Fig 3. A, Frontal angiogram from patient 1. The occlusion of the distal M1 segment is apparent and, as will be seen later on the post-treatment frontal image (F), covers the most lateral lenticulostriate artery.
B, The magnified frontal working view. Images C–E are made at this working projection.
C, We place the microcatheter tip at the point of obstruction.
D, The ARD is extended 3 mm beyond the catheter tip
E, Both microcatheter and device are withdrawn about 2 cm. Injection of contrast agent shows reperfusion of the distal vessels.
F, The pretreatment angiogram (A) can be compared with the posttreatment injection. Because the striate artery was covered, the patient developed a small capsular infarction.
