ABSTRACT
Abstract Introduction: Endovascular repair (EVAR) of abdominal aortic aneurysm has become the standard of care due to a lower 30-day mortality, a lower morbidity, shorter hospital stay and a quicker recovery. The role of open repair (OR) and to whom this type of operation should be offered is subject to discussion. Objective: To present a single center experience on the repair of abdominal aortic aneurysm, comparing the results of open and endovascular repairs. Methods: Retrospective cross-sectional observational study including 286 patients submitted to OR and 91 patients submitted to EVAR. The mean follow-up for the OR group was 66 months and for the EVAR group was 39 months. Results: The overall mortality was 11.89% for OR and 7.69% for EVAR (P=0.263), EVAR presented a death relative risk of 0.647. It was also found a lower intraoperative bleeding for EVAR (OR=1417.48±1180.42 mL versusEVAR=597.80±488.81 mL, P<0.0002) and a shorter operative time for endovascular repair (OR=4.40±1.08 hoursversus EVAR=3.58±1.26 hours,P<0.003). The postoperative complications presented no statistical difference between groups (OR=29.03% versusEVAR=25.27%, P=0.35). Conclusion: EVAR presents a better short term outcome than OR in all classes of physiologic risk. In order to train future vascular surgeons on OR, only young and healthy patients, who carry a very low risk of adverse events, should be selected, aiming at the long term durability of the procedure.

A case of acquired megacolon in a 62-year-old man with acute abdomen due to sigmoid volvulus is reported. The case was associated with the use of psychiatric medications. The aim in this report was to emphasize the differential diagnosis with Chagas megacolon. Anatomopathological examination did not show any evidence of denervation, ganglionitis and/or myositis, and the serological test for Chagas disease was negative.
Relata-se caso de megacólon adquirido, associado ao uso de medicamentos psiquiátricos, em homem de 62 anos, com abdome agudo por volvo de sigmóide, com o objetivo de destacar o diagnóstico diferencial de megacólon chagásico. O exame anátomo-patológico não evidenciou denervação, ganglionite e/ou miosite e a sorologia para doença de Chagas foi negativa.
