April 25, 2014 updated by: JOTEC GmbH

ASSIST - A Study in SurvIvors of Type B Aortic Dissection Undergoing Stenting

Cohort study according to national regulatory guidelines: Non-interventional, observational cohort study. Pair-matched comparison with patients chosen from historical series.

To evaluate the clinical and technical success as well as the safety and feasibility of the E-XL aortic stent used in complicated type B aortic dissection in addition to a classic stentgraft in a single procedure.

Study Population

Male and female patients with complicated type B aortic dissection involving the infra-diaphragmatic aorta

Description

The clinical records of the patients mus support the following criteria:

  • Age > 18 years
  • Type B dissection with expanding false lumen eligible for endovascular treatment which occured within 90 days prior to implantation
  • The endovascular treatment may be associated with a complementary surgical operation
  • The total diameter of the dissected aortic segment should not surpass 6cm, and have increased between 0.5 and 1cm within 1 month, prior to implantation
  • Visceral arteries involvement, i.e. perfusion of side branches via true or false lumen of type B dissection
  • Aortic kinking < 90°
  • The patient must be available for the appropriate follow-up times for the duration of the study
  • Informed consent from patient or authorized relative

The data of whose patients clinical records confirm one of the following conditions will not be considered in this study:

  • Patients with a contraindication as indicated in the instruction for use
  • Patients with chronic thrombocytopenia or ongoing anticoagulation
  • Patients with renal failure and/or creatinine >2.4mg/dl immediately before the intervention
  • Patients in whom the false lumen is completely thrombosed
  • Patients with ongoing infection
  • Patients with ongoing cancer
  • Patients who are enrolled in a clinical study
  • Aortic landing zone diameter over 40 mm
  • Potentially emboligenic iliac and aortic atheroma lesions
  • Associated pathology with life expectancy of less than 24 months
  • Unstable infectious syndrome
