A new catheter for selective and superselective angiography.

Area of Science:

• Interventional Radiology
• Vascular Surgery

Background:

• Selective abdominal angiography is crucial for diagnosing visceral artery diseases.
• Superselective catheterization allows precise targeting of small visceral branches.
• Existing catheters may have limitations in accessing distal visceral vessels.

Purpose of the Study:

• To introduce a novel femorovisceral catheter.
• To evaluate its efficacy in selective and superselective abdominal angiography.
• To assess its utility in embolization and infusion procedures.

Main Methods:

• Development of a new femorovisceral catheter design.
• Application of the catheter for routine selective abdominal angiography.
• Utilization for superselective catheterizations to fourth-order visceral branches.
• Performance evaluation in embolization and infusion procedures.

Main Results:

• The new femorovisceral catheter facilitates routine selective abdominal angiography.
• It enables superselective catheterization of up to fourth-order visceral branches.
• The catheter demonstrated particular effectiveness in embolization procedures.
• It also proved effective for infusion therapies.

Conclusions:

• The novel femorovisceral catheter is a valuable tool for advanced abdominal angiography.
• Its design enhances precision for superselective visceral interventions.
• This catheter improves outcomes for embolization and infusion treatments.
