Compartment syndrome of the lower leg after surgery in the modified lithotomy position: report of seven cases.

PURPOSE: Acute compartment syndrome is known to develop after trauma or after postischemic revascularization. It also can occur when a patient has been lying in the lithotomy position during prolonged surgery. Methods were searched for the prevention of this iatrogenic complication after a series of seven patients who developed compartment syndrome after surgery at our hospital.

METHODS: A series of seven consecutive patients who developed compartment syndrome of the lower leg(s) after abdominoperineal surgical procedures from 1997 to 2002 is presented and so are the lessons learned to prevent this problem.

RESULTS: When comparing our experiences with data from literature, the seven patients had the usual risk factors for development of a compartment syndrome: lengthy procedure (>5 hours); decreased perfusion of the lower leg because of Trendelenburg positioning combined with the lithotomy position; and external compression of the lower legs (because of positioning, stirrups, or antiembolism stockings). Measures have been taken to prevent compartment syndrome from developing after prolonged surgery in the lithotomy position. This complication has not occurred again after the introduction of these measures two years ago.

CONCLUSIONS: Acute compartment syndrome can be prevented if adequate measures are taken, but after lengthy surgery, maximum alertness for emerging acute compartment syndrome remains indicated. Early diagnosis and treatment by four-compartment fasciotomy is still the only way to prevent irreversible damage.
