Inferior vena cava (IVC) filters are medical devices designed to provide a mechanical barrier to the passage of emboli from the deep veins of the legs to the heart and lungs. Despite decades of development and clinical use, IVC filters still fail to prevent the passage of all hazardous emboli. The objective of this study is to (1) develop a resolved two-way computational model of embolus transport, (2) provide verification and validation evidence for the model, and (3) demonstrate the ability of the model to predict the embolus-trapping efficiency of an IVC filter...

We present a case of intramural duodenal haematoma caused by inferior vena caval (IVC) filter strut perforation requiring innovative open and endovascular retrieval. A 32-year-old woman presents in shock with dull epigastric pain and non-bilious vomiting. She had previously had an IVC filter for deep venous thrombosis and pulmonary embolism. Computed tomography demonstrated strut perforation into the second part of the duodenum, causing intramural haematoma and duodenal obstruction. Laparotomy facilitated evacuation of the duodenal haematoma, while the IVC filter was retrieved by endovascular means...

The use of inferior vena cava filters to prevent pulmonary embolism is increasing mainly because of indications that appear to be unclearly codified and recommended. The evidence supporting this approach is often heterogeneous, and mainly based on observational studies and consensus opinions, while the insertion of an IVC filter exposes patients to the risk of complications and increases health care costs. Thus, several proposed indications for an IVC filter placement remain controversial. We attempt to review the proof on the efficacy and safety of IVC filters in several "special" clinical settings, and assess the robustness of the available evidence for any specific indication to place an IVC filter...

Inferior vena cava (IVC) filter is a medical device placed in patients with proven pulmonary embolism or those with risk of embolization. Although many IVC filters are designed for removal after patient recovery, in many instances they are never retrieved. We present a case of a 22-year-old woman who underwent placement of an IVC filter as a prophylactic measure following a C-6 spinal injury that rendered her a quadriplegic. A tyne from the filter later fractured and embolized to the right ventricle, leading to perforation and subsequent large symptomatic pericardial effusion...

Published reports indicate low retrieval rates for retrievable inferior vena cava (IVC) filters. We performed a historic-controlled study of a 5-year intervention (March 2007 to February 2012) to improve IVC filter retrieval at a university medical center serving a rural area. All adults with a retrievable filter placed were included, except those with a life expectancy <6 months. The intervention included initial verbal counseling and printed educational materials, correspondence after discharge, and a hematology consultation...

BACKGROUND: Many patients are subjected to the potential risks and morbidity associated with an indwelling IVC filter when standard methods fail to remove the filter. We evaluated the safety and effectiveness of the excimer laser-sheath technique for removing embedded IVC filters. METHODS: Over a 5-year period, 251 consecutive patients undergoing laser-assisted filter retrieval were prospectively enrolled. There were 103 men and 148 women (mean:46 years, range:15-82)...

OBJECTIVE: The incidence of thrombus was investigated within retrievable filters placed in trauma patients with confirmed DVT at the time of retrieval and the optimal treatment for this clinical scenario was assessed. A technique called "filter retrieval with manual negative pressure aspiration thrombectomy" for management of filter thrombus was introduced and assessed. METHODS: The retrievable filters referred for retrieval between January 2008 and December 2015 were retrospectively reviewed to determine the incidence of filter thrombus on a pre-retrieval cavogram...

Importance: Trauma patients admitted to the hospital are at increased risk of bleeding and thrombosis. The use of inferior vena cava (IVC) filters in this population has been increasing, despite a lack of high-quality evidence to demonstrate their efficacy. Objective: To determine if IVC filter insertion in trauma patients affects overall mortality. Design, Setting, and Participants: This retrospective cohort study used stratified 3:1 propensity matching to select a control population similar to patients who underwent IVC filter insertion at Boston Medical Center (a level I trauma center at Boston University School of Medicine) between August 1, 2003, and December 31, 2012...

We present a rare late complication after inferior vena cava filter (IVC) placement. A 52-year-old woman with an IVC presented with sudden onset of chest pain. Cardiac catheterisation and echocardiography revealed an embolised IVC filter strut penetrating the right ventricle. Endovascular retrieval was considered but deemed unsafe due to proximity to the right coronary artery and concern for migration to pulmonary circulation. Urgent removal of the strut was performed via sternotomy. The postoperative course was uneventful...

BACKGROUND: Inferior vena cava (IVC) thrombosis may occur in patients with iliofemoral deep venous thrombosis (DVT), and its impact on thrombolysis outcomes is poorly defined. This study compared outcomes of patients undergoing thrombolysis for acute iliofemoral DVT with and without IVC involvement. METHODS: Patients who underwent thrombolysis for iliofemoral DVT between May 2007 and March 2014 were identified from a prospectively maintained database and divided into two groups: those with IVC involvement and those without...

Venous thromboembolic disease is a major cause of morbidity in cancer patients. The Perspective database was used to identify patients with solid tumors and a diagnosis of VTE from 2006 to 2012. We examined use of IVC filters, thrombolysis, and thrombectomy. Among 32,545 patients, 23.1% received an IVC filter, 1.9% thrombolytic therapy, and 0.4% underwent thrombectomy. Use of IVC filters decreased between 2006 and 2012 (23.4% to 21.2%, p = 0.012). Older patients, uninsured patients, Hispanics, and those with more comorbidities were more likely to undergo filter placement while patients at rural hospitals were less likely to receive an IVC filter (p < 0...

A 43-year-old woman presented with severe anaemia secondary to menorrhagia. Pelvic ultrasound showed a large intramural posterior fundal fibroid. Hysteroscopy showed the fibroid distorting the endometrial cavity, precluding Mirena® device insertion. As she was initially hesitant to have a hysterectomy, medical management with the oral contraceptive pill (OCP) and tranexamic acid was instituted, with good effect. Months later, after a long road trip, she presented with left leg swelling, and a Doppler ultrasound confirmed an extensive deep vein thrombosis (DVT)...

BACKGROUND Intraoperative pulmonary embolism (PE) is a rare life-threatening complication in patients undergoing surgical intervention. Generally, cancer patients have a higher risk for developing this complication. Unfortunately, there is no standard procedure for its management. CASE REPORT We report the case of a 39-year-old woman with high-grade glioma in the right frontal lobe who was admitted to the surgical theater for craniotomy and excision of the tumor. During the general anesthesia procedure and just before inserting the central venous line, her end-tidal CO2 and O2 saturation dropped sharply...
