Transcervical Catheterization of the Fallopian Tubes (TCFT)

Transcervical Catheterization of the Fallopian Tubes (TCFT) is the Hilgers-Yeung protocol for clearing partial proximal tubal occlusion using a 3 French delivery catheter and a 0.018-inch flexible-tipped guidewire advanced under fluoroscopic guidance, performed in conjunction with selective hysterosalpingography and intratubal pressure measurement.

Proximal tubal occlusion identified on standard HSG is frequently over-diagnosed. Spasm, debris, and incomplete contrast filling produce false-positive blocks. TCFT does not simply confirm patency: it measures resistance before and after catheterization, confirming that a true mechanical obstruction was present and cleared.

The procedure uses a specialized catheter system advanced to the uterotubal junction under fluoroscopy. A LeVeen pressure-monitoring syringe records intratubal pressure at each step. Hilgers and Yeung reported that over 75% of partially obstructed tubes return to normal patency following catheterization.⁸⁴ TCFT is performed during the proliferative phase and is distinct from generic tubal cannulation in its pressure-measurement component and cycle-timed execution.⁷⁸

For couples with proximal tubal factor, TCFT restores the anatomical pathway for natural conception. It is a restorative alternative to bypassing the tube entirely. The procedure is complementary to selective salpingography and, where occlusion is complete rather than partial, informs the decision for surgical evaluation via fallopian tube recanalization.
