Objective To review the clinical progress of microsurgical management for lymphedema. Methods The literature on microsurgical treatment for lymphedema at home and abroad in recent years was reviewed and analyzed. Results At present, conservative treatment is the main treatment for lymphedema, which has limited effectiveness only for early stages of lymphedema; and it is not curative and demands patient compliance. In contrast, microsurgical approaches can solve the problems in the prevention or management of lymphedema and showed promising results, such as lymphatic-venous anastomosis (LVA), vascularized lymph node transfer (VLNT), and other lymphatic reconstructions. Conclusion Microsurgical approaches like LVA and VLNT have been broadly used in recent years, the effectiveness and safety have been proved. But the evidence of long-term randomized controlled studies is still required to establish standard treatment practices.
ObjectiveTo explore the short-term efficacy and safety of Ozaki surgery in treating adult patients with aortic valve disease and to summarize clinical experience. MethodsClinical data of adult patients with aortic valve disease who underwent Ozaki surgery in the Department of Cardiovascular Surgery, Beijing Anzhen Hospital of Capital Medical University Nanchong Branch in 2025 were collected, and the effectiveness and safety of Ozaki surgery were analyzed. ResultsA total of 5 patients were included, including 3 males and 2 females, with an average age of (47.80±12.99) years. One patient was aortic stenosis, 2 patients were aortic regurgitation, and 2 patients were aortic stenosis combined with regurgitation. Two patients underwent isolated Ozaki surgery, 1 patient underwent Ozaki+coronary artery bypass surgery, and 2 cases underwent Ozaki+mitral valve plasty+tricuspid valve plasty. The average operation time was (6.70±1.25) hours. The average extracorporeal circulation time was (217.20±59.47) minutes, the average aortic cross-clamping time was (153.60±45.71) minutes, the average postoperative ventilator support time was (25.00±11.79) hours, the average intensive care unit stay was (2.43±1.30) days, and the average postoperative hospital stay was (11.20±1.92) days. The postoperative average aortic valve flow rate was (1.70±0.26) m/s, and the average transvalve pressure gradient was (11.00±1.87) mm Hg. Postoperatively, 3 patients had no aortic regurgitation, and 2 patients had trace regurgitation. Postoperative complications included pulmonary infection in 3 patients, severe pneumonia in 1 patient, liver function damage in 4 patients, and renal function damage in 3 patients. No patients experienced arrhythmias or other complications. All 5 patients recovered and were discharged, and their cardiac function significantly improved postoperatively compared to preoperatively (P<0.001), with both left ventricle (P=0.047) and left atrium (P=0.016) reduced in size. ConclusionThe short-term results of Ozaki surgery for adult patients with aortic valve disease are satisfied, but long-term outcomes still need further exploration.
