Incidental detection of an intracardiac cement embolism complicating percutaneous vertebroplasty during cardiac catheterization: A case report.

Percutaneous vertebroplasty has emerged as an increasingly popular intervention for managing a variety of common spinal conditions. Nevertheless, kyphoplasty cement can accidentally leak into paravertebral venous plexus, then travel to the right heart chambers through the venous system. We report an exceedingly rare case of an intracardiac cement embolism, likely an inadvertent complication of a recent percutaneous lumbar vertebroplasty. A mobile mass was incidentally found during a cardiac catheterization procedure, most likely in right atrium. Subsequent computed tomography angio chest and cardiac imaging confirmed a floating foreign body in the right atrium, which was then retrieved successfully through an endovascular approach. Gross examination of the removed body confirmed a bone cement-like material. Intracardiac cement embolism warrants serious attention as it may result in catastrophic cardiac complications. Learning objective: Intracardiac cement embolism is an extremely rare, but potentially life-threatening complication after percutaneous vertebroplasty. The bone cement fragments accidentally leak into paravertebral plexus and then via venous system into the right-sided cardiac chambers and pulmonary arteries.

Comparison of endovascular and open repair of ruptured abdominal aortic aneurysm in the United States in the past decade.

PURPOSE: The purpose of this study is national-level comparison of the endovascular (EVAR) and open repair (OAR) of ruptured abdominal aortic aneurysm (AAA) in the United States from 2001 to 2010. METHODS: The data were obtained from nationwide inpatient sample from the Department of Health and Human Services. Ruptured AAA treated by OAR or EVAR were selected using combination ICD-9 codes. RESULTS: There were 42,126 cases of ruptured AAA of which 8,140 (19.3%) were repaired by EVAR. EVAR patients were older (74.1 vs. 72.8 years, p < 0.001) and had higher incidence of comorbidities compared with OAR group. EVAR patients had lower in-hospital mortality (25.9 vs. 39.1%, p < 0.001) and shorter hospital stay (10.4 vs. 13.7 days, p < 0.001). More patients were discharged home following EVAR (36.8 vs. 21.5%, p < 0.001). There was reduced need for institutional rehabilitation following EVAR (26.3 vs. 29.1%, p < 0.001). Females had significantly higher mortality compared with males after both EVAR (32.2 vs. 24.1%, p < 0.001) and OAR (46.2 vs. 36.9%, p < 0.001). The hospital mortality (41.3-25.8%, p < 0.001) and mean length of stay (11.8-9.7 days, p < 0.01) of EVAR steadily improved over the study period. CONCLUSIONS: National level comparison of data from the past decade shows that in suitable cases, EVAR for ruptured AAA is associated with reduced hospital mortality, shorter hospital stay, and reduced need for rehabilitation. EVAR outcomes showed consistent improvement with time. Regardless of the type of repair, women had higher mortality compared with men.

Uterine artery embolization and its effect on fertility.

A systematic review of literature analyzing fertility following uterine artery embolization (UAE) is presented. Twenty-one studies describing pregnancy and complications of pregnancy following UAE were included. Low-level evidence from these studies suggests that pregnancy rates following UAE are comparable to the age-adjusted rates in the general population. Although pregnancy complication rates were similar to those in patients with untreated fibroid tumors, a few studies have reported higher miscarriage rates following UAE. Further randomized controlled trials comparing UAE versus other fertility-preserving treatments are necessary to confirm these findings.

Nationwide trends in abdominal aortic aneurysm repair and use of endovascular repair in the emergency setting.

PURPOSE: To analyze nationwide trends in abdominal aortic aneurysm (AAA) repair and the use of endovascular abdominal aortic aneurysm repair (EVAR) in the emergency setting. MATERIALS AND METHODS: Data were obtained from the Nationwide Inpatient Sample (NIS) using the International Classification of Diseases, Ninth Revision-Clinical Modification (ICD-9-CM) codes for open and endovascular repairs from 2001-2009. Trends in outcome parameters and hospital charges were compared. RESULTS: The number of emergency EVAR procedures increased from 382 in 2001 to 1,247 in 2009 (P < .001). During the study period, length of hospital stay associated with total number of EVAR procedures decreased from 3.8 days to 3.4 days (P < .05), and the in-hospital mortality decreased from 2.4% to 2% (P = .32). From 2001-2009, mean hospital charges associated with EVAR increased from $50,630 to $91,401 (74% increase), whereas charges associated with open repairs increased from $54,578 to $128,925 (136% increase). The proportion of patients needing rehabilitation or nursing home placement after EVAR increased from 5.8% to 7.7% (P < .01), and need for home health increased from 6.9% to 10.5% (P < .01). CONCLUSIONS: There was a significant increase in the number of emergency EVAR procedures during the study period; however, the overall in-hospital mortality associated with EVAR remained unchanged, and the length of hospital stay showed a decreasing trend. The total hospital charges for EVAR were lower than the charges for open abdominal aneurysm repair throughout the study period; the difference in charges between the procedures showed a significant increasing trend with time.
