The Incidence of Arterial Stent Fractures with Exclusion of Coronary, Aortic, and Non-arterial Settings

Abstract

The incidence of stent fracture, its location of placement, and type of stent used were diverse across studies. Stent fracture may cause clinical deterioration especially in the femoropopliteal segment, and it should be detected before clinical manifestation appears. Further studies with larger study population involving new type of stents for a longer follow up period are warranted.

Patient specific finite element analysis results in more accurate prediction of stent fractures: Application to percutaneous pulmonary valve implantation

“…Despite many technical improvements and strict test protocols prior to market introduction, stent fracture has been recognised as a common complication following stent implantation for all cardiovascular applications (Breinholt et al, 2008;Rits et al, 2008;Lim et al, 2008). Percutaneous pulmonary valve implantation (PPVI) -a successful technique introduced in 2000 to treat right ventricular outflow tract (RVOT) dysfunction (Bonhoeffer et al, 2000;Lurz et al, 2008) -is also subjected to this potentially adverse event.…”

Safety, Clinical Outcome, and Fracture Rate of Femoropopliteal Stenting Using a 4F Compatible Delivery System

“…21 Stent fractures have been extensively investigated in many vascular territories and were noted to be one of the most common in the femoropopliteal arteries, with a prevalence of 2e65%. 22 Here, a 26% fracture rate was reported after an average follow up of 25 months. A literature search for the fracture rates of 4F Astron Pulsar and Pulsar-18 stents revealed only one study (the 4-EVER trial).…”

“…Calcification due to changes in the regional wall stiffness and creating excessive focal pressure on certain parts of the stent has already been demonstrated to play a role in the development of stent fracture. 22 …”

Radiation-Induced Rupture of the Superficial Femoral Artery: A Case Report

“…Several groups have reported excellent results with CFA stenting with survival and amputationfree survival at 1 year estimated at 96%, 8 but the incidence of stent fractures due to joint's mobility is still high. 9,10 The new generation self-expanding nitinol stents are considered to behave favorably because they offer increased resistance to repeated external forces due to their unique structure and design. VIBRANT trial 11 showed that the rate of stent fractures in the SFA were significantly more common in bare nitinol stents (50.0%) than in the VIABAHN endoprostheses (2.6%).…”
