Purpose: To assess the technical feasibility and efficacy of the rendezvous technique, a type of subintimal retrograde wiring, for the treatment of long-segmental chronic total occlusions above the knee following unsuccessful standard angioplasty.
Methods: The rendezvous technique was attempted in eight limbs of eight patients with chronic total occlusions above the knee after standard angioplasty failed. The clinical symptoms and ankle-brachial index were compared before and after the procedure. At follow-up, pain relief, wound healing, limb salvage, and the presence of restenosis of the target vessels were evaluated.
Results: The rendezvous technique was performed successfully in seven patients (87.5%) and failed in one patient (12.5%). Foot pain improved in all seven patients who underwent successful treatment, with ankle-brachial indexes improving from 0.23 ± 0.13 before to 0.71 ± 0.09 after the procedure (P < 0.001). At the end of the follow-up period, the visual analogue scale improved from 6.86 ± 1.57 to 1.57 ± 1.27 (P < 0.001). Non-healing ulcers in three patients either healed (n = 2) or improved (n = 1). No major amputation was necessary. Kaplan-Meier analyses revealed that stenosis-free rate was 83.3% at six months and 41.7% at 12 months.
Conclusion: The rendezvous technique is a feasible and effective treatment for chronic total occlusions above the knee when standard angioplasty fails.

Background And Aims: Difficult biliary cannulation (DBC) is a marker for prolonged procedure time and increased adverse event rate (AER) during endoscopic retrograde cholangiopancreatography (ERCP). We previously showed that EUS-guided rendezvous procedure (EUS-RV) had a higher single session success rate than precut papillotomy (PcP) in DBC patients. The present randomized study aims at comparing the technical success and AER between the two approaches.

Background: Advancing the retrograde microcatheter (MC) into the antegrade guide catheter during retrograde chronic total occlusion (CTO) percutaneous coronary intervention (PCI) can be challenging or impossible, preventing guidewire externalization.
Objectives: To detail and evaluate all the techniques focused on wiring to achieve intubation of the distal tip of a microcatheter, balloon, or stent with an antegrade or retrograde guidewire, aiming to reduce complications by minimizing tension on fragile collaterals during externalization and enabling rapid antegrade conversion in various clinical scenarios.
Methods: We describe the two main techniques, tip-in and rendezvous, and their derivatives such a facilitated tip-in, manual MC-tip modification, tip-in the balloon, tip-in the stent, deep dive rendezvous, catch-it and antegrade microcatheter probing.

We present a case of a 52-year-old man with chronic toxic pancreatitis and history of multiple hospital admissions secondary to pancreatitis exacerbation. Due to persistent respiratory symptoms a thoracoabdominal computerized tomography (CT) was performed. The CT showed a new significant right pleural effusion as well as inflammatory changes secondary to acute pancreatitis.

Purpose: To demonstrate the Modified Balloon Nose Cone Technique to avoid passage of the aortic valve in endovascular branched arch repair.
Technique: The technique is demonstrated in a 54-year-old patient after previous open repair of the ascending aorta and mechanical aortic valve replacement due to type A aortic dissection. The delivery system of a custom-made stent-graft with 3 inner branches was modified by subtotally sawing off its nose cone.

Introduction: Transurethral resection is the main method for diagnosing and staging bladder cancer, which allows to determine treatment tactics. Tumors located in the area of the ureteric orifice is an important clinical problem.
Aim: To describe our experience in the treatment of ureteral obliterations after transurethral resection of the bladder tumors.
