OBJECTIVE: This study compared the efficacy and complication rates of inferior vena cava (IVC) filters for calf vein thrombosis (CVT) vs conservative treatment with or without anticoagulation. METHODS: Vascular laboratory studies of patients who had an isolated CVT (anterior and posterior tibialis, peroneal, soleal, and gastrocnemius veins) from April 2009 to January 2014 were retrospectively analyzed from a single institution. Of 647 patients with isolated CVT, 285 (44%) received an IVC filter, and 362 (56%) received medical treatment alone (38...

Inferior vena cava (IVC) filters have been used for nearly half a century to prevent pulmonary embolism in at-risk patients. However, complications with IVC filters remain common. In this study, we investigate the importance of considering the hemorheological and morphological effects on IVC hemodynamics by simulating Newtonian and non-Newtonian blood flow in three IVC models with varying levels of geometric idealization. Partial occlusion by an IVC filter and a thrombus is also considered. More than 99% of the infrarenal IVC volume is found to contain flow in the nonlinear region of the shear rate-viscosity curve for blood (less than 100 s(-1)) in the unoccluded IVCs...

BACKGROUND: Preoperative "prophylactic" placement of inferior vena cava (IVC) filters in morbidly obese patients (e.g., body mass index [BMI] >40 or BMI over 35 with hypertension/diabetes) undergoing multilevel decompressive lumbar laminectomies may reduce the risk of postoperative pulmonary embolism (PE), and death. METHODS: Two patients, ages 69 and 68, with morbid obesity (BMI's of 40.4 and 37.5 both with hypertension and diabetes), received prophylactic IVC filters prior to L1-S1 laminectomies...

Background Pulmonary embolus (PE) remains a leading etiology of maternal mortality in the developed world. Increasing utilization of retrievable inferior vena cava (IVC) filter placement currently includes pregnant patients. Case A 22-year-old woman at 27 weeks' gestation was diagnosed with Stage IV high-grade malignant B cell lymphoma following pathologic femur fracture. Significant risk factors for PE led to placement of primary prophylaxis IVC filter before cesarean delivery, open reduction and internal fixation of the fractured femur, and chemotherapy...

OBJECTIVE: Trauma patients are at high risk for life-threatening venous thromboembolic (VTE) events. We examined the relationship between prophylactic inferior vena cava (IVC) filter use, mortality, and VTE. SUMMARY BACKGROUND DATA: The prevalence of prophylactic placement of IVC filters has increased among trauma patients. However, there exists little data on the overall efficacy of prophylactic IVC filters with regard to outcomes. METHODS: Trauma quality collaborative data from 2010 to 2014 were analyzed...

Postoperative acute pulmonary embolism after pulmonary resections is highly fatal complication. Many literatures have documented cancer to be the highest risk factor for acute pulmonary embolism after pulmonary resections. Early diagnosis of acute pulmonary embolism is highly recommended and computed tomographic pulmonary angiography is the gold standard in diagnosis of acute pulmonary embolism. Anticoagulants and thrombolytic therapy have shown a great success in treatment of acute pulmonary embolism. Surgical therapies (embolectomy and inferior vena cava filter replacement) proved to be lifesaving but many literatures favored medical therapy as the first choice...

Filter technology seems relatively stable, although absorbable devices are an area of investigational interest. The indications for filter placement remain controversial, with wide variations in adherence to guidelines, and relatively poor quality of data about the specific prophylactic indications of trauma or bariatric surgery. The outcomes of filters are not well-defined despite widespread clinical use, and good data remains difficult to obtain. Several larger database and institutional retrospective studies support the notions that while filters prevent pulmonary embolism, they may be associated with venous thrombotic complications...

We present a case report of simultaneous pulmonary emboli and paradoxical embolism to the cerebellum causing a stroke and severe ischemia to the left leg. This patient had risk factors for thromboembolic events that included autoimmune disease, cancer, and recent pelvic surgery. The presence of a perforate foramen ovale was suspected on his initial presentation and confirmed with echocardiography. For acute leg ischemia, this patient underwent emergent left common femoral embolectomy. The potential benefit of immediate anticoagulation had to be weighed against the risk of hemorrhagic transformation of his cerebellar stroke with possible compression of the fourth ventricle...

The risk of venous thromboembolism (VTE) is high for patients with brain tumors (11-20 %). Glioblastoma (GBM) patients, in particular, have the highest risk of VTE (24-30 %). The Khorana scale is the most commonly used clinical scale to evaluate the risk of VTE in cancer patients but its efficacy in patients with GBM remains unclear. The aim of this study is to estimate the frequency of VTE in GBM patients and identify potential risk factors for the development of VTE during adjuvant chemotherapy. Furthermore, we intend to examine whether the Khorana scale accurately predicts the risk of VTE in GBM patients...

BACKGROUND: Venous thromboembolism (VTE) is a frequent complication of patients who experienced major trauma. Prevention of VTE is usually by thrombophylaxis and or by the use of a retrievable filter. Lately, the use of a retrievable filter in trauma patients has increased despite evidence cautioning against its use. AIMS: To evaluate complications related to a single type of filter prophylactically used in a tertiary trauma center and search for risk factors that may preclude filter retrieval METHODS: 142 patients aged 16 through 60 who experienced a major trauma and were treated with a prophylactic IVC filter of type optease were evaluated...

BACKGROUND: Trauma patients are known to be at increased risk for venous thromboembolism (VTE); this risk may change over time following injury. Determining the period in which patients are at increased risk of developing VTE may have an impact on prophylaxis, cost, and quality of care. METHODS: The California Office of Statewide Health Planning and Development hospital discharge database was searched between 1995 and 2010 for patients admitted with traumatic pelvic fractures, vertebral fractures, and spinal cord injuries...

OBJECTIVE: The use of inferior vena cava (IVC) filters for prevention of venous thromboembolism (VTE) in bariatric surgery is a contentious issue. We aim to review the evidence for the use of IVC filters in bariatric surgical patients, describe trends in practice, and discuss challenges in developing evidence-based guidelines. BACKGROUND: The incidence of VTE in modern bariatric procedures with traditional methods of thromboprophylaxis, such as sequential calf compression devices and perioperative low molecular weight heparin, is approximately 2%...
