Surgical management of a penetrated greenfield inferior vena cava filter

Successful retrieval of dislocated inferior vena cava filter using double vascular sheaths docking technology: case report

BACKGROUND

Dislocation of inferior vena cava filter (IVCF) is a rare complication with potential IVC perforation and other life-threatening risks requiring early diagnosis and in-time retrieval. Most of dislocation IVCF in the past have been shelved or removed by open surgery. It is very difficult to retrieve the filters by interventional technology.

CASE PRESENTATION

Here we report a 49-year-old man suffering from dislocation of IVCF implanted due to deep vein thrombosis (DVT) in the right femoral vein. Successful retrieval of the IVCF using double sheaths docking technique was done soon after confirmation of the dislocation. Importance of monitoring and early detection of dislocation of IVCF should be emphasized to avoid further complications.

CONCLUSIONS

The double vascular sheaths docking technique can be considered as a preferential option in difficult operative situation.

Management of infected caval filter with simultaneous aortic pseudoaneurysm and retroperitoneal perforation: a case report and literature review

Inferior vena cava (IVC) filters have been reported to have complication rates up to 35%. Penetration of surrounding retroperitoneal structures is an uncommon, but potentially serious, complication, with several reports in the literature. We present a unique case of a 34-year-old intravenous drug user with infected IVC filter struts penetrating multiple structures simultaneously. Definitive operative management was necessary for removal of filter struts from the aorta, the second part of the duodenum and the iliopsoas muscle. Drainage and debridement of an associated iliopsoas abscess was performed, followed by aortic and caval reconstruction.

Surgical removal of a tilted temporary inferior vena cava filter incorporated with a large thrombus: report of a case

A 68-year-old woman was referred to our hospital with left leg edema and dull pain. Magnetic resonance imaging and enhanced computed tomography (CT) revealed a huge myoma uteri compressing the left common iliac vein, thus resulting in iliofemoral venous thrombosis. A total hysterectomy was uneventfully performed under the placement of a temporary inferior vena cava (IVC) filter. The postoperative enhanced CT-scan and cavography revealed the 90 degrees -tilted filter incorporated with a large thrombus. As an increased dose of heparin that was administered during the following week resulted in no reduction of the thrombus, a surgical removal was indicated. The infrarenal IVC was clamped proximal and distal to the filter, and the tilted filter with the large thrombus was removed through a longitudinal cavotomy. The postoperative course was uneventful, and she had no recurrence or residual symptoms for 6 months following the surgery.
