title: [Intimal hyperplasia growth after stenting of modified gianturco Z stent in an experimental study].
abstract: Three types of modified Gianturco Z stents, which included some solder at the bend portion in group 1, a little solder in group 2 and no solder in group 3, were placed in the jugular vein in order to evaluate the degree of intimal hyperplasia growth in five dogs. Four weeks later, venography and histological examination after venectomy were performed. Stenosis was 32.7 +/- 6.9% at the bend portion in group 1, 27.0 +/- 6.0% in group 2 and 14.0 +/- 6.5% in group 3. The results indicate that stents without solder are preferable for the venous system.
