vascular pedicle
Pronunciation: VAS-kyu-lar PED-ih-kul
The main blood supply bundle consisting of arteries and veins that provides circulation to an organ or tissue segment.
Full Definition
A vascular pedicle is the primary neurovascular bundle containing the major arterial inflow, venous outflow, and often lymphatic drainage for a specific organ or anatomic region. In oncologic surgery, identification and control of vascular pedicles is crucial for safe organ mobilization and resection. The pedicle typically includes the main feeding artery, draining vein, and associated lymph nodes that may harbor metastatic disease. Surgical approach to the pedicle often determines the feasibility and safety of organ resection, particularly in hepatobiliary and pancreatic surgery.
Usage
Usage note: Refers to the main blood supply; distinguish from collateral circulation or minor vessels.
