Study summary

In this study patients will be observed, who receive a multi-branch stent graft tailored to the patients anatomy for the endovascular treatment of a thoracoabdominal aortic aneurysm Crawford type I, II, III, IV or V.

The objective of this study is to evaluate clinical and technical success as well as safety and feasibility of the multi-branch stent graft Systems used in endovascular treatment of thoracoabdominal aortic aneurysms that cannot be treated with commercially available devices. Primary endpoint of this study is the rate of patients with stable or decreasing aneurysm size at 12 months follow-up.

Read the detailed description

In this study patients will be observed, who receive a multi-branch stent graft tailored to the patient´s anatomy for the endovascular treatment of a thoracoabdominal aortic aneurysm Crawford type I, II, III, IV or V. Participating physicians will be asked to provide their observations collected during routine care for patients he/she had decided to treat with a multi-branch stent graft produced by JOTEC GmbH. Informed consent of the patients to allow the use of their clinical records for the purpose of this observational study will be obtained before data are being collected.

The period of data collection will be 36 months from the intervention for each patient. A risk based source data verification will be performed. CT angiograms will be evaluated by a CoreLab.

What researchers measure

Primary outcomes

  1. Rate of patients with stable or decreasing aneurysm size at 12 months follow-up (measured by CoreLab)

    Decreasing size: \>/= 5mm Increasing size: \</= 5mm compared to first post-operative CT angiogram

    Time frame: 12 months follow-up

Secondary outcomes

  1. Rate of all cause mortality

    Time frame: intra-op, post-op until 36 months follow-up

  2. Rate of patients with aneurysm rupture

    Time frame: post-op until 36 months follow-up

  3. Rate of patients with main adverse events (product-related, procedure-related, aneurysm-related)

    Time frame: post-op until 36 months follow-up

  4. Rate of interventions in peri-operative periods (all related interventions until index procedure)

    Time frame: intra-op

  5. Rate of reinterventions

    Time frame: post-op until 36 months follow-up

  6. Rate of patients with endoleaks type Ia, Ib, II, III, IV, V and of unknown origin

    Time frame: post-op until 36 months follow-up

  7. Rate of patients with multi-branch stent graft migration

    Time frame: post-op until 36 months follow-up

  8. Rate of patients with loss of device integrity

    Time frame: post-op until 36 months follow-up

  9. Rate of patients with primary / secondary patency of branch vessels

    Time frame: post-op until 36 months follow-up

  10. Rate of patients with stent graft infection

    Time frame: post-op until 36 months follow-up

  11. Rate of patients with primary / secondary technical success

    Time frame: post-op until 36 months follow-up

  12. Rate of patients with primary / secondary clinical success

    Time frame: post-op until 36 months follow-up

  13. Rate of patients with removal or failure to implant the multi-branch stent graft

    Time frame: intra-op, post-op until 36 months follow-up
