Transcatheter embolization of a superior mesenteric artery pseudoaneurysm. A case report

A 61-year-old man, with pseudoaneurysm of the superior mesenteric artery presenting with gastrointestinal bleeding, was successfully treated by transcatheter embolization using interlocking detachable coils. During the following observation time of 10 months, the patient had no sign of gastrointestinal bleeding. We underline the importance and feasibility of transcatheter embolization as the first-line treatment in such pseudoaneurysms.

Preoperative embolization of meningiomas with pial supply: successful treatment of two cases

BACKGROUND

The efficacy of preoperative embolization for hypervascular meningiomas fed by the pial branches of the internal carotid artery was evaluated.

METHODS

Two cases of hypervascular meningiomas fed by the cortical branches of the internal carotid arteries are presented. In the first patient, the left anterior frontal internal artery was embolized with gelatin sponge (Gelfoam) as a preoperative treatment using a microcatheter. The tumor was totally resected with 1,000 ml of blood loss. In the second patient, the right sulcal artery was embolized with Gelfoam. The patient subsequently underwent surgical resection with 100 mL of blood loss.

RESULTS

No neurological deficit appeared after the embolization or the surgery in either case.

CONCLUSION

Preoperative embolization of hypervascular meningiomas, mainly fed by the cortical branches of the internal carotid arteries, may be possible and effective.
