Bypass Surgery

Coronary artery bypass graft (CABG) surgery performed via sternotomy (incision of the breastbone) can cause severe pain after surgery; this can slow recovery and increase the need for opioid pain relievers. This study investigates whether placing a catheter to deliver a local anesthetic to the superficial parasternal intercostal plane reduces pain following this type of heart surgery. Patients undergoing CABG via sternotomy will be randomly assigned to either the catheter-based analgesia group or the standard pain management group. The researchers will compare postoperative pain levels and analgesic medication requirements between the two groups to determine whether this technique improves postoperative pain control.

This study will evaluate the application of a metaverse-based surgical simulation platform in extracranial-intracranial (EC-IC) bypass surgery. The study population will include patients with moyamoya disease or chronic cerebral ischemia who are scheduled to undergo EC-IC bypass surgery. Before surgery, preoperative brain computed tomography images will be imported into the metaverse surgical simulation platform. During surgery, extended reality technology will be used to provide precise localization of the relevant vessels, including both the donor and recipient arteries. The primary objective is to assess the localization accuracy of this platform. The study will also investigate whether this technology can facilitate a minimally invasive surgical approach and improve surgical safety.
