Abstract

The etiology of the vertebral artery dissecting aneurysm (VADA) is unknown and they frequently occur in relatively healthy young men. Therefore, the pathological mechanism by which VADAs occur has not been accurately identified. In this paper, we will examine a case in which a young man complaining of a simple headache became unconscious due to the rupture of a VADA in grew immediately.

Vertebral artery dissecting aneurysm

Figure

• 

  Fig. 1 In A, a subarachnoid hemorrhage with high signal is observed along the sylvian fissure. In B, because of SAH, hydrocephalus is observed.

• 

  Fig. 2 A spontaneous dissecting with vascular dilatation and stenosis is observed in the left vertebral artery. (white circle)

• 

  Fig. 3 No bleeding was observed in the susceptibility weighted imaging of brain MRI and normal findings were found (A,B). In the angiography of brain MRI, no dissection of the vertebral artery observed (white circle)(B).

• 

  Fig. 4 In cerebrovascular angiography, spontaneous dissecting of the left vertebral artery with contrast leakage is observed (white arrow). (A) anterior-posterior view, (B) lateral view.

• 

  Fig. 5 With the coil mass that occluded the aneurysm sac (A, white arrow), cerebral angiography of the left vertebral artery shows complete obstruction of the lesion (B, white arrow). Angiography of the opposite vertebral artery confirmed that there was no blood flow into the lesion retrograde (C, white arrow) (A,B,C: anterior-posterior view).
