The insertion of inferior vena cava (IVC) filters results in device migration at rates that exceed 50% in some studies, although the clinical significance of migration remains in question. These filters can also erode or penetrate the IVC wall, injuring adjacent retroperitoneal and abdominal structures. The risk of erosion or perforation is estimated to be as much as 25%, although clinical symptoms are observed far less frequently in patients with these complications. We describe the presentation, evaluation, and treatment of a patient with an IVC strut protruding into the duodenum. This case report discusses complications, presenting symptoms, and treatment of patients with IVC filters complications.

The purpose of this article is to overview the clinical significance of left supraclavicular adenopathy and review the etiology of inferior vena cava (IVC) thrombosis, starting from a presentation of a rare case of renal cell carcinoma (RCCs) with Xp11.2 translocation involving TFE3 gene fusion. This article also aims to review the literature to understand the characteristics of this rare type of renal tumor.

Background: This study aimed to assess the accuracy of tricuspid spectral Doppler (E/A) and tissue Doppler parameters (E/E') to diagnose right ventricular diastolic dysfunction (RVDD) in comparison to American Society of Echocardiography (ASE criteria) in pediatric tetralogy of Fallot (TOF) patients after surgical repair.
Methods: This prospective, observational study was done at a tertiary care hospital involving 40 pediatric TOF patients aged less than 2 years who underwent complete intracardiac repair with cardiopulmonary bypass (CPB). Echocardiographic observations were made using a pediatric transesophageal echocardiography probe after surgical repair in the post-CPB period.
Device closure of an atrial septal defect from the upper caval vein: simplified technique.

Interruption of the inferior caval vein complicates device closure of atrial septal defects. We present a case where a simplified technique was used: from right jugular access the delivery system was directly engaged into the left atrium, where the entire septal occluder was deployed. Both discs were aligned with the interatrial septum, after which the right disc was recaptured and re-deployed in the right atrium under tension.

Background And Purpose: Symptoms indistinguishable from behavioral-variant frontotemporal dementia (bvFTD) can develop in patients with spontaneous intracranial hypotension associated with severe brain sagging. An underlying spinal CSF leak can be identified in only a minority of these patients and the success rate of nondirected treatments, such as epidural blood patching and dural reduction surgery, is low. The disability associated with bvFTD sagging brain syndrome is high and, because of the importance of the venous system in the pathophysiology of CSF leaks in general, we have investigated the systemic venous circulation in those patients with recalcitrant symptoms.

Wilms' tumor (WT), also known as nephroblastoma, is a malignant embryonal kidney tumor composed of embryonic cells and is the most prevalent tumor among children, but isolated cases occur infrequently in the adult population. Adult WT is defined according to the criteria of Kilton, Matthews, and Cohen, which comprise age above 15 years and histological patterns characteristic of WT. We report a case of an adult WT with venous thrombus on an incomplete duplex collecting system.
