Abstract
The two patients with ruptured vertebral-posterior inferior cerebellar artery junction aneurysm (VA-PICA AN) with paraparesis are reported.
One was a female patient of 58-year-old, whose onset was headache, nausea, vomiting and conciouslessness. And she presented paraparesis and abducens paresis. A CT scan revealed severe subarachnoid hemorrhage (SAH), and a four-vessel study showed Rt. VA-PICA AN. Six days after aneurysm rupture, neck ligation & clipping were performed. After the operation, paraparesis was improved by degrees.
Another case was 61-year-old, whose onset was conciouslessness. And she presented tetraparesis (leg>arm), and had severe SAH and Rt. VA-PICA AN. Three days after the operation, tetraparesis was improved by degrees.
Paraparesis was not recognized as a specific symptom of VA-PICA AN. There is only one report that presents paraparesis with VA-PICA AN, however, two cases of symmetric paraparesis were picked up, which might occur on condition that an aneurysm was located at the center of medulla oblongata and that the direction of an aneurysm was upward and backward.
