Super-selective distal splenic artery embolization-assisted laparoscopic partial splenectomy for a benign splenic cyst: a case report.

Abstract

Splenic cysts are uncommon, and contemporary management increasingly favors minimally invasive, spleen-preserving approaches. Partial splenectomy provides definitive treatment but may be limited by intraoperative bleeding risk. Selective distal splenic artery embolization (SAE) can reduce arterial inflow, create a parenchymal demarcation plane, and facilitate safer resection. We report the case of an 18-year-old male patient with a recurrent symptomatic splenic cyst who underwent super-selective distal SAE followed by laparoscopic partial splenectomy the following day. Embolization produced a clear revascularized upper-pole segment, enabling precise transection while preserving the remaining spleen. Estimated blood loss was 150 mL, recovery was uneventful, and histopathology confirmed a benign squamous cyst. Follow-up imaging at 3 months demonstrated preserved splenic tissue and no recurrence, with full return to contact sports. To our knowledge, laparoscopic partial splenectomy performed after selective distal SAE for a benign splenic cyst has not previously been described and may expand spleen-preserving options in carefully selected patients.
