Introduction
Haemorrhoidal disease is currently the most common anorectal disorder, with a prevalence of 4%–35% of the population. In most cases it manifests as varying degrees of rectal bleeding, with only 10% requiring surgical treatment.1
Up to now, the reference surgical technique has been the Milligan–Morgan technique, which is essentially open haemorrhoidectomy.2 Since 1990 there have been descriptions in the scientific literature of new surgical techniques aimed at reducing post-surgical pain and achieving complete recovery of the patient in less time. The circular anopexia described by Longo3 reduces the number of days in hospital and the pain is less intense. However, the reported recurrence rates are as high as 15–20% of cases.4
Among the non-excision surgical techniques, ligation of the haemorrhoidal arteries in the distal rectum by Doppler-guided transanal haemorrhoidal dearterialisation (THD Doppler procedure) is associated with less postoperative pain compared to classic surgical techniques and without adverse events in terms of postoperative complications.5, 6
The development of interventional endovascular techniques offers the chance to perform intra-arterial embolisations (IAE) to occlude the superior rectal artery. The advantages of this intra-arterial embolisation technique over transanal haemorrhoidal dearterialisation include the fact that all branches dependent on the superior rectal artery can be identified and therefore embolised, and it is even possible to occlude any anastomoses with the middle rectal artery, thereby removing the risk of rectal trauma.7, 8 Coil embolisation of the superior rectal artery is a well tolerated, effective and safe technique.9, 10
The aim of this paper is to present our results, describing the technique used in the endovascular treatment of haemorrhoids.

Material and methods
This was a retrospective observational study conducted in our hospital and approved by the Research Committee. Informed consent was obtained from each patient.
From September 2017 to April 2019, we included 20 patients with grade II or III haemorrhoidal disease visualised by anoscope or proctoscope, accompanied by significant rectal bleeding (Table 1).
The patients attended the colorectal surgery outpatient clinic, where their medical history was taken and the examination performed. Patients who
Results
The study included 20 symptomatic patients (16 males and 4 females) with grade II and III bleeding haemorrhoids and a mean age of 61.85 (27–81). Two patients had previously undergone haemorrhoidectomy.
The technical success of embolisation of the superior rectal artery was obtained in 18 (90%) of the 20 patients. Clinical success was achieved in 15 (83.4%) out of 18, as one patient required a further embolisation due to recurrence of bleeding and two patients had acute bleeding one month later,
Discussion
In recent years, the published results on the endovascular treatment of haemorrhoids suggest a very encouraging alternative to conventional surgery.8, 9, 11, 12 The findings and results of our study corroborate the benefits of using this procedure, as an end to rectal bleeding is achieved in a high percentage of cases and the postoperative period is virtually painless.
Haemorrhoids are classified into internal and external haemorrhoids according to their location above or below the dentate line.
