Fig 3. — Pre- and postprocedural DSA and follow-up MR imaging and conventional angiography images of a 43-year-old female patient with a left MCA aneurysm. A, Preprocedural DSA image obtained at a left anterior oblique projection shows an 8-mm bilobed aneurysm located in the left MCA bifurcation. B, Intraprocedural roadmap DSA image shows the catheterization of the inferior trunk of the MCA (black arrows) and jailing of another microcatheter in the aneurysm sac (white arrows). C and D, Intraprocedural DSA images reveal complete occlusion of the superior lobule of the aneurysm after stent placement of the inferior MCA trunk (black arrows show the extension of the stent) and selective catheterization of the inferior lobule of the aneurysm for coiling. E, Immediate postprocedural DSA image demonstrates complete occlusion of the aneurysm. F, Three-month follow-up MR angiography image in a submentovertical projection demonstrates complete occlusion of the aneurysm and patency of the parent artery (arrows). G, Six-month follow-up conventional angiographic image shows complete stable occlusion of the aneurysm.
