Anatomical Feasibility of an Off-the-shelf Scalloped Stent-graft for Infrarenal Abdominal Aneurysm...

Aortic Aneurysm

In clinical practice a lot of EVAR cases are performed IFU for adverse neck anatomy(6) with acceptable short- and mid-term outcomes, but the long-term durability is currently an issue (7). Neck length shorter than 15 mm and angulation are two of. neck charteristics. that contribute more to define an "hostile neck" (8). The issue linked to the anatomical not feasibility of standard EVAR in patients not eligible for OR can be solved with custom made devices (CMD), but they were limited by high production costs and long time for creations (10-12 weeks)1. Nowadays no one off-the-shelf device aimed to overcome neck hostility in AAA is available on the market. The present study aims at evaluating the anatomical applicability of an off-the-shelf scalloped stent-graft to treat infrarenal AAA with a short and/or angulated neck.

Brain and Abdominal Aneurysm Study

Aneurysm

Aneurysmal subarachnoid hemorrhage (aSAH) is the most deadly kind of stroke. Each year, 40,000 Americans have SAH. Case-fatality approaches 60% and more than half of those who die do so before reaching the hospital. Most commonly, SAH results from rupture of an intracranial aneurysm. Screening high-risk individuals could identify those at greatest risk and decrease the devastating effect of SAH. Aortic Aneurysm also constitutes a major public health problem with high lethality. Current estimates are that ruptured aortic aneurysm kills 13,000 Americans each year. Screening efforts have effectively lowered mortality from aortic aneurysm rupture but a high proportion of those who die did not have a diagnosis of aortic aneurysm prior to rupture. The relationship between intracranial and aortic aneurysm has long been recognized, but poorly quantified. Recent genome-wide association studies (GWAS) provide a molecular biological evidence for a shared pathophysiology. The chromosome 9p21 locus confers increased risk for both intracranial aneurysms and aortic aneurysms. These GWAS data, along with linkage data for other susceptibility loci, indicate that individuals and families harboring one type of aneurysm may be at especially increased risk of the other. The rationale for this project is that opportunistic screening for abdominal aortic aneurysms (AAA) may be warranted in patients who present with aneurysmal subarachnoid hemorrhage. This study is meant to see if the yield of screening in this population is too low to justify its routine use. The investigators plan to systematically screen for AAA in all cases of aSAH presenting to MCH for treatment. If no individual out of 81 consecutively screened cases of aSAH has evidence of AAA, then the investigators can have strong confidence that there is a less than 5% chance of finding an AAA in the patient population.

Clinical Effectiveness of an Off-the-shelf Single REnal Scalloped sTent-graft for HOstile NEck Infrarenal...

Abdominal Aortic Aneurysm

The goal of this multicenter, observational cohort study is to evaluates the clinical effectiveness of a single-renal scallop custom-made stent-graft (TREO, Terumo Aortic, Sunrise, FL) to treat "hostile" AAA with mismatched renal arteries as actual standard of care in this Vascular Unit The main question it aims to answer are: if a dedicated devices could improve the results in the endovascular treatment of patients suffering to infrarenal abdominal aortic aneurism with a mismatched takeoff of the renal arteries. Participants responding to inclusion criteria will be treated as best clinical practice with a custom made device with a single scallop for the renal artery. The minimum follow-up requested, as standard clinical practice, was: 3-months, 12-18 months- and 5-years CTA; clinical and DUS examination at 6- and 12- and 36-months after the intervention and yearly thereafter. No comparison group was present.

Optimizing CO2 Injection Technique for EVAR

Abdominal Aortic AneurysmEndovascular Aortic Repair

Automated carbon dioxide (CO2) angiography is considered a safe diagnostic alternative to standard iodinated contrast medium (ICM) for endovascular aortic repair (EVAR) of abdominal aortic aneurysm (AAA), especially in patients with preoperative renal function impairment. Recent literature experiences describe the use of automated CO2 angiography in EVAR. One of the main issues of CO2 angiography is the inability to detect the origin of the lowest renal artery (proximal neck visualization) that was estimated up to 38%. In these experiences, the CO2 automated angiography is usually performed by a 5F pigtail catheter placed at renal arteries level. The aim of the study is to evaluate the efficacy of a new automated CO2 injection technique by a 5F introducer (single hole catheter) positioned at the distal level of the proximal neck in detecting both renal arteries in the first diagnostic and completion angiographies.

Comparison of a Full Automatic Software With Standard Methods of Vessels Analysis

Abdominal Aortic Aneurysm

The treatment of aortic aneurysms is today based on different indicators (diameters, lengths, angles, volumes of the arteries) measured on CT scan images. Several indicators are time consuming and complicatated to measure. They demand training and practice. Nurea is developing a software for automatic measurement of these indicators, PRAEVAorta® 2, to facilitate and assist the physician in his clinical routine. The purpose of this study is to compare the analysis realised by the software PRAEVAorta® 2 with the analysis realised by the healthcare professional on retrospective CT scan images. Contrasted and non-contrasted, pre-operation or post-operation CT scans from 50 patients will be analysed. The main objectif is to validate the accuracy of the software by demonstrating its adequacy to the standard method of analysis. The second objectives are the following: Evaluate the security of the software PRAEVAorta® 2 Evaluate the unanticipated risks related to the use of the software Validate the accessory PRAEVAorta® Web We make the following assumption : 90% of the patients show 90% of adequacy to the healthcare professional analysis

The purpose of this study is to evaluate the safety and performance of Cook's various Custom-Made Stent-graft Devices (CMD) used for endovascular treatment of the aorta and related diseases by collecting information on the real-world use of the devices. The study results will be used to support the continuation of the CMDs on the market. In addition, the study will support the manufacturers obligation for post market product surveillance as well as Cook's technology development.
