Thromboendarterectomy is a surgical procedure aimed at removing a thrombus, which can be a blood clot or atherosclerotic plaque, from the common femoral artery. This artery is a major blood vessel located in the thigh that supplies blood to the lower limb. The procedure is essential for restoring blood flow in cases where the artery has become occluded, which can lead to serious complications such as limb ischemia. During the operation, an incision is made in the leg to access the common femoral artery. The surgeon isolates the affected segment of the artery, carefully dissecting it from surrounding tissues. To maintain blood flow during the procedure, a temporary shunt may be placed. The surgeon then removes the obstructive material, including the artery's intima, which is the innermost layer of the artery wall. This removal is crucial as it helps to increase the diameter of the artery, facilitating better blood flow. After the thrombus and intima are excised, the remaining edges of the artery are sutured together, or a patch graft may be applied if necessary to further enlarge the artery. The procedure concludes with the removal of any temporary shunts, restoration of blood flow, and careful inspection of the surgical site to ensure there is no bleeding before closing the incision in layers.
