2025
We present a laparoscopic technique for anatomic S7+S8d resection with right hepatic vein transection, preserving the inferior right hepatic vein and segment S6. Relying on meticulous anatomical landmarks without intraoperative ultrasound, this approach offers a precise and parenchyma-sparing option for dorsally located right-liver tumors, particularly in settings with limited advanced navigation resources.

2025
This protocol presents a novel coronoid-temporalis pedicled flap (CTPF) technique for reconstructing small-to-medium orbital floor defects. CTPF avoids microvascular risks while maintaining biomechanical stability. Clinical cases demonstrate effective structural restoration, reduced complications, and preserved facial symmetry, offering a viable alternative to traditional grafts or alloplastic materials.

Here we describe a newly developed hepatitis B virus (HBV) reporter system to monitor the early stages of the HBV life cycle. This simplified in vitro system will aid in the screening of anti-HBV agents using a high-throughput strategy.
FAQs
They provide complementary blood supplies rather than duplicate pathways. The portal vein brings nutrient-rich blood to the liver, while the proper hepatic artery delivers oxygenated blood. Recognizing this distinction helps explain why the hepatic pedicle contains two functionally different vascular routes and supports accurate interpretation of liver anatomy in biological and clinical settings.
Its bundled organization brings the principal blood inflow and bile drainage pathways together at the porta hepatis. This relationship gives investigators a consistent anatomical reference for tracing vessels and ducts through the liver region. It is especially valuable when correlating normal biology with vascular or biliary disease identified during imaging or surgery.
The bile ducts provide an exit route for bile, while the portal vein and proper hepatic artery provide routes for blood entering the liver. Keeping these pathways conceptually distinct prevents confusion between biliary and vascular anatomy. Their close arrangement also makes the pedicle a useful reference when evaluating abnormalities that affect bile flow or hepatic blood supply.
Temporary pedicle clamping is used to reduce bleeding during hepatic resection. The maneuver applies to the bundled inflow pathway rather than treating the liver as an isolated tissue mass. Its relevance is procedural: understanding the pedicle’s anatomy allows surgeons to identify the structure involved and use temporary control while removing part of the liver.
Radiologists use the hepatic pedicle as an anatomical landmark for recognizing the portal vein, proper hepatic artery, and bile ducts near the porta hepatis. This organized reference supports evaluation of vascular and biliary disease. The associated lymphatic vessels and nerves also form part of the connective-tissue bundle considered when interpreting the region’s anatomy.
In biology, it demonstrates how connective tissue organizes multiple transport and communication pathways at a major liver entrance and exit. In hepatobiliary surgery, the same arrangement guides identification of vessels and ducts during liver procedures. Understanding these relationships supports safer anatomical orientation and explains why pedicle control can help reduce bleeding during resection.
