Newly devised long sheath for transfemoral angiography

Area of Science:

• Vascular Surgery
• Interventional Radiology
• Medical Device Innovation

Background:

• Percutaneous transfemoral angiography is crucial for diagnosing iliac artery conditions.
• Navigating tortuous iliac arteries presents significant challenges during catheterization.
• Existing sheaths may be inadequate for complex arterial anatomy.

Purpose of the Study:

• To introduce and evaluate a novel long sheath designed for challenging iliac artery catheterization.
• To assess the efficacy of the new sheath in percutaneous transfemoral angiography.

Main Methods:

• Development of a specialized long sheath with enhanced flexibility and trackability.
• Clinical application of the sheath in patients with markedly tortuous iliac arteries.
• Comparison of procedural success rates and ease of use with conventional methods.

Main Results:

• The newly devised long sheath successfully facilitated catheterization in all cases of tortuous iliac arteries.
• Reduced manipulation time and improved guidewire stability were observed.
• The sheath demonstrated excellent trackability and safety profile.

Conclusions:

• The novel long sheath is an effective tool for navigating tortuous iliac arteries during transfemoral angiography.
• This device offers a significant advantage in improving procedural success and patient safety.
• Further studies are warranted to explore its utility in diverse vascular interventions.
