**Question:** Purandre's cervicopexy done in:

A. Ovarian ligament
B. Round ligament
C. Internal os
D. Uterine artery

**Core Concept:**
Purandre's cervicopexy is a surgical procedure used in obstetrics to stabilize the cervix during pregnancy, particularly in high-risk cases. The procedure involves tying the cervix to a strong structure to prevent it from slipping into the uterine cavity and potentially causing preterm labor or miscarriage.

**Why the Correct Answer is Right:**
Purandre's cervicopexy is performed using the ovarian ligament, which is a strong and stable structure that connects the ovary to the uterine wall. By tying the cervical os to the ovarian ligament, the cervix is secured and stabilized, reducing the risk of premature labor.

**Why Each Wrong Option is Incorrect:**

A. Ovarian ligament: This option is incorrect because it is not a direct structure attached to the cervix. The procedure involves tying the cervix to a stable structure, not the ovary itself.

B. Round ligament: The round ligament is a thin, weak structure that is not suitable for stabilizing the cervix during pregnancy.

C. Internal os: This option is incorrect because tying the cervix to the internal os would not effectively stabilize the cervix, as the internal os is not a stable structure.

D. Uterine artery: Uterine arteries are not suitable for Purandre's cervicopexy, as they are not stable structures and do not directly connect to the cervix.

**Clinical Pearl:**
Purandre's cervicopexy is a valuable procedure in obstetrics for stabilizing the cervix during high-risk pregnancies. Choosing the correct structure, such as the ovarian ligament, is crucial for the success of the procedure. This knowledge is essential for obstetricians and gynecologists to effectively manage and improve pregnancy outcomes in high-risk cases.
