Cannulation of the popliteal vein as an intraoperative emergency access in prone position: A case report.

Many surgeries have to be performed in the prone position. Access to central vessels is very limited in this position. This requires forward planning with regard to the placement of a central venous catheter. Emergency situations or unexpected intraoperative events in prone position are challenging, as a conventional central venous access is not possible. We describe the cannulation of the popliteal vein in such a case. We report the case of a patient with severe intracerebral hemorrhage who was transferred to our emergency department where his clinical condition rapidly deteriorated. Due to the surgical approach, a prone position was necessary and preoperative central venous cannulation was not possible. We therefore performed an alternative vascular access in prone position using a ultrasound-guided cannulation of the popliteal vein. The cannulation of the popliteal vein described here can be carried out as a quick and easy feasible alternative in emergency situations in prone position. The ultrasound-guided catheter insertion succeeded without any problems and there was no evidence of a deep vein thrombosis after the intervention.
