Objective To summarize the experience in treatment and diagnosis of popliteal artery trauma and to determine the factors for amputation. Methods From February 1995 to January 2006, 28 patients with popliteal artery trauma were treated. The disease course was more than 8 hours. Of them, there were 25 males and 3 females, aging from 3 to 53 years. Trauma was caused by traffic accident in 12 cases, by falling from height in 3 cases, by firearm in 2 cases, by sharp instruments in 3 cases, by strangulation in 2 cases and by others in 6 cases. No arteriopalmus or weak arteriopalmus wereobserved in 18 cases and in 8 cases respectively. Popliteal artery exposure or active bleeding was seen in 2 cases; the popliteal arteries were examined by operation in 8 cases; color ultrasound Doppler flow imaging showed color flood flowsignals were through popliteal artery and its branches in 20 cases. Defect sizeof popliteal artery was less than 5 cm in 7 cases and more than 5 cm in 9 cases. End to end anastomosis reconstruction by saphenous vein graft and direct suture was performed in 16 cases and ampulation in 12 cases. The time of the revascularization of the leg was 8-150 hours (mean 31.8 hours). Results All patients were followed up 6 months to 11 years with an average of 4.2 years. In 16 cases given end to end anastomosis reconstruction, 15 cases achieved revascularization and limb survival; lower limb function restored to normal within 1 year in 12 cases; foot drop and ankle joint contracture occurred in 3 casesand the survival rate of limbs was 94%. Amputation was given in 12 of 28 casesbecause of severe trauma. The rate of amputation was 43% and the rate of disability was 54%. Conclusion Popliteal artery trauma should be treated as soon as the diagnosis is made. If the revascularization is more than 8 hours or circulatory compensation is not complete, it will affect the leg survival. Delayed diagnosis and severe traumas are the cause of high rate ofamputation in popliteal artery trauma.
In recent years, with the continuous development and increasing maturity of interventional techniques, interventional treatment for congenital heart disease (CHD) has been progressively disseminated to county- and city-level hospitals in China. Concurrently, the standardized management of adult CHD (particularly patent foramen ovale) and the lifelong management of complex CHD are gaining increasing clinical attention, while the emergence of new techniques and products continuously advances the discipline. This article aims to review the new progress made in the field of interventional treatment for congenital heart disease in China during 2024. It specifically reviews and analyzes the following key aspects: (1) annual statistics on interventional closure procedures for CHD; (2) recent insights into patent foramen ovale closure; (3) advances in transcatheter pulmonary valve replacement; (4) interventional treatment and lifelong management strategies for complex CHD; (5) new interventional techniques for acquired heart disease; and (6) the application of artificial intelligence in CHD management. Through the synthesis and discussion of these topics, this article seeks to provide a detailed analysis of the current landscape of interventional treatment for CHD in China and project its future development trends.
