Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'атрофия' (atrophy), which is a wasting away. 'Atresia' is specifically a lack of opening or abnormal closure.
- The closest Russian medical term is 'атрезия', a direct cognate, but ensure technical context is maintained.
Common Mistakes
- Misspelling as 'attresia' or 'atresea'.
- Using it to describe an acquired blockage (e.g., from a clot or scar tissue).
- Confusing it with 'stenosis', which is a narrowing, not a complete absence.

FAQ
Frequently Asked Questions
Not exactly. Atresia refers to the congenital absence or severe underdevelopment of a passage. An acquired blockage from a foreign object or a clot is not typically called atresia.
Yes, many forms of atresia can be surgically corrected, especially if diagnosed early. The success depends on the specific organ affected and the severity.
It is most commonly used for tubular structures (intestines, bile ducts, heart valves, ear canals, vagina) and orifices. The specific type is named by the affected part (e.g., pulmonary atresia).
The adjective is 'atretic', used to describe the affected structure (e.g., an atretic valve).
