Hypersplenism Treated by Partial Splenic Embolization Using Guglielmi Detachable Coils.

Area of Science:

• Interventional Radiology
• Vascular Surgery

Background:

• Partial splenic embolization (PSE) is a treatment for hypersplenism.
• Conventional coil embolization can face challenges with large intrasplenic arteries and short branching distances, risking coil migration.

Observation:

• A 52-year-old male patient with hypersplenism underwent PSE.
• The target intrasplenic artery was large with short trifurcated branches, posing a technical challenge for coil stability.

Findings:

• Guglielmi detachable coils (GDC) 360° Complex Shape, combined with conventional coils, were utilized to prevent migration.
• GDC's shape-memory function and 3D loop formation provide superior physical stability compared to conventional coils.
• An ideal splenic infarction was achieved with a minimal number of GDC coils.

Implications:

• This case represents the first reported use of GDC in PSE for hypersplenism.
• GDC coils offer a potentially safer and more effective embolization method for complex splenic artery anatomy.
• This technique may improve outcomes and reduce complications in patients with hypersplenism requiring PSE.
