Effect of Obesity and Bariatric Surgery on Saphenous Veins.

Purpose: Obesity is a risk factor for chronic venous disease (CVD) of the lower limbs (LL), affecting venous anatomy and physiology. Weight loss after bariatric surgery (BS) can reduce intra-abdominal pressure, improve mobility, and ultimately improve venous hemodynamics and CVD-related symptoms. There are no studies in the literature that adequately assess the effect of the obesity and BS on the LL veins, especially the saphenous veins (SV).

Bacterial cellulose biopolymer film and gel dressing for the treatment of ischemic wounds after lower limb revascularization.

Objective: to evaluate the use of a bacterial cellulose biopolymer film and gel dressing in the treatment of patients with ischemic wounds submitted to lower limb revascularization.

Methods: we conducted a randomized clinical trial in the Angiology and Vascular Surgery outpatient clinic of the Clinics Hospital of the Federal University of Pernambuco, between January 2017 and December 2018. We followed 24 patients after lower limb revascularization, divided into two groups: Experimental, treated with bacterial cellulose biopolymer film and gel, and Control, treated with essential fatty acids.
