Inferior Vena Cava Filter Long Term Complications and Retrieval Techniques: A Case Series and Literature Review
Introduction and Importance Long-term mechanical complications after inferior vena cava (IVC) filter placement include embedded or tilted filters, erosion of the vena cava, filter thrombosis. In the setting of caval thrombosis, patients may subsequently develop venous hypertension and post-thrombotic syndrome (PTS). Here we present three unique cases of IVC filter complications and surgical management. Case Presentation A 30-year-old female presented with acute abdominal pain, revealing a duodenal perforation caused by an IVC filter eroding into her duodenum. A 42-year-old female with an IVC filter in place for 20 years due to a prior pulmonary embolism underwent laser-assisted retrieval of the filter due to concerns of caval adherence. A 48-year-old male with a history of DVT, venous stasis ulcer, and an IVC filter presented for filter retrieval. Clinical Findings and Investigations The surgical techniques described in this report include complicated IVC filter retrieval, performed in cases of filter complications including migration, fracture, duodenal perforation and IVC thrombosis resulting in PTS. One case, requiring open retrieval, is explained and the surgical technique is provided. There are images and videos of these procedures to enrich the learning experience. Intervention and Outcomes The surgical techniques described in this report include complicated inferior vena cava filter retrieval, performed in cases of filter complications including migration, fracture, duodenal perforation and IVC thrombosis. One case, requiring open retrieval, is explained and the surgical technique is provided. There are images and videos of these procedures to enrich the learning experience. Relevance and Impact Endovascular retrieval of long-term complicated IVC filters is challenging, but it can be a safely performed in many patients. However, open surgery may be necessary in selected patients

Extra-anatomic bypasses as perfusion alternatives in the treatment of complex thoracoabdominal aortic disease
The management of thoracoabdominal aortic aneurysms (TAAA) presents significant challenges for vascular and cardiothoracic surgeons due to the risk of ischemic complications. Various strategies have been implemented over time, including open repair with or without left heart bypass (LHB), endovascular, and hybrid approaches. Here, we explore the application of temporary extra-anatomic bypasses (TEAB) as a technique for complex open TAAA repair when the traditional standard of care is not feasible (i.e. Unavailability of LHB) or indicated (i.e. contraindication for systemic heparinization for LHB).
Case 1 is an undomiciled 59-year-old male with a chronic type B dissection (CTBD) and degenerative TAAA with failed attempt at endovascular repair at an outside institution. An open repair of the visceral segment was performed with TEAB due to risk of impending rupture, prior failed endovascular repair, and unavailability of cardiac surgery. Additionally, a staged TEVAR was planned for treatment of the thoracic portion of the CTBD in two weeks’ time. The patient experienced sudden chest pain 10 days following the TAAA repair, prompting urgent TEVAR. No complications were observed. Case 2 is a 65-year-old male with a type 2 TAAA who underwent an open repair with the use of TEAB. Technical success was achieved with no complications.
TAAA repair poses significant challenges regardless of the approach selected. However, the use of TEAB has shown promise in ensuring adequate perfusion of vital organs during complex repair when LHB is not an option. Preoperative planning is essential to minimize ischemic time and reduce complications. Studies have shown favorable outcomes with TEAB, however, evidence relies only on small series and case reports.
The use of TEAB is a valuable technique for safeguarding organ perfusion during open repair of TAAA. While further research and experience are needed, TEAB offers a promising alternative for cases where traditional approaches are not available. Continued exploration and documentation of TEAB in current literature will contribute to optimizing TAAA management strategies
