A survey of patients lost to follow-up after inferior vena cava filter placement.
The objective of this study was to determine the demographics and subjective rationale for failure to present for retrieval of patients who had an inferior vena cava (IVC) filter placed. ⋯ Our study documented a disappointingly low rate of filter retrieval. Patients with IVC filters who failed to present for retrieval were more likely to be older and frequently did not understand the complications of leaving a filter in place and the need to have the filter retrieved. Patient education should be increased to better capture patients with IVC filters and to improve retrieval rates, but our study showed that a significant percentage of patients do not have filters retrieved because of comorbidities or they do not want another procedure.

Multicenter Study Comparative StudyIncidence of major adverse cardiovascular events among patients with provoked and unprovoked venous thromboembolism: Findings from the Registro Informatizado de Enfermedad Tromboembólica Registry.
Overlap exists between the risk factors for coronary artery disease and venous thromboembolism (VTE). However, a paucity of data is available on the incidence of major acute cardiovascular events (MACE) and major adverse limb events (MALE) among patients presenting with VTE. Moreover, it is unknown whether the rate of cardiovascular outcomes differs among patients with unprovoked vs provoked VTE. ⋯ Among patients with VTE, provoked cases, specifically those with cancer-associated VTE, have an increased risk of major arterial events.

Predicting the Safety and Effectiveness of Inferior Vena Cava Filters Study: Design of a unique safety and effectiveness study of inferior vena cava filters in clinical practice.
Death from venous thromboembolism remains a significant cause of death worldwide. Although anticoagulation is the cornerstone of treatment in patients at risk for venous thromboembolism, inferior vena cava (IVC) filter use has increased exponentially over the last decade driven predominantly by the prophylactic use in patients at risk for venous thromboembolism despite limited evidence supporting this practice. The Predicting the Safety and Effectiveness of Inferior Vena Cava Filters (PRESERVE) Study is being implemented by the Society for Vascular Surgery, Society of Interventional Radiology, U.S. Food and Drug Administration, and several IVC filter manufactures to better understand the safety, effectiveness, and current patterns of real-world use of IVC filters. ⋯ The PRESERVE Study represents the largest prospective study ever undertaken to investigate real-world outcomes with contemporary use of IVC filters. The investigators await results with the hope that it can improve patient care.

Multicenter StudyClosed incisional negative pressure therapy may reduce surgical site infection rate following endophlebectomy with complementary polytetrafluoroethylene arteriovenous fistula of the common femoral vein.
Surgical desobliteration or endophlebectomy of the common femoral vein during deep venous recanalization with complementary polytetrafluoroethylene (PTFE) arteriovenous fistula (AVF), may lead to higher rates of surgical site infection (SSI). It has been reported that closed incisional negative pressure wound therapy (cINPT) may decrease SSI rates after different surgical procedures. The aim of this study was to determine the potential effect of cINPT on the SSI rate of femoral endophlebectomy with a complimentary PTFE AVF. ⋯ Endophlebectomy with complementary PTFE AVF of the femoral vein is related to an increased rate of lymphatic leakage and SSI. Lymphatic fistula and the duration of surgery could be assessed as relevant influencing factors of SSI. Application of cINPT in this surgical setting may reduce the SSI rate. Despite this potential improvement, SSI rates still limit the clinical success of a deep venous recanalization.

Comparative Study Observational StudyUtilization of the Caprini score in conjunction with thrombodynamic testing reduces the number of unpredicted postoperative venous thromboembolism events in patients with colorectal cancer.
The thrombodynamic test (TD) is a novel global test of hemostasis that allows to study the spatial-temporal characteristics of a clot formation in real time under conditions close to natural ones and demonstrates high sensitivity to detect the state of hypercoagulation. The main paraments of the test are the velocity of clot growth, clot's size, and clot density. The objective of this study was to compare the classic Caprini 2005 score and its modified version in association with the results of TD. The goal is to predict postoperative venous thromboembolism (VTE) in surgical patients undergoing surgery for colorectal cancer. ⋯ Integrating TD parameters into the Caprini score increases the ability to predict postoperative VTE.
