Prospective randomized study on the efficacy of three-dimensional reconstructions of bronchovascular structures on preoperative chest CT scan in patients who are candidates for pulmonary segmentectomy surgery: the PATCHES (Prospective rAndomized sTudy efficaCy of tHree-dimensional rEconstructions Segmentecomy) study protocol.

Introduction: Pulmonary segmentectomy, when combined with hilar and mediastinal lymphadenectomy, is currently considered the gold standard treatment for early-stage lung tumors (NSCLC) smaller than 2 cm in diameter. The preoperative planning for segmentectomies usually includes a contrast-enhanced CT with 2D reconstructions (axial, coronary, and sagittal). Recent technological advances allow 3D (volume rendering) reconstructions of preoperative CT scans, intended to improve the surgeon's understanding of the segmental anatomy.

A Delphi Consensus report from the "Prolonged Air Leak: A Survey" study group on prevention and management of postoperative air leaks after minimally invasive anatomical resections.

Objectives: This study reports the results of an international expert consensus process evaluating the assessment of intraoperative air leaks (IAL) and treatment of postoperative prolonged air leaks (PAL) utilizing a Delphi process, with the aim of helping standardization and improving practice.

Methods: A panel of 45 questions was developed and submitted to an international working group of experts in minimally invasive lung cancer surgery. Modified Delphi methodology was used to review responses, including 3 rounds of voting.

Prognostic interaction between age and sex on outcomes following carotid endarterectomy.

The aim of this study was to assess the prognostic interaction between age and sex on peri-operative and follow-up outcomes following elective carotid endarterectomy (CEA) for asymptomatic and symptomatic carotid stenosis. A retrospective review of all patients admitted to a single vascular unit who underwent elective CEA between January, 2015 and December, 2019 was performed. The primary endpoints of the study were overall survival (from index operation) and cumulative stroke rate at thirty days.

Preliminary Clinical and Radiologic Outcome of Matched Patients with Thoracoabdominal Aortic Aneurysms Treated by Low-Profile vs Standard Profile Branched Aortic Endografts.

Background: Durability of low-profile branched aortic stent-grafts (LPSG) in the treatment of patients with thoracoabdominal aortic aneurysms (TAAA) remains unclear. Objective of this study is to compare the outcomes of LPSG with standard profile branched aortic stent-grafts (SPSG).

Methods: Between January 2016 and January 2020, 225 consecutive patients with TAAA were treated by branched endovascular aortic repair (BEVAR).

Use of Stainless-Steel, Balloon-Expandable Chimney Grafts Is Durable Though Caution Is Required When Lining Angulated Renal Arteries.

Purpose: To analyze the overall performance of flexible nitinol stents used to line chimney grafts (CGs) during chimney endovascular aneurysm repair (chEVAR) of pararenal pathologies.

Materials And Methods: A retrospective review was conducted of all 116 elective patients (mean age 74.3±7.

Endovascular treatment of proximal para-anastomotic aneurysms after previous surgical repair of infrarenal aortic aneurysms by the chimney technique.

Objectives: To evaluate the use of chimney grafts in the treatment of para-anastomotic aneurysms after previous abdominal aortic aneurysms open repair with short neck.

Methods: A retrospective analysis of prospectively collected data of consecutive patients who underwent endovascular repair for proximal aortic para-anastomotic aneurysms following previous open repair for infrarenal abdominal aortic aneurysms was performed. All included patients had a short infrarenal aortic neck (<10 mm) excluding standard endovascular aortic repair.

Treatment of Complex Abdominal Aortic Aneurysms with Parallel Graft-Endovascular Aneurysm Repair. Retrospective Analysis of a Single Center Experience and Midterm Results.

Background: We sought to evaluate the midterm results of parallel-graft-endovascular aneurysm repair (pg-EVAR) for complex aortic anatomy in high-risk candidates for open surgical repair of abdominal aortic aneurism (AAA).

Methods: Clinical and radiographic information on 35 patients treated by pg-EVAR between March 2010 and December 2015 was retrospectively reviewed and analyzed. All patients presented with symptomatic aneurysms and were treated within 3 days of clinical presentation.
