[Unusual postoperative hemorrhage in a patient with ruptured aneurysm and hemophilia B].
A case of ruptured cerebral aneurysm with hemophilia B is reported, and discussion is made concerning the management of mild type hemophilia in surgical operations. A 41-year-old male came to our hospital with complaints of severe headache, vomiting, and transient consciousness disturbance. His dentist said the patient had a mild bleeding tendency when he was 30 years old, however no postoperative hemorrhage was repeated in appendectomy in his childhood. He also had had no episodes of spontaneous bleeding. CT scan on admission showed subarachnoid hemorrhage, and angiography revealed a ruptured aneurysm at the trifurcation of the left middle cerebral artery. His coagulation screening tests (bleeding time, clotting time, prothrombin time, and activated partial thromboplastin time) were normal. An aneurysmal neck clipping was carried out, and operators did not detect any bleeding tendency during the surgery. CT scan on the next day showed no remarkable finding. On the third postoperative day, right hemiparesis occurred. Left putaminal hemorrhage took place. His coagulation tests and FDP were also normal. The hematoma was partially evacuated. After the second operation his condition was good, and rehabilitation program started. On the 15th hospital day his consciousness deteriorated suddenly, and CT scan showed a massive epidural hematoma on the left. His prothrombin time elongated mildly, but other tests were normal. Coagulation factors VIII and IX were examined and the factor IX was 22.5% of control. He was thought to be a patient with mild type hemophilia B. Despite a third operation for hematoma removal he died on the 20th hospital day. Mild type hemophilia B does not bleed spontaneously.(ABSTRACT TRUNCATED AT 250 WORDS)
