Professor Chen Wendou - Application of cerebral oxygen saturation monitoring in left middle cerebral artery M1 segment thrombectomy+cerebral aneurysm embolization

Clinical Application Case of Professor Chen Wendou's Team in Neurosurgery at Qianhai Life Insurance Guangxi Hospital

Recently, Professor Chen Wendou from the Neurosurgery Department of Qianhai Life Insurance Guangxi Hospital led a team to develop a comprehensive surgical plan for a 67 year old patient with cerebral infarction. Based on the patient's age and condition, it was decided to use cerebral oxygen saturation monitoring technology during the surgery. Under the supervision of the Bolian Zhongke MOC-200 Brain Tissue Oxygenation Monitor, the patient underwent a "left middle cerebral artery M1 segment thrombectomy" procedure. The monitoring results of cerebral oxygen saturation during the operation showed a decrease in left cerebral oxygen saturation, which was consistent with the imaging results. After surgery, the patient safely returned to the ward and was discharged smoothly after careful care by Professor Chen Wendou's medical team. Our products have received high praise from experts in different clinical fields for their ability to monitor brain tissue oxygen saturation during surgery.

Case Presentation

(After intubation under general anesthesia)

The surgery proceeded as scheduled. After anesthesia and intubation, the cerebral oxygen saturation showed a left side of 57% and a right side of 70%, with a difference of 13%. Intraoperative angiography of the aortic arch, bilateral common carotid arteries, and internal carotid artery. Imaging findings: Type I arch, distant from the distal end of the M1 segment of the left middle cerebral artery, no imaging is observed, suggesting an embolism and infarction of the M1 segment of the left middle cerebral artery. The monitoring results of cerebral oxygen saturation indicate a decrease in left cerebral oxygen saturation, which is consistent with the intraoperative imaging results.

(Imaging prompt: M1 segment of middle cerebral artery embolism and infarction, consistent with the monitor results)

After performing embolization and thrombectomy of the M1 segment of the left middle cerebral artery, it was found that the distal end of the left middle cerebral artery was reopened but severely narrowed and occluded. An aneurysm was observed at the bifurcation, with significant ejection from the aneurysm and visualization of the distal blood vessels. Considering that the narrowed area may be re occluded at any time, and there is a higher risk of aneurysm rupture and bleeding after opening the occluded area, aneurysm embolization and stent placement in the narrowed area for angioplasty are performed during surgery. After embolization of the aneurysm during surgery, the left cerebral oxygen suddenly decreased to 48%. After reconstruction, it was found that the distal blood vessel was not visible.

(Imaging prompt: No visualization of distal blood vessels)

The brain tissue oxygen saturation monitor combined with intraoperative angiography suggests cerebral vascular stenosis, which may indicate local cerebral tissue ischemia and hypoxia. Professor Chen Wendou's team immediately decided to use a stent to cover the narrowed area of the blood vessel. After re examination of the angiography, it was found that the narrowed area had improved compared to before. The aneurysm was slightly visualized without any signs of ejection, and the remaining blood vessels were well visualized. After anticoagulation with tirofiban, the patient's cerebral oxygen was restored to its preoperative state.

The surgical process went smoothly, and symptomatic treatments such as dilation, anti vascular spasm, and antiplatelet aggregation were given after surgery. The left brain oxygen value further increased, reaching consistency between the left and right brains. The patient safely returned to the ward and was discharged smoothly after careful care by the medical team.

In summary, the Bolian Zhongke MOC-200 Brain Tissue Oxygen Saturation Detector uses non-invasive, real-time continuous monitoring of brain oxygen saturation to promptly detect issues such as cerebral hypoxia, helping medical personnel to intervene early and optimize treatment plans. Its high sensitivity and specificity ensure the accuracy of monitoring data, reduce intraoperative and postoperative complications, and improve patient safety. Widely used in cardiac surgery, neurosurgery, intensive care, and other scenarios, the Bolian Zhongke MOC series brain tissue oxygen saturation not only ensures the life and health of patients, but also improves the safety quality and medical level of hospitals.
