Ictal SPECT With Intra-arterial Injection

Status Withdrawn

Clinical Trial Summary

Ictal SPECT with intravenous injection in a cubital vein of a perfusion tracer is an established technique to localize the ictal onset zone during presurgical evaluation of refractory focal epilepsy. When seizures last less than 10 seconds, localizing information is often not obtained. Since it takes around 30 seconds before the tracer reaches the brain after intravenous injection, ictal hyperperfusion most likely has already switched to postictal hypoperfusion. In this study, we plan to inject the perfusion tracer in the aorta proximal to the cerebral arteries, which will allow a true ictal injection in patients with seizures of short duration.

Clinical Trial Description

In this study, the investigators will select one patient with refractory focal epilepsy with frequent seizures of short duration, which can not be localized with early ictal SPECT with intravenous injection in a cubital vein. An arterial catheter will be inserted. The right groin will be disinfected using an alcoholic disinfectant and locally anaesthetized. The artery in the groin, the femoral artery, will be punctured. A catheter is inserted in the artery and slided towards the heart. To determine the correct position of the catheter proximal to the cerebral arteries, a contrast agent will be injected, and at the same time radiographs will be taken. The catheter will be attached and taped in the groin. The patient will be monitored with video-EEG recording. During an epileptic seizure, the perfusion tracer 99m-Technetium Ethyl Cysteinate Dimer (99mTc- ECD) dissolved in 30 cc normal saline will be injected with a pressure injector over 2 seconds. After injection, the catheter will be removed and the ictal SPECT scan will be performed. Subtracted ictal SPECT images co-registered with MRI (SISCOM) will be obtained. The investigators plan to do this study in one patient in order to assess whether this procedure is logistically possible and to determine whether subtraction images of ictal SPECT with intra-arterial injection minus interictal SPECT with intravenous injection allows localization of the ictal onset zone. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
