Compartment syndrome is a very rare complication of coronary artery bypass grafting and previously it has only been described unilaterally. We describe the development of compartment syndrome in bilateral anterior compartments of the lower leg after vein harvest for coronary artery bypass grafting. We describe a series of predisposing factors contributing to this condition and its delayed diagnosis, including severe undiagnosed hypothyroidism. We advise a high index of suspicion in patients postvein harvest and recommend thyroid function testing for all patients who have compartment syndrome develop.

Compartment syndrome is a limb-threatening condition often associated with traumatic, crush, burn, and reperfusion injuries. It is characterized by the development of disproportionately severe pain, paresthesias, decreased range of motion, loss of pulse, and a tense, edematous limb. In addition, measured compartment pressures and creatine phosphokinase values are often elevated. The definitive treatment is a decompressive fasciotomy. Compartment syndrome after coronary artery bypass grafting, however, is rare. The few reported cases all occurred in the vein donor leg after open harvest. We present a patient with compartment syndrome after endoscopic harvest of the saphenous vein for coronary artery bypass grafting.

Donor site morbidity for free fibula osteofasciocutaneous flaps has rarely been reported in the literature. We report on a case of acute compartment syndrome (ACS) in a 22-year-old male, following fibula flap harvest for mandibular reconstruction and arising after post-ischemic reperfusion damage. Dissection during this patient's surgery was unusually difficult. The skin defect was covered with a loose dressing while waiting for secondary grafting. Intracompartmental pressures measured by the Wick catheter technique confirmed the diagnosis of ACS. ACS is an unexpected complication after fibula flap harvest since the three compartments of the leg are opened during surgery. Only four cases of ACS have been reported in the literature. Analysis of this serious complication might lead to changes in the routine use of the pneumatic tourniquet in some selected cases. New automatic tourniquet systems might also be advantageous in such cases.
