Background:
The persistent primitive trigeminal artery (PPTA) is a persistent embryological carotid-basilar connection. Endovascular thrombectomy (EVT) for hypoplastic PPTA occlusion is a challenge. This case report aims to describe the successful recanalization of simultaneous occlusions in both the PPTA and basilar artery (BA) using the Solitaire FR (RECO SR)/Stent and Intermediate Catheter Assisting (SWIM) technique in a patient with acute cardiogenic cerebral embolism. To the best of our knowledge, this is the first report of such a case.
Case Description:
We present a case of a 70-year-old female patient who presented with acute right-sided hemiparesis and altered consciousness. Digital subtraction angiography confirmed the occlusion of both the distal portion of the PPTA and the BA. The patient underwent EVT using the SWIM technique, resulting in successful recanalization and significant improvement in the patient’s condition.
Conclusion:
This case report demonstrates the successful application of the SWIM technique in achieving recanalization and improving outcomes in a patient with simultaneous occlusion of the acute PPTA and BA. These findings support the potential use of EVT in similar cases.
