The effects of restoring arterial patency on various noninvasive measurements of hemodynamic function (pedal blood pressure, transcutaneous oxygen, laser-Doppler measurements of skin blood flow, skin temperature, and total limb blood flow) were determined before and serially after the successful surgical revascularization of an ischemic lower limb (n = 10). All measured hemodynamic end points improved immediately (at 24-36 hr) following surgery, but the magnitude of the changes differed considerably among the various tests. During serial in-hospital follow-up studies (at 3-4 and 7-10 days postoperatively) the majority of the end points continued to improve. We conclude: (1) all the testing modalities evaluated in this study can be used to assess changes in limb hemodynamics following arterial revascularization; (2) different tests may give quantitatively different results; and (3) during the 7-10-day postoperative period, most hemodynamic end points continue to improve. Assessments based upon measurements made during the first postoperative day may therefore underestimate the ultimate extent of improvement.
