Preliminary Experience with use of Qureshi-5 Catheters for Diagnostic Cerebral Angiography

Abstract

BACKGROUND—A catheter technique was developed to overcome current challenges in the stabilization
and manipulation of catheter in tortuous arteries such as right subclavian artery and left common carotid
artery.
METHODS—The new catheter has the following two lumens: first lumen can accommodate a 0.035-inch
guide wire (lumen A) and a curved shape at the distal end; the second lumen can accommodate a 0.018-
inch guide wire and terminates at the beginning of the distal curve of the first lumen (lumen B). The catheter is withdrawn or advanced over the 0.018-inch guide wire and the curved free end of catheter manipulated until the end engages the origin of the target artery. Subsequently, either contrast can be injected or a
0.035-inch guide wire advanced into the target artery.
RESULTS—The catheters were used in two patients to perform diagnostic cerebral angiography through a
6F introducer sheath placed in the right common femoral artery. The left and right common carotid arteries
and left and right vertebral arteries were catheterized in first patient (contrast used 50 ml; fluoroscopy time
20:09 min). The left and right internal carotid arteries, left and right subclavian arteries, and left external
carotid artery were catheterized in second patient (contrast used 40 ml; fluoroscopy time 13:56 min). No
complications were observed in either of the two patients.
CONCLUSIONS—The performance of the new catheter for catheterization of multiple arteries in two
patients was considered adequate with high-quality angiographic image acquisitions.
