Endovascular iliac vein reconstruction through an obstructive pelvic nodal recurrence of urothelial carcinoma

CVIR Endovascular, 2018
Background Chronic venous occlusion is common particularly in cancer patient due to hypercoagulate state associated with venous compression. Treatment options include endovascular management with venoplasty and stenting. Recanalization can be challenging

Deep Venous Stenting Improves Healing of Lower Extremity Venous Ulcers

Annals of Vascular Surgery, 2022
Long standing, recalcitrant venous ulcers fail to heal despite standard compression therapy and wound care. Stenting of central veins has been reported to assist in venous ulcer healing. This study reports outcomes of deep venous stenting for central venous obstruction in patients with recalcitrant venous ulcers at a single comprehensive wound care ...

Dural sinus septum: an underlying cause of cerebral venous sinus stenting failure and complications

Stroke and Vascular Neurology
Objectives The presence of dural sinus septum has long been identified anatomically but is often neglected for its clinical significance. Our findings revealed the association of dural sinus septum with venous sinus stenting failure and complications ...

Adaptive 4D‐Printed Vascular Stents With Low‐Temperature‐Activated and Intelligent Deployment

Advanced Functional Materials, EarlyView.
Microarchitected coronary artery stents were fabricated using a polycaprolactone (PCL)‐based shape memory polymer (SMP) composite via projection micro‐stereolithography (PµSL) 4D printing. By incorporating diethyl phthalate (DEP) as a plasticizer, the thermal transition temperature (Ttran) was modulated to about 37°C, enabling rapid and autonomous ...

A Versatile Engineering Platform for the Fabrication of Prosthetic Venous Valves Using Electrospinning

Advanced Healthcare Materials, EarlyView.
Percutaneous prosthetic venous valves are fabricated by embedding stents in an electrospun matrix that extends luminally to form leaflets. The design shields leaflets from hyperplastic cells, isolates struts from blood contact, and avoids discrete anchoring points.
