Objective:To summarize and analyze the modalities and experience of retrograde distal perfusion with distal perfusion catheter (DPC) via cannulation of the posterior tibial artery in veno-arterial extracorporeal membrane oxygenation(V-A ECMO).Methods:The clinical data of 15 patients who were treated with V-A ECMO and underwent DPC placement via the posterior tibial artery in our hospital from January 2022 to June 2023 were retrospectively analyzed.Results:The V-A ECMO catheterization method in 15 patients was percutaneous puncture catheterization, and all of them underwent surgical incision to indwelling retrograde DPC through the posterior tibial artery: 6 cases of preventive catheterization, 9 cases of remedial catheterization, the success rate of one-time catheterization was 93.33%, and the type of catheter was mainly 6 F sheath (66.67%). There was no ALI in preventive catheterization, and one case of osteofascial compartment syndrome occurred in remedial catheterization, and the catheterization time was (20.73 ± 3.47) min.Conclusions:In V-A ECMO, placement of DPC via the posterior tibial artery for retrograde distal perfusion is perfectly feasible, and has a high success rate, which can prevent or treat lower extremity ischemia.

Objective:We undertook this trial to assess the status quo of quality of life(QOL) among patients of tota1 laryngectomy,hemilaryngectomy and nasopharyngeal carcinoma undergoing radiotherapy and chemotherapy. Methods:Head-neck carcinoma patients were divided into three groups according to the types of diseases. Using UW-QOL questionnaire and some special questions consistent with local conditions,a survey was conducted in 41 head-neck carcinoma patients more than 2 months after operation or radiotherapy and chemotherapy. Results:The scores of total quality of life were 652.083?160.560,768.067?116.749,and 700.732?1.204,there were significant differences among three groups in aspects of recreation,communication and swallowing function(P
