Uterine artery embolisation for uterine fibroids using a 4F Rosch inferior mesenteric catheter.

PURPOSE: To evaluate in a prospective study the use of a 4F Rosch inferior mesenteric (RIM) catheter for uterine artery embolisation (UAE). MATERIALS AND METHODS: UAE was performed in 72 women over a 37-month period. A 4F RIM braided J-curve 65-cm catheter was used in combination with an angled hydrophilic 150 cm, 0.035" flexible tip guide-wire to catheterise the horizontal portion of both uterine arteries (UA) from a right common femoral artery (CFA) approach. Technical success was defined as successful catheterisation and embolisation of both uterine arteries. Fluorosocpic and procedure times were recorded. RESULTS: Mean subject age=43.7 years (range=25-57 years). Technical success was 98.6% (n=71/72). A single approach via the right CFA was used in 88.9% (n=64/72) and a bilateral CFA approach in 11.1% (n=8/72). Bilateral uterine artery catheterisation using a single 4F RIM catheter via the right CFA approach was successful in 79.2% (n=57/72). Microcatheters were used in 2.8% of patients (n=2/72). Mean fluoroscopic time=13.6+/-5.3 min (mean+/-SD). Mean procedure time=44.2+/-16.5 min. CONCLUSION: High technical success rate for UAE is possible using a single 4F RIM catheter via a unilateral right CFA approach, which obviates the need for Waltman loop formation, reversed curve catheters and complex suture-catheter arrangements.

Polypoid arteriovenous malformation of colon mimicking inflammatory fibroid polyp.

Arteriovenous malformation is a well-known cause of lower gastrointestinal bleeding in the elderly and usually appears as flat or elevated bright red lesions endoscopically. Here we present a 59-year-old woman with a large fungating polypoid mass in the transverse colon. Histologically, the larger vessels were located mainly in the submucosa, and smaller vessels were also observed within the mucosa. Verhoeff's elastic stain showed internal and external elastic lamina in the malformed vessels. We report an extremely rare case of a large, pedunculated, polypoid arterioveneous malformation with the first description of our complete pathological findings.
