NCT ID: NCT03439423 Recruiting - Clinical trials for Abdominal Aortic Aneurism

Control Post Endovascular Treatment of Aortic Aneurisms Through Magnetic Resonance and Ultrasound (SAFEVAR)

Start date: March 9, 2016
Phase: N/A
Study type: Observational

The aims of this study are to verify non-inferiority of magnetic resonance (MR) without contrast agent associated to color-Doppler ultrasound for the diagnosis of endoleaks after endovascular aortic repair (EVAR), to evaluate both the economical and biological cost-effectiveness of such diagnostic algorithm as an alternative to computed tomography (CT) with contrast agent, and to analyze its impact on both patients work-flow and infrastructure logistics

NCT ID: NCT03426839 Active, not recruiting - Clinical trials for Perioperative/Postoperative Complications

Haemostasis Management of Abdominal Aortic Procedures

Start date: May 2016
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT03327688 Not yet recruiting - Clinical trials for Deep Vein Thrombosis

Point-of-care Ultrasound in Finland

Start date: October 2017
Phase: N/A
Study type: Interventional

This study has two aims. 1. Deep venous thrombosis (DVT) is a common suspected medical condition. If it cannot be excluded clinically and using D-dimer, ultrasound examination is required. An option for traditional radiologist-performed ultrasound is a 2-point compression ultrasound (2-CUS). The safety of this technique is proven. However there does not exist any data on costs comparing traditional and 2-CUS pathways in primary health care. This study will evaluate the total cost of both pathways by conducting a cost-minimization analysis. It will also study the effect of a simple ultrasound education on the referrals to hospital due to suspected DVT. Hypothesis 1: Short education in ultrasound will reduce significantly referrals to hospital and save resources. 2. Length of stay (LOS) in emergency department (ED) is related to increased mortality, morbidity, prolonged hospital stay and probably patient satisfaction. LOS of patients with a point-of-care ultrasound (POCUS) performed by an emergency physician (EP) will be compared to those that have a radiology performed ultrasound examination. Further examination and accuracy of POCUS will be noted. Hypothesis 2: POCUS can shorten LOS significantly in selected clinical conditions

NCT ID: NCT01834092 Recruiting - Surgery Clinical Trials

Study of the Glycocalyx in Abdominal Aortic Aneurysm

Start date: April 2013
Phase: N/A
Study type: Interventional

The investigators want to measure the degradation of the endothelial glycocalyx before and after clamping the aorta, in patients operated for a abdominal aortic aneurism.
