Abstrakt:	Until now, 9 cases of an association of a posterior inferior cerebellar artery (PICA) aneurysm with the persistent primitive hypoglossal artery (PPHA) have been reported. We reported a case of a ruptured PICA aneurysm associated with the PPHA, which was successfully treated by intravascular embolization using inflation of an endovascular occlusion balloon in the proximal artery to stabilize the microcatheter tip. A 19-year-old woman presenting headache and mild consciousness disturbance was admitted to our hospital. Head computed tomography (CT) showed a subarachnoid hemorrhage in the interpeduncular cistern. Right common carotid angiography revealed an aneurysm with a maximum diameter of 3.7 mm at the proximal PICA, which was fed from the common carotid artery (CCA) through the internal carotid artery (ICA) and the PPHA and the vertebral artery. During coil embolization, a pulsatile fluctuation of the microcatheter tip caused by the minimum curvature of the proximal arterial route from the aorta to the PPHA made the continuation of the coil embolization difficult. Then, we inflated an occlusion balloon in the PPHA to stabilize the microcatheter tip, and the coil embolization was performed under the blank roadmap fluoroscopy. The aneurysm disappeared completely with the preservation of the PICA on the postoperative angiogram. A case of ruptured PICA aneurysm with proximal PPHA, which was successfully embolized with the assist of a proximal occlusion balloon inflation. When the pulsative movement of a microcatheter tip made coil embolization difficult, this technique could be useful. (© 2023 The Authors.
