Pulmonary embolectomy: recommendation for early surgical intervention.

BACKGROUND

Acute pulmonary embolism (PE) is a life-threatening disease which often results in death if not diagnosed early and treated aggressively. Despite all efforts at improving outcomes, there is no consensus on the management of acute severe PE.

METHODS

From May 2000 to June 2009, 16 consecutive patients underwent surgical pulmonary embolectomy at our institution. Mean age was 45 +/- 17 years (range, 14 to 76) with nine (56%) males and seven (43%) females. Preoperatively, all cases were classified as massive PE; seven (43%) patients were in hemodynamic collapse and emergently underwent operation while receiving cardiopulmonary resuscitation.

RESULTS

There were nine (56%) urgent/emergent and seven (44%) salvage patients undergoing surgical pulmonary embolectomy. Of nine nonsalvage patients, seven (77%) patients presented with moderate to severe right ventricular (RV) dilation/dysfunction. Mean cardiopulmonary bypass time was 43 +/- 41 minutes (range, 9 to 161). Mean follow-up duration was 48 +/- 38 months (range: 0.3 to 109), with seven in-hospital deaths (43%): mortality was 11% (1/9) in emergent operations and 85% (6/7) in salvage operations.

CONCLUSIONS

Surgical pulmonary embolectomy should be considered early in the management of hemodynamically stable patients with PE who show evidence of RV dilation and/or failure, as it is associated with satisfactory outcomes. Conversely, pulmonary embolectomy has dismal results under salvage conditions. Revision of current guidelines for the surgical management of this condition may be warranted.
