Segmental transcutaneous measurements of PO2 in patients requiring below-the-knee amputation for peripheral vascular insufficiency
EM Burgess, FA Matsen, CR Wyss and CW Simmons
An accurate method is needed to quantitate the healing potentials of the
possible sites of amputation in dysvascular limbs. We evaluated the
segmental transcutaneous measurements of PO2 in thirty-seven patients who
required below-the-knee amputation because of peripheral vascular
insufficiency. The fifteen patients with below-the-knee transcutaneous PO2
values of forty millimeters of mercury or more had no delay in healing of
the below-the-knee amputation. Seventeen of nineteen patients with values
of more than zero but less than forty millimeters of mercury had healing at
the below-the-knee level, in two after local revision. The three patients
who had below-the-knee values of zero required re-amputation above the
knee.
