Active clinical trials for "Aneurysm"

This is the first prospective study in Hong Kong that recruit patients with poor neurological status after intracranial aneurysm rupture in all seven public neurosurgical services in Hong Kong. This study assesses whether ultra-early aneurysm treatment improves outcomes in patients with poor neurological status after intracranial aneurysm rupture in Hong Kong. These data are essential to understand the impact of the disease and for future service development in Hong Kong.

Fenestrated endovascular repair (FEVAR) is nowadays a recognized option to treat juxtarenal, pararenal or suprarenal abdominal aortic aneurysms in patients at high risk for conventional repair. The technique consists in deploying a custom-made stent-graft (SG) inside the patient aorta. Part of the customization involves cauterizing a hole in SG fabric and reinforcing it with a Nitinol stent ring, thereby creating a fenestration for each corresponding collateral artery. For this reason, preoperative planning is crucial to determine adequate positions of fenestrations, in order to obtain perfect alignment with the collateral arteries of the patient. Inadequate positioning may result in failure to catheterize a collateral artery and subsequent organ damage, increased catheterizing time, increased irradiation dose, endoleaks… The current process of fenestrations positioning for fenestrated anacondaTM SG involves: (i) anatomical measurements on patient preoperative CT-scan by case planners using dedicated sizing software; (ii) designing an initial custom device scheme with its positioned fenestrations, created by engineers with CAD software using the above cited measurements and (iii) validation of fenestrations position by in vitro testing using a SG prototype deployed inside a transparent anatomy model (3D-printed model of patient aorta and collateral arteries). The main limitations of this process are the costs and long SG delivery time.

The incidence of delirium following open abdominal aortic aneurysm (AAA) surgery is significant, with incidence rates ranging from 12 to 33%. The occurrence of delirium on the surgical ward after intensive care unit (ICU) dismissal in AAA patients remains unclear. Differences in outcomes between a delirium on the ICU and a delirium on the surgical ward have not been previously investigated. Delirium is a frequent complication in patients who underwent open AAA surgery. This study demonstrated that patients on the surgical ward remain at risk for developing a delirium after ICU dismissal. Physicians should therefore maintain a high level of awareness for delirium in AAA patients who return to the surgical ward after ICU dismissal. This simultaneously emphasises the necessity of delirium preventive measures and early recognition on the surgical ward in order to improve clinical outcomes.

In situ fenestration (ISF) could represent an alternative in the treatment of aorto-iliac disease when usual techniques are not available. The aim of this study was to present the results of ISF in aorto-iliac disease. Data will retrospectively be analyzed. Inclusion criteria will be: a surgical abdominal aortic aneurysm (AAA) with an unsuitable anatomy for a standard endograft, aorto-iliac occlusion with narrow distal aorta (<14mm). Technically, after placement of the endograft, a transjugular intrahepatic access set was used to perform ISF. The hole was secondary enlarged using a cutting or non-compliant balloon. Finally, a kissing stent was performed to the aorto- uni-iliac into a bifurcated endograft.

The aim of our study is to evaluate the incidence of post-operative thrombotic complications after abdominal aortic aneurysm surgery in the context of atherosclerosis or infectious aneurysm and its links with preoperative inflammation and hemostasis.

A retrospective review was performed for consecutive patients (from 2019 to 2021) who underwent salvage surgeries following failed endovascular therapies for splanchnic artery aneurysms in a tertiary referral center. Salvage operations include total aneurysmectomy with vascular reconstruction and partial aneurysmectomy with directly closing bleeders from the intraluminal space of the aneurysms.

The aim was to evaluate early and medium-term outcomes of single and double fenestrated physician-modified endovascular grafts (PMEGs) for endovascular aortic arch degenerative aneursym repair. The evolution of stent-graft technology recently has meant the development of custom-made branched stent-grafts to achieve total endovascular aortic arch repair for high-risks patients. The disadvantages of custom-made include manufacture and deliver times for urgent cases and the associated high costs. Unfortunately there is also a high rate of embolization associated with this approach probably related to the complexity of deploying a multi-branched unibody stent-graft. A further alternative is physician modified endografts (PMEGs) for zone 0 TEVAR involving the deployment of a conventional stent-graft device ex-vivo, fashioning of customized fenestrations (for supra aortic trunk) and re-constrainment into the delivery system. The authors have previously shown the feasability in vitro and they have reported their experience for arch aortic lesion. The aim of this study is to evaluate the outcomes for aortic arch degenerative aneursym repair which is the most risky procedure

The purpose of the registry is to evaluate the peri-operative, short-, and mid- outcomes of endovascular treatment of thoracoabdominal aneurysms with multibranched endografts via total transfemoral approach for visceral vessels cannulation using steerable sheaths

A prospective non-interventional study aimed to evaluate the immediate and long-term outcomes in patients with left ventricular aneurysm after transmural myocardial infarction. A registry of patients with transmural myocardial infarction admitted to the Emergency Department of Cardiology will be created. The registry will include all consecutive hospitalized patients from from January 1, 2021 to December 31, 2021 who meet the inclusion criteria Based on this registry, patients will be divided into groups : patients with left ventricular aneurysm and patients without aneurysm, patients with left ventricular thrombosis and patients without thrombosis. Patients will be contacted in 3 and 12 months. Surviving patients will be invited to appointment for an ECG, echocardiography and survey. The cardiovascular events during this period will be recorded. The factors determining the prognosis of patients and their concomitant diseases, immediate and long-term prognoses, therapeutic measures and drug therapy at the hospital and outpatient stages, and patients ' adherence to therapy will be analyzed.

To investigate the influence of limb remote ischemic preconditioning (LRIP) on mortality, hospitalization costs and quality of life in patients undergoing open infrarenal abdominal aortic aneurysm (AAA) repair.
