News | Simple Testing and Minimally Invasive Treatment Could Help Thousands Conceive Naturally—Fallopian Tube Recanalization Offers New Hope
For many women unable to conceive because of blocked fallopian tubes, fallopian tube recanalization—a simple, brief, nonsurgical image-guided procedure—may transform treatment. A University of British Columbia Faculty of Medicine team presented this groundbreaking research at the Society of Interventional Radiology's 2022 annual meeting.
Surprising finding: Many blocked tubes were misdiagnosed
The study analyzed 956 infertility cases from 2015 to 2021. All women had been diagnosed with one or both fallopian tubes blocked on standard **hysterosalpingography (HSG)**. Researchers noted that HSG alone cannot confirm a true blockage, so every patient received a more precise test: selective salpingography.
Nearly 1/4 (23.8%) of the women did not have a true blockage. In many cases, a small mucus plug temporarily covered the tubal opening and was easily cleared with a thin guidewire.
Among women with a true blockage, more than half (56.7%) had tubal patency successfully restored that day through recanalization. Overall, 80.5% of the 956 patients left the outpatient procedure with open fallopian tubes.
Another 15.9% received a more accurate diagnosis of more serious tubal disease, allowing their treatment strategy to be adjusted.
Fallopian tube recanalization: Nonsurgical, outpatient, and completed in 30 minutes
During the test and treatment, a very thin catheter is guided by X-ray through the cervix to the opening of the fallopian tube. Contrast dye is injected to assess patency. If a blockage is found, an interventional radiologist can open it directly with a fine guidewire.
The procedure is usually completed in an outpatient setting with light sedation, without hospitalization, and generally takes less than 30 minutes.
Dr. Lindsay Machan, associate professor of radiology at the University of British Columbia and study lead, said combining imaging diagnosis with minimally invasive treatment supports both medical efficiency and reproductive autonomy:
“This technique gives women an opportunity to try conceiving naturally before undergoing complex and costly treatment. For many patients who cannot afford treatments such as in vitro fertilization (IVF), this low-risk, low-cost approach could be a life-changing step.”
More precise testing, less intervention, and earlier hope
Women increasingly want to participate in treatment decisions, especially during the emotionally and financially demanding experience of infertility. They want accurate diagnoses and to know whether simpler options are available.
This study responds to that need. Researchers called for selective salpingography plus recanalization to be considered a standard option when evaluating female infertility.
“Women have the right to complete, clear information and to participate in creating their own fertility plan,” Dr. Machan emphasized.
