Figure 1.

Left: Left vertebral artery injection through the guide catheter demonstrated complete occlusion of the basilar artery. Centre: The microcatheter and the microwire were navigated to the P1 segment of the right posterior cerebral artery; however, selective injection through the microcatheter showed contrast extravasation due to perforation/dissection of the arterial wall. Right: As a consequence, an important subarachnoid haemorrhage developed, with hydrocephalus.
