Purpose:
This manuscript aims to report on a retrospective analysis of six patients treated with combined US- and fluoroscopic-guided percutaneous alcohol sclerosis for primary non-parasitic splenic cysts.
Methods:
In this retrospective analysis, three females and three males affected by primary non-parasitic splenic cysts were included. All except one were symptomatic. Preoperative cyst diameter was in mean 113 mm (range: 67-210 mm). Ethanol 96% was adopted as sclerosant agent; the amount of ethanol injected corresponded to the 20%-30% of the cystic volume. US follow-up was planned at 2/4 weeks; MR follow-up was conducted almost at 6 months after the last treatment session. Technical success was considered as cyst disappearance or reduction of the maximum diameter <50 mm; clinical success, in those symptomatic cases, was considered as symptoms resolution or marked improvement.
Results:
Eleven procedures had been performed: one in three patients, three in two patients and two in one patient. Technical success was 83.3%; clinical success was 80%. Only one patient, with a preoperative cystic diameter of 210 mm and despite three treatment sessions, had an increase in the cystic size and did not report symptoms improvement.
Conclusions:
In this sample, US-guided percutaneous alcohol sclerosis was a safe and effective spleen preserving option to treat primary non-parasitic splenic cysts.
