The success of an embolectomy depends on: (1) early operation, (2) direct and adequate exposure of the site of embolism, (3) occlusion of the artery distal to the embolus before the artery is disturbed at, or proximal to, the site of embolism, (4) avoidance of damage to the intima, (5) complete control of the arterial inflow both proximal and distal to the arteriotomy so that (6) a meticulous intima-to-intima closure may be accomplished. The removal of a saddle embolus at the bifurcation of the aorta is a feasible operation if these principles are followed. The technique of the operation has been simplified by the use of the tourniquet type of clamp for control of the arteries during the embolectomy. A saddle embolus at the bifurcation of the aorta may be removed readily through an arteriotomy of the right common iliac artery, with two clamps on this blood vessel and one on the left common iliac artery, without the necessity of freeing up the aorta. Embolectomy is more readily accomplished by direct exposure of the site of embolism. For this reason a transperitoneal or extraperitoneal approach through a right paramedian incision is recommended for the exposure of the bifurcation of the aorta and the common iliac arteries.

SC. 209: 478, 1945. An objective method is described by which one can predict whether a collateral circulation is likely to develop following a major peripheral arterial occlusion and whether a sympathetic ganglionectomy is indicated. By determining the patient’s basal vascular tone, which can be obtained from any unoccluded extremity, it is possible to predict far more accurately the course of the disease and to decide the amount and type of treatment required. Patients who have a low grade of vascular tone will develop a collateral circulation almost invariably and, as a rule, do not require much treatment. The majority of patients who have a high grade of vascular tone do not develop a collateral circulation; and, since their symptoms are much more severe, require intensive treatment. Only patients with a high grade of vascular tone require sympathetic ganglionectomy. The previous method for selecting patients for sympathectomy on the basis of their capacity to vasodilate in response to paravertebral or local nerve block is erroneous. The patients who are in most urgent need for sympathectomy are those with high basal vascular tone who do not respond to temporary nerve block. Patients with low vascular tone are not improved by sympathetic ganglionectomy. AUTHORS.
