Numerical Analysis of the Mechanical Properties of a Vena Cava Filter

چکیده
When anticoagulants are contraindicated for the venous thromboembolism therapy and thromboembolism recurs, a vena cava filter is inserted percutaneously into a major vein in order to prevent blood clots from entering the lungs (Ando & Kuribayashi, 2000; Streiff, 2000) (Fig. 1). The inferior vena cava filter is a mesh structure designed to capture blood clots while not impeding blood flow. This filter is inserted using an introducer catheter from either the femoral or jugular vein and is fixed by a hook attached to the tip of a wire. Several filters have been designed to lyse captured clots.

Superior Vena Cava Syndrome due to Thrombosis: A Rare Paraneoplastic Presentation of Bronchogenic Carcinoma
Superior vena cava (SVC) syndrome is not an uncommon occurrence in patients with malignancy and it is often described as a medical emergency. In majority of the cases, SVC syndrome occurs due to mechanical obstruction of the SVC by extraluminal compression with primary intrathoracic malignancies. However, intraluminal obstruction due to thrombosis can also produce symptoms and signs of SVC synd...
متن کاملThe use of retrievable inferior vena cava filters in orthopaedic patients.
This study was undertaken to evaluate the safety and efficacy of retrievable inferior vena cava filters in high-risk orthopaedic patients. A total of 58 patients had a retrievable inferior vena cava filter placed as an adjunct to chemical and mechanical prophylaxis, most commonly for a history of previous deep-vein thrombosis or pulmonary embolism, polytrauma, or expected prolonged immobilisati...
متن کاملThe efficacy of inferior vena cava diameters and the jugular vein in assessing fluid resuscitation
Objective: Fluid resuscitation is necessary in almost all critical patients. The central venous pressure (CVP) is a well-established method of assessing resuscitation. Recently, there have been attempts to investigate less invasive methods like the diameters of inferior vena cava (IVC) or the jugular vein. We aimed to investigate this method in our research.Methods: Seventy eight critical...

Primary neuroendocrine carcinoma (NEC) of the mediastinum is a rare type of carcinoma. According to the literature, only five cases of this condition have been reported so far. In this paper, we present a rare case of mediastinal NEC of unknown primary site. The patient was a 34-year-old man with mediastinal NEC, who presented with chronic dry cough and a right-sided mediastinal mass one year p...
