Review Case Reports
Recurrent embolism caused by floating thrombus in the thoracic aorta.
A case of embolic recurrent episodes resulting in acute lower-limb ischemia from an unusual source is reported. This occurred in a patient on steroids for rheumatoid arthritis. Femoropopliteal thromboembolectomy successfully restored arterial flow. ⋯ The thrombus was identified by transesophageal echocardiography and was successfully removed by aortic thromboendarterectomy. We emphasize the importance of transesophageal echocardiography as a reliable method for the diagnosis of thoracic aorta diseases and for identification of aortic thrombi. An aggressive surgical approach is recommended in the low-risk patient to prevent further embolic episodes.

Comparative Study
Postoperative epidural analgesia following abdominal aortic surgery: do the benefits justify the costs?
This study was undertaken to compare postoperative epidural analgesia (PEA) with patient-controlled analgesia (PCA) regarding complications, particularly pulmonary, death, intensive care unit and hospital stay, and hospital and physician charges. The elective consecutive infrarenal abdominal aortic procedures performed by two vascular surgeons over a 1 year period were retrospectively analyzed. Although nonrandomized, of the 80 patients reviewed, 40 received PEA and 40 received PCA. ⋯ Average charge (hospital and physician) per patient for PEA was $2489.00 compared with $443.00 for patients receiving PCA (no physician charges generated for PCA). The results do not support the routine use of PEA following abdominal aortic operations. Savings are more than $2000.00 per patient for PCA compared with PEA.

During 1989, 28 centers of the Association for Academic Research in Vascular Surgery (AURC) reported all cases involving patients with infrarenal abdominal aortic aneurysm (AAA) who reached the operating room alive. In a total series of 1107 procedures, 834 were performed electively. During 1993 and 1994, an effort was made to contact and, if possible re-examine the 794 (95.2%) patients who survived these elective procedures in order to establish survival curves, determine the causes of late death, and ascertain the predictive value for long-term survival of 628 perioperative variables recorded in 1989. ⋯ Life expectancy in patients that undergo successful AAA repair is lower than in the general population. Although death is often unrelated to AAA or the repair procedure, the incidence of morbidity due to cardiovascular disease is higher than in a control population matched for age and sex. These findings suggest that better management of concurrent cardiovascular disease during the perioperative period and long-term follow-up holds the key to improving life expectancy in patients undergoing AAA repair.

Paradoxic embolus is uncommon. Definite diagnosis requires demonstration of thrombus astride a patent foramen ovale (PFO) in a patient presenting cerebral or peripheral arterial embolism. With current echocardiography techniques, it is now possible to identify subjects with a PFO at risk for paradoxal embolism, however, the possibility of screening rekindles debate on prophylaxis and treatment. In the present report, we describe a case involving a woman who presented acute ischemia of the lower extremities with all the pathophysiologic features of paradoxical arterial embolism.
