Recipient artery dissection during extracranial-intracranial bypass surgery: Two case reports

Figure 2 Intra- and postoperative image findings (case 1). A: Intima and media (yellow arrow) of recipient artery dissected from the adventitia layer (black arrow) after arteriotomy; B: To prevent dissection, we performed immediate suturing to ensure that the intima and adventitia were not separated; C: Dissecting aneurysm (yellow arrow) occurred at the anastomosis site after temporary clip removal at the recipient artery; D: Pseudoaneurysm gradually progressed; E: Before further dissection, the dissected portion was trapped using a clip; F: Postoperative brain computed tomography angiography confirmed arterial anastomosis between superficial temporal artery and distal middle cerebral artery.
