Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The objective of INSTEAD is to compare long-term (5 years) outcomes of endograft prosthesis versus medical management in patients with dissection of the thoracic aorta.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Patients \> 18 years with type B aortic dissection were randomized to either thoracic aortic endoprosthesis (stent-grafting) or antihypertensive management (medical treatment). Only stable patients without spontaneous false lumen thrombosis 14 days after index dissection were considered eligible for study inclusion. Long-term outcome measures included all-cause mortality, aorta-specific mortality and a cluster endpoint (reflecting progression of disease, conversion and additional interventions); the analysis is based on 140 randomized cases followed for at least 5 years.
