The aim of this study was to assess a venous compression technique that is performed with contrast material-enhanced peripheral magnetic resonance (MR) angiography to reduce venous enhancement. Healthy volunteers, as well as patients with correlating digital subtraction angiographic (DSA) findings, were examined. Venous compression was accomplished by placing a cuff at the midfemoral level unilaterally. Arterial signal-to-noise and contrast-to-noise ratios indicated no significant differences between compressed and noncompressed legs. Venous overlay was substantially reduced in the compressed legs. MR angiography with venous compression yielded diagnostic image quality and results that had excellent correlation with DSA findings. High-spatial-resolution peripheral MR angiography of improved diagnostic quality appears feasible, even with long data acquisition times.

Background: Deep vein thrombosis (DVT) of the lower limb is a significant clinical challenge with the potential for recurrence, which can lead to increased morbidity and reduced quality of life.
Methods: A retrospective case-control study was conducted involving 367 patients diagnosed with lower limb DVT from June 2020 to June 2023. Patients were categorized into a recurrence group ( = 121) and a non-recurrence group ( = 246) based on DVT occurrence.

Intracranial solitary fibrous tumors (SFTs) and hemangiopericytomas (HPCs) are rare, aggressive tumors typically found along the dural sinuses. Despite their aggressive nature, complete surgical resection remains the most significant factor in reducing recurrence and improving survival. Here, we present the case of a 32-year-old male patient who presented with a new-onset headache and vertigo.

Objectives: To evaluate the efficacy and safety of purse-string sutures (PSS) compared with manual compression for access hemostasis in children with atrial septal defects (ASDs) after large-caliber venous delivery sheaths removal.
Methods: We conducted a retrospective clinical data review of 271 children with ASDs who underwent transcatheter device closure through large-caliber venous delivery sheaths (≥ 8 Fr) at our institution from January 2018 to January 2023. The PSS group (n = 144) was compared to the control group (n = 127), which underwent manual compression for femoral venous hemostasis after sheath removal, focusing on hemostatic time, limb braking time, bed rest time, hospital stay, and vascular access complications.

Nutcracker syndrome (NCS) is an uncommon vascular condition caused by the compression of the left renal vein (LRN), which may result in venous hypertension and clinical symptoms, including hematuria, flank pain, and pelvic congestion. This report describes the case of a 30-year-old woman with recurrent painless macroscopic hematuria, ultimately diagnosed with NCS based on clinical and radiological findings. Computed tomography (CT) angiography revealed a reduced aortomesenteric angle and LRN compression without signs of severe venous hypertension or collateral circulation.

Superior vena cava (SVC) syndrome is a result of impaired blood flow from the SVC to the right atrium, leading to venous congestion in the head and neck. It can be caused by clotting disorders or compressive tumors of the head and neck but has become more prevalent in the setting of implantable devices such as pacemakers. As such, managing these patients can present challenges for physicians who have to account for SVC syndrome as well as their underlying condition requiring an implantable cardiac device.
