embolectomy
[em′bəlek′təmē]
Etymology: Gk, embolos, plug, ektomē, excision
a surgical incision into an artery for the removal of an embolus or clot, performed as emergency treatment for arterial embolism. The operation is done as soon as possible after a decrease in perfusion is detected. Thrombi tend to lodge at the juncture of major arteries. More than half lodge in the aorta, in arteries of the lower extremities, in the common carotid arteries, or in the pulmonary arteries. Before surgery, heparin may be administered, and an arteriogram may be used to identify the affected artery. A longitudinal incision is made in the artery, and the embolus is removed. After surgery the blood pressure is maintained close to the level of the preoperative baseline, as a decrease might predispose to new clot formation.
