Overview of general surgery medical residency programs and prerequisite program in basic surgical area in Brazil: Historical review and update.

Objective: to describe vacancy regulation process by adding, describing the panorama of the General Surgery Residency Program (PRMCG) and the Basic Surgical Prerequisites Program (PRACB).

Method: descriptive, quali-quantitative, cross sectional study conducted from document analysis from National Commission of Medical Residency (CNRM).

Results: in 2018, after evaluation of the General Surgery Services for adequacy of the number of vacancies (DS), the PRACB was instituted as a modality of access to surgical specialties until definitive change in the time of the formation of the general surgeon for three years, in 2022.

Infrapopliteal Angioplasty of One or More than One Artery for Critical Limb Ischaemia: A Randomised Clinical Trial.

Objective: The aim was to analyse the effect of the treatment of more than one infrapopliteal artery with respect to wound healing and limb salvage.

Methods: Seventy-eight patients were enrolled prospectively for 80 procedures (80 limbs) that were randomly divided into two groups: 40 in the single vessel (SV) group and 40 in the multiple vessel group (MV). All patients had tissue loss.

Safety and efficacy of the EPIC™ nitinol vascular stent system for the treatment of lesions located in the superficial femoral artery: prospective and multicentric trial.

Background: The aim of this study was to evaluate the short and mid-term safety and efficacy of the EPIC™ nitinol vascular stent system for the treatment of lesions located in the superficial femoral artery (SFA).

Methods: From October 2010 to June 2012, 83 subjects were enrolled in a prospective, multicenter, non-randomized study designed to demonstrate that the EPIC nitinol vascular stent system for SFA lesions is non-inferior to the published patency rates found in literature. Inclusion criteria were stenosis or occlusion of the SFA or SFA and proximal popliteal artery, with total length from 4 to 11 cm and amenable for treatment with a single stent, in patients with a score from 2 to 5 on Rutherford classification.

Hybrid procedures for complex thoracic aortic diseases.

Background: Hybrid procedures for the treatment of complex thoracic aortic diseases (CTAD) require the revascularization of one or more supra-aortic arteries, followed by the deployment of one or more aortic endoprosthesis, with lower morbidity and mortality compared to conventional surgery.

Objectives: To evaluate the technique and results of hybrid procedures for CTAD.

Methods: During two years, 12 patients with CTAD underwent hybrid procedures, including aortic arch aneurysms and acute Stanford A and B aortic dissections.
