ESO Focused Workshop 2023

Unruptured Intracranial Aneurysms and Subarachnoid Hemorrhage

22-24 October 2023  |  Utrecht, The Netherlands  |  Leeuwenbergh


Utrecht was founded in Roman times and flourished in the Middle Ages. Many buildings still date from those times in the old city centre, which is small enough to explore on foot. Utrecht’s cityscape is dominated by the Dom tower, the tallest belfry in the Netherlands. Located centrally in the country, Utrecht is home to one of the largest and oldest universities in the Netherlands.

The University Medical Centre Utrecht has a leading role in genetic and clinical research on patients with ruptured and unruptured aneurysms and has developed over the last years several prediction models for more individualized management of patients with intracranial aneurysms. Moreover, for more than 30 years neurologists are actively involved in the treatment of patients with subarachnoid haemorrhage and intracranial aneurysms, so that the treatment of these patients is truly multidisciplinary.

The aim of the workshop is to make young stroke clinicians and researchers familiar with the management of patients with unruptured intracranial aneurysms and those with subarachnoid haemorrhage, other than occluding the aneurysm. We will address high risk groups for screening for intracranial aneurysms and how to counsel for screening. Further, we will discuss risk of rupture of intracranial aneurysms, the risk of complications of preventive surgical or endovascular treatment and how to balance these risks. Regarding patients with subarachnoid haemorrhage we will discuss the diagnosis, differential diagnosis, and how to prevent and manage complications in these patients. Finally, we will provide insight in research and in new developments for patients with unruptured and ruptured intracranial aneurysms.

The workshop will facilitate stroke physicians to play a role in management of these patients.

The Focused Workshop venue is located in the beautiful medieval center of Utrecht. Built in the 16th century as a “plague house” (which is why it is on the edge of the medieval center), it was later used as a barracks building, church and, in the early 20th century, as a pharmacology laboratory of the medical faculty, among other things. It is now used as a venue for concerts, meetings and symposia.

Travel Information 

Utrecht is well connected to Schiphol Amsterdam Airport.

The most convenient and ecological way to reach Utrecht is by train. If you would decide to travel to The Netherlands by plane, you can take a train from Schiphol airport to Utrecht Central Station. The intercity train runs 4 times per hour, and will take around 30 minutes to reach Utrecht.

The event hotel is in downtown Utrecht, within walking distance from the Central Station.

If you prefer to reach Utrecht by taxi from Amsterdam, we suggest you prebook in advance, for example via Utrechtse Taxi Centrale, which offers a fixed rate of €69.00. A metred taxi ride is considerably more expensive.
