Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Patients with a chronic subdural hematoma (cSDH), that is, a blood accumulation between two meninges developing over a long period of time, often have recurrent bleedings after an initial operation. The study aims to show that additional surgery reduces the risk of recurrent bleeding.

The additional procedure aims to block small blood vessels in the skull with tiny plastic particles. The small blood vessels are embolized using X-rays and a contrast medium and a fine tube that is inserted into the diseased vessels of the head via the groin.

Patients of full age who have undergone burr hole trepanation as a first operation, i.e. a blood drain through a hole in the cranial cavity, can participate in the study. Participating patients are randomly assigned to a control group with treatment according to clinical routine or a treatment group with an additional occlusion of the blood vessels in the skull. In addition, patients can consent to a genetic test to determine the relationship between a coagulation factor and the risk of recurrence of the hematoma. In order to record the test results, check-up examinations are carried out after one and three months.

Surgery plus endovascular MMA embolization

Group Type EXPERIMENTAL

Surgery plus endovascular MMA embolization

Intervention Type PROCEDURE

A micro catheter is inserted transfemorally into the branches of the middle meningeal artery (MMA) in a minimally invasive manner and the periphery is occluded using polyvinyl alcohol (PVA) particles to prevent future bleeding. If the desired catheter position cannot be achieved due to the anatomical conditions, a more proximal closure of the MMA using Onyx® or micro-electric coils is performed. Embolization of the MMA by PVA particles with sizes between 40-300 µm is preferred over embolization by coils and Onyx®, since the capillary network of the dura is entirely blocked when using particles. In order to identify the vessels to be closed, a digital subtraction angiography (DSA) is performed.
