Active clinical trials for "Aortic Aneurysm"

Evaluate the safety and effectiveness of endovascular repair with the LeMaitre TAArget thoracic stent graft as an alternative to open surgical repair.

The purpose of this study is to determine whether immunonutrition and pre operative nutrition can reduce lenght of respirator support, lenght of stay in the ICU and incidence of post operative infections

Objectives. To study the feasibility of an expertise-based randomized controlled trial (RCT) testing the role of traditional surgery (OPEN) versus endovascular repair (EVAR) for abdominal aortic aneurysms (AAA). Study design. We will conduct an expertise-based RCT comparing OPEN to EVAR of non-urgent abdominal aortic aneurysms in patients referred to vascular surgeons practicing at Hamilton Health Sciences, to determine the rate of death and other complications. Quality of life and status at 6 months will also be recorded. The ultimate goal is to determine the feasibility of conducting a pragmatic expertise-based RCT and to inform a future larger study at a national level.

Comparative study on efficacy of haemostatic therapy guided either by standard laboratory coagulation parameters or point-of-care testing in patients undergoing vascular surgical procedures. We investigate the amount of perioperative bleeding and the number of blood product used. Inclusion criteria Patients scheduled for elective and acute open aorta surgery or undergoing acute aorta surgery with minimally invasive techniques and were provided treatment in the operating theatre and/or ICU attached to perioperative care, they must be at least 18 years of age and written informed consent was obtained from the patient or his/her legal representative. Randomisation technique Patients will be randomly assigned to each of two treatment groups using sealed envelopes. In group 1 (G1) haemostasis strategy guided by conventional coagulation tests, while in group 2 (G2) transfusion algorithms guided by point-of-care (POC) tests will be carried out. Sampling techniques and measurements For assessment of monitored parameters shall be used arterial or venous blood depending on the catheter placed preoperatively. In case of the above mentioned vascular surgical procedures, all patients will receive arterial cannula routinely, and, depending on the extension of procedure, as appropriate, a central venous catheter will be inserted as well. Sampling in the patient groups shall be performed as follows: pre- and postoperative evaluation of standard laboratory parameters in all patients evaluation of standard laboratory parameters and arterial Astrup test during and after surgery in group 1, if the blood loss volume reaches 1,5 ml/kg/minute during 20 minutes in case of elective surgery: thromboelastometry and arterial Astrup test during and after surgery in group 2 if the blood loss volume reaches 1,5 ml/kg/minute during 20 minutes in case of acute surgery: thromboelastometry and arterial Astrup test before, during and after surgery in group 2 in case of positive anamnesis, preoperative platelet aggregation test in both groups Besides the above samplings, routine lab tests (blood gas, blood count, sodium (Na), potassium (K), parameters of renal and liver function, clotting and inflammation, lactic acid, blood sugar) will be performed every day as usual during intensive therapy.

SASH Trial is a multicenter, prospective, open and randomized 1:1 study. The aim of this study is to evaluate the efficacy of TDM-621(Three-D Matrix- 621) (PuraStat®) on hemostasis of ascending aortic surgery. The TDM-621 is a topic hemostatic product. When in contact with blood it allowed to cover the sutures improving the hemostasis. The hypothesis is that the use of TDM-621 may reduce bleeding and the need for blood transfusion of patients undergoing ascending aortic surgeries. It will include 200 consecutive patients randomized to receive TDM-621 or regular procedure, performed in 5 different centers.

This is a Prospective, Open-label, Multicenter, and Non-randomized Clinical Study. The main purpose of this study is to establish the efficacy and safety of a medical device system, SETA LATECBA Stent Graft, intended for the treatment of EVAR of pararenal AAA (patients with complex anatomy, not eligible for other surgical procedure).Other objective is to evaluate the technical performance of the device SETA LATECBA Stent Graft.

The investigators compare different endovascular techniques as an alternative to surgical reconstruction to repair JAAS regarding ; success rates, 30-day mortality,endoleak events secondary intervention rates

The ETAP study aim to assess the effect of the addition of an ultrasound-guided transversus abdominis plane (TAP) block to a multimodal intravenous analgesia protocol on the postoperative pain control in open surgical repair of abdominal aortic aneurysm. The ETAP study is a single-center open-label randomized controlled trial. Half of patients included will receive the association of TAP block and multimodal intravenous analgesia, and the other half will receive the multimodal intravenous analgesia alone. The multimodal intravenous analgesia includes intravenous paracetamol and intravenous patient-controlled analgesia with morphine.

The purpose of this study is to evaluate the safety of deploying and implanting the Altura Abdominal Aortic Aneurysm (AAA) Endograft in the treatment of abdominal aortic aneurysms in subjects who are candidates for open surgical aneurysm repair.

The purpose of the study is to assess the performance and safety of the InterGard Synergy vascular graft.
