✓ The case is presented of a 5-year-old child who suffered a subarachnoid hemorrhage from a giant left vertebral artery-posterior inferior cerebellar artery (PICA) aneurysm. Initial treatment consisted of surgical occlusion of the parent vertebral artery combined with a PICA-to-PICA bypass. Because of persistent filling of the aneurysm, the left PICA was occluded at its takeoff from the aneurysm. Endovascular coil occlusion of the aneurysm and the distal left vertebral artery enabled complete elimination of the aneurysm. Follow-up magnetic resonance imaging and arteriography performed 6 months postoperatively showed persistent occlusion and elimination of the mass effect. Combined surgical bypass and endovascular occlusion of the parent artery may be a useful adjunct in the management of these aneurysms.

✓ The authors present the case of a 34-year-old man struck over the left mastoid region by a hockey puck, who suffered a fatal rupture of a left vertebral artery berry aneurysm. He became apneic within seconds of the injury and had no brainstem reflex within minutes. The postmortem examination showed massive subarachnoid hemorrhage in the posterior fossa and the remnants of a berry aneurysm near the intradural origin of the left vertebral artery, 11 mm proximal to the posterior inferior cerebellar artery. Rupture of a saccular aneurysm as a result of head trauma is rare. This is the first reported case of a posterior circulation aneurysm rupture as a result of head trauma.

Purpose: CTA is becoming the frontline modality to reveal aneurysms in patients with SAH. However, in about 20% of SAH patients no aneurysm is found. In these cases, intra-arterial DSA is still performed. Our aim was to evaluate whether negative findings on CTA can reliably exclude aneurysms in patients with acute SAH. Materials and Method: We conducted a retrospective analysis of all DSA performed from August 2010 to July 2014 in patients with various indications. We selected patient who presented with SAH and had a negative CTA. Findings of the CTA were compared with DSA. Results: 857 DSA were performed during the study period. 51(5.95%) patients with SAH and negative findings on CTA who underwent subsequent DSA were identified. Of these, only 3(5.9%) of patients had positive findings on the DSA. One patient had a posterior inferior cerebellar artery aneurysm on the DSA, not seen on CTA due to the incomplete coverage of the head. Second patient’ CTA did not show any evidence of aneurysm. DSA showed suspicious dissection of the right vertebral artery, potentially iatrogenic. The third patient’s DSA showed suspicious tiny protuberance from left ICA, possibly infundibulum. Conclusion: In patients with SAH, negative CTA findings are reliable in ruling out aneurysms in any pattern of SAH on CT.

A patient in his mid-40s presented with acute basilar artery thrombosis 7 hours postsymptom onset. Initial attempts to perform mechanical thrombectomy (MT) via the femoral and radial arterial approaches were unsuccessful as the left vertebral artery (VA) was occluded at its origin and the right VA terminated in the posterior inferior cerebellar artery territory, without contribution to the basilar system. MT was thus performed following ultrasound-guided direct arterial puncture of the left VA in its V3 segment, with antegrade advancement of a 4 French radial access sheath. First pass thrombolyisis in cerebral infarction (TICI) 3 recanalisation achieved with a 6 mm Solitaire stent retriever and concurrent aspiration on the 4 French sheath. Vertebral closure achieved with manual compression.

Abstract BACKGROUND The ascending pharyngeal artery (APA) may, in very rare cases, supply the posterior inferior cerebellar artery (PICA). In reported cases, when such is the case, the ipsilateral vertebral artery (VA) does not supply the PICA, and most of the time it is hypoplastic. OBJECTIVE To describe a unique cadaveric observation of a direct anastomosis between the posterior division (neuromeningeal) of the jugular branch of the APA and the PICA, where the PICA is also supplied by a normal-size VA. METHODS A direct connection between the APA and the PICA was examined in a cadaveric specimen using a 3-dimensional endoscope and a surgical microscope. RESULTS The enlarged jugular branch of the posterior division of the APA entered intracranially via the jugular foramen in its pars vascularis. It then connected directly with the lateral medullary segment of the PICA. The first segment of the PICA originated from a left vertebral artery of normal size and continued its normal course beyond the junction with the jugular branch of the APA. CONCLUSION Both the VA and the jugular branch of the APA may simultaneously supply the PICA territory. Recognition of this anatomic variant is relevant when planning surgical or endovascular treatments.
