Inferior Vena Cava Filter Erosion Causing Symptomatic Obstructive Hydronephrosis.

Inferior vena cava (IVC) filters are used to prevent pulmonary embolism in patients at risk for deep vein thrombosis. While rare, complications such as filter migration, fracture, or erosion into adjacent structures can occur. Prior research has shown that IVC filter erosion into the urinary tract is uncommon but has been documented. It was already known that such erosion can lead to obstructive uropathy, including hydronephrosis. However, no prior work had resolved the specific management strategies for symptomatic cases involving the ureter. That uncertainty drove the need for case reports that describe both diagnosis and intervention. No prior work had clearly outlined the combined use of percutaneous and endovascular approaches in these scenarios. This gap motivated the documentation of a case where a multidisciplinary approach was used. No prior work had demonstrated the safety of endovascular removal in such cases. This gap motivated the presentation of a unique management approach.

The aim of this case report is to describe the diagnosis and treatment of a patient with symptomatic obstructive hydronephrosis caused by IVC filter erosion into the ureter. The specific problem addressed is the management of a rare but clinically significant complication of IVC filters. The motivation stems from the lack of standardized protocols for such cases. The authors propose that multidisciplinary interventions may offer effective solutions. The study focuses on the integration of percutaneous, endovascular, and endourologic techniques. The problem is the risk of major surgery in patients with IVC filter-related complications. The authors suggest that endovascular removal may be a viable alternative. This case highlights the importance of timely diagnosis and coordinated care.

The study involved a 59-year-old woman with a history of IVC filter placement. Diagnostic imaging revealed right hydronephrosis and obstruction from filter erosion into the proximal right ureter. The authors used a combination of percutaneous nephrostomy, endovascular intervention, and endourologic techniques. Percutaneous procedures were performed to manage hydronephrosis and relieve obstruction. Endovascular techniques were used to safely remove the IVC filter limb. Endourologic procedures were employed to assess and treat ureteral involvement. The authors coordinated multiple specialties to avoid major surgery. The approach was guided by imaging findings and clinical symptoms. The methods were tailored to the patient’s specific anatomical and clinical situation.

The patient presented with right flank and abdominal pain and was found to have right hydronephrosis. Imaging confirmed erosion of an IVC filter limb into the proximal right ureter. Percutaneous nephrostomy was performed to relieve hydronephrosis. Endovascular removal of the IVC filter limb was successfully executed. Endourologic procedures confirmed resolution of ureteral obstruction. The patient’s symptoms improved following these interventions. No major surgical procedures were required. The combined approach effectively managed the obstructive complication. The results suggest that endovascular removal is a feasible option in such cases.

The authors conclude that IVC filter erosion into the ureter can cause obstructive hydronephrosis. They propose that endovascular removal is a safe and effective treatment option. The study supports the use of multidisciplinary interventions in managing such rare complications. The authors suggest that early diagnosis and coordinated care improve outcomes. They emphasize the importance of avoiding unnecessary major surgery. The findings suggest that endovascular techniques may be preferred in selected cases. The authors propose that endovascular removal should be considered when the urinary tract is involved. The conclusions are based on the successful management of this specific case.
