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

Area of Science:

• Vascular Interventional Radiology
• Medical Device Technology
• Aortic Catheterization Techniques

Background:

• Previous catheter techniques were extended to challenging supra-aortic and abdominal aortic interventions.
• Complex aortic anatomy presents significant challenges for diagnostic and interventional procedures.

Purpose of the Study:

• To evaluate the efficacy of a novel dual-lumen catheter (Qureshi-5) for complex supra-aortic and abdominal aortic catheterizations.
• To assess the safety and feasibility of using the Qureshi-5 catheter in patients with severe aortic tortuosity.

Main Methods:

• A new Qureshi-5 catheter with a dual lumen and a curved distal tip was employed.
• The catheter facilitated manipulation using a J-shaped guidewire, allowing for coaxial advancement.
• Diagnostic cerebral and abdominal angiography was performed via a 6F introducer sheath in the right common femoral artery.

Main Results:

• The Qureshi-5 catheter was successfully used for complex supra-aortic and abdominal aortic catheterizations in a single patient.
• Catheterization included the left and right internal carotid arteries, left and right vertebral arteries, left renal artery, and superior mesenteric artery.
• The procedure was performed in a patient with severe aortic tortuosity due to kyphosis, with no observed complications.

Conclusions:

• The Qureshi-5 catheter proved successful in performing complex supra-aortic and abdominal-aortic catheterizations.
• The novel catheter design and technique are effective for navigating challenging aortic anatomies.
