Morphology
The phrase is compositionally transparent: 'sigmoid' denotes relation to the sigmoid colon and 'vein' denotes a blood vessel, so the combined meaning is a vein associated with/draining the sigmoid colon. This follows regular anatomical naming patterns (common cross-linguistically), so a learner who knows both constituent meanings can infer the MWE's meaning even if the term is technical.
Etymology
Sigmoid vein: The name sigmoid vein comes from the S shape of this vein near the sigmoid part of the colon. Sigmoid means 'S-shaped' and a vein is a blood vessel that 'drains' blood, so the name tells you both its shape and its job.
