Qureshi-5 Catheter for Complex Supra- and Abdominal-Aortic Catheterization.

BACKGROUND: The use of previously described catheter technique was expanded to complex supra- and abdominal- aortic catheterizations.

METHODS: A new (Qureshi 5) catheter with curved shape at the distal end that has two lumens was used. One of lumens can accommodate a 0.035-inch guide wire and the second lumen can accommodate a 0.018-inch guide wire and terminates at the beginning of the distal curve of the first lumen. The manipulation and engagement of the curved distal end catheter was facilitated by rotation and movement of the J-shaped 0.018-inch guide wire extended coaxial and beyond the distal end of catheter. Subsequently, either contrast was injected or a 0.035-inch guide wire advanced into the target artery.

RESULTS: The catheters were used in one patient to perform diagnostic cerebral and abdominal angiography through a 6F introducer sheath placed in the right common femoral artery. The catheterization was complex because of severe tortuosity of arch and descending aorta secondary to kyphosis. The left and right internal carotid arteries and left and right vertebral arteries, left renal artery, and superior mesenteric artery were catheterized in patient (fluoroscopy time 19:46 min). No complications were observed in the patient.

CONCLUSIONS: The Qureshi-5 catheter was successful in complex supra- and abdominal-aortic catheterizations.
