Cyst puncture (obstetrics)

Cyst Puncture (Obstetrics): A Diagnostic and Therapeutic Procedure During Pregnancy

Cyst aspiration in obstetrics is a medical procedure in which a needle is inserted into a cyst, most commonly an ovarian cyst, present in a pregnant woman to obtain a fluid sample for analysis or to remove excess fluid. This procedure is performed to determine the nature of the cyst, relieve symptoms, and help prevent potential complications during pregnancy.

What Is Cyst Puncture In Obstetrics?

Cyst puncture is an invasive procedure performed under sterile conditions, usually with ultrasound guidance. During pregnancy, various types of ovarian cysts may develop. Most are benign and resolve spontaneously. However, some cysts may become large, cause pain or pressure, or raise concerns regarding their nature. During the procedure, a fluid sample is collected and sent to a laboratory for cytological and biochemical analysis. These tests help determine the type of cyst and assess whether malignant cells are present. When performed for therapeutic purposes, fluid removal may reduce the size of the cyst and alleviate symptoms.

Why Is Cyst Puncture Performed During Pregnancy?

Cyst puncture in obstetrics is most commonly indicated when:

• A large ovarian cyst is present and causes pain, pressure, or other symptoms.
• Cyst rupture or torsion is suspected, particularly in cases of acute abdominal pain.
• There is concern about possible malignancy, based on ultrasound findings or other diagnostic investigations.
• Symptom relief is needed by draining excess fluid from the cyst.
• Differential diagnosis is required to distinguish the cyst from other abdominal conditions when the cause of abdominal pain during pregnancy is unclear.

Procedure Overview:

Cyst puncture is performed under sterile conditions with ultrasound guidance.

1. Preparation: The patient is positioned on the examination table, and the puncture site is disinfected.
2. Anesthesia: Local anesthesia may be administered if necessary.
3. Needle insertion: Using ultrasound guidance, the physician carefully inserts a thin needle into the cyst.
4. Fluid aspiration: A fluid sample is withdrawn using a syringe.
5. Laboratory testing: The collected fluid is sent for laboratory analysis.
6. After the procedure: The needle is removed, and the puncture site is covered with a sterile dressing. The patient is observed for a period of time following the procedure.

Interpretation of Results:

The results of cyst puncture, including cytological and biochemical analyses, help determine the nature of the cyst (benign, borderline, or malignant), identify the presence of infection, and detect other pathological changes. These findings provide important information for the treating physician, supporting an accurate diagnosis and the development of an appropriate management plan during pregnancy.
