Lymphatic Injury Visualization in Vascular Surgery

This study aims to assess a simple intervention: Visualization of lymphatic injury + treatment (in case of detection). This will generate data on the incidence of intraoperative lymphatic injury and the effect of treatment. This data will then hopefully enable a multi-center RCT to generate high level evidence on this matter.

EUS-guided Embolization of the Visceral Artery Aneurysm

Visceral Artery Aneurysm (VAA) refers to a localized or diffuse dilation or bulging of the arterial wall in the arteries supplying the gastrointestinal tract, liver, spleen, and pancreas (celiac trunk, superior mesenteric artery, inferior mesenteric artery, and their branches), caused by various pathological conditions or injuries. Among these, splenic artery aneurysms (60%) and hepatic artery aneurysms (20%) are the most common. Similar to cerebral aneurysms and aortic aneurysms, visceral artery aneurysms are a serious vascular disease that threatens human life, with an incidence of 0.2% to 2.0% in the population, second only to abdominal aortic aneurysms and iliac artery aneurysms. The main etiologies include atherosclerosis, degeneration of the arterial media, infection, fibromuscular dysplasia, congenital abnormalities, trauma, and arteritis. The incidence of visceral artery aneurysms ranges from 0.01% to 0.20%. Although the incidence is relatively low, the rupture rate can be as high as 25%, often leading to hemorrhagic shock or even death. The treatment of VAA primarily includes open surgical procedures such as aneurysm resection and vascular reconstruction, as well as endovascular interventions such as aneurysm embolization and covered stent graft placement. Endovascular embolization is the first-line treatment for VAA. This procedure involves puncturing the femoral artery using the Seldinger technique, advancing a microcatheter near the affected vessel, injecting high-pressure iodinated contrast to visualize the lesion, and then superselecting into the aneurysm or adjacent vessels to embolize the aneurysm or its outflow tract using coils or tissue adhesive. However, X-ray-guided treatment is relatively expensive and involves complex steps. Additionally, for small aneurysms, aneurysms with narrow necks, tortuous vessels, or patients allergic to iodine, surgical resection of VAA may be the only option. Surgical procedures are associated with significant trauma, high costs, and multiple complications. Endoscopic Ultrasound (EUS) involves an ultrasound probe attached to the tip of an endoscope, allowing imaging and fine-needle aspiration of the pancreas, gastrointestinal tract, posterior mediastinum, and retroperitoneum. Linear EUS can also identify abdominal vessels and blood flow signals via color Doppler. Therefore, after localizing the VAA with EUS, a fine-needle aspiration needle is advanced into the aneurysm. Through the needle tract, a 0.035-inch or 0.018-inch coil is deployed, and tissue adhesive is injected under direct visualization until the aneurysm is completely embolized (Figure 1). This technique has been reported in international literature.

Determining Postoperative Recovery and the Impact of Adverse Events in Neurosurgery Based on Self-reported, App-based Longitudinal Assessment

Analyzing the impact of surgery and adverse events (AEs) on patients' well-being is of paramount importance as it provides essential information for benefit-risk assessment. Current methods in outcome research are static, resource-intensive and subject to missing-data issues. Moreover, AEs are inconsistently reported using various grading systems that usually do not account for patients' subjective well-being. These are severe drawbacks for outcome research as it hinders monitoring, comparison, and improvement of treatment quality. The increasing use of smartphones offers unprecedented opportunities for data collection. The investigators developed a free smartphone application to assess fluctuations of patients' well-being as a result of surgical treatment and possible AEs. The application is installed on each patient's smartphone and collects standardized data at defined timepoints before and after surgery (well-being, AE description and severity). By acquiring longitudinal patient-reported outcome before and after neurosurgical interventions, the investigators aim to determine the regular postoperative course for specific surgical procedures, as well as any deviation thereof, depending on the occurrence and severity of AEs. The investigators will evaluate the validity of existing AE classifications and, if necessary, propose a new patient-centered scheme. The investigators hope that this will result in an increase in standardized reporting of patient outcome, and ultimately allow for evidence-based patient information and decision-making.

Standardized Long Term Follow-up of Patients After Endovascular Embolization of a Brain Aneurysm

The time-frame and the follow-up elements after embolization of brain aneurysm are not standardized. Therefore, few reliable follow-up data are available for these patients. This study aims at collecting standardized long term data for these patients, in order to assess the occurence of aneurysm recanalization and particularly those requiring another intervention on the aneurysm.

Infliximab Therapy for Dolichoectactic Vertebrobasilar Aneurysms

Patients harboring dolichoectactic vertebrobasilar (DVB) aneurysms are at risk of suffering SAH, ischemic stroke, and/or brainstem compression and many patients are not offered invasive treatment due to the futility of existing surgical methods. Consequently, there is demand for development of medical therapy for DVB aneurysms

Arch Size Study for Anatomical Variations

The aortic arch with a common origin of the innominate and left carotid artery (CILCA) prevalence in the general population is 13.6%. Its reputation as a benign anatomical variant has been ultimately shattered by further studies that identified the CILCA arch as a potential marker for thoracic aortic disease (TAD) The aim of this work is to report the CT anatomical characteristics of the aortic arch in subjects with or without aneurysms requiring treatment, in 5 major European cardiovascular centers.

Subjects were evaluated by mRS preoperatively, at the time of device implantation, at the time of discharge from the hospital, at 1 month (±7 days) postoperatively, at 6 months (±30 days) postoperatively, and at 12 months (±60 days) postoperatively; subjects would underwent DSA imaging at surgery and at 6 months (±30 days) postoperatively, and MRA or DSA imaging at 12 months (±60 days) postoperatively. Unplanned follow-up of the subjects would performed when necessary, and data would be recorded to evaluate the safety and efficacy of intracranial artery stent for stent-assisted coiling embolisation for the treatment of intracranial aneurysms.
