, the aneurysm recurred and was definitively treated with flow diversion...

OBJECTIVE In various disease processes, including unclippable aneurysms, a bypass to the upper posterior circulation (UPC) including the superior cerebellar artery (SCA) and posterior cerebral artery (PCA) may be needed. Various revascularization options exist, but the role of intracranial (IC) donors has not been scrutinized. The objective of this study was to evaluate the anatomical feasibility of utilizing the anterior temporal artery (ATA) for revascularization of the UPC. METHODS ATA-SCA and ATA-PCA bypasses were performed on 14 cadaver specimens...

Background Aneurysms of the perforating arteries arising from the basilar artery trunk are rare and represent a therapeutic challenge. Methods A basilar perforator aneurysm was initially treated by the stent-in-stent technique. Enlargement of the aneurysm was seen on follow up and the sac was secondarily coiled using two extremely soft bare coils, delivered through a one-marker microcatheter. Results At 6 months, the patient had a modified Rankin Scale score of 0 and cerebral arteriography demonstrated complete occlusion of the lesion...

BACKGROUND: Dissecting aneurysms of the basilar artery (BA) are rare lesions, and the management of them has been controversial and challenging. The treatment becomes much more difficult when the patient has a disorder such as aortitis syndrome, which makes cerebral arteries occluded and tortuous. We describe a case of a ruptured BA dissecting aneurysm associated with aortitis syndrome, successfully treated with hybrid neurovascular surgery. CASE DESCRIPTION: A 64-year-old woman with a medical history of aortitis syndrome developed a severe headache and was diagnosed with a subarachnoid hemorrhage from a BA dissecting aneurysm...

Background Intracranial wide-neck aneurysms at the arterial bifurcations, especially in the aneurysms where the bifurcating branches emanate directly from the base of the aneurysm, have been particularly difficult on which to perform endovascular treatment. The 'Y'-configuration, double stent-assisted coil embolization is an option for the treatment of these difficult aneurysms, allowing the closure of the aneurysm, preserving the parent arteries. Material and methods In a nine-year period, 546 intracranial aneurysms in 493 patients were treated at our center by endovascular approach...

The objective of this paper was to report a rare complication of basilar artery (BA) tourniquet treatment of a giant basilar tip aneurysm, and to discuss possible causes for the formation of a de novo giant posterior cerebral artery (PCA) aneurysm. A 34-year-old woman underwent satisfactory treatment of a ruptured giant basilar bifurcation aneurysm by BA ligation (Drake tourniquet) in 1985. She presented 25 years later with a new aneurysm in the left PCA, successfully treated by coil embolization. To the authors' knowledge, this is the first case of de novo aneurysm formation on a PCA, and the first de novo aneurysm reported as a complication of BA ligation therapy by Drake tourniquet...

The horizontal stenting technique facilitates endovascular treatment of wide-necked bifurcation intracranial aneurysms. Previous literature shows, however, that subsequent coil embolization at initial treatment results in incomplete obliteration in many cases. The authors present two consecutive cases of wide-necked large bifurcation aneurysms to describe an additional coil embolization technique following horizontal stenting. The patients were a 53-year-old female with an unruptured internal carotid artery terminus aneurysm and a 57-year-old female with a recurrent basilar artery tip aneurysm...

OBJECTIVE: Stents are widely used in coil embolization of intracranial aneurysms, but on occasion, a microcatheter must traverse a stented segment of artery (so-called trans-cell technique) to select an aneurysm, or double stenting may necessary. In such situations, microguidewire passage and microcatheter delivery through a tortuous stented parent artery may pose a technical challenge. Described herein is a microguidewire looping technique to facilitate endovascular navigation in these circumstances...
