Background: Inferior vena cava thrombosis (IVCT) is a rare clinical condition. Herein, we report eight cases of IVCT in Taiwanese patients.Methods: Eight Taiwanese patients diagnosed with IVCT between May 2012 and December 2019 were included in this study. The patients’ demographics, presenting characteristics, additional sites of venous thromboembolism, extent of IVCT, prothrombotic risk factors, and IVCT-related adverse events were evaluated.Results: All eight patients with IVCT presented with other coexisting venous thromboembolic manifestations, such as deep venous thrombosis (DVT, 100%) or pulmonary embolism (62.5%). The clinical presentations, including DVT in both lower extremities coexisting with the dilatation of the superficial veins of the abdominal wall (50%), were reported. No congenital anomalies of the inferior vena cava (IVC) were noted. Various thromboembolic risk factors, such as unretrieved IVC filters (25%), pregnancy (37.5%), lupus anticoagulants (37.5%), surgery (25%), antithrombin deficiency (12.5%), hemoglobin H disease (12.5%), and essential thrombocythemia (12.5%), were identified. All patients were administered anticoagulants. One patient (12.5%) developed post-thrombotic syndrome. No mortality was reported in our cohort. Conclusions: This is the first report of IVCT in Taiwanese patients. Typical clinical features of IVC occlusion coexisting with predisposing factors of venous thrombosis, such as lupus anticoagulants, pregnancy, or unretrieved IVC filters, could indicate a diagnosis of IVCT. Moreover, IVCT presenting as a complication resulting from the unretrieved IVC filter was observed, highlighting the potential risks of chronic indwelling filters.

Recanalization of an Occluded Vena Cava Filter and Iliac Veins with Kissing Stents to Treat Postthrombotic Syndrome with a Venous Stasis Ulcer

Inferior vena cava filters (IVCFs) are effective in preventing pulmonary embolism and their usage has rapidly increased over the past decades. However, complications have also significantly increased, as IVCF occlusion causes serious chronic venous insufficiency. Herein, we report a case of infrarenal IVCF occlusion that was successfully treated with the introduction of kissing stents through the IVCF into both iliac veins. A 54-year-old male presented with non-healing ulcers on his left leg. He had undergone IVCF implantation and warfarin medication due to deep vein thrombosis 4 years earlier in another hospital. Computed tomography (CT) revealed the filter-bearing IVC occlusion. Endovascular IVCF removal was attempted but failed. Kissing stents were deployed across the IVCF and extended into both iliac veins. Cone beam CT showed well-deployed stents just behind the occluded IVCF. Venous flow was restored without complications, and the recurrent ulcer healed immediately.

Inferior vena cava thrombosis (IVCT) is rare and can be under-recognized. However, the associated complications and mortality may be severe. We report the first case series of IVCT observed in Taiwan with a brief literature review. Eight Taiwanese patients with IVCT between May 2012 and December 2019 were enrolled in this study. Deep venous thrombosis (DVT, 8/8) and pulmonary embolism (5/8) were reported. Various risk factors were identified, including an unretrieved inferior vena cava (IVC) filter, pregnancy, surgery, presence of lupus of anticoagulants, essential thrombocythemia, antithrombin deficiency, and hemoglobin H disease. Of note, four of our patients experienced complete IVC thrombosis with bilateral lower extremity swelling (due to DVT) and abdominal wall superficial venous dilatation, while four other patients presented with partial IVCT and unilateral DVT. The etiology, clinical characteristics, presentations, diagnosis, and treatment of IVCT were reviewed.
