There are three main types of bypass surgery, including indirect, direct, and combined revascularization. Many studies have verified the effectiveness of extracranial-to-intracranial (EC-IC) bypass surgery to prevent cerebral ischemia in MMD 4, 5, 6. It can be treated by surgical revascularization 4. Ischemic events are the most common initial presentation while hemorrhagic strokes are more frequent in adults 3. The MMD prevalence peaks at two ages: around 10 years and at 30–45 years 2. Moyamoya disease (MMD) is a chronic and progressive steno-occlusive cerebrovascular disease 1. Incision infection, using a skin stapler, higher BMI, and cutting off large branch vessels in the flap are risk factors for PWH.

The area under the curve for risk factors for PWH on a receiver operating characteristic curve was 0.853. Multivariate logistic regression analysis suggested that incision infection ( P = 0.026, OR 12.958), using a skin stapler ( P = 0.030, OR 4.335), cutting off large branch vessels in the flap ( P = 0.009, OR 5.227), and BMI ( P = 0.027, OR 1.204) were risk factors. The standard chi-squared test showed significant differences in incision infection ( P = 0.010), suture mode ( P = 0.047), and cutting off large branch vessels in the flap ( P < 0.001). Student’s t test showed significant differences in BMI ( P = 0.040) and fever time ( P = 0.050). 5 patients (4.0%) had redness 2 patients (1.6%) had swelling 2 patients (1.6%) had fat necrosis 3 patients (2.4%) had incision infection and 3 patients (2.4%) had flap necrosis. 15 (12.0%) patients had incision complications. The mean age of these patients was 43.3 ± 10.0 years. The wounds were assessed and measured on the third and seventh days after surgery. A total of 125 patients with MMD were enrolled in this prospective observational study. We aimed to analyze risk factors for PWH in MMD with a complete Y-shaped incision. Moyamoya disease (MMD) is a chronic occlusive cerebrovascular disease that can be treated with revascularization. Surgery increases the risk of poor wound healing (PWH) due to the impact on the blood supply to the flap.
