To the editor: Suchman and Griner (1) conclude that the activated partial thromboplastin time adds "no information to the preoperative care of patients without clinical findings indicative of increased bleeding risk." They recommend that screening should be done only for procedures that interfere with hemostasis, such as transurethral prostatectomy. We want to emphasize this latter point.
Of 24 patients with factor XI deficiency in our report (2), 5 had abnormal bleeding after prostatectomy. In 4 of them, postoperative bleeding led to the diagnosis of factor XI deficiency. In the fifth patient, hematuria after a retropubic prostatectomy persisted for 1 month
