Mechanical thrombectomy resulted in similar rates of in-hospital death, significant bleed, vascular complication, or mechanical support compared to catheter directed lysis (11% vs 12%, p=0.5).

Does mechanical thrombectomy improve in-hospital outcomes compared to catheter directed thrombolysis in patients with acute pulmonary embolism?
Mechanical thrombectomy and catheter-directed thrombolysis have similar in-hospital safety and efficacy profiles for acute pulmonary embolism, though mechanical thrombectomy may reduce ICU length of stay.
Absolute Event Rate: 11% vs 12%
p-value: p=0.5
OBJECTIVES: Compare in-hospital outcomes of patients treated with either mechanical thrombectomy (MT) or catheter directed lysis (CDL) in treatment of acute pulmonary embolism (PE). METHODS: This is a multicenter, retrospective cohort study of patients undergoing MT or CDL for acute PE between 2014 and 2021. The primary outcome was the composite of in-hospital death, significant bleed, vascular complication, or need for mechanical support post-procedure. Secondary outcomes included the individual components of the composite outcome in addition to blood transfusions, invasive hemodynamics, echocardiographic data, and intensive care unit (ICU) utilization. RESULTS: 458 patients were treated for PE with 266 patients in the CDL arm and 192 patients in the MT arm. The primary composite endpoint was not significantly different between the two groups with CDL 12% versus MT 11% (p = 0.5). There was a significant difference in total length of ICU time required with more in the CDL group versus MT (3.8 ± 2.0 vs. 2.8 ± 3.0 days, p = 0.009). All other secondary end points showed no significant difference between the groups. CONCLUSIONS: In patients undergoing catheter directed treatment of PE, there was no difference between MT and CDL in terms of in-hospital mortality, bleeds, catheter-related complications, and hemodynamics.
Inci et al. (Wed,) conducted a cohort in Acute pulmonary embolism (n=458). Mechanical thrombectomy vs. Catheter directed lysis was evaluated on Composite of in-hospital death, significant bleed, vascular complication, or need for mechanical support post-procedure (p=0.5). Mechanical thrombectomy resulted in similar rates of in-hospital death, significant bleed, vascular complication, or mechanical support compared to catheter directed lysis (11% vs 12%, p=0.5).
