Insights
The triple-lumen balloon catheter is a useful tool for performing both CT arterial portography (CT-AP) and CT arteriography (CT-A) sequentially. This technique proved convenient and safe in a study of 58 patients.
Area of Science:
- Interventional Radiology
- Medical Imaging
Background:
- CT arterial portography (CT-AP) and CT arteriography (CT-A) are valuable diagnostic imaging techniques.
- Serial performance of these procedures can enhance diagnostic yield.
- A specialized catheter may improve the efficiency and safety of combined examinations.
Purpose of the Study:
- To assess the utility of a triple-lumen balloon catheter for serial CT-AP and CT-A procedures.
- To determine the feasibility and effectiveness of this catheter in a clinical setting.
Main Methods:
- A cobra-type triple-lumen balloon catheter was used in 58 patients for combined CT-AP and CT-A.
- Contrast administration techniques varied for CT-AP (splenic or superior mesenteric artery) and CT-A (hepatic or accessory hepatic arteries).
- Catheter placement and contrast delivery were optimized using side-holes and end-holes relative to the inflated balloon.
Main Results:
- Successful CT-AP was achieved in 91% (53/58) of patients.
- Successful CT-A was achieved in 72% (42/58) of patients.
- Combined successful CT-AP and CT-A were obtained in 72% (42/58) of patients, with no reported complications.
Conclusions:
- The triple-lumen balloon catheter facilitates convenient and effective serial CT-AP and CT-A.
- This technique offers a safe approach for combined arterial imaging.
- The catheter's design supports versatile contrast delivery for comprehensive vascular assessment.
Purpose:
To evaluate the usefulness of the triple-lumen balloon catheter in the serial performance of CT arterial portography (CT-AP) and CT arteriography (CT-A).
Material And Methods:
A combined CT-AP and CT-A examination of 58 patients was carried out in which a cobra-type triple-lumen balloon catheter was used. CT-AP was performed by injecting contrast medium either into the splenic artery through a side-hole in the catheter proximal to the balloon inflated in the common hepatic artery, or into the superior mesenteric artery through an end-hole in the catheter. Then CT-A was serially performed by delivering contrast medium either to the common hepatic artery or the proper hepatic artery from the end-hole, or to the accessory right hepatic artery through a side-hole proximal to the inflated balloon.
Results:
Sufficient CT-APs were obtained in 53 of the 58 patients (91%), CT-A in 42 (72%), and both in 42 (72%). Incomplete CT-AP was due to technical failure or anatomical anomaly, as was incomplete CT-A. No complications were seen.
Conclusion:
The triple-lumen balloon catheter technique is useful and convenient in the serial performance of CT-AP and CT-A.
