ABSTRACT
AIM: To compare the acute effects of two resistance exercise sessions with different partial blood flow restrictions (BFR) on hemodynamic parameters and cardiac autonomic modulation in older women with metabolic syndrome. METHODS: Thirty-nine older women (64.4 ± 4.5 years) were allocated into three groups: BFR0 = resistance exercise (20%, 1 maximum repetition [MR]) + 0% BFR; BFR60 = 20% 1 MR resistance exercise + 60% BFR; and BFR80 = 20% 1MR resistance exercise + 80% BFR. RESULTS: A reduction of 14 mmHg (BFR60 group) and 13 mmHg (BRF80 group) was observed 48 hr after the first exercise session, while vagal modulation was increased in the BRF60 group after 24 and 48 hr. CONCLUSION: A low-intensity resistance exercise session with 60% and 80% of BFR resulted in blood pressure (systolic, diastolic, and mean) reduction and positive changes on heart rate variability after 24 h of a RE session.

The occurrence of vascular trauma due to a range of causes has increased considerably. In this setting, endovascular repair has arisen as a new and less invasive approach. We report the case of three patients with lesions of below-knee vessels that were treated by endovascular procedures.
A ocorrência de trauma vascular decorrente de diversas causas aumentou consideravelmente. Nesse contexto, o tratamento endovascular surge como um método novo e menos invasivo. Relatamos o caso de três pacientes com lesões abaixo do joelho que foram tratadas por procedimentos endovasculares.
