Abstract

Background: Minimally invasive techniques for graft procurement are the norm in cardiac surgery and yet their use in neurosurgery is only in its infancy. We present the case of a 10-year-old boy presenting with fluctuating right facial and upper extremity weakness who was found to have a giant, partially thrombosed, fusiform aneurysm of the M1 segment of the left MCA. Methods: Endoscopic harvesting of the saphenous vein was performed with a procedure time of 30 minutes. The graft was used as an interposition graft between the common carotid artery and the superior M2 division of the MCA, which was tunneled subcutaneously. Once Doppler ultrasound confirmed good flow through the graft, an aneurysm clip was then secured on the M1, proximal to the saccular component of the fusiform aneurysm and just distal to the anterior temporal branch. Results: Intraoperative 2D and 3D angiogram confirmed a patent extracranial to intracranial bypass with thrombosis of the giant fusiform M1 aneurysm. By 1-month post-operatively, he had returned to school and routine activities. He continues to do well 6 months post-operatively with a minimal and well-healed donor site scar. Conclusions: Endoscopic graft harvesting is an emerging option in the pediatric population undergoing extracranial to intracranial bypass, associated with lower wound complications and improved cosmesis.
