Regression analysis of bleeding factors and the correlation between FPE and NLR after mechanical thrombectomy for acute anterior circulation large vessel occlusion.

Acute anterior circulation large vessel occlusion refers to a blockage in the blood flow of one of the major blood vessels in the anterior (front) part of the brain. Acute anterior circulation large vessel occlusion can lead to a range of symptoms, including sudden headache, difficulty speaking or understanding speech, weakness or numbness on one side of the body and loss of vision in one eye. According to relevant data, mechanical thrombectomy in the treatment of the large vessel recanalization rate can reach 70%. However, hemorrhage is one of the serious complications after mechanical thrombectomy, and it is the main factor leading to the deterioration of neurological function and death of patients after large blood vessels. Therefore, the risk factors of bleeding in patients were analyzed before surgery, and effective prevention during and after surgery had positive significance for patients undergoing mechanical thrombectomy. This study uses regression analysis to analyze the correlation between bleeding factors and FPE and NLR after mechanical thrombectomy for acute anterior circulation large vessel occlusion. We retrospectively analyzed 81 patients with acute anterior circulation large vessel occlusion who underwent mechanical embolization in our hospital from September 2019 to January 2022 and separated them into a bleeding group (46 patients) and a non-bleeding group (35 patients) based on the presence or absence of bleeding after surgery.
