Interventional Neuroradiology and Stroke

The Department of Interventional Neuroradiology at the USZ covers the entire spectrum of neurovascular diseases. Our highly specialized and internationally renowned experts in the field of interventional neuroradiology perform dedicated diagnostic imaging, consultation and minimally invasive procedures.

Our team will carry out thorough diagnostic examinations for patients diagnosed with an intracranial vascular change, e.g. an aneurysm, an arterio-venous malformation, or suffering from a pulse-synchronous tinnitus. Based on the acquired data, we offer individualized advice to each patient and decide on further treatment steps. We are part of the USZ neurovascular treatment team and as such participate in joint weekly expert meetings where we discuss each patient's neurovascular diagnosis and recommend a course of action.

 

Intracranial aneurysms

2-3% of the population experience intracranial aneurysms. As a result, aneurysms are often detected incidentally during head examinations performed for other reasons. Some of these aneurysms may require treatment as they pose an increased risk of rupture and bleeding (subarachnoid hemorrhage). For other patients, a regular check-up without active treatment may be sufficient.

For each individual patient, our team will analyze the bleeding risk in-depth, explain the findings, and perform endovascular treatment if necessary. We offer all state-of-the-art minimally invasive treatment modalities, such as coiling (treatment with platinum spirals), and stenting including treatment with flow diverters to reconstruct the affected vessel section.

 

Arteriovenous malformations (AVM)

Deciding on the optimal treatment for this rare and complex intracranial and spinal vascular disease requires in-depth knowledge and profound expertise. We thoroughly examine the localization of the AVM, analyze brain involvement, and evaluate the bleeding risk and - if necessary - the possibility of minimally invasive treatment (embolization).

 

Pulse-synchronous tinnitus

A pulse-synchronous tinnitus presents as a newly perceived whistling noise in the patient's head that follows a heartbeat pattern. It can have physical causes for example a dural arteriovenous fistula, which is a vascular pathology of the hard meninges surrounding the brain (dura mater). Other causes may be rupture of the vessel wall of the cervical arteries leading to the brain or anatomical variants of the cerebral veins. Our team will identify the underlying cause using high-resolution and focused imaging of the head. If the resulting findings suggest a need for therapy, we will perform endovascular treatment.

 

Acute ischaemic stroke

Acute stroke (occlusion of a cerebral vessel) is a very serious disease that often leads to paralysis, changes in language, a significant deterioration in quality of life and even death. In recent years, it has become possible to completely reopen the vascular occlusions using a catheter technique known as mechanical thrombectomy. This treatment saves lives and can make a complete recovery possible. Our team is part of the acute stroke team of the USZ and performs imaging analysis and endovascular treatment in acute situations.
