All symptoms resolved after treatment in the patients who had initially presented with mass effect. NLM Lanzino G, Wakhloo AK, Fessler RD, Hartney ML, Guterman LR, Hopkins LN. One was thrombosed, as shown by late control angiography; in the other one, a second larger bare stent was used to appose the stent graft's distal end to the ICA wall, thus sealing the endoleak into the distal graft. Surgery which required removal of the clinoid process was rather complex, and aneurysms within the cavernous segment were regarded by many as either unclippable or clippable given superb skill and acknowledgement of higher stakes.
