Vessel
Right suprarenal vein
A short adrenal connection usually entering the cava
High-yield
Right-to-cava and left-to-left-renal-vein is the standard pattern, with accessory and duplicated adrenal veins as recognized exceptions.
Overview
The principal right adrenal vein usually reaches the inferior vena cava over a short course. Its small caliber, variable insertion and occasional common channel with an accessory hepatic vein distinguish it from the usual left renal-vein route.
Reference facts
- Origin
- Collects cortical and medullary drainage into a principal vein leaving the right adrenal gland.
- Course
- Usually passes a short distance medially toward the posterior or posterolateral caval wall; direction and entry level vary.
- Branches
- Accessory or duplicated channels may connect with phrenic or hepatic venous pathways.
- Supplies
- Carries most venous outflow from the right adrenal gland in the usual arrangement.
- Drains to
- Usually directly into the inferior vena cava, sometimes through a shared or variant venous channel.
Clinical correlation
The short right connection contributes to technical difficulty during selective adrenal venous sampling and to bleeding risk if injured. Some adrenal tumors extend into adjacent venous structures.
