Summary
A rare vascular anatomy may complicate recovery after anterior cerebral artery bypass surgery. This case highlights a potential cause of neurological decline, emphasizing the need for careful surgical planning and postoperative monitoring.
Area of Science:
- Neurology
- Neurosurgery
- Vascular Anatomy
Background:
- Anterior cerebral artery (ACA) stenosis can cause severe neurological deficits.
- Revascularization surgery, such as superficial temporal artery (STA)-ACA bypass, is a treatment option.
- Understanding vascular anatomy is crucial for surgical success.
Observation:
- A 71-year-old female presented with transient ischemic attacks (TIAs) due to left ACA stenosis.
- She underwent a left STA-ACA bypass with an interposed graft.
- Postoperatively, she developed right-sided hemiparesis.
Findings:
- Watershed shift infarction was identified as the cause of neurological deterioration.
- A specific, risky vascular anatomic orientation was implicated.
- This anatomical variation may impact postoperative hemodynamics.
Implications:
- This case underscores the importance of recognizing unusual vascular anatomy in ACA revascularization.
- It highlights a potential cause of postoperative neurological complications.
- Careful preoperative assessment and tailored surgical strategies are essential for optimizing outcomes.

The human body's intricate network of arteries ensures that every organ system receives the necessary oxygen and nutrients for optimal function. The arterial network in the head and neck region is particularly complex, providing vital blood flow to the brain, eyes, and other critical structures. Prominent arteries in this region include the internal carotid arteries and the vertebral arteries.
The internal carotid arteries supply blood to the anterior portion of the cerebrum. They enter the...

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.
