AP-HP, in collaboration with the Hartmann Institute of Radiosurgery and Radiotherapy, part of the ELSAN group, is offering ZAP-X® at Lariboisière.

One of the most advanced forms of stereotactic radiosurgery for the treatment of brain tumors and certain functional disorders.

information on radiosurgery

Radiosurgery

Radiosurgery at Lariboisière, state-of-the-art technology.
What is it?
ZAP-X® technology
Patient benefits

High-precision irradiation technique

Radiosurgery (or stereotactic radiotherapy) has become essential in the management of many intracranial and skull base lesions, including tumors (benign or malignant), vascular anomalies (arteriovenous malformations and cavernomas), and functional disorders.

The ZAP-X®: a highly precise X-ray scalpel

This technique is particularly useful for treating deep-seated tumors where surgical intervention would be too risky. Unlike conventional radiotherapy, radiosurgery requires very few sessions... sometimes just a single one.

The Patient Journey

Your simplified journey: from consultation to treatment

Consultation

Step 1

Nursing support time

Step 4

Locating imaging

Step 3

Medical validation

Step 2

ZAP-X treatment

Step 5

With ZAP-X, therapy can be considered for a wide range of pathologies. Each case is assessed individually through interdisciplinary collaboration between specialists, including radiation oncologists, neurosurgeons, neurologists and neuroradiologists.

Simplified care pathway

Prior to treatment, a multidisciplinary consultation meeting (RCP) is held to confirm and validate the indication for radiosurgical treatment, based on the patient's pathology.

Consultation
A medical electroradiology technician accompanies the patient for a period of time. This time is used to explain the different stages of the patient's treatment.
Locating imagery
The center's team organizes the imaging examinations essential for treatment, which systematically include a simulation CT scan using a thermoformed mask to ensure that the patient is in the same position as during treatment. MRI with specific sequences is also performed in the majority of cases, and arteriography is scheduled when the treatment concerns cerebral arteriovenous malformations.
Zap-X® treatment appointment
The patient is quickly settled in for treatment, with the thermoformed mask produced during the simulation scan put back into place. The duration of each session varies according to the pathologies to be treated, but is usually around 30 minutes.
