Internal maxillary artery to intracranial artery bypass: a case series of 31 patients with chronic internal carotid/middle cerebral arterial-sclerotic steno-occlusive disease

Abstract

By supplying an adequate flow to a larger flow territory of chronically stenotic/occlusive major cerebral arteries, IMA bypass surgery is efficient for restoring hemodynamics in selected patients and improving their neurological deficits.

Simultaneous PET-MRI imaging of cerebral blood flow and glucose metabolism in the symptomatic unilateral internal carotid artery/middle cerebral artery steno-occlusive disease

“…Nagasawa H et al found that there were significant decreases in cerebral glucose metabolic rate (CMRGlu) in areas in which no lesions had been detected based on using 18 F-FDG PET in MRI or CT scan in 7 patients with chronic ischemic cerebrovascular disease [20]. Yu Z et al previously reported seven patients who demonstrated improved glucose metabolism on 18 F-FDG PET after bypass surgery [28]. In the present study, we also focused on the changes that occurred in glucose metabolism between before and after bypass surgery in chronic ischaemic cerebrovascular disease.…”

“…Cha et al compared resting state cerebral perfusion evaluated using ASL and glucose metabolism evaluated using 18 F-FDG PET in 20 normal volunteers and found a good overall correlation between perfusion and glucose metabolism [42]. Yu Z et al found that bypass surgery changed CBF and FDG uptake of chronic ischaemic cerebrovascular disease [28]. However, they did not obtain these data simultaneously.…”

“…18 F-FDG PET imaging shows promise as an indicator of the effectiveness of therapies in cerebral ischaemia [19]. Yoshida, K. et al combined measurements of CBF and cerebral glucose metabolism to evaluate cognitive changes after carotid endarterectomy [27], and Yu Z et al used 18 F-FDG PET/CT to evaluated 7 patients who underwent STA-MCA bypass surgery [28]. However, few studies have focused on combining measurements of CBF and 18 F-FDG uptake, especially using an integrated simultaneous PET/MR scanner, to evaluate patients after STA-MCA bypass surgery.…”

Sequential approach of internal maxillary-to-middle cerebral artery bypass and endovascular occlusion for giant middle cerebral artery aneurysm: a case report

“…These benefits are highlighted in cadaveric and radiological studies aimed to define the IMaxA anatomy, illustrate a novel method for harvesting, and prepare it for extracranial-to-intracranial bypass [10][11][12][13]. Several recent articles discussed good outcomes of IMaxA to MCA bypass in patients with different complex aneurysms [14][15][16][17].…”

Experience of Extracranial-Intracranial Bypass With Using Maxillary Artery

“…В последнее время в научной литературе все чаще появляются данные об использовании ВЧА как альтернативной артерии-донора для реваскуляризации. Это связано с тем, что использование ВЧА в качестве донора имеет ряд преимуществ: по сравнению с низкопотоковым анастомозом -больший объемный кровоток (40,0-81,36 мл/мин) и более высокий показатель отдаленной проходимости [7,15,16], по сравнению с классическим высокопотоковым шунтомотсутствие необходимости осуществлять доступ на шее, более короткий шунт, отсутствие необходимости туннелирования мягких тканей, что снижает риски его несостоятельности [15,17].…”
