Article Abstract
Background: Conventional recanalization techniques may fail in patients with completely occluded superior vena cava (SVC).
Aim: To analyze the effectiveness and complications of sharp recanalization for completely occluded SVC.
Methods: This was a retrospective study of patients that underwent puncture and recanalization of the SVC between January 2016 and December 2017 at our hospital. Sharp recanalization was performed using the RUPS-100 system. The patients were followed for 12 mo. The main outcomes were the patency rate of SVC and arteriovenous fistula flow during dialysis.
Results: The procedure was successful in all 14 patients (100%). Blood pressure in the distal SVC decreased in all 14 cases (100%) from 26.4 ± 2.7 cmHO to 14.7 ± 1.3 cmHO ( < 0.05). The first patency rates of the SVC at 24 h and at 3, 6, 9 and 12 mo after sharp recanalization were 100%, 92.9%, 85.7%, 78.6% and 71.4%, respectively. There were two (14.3%) severe, one (7.1%) moderate and one (7.1%) minor complication. The severe complications included one case of pericardial tamponade and one case of hemothorax.
Conclusion: The results suggest that sharp recanalization can be an additional tool to extend or renew the use of an occluded upper extremity access for hemodialysis. This could be of use in patients with long-term maintenance hemodialysis in whom the maintenance of central venous access is often a challenge.

Superior vena cava (SVC) occlusion in hemodialysis patients presents significant therapeutic challenges, particularly when complicated by stent migration. Sharp recanalization may serve as a salvage intervention for refractory cases though high-risk. Here, we present a 72-year-old male with stent migration-induced recurrent SVC syndrome.

Background: Reports of child and young adult superior vena cava (SVC) stent placement, safety, and long-term patency are limited, particularly in children without congenital heart defects (CHDs).
Objective: To characterize technical success, safety, and long-term outcomes of SVC stent placement in children and young adults without co-existing congenital heart defects. Additionally, to demonstrate the ability of SVC stent placement to maintain central venous access in patients with difficult access.

Central venous occlusive disease (CVOD) is a challenging problem that frequently leads to the abandonment of an otherwise functional hemodialysis access. Prior central venous access, including tunneled dialysis catheters, are a common predisposing factor. CVOD is typically preceded by an interval period of stenosis and often amenable to simple balloon angioplasty.

Background: The use of intravascular ultrasound (iUS) has been shown in multiple single-center retrospective studies to decrease procedure time, radiation exposure, and needle passes compared to conventional fluoroscopic guidance in the creation of a transjugular intrahepatic portosystemic shunt (TIPS). However, there are few data regarding the impact of imaging guidance modality choice on clinical outcomes.
Aim: To determine the impact of iUS fluoroscopic guidance during creation of a TIPS on procedural metrics, liver injury, shunt patency and mortality.

Venous webs of the inferior vena cava (IVC) and hepatic veins are rare and can result in Budd-Chiari syndrome. Included images of classic venous webbing are from a 60-year-old woman who presented with abdominal distension/pain, lower extremity edema, elevated liver tests, and ascites due to multifocal venous webbing of the IVC and right hepatic vein. The patient was successfully treated with IVC venous stent placement.
