Insights
Carotid angiographic studies in Saudi Arabia revealed intracranial tumors (50%) and arteriovenous malformations (5.9%). Vertebral angiography is recommended for suspected supratentorial tumors when carotid angiograms are normal.
Area of Science:
- Neurology
- Radiology
- Neuroradiology
Background:
- Cerebral angiography is a diagnostic tool for evaluating cerebrovascular diseases.
- Understanding the spectrum of lesions detected by angiography is crucial for clinical management.
Purpose of the Study:
- To analyze the incidence of various intracranial lesions detected via carotid angiography.
- To evaluate the diagnostic yield and limitations of carotid angiography in a Saudi Arabian population.
Main Methods:
- Retrospective review of carotid angiographic studies.
- Analysis of lesion types and their frequencies.
- Assessment of complications and missed diagnoses.
Main Results:
- Intracranial tumors constituted 50% of detected lesions, with meningiomas accounting for 40%.
- Arteriovenous malformations represented 5.9% of lesions.
- Low incidence of atherosclerosis and arteritis; examination had minimal complications.
- Vertebral artery-supplied lesions were occasionally missed.
Conclusions:
- Carotid angiography is effective in identifying common intracranial pathologies like tumors.
- Vertebral angiography should be considered in cases of suspected supratentorial tumors with normal carotid angiograms to improve diagnostic accuracy.
Abstract:
The carotid angiographic studies performed in a teaching hospital (King Khalid University Hospital, Riyadh) in Saudi Arabia were reviewed, and the incidence of lesions demonstrated was analysed. Intracranial tumours accounted for 50% of the lesions, with meningiomas being 40%, whilst arteriovenous malformations accounted for 5.9% of lesions. It was noted that the incidence of atherosclerosis and arteritis was low, and the examination was almost without complications. Some lesions supplied by vertebral arteries were missed. In view of this, vertebral angiography is advocated in those cases with suspected supratentorial tumour especially when the carotid angiograms are normal.
