Symptomatic duodenal perforation by a Bird's Nest vena cava filter.

J Vasc Surg Cases Innov Tech 2021 Mar 1;7(1):104-107. Epub 2020 Dec 1.

Division of Vascular and Endovascular Surgery, Department of Surgery, Perelman School of Medicine, University of Pennsylvania, Philadelphia, Pa.

This case describes a patient with a permanent Bird's Nest inferior vena cava filter in the setting of spinal cord injury and paraplegia who presented with epigastric pain resulting from duodenal perforation of his filter. After confirming that the patient was stable hemodynamically with normal laboratory values, he underwent open exploration with trimming of the extraluminal struts and wires, leaving the intact filter in place, with resolution of his pain. Although percutaneous removal of inferior vena cava filters is preferred for retrievable filters, this case demonstrates the safety and efficacy of open surgical management for permanent filters, not designed for retrieval.

Structured team-oriented program to follow patients after vena cava filter placement: a step forward in improving quality for filter retrieval.

Sci Rep 2021 Feb 10;11(1):3526. Epub 2021 Feb 10.

Cardiothoracic and Vascular Division, Department of Diagnostic and Interventional Radiology, Lausanne University Hospital and University of Lausanne, Rue du Bugnon 46, 1011, Lausanne, Switzerland.

To reduce inferior vena cava filter (IVCF) related complications, retrieval is recommended whenever possible. Nevertheless, IVCF retrieval rates remain lower than expected, likely due to insufficient follow-up after placement. We evaluated the value of a structured program designed to follow patients by the interventional radiology team up to 5 months after IVCF placement. Read More

Inferior Vena Cava Filter Placement Through a Venovenous Extracorporeal Membrane Oxygenation Circuit.

Ann Thorac Surg 2021 Jan 30. Epub 2021 Jan 30.

Division of Cardiac Surgery, University of Maryland School of Medicine, Baltimore, MD, USA. Electronic address:

We present a novel technique for performing endovascular procedures by obtaining vascular access directly through a venovenous extracorporeal membrane oxygenation (VV ECMO) circuit. This technique is demonstrated in a lung transplant recipient, supported on VV ECMO, whose course was complicated by an extensive right femoral vein and inferior vena cava (IVC) deep vein thrombosis. The patient was successfully managed by the placement of an IVC filter using the VV ECMO circuit as a point of access to the circulatory system prior to cessation of VV ECMO support and decannulation.

Methodist Debakey Cardiovasc J 2020 Oct-Dec;16(4):e5-e7


Thrombosis of the left renal vein (LRV) is a rare occurrence usually associated with hypercoagulable disorders. It may also be caused by extrinsic compression due to anatomical variations. Such variations, known as nutcracker phenomenon (NP), are usually completely asymptomatic, and they have been described in three variants: a narrowed aortomesenteric angle (AMA) with entrapment of the LRV; a second, rarer variant with an anomalous retro aortic LRV compressed between the abdominal aorta (AA) and the spine (posterior nutcracker syndrome, PNCS); and a third variant with a duplicated LRV with a pre- and retroaortic course, compressed both anteriorly and posteriorly.

[Total laparoscopic retrieval of a cava filter: case series].

Angiol Sosud Khir 2020 ;26(4):149-154

Clinic #1, Volgograd State Medical University of the RF Ministry of Public Health, Volgograd, Russia.

Despite the fact that prevention and treatment of venous thromboembolic complications are based on anticoagulant therapy in cases where there are contraindications, complications, as well as in case of inefficiency of the carried out anticoagulant therapy, installation of a cava filter is indicated. The necessity of subsequent retrieval of this device from the inferior vena cava is associated with a potential risk of the development of complications. Analysed herein is a case series concerning management of 4 patients undergoing treatment from February 2015 to March 2017. Read More
