Preprocedural cranial CT and procedural and follow-up angiography images of a 44-year-old female patient with a ruptured PICA aneurysm. A, Cranial CT image obtained 9 days before the endovascular procedure (5 days following the rupture of aneurysm) shows the subarachnoid hemorrhage in the prepontine cistern. B, DSA image in a right anterior oblique projection reveals a 5-mm wide-neck aneurysm located on the medullary segment of the left PICA. C, DSA images obtained during the procedure show the catheterization of the parent artery for stent placement (black arrows) from the contralateral (right) vertebral artery and jailing of the coiling microcatheter (white arrows) through the ipsilateral (left) vertebral artery (the small filling defect in the aneurysm sac is a small air bubble introduced by the delivery of coil and trapped between the coil loops). D, DSA image obtained during the procedure shows the successful deployment of a LEO Baby stent (arrows) into the parent artery (PICA–vertebral artery). E, Immediate postprocedural DSA demonstrates the near-total occlusion of the aneurysm, with minimal filling in the neck. F, Six-month follow-up DSA shows complete occlusion of the aneurysm and a moderate degree of in-stent stenosis.
