Official Title Radiotracer Imaging of Lower Extremity Skeletal Muscle Perfusion in Patients with Peripheral Arterial Disease

Purpose

The purpose of this study is to look at a new method to evaluate blood flow to the calves and feet. 

Peripheral Artery Disease (PAD) patient outcomes will be evaluated for up to 12 months after their revascularization procedure to assess how early changes in SPECT-derived foot perfusion relate to rates of diabetic wound healing and limb salvage. Outcomes will be specifically evaluated at 3, 6, 9, and 12 months after revascularization at the time of their follow-up clinic visits to the OSU Comprehensive Wound Center at OSU Hospital East. Primary outcomes of interest will be 1) changes in wound size and healing, 2) minor or major amputations of the lower extremity, and 3) any subsequent interventional procedures, such as balloon angioplasty, stenting, or surgical bypass.

Official Title IMPROVE-AD Trial: IMPRoving Outcomes in Vascular DisEase – Aortic Dissection

Purpose

The goal of this study is to figure out the best way to treat type aortic dissection. An aortic dissection is a tear in the wall of the aorta. The aorta is a big blood vessel that carries blood from your heart to the rest of your body. Individuals with this problem usually get medicine or a special repair procedure. This procedure is called thoracic endovascular aortic repair (TEVAR). TEVAR is a procedure where a metal tube (called a stent), is inserted in the damaged part of the aorta. The study is being done to figure out which treatment works better. The results of the study may help to prevent future problems with the aorta or other health issues. 

 

Could this study be right for you?

Inclusion:

• Age > 21 years
• Stanford type B aortic dissection not involving the aorta at or proximal to the innominate artery, without rupture and/or malperfusion (renal, mesenteric, or extremity)
• Acuity: within 48 hours – 6 weeks of index admission

Exclusion criteria:

• Ongoing systemic infection
• Pregnant or planning to become pregnant in the next 3 months
• Life expectancy related to non-aortic conditions < 2 years
• Prior surgery for aortic dissection

Age Range

Official Title AAA-SHAPE Pivotal Trial: Abdominal Aortic Aneurysm Sac Healing and Prevention of Expansion

Purpose

The purpose of this research is to determine if the IMPEDE-FX RapidFill System is safe and helps to shrink abdominal aortic aneurysm (AAA - a bulge or swelling due to weakening of the walls of the aorta, which is the main blood vessel that carries blood from your heart to other parts of your body) sacs after an endovascular stent graft (a fabric tube supported by metal wire stents that reinforces a weakened aorta) has been placed. The IMPEDE-FX RapidFill System used in this study is classified as investigational, which means it has not been approved by the Food and Drug Administration (FDA).

Could this study be right for you?

Inclusion:

• A candidate for elective EVAR of an infrarenal fusiform aortic aneurysm ≥5.5 cm in diameter in men and ≥ 5.0 cm in women 
• Thrombus burden (percentage of the AAA sac occupied by thrombus) <50%, based on pre-procedure CTA
• Maximum Lumen diameter within the AAA sac of ≥40mm
• The predicted minimum number of IMPEDE-FX RapidFill Implants for the subject is ≤200

Exclusion:

• An inability to provide informed consent
• Enrolled in another clinical study that could interfere with the outcomes being studied in this trial
• Unable or unwilling to comply with study follow-up requirements

Inclusion and Exclusion Criteria varies, please contact Study Coordinator for more information.
