The study reports our single center experience in transulnar coronary interventions in 122 consecutive cases. Success rate was 85.2%. Vascular complications were low (5.7%) and minor (6 hematomas and 1 pseudoaneurysm treated by compression). Transulnar catheterization is feasible and safe. It represents a useful alternative to the transradial approach in selected cases.

Background: Hepatic artery infusion pump (HAIP) chemotherapy is a locoregional treatment for intrahepatic malignancies. HAIPs are surgically implanted, and the catheter tip is typically inserted into a ligated gastroduodenal artery stump. Potential complications at the catheter insertion site include dehiscence, pseudoaneurysm or extravasation, and adjacent hepatic arterial stenosis and thrombosis.

Endovascular treatment (EVT) for patients with lower extremity artery disease is widely used as a less invasive alternative to surgical bypass. Recently, transradial artery intervention has gained popularity owing to its minimally invasive nature. The distance from the radial artery to the target vessel is critical for success; however, effective pre-assessment methods have not yet been established.

Aims: This study aims to verify the feasibility and safety of percutaneous coronary intervention (PCI) after a distal transradial approach (dTRA) with radial artery occlusion (RAO) recanalization.
Methods: Between July 2018 and January 2022, 30 patients underwent PCI following attempted RAO recanalization via dTRA. Among these cases, the target radial arteries could not be recanalized in five patients, necessitating alternative vascular access.

Vascular access for coronary, peripheral, and structural interventions has changed significantly over the past two decades. The evolving demand for both large-bore access for valvular interventions and mechanical support devices, and for safer access for coronary interventions, in patients with comorbidities have driven progress in these areas. This review will provide an overview of the techniques of arterial access in the femoral, forearm (radial and ulnar), and alternative (transcarotid, transaxillary, and transcaval) locations based on the latest evidence and experience.

Backgrounds And Objectives: The distal radial access (DRA), a potential alternative to the trans-radial approach (TRA), may offer advantages in terms of access site complications due to its smaller vessel diameter, especially for high bleeding risk (HBR) patients. This study aims to investigate the feasibility of DRA in HBR patients.
Methods: Based on data from the KODRA registry, a prospective, multicenter cohort, this study analyzed 1,586 patients who underwent successful percutaneous coronary intervention (PCI) via DRA.
