Fluoroscopically-Guided Hysteroscopic Tubal Cannulation: A Procedure for Proximal Tubal Obstruction

Area of Science:

• Reproductive Medicine
• Minimally Invasive Gynecologic Surgery

Background:

• Proximal tubal obstruction is a significant cause of female infertility.
• Traditional treatments may be invasive or have limited success rates.

Purpose of the Study:

• To evaluate the efficacy and safety of fluoroscopically-guided hysteroscopic tubal cannulation (FHTC) for treating proximal tubal obstruction.
• To determine the cannulation success rate, pregnancy rates, and time to pregnancy following FHTC.

Main Methods:

• Retrospective study of 32 infertile women with proximal tubal obstruction.
• FHTC performed using a Novy Catheter under C-arm imaging.
• Evaluation of technical success, complications, and pregnancy outcomes.

Main Results:

• Successful cannulation in 90.6% of subjects and 89.5% of obstructed tubes.
• 100% unilateral patency in bilateral obstruction cases.
• 34.5% intrauterine pregnancy rate within an average of 64.9 days, without in vitro fertilization.

Conclusions:

• FHTC is a safe and effective, incision-free procedure for opening proximally obstructed fallopian tubes.
• Achieves high rates of tubal patency and a rapid return to spontaneous intrauterine pregnancy.
