Dear Editor,

Endovascular neurosurgery is a strongly imaging-dependent discipline. The precision and complication avoidance in such procedures depends on interaction of the interventionist with the imaging interface, as well as awareness of the biplane machine. Simulation techniques provide training of neurosurgical residents in targeted subspecialties, in a controlled manner without any risk to patients.[1],[2] Various simulators have been used to improve residency programs in endovascular neurosurgery.[3] However, they do not give hands-on experience in the Cath lab. We have devised an extremely low-cost method of providing hands-on experience to residents and technicians to various imaging sequence and image acquisition techniques in a Cath lab.

A skull bone that was split in the midsagittal plane was taken. Tubing of saline infusion set was taken and entry of tubing was done through foramen in the skull base. The tubing was coiled in the skull and the exit of the tube was connected to an empty saline bottle [Figure 1]a. A syringe with 20 ml contrast was taken. The skull bone was used as a dummy to learn centering in the frontal and lateral plane by the residents and technicians [Figure 1]b. The contrast was infused in the saline tube and various modes of the operator footswitch like fluoro/digital subtraction angiogram (DSA)/cine mode were practiced. A 3D rotation angiogram [Figure 2]a, DynaCT [Figure 2]b was performed using the same skull bone model. A used guidewire was used to pass through the saline tubing to learn the road map technique [Figure 2]c. Adequate measures to protect from radiation were taken by all participants. A pre and post-simulation feedback was obtained and the students/technicians were better versed with regard to handling the biplane machine and acquiring various imaging sequences and image acquisition techniques in a Cath lab, post the simulation procedure.

The authors describe a novel, simple yet cost-effective method for hands-on learning by residents and technicians in Cath lab for understanding the imaging acquisition techniques as well the operative technique of the bi-plane in a Cath lab. This method can be used in addition to the various described virtual reality simulation of neurointervention procedures, especially in the early phase of training to provide knowledge of operating the bi-plane Cath lab to residents and technicians.
