Background: Although mechanical thrombectomy (MT) represents the standard of care for ischemic stroke due to large-vessel occlusion (LVO), the impact of sex on outcomes in tandem occlusions remains unclear. We investigated sex-based differences in outcomes after MT for tandem occlusions.

Methods: This multicenter observational study included consecutive patients with tandem occlusion treated with MT across three stroke centers (2021-2023).

Performance: Spontaneous dissections of the cerebral arteries are among the leading causes of stroke in young adults. They result from hemorrhage into the outer layers of the arterial wall, which can lead to stenosis or even complete vessel occlusion. Clinical presentations vary, ranging from localized pain to cerebral ischemic complications.

Background: Studies have described a first pass effect (FPE) where patients with successful recanalization after one pass experience better outcomes. Few studies have evaluated this in patients with large core infarctions.

Objective: To determine whether patients with large core infarcts undergoing mechanical thrombectomy in which first pass reperfusion is achieved experience improved outcomes compared with those who undergo more than one pass.

Tandem occlusion due to acute cervical carotid artery dissection should be promptly treated with thrombectomy for reperfusion. If the cervical lesion has reached severe stenosis or complete occlusion, balloon angioplasty and, in certain cases, carotid artery stenting should be performed before thrombectomy for the intracranial lesion. Angioplasty or stent placement is performed in the true lumen, but securing the placement is challenging when the true lumen cannot be determined.

Introduction: This study investigates the influence of carotid artery elongation on neurovascular intervention and outcome in acute stroke treatments proposing an easily assessable imaging marker for carotid elongation.

Methods: 118 patients who underwent mechanical thrombectomy for middle cerebral artery occlusions were included. The carotid elongation ratio (CER), center-line artery length to scan's Z-axis, was measured on the affected side in CT-angiographies.
