Randomized Trial Comparing Two Devices: The Palmaz‐Schatz Stent and the Strecker Stent in Bail‐Out Situations

Abstract

Both Palmaz-Schatz and Strecker stents are equally effective in restoring vessel patency in bail-out situations. The incidence of complications is high and similar for both stents if they were used after failed prolonged balloon inflations. Differences in design and material do not seem to influence the results.

Bailout coronary stenting without anticoagulation or intravascular ultrasound guidance: Acute and six-month angiographic results in a series of 120 consecutive patients

“…The final results of the French Registry study, including 2,900 patients, confirm the preliminary results: the subacute thrombosis rate after bailout stenting is higher than nonbailout stenting (4.76% versus 1.76%, P 0.01) [5]. In several recently published series, acute closure of the stented vessel in bailout situations remains high, ranging from 7% to 16% [9][10][11][12][13][14].…”

A comprehensive review of biological and materials properties of Tantalum and its alloys

“…The Strecker stents were quickly endothelialized in a canine model with almost complete endothelial cell coverage observed as early as 3 weeks. 39 Upon moving to clinical studies, the use of the Strecker Ta stents was established in various arteries including coronary, 35 femoro-popliteal, 36 iliac, 37 and renal arteries. 38 Hausegger et al 37 The goal of this study was to assess whether the differences in stent material (316 L SS vs. Ta) and stent design influenced the clinical outcome.…”

“…All three stents were determined as effective in the treatment of complicated iliac artery occlusive disease. In another clinical study, Reifart et al 35 compared a 316 L stainless steel Palmaz‐Schatz stent and the Ta Strecker stent in 50 patients with 25 patients in each stent group. The goal of this study was to assess whether the differences in stent material (316 L SS vs. Ta) and stent design influenced the clinical outcome.…”

“…Another Ta stent (Strecker) was also investigated initially in animal studies 34 and later in clinical trials 35–38 . The Strecker stent is made of a single 0.07 mm Tantalum filament knitted into a series of loosely interwoven loops.…”

“…The Strecker stents were quickly endothelialized in a canine model with almost complete endothelial cell coverage observed as early as 3 weeks 39 . Upon moving to clinical studies, the use of the Strecker Ta stents was established in various arteries including coronary, 35 femoro‐popliteal, 36 iliac, 37 and renal arteries 38 . Hausegger et al 37 treated a total of 82 iliac artery lesions in 79 patients with 3 different stents (Palmaz 316 L stainless steel stent, cobalt‐alloy stainless steel Wall stent, and Ta Strecker stent) and observed the patients for over a period of more than 2 years.…”
