Endovascular stent grafting of traumatic aortic arch pseudo-aneurysm

South African Journal of Radiology, 2008
Endovascular stent graft repair for the treatment of dissecting thoracic aneurysms is emerging as a safe, minimally invasive and attractive alternative to surgery. This article aims to highlight the importance of computer tomography (C.T ) angiography as

Finite element modeling to predict procedural success of thoracic endovascular aortic repair in type A aortic dissectionCentral MessagePerspective

JTCVS Techniques, 2020
Objective: Thoracic endovascular aortic repair (TEVAR) is recommended for type B aortic dissection and recently has even been used in selected cases of proximal (Stanford type A) aortic dissections in scenarios of prohibitive surgical risk.

Fenestrated Aortic Stent Grafts [PDF]

Seminars in Interventional Radiology, 2007
Fenestrated stent grafts have been developed to offer an endovascular treatment option to those patients with abdominal aortic aneurysms whose infrarenal necks are anatomically unsuitable for endovascular repair with standard infrarenal devices. The ability to have customized fenestrations that will preserve flow to essential visceral arteries allows ...

Deep Learning Network‐Tailored Microenvironment Matching of 4D Bioprinting Bioactive Scaffolds for Bone Regeneration

Advanced Science, EarlyView.
A DLN dataset was built to analyze MABS composition versus in vitro/in vivo osteogenesis and angiogenesis. An MLP neural network, taking BG morphological parameters as input, extracts bioactive features from these datasets. A rabbit tibial defect model then validates 4D‐printed MABS for adaptability and bone regeneration in critical defects.

Alternating Shear Force of Respiration Regulates Cell Interactions of Fibroblasts and Macrophages to Promote Soft Tissue Integration of Chest Wall Polyetheretherketone Implants

Advanced Science, EarlyView.
Given that PEEK chest wall implants induce shear force at the soft tissue‐implant interface due to respiratory motion in the early in vivo post‐implantation stage. We confirmed that this mechanical stimulus triggers the PIEZO1/ITGB1/YAP1 signalling axis in L929 and the STAT6/p‐STAT6 pathway in RAW264.7, which in turn mediates adhesion and migration of ...

A novel foldable stent graft [PDF]

, 2004
This dissertation concerns the structural design of medical stent grafts. A new type of an innovative stent graft has been developed. Unlike the conventional stent grafts which consist of a wire mesh and a covering membrane, the proposed stent graft can ...

Thoracic Stent Graft Implantation for Aortic Coarctation with Patent Ductus Arteriosus via Retroperitoneal Iliac Approach in the Presence of Small Sized Femoral Artery

Case Reports in Cardiology, 2016
Endovascular stent graft implantation is a favorable method for complex aortic coarctation accompanied by patent ductus arteriosus. Herein, an 18-year-old woman with complex aortic coarctation and patent ductus arteriosus was successfully treated by ...

An unusual case of aortic rupture after deployment of a bare stent in the treatment of aortic dissection in a patient with giant-cell arteritis

Videosurgery and Other Miniinvasive Techniques, 2017
Giant-cell arteritis is associated with a higher risk of aortic aneurysm and aortic dissection formation. We present a women with aortic dissection type B treated with a stent graft and bare-metal stent implantation. After the stent deployment we noticed
