Covered stents to treat partial recanalization of onyx-occluded giant intracavernous carotid aneurysm.

Purpose: To present the application of a covered stent for the management of a left internal carotid artery (ICA) aneurysm that had recanalized following embolization with Onyx.

Case Report: A 54-year-old man had a giant intracavernous aneurysm of the left ICA successfully occluded with Onyx. Recurrence of symptoms 5 months later prompted control angiography, which showed partial recanalization of the aneurysm.

Percutaneous management of extensive clot trapped in a temporary vena cava filter.

Purpose: To present percutaneous management of extensive clot trapped in a temporary inferior vena cava (IVC) filter.

Case Report: A 20-year-old man with a large sacral tumor and left external iliac vein thrombosis had a wire-mounted Günther temporary filter (GTF) prophylactically placed in the infrarenal IVC prior to tumor resection. The 7-day postsurgical venogram prior to filter removal showed extensive clot trapped by the filter, as well as interval cephalic migration, with the filter tip now at the level of the renal veins.
