Insights
Doppler sonography effectively diagnoses cerebrovascular insufficiencies, with a complete ultrasound investigation showing 80% sensitivity for internal carotid artery issues. This non-invasive method aids in identifying vascular conditions.
Area of Science:
- Vascular Medicine
- Diagnostic Imaging
- Neurology
Background:
- Cerebrovascular insufficiencies and asymptomatic vascular noises pose diagnostic challenges.
- Accurate assessment of carotid and vertebral arteries is crucial for stroke prevention.
Purpose of the Study:
- To evaluate the diagnostic efficacy of Doppler sonography in patients with suspected cerebrovascular insufficiencies.
- To compare the sensitivity of the supratrochlear compression test with a comprehensive ultrasound investigation for internal carotid artery stenosis.
Main Methods:
- 45 patients with cerebrovascular insufficiencies or vascular noises underwent Doppler sonography followed by angiography.
- Ultrasound investigation included assessment of common carotid, internal and external carotid, vertebral, subclavian, and supratrochlear arteries.
- Supratrochlear compression test was specifically evaluated for diagnosing internal carotid artery stenosis.
Main Results:
- The complete ultrasound investigation demonstrated approximately 80% sensitivity in diagnosing high-degree stenoses and occlusions of the internal carotid artery.
- The supratrochlear compression test showed a sensitivity of 50% for detecting these internal carotid artery conditions.
- Doppler sonography provided valuable insights into the patency of major cerebral and peripheral arteries.
Conclusions:
- Comprehensive Doppler sonography is a highly sensitive tool for evaluating cerebrovascular insufficiencies.
- While the supratrochlear compression test has moderate sensitivity, the overall ultrasound approach offers significant diagnostic value.
- Ultrasound Doppler sonography presents a favorable balance of advantages and disadvantages for non-invasive vascular assessment.
Abstract:
On account of cerebrovascular insufficiencies or asymptomatic vascular noises which had taken place 45 patients were examined by means of Doppler sonography and after this by means of angiography. The judgement of the common carotid artery, the internal and external carotid arteries, the vertebral artery, the subclavian artery and the supratrochlear artery were involved into the ultrasound investigation. The sensitivity of the supratrochlear compression test was 50% in the diagnosis of high-degree stenoses and occlusions of the internal carotid artery, whereas the sensitivity of the complete ultrasound investigation way about 80%. The advantages and disadvantages of the ultrasound Doppler sonography investigation are discussed.
