Recently, carotid artery stenting (CAS) has been reported to be an alternative of carotid endarterectomy (CEA) for internal carotid artery (ICA) stenosis due to the improvement of protection devices. In general, the transfemoral approach has been chosen for CAS because of the sizes of the devices. However, the transfemoral route seems to be unavailable or at high risk, in cases of severe atherosclerotic changes or aneurysm of the femoral, iliac artery or aorta, or after bypass graft placement. In this report, we presented 5 patients who underwent CAS using the transbrachial approach. The mean stenotic rate of 84% before treatment was reduced to 14% after the procedures. The 30-day morbidity and mortality were both 0%. Major local complications at the puncture site were not encountered. There has been no stroke nor death during a mean follow-up period of 6 months. We suggest that CAS via transbrachial route is an effective and safe treatment for ICA stenosis, by use of low-profile devices and bi-plane DSA equipment, especially in patients who are not eligible for the transfemoral access.

Magnetic resonance angiography in diagnostic long-term follow-up of primary patency of the MOTIV drug-eluting bioresorbable vascular scaffold in the region below the knee: 5 years of experience.

Purpose: Treatment of peripheral artery disease (PAD) in the region below the knee (BTK) is dissatisfying as failure of treated target lesions (TLF) is frequent and diagnostic imaging is often challenging. In the BTK-region metallic drug-eluting stents (mDES) yielded best results concerning primary patency (PP), but also annihilate signal in magnetic resonance angiography (MR-A). A recently introduced non-metallic drug eluting bioresorbable Tyrocore® vascular scaffold (deBVS), that offers an option for re-treatment of lesions due to its full degradation within 3-4 years after placement, was investigated with respect to its compatibility with MR-A to unimpededly depict previously treated target lesions.

Pancreaticojejunostomy (PJ) is a critical step in pancreaticoduodenectomy (PD), often complicated by the risk of postoperative pancreatic fistula (POPF). This video report demonstrates a novel robotic PJ technique employing a self-expandable metallic stent. The method involves the use of the Da Vinci Xi robotic system and the WallFlex™ Biliary RX Stent for improved anastomotic support, particularly in high-risk cases defined by soft pancreatic texture and narrow duct diameter (<3 mm).

Objectives: The impact of long-term complications after robotic hybrid coronary revascularization (HCR), including persistent angina, repeat revascularization, and myocardial infarction (MI), remains limited. This study aims to determine the risk factors for coronary events after robotic HCR and their time-varying effects on outcomes.
Methods: We identified all consecutive patients who underwent robotic HCR at our institution.

Anterior choroidal artery (AChoA) aneurysms pose a challenge for both endovascular and clipping procedures. The eloquent territory supplied by the parent vessel has limited collateralization and its compromise can lead to significant morbidity. This study aims to analyze the clinical outcomes and procedure-related complications of clipping and endovascular treatment of AChoA aneurysms to aid physician decision making.

Objective: The gold standard imaging modality for assessing crural arterial disease is digital subtraction angiography (DSA). Using DSA, the operator can estimate the diameter and degree of stenosis and determine the diameter of the balloon. Since these measures are estimates, it allows for interobserver and intraobserver variability.
