Table 3 Proximal vs Distal Splenic Embolization in Trauma Patients (Ahuja et al. 2015; Imbrogno and Ray 2012; Schnuriger et al. 2011; Killeen et al. 2001)
From: Review of proximal splenic artery embolization in blunt abdominal trauma
Type | When to Perform | Goal of Therapy | Advantages | Disadvantages | Embolics | Potential Complications |
|---|---|---|---|---|---|---|
Proximal | Multifocal injury CT laceration without angiographic correlate | Decrease spleen parenchemyal perfusion pressure. | Shorter procedure times, lower radiation dose | Inability to easily perform future embolization. | Coils and/or plugs | Coil migrationa |
Distal | Trauma patients with focal vascular injury | Selection of specific injured vessels | Selective embolization | Increased procedure time, greater risk of infarction | Coils and/or particles | Splenic infarct and/or abscess formation |
