Introduction
Caesarean scar pregnancy (CSP) is a relatively rare yet life-threatening condition in which the embryo is implanted in the scar after caesarean section. Recent studies have reported that uterine artery chemoembolisation (UAC) can be safe and effective method in treating CSP.

Aim
To present the clinical outcome of UAC with a mixture of methotrexate and gelatine sponge for the treatment of CSP and analysis of procedural failure.

Material and methods
Forty-one patients diagnosed with CSP were treated with selective endovascular chemoembolisation of uterine arteries. Short- and long-term results, reasons for procedural failure, and clinical outcome were analysed.

Results
Primary procedure failed in 7 out of 41 (17%) cases. In 4 cases additional blood supply to the CSP was disclosed; 3 out of 4 from an ovarian artery and one from a superior vesical artery. In other 3 patients, reperfusion of uterine arteries was observed. All these 7 patients underwent successful secondary embolisation. The majority of the followed-up patients reported regular menses after the intervention. Four women suffered from amenorrhoea and 2 from hypomenorrhoea that continued after 90 days. Twelve patients expressed the desire for subsequent pregnancy. From this group, 5 conceived within a year of the procedure. The rest did not achieve a pregnancy.

Conclusions
UAC proved to be a safe and effective method and should be considered as an option for CSP treatment, especially for women hoping to preserve their fertility. However, the presence of collateral blood supply should always be considered.
