We have Dr. Shi, who's going to be speaking on bypass surgery for the treatment of complex aneurysms in 71 patients. And we have the next speaker on deck, please. Good afternoon, everyone. I'd like to talk about bypass surgery for treatment of complex aneurysm in 71 cases. First of all, I'd like to review the maxillary artery anatomy of the pterygoid part. Match the MCA in diameters. We show the distance from the maxillary artery to the MCA. In this series, we treat aneurysm without perforators in 43 cases after bypass. Here is the cavernous sinus aneurysm. Difficult to direct the clipping and the coil treatment. We're tripping the aneurysm of the maxillary artery bypass. Here is the infotemporal fossa and the opening of the salivary fuselage through the tyrenoid operates, which cut off the zygomatic arch. We performed an end-to-end anastomosis of the maxillary artery to the radial artery graphite. After that, we performed an end-to-end anastomosis of the radial artery graphite to the intracranial ICA, followed by the tripping the aneurysm through the ligature of the cervical internal carotid artery prosigma to the aneurysm, and clipping the intracranial ICA prosigma to the aneurysm. Postoperative aneurysm showing tripping the aneurysm disappears, and the patterns of the radial artery graphite from maxillary artery to the ICA, the cerebral artery, feeling the full, the patterns recover to normal life. Reversal flow bypass surgery for treatment aneurysm with the perforators in the 28 cases. Here is the surpounding aneurysm of the M1 segment. I think there is no way for tripping and coil treatment because the aneurysm from the perforators to syphilis. Reversal flow bypass surgery for treatment of this perforator's aneurysm. Here is the infratemporal fossa and the opening of the salivary fuses through the tyrenol operates. Here is the end-to-end anastomosis of the maxillary artery to the radial artery graphite. After that, we perform the end-to-side anastomosis of the radial artery graphite to the M2 segment distal to aneurysm, followed by clipping the M1 segment prosigma to the aneurysm, creating reversal flow to the aneurysm in the body from maxillary artery. Postoperative aneurysm showing, the aneurysm became the small residual maxillary. The patents of maxillary artery patented the cerebral artery. Feeling for here is the dolical atactic aneurysm. We performed bypass surgery. Post more than seven years follow-up aneurysm, CT aneurysm showing dolical atactic aneurysm disappears. The patents recover to normal life. Summary is maxillary artery with the radial artery graphite is an effective minimally invasive treatment modality for slight patents with complex aneurysm. Thank you for listening. Thank you very much.
