The carotid web is a double-layered membranous structure protruding into the lumen,primarily affecting the carotid bifurcation and bulb.It is considered as a potential risk factors for ischemic stroke.Carotid web can alter the structure of the carotid artery lumen,leading to hemodynamic abnormalities that increase the risk of thrombus formation.Once detached,it can cause intracranial arterial embolism,making it a common cause of stroke in young adults.This case report presents a case of restenosis after mechanical thrombectomy and carotid endarterectomy for carotid web-induced ectopic embolism.It provides references and insights for clinicians to recognize,diagnose and treat this disease.

Objective:To evaluate the safety and efficacy of digital technology-assisted debridement and bone and soft tissue reconstruction in the treatment of chronic osteomyelitis of the tibia.Methods:This retrospective study analyzed clinical data from 38 patients (26 males, 12 females; mean age 45.61±18.36 years, range 16-83 years) with chronic post-traumatic osteomyelitis complicated by soft tissue defects in the tibia, treated at the Department of Orthopaedics, Fourth Medical Center of PLA General Hospital between June 2021 and June 2023. There were 18 cases of traffic accidents, 6 cases of high-altitude falls, 6 cases of heavy objects and 6 cases of low-energy falls. Lesion sites: 12 cases in the upper segment of the tibia, 12 cases in the middle segment, and 14 cases in the lower segment. According to the Cierny-Mader classification, there were 24 cases of type III and 14 cases of type IV. Before the operation, the "3D point cloud technology" was used to plan the debridement range of bone and soft tissue. During the operation, the optical navigation system was used to monitor the debridement range in real time. The flap was designed by combining "Reading Tablet Treasure" with CT angiography, and the amount of bone graft was predicted by AI algorithm. The surgical method adopted is the Masquelet technique, namely thorough debridement, bone cement occupation and soft tissue repair in the first stage, and bone reconstruction in the second stage. Comparing the calculated bone defect amount and soft tissue defect area before the operation with the actual measured values after debridement. The cure rate of infection was evaluated by using the McKee bone infection treatment criteria after the operation. The visual analogue scale (VAS) for pain, lower extremity functional scale (LEFS), and self-rating anxiety scale (SAS) were used to evaluate the improvement of the quality of life of postoperative patients.Results:38 patients were followed up with a mean follow-up of 13.53±2.37 months. 37 patients' infections were effectively controlled, and 1 patient had a recurrence of infection, with an effectiveness rate of 97% for the treatment of McKee's infections. The preoperative calculated bone defect amount and soft tissue defect area were 51.05±26.31 cm 3 and 68.42±43.45 cm 2 respectively, and the actual measured values after debridement during the operation were 51.66±26.35 cm 3 and 68.82±43.76 cm 2 respectively. There was no statistically significant difference before and after the operation ( P>0.05). The interval between the first and second stage surgeries was 10.36±1.61 weeks, and all flaps survived after the first stage surgery. Two months after the operation, one case had recurrent osteomyelitis. After palliative treatment, sinus tracts were formed at the infection site. At the 12-month regular dressing change follow-up, there were still purulent secretions in the sinus tracts. There was no recurrence of infection after primary debridement in 37 cases, and the bone grafts healed. The bone healing time was 3.58±0.97 months. The postoperative VAS, LEFS, and SAS scores were 1.00±0.91, 66.68±7.91, and 34.30±4.29, respectively, which were significantly improved compared with the preoperative scores of 7.54±1.52, 21.22±4.29, and 52.70±6.74, respectively, and the difference was statistically significant ( P<0.05). Conclusions:The application of digital technology to precisely design the debridement range of bone and soft tissue, and the real-time holographic visualization monitoring of the debridement range during the operation can achieve precise debridement of bone and soft tissue and personalized and precise repair of soft tissue defects. It is a safe and effective technique for the treatment of chronic osteomyelitis of the tibia.

Moyamoya disease is a chronic progressive occlusive cerebrovascular disease characterized by progressive occlusion of the terminal internal carotid artery with formation of an abnormal vascular network at the skull base. The pathogenesis of the disease is not fully understood and is mainly thought to be associated with genetic factors, environmental factors and immune inflammatory response. The discovery of relevant biomarkers may provide hope for elucidation of pathogenesis of moyamoya disease and the early diagnosis and treatment of it. From the perspectives of coding gene, non-coding RNA and protein related to moyamoya disease, the possible molecular mechanisms involved in the occurrence and development of moyamoya disease are elaborated to further clarify their value as biomarkers of moyamoya disease.
