Dynamic contrast-enhanced MRI analysis for prognosis of intracranial dissecting aneurysm with intramural haematoma after endovascular treatment: an observational registry study.

ABSTRACT:

Background and purpose

Intracranial dissecting aneurysm (IDA) with intramural haematoma (IMH) is an intractable cerebrovascular disease. The outcome of IDA with IMH after endovascular treatment varies across different individuals: some IMHs stop growing after endovascular treatment, while others continue to grow, even after embolisation of the parent artery. Currently, the mechanism for the continuous growth of IMH after endovascular treatment is still unclear. Continuous haemorrhage of the vasa vasorum in the IMH is considered to be associated with continuous enlargement of the IMH; however, this theory has not been proved by in vivo imaging.

Methods and analysis

This study will establish a prospective cohort of 80 patients who had an IDA with IMH and received endovascular
