Evaluating Oral Peri-operative Acetylsalicylic Acid in Subjects Undergoing Endovascular Coiling-only...

Unruptured Cerebral Aneurysm

This trial is a is a prospective, randomized (1:1) placebo-controlled, clinical trial with blinded endpoint assessment of 440 participants with unruptured brain aneurysm planned for endovascular treatment using coiling-only approach (primary coiling or using balloon-assistance but not stenting) to test if oral acetylsalicylic acid (325 mg/ day for a total of 5 days) is superior placebo in preventing clinical and silent strokes. The primary outcome is a clinical or silent stroke at the time of discharge assessed by clinical examination and MRI brain. Participants will return to the clinic or be contacted by phone for the end of study procedures on Day 90 to collect functional outcome data.

Infliximab Therapy for Dolichoectactic Vertebrobasilar Aneurysms

AneurysmStroke2 more

Patients harboring dolichoectactic vertebrobasilar (DVB) aneurysms are at risk of suffering SAH, ischemic stroke, and/or brainstem compression and many patients are not offered invasive treatment due to the futility of existing surgical methods. Consequently, there is demand for development of medical therapy for DVB aneurysms

Clinical Outcomes and Radiation Safety After Endovascular Repair of Complex AAAs Using Fenestrated-...

Aortic AneurysmAbdominal1 more

The purpose of this study is to assess the clinical outcomes and radiation of the use of off-the-shelf and custom-made devices (CMDs) for the endovascular repair of juxtarenal, suprarenal, thoracoabdominal and arch aortic aneurysms in patients having appropriate anatomy. The study consists of three cohorts. The first 2 cohorts are the continuation of the current IDE study. The first cohort is aimed to assess the use of custom-made devices (CMDs) for the endovascular repair of juxtarenal, suprarenal and type IV thoracoabdominal aortic aneurysms in standard and high-risk patients having appropriate anatomy (Fenestrated-CMD cohort). The second cohort (Type I-III thoracoabdominal cohort) includes standard and high-risk patients with type I- III thoracoabdominal aneurysms that require the use of branched/fenestrated CMDs, or, in selected cases, the Zenith Thoracoabdominal Branch (Zenith® t-Branch™) device. Finally, the third cohort (the Arch cohort) will include 10 high-risk patients with aortic arch aneurysms treated by patient-specific stent-grafts with one to three inner branches or a scallop.

Clinical Trial for the Validation of AR Based Neuronavigation System

Brain NeoplasmsCerebral Aneurysm3 more

The goal of this clinical trial is to test augmented reality (AR) based neuronavigation system in surgeries for patients of brain neoplasm or cerebral vascular disease. The main questions it aims to answer are: • AR based neuronavigation system can achieve accuracy that is not inferior to conventional intraoperative navigation system. Participants will participate the study after informed consent. When participants undergo surgery for their brain tumor, we will set up 2 types of neuronavigation, conventional navigation system and developed AR based neuronavigation system. Surgeon will plan and conduct surgery based on only conventional navigation system, but 3D errors at several selected points between two types of navigation will be measured and analyzed.

Opioid Free Anesthesia-Analgesia Strategy and Surgical Stress in Elective Open Abdominal Aortic...

Elective Surgical ProceduresPostoperative Pain6 more

Open Abdominal Aortic Aneurysm (AAA) repair is a high-risk surgical procedure accompanied by intense endocrine and metabolic responses to surgical stress, with subsequent activation of the inflammatory cascade, cytokine and acute-phase protein release, and bone marrow activation. There is a proven correlation of surgical stress, which patients undergoing open AAA repair are subjected to, with patient outcome, morbidity/mortality, intensive care unit stay and overall length of stay. Modern general anesthetic techniques have been revised and rely on perioperative multimodal anesthetic and analgesic strategies for improved overall patient outcome. Based on this context of a multimodal anesthetic technique and having taken into consideration the international "opioid-crisis" epidemic, an Opioid Free Anesthesia-Analgesia (OFA-A) strategy started to emerge. It is based on the administration of a variety of anesthetic/analgesic agents with different mechanisms of action, including immunomodulating and anti-inflammatory effects. Our basic hypothesis is that the implementation of a perioperative multimodal OFA-A strategy, involving the administration of pregabalin, ketamine, dexmedetomidine, lidocaine, dexamethasone, dexketoprofen, paracetamol and magnesium sulphate, will lead to attenuation of surgical stress response compared to a conventional Opioid-Based Anesthesia-Analgesia (OBA-A) strategy. Furthermore, the anticipated attenuation of the inflammatory response, is pressumed to be associated with equal or improved analgesia, compared to a perioperative OBA-A technique.

Liposomal Bupivacaine/Bupivacaine in RS Blocks vs. Ropivacaine in RS Blocks And Catheters

Aortic AneurysmAbdominal3 more

The goal of this randomized clinical trial is to compare single shot rectus sheath blocks of liposomal bupivacaine/bupivacaine mixture to bilateral rectus sheath catheters infused with ropivacaine (standard of care at our facility) in patients undergoing vascular surgery with an open mid-abdominal laparotomy incision. This study will examine the difference in the highest, lowest, average, and current pain scores reported at the end of 24-48 postoperative hours using the brief pain inventory-short form (BPI-SF). Participants will be randomized to either receive a single dose of liposomal bupivacaine/bupivacaine mixture intraoperatively at the end of surgery through bilateral rectus sheath blocks (LB/B group) or to receive the standard of care ropivacaine intraoperatively at the end of surgery through bilateral rectus sheath blocks with the insertion of bilateral RS catheter for continuous ropivacaine infusion plus repeated daily boluses (Catheter group; standard care). They will be assessed for a difference in postoperative pain scores, opioid consumption, hospital and PACU length of stay, patient's satisfaction, and quality of recovery. Additionally, we will examine the resources consumed by each intervention, including the medication cost (ropivacaine vs. LB/bupivacaine mixture), block and catheter supply, hospital length of stay, and anesthesia billing time.
