Case Reports Comparative Study Clinical Trial
[Endovascular treatment of cerebral vasospasm with intra-arterial papaverine infusion].
Thirty-one cases of cerebral vasospasm following subarachnoid hemorrhage were treated with intraarterial papaverine infusion. Symptomatic cases were nineteen, and asymptomatic cases were twelve. Papaverine (120 mg/saline 50 ml, 30 min) was injected superselectively to vasospastic vessels through a microcatheter. ⋯ Overall outcome was ADL1 (19%), ADL2 (25%), ADL3 (44%), ADL4 (0%), ADL5 (6%), and death (6%). Since the effect of intra-arterial papaverine infusion is of short duration and weak, combination of PTA and papaverine may be necessary. It is recommended to use papaverine for vasospasm in distal arteries such as M2, A1, A2, and to carry out PTA for proximal arteries such as ICA and M1.

Acute extradural hematoma, a collection of blood between the inner table of the skull and the dura, generally occurs in coup craniocerebral trauma with skull fracture. We report here a case of a 52-year-old female who had had a traffic accident. She suffered a serious wound consisting of a subcutaneous hematoma with skull fracture and so called Battle's sign on the left occipital region but not wounded in any other region. ⋯ After the operation, the patient recovered consciousness. Contrecoup acute extradural hematoma is very rare. It seems that the appearance of hematoma in our case resulted from the frontal dural separation due to distortion of the cranium brought on by the force of the impact and the subsequent gradual growth of the hematoma under the stimulation of several bouts of vomiting.
