Results
3D RA with DUAL VOLUME VISUALIZATION
ALSO HELPFUL WHEN …
# Aneurysm: Virtual Localization of Distal Dural Ring (Figure 5)
- Visualization of virtual plane of DDR and localization of the paraclinoid ICA aneurysm in relation to the DDR is feasible with 3D RA
Lee et al.,
Neurointervention 2010;5:85-90
# Dural AVF
- Benefit of Rotational DSA
- The presence of shunted venous pouch is a common angioarchitecture of transverse sinus dAVFs,
and identification of this pouch with rotational angiography would be useful for their treatment.
Kiyosue et al.,
AJNR 2013
- Benefit of dural rotational DSA with dual volume visualization
- Easy to recognize relationship between venous sinus and neighboring base of skull
- Help to planning venous acess
- Help to navigate the microcatheter and microguidewire
- Help to confirm the targetted venous pouch
- Case: F/63,
Dural AVF (Figure 6)
- AV shunt from inferolateral trunk of left ICA,
with venous drainage into contrallateral cavernous sinus and then into the superior ophthalmic vein.
- Case:F/63,
Dural AVF (Figure 7)
- Benefit of rotational DSA with dual volume visualization
- Relationship of islolated left transverse sinus and basal bone
- Help to guide navigation of microcatheter and microguidewire to this isolated venous pouch through blind track
# Spinal Vascular Malformation
- 3D angiography was safe and useful for evaluation of the 3D vascular anatomy of spinal vascular malformation
Prestigiacomo et al.,
AJNR 2003;24:1429-1435
- Case: M/53,
Spinal dAVF @ T6 (Figure 8)
- Benefit of Rotational DSA with dual volume display
- Full set of vascular volume displayed with mask volume set of spine and soft tissue
- Enabling easy recognition of lesion location and its relationship with spine
