Q) Lymphatic drainage of Right adrenal gland is to
a) Para aortic group
b) Inter Aortocaval
c) Pre aortic
d) Para Caval
Correct Answer: d) Para-caval for right and Para aortic for left
Small lymphatic channels from both cortex and medulla drain into the hilum, from where larger calibre lymphatic emerge to drain directly into the lateral group of para-aortic lymph nodes.
- Right side adrenal → Para-caval
- Left side adrenal → Para-aortic
Arterial supply:
- Superior adrenal artery (from inferior phrenic artery)
- Middle adrenal artery (from abdominal aorta)
- Inferior adrenal artery (from renal artery)
Venous drainage:
- Left adrenal vein → Left renal vein
- Right adrenal vein → IVC
Understanding lymphatic, arterial and venous drainage of the adrenal gland is critical in adrenalectomy and adrenal trauma surgery.
