Delayed reopening of a superficial temporal artery to middle cerebral artery bypass graft occluded by a white thrombus during surgery

Abstract: Background: To the authors’ knowledge, reopening of a superficial temporal artery to middle cerebral artery (STA-MCA) bypass graft occluded by a white thrombus during the procedure and was observed several months after the surgery is relatively rare. Case Description: The authors encountered a case of moyamoya disease in an Asian female in her third decade of life, in whom a bypass recipient vessel was occluded by a white thrombus during surgery and remained occluded on magnetic resonance angiography (MRA)… Show more

“…As discussed in a previous study, some reports of the appearance of white thrombi during surgery for STA-MCA bypass have already been reported. [14,22,33] When analyzed for the appearance of white thrombi during the operation, Mikami et al [22] stated that higher MRA scores were significantly associated with thrombogenesis. [18] As part of a discussion based on this finding, it is a remarkable anatomical structure indicating that the recipient artery on the brain surface is fragile and thin in patients with advanced MMD presenting with higher MRA scores.…”

“…Some investigations reporting that the occluded bypass was recanalized in all cases prompted us to investigate this issue. [ 17 , 33 ] Regarding bypass occlusion using a vein graft in EC to IC bypass, a report from an Australian group is a powerful reference. [ 30 ] The authors proved that the flow rate specified for mean arterial pressure should not fall below a minimum of 40 ml/min to maintain blood flow for bypass based on the study by Sundt and Sundt.…”
