The primary intent of the study is to assess safety and preliminary effectiveness of the device acutely (i.e., treatment success and technical success), at 30 days (i.e., the rate of major adverse events (MAE)) and at 3 months, 6 months, 12 months, and annually to 5 years (i.e., the proportion of treatment group subjects that achieve and maintain treatment success).\n\nAdditionally, this study will assess the degree of patient frailty before and after the aneurysm repair, as well as the association between the preoperative baseline frailty and clinical outcomes detailed above. This will help improve subject selection in identification of high risk patients who would not only suffer poor clinical outcomes, but also experience decline in their functional status.","Device Description\n\nTwo types of commercially approved thoracic aortic stent-grafts will be modified under the aegis of a physician-sponsored IDE protocol (G200159). The Cook (Bloomington, IN) Zenith Alpha proximal tapered mainbody thoracic stent-grafts and the Cook Zenith TX2 proximal tapered mainbody will be modified to form the fenestrated\u002Fbranched aortic components. The Alpha thoracic stent-grafts are constructed of woven polyester graft sewn to discrete rows of self-expanding Nitinol Z stents. The most proximal sealing stent is located internally with fixation barbs that protrude through the graft material. The second proximal stent is straight, and the third stent is tapered by 4mm in diameter.\n\nThe diameter of the TX2 proximal tapered stent-grafts will range from 32mm to 42mm, depending on the size of the aorta at the proximal seal zone. The lengths will range from 154 to 210mm. The TX2 thoracic stent-grafts are constructed with woven polyester graft sewn to discrete rows of self-expanding stainless steel Z stents. The most proximal seal stent is sewn inside the polyester fabric. The third stent is tapered by either 4mm or 8mm in diameter.\n\nThe modification design will be planned using a 3-D multiplanar reconstruction analysis of the CT angiography. Proximal seal zone will be chosen at 2cm disease free parallel aortic walls. Target vessel position will be determined by the longitudinal distance between the proximal extent of the seal zone to the middle of the vessel orifice, as well as radial clock position. Based on these measurements, patient specific modification map will be constructed.\n\nThe modification will be designed to incorporate visceral and renal branches, utilizing a various combinations of fenestrations and branch cuffs. The choice between fenestrations and branch cuffs will be made based on the aortic size and angulation at the level of the target branches. For example, when the target branches are within the seal zone, fenestrations will be chosen. Conversely, branch cuffs will be incorporated onto the mainbody if the aorta at the level of the target branches is aneurysmal, or angulated where precise three dimensional position of the target branch, hence fenestration, along the implanted stent graft is difficult to predict.\n\nModification Technique\n\nModification will be performed on the day of the operation using strict sterile technique. Tapered low profile Cook Zenith Alpha proximal component thoracic stent grafts will be unsheathed. One of the trigger wires is retrieved from the inner cannula of the delivery system, to be used as a diameter constraining wire. This wire is rerouted posteriorly through and through the fabric of the stent graft using a long 22-gauge needle.\n\nFenestrations at planned locations will be created using an ophthalmic cautery, and reinforced with a double layer of Amplatz Gooseneck Snare (Medtronic, Minneapolis, MN) wires made up of braided Nitinol. The wires will be secured around the fenestration by tightly spaced 5-0 Ethibond (Ethicon, Somerville, NJ) locking sutures. Additional radiopaque markers will be sutured around each fenestration. When necessary, directional branch cuffs will be created by fashioning 8mm or 6mm Viabahn self expanding covered stents (Gore \\& Associates, Flagstaff, AZ) into 2cm long side branch cuffs. The branch cuffs will be sutured to the oval fenestration created on the aortic stent grafts by running 5-0 Goretex sutures. Radiopaque markers will be sutured around the entrance and exit of each branch cuff.\n\nPrior to resheathing, the posterior aspect of Z-stents are constrained using loops of prolene sutures as diameter reducing ties. Proximal fixation barbs will be removed using a wire cutter. Fenestrations and branches designed to be catheterized from the brachial approach will be pre-wired with 0.014 inch guidewires. The modified stent graft will be resheathed using 2-0 Silk ties and Umbilical tapes.",[19,20,21,22],"Thoracoabdominal Aortic Aneurysm","Thoracoabdominal; Aortic, Aneurysm, Dissecting","Pararenal Aneurysm","Frailty Syndrome",[],"INTERVENTIONAL","TREATMENT",[27],"NA",{"count":29,"type":30},100,"ESTIMATED",[32],{"type":33,"name":34,"description":35,"armGroupLabels":36,"otherNames":38},"DEVICE","Physician Modified Endografts","Modification procedure Description of modified device is detailed in Section 3.5 of IDE.
