Cryopreserved Saphenous Vein Allograft in Patients With Critical Limb Ischemia for Peripheral Revascularization (LIMBSAVE)
Prospective, Multicenter, Primary Below the Knee Bypass Evaluation With CryoVein® Cryopreserved Saphenous Vein Allograft in Patients With Critical Limb Ischemia
Descripción general del estudio
Estado
Descripción detallada
A minimum of 50 CVA will be implanted in enrolled patients at up to 6 participating sites. The Study will include prospective evaluations on these patients at discharge, 1, 3, 6, 9, 12, 18 and 24 months following surgery. The window for follow-up visits is ± 2 weeks for each time point. All Study patients will be expected to participate in all follow-up evaluations unless precluded by patient death.
Patient status and graft performance data will be collected on all patients consented and enrolled into the Study. The primary endpoint of the Study will be limb salvage. The secondary endpoints of the Study will include primary patency, secondary patency, morbidity and mortality per the same reporting standards.
Patient attributes (age, gender, etc.) and preoperative assessments (indication for surgery, medical history) will be summarized using descriptive statistics. Graft performance will be presented as freedom from an event endpoint (patient death, graft complication, amputation, graft explant) as calculated by the Kaplan-Meier method. Log Rank and Cox Regression will be utilized for comparison between subgroups of the patient population. Statistical software will be used to compile and analyze all submitted clinical data.
The method of data reporting may include, but is not limited to, a description of the sample population, frequency distributions of patient demographics, allograft statistics, and follow-up percentages, summary of event data, correlation analysis, and actuarial analysis
