Purpose:To determine if compression of the left common iliac vein (LCIV) by the right common iliac artery is associated with left-sided deep venous thrombosis (DVT). Materials and Methods:This Results:Patients with right DVT were more likely than those with left DVT to have a history of pulmonary embolism. Overall, in all study patients, mean percentage compression was 36.6%, 66 (29.7%) of 222 had greater than 50% compression, and 16 (7.2%) had greater than 70% compression. At most levels of compression, increasing compression was not associated with left DVT (adjusted ORs, 1.00, 0.99, 1.02) but above 70%, LCIV compression may be associated with left DVT (adjusted ORs, 3.03, 0.91, 10.15). Conclusion:Increasing levels of percentage compression were not associated with left-sided DVT up to 70%; however, greater than 70% compression may be associated with left DVT.q RSNA, 2012Supplemental material: http://radiology.rsna.org/lookup /suppl

Purpose: To assess long-term clinical efficacy of uterine artery embolization compared to abdominal myomectomy.Materials and Methods-Consecutive women who received either uterine artery embolization or abdominal myomectomy for symptomatic uterine leiomyomata between 2000 and 2002 at a single institution were enrolled. We include patients whose procedures were performed 5 years prior to the study. Symptom evaluations using symptom severity scores, pregnancy rates and satisfaction of the procedures were obtained by IRB-approved questionnaires. Chart reviews were performed to supplement analyses.Results-The retrospective cohort included 185 patients, including 87 uterine artery embolization patients (47.0%) and 98 abdominal myomectomy patients (53.0%). Eighty nine patients (48.1%) completed the long-term follow-up, of whom 48 had uterine artery embolization and 41 had abdominal myomectomy. Follow up ranged from 50 to 83 months.A higher but not statistically significant number of patients received repeat interventions after abdominal myomectomy (14%) than uterine artery embolization (8%) (p=0.204). Statistically significantly higher symptom severity score improvement in patients with uterine artery embolization than abdominal myomectomy was seen (34 vs 31, p = 0.02). Uterine artery embolization patients were less likely to attempt to get pregnant (p = 0.02), however those who did had a 66.7% success rate compared with 58.8% for abdominal myomectomy patients. Similar numbers of patients with uterine artery embolization were satisfied (p= 0.57), reported effectiveness in relieving symptoms (p=0.43), and would recommend the procedure (p=0.37) compared with abdominal myomectomy patients.Conclusion-Uterine artery embolization results in long-term clinical success with outcomes comparable or superior to abdominal myomectomy.
