Tissue Response to Covered Wallstents
Journal of Vascular and Interventional Radiology, 1998To evaluate and compare the healing response related to two types of graft-covered Wallstents (WSs) and an uncovered WS in the canine iliac artery.Eight bare mesh WSs, 10 polyethylene terephthalate interbraided WSs (PET-WSs), and six polytetrafluoroethylene covered WSs (ePTFE-WSs) were placed in the iliac arteries of 12 dogs. Arteriograms were obtained

Duodenal Perforation by a Wallstent
Endoscopy, 2000Endoscopic and/or radiological insertion of metallic mesh stents has recently been described as an alternative to palliative bypass operation in patients with gastric outlet obstruction caused by advanced malignant disease. We report a complication caused by migration and late perforation of the duodenum by a Wallstent, which raised concerns about the ...

Complication of a venous wallstent
Australasian Radiology, 1999A case is reported here of effort‐related thrombosis of the axillary and subclavian veins (Paget–Schrotter syndrome) treated primarily with a combination of thrombolysis, percutaneous balloon angioplasty (PTA) and stent insertion, but without immediate rib resection.

Removal of Self Expandable Metallic Wallstents
Gastrointestinal Endoscopy, 2004The self-expandable metallic stent is increasingly being used for management of malignant biliary strictures. In certain clinical situations, it also may be an alternative treatment for benign strictures. The ability to remove a metallic stent would be advantageous to the management of many biliary strictures, regardless of etiology.Stent removal was ...

Complications of Percutaneously Inserted Biliary Wallstents
Journal of Vascular and Interventional Radiology, 1993Complications were assessed during and after percutaneous Wallstent endoprosthesis insertion in patients with inoperable malignant biliary obstruction.Two hundred seven Wallstents were inserted in 176 patients: 74 had hilar strictures and 102 had distal strictures.

An Unusual Complication of a Colonic Wallstent
CardioVascular and Interventional Radiology, 2004We report a case of delayed perforation of normal colonic wall by the wire tips of an enteral Wallstent, which had successfully been used to treat a malignant obstruction of the sigmoid colon. Perforation occurred 5 days following insertion and despite surgery, resulted in fatality.

Urology, 1994
The wallstent has been proved to be effective for the treatment of bulbar urethral strictures. Only a few failures are reported in the literature. We present a case of a patient with a recurrent stricture after wallstent implantation. The recurrence has been managed successfully with gradual dilation and with the insertion of an inner stent inside the ...

Heterogeneous surface properties on wallstents
Surface and Interface Analysis, 2009Abstract Wallstent has been successfully used to open up clogged peripheral arteries. CoCr alloy is the preferred metal for the construction of wallstent. Unfortunately, major complications such as in‐stent intimal hyperplasia,stent obstruction, and stent stricture are often reported, and these complications could be related to the ...

Cardiovascular and Interventional Radiology, 2000
Four patients with malignant obstruction of the common bile duct had been treated with uncovered Wallstents and suffered from a reobstruction after 2-13 months (mean 5.3 months). Repeat cholangiography revealed severe stenosis of the stent lumen caused by tumor ingrowth through the mesh.
