Match each destructive obstetric procedure with its primary operative description: Procedures: 1. Craniotomy 2. Decapitation 3. Cleidotomy 4. Evisceration Descriptions: A. Dividing one or both clavicles to reduce shoulder circumference B. Perforating the fetal calvarium and evacuating intracranial contents C. Excising thoracic or abdominal viscera to reduce trunk volume D. Severing the fetal head from the body

Each operation reduces a different part of the fetal body or separates it to facilitate delivery. Craniotomy reduces the head; decapitation separates head and trunk; evisceration collapses the trunk by removing organs; and cleidotomy reduces shoulder width by cutting one or both clavicles.\n\n**Key takeaway:** Match the procedure to the anatomical obstacle described in the case.\n\n**Glossary:** **Trunk**: The body excluding the head and limbs; **clavicle**: The collarbone; **evisceration**: Removal of internal organs.
