Damage of the internal carotid artery (ICA) is very rare but can be a dramatic complication of endonasal sinus surgery. In the literature only a few cases are reported, some of them with fatal results.
Methods
We present two cases with massive bleeding of the ICA caused by endonasal sinus surgery.
Results
In both cases bleeding could be stopped sufficiently by implanting a stentgraft.
Conclusion
The lumen of the artery could be preserved and no neurological deficits were observed.
