Abstract:Venous malformation (VM) is the most common type of congenital vascular anomaly, characterized by a lifelong progressive course that poses significant threats to patients"" physical and mental health. In terms of treatment, the innovative application of radiofrequency ablation (RFA) to VM has emerged as a reliable therapeutic option, demonstrating definitive clinical efficacy while offering advantages such as safety, minimal invasiveness, shorter hospital stays, and lower cost. Nevertheless, there is still no authoritative guideline or consensus, either from domestic or international sources, that provides standardized recommendations for RFA in the treatment of VM. To fill this void, the Emergency Medicine Branch of the Chinese Medical Association and the Interventional Physicians Branch of the Chinese Medical Doctor Association convened a multidisciplinary panel of experts from various fields that include vascular tumor surgery, vascular surgery, plastic surgery, interventional radiology, diagnostic imaging, emergency medicine, general surgery, and internal medicine. Drawing upon both domestic and international research, the panel reviewed and discussed recent advances and the clinical significance of RFA in VM treatment. As a result, they developed and refined the Expert Consensus on Radiofrequency Ablation for Venous Malformations (2025 version). This consensus includes 20 expert recommendations covering indications, ablation strategies, perioperative management, and approaches to the prevention and management of related complications. The aim is to enhance clinicians’ understanding and practical skills in the standardized application of RFA for VM, thereby ensuring its safety and effectiveness in clinical practice.

Abstract:Background and Aims: Laparoscopic anatomical liver segmentectomy has been widely applied in the surgical treatment of hepatic tumors due to its safety, feasibility, and effectiveness. The combination of indocyanine green (ICG) fluorescence-guided positive staining and intraoperative laparoscopic ultrasound has become an important technique for precision liver resection, particularly in accurately delineating hepatic segment/subsegment boundaries and achieving negative surgical margins. This study reports a case of anatomical resection of the right posterior segment and the dorsal subsegment of the right anterior segment of the liver, guided by laparoscopic ultrasound combined with ICG positive staining, to evaluate its clinical feasibility and outcomes. Methods: A retrospective analysis was conducted on an elderly female patient with a hepatic space-occupying lesion who underwent laparoscopic anatomical resection of the right posterior segment and right anterior dorsal subsegment using intraoperative ultrasound combined with ICG fluorescence-guided positive staining. Results: Preoperative three-dimensional reconstruction revealed that the tumor was located in the right posterior segment and right anterior dorsal subsegment. Intraoperatively, under laparoscopic ultrasound guidance, the anterior-ventral branch of the right portal vein was punctured and injected with ICG to achieve precise staining of the right anterior-ventral subsegment. The resection was performed along the fluorescent boundary, enabling accurate anatomical removal of the targeted liver segments. Intraoperative blood loss was approximately 100 mL without transfusion. Pathology confirmed a moderately differentiated small-duct type intrahepatic cholangiocarcinoma with negative margins (R0 resection). The patient recovered well and was discharged on postoperative day 19. Follow-up CT at 6 months showed no evidence of recurrence. Conclusion: During anatomical resection of the right posterior segment and right anterior dorsal subsegment of the liver, laparoscopic ultrasound combined with ICG fluorescence-guided positive staining can accurately define segmental boundaries, enhance surgical safety, and ensure complete tumor resection, thus offering significant value in achieving R0 resection.

Abstract:The incidence of chronic venous disease (CVD) is significantly higher in the elderly population compared to non-elderly individuals, with more severe disease manifestations. Additionally, elderly CVD patients often have comorbid conditions such as cardiovascular diseases, making the evaluation process more complex and increasing treatment difficulty. Currently, there are no established recommendations in China for the diagnosis and treatment of CVD in individuals aged 60 and above. Against this backdrop, the Peripheral Vascular Disease Management Branch of the Chinese Geriatric Society has developed the Chinese Expert Consensus on the Diagnosis and Treatment of Chronic Venous Disease in the Elderly based on domestic and international guidelines, relevant evidence-based medical research, and the physiological and clinical characteristics of the elderly population in China. This consensus aims to provide an important reference for improving the diagnosis and treatment of CVD in elderly patients in China.
