Use of half (disarticulated) Palmaz‐Schatz stents for thrombus‐containing coronary lesions

Abstract

Coronary stenoses associated with thrombus can lead to poor angioplasty results and increased procedural complications. Stenting in the presence of thrombus is associated with an increased risk of stent thrombosis. We report eight patients in whom half a Palmaz-Schatz stent was implanted for inadequate angioplasty results owing to thrombus. Stenting resulted in improved angioplasty results; no stent thrombosis occurred.

Comparison of the sheath delivery system versus bare stenting for coronary stent implantation

“…Although clinical studies have demonstrated that the procedural success rate of Palmaz-Schatz coronary stent placement was significantly higher than balloon angioplasty [1,2], the Benestent and STRESS [4,[7][8][9]. The half-stent can be remounted on the stent delivery system to increase the SDS flexibility and still maintain the safety of the delivery sheath [10,11].…”

“…Despite their utility, the stents currently available in the United States have many limitations associated with their length and rigidity, making deployment in calcified or tortuous vessels difficult. Although clinical studies have demonstrated that the procedural success rate of Palmaz-Schatz coronary stent placement was significantly higher than balloon angioplasty [1,2], the Benestent and STRESS [4,[7][8][9]. The half-stent can be remounted on the stent delivery system to increase the SDS flexibility and still maintain the safety of the delivery sheath [10,11].…”

Comparison of the sheath delivery system versus bare stenting for coronary stent implantation

“…Although clinical studies have demonstrated that the procedural success rate of Palmaz-Schatz coronary stent placement was significantly higher than balloon angioplasty [1,2], the Benestent and STRESS trials showed that stent placement failed in 10 of 259 patients (3.9%) and three of 205 patients (1.5%), respectively, because of an inability to cross the lesion. To facilitate stent delivery in difficult cases, several reports describe that cutting the Palmaz-Schatz stent in half has several advantages [4,[7][8][9]. The half-stent can be remounted on the stent delivery system to increase the SDS flexibility and still maintain the safety of the delivery sheath [10,11].…”

Coronary stenting with the half (disarticulated) Palmaz-Schatz stent: Immediate results and six-month follow-up

“…The half stent is particularly suitable for ostial stenoses, relapsing short stenoses, localized dissection or stenoses distal to curves, and twisting coronary segments in which the whole stent would be difficult to place. However, few data exist about the half Palmaz-Schatz stent and, furthermore, no data exist regarding follow-up [9][10][11][12].…”
