ABSTRACT
Objective:To compare the efficacy of catheter-directed thrombolysis versus catheter-directed thrombectomy for high-risk pulmonary embolism.Methods:The clinical data of 105 patients with high-risk pulmonary embolism from April 2020 to January 2023 in Hebei China Petroleum Central Hospital were retrospectively analyzed. Among them, 52 patients were treated with catheter-directed thrombolysis (thrombolysis group), and 53 patients were treated with catheter-directed thrombectomy (thrombectomy group). The efficacy, symptom relief time, oxygen saturation recovery time, mortality rate, Qanadli embolic index, pulmonary artery pressure and complications were compared between two groups.Results:There were no statistical differences in total effective rate, symptom relief time, oxygen saturation recovery time, mortality rate and total incidence of complications between two groups ( P>0.05). Compared with before treatment, the Qanadli embolic index and pulmonary artery pressure after treatment in thrombolysis group and thrombectomy group were significantly lower, thrombolysis group: 22.08 ± 8.57 vs. 45.18 ± 13.27 and (24.18 ± 5.19) mmHg (1 mmHg = 0.133 kPa) vs. (34.15 ± 6.22) mmHg, thrombectomy group: 23.11 ± 8.62 vs. 44.82 ± 13.14 and (23.66 ± 5.02) mmHg vs. (34.89 ± 6.27) mmHg, and there were statistical differences ( P<0.01); but there was no statistical difference the Qanadli embolic index and pulmonary artery pressure before and after treatment between two groups ( P>0.05). Conclusions:In patients with high-risk pulmonary embolism, both catheter-directed thrombolysis and catheter-directed thrombectomy have good efficacy and can promote the relief of clinical symptoms and the recovery of oxygen saturation, improving the prognosis.
