Filter by:The goal of this clinical trail is to compare the difference between transradial access (TRA) and transfemoral access(TFA) for ruptured intracranial aneurysms embolization. The main question it aims to answer is: whether is TRA not inferior to TFA？ In the experimental group, the transradial access (TRA) was used, which was to puncture the radial artery and insert a radial sheath to establish a surgical pathway for embolization of the aneurysm; In the control group, transfemoral access (TFA) was used to embolize the aneurysms, which was to puncture the femoral artery and insert the femoral sheath to establish a surgical pathway for embolizing the aneurysms.The two groups of patients received an oral loading dose of aspirin (300mg) plus clopidogrel (300mg) on the day of surgery, while patients who were unable to take orally were given nasal feeding. During the operation, systemic heparinization was performed with a starting dose of 75U/kg intravenous injection, and the injection was halved every 1h until 1000U. After the operation, protamine neutralizing heparin (1mg protamine neutralizing 100U heparin) was used.
This project aims to evaluate the efficacy and safety of the combination of glucocorticoids with tocilizumab or tofacitinib, compared to the traditional combination of glucocorticoids with cyclophosphamide in the treatment of vascular Behçet's syndrome.
To establish the safety and effectiveness of the SEAL™ Saccular Endovascular Aneurysm Lattice system for the treatment of saccular intracranial aneurysms. The data from this study will be used to support a premarket approval (PMA) submission.
An abdominal aortic aneurysm is a condition where the major artery in the abdomen becomes larger than usual. Over time, as it continues to grow, the wall of the artery weakens and there is a risk that the artery can burst causing internal bleeding and death. Aortic aneurysms are fixed when they reach a certain size to prevent that outcome. The surgery to fix them is a major, high-risk surgery that is associated with a lot of complications and a slow recovery back to normal. The time between diagnosis and surgery is called the pre-operative period and is a key time to optimize a patient's health in order to ensure the best possible outcomes following surgery. This study will look at whether a multidisciplinary pre-operative program that involves exercise training, nutritional advice and supplementation, and psychosocial support will reduce complications following surgery. This program should decrease complications and speed up a patient's recovery back to normal after surgery. It is also a way for patients to take ownership of their disease and play an active role in their health care journey. The benefits from this program will go beyond the pre-operative time frame, as the habits and knowledge gained will improve their health over their lifetime. This study will also assess the economic impact and cost of a program like this.
The aim of the study is to investigate if iv iron formulation improve recovery after surgery with blood loss. Post-operative anaemia is a common debilitating condition after major surgery due to a combination of preoperative iron deficiency anaemia (IDA) and per-operative blood loss. Median blood loss following hepatopancreatobiliary (HPB) and complex aortic surgery typically range between 500-1000 ml. Bioavailability of iron may be a rate limiting factor in erythropoiesis in anaemia secondary to blood loss. For the IRIS trial, it is hypothesized that intravenously (iv) administered Ferric Carboxymaltose after a per-operative blood loss of 400-4000 ml, improves post-operative recovery and reduces the RBC transfusion. Patients scheduled for elective HPB surgery or complex aortic surgery will be screened for eligibility and recruited into the study. By the end of the surgical procedure, if blood loss is estimated to 400-4000 ml, the patient is randomized 1:1 to iv 1000 mg Ferric Carboxymaltose or placebo. The primary endpoint is a composite of death, number of RBC transfusions, post-operative severe anemia (Hb <80 g/L) and FACT-An Quality of life (QoL) five weeks after surgery, assessed by win ratio. The trial will also examine effects on; a) levels of Hb; b) markers of erythropoiesis and iron bioavailability; c) post-operative complications; d) post-operative recovery; e) performance status; f) subgroups based on type of surgery and degree of anemia and iron deficiency; g) re-admissions; h) long term outcome based on patient medical records and i) how post-operative recovery differs between those with low (<400 ml), high (400-4000 ml) and very high (>4000 ml) per-operative blood loss. Recruitment will continue until 338 patients are randomized or 304 have completed the five week follow up The coordinating center of the trial is the Department of Surgery at Uppsala University Hospital. Participating sites are also Linköping University Hospital and Lund University Hospital, all in Sweden. Other sites may be added.
Aortic stiffness is an important imaging biomarker of vascular aging. The ascending aorta is the most elastic segment, and it is excluded by reference non-invasive method carotid to femoral pulse wave velocity (PWV). We propose to use laser-doppler vibrometry (LDV) to record superficial vibrations generated by cardiac activity and arterial pulses for measuring heart carotid PWV, a surrogate for ascending aorta. The trial aims to demonstrate the equivalence between heart-carotid PWV made by laser-doppler vibrometry (LDV) with the reference MRI measurement (4D-FLOW MRI). As secondary objectives, A) we aim to assess the reproducibility of LDV, compared with MRI, B) show that aortic stiffness measured by LDV fulfils international recommendations, C) to study the association between PWV and age or other cardiovascular risk factors, D) assess the acceptability of the measurement. For this, we include 100 consecutive patients, 50 women, 50 men, scheduled for clinically indicated thoracic aorta MRI.
This is a preliminary randomised controlled trial comparing the use of pre-operative 3D models to select an intrasaccular flow disruptor for endovascular aneurysm cure.
Rationale: Aortic diameter is currently used as a gold standard in international guidelines for prediction of aorta pathology (aortic aneurysm and aortic dissection). However, aortic diameter has proven to be insufficiently accurate for making decisions about well-timed preventive interventions. The LANDMARC study will take place in line with the FIBAA-bank ('Correlatie tussen cardiovasculaire FIBroseringsgraad en Aorta elongatie, dilatatie en Atria dilatatie (FIBAA-bank): een biobank & databank onderzoek met focus op aorta en atria' (METC-number 2022-3164)), and aims to reveal the undiscovered relationship between WSS (wall shear stress) values and aortic strain. In combination with data from the FIBAA-bank, the LANDMARC study will provide more accurate information for future risk stratification models for cardiovascular pathology (with focus on aortic disease). Objectives: Primary objective: indication of the association between WSS (peak WSS and WSS gradient) (through 4D-flow MR and CT) and aortic strain. Secondary objective: indication of the association between (hemo)dynamic processes within the body (aortic elongation/aortic strain) and (patho-)physiological changes (degree of cardiovascular tissue fibrosis).

This exploratory trial aims to evaluate the feasibility, safety and effectiveness of rivaroxaban compared to warfarin for thromboprophylaxis in children with giant coronary artery aneurysms after Kawasaki disease
