简要总结

The purpose of this study is to assess the effects of a physician-modified endovascular graft (PMEG) for juxtarenal aortic aneurysms by collecting data on its performance. Participants in the study will undergo surgery to repair their juxtarenal aortic aneurysm using the PMEG device. After the surgery, participants will attend several follow-up visits to monitor their recovery and the device's effectiveness. These follow-up visits will take place at hospital discharge, then at 1 month, 6 months, 12 months, and once a year for up to 5 years after surgery.

详细描述

A juxtarenal aortic aneurysm is an aneurysm that occurs near the renal arteries, which bring blood to the kidneys. This research study will evaluate if the physician-modified endovascular graft (PMEG) is safe and effective in the treatment of juxtarenal aortic aneurysms. The PMEG device is an investigational device, which means it has not been approved by the FDA. The device is designed to create a pathway through the aneurysm for blood flow to the arteries, reducing the blood pressure that the aneurysm experiences. There are several types of endovascular devices depending on how big the aneurysm is, where the aneurysm is located in relation to the kidney, or other physical measurements of the blood vessels. The upper portion of the device, or stent graft, will include between one and four holes (fenestrations). The holes allow the device to be located above the renal arteries (the blood vessels that supply blood to the kidneys) without blocking the blood flow to them. Smaller grafts are then placed in the blood vessels to the kidneys, the intestines, and liver to be connected to the main aortic graft, allowing blood to flow to the organs.
