[99mTC-HSA lymphoscintigraphy and leg edema after arterial reconstruction].
To investigate the etiology of lower limb edema after arterial reconstruction, 12 patients (16 limbs) who underwent arterial reconstruction due to atherosclerosis obliterans were observed. There was no relationship between the severity of limb edema and serum factors (serum total protein, albumin, BUN and creatinine), ankle/brachial arterial pressure ratio, peripheral venous pressure or RI lymphoscintigraphy in the supine position. ⋯ Increased lymphatic flow in the follow-up period was associated with increased severity of leg edema in the upright position. It is concluded that postoperative leg edema is due to the damage to the lymphatic vessels during operation, and then the lymphatic channels cannot adapt to the increased lymphatic flow after the arterial reconstruction.
