Modified surgical concept for fulminant pulmonary embolism

Area of Science:

• Cardiovascular Surgery
• Pulmonary Medicine
• Critical Care Medicine

Background:

• Fulminant pulmonary embolism (PE) carries a high mortality rate, especially when cardiopulmonary resuscitation (CPR) is required.
• Surgical mortality in PE is often linked to persistent right heart failure and recurrent thromboembolism.
• Traditional surgical embolectomy methods have limitations in critically ill patients.

Purpose of the Study:

• To evaluate the effectiveness of a modified surgical strategy for emergency pulmonary embolectomy in patients with fulminant PE.
• To assess the impact of the modified technique on surgical mortality and patient outcomes.
• To compare the outcomes of the modified approach with the standard surgical method.

Main Methods:

• A cohort of 25 patients underwent emergency pulmonary embolectomy between 1988 and 1994.
• The standard approach involved central pulmonary artery incision and clot extraction.
• A modified strategy (since 1993) included peripheral pulmonary artery incision, selective desobliteration, and simultaneous clearance of major body veins.

Main Results:

• The standard approach had a 35% mortality rate, with higher mortality in patients operated on under CPR.
• The modified strategy was applied to 8 critically ill patients, 5 of whom were operated on under or after CPR.
• All 8 patients treated with the modified strategy survived, with some requiring caval filters for ongoing thrombotic disease.

Conclusions:

• The modified surgical strategy of selective pulmonary artery desobliteration and body vein clearance appears to reduce surgical mortality in fulminant PE.
• This approach may be particularly beneficial for high-risk patients, including those requiring CPR.
• Further investigation is warranted to confirm the benefits of this modified surgical technique.
