Alternativa de abordagem endovascular para hematoma em expansão pós-punção arterial: relato de dois casos

Abstract

The increasing number of endovascular procedures performed worldwide made the incidence of iatrogenic complications from arterial punctures more relevant, with rate of these events ranging from 0.5 to 11%. Conventional approaches involving local compression, use of puncture closure devices, are frequently used, but in cases with higher complexity, a surgical approach is usually required. Endovascular techniques are increasingly described as alternatives for surgical repair of these complications due to their efficacy, safety and lower morbidity. In this report, we illustrate the cases of two patients with post-puncture expansive hematomas in which a technique of balloon catheter insufflation for endovascular hemostasis of the arterial hemorrhage points was successfully used. This approach was satisfactory, with resolution of the vascular complication, and avoiding greater morbidity.
