Abstract:
Objective To evaluate the application value of aspiration catheter and debulking technology in the treatment of patients with intermediate-and high-risk pulmonary thromboembolism(PTE).Methods The clinical data of 28 patients with intermediate-and high-risk PTE were analyzed retrospectively.All subjects received thrombectomy using a 7F JR Guiding catheter.The success rate of surgery and the incidence of complications were counted,and the preoperative and postoperative values in heart rate(HR),systolic blood pressure(SBP),oxygen saturation(SO2),partial pressure of oxygen(PO2),Miller index,and mean pulmonary arterial pressure(MPAP)were compared.Results All patients were successfully treated,of which 26 cases obtained symptomatic relief after surgery.There were 2 cases of death in high-risk patients,of whom one died of myocardial infarction,and the other died of cerebral herniation after the procedure.One case reported the formation of pulmonary artery small dissection which disappeared within 2 months during conservative observation.The postoperative HR,Miller index,and MPAP decreased and SBP,SO2,and P()2 increased significantly than those of preoperative(P＜0.05).The follow-up period for this group ranged from 7 to 29 months,with a median follow-up of 14.6(7,19)months.During the follow-up period,no recurrences were observed.Conclusion The aspiration catheter and debulking technology demonstrate efficacy in treating intermediate-and high-risk PTE,and is associated with favourable success rates and low complication rates.The findings suggest its potential for wider clinical use.
