“…In contrast to revascularization for aneurysm surgeries, bypass in the setting of tumour surgeries is far less common; the literature consists of only a few case reports and case series. With only a handful of studies older than 1990 [33-35], 1 to 2 reports/series on the topic have been released annually since then, without any observable geographic predominance. With a few exceptions, most of these publications report on direct bypasses in the anterior circulation.…”

Trends in Literature on Cerebral Bypass Surgery: A Systematic Review

et al. 2021

Introduction: Ever since the beginning of cerebral bypass surgery, the role of the bypass has been debated and indications have changed over the last 5 decades. This systematic literature research analysed all clinical studies on cerebral bypass that have been published from January 1959 to January 2020 for their year of publication, country of origin, citation index, role of and indication for bypass, bypass technique, revascularized territory, flow capacity, and title (for word cloud analysis per decade). Methods: A systematic literature research was conducted using PubMed, Web of Science, EMBASE, and SCOPUS databases. All studies that have been published until January 1, 2020, were included. Results: Of 6,013 identified studies, 2,585 were included in the analysis. Of these, n = 1,734 (67%) studies addressed flow-augmentation bypass and n = 701 (27%) addressed flow-preservation bypass. The most common indication reported for flow augmentation is moyamoya (n = 877, 51%), followed by atherosclerotic steno-occlusive disease (n = 753, 43%). For flow preservation, the most common indication is studies reporting on cerebral aneurysm surgery (n = 659, 94%). The increasing popularity of reporting on these bypass operations almost came to an end with the FDA approval of flow diverters for aneurysm treatment in 2011. Japan is the country with the most bypass studies (cumulatively published 933 articles), followed by the USA (630 articles) and China (232 articles). Discussion/Conclusion: Clinical studies on cerebral bypass surgery have become increasingly popular in the past decades. Since the introduction of moyamoya as a distinct pathologic entity, Asian countries in particular have a very active community regarding this disease, with an increasing number of articles published every year. Studies on bypass for chronic steno-occlusive disease peaked in the 1980s but have remained the main focus of bypass research, particularly in many European departments. The number of reports published on these bypass operations significantly decreased after the FDA approval of flow diverters for aneurysm treatment in 2011.

“…Extracranial–intracranial bypass, especially STA-MCA bypass, is regarded as an effective cerebral revascularization. [ 3 , 4 ] However, in 2011, previous studies concerning EC-IC bypass, especially the randomized trial of the carotid occlusion, [ 6 ] shown us negative effect. Even hemorrhage caused by reperfusion following the revascularization was not ignored.…”

“…Even some researches only achieved partial resection because of the severe bleeding. [ 3 ] In addition, before intracranial revascularization concerning skull base tumors, the balloon test occlusion (BTO) should be performed. However, compared with vascular lesions, the BTO concerning skull base tumors can obtain lower reliability, and the EC-IC bypass should be done for preventing ischemic event in the process of safe removal of skull base tumors.…”

“…Extracranial–intracranial bypass has been commonly utilized in the process of treating Moyamoya disease, giant fusiform aneurysms and other ischemic cerebrovascular diseases. [ 1 – 3 ] However, it is rarely studied that which method can be used to deal with sphenoid ridge meningioma associated with severe stenosis of the intracranial segments of the internal carotid artery (ICA). Tumor resection and prevention of ischemic stroke owing to severe stenosis of the ICA invaded by tumor should be taken into consideration simultaneously.…”

Rationale:Tumor resection and extracranial-intracranial bypass concerning medial sphenoid ridge meningioma associated with severe stenosis of the internal carotid artery (ICA) of intracranial segments has been rarely presented. Effective treatment as to the complex lesions may be complicated. Tumor resection and cerebrovascular protection should be both taken into consideration.Patient concerns:We presented one case of medial sphenoid ridge meningioma associated with severe stenosis of the internal carotid artery of intracranial segments. The patient suffered hyperthyroidism, mirror-image dextrocardia and congenital heart disease atrial septal defect simultaneously.Diagnoses:Before the neurosurgical treatment , the colleagues of department of cardiac surgery, anesthesiology and respiratory medicine agreed on our plan of resecting the tumor following the comprehensive evaluation of basal clinical conditions in the patient. For reducing the bleeding intraoperatively, the interventional branch performed digital subtraction angiography(DSA) and found collateral anastomosis between the supplying vessels of left middle meningeal arteries and anterior choroid arteries. No preoperative interventional embolization was determined considering the risk of cerebral ischemia.Interventions:The following subtotal resection of medial sphenoid ridge meningioma and left extracranial-intracranial bypass were carried out. Additionally, ipsilateral decompressive craniectomy was done. Post-operative imaging Computed tomography (CT), Computed tomography angiography (CTA) and Transcranial Doppler (TCD) indicated subtotal resection of tumor and bypass patency.Outcomes:The patient was discharged with the right limbs of muscle strength of grade IV. The muscle strength of the patient returned to grade V after 6 months of follow-up.Lessons:Comprehensive treatment of tumor resection and extracranial-intracranial bypass concerning medial sphenoid ridge meningioma associated with severe stenosis of the internal carotid artery of intracranial segments is effective.
