Percutaneous antecubital transvenous cholangiography. A modified technique using a flexible needle

Area of Science:

• Medical Imaging
• Interventional Radiology
• Hepatobiliary Medicine

Background:

• Transvenous cholangiography is an established method for visualizing the bile ducts.
• Existing transvenous techniques may present challenges in terms of ease of use and safety.
• Obstructive jaundice necessitates accurate diagnostic imaging for effective management.

Purpose of the Study:

• To describe a novel percutaneous antecubital transvenous cholangiography technique.
• To evaluate the feasibility and success rate of this new method.
• To explore potential modifications for wider applicability.

Main Methods:

• A flexible 20-gauge needle was utilized for the percutaneous antecubital venous access.
• The technique was applied to patients diagnosed with obstructive jaundice.
• Success was defined by successful opacification of the bile ducts.

Main Results:

• The procedure was successful in 6 out of 8 patients.
• Failure occurred in 2 patients who did not exhibit bile duct dilatation.
• The technique was perceived as easier and safer compared to existing transvenous methods.

Conclusions:

• Percutaneous antecubital transvenous cholangiography is a viable and potentially advantageous technique.
• The method is particularly effective in cases of obstructive jaundice with dilated bile ducts.
• Modifications suggest applicability in femoral approaches and pediatric populations.
