Prostatectomy in factor XI (plasma thromboplastin antecedent) deficiency.

A total of 10 patients with factor XI deficiency underwent prostatectomy: 3 who underwent suprapubic prostatectomy and 3 who underwent transurethral resection received fresh frozen plasma preoperatively, while 4 received fresh frozen plasma only in response to bleeding. We conclude that all patients who present with partial or severe factor XI deficiency should receive fresh frozen plasma preoperatively and for at least 10 to 14 days postoperatively. We believe that all Ashkenazi Jews who are about to undergo a urological operation should be screened for factor XI deficiency even when a history of a bleeding tendency is not present.
