Conservative Treatment of Spontaneous Dissection of the Subclavian Artery

Dissection of the subclavian artery usually occurs as a result of trauma, endovascular interventions or connective tissue disorders. Only rarely has it been described occurring spontaneously. The treatment can be endovascular, open surgery, conservative or a combination of the above. There are no guidelines. The best approach is the one tailored to the lesion itself. This case presents a 73-year-old man with a tiresome and heavy feeling in the right arm. He was diagnosed having a spontaneous dissection of the right subclavian artery, accompanied by a complete occlusion more distally. Because of the relatively minor symptoms he was treated conservatively using anticoagulants. After 6 months of treatment there was complete revascularisation with good pulsations at the right wrist.
