PLB | TJLB | |
---|---|---|
Localization | May be image-guided or ‘blind’ (using physical exam to localize) | Localization with fluoroscopy is not as accurate |
Technical factors | Shorter (mean 10 min), may have radiation (CT-guided) exposure | Longer (mean 22 min), radiation exposure |
Diagnostic yield and accuracy | Higher diagnostic yield because of parenchymal image guidance, and typically larger needle caliber (18 gauge or higher) | Comparatively, less diagnostic accuracy because a smaller needle caliber is used |
Cost | Lower cost | Higher cost |
Complications | Pain is more commonly reported than with TJLB | Bleeding risk is comparable with PLB |
Coagulopathy | Lower threshold for correction (INR: 1.5; platelets: ≤50 000–70 000) |
Higher threshold for correction (INR: 1.7–1.9; platelets: ≤50 000) |
Other | Useful for evaluation of hepatic masses | Useful to measure HVPG and assess hepatic vascular structures |
HVPG, hepatic venous pressure gradient; INR, international normalized ratio; PLB, percutaneous liver biopsy; TJLB, transjugular liver biopsy.
