Asymptomatic Duodenal Perforation from an Inferior Vena Cava Filter

Conservative Management of Duodenal Penetration by Inferior Vena Cava Filter: Case Report and Review

Duodenal penetration is a late complication associated with the placement of inferior vena cava (IVC) filters. In this case report, we are presenting a case of asymptomatic duodenal penetration by IVC filter that was managed conservatively.

Gastro-caval fistula after distal esophageal resection: a case report and review of the literature

Peptic ulceration with fistula formation into the inferior vena cava is rare, difficult to diagnose, and associated with high mortality. The nonspecific signs and symptoms make diagnosis challenging, delaying optimal treatment. Although there have been reports on duodeno-caval fistulas, gastric communication with the inferior vena cava is very rare. We report the second case of a fatal gastro-caval fistula and performed a review of the literature on entero-caval fistulas to emphasize the importance of early suspicion and to understand the most common presentation, as well as the best diagnostic and treatment modalities of this rare pathology.

Surgical removal of an inferior vena cava filter with duodenal penetration

Complications due to long-term implantation of inferior vena cava (IVC) filters have increased. Among these, IVC wall penetration by struts can lead to penetration of adjacent structures, which can be fatal to the patient. Herein, we report a case of a 63-year-old woman who underwent surgical removal of an IVC filter with duodenal penetration. Oesophagogastroduodenoscopy findings revealed a strut in the duodenal second portion. The IVC filter was inserted 19 months ago but had not been retrieved. On admission, computed tomography showed malposition of the IVC filter with penetration of duodenum by an anterior strut. Therefore, we performed surgical removal of the IVC filter. After surgery, her postoperative course was uneventful.

Retrievable IVC Filters: Comprehensive Review of Device-related Complications and Advanced Retrieval Techniques

Use of retrievable inferior vena cava filters (RIVCFs) has grown exponentially since their introduction into clinical practice, but many of these devices are not retrieved. Some are not retrieved due to poor clinical follow-up, but other devices remain in situ for extended periods because they present significant technical challenges during retrieval. Because of these and other factors, many of these devices were thus left in place permanently. However, recent data have placed a renewed emphasis on device retrieval due to increased risk of RIVCF-related complications, which are positively correlated with filter dwell time. Development of advanced filter retrieval techniques has had a significant impact on the removal of embedded RIVCFs, permitting retrieval of the majority of devices. The purpose of this article is to present an imaging and data review of the dominant device-related factors that complicate RIVCF retrieval and to describe the relevant advanced retrieval techniques to manage these factors. RIVCF imaging is frequently encountered in daily clinical practice via various imaging modalities. Therefore, diagnostic radiologists can play a vital role in identifying filter-related issues. Familiarity with the context for managing these issues in the interventional suite is essential for improving triage and care of patients with RIVCFs. ^© RSNA, 2017.
