Catheter, VTK

#catheter

The VTK catheter is designed to select the target artery from the aortic arch (Case 1), especially in type II and III. It typically forms without the need of a wire. Its design does not involve advancing it into the target artery; instead, it remains in the aortic arch.

Catheter Specifics

Cases

1


This case illustrates how the VTK catheter can be utilized to select the right ICA.

(A): Advance the VTK catheter into the ascending aorta and gently retract it until the tip (orange arrow) "pops" into the right CCA, as confirmed on this PA roadmap.
(B): Simultaneously captured with (A), this lateral view focuses more rostrally on the CCA and distal cervical ICA.
(C and D): Gently advance the Glidewire tip (black arrow) into the distal cervical ICA (D) to straighten the VTK catheter (C).
(E): Slowly advance the guide catheter, in this case, the Walrus catheter, into the CCA while firmly holding the VTK catheter.
(F): Continue advancing the Walrus until its tip (green arrow) reaches the distal cervical ICA in a stable condition.

2 Bovine Arch

2.1


This patient has a bovine-type arch, and the VTK catheter makes the selection of the left CCA straightforward.

2.2


To achieve catheterization of the right CCA, the VTK catheter tip (orange arrow) is first placed in the bovine arch to obtain a roadmap (A). The Glidewire (black arrow) first enters the left CCA following the trajectory of the VTK catheter (B). Gentle push of the VTK catheter will "pop" its tip out of the left ICA into the brachiocephalic artery (C). Gently advance the Glidewire into the right CCA until the VTK catheter is strengthened (D). Firmly hold the VTK catheter and advance the guide catheter (green arrow) to follow the Glidewire into the right CCA (E).
