Brief Summary:
The purpose of this study is to compare endoluminal stent grafting with the GORE TAG device and Best Medical Therapy (BMT) to BMT alone in the treatment of acute uncomplicated type B aortic dissections.

Condition or disease Intervention/treatment Phase
Aortic Diseases Device: Gore TAG Endoprosthesis Other: Best Medical Therapy Not Applicable

Detailed Description:
Dissection of the aorta is a medical emergency requiring immediate surgery. Type B dissections are typically treated with surgery or endoluminal therapy when complications such as uncontrollable pain, organ ischemia, or aortic rupture are present. However, the treatment of patients with uncomplicated, acute type B dissections is controversial. Best medical therapy (BMT) is the standard of care in these cases since surgical repair offers no additional survival advantage. However, Endoluminal stent graft therapy with the GORE TAG Thoracic Endoprosthesis (GORE TAG device) may offer distinct advantages as an adjunct to medical therapy for uncomplicated acute type B dissection. The goal of endoluminal stent grafting is to cover the primary entry tear of the dissection to isolate the false lumen from blood flow and induce aortic remodeling.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 61 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Randomized European Study Comparing Endoluminal Stent Grafting and Best Medical Therapy (BMT) to BMT Alone in the Treatment of Acute Uncomplicated Type B Aortic Dissection
Study Start Date : August 2008
Actual Primary Completion Date : February 2012
Actual Study Completion Date : October 2013

Arm Intervention/treatment
Experimental: 1
Device: Gore TAG Endoprosthesis
Implant Gore TAG device with Best Medical therapy per physician discretion
Active Comparator: 2
BMT alone
Other: Best Medical Therapy
Best Medical therapy is regimen of antihypertensive medications used to maintain blood pressure below 125/80 mm/Hg throughout the entire follow-up period. Because BMT is assessed by blood pressure response to medication, specific medication regimens for each patient will differ. The typical regimen consists of 1 to 4 concomitant antihypertensive medications that may include angiotensin converting enzyme (ACE) inhibitors, alpha blockers, beta blockers, calcium channel blockers, diuretics, and/or vasodilators.

Primary Outcome Measures :
  1. Composite of Partial or No False Lumen Thrombosis, Aortic Rupture, and Aortic Dilatation [ Time Frame: 1 year ]

    Subjects with any of the following met this composite outcome:

    • partial/no false lumen thrombosis
    • aortic rupture
    • aortic dilatation
    • lack of 1 year imaging (no image, incomplete image missing primary endpoint measurements, unevaluable image)
