  • Abstract
  • Look Inside

Four cases of occipital-vertebral anastomosis vis-ualized on common carotid or vertebral angiographies by catheter technique were presented. None of the cases showed any occlusion or stenosis of internal carotid, vertebral, or subclavian artery. The inci-dence of this anastomosis in our institute was only 4 out of 2108 common carotid and 315 vertebral angiograms.

Case I. A 17-year-old male

Clinical diagnosis : cerebral palsy (Fig. 1. a, b, c)

The only anastomotic channel between occipital artery and vertebral artery with relative uniform diameter about 1.7mm was visualized angiographi-cally, but another branches could not recognized.

These findings might suggest direct anastomosis between the two arteries.

Case II. A 15-year-old male

Clinical diagnosis : Occipital neuralgia (Fig. 2. a, b, c)

Case III. A 12-year-old female

Clinical diagnosis : brain tumor (Fig. 3. a, b)

In both cases, common carotid artery and verte-bral artery were communicated through muscular branches.

Case IV. A 16-year-old male

Clinical diagnosis : head injury (Fig. 4. a, b)

Contrast media filled right occipital artery via muscular branches from right vertebral artery, though this anastomosis could not be demonstrated on right common carotid angiogram.
