Postoperative Anticoagulation in Vascular Reconstructions Associated with Malignancies.

Background: The invasion of truncal arteries and veins by malignant neoplasms is rare and the surgical treatment remains a challenge. Several techniques can be used to re-establish blood flow in a resected vessel and choice of the ideal vascular substitute frequently arises a debate. Comparative studies between prosthetic and autologous grafts disclose conflicting patency results.

An alternative approach to treatment of inferior vena cava filter perforation.

We report a case of inferior vena cava filter perforation immediately after filter implantation, recognized intraoperatively in a patient undergoing laparotomy for resection of locally advanced ovarian cancer. We describe an alternative approach with strut resection, less invasive than filter removal, enabling the device to be maintained and bleeding to be controlled.

Inferior Vena Cava Filter in Cancer Patients: On Whom Should We Be Placing Them?

Background: Standard treatment for venous thromboembolism is anticoagulation; vena cava filter placement is an alternative in special situations. We aimed to evaluate the outcomes in patients with cancer undergoing filter placement in a cancer center during a 10-year period and assess which preoperatory variables were associated with poorer survival.

Methods: Retrospective unicenter analysis during a 10-year period was carried out in patients with cancer who had undergone placement of vena cava filter.

Twenty years of experience in vascular reconstructions associated with resection of malignant neoplasms in a single cancer center.

Objective: Vascular invasion is no longer considered to be an absolute contraindication to tumor removal, and complex reconstructions are part of the daily activity of vascular surgeons in specialized cancer centers. Our aim was to report a single-center experience of complex vascular reconstructions involving en bloc resection of tumors and patients' long-term survival and graft patency outcomes. To the best of our knowledge, this is the largest report of vascular reconstructions published to date, with the longest follow-up.

Comparison between Saline Solution Containing Heparin versus Saline Solution in the Lock of Totally Implantable Catheters.

Background: There are only 3 studies comparing the efficacy of 2 different types of lock used in totally implantable catheters regarding occlusion or reflux dysfunction. The present study contains the largest published casuistry (862 patients) and is the only one that analyzes 3 parameters: occlusion, reflux dysfunction, and flow dysfunction.

Methods: This was a retrospective study of patients operated at a large oncology center and followed up in the outpatient clinic between 2007 and 2015.

Brachial insertion of fully implantable venous catheters for chemotherapy: complications and quality of life assessment in 35 patients.

Objective: To prospectively evaluate the perioperative safety, early complications and satisfaction of patients who underwent the implantation of central catheters peripherally inserted via basilic vein.

Methods: Thirty-five consecutive patients with active oncologic disease requiring chemotherapy were prospectively followed up after undergoing peripheral implantation of indwelling venous catheters, between November 2013 and June 2014. The procedures were performed in the operating room by the same team of three vascular surgeons.

Oral Rivaroxaban for the Treatment of Symptomatic Venous Thromboembolism in 400 Patients With Active Cancer: A Single-Center Experience.

Purpose: To study the safety and efficacy of rivaroxaban-a direct oral anticoagulant-use in patients with active cancer and venous thromboembolism (VTE).

Patients And Methods: Retrospective cohort study of 400 patients with active cancer and associated VTE, defined as deep venous thrombosis and/or pulmonary embolism. This single-center study was carried out from January 2012 to June 2015.

Treatment of Abdominal Aortic Aneurysms in Cancer Patients.

Background: The aim of this study was to analyze the outcomes of oncologic patients with associated aneurysm of the abdominal aorta (AAA), treated at a specialized cancer (Ca) hospital more than a 10-year period.

Methods: This was a retrospective study, and the data were obtained from our institution's prospective database. Between September 2003 and 2013, a total of 36 consecutive patients with AAA in association with Ca underwent surgical repair.
