Abdominopelvic bleeding can occur due to numerous causes including for the vast majority, trauma, surgery complications and tumors. Interventional radiologists often exclude arterial acute hemorrhage using cyanoacrylate or a liquid embolic agent, but few prospective results have been published to assess their efficacy and safety. The historic and most studied liquid embolic agent to date is Onyx. Results in the treatment of acute peripheral non-neurologic hemorrhage have been detailed in a meta-analysis published in 2015. This systematic review found 19 articles presenting 131 patient cases and 150 lesions treated with Onyx from 2005 to August 2014. There were 11 case series and 8 case reports but no prospective trial. The most common presenting symptoms were of gastrointestinal (GI) origin (n = 51). Rebleeding of the baseline lesion occurred in 7/131 patients. No deaths resulting from complications of the embolic procedure were reported. One patient died of persistent hemoptysis after treatment with Onyx. No deaths were directly attributable to the use of Onyx. During a peripheral embolization procedure with available embolic agents other than SQUIDPERI, residual feedings or collateral vessels became gradually less visible to the operator due to the high radiopacity of the liquid. It was therefore essential to develop an embolization system with lower radiopacity, or with radiopacity that decreases over time. Additionally, depending on the angioarchitecture and flow characteristics, it is important to have an embolic agent with various viscosities. SQUIDPERI is a liquid embolic agent with various viscosities and radiopacities. It is indicated for the embolization of lesions in the peripheral vasculature but its use is poorly reported as of today. The purpose of this prospective non interventional multicenter study is to evaluate the safety and efficacy of SQUIDPERI for the treatment of abdominopelvic arterial acute bleeding or imminent risk of bleeding.
This study is a feasibility study to evaluate new technology to improve the MRI experience, with coils, sequences and software. Patients from the Principle Investigator's exam schedule are given the opportunity to participate in this study is their MRI exam is appropriate for the specific coil, sequence or software being evaluated. If they agree, they can receive their MRI exam with the new coil, sequence or software instead of the standard one.
Comparing 2 different anaesthetic methods during abdominal aortic aneurysm surgery. The patients will be followed up 30 days postoperative. Number of patients included will be 200. Perioperative details will be analyzed.
