Abstract
Coexistence of spinal arteriovenous malformation and aneurysm is quite rare. Eleven cases verified by angiography and/or operation had been reported so far in literature. The authors reported a case of cervical spinal arteriovenous malformation combined with aneurysm. This case was third case in Japan.
A 21 years old woman suddenly developed intractable headache with nuchal pain on May 13, 1976. Lumbar puncture showed blood in the cerebrospinal fluid. Positive neurological findings on admission were mild left-sided hemiparesis, diminished left biceps and triceps jerks, thermohypesthesia below L4 dermatome and urinary retention. Left vertebral angiography demonstrated typical arteriovenous malformation with fusiform aneurysm.
On June 17, clipping of feeding arteries, partial removal and obliteration through coagulation of arteriovenous malformation were performed by the use of operating microscope. Postoperative course was uneventful.
