Abstract
BACKGROUND

We report a rare case of numbness in the right hand, finally diagnosed as bilateral common carotid artery common trunk with aberrant right subclavian artery combined with right subclavian steal syndrome and explain the cause of these diseases.

CASE SUMMARY

The patient was a 65-year-old woman. She complained of dizziness, numbness and weakness of the right hand for 6 mo. She was diagnosed with bilateral common carotid artery common trunk with aberrant right subclavian artery combined with right subclavian steal syndrome by ultrasound, enhanced computed tomography, computed tomography angiography and other examinations. Considering the surgical risks, the patient refused the aberrant right subclavian artery stent implantation and was discharged. We hypothesize that these two kinds of deformity and right subclavian steal syndrome may not occur by accident and result from multiple malformations.

CONCLUSION

Bilateral common carotid artery common trunk with aberrant right subclavian artery combined with right subclavian steal syndrome is rare. This case reminds interventional radiologists of the possibility of these abnormalities before surgery.

Core tip: Bilateral common carotid artery common trunk with aberrant right subclavian artery combined with right subclavian steal syndrome is rare. No other similar domestic or foreign cases have been described. We hypothesized that the occurrence of blood steal syndrome may not be accidental and results from multiple malformations. This case reminds surgeons and interventional radiologists to be aware of the possibility of these abnormalities in patients with aortic arch abnormalities before surgery.
