Active clinical trials for "Aneurysm"

Single center, open label, prospective, single-arm, first-in-human (FIH), pre-market clinical study with the objective of validating the safety and performance of the Suture-Tight™ Suture Delivery System in an EVAR procedure.

the goal of this clinical trail is to evaluate the efficiency and safety of intracranial aneurysm assistive software in the preoperative assessment. The trail is designed as retrospective, multicenter, controlled clinical trail. Collecting probable cases images retrospectively according to inclusion criteria and exclusion criteria strictly. Controlling bias strictly, to make sure the efficiency and safety of intracranial aneurysm assistive software is evaluated reliably and precisely. In our trail, software-assisstant planning controls against experienced-surgeon-independent planning，which aims to avoid bias effictively and eliminate non-test interferences.

Background: A sub-study of the AARDVARK (Aortic Aneurysmal Regression of Dilation: Value of ACE-Inhibition on RisK) trial indicated a statistically significant association between central blood pressure (BP) variability and abdominal aortic aneurysm (AAA) growth. The role of anti-hypertensive adherence has not been explored in the context of AAA growth. Objective: To confirm whether higher central BP variability is associated with higher AAA growth rates and to examine the effect of medication adherence on AAA growth rates in a prospective longitudinal cohort study. Methods: Up to 175 patients will be recruited over ten months from two sites with standardised quality control of AAA, BP and antihypertensive non-adherence measurement. Patients (>55 years), with AAAs ≥3cm in diameter (including AAA ≥5.5cm, not proceeding to surgery) will be recruited and undergo AAA ultrasound (US), BP (peripheral and central) and antihypertensive non-adherence measurements every four months (+/- one month) for 24 months. Ambulatory BP variability data will be collected. Data on medication adherence and beliefs around medications will be collected with validated questionnaires. Analysis: Primarily, the relationship between central diastolic BP visit-to-visit variability and AAA growth (estimated by multilevel modelling) based on US measurements and secondarily the relationship between central diastolic BP variability and time taken to reach the threshold for AAA repair (5.5 cm) or rupture.

The PLIANT II registry is undertaken to examine the real-world outcome after treatment of consecutive patients with uni- or bilateral aorto-iliac or iliac aneurysms using the E-liac Stent Graft System.

Despite the active development of surgical methods of treatment (endovascular embolization and microsurgical clipping) of cerebral aneurysms, determining the indications and method of surgical treatment of cerebral aneurysms still causes debate in many cases. To a greater extent, this concerns the treatment of unruptured aneurysms. While there are a number of randomized trials of surgical treatment of ruptured cerebral aneurysms, there is currently no published randomized trial comparing surgical clipping and endovascular embolization of unruptured aneurysms. The purpose of this study is to compare the safety and efficacy of microsurgical clipping and endovascular embolization of cerebral aneurysms (both ruptured and unruptured) in a prospective, randomized fashion.

Design A multi-centre pilot study investigating the acceptability and adherence of a prehabilitation on patients requiring abdominal aortic aneurysm repair. Setting 3 NHS Hospital Vascular Surgery Clinics in the UK. Imperial College Healthcare NHS Trust Cambridge University Hospitals NHS Trust Mid and South Essex NHS Trust Patient Population Patients referred to secondary/tertiary vascular clinic for the repair of asymptomatic infrarenal Aneurysm Intervention: Baseline (conducted face-to-face): After providing written informed consent, participants will be provided with information about the prehabilitation programme. The following data will also be collected: baseline demographic characteristics (including age, sex and ethnicity), body mass index (BMI), medical history (including time since diagnosis), current medication, aneurysm diameter, health-related quality of life (EQ-5D-5L and EQ-VAS), smoking status and psychological wellbeing (using the Hospital Anxiety and Depression Scale; HADS) and Frailty assessments( QMortality Index, Electronic Frailty Index, Rockall score). Participants will also complete a 6-minute walking test(6MWT).

Accurate preoperative identification of patients at high risk for adverse outcomes would be clinically advantageous, as it would allow enhanced resource preparation, better surgical decision-making, enhanced patient education and informed consent, and potentially even modification of certain modifiable risk factors. The aim of the Prediction of adverse events after microsurgery for intracranial unruptured aneurysms (PRAEMIUM) study is therefore to develop and externally validate a clinically applicable, robust ML-based prediction tool based on multicenter data from a range of international centers.

The ITACA study is a prospective, observational no profit registry enrolling patients with Acute Coronary Syndrome and angiographic evidence of coronary aneurysms and/or ectasia.

The aim of present study is to evaluate intraoperative, peri-operative, and post-operative results in patients treated by the ALTO stent graft (Endologix Inc. Irvine, Calif) for elective Abdominal Aortic Aneurysm repair in a multicentric consecutive experience.
