Distal middle cerebral artery (MCA) aneurysms often have non-saccular morphology and cannot be clipped, requiring revascularization and trapping instead. Combination bypasses are needed when 2 arteries exit the aneurysm, and extracranial-intracranial and intracranial-intracranial bypasses can be used. This video demonstrates a combination bypass used to treat a previously stented distal MCA aneurysm with both a superficial temporal artery (STA)-to-MCA bypass and an M2-to-M2 reanastomosis. This 56-yr-old man presented with distal left-sided MCA aneurysm 2 years earlier and attempted stent-assisted coiling was aborted after the aneurysm was perforated with stenting alone...

BACKGROUND: The hemodynamic changes that occur after high-flow (extracranial-intracranial) EC-IC bypass surgery with internal carotid artery (ICA) ligation are not well known. OBJECTIVE: To assess blood flow changes after high-flow EC-IC bypass with ICA ligation by time-resolved 3-dimensional phase-contrast (4D Flow) magnetic resonance imaging (MRI). METHODS: We enrolled 11 patients who underwent high-flow EC-IC bypass. 4D Flow MRI was performed before and after surgery to quantify the blood flow volume (BFV) of the ipsilateral ICA (BFViICA), bypass artery (BFVbypass), contralateral ICA (BFVcICA), and basilar artery (BFVBA)...

BACKGROUND: Near-infrared spectroscopy (NIRS) is used worldwide to monitor regional cerebral oxygenation (rScO2) during cardiopulmonary bypass (CPB). Intervention protocols meant to mitigate cerebral desaturation advocate to increase mean arterial pressure (MAP) when cerebral desaturation occurs. However, the isolated effect of MAP on rScO2 is uncertain. The aim of the present study was in a randomized, blinded design to elucidate the effect of 2 distinct levels of MAP on rScO2 values during CPB...

OBJECTIVE Cerebrovascular bypass surgery is a challenging yet important neurosurgical procedure that is performed to restore circulation in the treatment of carotid occlusive diseases, giant/complex aneurysms, and skull base tumors. It requires advanced microsurgical skills and dedicated training in microsurgical techniques. Most available training tools, however, either lack the realism of the actual bypass surgery (e.g., artificial vessel, chicken wing models) or require special facilities and regulations (e...

Extracranial-to-intracranial (EC-IC) bypass surgery may be necessary in patients with moyamoya disease and other ischemic conditions. However, there is a potential risk of wound-related complications in some cases. In this study, we report our approach to prevention of wound-related complications in EC-IC bypass, and technical consideration and pitfalls of surgery are discussed. This study included 89 patients with ischemic-onset moyamoya disease and atherosclerotic disease, who underwent 108 superficial temporal artery (STA)-to-middle cerebral artery bypass procedures...

In this 3-dimensional video, we perform a side-to-side and end-to-side double anastomosis using the parietal-branch of the superficial temporal artery (STA) to provide flow augmentation in a symptomatic 59-yr-old male with bilateral internal carotid artery occlusion at the origin, and left M1 segment occlusion. The patient suffered multiple left hemispheric strokes despite maximal medical therapy and was found to have poor hemodynamic reserve in the left hemisphere during evaluation with regional and global blood oxygenation level-dependent functional magnetic resonance imaging with CO2-challenge as well as quantitative magnetic resonance angiography and noninvasive optimal vessel analysis pre- and post-acetazolamide challenge...

BACKGROUND: Intra-operative blood flow assessments during cerebral bypass would ideally assess vessel patency, downstream perfusion, and risk of post-operative hyperperfusion syndrome (HPS). Previous studies using Indocyanine Green-based flow analyses (ICG-BFA) have identified multiple parameters that can intra-operatively track bypass-related changes in cerebral perfusion and potentially predict post-operative HPS risk. Herein, we determine the most robust parameter and anatomic location for intra-operative ICG-BFA assessment of bypass-related perfusion changes and prediction of post-operative HPS risk...

RATIONALE: Extracranial-intracranial saphenous vein bypass (EC-IC SVB) remains indispensable for treating giant cavernous aneurysms. We report an unusual case of a giant cavernous aneurysm in an elderly patient treated with EC-IC SVB in a hybrid operating room. Immediately following proximal ligation of the internal carotid artery (ICA), she suffered an acute intraoperative encephalocele. PATIENT CONCERNS: A 71-year-old woman had suffered from severe headache and double vision for 4 months...

Fibromuscular dyplasia (FMD) is an under-recognized non-atherosclerotic, non-inflammatory arteriopathy that occurs most commonly in middle-aged women, but may affect individuals of all age groups. FMD may result in stenosis, aneurysm, dissection, occlusion, or arterial tortuosity. Recently published data demonstrated a genetic association of FMD with a variant in the phosphatase and actin regulator 1 gene (PHACTR1), substantiating that the pathogenesis of this condition has genetic contribution. The renal and extracranial carotid and vertebral arteries are most often involved, although any arterial bed may be affected...

Intracranial cerebral atherosclerosis is a significant predictor of stroke after coronary artery bypass grafting (CABG). However, there is limited information on intracranial occlusive lesions in patients undergoing CABG. The purpose of the study was to elucidate the precise prevalence and distribution of occlusive lesions of the extracranial and intracranial arteries in patients undergoing CABG. Between 2009 and 2016, 205 patients underwent preoperative magnetic resonance angiography and elective CABG. The prevalence and the distribution of occlusive lesions were retrospectively examined by preoperative magnetic resonance angiography...

BACKGROUND: Although most intracranial aneurysms can be treated with microsurgery or endovascular procedure alone, a subset of aneurysms may require a combined approach. The purpose of this study was to assess the efficacy of endovascular interventions combined with bypass surgery for the treatment of complex intracranial aneurysms. METHODS: We retrospectively reviewed medical records from a prospectively maintained patient database to identify patients who underwent endovascular treatment of an intracranial aneurysm at our institutes between 2007 and 2017...

Surgical revascularization continues to play an important role in the management of complex intracranial aneurysms and ischemic cerebrovascular disease. Graft spasm is a common complication of bypass procedures and can result in ischemia or graft thrombosis. The authors here report on the first clinical use of botulinum toxin to prevent graft spasm following extracranial-intracranial (EC-IC) bypass. This technique was used in 3 EC-IC bypass surgeries, 2 for symptomatic carotid artery occlusions and 1 for a ruptured basilar tip aneurysm...

In 1967, the first extracranial to intracranial (EC-IC) arterial anastomosis was performed. Since that time, EC-IC bypass surgery has become a widely accepted surgical treatment for patients with IC stenotic or occlusive atherosclerotic lesions. This article will discuss the history, indications, types, surgical methods, and complications of the EC-IC bypass.

Extracranial carotid artery aneurysms (ECAA) are less commonly seen disease. It is still difficult to determine the optimal treatment strategy because of limitations in reporting of results and confounding by indications based on the available literature. We depict a hybrid operation combining surgery with balloon occlusion to achieve distal outlet control, aneurysm resection, and reconstruction of parent internal carotid artery for the treatment of extracranial carotid artery aneurysms with good outcomes according to a 2-year follow up...

In neurosurgery, extracranial-to-intracranial (EC-IC) bypass surgery is necessary for patients who have undergone surgery in which the superficial temporal artery (STA) was already used for a different bypass procedure or was damaged. Here we report our experience with EC-IC bypass using the occipital artery (OA) in patients in whom the STA was unavailable, and discuss the technical considerations and pitfalls. Five patients with ischemic-onset moyamoya disease and atherosclerotic disease were included. Two patterns of skin incisions were planned according to the OA pathway and recipient artery location...

OBJECTIVE: Skull base meningiomas carry a nonnegligible risk of recurrence. In particular, those arising from the sphenoid wings or middle cranial fossa penetrate into extracranial regions, uncommonly showing massive expansion into the craniofacial regions on recurrence. The role of endoscopic endonasal surgery for those intractable lesions remains unclear. METHODS: We performed endoscopic endonasal craniofacial surgery for 8 recurrent meningiomas invading into the pterygopalatine fossa, infratemporal fossa, nasopharynx, paranasal sinus, or orbit, comprising 2 meningothelial and 1 fibrous meningiomas (World Health Organization [WHO] grade I), 3 atypical and 1 clear cell meningiomas (grade II), and 1 anaplastic meningioma (grade III)...
