Filter by:There are no endoluminal stent systems available on the Chinese market for the effective treatment of aortic arch lesions (involving aortic arch aneurysms, aortic coarctation, aortic pseudoaneurysms, aortic ulcers, and intermural hematomas), and therefore this study is intended to be a prospective, single-arm study.
A prospective, non-randomized trial of patients submitted to EVAR for aortoiliac aneursym using Endurant II (Medtronic) or Zenith (Cook).
AAA characteristics are traditionally measured with computed tomography angiography (CTA), however, three-dimensional ultrasound (3D US) is emerging as a novel imaging method for AAAs. With the use of a US contrast agent, the AAA thrombus can also be distinguished from the lumen on the 3D scans. This enables 3D visualization of the AAA and its thrombus without the need for harmful radiation and nephrotoxic contrast agents, as opposed to CTA. In in vitro measurements, 3D US has already been shown to have clinically acceptable error rate with AAA diameter and volume measurement. However, it is unclear whether this is also applicable to in vivo measurements. Therefore, the aim of this prospective study is to compare preoperative 3D US AAA characteristics as measured by 3D US with contrast enhancement (3D CEUS), 3D US without contrast enhancement (3D non-CEUS) and CTA.
The goal of this observational study is to perform an in vivo feasibility study using real time (3D) ultrasound based vector flow imaging in 10 AAA patients (5 with intraluminal thrombus and 5 without intraluminal thrombus). Furthermore, the investigators will investigate the added value of contrast microbubbles in these high framerate, plane wave ultrasound measurements. Included patients will undergo ultrasound scanning of their AAA, using multiple ultrasound sequences. Sequences will be tested with and without the addition of ultrasound contrast microbubbles.
The primary objective of this trial is to evaluate the safety and efficacy of the cerebral flow diverter in the endovascular treatment of wide-necked cerebral aneurysms
Superficial cerebral veins findings in assessment of brain swelling in patients with aneurysmal subarachnoid hemorrhage who underwent intravenenous DSA examinations
Cerebral swelling is a major complication following aneurysmal subarachnoid hemorrhage.This study is a retrospective cohort aimed to predict the extent of brain swelling. Cerebral venous assessment can identify the risk of brain swelling and improve surgical outcomes.
Thoracic aortic aneurysms (TAA) result from progressive dilatation of the thoracic aorta and confer a risk for aortic dissection or rupture, which is associated with significant morbidity and mortality. In the Netherlands there are an estimated 200.000 adults with TAA, and annually 600 deaths after aortic dissection or rupture. There are clear differences in the incidence of TAA between men and women, with a higher incidence in men. Little is known on possible differences in outcome between male and female patients with Thoracic Aortic Aneurysm (TAA). Aortic disease is thought to affect men more frequently than women, and aortic growth is different between men and women. Current data suggest that women are at an increased risk of both dying from aortic dissection and having aorta-related complications compared to men (1). The mechanisms for these male-female difference in TAA outcome remain, however, unclear. The timing of preventive surgery is now not different for men and women, but gender-based cut-off values for maximal aortic diameter based on differences in vessel wall composition might be needed.
The scope of this trial is the collection and analysis of the important safety outcomes in the real world, related to the use of the Tubridge flow diverter in the treatment of intracranial aneurysms.
In this project the investigators study the safety and efficacy of the pipeline embolization device with vantage technology in treatment of unruptured brain aneurysms
