Amnesia after femorocerebral angiography

|July 1, 1983
Summary
Amnesia after transfemoral cerebral angiography is rare. Causes include epilepsy exacerbation in younger patients and transient global amnesia in older patients, often linked to emboli.
Area of Science:
- Neurology
- Radiology
- Vascular Medicine
Background:
- Transfemoral cerebral angiography (TFCA) is a diagnostic procedure.
- Amnesia is a potential, though uncommon, complication of TFCA.
- Understanding the causes of post-angiography amnesia is crucial for patient safety.
Purpose of the Study:
- To investigate the incidence and potential causes of amnesia following TFCA.
- To differentiate the types of amnesia observed in patients.
Main Methods:
- Retrospective review of medical charts and radiographs.
- Analysis of 12 patients who developed amnesia after 1,520 TFCA procedures.
- Categorization of amnesia based on patient age and clinical presentation.
Main Results:
- Amnesia occurred in 12 out of 1,520 TFCA patients.
- Younger patients (<40) experienced amnesia attributed to epilepsy exacerbation.
- Older patients (>40) presented with transient global amnesia, with potential links to vertebrobasilar disease or emboli.
Conclusions:
- Amnesia post-TFCA can stem from epilepsy or transient global amnesia.
- Embolic events from catheter manipulation or atheromatous debris are probable causes.
- Further research into preventative measures during TFCA is warranted.
