Name possible causes of RHA infarction.
A list of causes may contain, but not be limited to, former surgery near the origin of the artery (probably most often), small vessel disease, ipsilateral saddle thrombus, and rarely, dependent of the origin of the vessel, contralateral MCA infarction.
True or false: Changes represent large vessel disease.
False. While atherosclerotic changes in ICA represent large vessel disease (LVD), atheroma of the penetrating arteries are classified as small vessel disease (SVD).
True or false: Digital subtraction angiography DSA is indicated.
There is no definite answer to this question. While the recurrent artery of Heubner (RHA) usually is not visualized on DSA, case reports have shown DSA is able to show atheromatous changes in the course of the artery. Of interest casuistic reports have demonstrated a possible role for high resolution magnetic resonance imaging HR-MRI in capsular warning syndrome.
