Surgical Treatment for Thrombus Straddling a Patent Foramen Ovale

Abstract We present a case of a 41-year-old female with deep vein thrombosis after abdominal surgery. The patient quickly developed severe pulmonary embolism and stroke representative of paradoxical embolism. Echocardiography showed a thrombus straddling a patent foramen ovale, which was confirmed intraoperatively. An accurate diagnosis and rapid treatment decisions are crucial for preventing patient deterioration in the form of new pulmonary embolisms or stroke

Efeito sinérgico entre a dexmedetomidina e a ropivacaína 0,75% na anestesia peridural

BACKGROUND. This study aimed to evaluate clinical characteristics of epidural anesthesia performed with 0.75% ropivacaine associated with dexmedetomidine. METHODS. Forty patients scheduled for hernia repair or varicose vein surgeries under epidural anesthesia participated in this study. They were assigned to: Control Group (n = 20), 0.75% ropivacaine, 20 ml (150 mg); and Dexmedetomidine Group (n = 20), 0.75% ropivacaine, 20 ml (150 mg), plus dexmedetomidine, 1 μg.kg -1. The following variables were studied: total analgesic block onset time, upper level of analgesia, analgesic and motor block duration time, intensity of motor block, state of consciousness, hemodynamics, postoperative analgesia and incidence of side-effects. RESULTS. Epidural dexmedetomidine did not affect onset time or upper level of anesthesia (p > 0.05) however it prolonged sensory and motor block duration time (p 0.05). Occurrence of side-effects (shivering, vomiting and SpO 2 0.05). CONCLUSION. There is clear synergism between epidural dexmedetomidine and ropivacaine, further this drug association does not bring about additional morbidity
