Brachial artery rupture complicating a pregnancy with neurofibromatosis: a case report.

A 30-year-old black woman was first seen at 34 weeks' gestation with pain in the right arm, which was already afflicted with neurofibroma. She was in hypovolemic shock on presentation, and after she was resuscitated, a live infant was delivered. The patient was diagnosed with a pseudoaneurysm of the right brachial artery with extravasation of blood in the interstitium of the arm. Although there have been other reported cases of arterial rupture in pregnancies with neurofibromatosis, the report of brachial artery rupture in this situation is believed to be the first documented case.
