Abstract
Acase of successful transcatheter arterial embolization by a
double-catheter technique using anchoring coils for splenic artery
aneurysm is reported. The double-catheter technique was planned
for embolization of a markedly tortuous artery.
A 3Fr. catheter is inserted into the distal end of the aneurysm
via the aneurysm and the tortuous artery through a 5Fr. catheter
which is placed in the celiac or the splenic artery via the right
femoral approach.
After withdrawal of the 5Fr. catheter only, alone 5Fr. catheter
is inserted at the proximal end of aneurysm via the left femoral
approach.
Anchoring coils and coils(corresponding to a 0.035 inch guide
wire) are placed at the proximal end of the aneurysm through
the 5Fr. catheter, and then microcoils(corresponding to a 0.018
inch guide wire) are placed at the distal end of aneurysm through
a 3Fr. catheter. Finally, the 3Fr. catheter is withdrawn.
The advantages of this technique are its high technical success
rate of embolization for a tortuous artery, limitation of embolized
area, protection against coil migration and economical performance.
On the other hand, its disadvantages are the troublesome and
highly invasive technique, but the use of a balloon catheter
and/or Y-shaped sheath make up for these disadvantages.
