Purpose

To evaluate the 12-month symptom relief rate of super-selective haemorrhoidal artery embolisation (haemorrhoidal artery embolisation) for Grade I-IV internal haemorrhoids and analyse the impact of haemorrhoid grading and embolisation site on treatment efficacy.

Methods

A retrospective analysis was conducted on 32 patients with internal haemorrhoids who underwent haemorrhoidal artery embolisation at the Interventional Radiology Department of The Second Affiliated Hospital of Soochow University between April 2020 and January 2025.

n = 32 patients

Results

over half kept lasting relief a year after embolisation, but nearly half relapsed

100%

Grade I

54.5%

Grade II

50%

Grade III

40%

Grade IV

More results

The Visual Analogue Scale score decreased from 4.25 ± 1.08 preoperatively to 3.53 ± 1.39 at 1 month postoperatively (p < 0.001), rising to 3.72 ± 1.46 at 12 months postoperatively (p < 0.001).

More results

The French Bleeding Scale score decreased from 6.09 ± 1.84 preoperatively to 2.06 ± 1.41 at 1 month postoperatively (p < 0.001), and rebounded to 3.84 ± 2.10 at 12 months postoperatively (p < 0.001).

The 12-month efficacy rate remained at 100% for Grade I haemorrhoids, 54.5% for Grade II, 50% for Grade III, and 40% for Grade IV.

Conclusion · 1 of 3

Haemorrhoidal artery embolisation demonstrates reliable short-term efficacy for bleeding from Grade I-III internal haemorrhoids. As follow-up duration increases and severity grades rise, symptom relief rates gradually decline.

Conclusion · 2 of 3

The procedure is safe and reproducible, serving as an alternative minimally invasive option for patients unwilling or unable to undergo excision for Grade I-III internal haemorrhoids.

Conclusion · 3 of 3

However, patients should be informed of the recurrence risk, and long-term efficacy requires further investigation.
