Abstract
57 year old healthy woman, with a non-symptomatic aortic aneurysma after a traffic accident 30 years ago and a 70:ty degree thoracolumbar kyfo-scoliosis, was referred for treatment because of severe postural back-pain.
The anticipated treatment was correction of spinal balance with an apical osteotomy, a long instrumentation and maximal number of atachments.
A careful preoperative investigation, including DEXA, bending films, internal medical judgement and vascular surgery consultaion, was performed. The latter ended up in an aortic stent, because of the risks of rupture of the aneurysma, due to elongation of the spine and aorta.
Correction was performed with an oblique 1,5 segment reduction osteotomy in L1 and L2. Blood loss 2 700 ml. Normal neurophysiology during and after the surgery. The patient could return back home after two weeks, protected by a soft brace.
Six weeks after index surgery she became unconscious, got heart arrest and was acute transported to the regional hospital, after resuscitation.
Great amounts of blood were found in the lungs and a CT scan demonstrated a severe elongation of aorta as well as a possible rift at the junction between normal and stented vessel. Two weeks later the patient died, still unconscious. Autopsy confirmed aortic rupture.
CONCLUSION
What are the risks with aneurysma at spinal correction? Should the correction have been performed without the aortic stent?
