The Arch of Aorta01:10

The Arch of Aorta

The coronary arteries, originating from the ascending aorta, bifurcate from two sinuses located within the ascending aorta. Positioned just above the aortic semilunar valve, these sinuses house essential aortic baroreceptors and chemoreceptors, crucial for maintaining cardiac function. The left coronary artery and the right coronary artery branch off from the left posterior and anterior aortic sinuses, respectively.
Encircling the heart, the coronary arteries form a ring-like structure before...

Summary

A patient developed neurological deficits after a middle cerebral artery aneurysm coiling procedure. Medical review found no improper treatment, concluding the infarct was not due to medical error.

Area of Science:

  • Neurology
  • Neurosurgery
  • Vascular Neurology

Background:

  • A 44-year-old female presented with an incidental left middle cerebral artery aneurysm.
  • The patient underwent endovascular therapy using coiling for aneurysm treatment.

Observation:

  • Post-extubation, the patient developed hemiparesis.
  • Subsequent symptoms included speech disturbance and disorientation.
  • Imaging revealed a left lenticular nucleus infarct.

Findings:

  • Angiography demonstrated occlusion of a frontal opercular branch of the left middle cerebral artery.
  • A medical liability fact-finding board reviewed the case.
  • A neuroradiologic opinion was obtained.

Implications:

  • The board concluded that the infarct and subsequent neurological deficits were not caused by improper medical treatment.
  • The management of the complication was deemed adequate.
  • This case highlights the importance of thorough neuroradiologic evaluation in post-procedural complications.
