Pulmonary embolism after combined abdominoplasty and flank liposuction: a correlation with the amount of fat removed.
BACKGROUND
We prospectively followed patients who underwent esthetic abdominoplasty and flank liposuction to determine the influence of the amount of fat removed on the occurrence of pulmonary embolism.


METHODS
We recruited patients undergoing abdominoplasties and flank liposuction and composed 2 groups according to the amount of fat removed, one of small resections (<1500 g) and the other of great resections (>1500 g). All patients received deep vein thrombosis prophylaxis.


RESULTS
Since January 2005, we enrolled 103 patients and registered 3 embolisms (2.9%). All occurred in nonsmokers, had no risk factor for deep vein thrombosis, and a resection weight greater than 1500 g (21.4%; 3/14). The calculated relative risk conferred by the amount of fat greater than 1500 g was 7.4. An association was also found with duration of surgery: all embolisms occurred in patients that underwent long operation (>140 minutes; 8.8%; 3/34) with a relative risk of 3.0.


CONCLUSIONS
The amount of fat removed during plastic surgery is a factor influencing the occurrence of pulmonary embolism in patients undergoing abdominoplasty/flank liposuction, and the duration of surgery is a concomitant factor. Should this data be confirmed, specific measures for prevention of this serious complication could be developed.
