Superior vena cava obstruction (SVCO) and associated thrombus formation can occur in patients with upper mediastinal or right apical masses. While stenting is useful in relieving obstruction, it can facilitate the passage of upper extremity deep vein thrombus to the pulmonary arterial tree, resulting in a potentially fatal pulmonary embolism (PE). We present a case that illustrates a novel technique, which protects the patient from PE while also relieving the SVCO. This involves placing an inferior vena cava filter in an inverted position within a superior vena cava (SVC) stent to capture emboli. This procedure offers a potentially lifesaving endovascular therapeutic option to patients who would otherwise be deemed unsuitable for SVC stenting.

Introduction: Extrauterine recurrent metastasis of Low-grade endometrial stromal sarcoma (LG-ESS) to major blood vessels is largely rare with few reported cases.
Case: Herein, we present a case of a 51-year-old female with recurrent LG-ESS that has metastasized after 12 years to the inferior vena cava (IVC) and extended into the right atrium and common iliac veins. Computed tomography showed an intracardiac larger thrombus within the right atrium extending into the inferior vena cava and common iliac veins.

During bidirectional cavo-pulmonary anastomosis (bidirectional Glenn; BDG), the thymic tissue is often excised to facilitate the exposure of the superior vena cava and its junction with the innominate vein. Subsequently, it is discarded. Since the last two decades, the lead author (ST) has pursued anchoring the excised thymus in its position by suturing it to the opposite unexcised thymic lobe.

Purpose: To evaluate the impact of corticosteroid premedication on the performance of adrenal vein sampling (AVS) in patients with primary aldosteronism (PA) and allergy to iodinated contrast media (ICM).
Materials And Methods: Patients who underwent AVS for PA, between September 1990 and October 2023, were retrospectively identified. Patients with ICM allergy who received corticosteroid pre-medication were matched 1:1 with patients without contrast allergy.

Purpose: Report 2-year outcomes from a prospective, multicenter, non-randomized, single-arm study designed to further assess the safety and effectiveness of the Celect and the Günther Tulip Vena Cava Filters.
Materials And Methods: The BLIND study enrolled patients requiring temporary or permanent IVC filter placement for the prevention of pulmonary embolism (PE). The primary effectiveness endpoint was the rate of technical placement success and 12-month freedom from new symptomatic PE while a filter was indwelling.
