Cineangiography versus standard digital subtraction angiography in mechanical thrombectomy: lowering the radiation exposure without sacrificing the outcome.

BACKGROUND

Endovascular thrombectomy has become a standard procedure for the treatment of acute ischemic stroke caused by large vessel occlusion. Radiation exposure to the patient and operators during mechanical thrombectomy procedures is a concern.

METHODS

The use of a high frames per second unmasked protocol-cineangiography (CINE)-derived from cardiac intervention could mitigate radiation exposure without sacrificing procedural and clinical outcomes.

RESULTS

The analysis of a prospective-maintained monocentric database of 131 patients who underwent mechanical thrombectomy (65 with the CINE protocol and 66 with the conventional digital subtraction angiography (DSA) protocol) showed a significant reduction in radiation exposure for both air kerma (AK) and dose-area product (DAP) indicators (AK 463.7 mGy vs 772 mGy, P<0.01; DAP 41.35 Gy/cm

CONCLUSIONS

Our initial experience demonstrated that reduction of the quality of CINE images caused no modifications in safety and efficacy and should fit within the context of diagnostic requests in an intracranial revascularization procedure.
