To the Editor:—
In The Journal, Dec. 12, 1936, Collens and Wilensky, cited a case of thrombo-angiitis obliterans, No. 3 in their series, which was apparently healed, according to the illustration on page 1961. On page 1965 the statement is made "Of all the ulcers that have healed in our series, not one has subsequently broken down."It may be interesting to report that this patient, P. N., was examined at my office on Oct. 21, 1936, at which time there was an ulcer about 2 by 3 cm. in diameter on the stump of the left foot near the medial surface. According to the patient's statement, this ulcer had been present for a few weeks and showed no signs of healing although he has been using the Collens apparatus continuously. An oscillometric tracing taken on the same day showed no arterial pulsation whatever at the ankle level.
