Acute ischemic stroke attributable to cervical internal carotid artery (ICA) occlusion is frequently associated with severe disability or death and is usually caused by atherosclerosis. By contrast, the cardioembolic cervical ICA occlusion is rare, and feasibility of urgent recanalization remains unclear. We present the first study in the literature that focuses on urgent open embolectomy for the treatment of cardioembolic cervical ICA occlusion. A retrospective review of the charts for patients undergoing open embolectomy was performed. Between April 2006 and September 2007, 640 consecutive patients with acute ischemic stroke were treated. Of them, three patients (0.47%) with the acute complete cardioembolic cervical ICA occlusion underwent urgent open embolectomy. All patients presented with profound neurological deficits and atrial fibrillation. The urgent open embolectomy achieved complete recanalization in all patients without any complications. All emboli in three patients were very large and fibrinous in histological findings. Two of three patients showed rapid improvement in neurological functions after surgical treatments. The cardioembolic occlusion of the cervical ICA is rare, but its possibility should be considered in patients with acute ischemic stroke suffering profound neurological deficits and atrial fibrillation. Urgent open embolectomy may be a treatment option to obtain successful recanalization for cardioembolic cervical ICA occlusion and is recommended because it is technically easier and similar to carotid endarterectomy.

Catastrophic iatrogenic abdominal aorta haemorrhage during anterior resection.

A woman in her 70s with hypertension, breast cancer and diverticulosis underwent laparoscopic anterior resection for a tubule-villous adenoma, converted to open Hartmann's with aorto-bi-iliac bypass due to a vascular injury. Intraoperative complications included haem-o-lok penetration of the calcified aorta, necessitating vascular team intervention. Postoperative issues included bilateral popliteal artery emboli requiring embolectomy and fasciotomy, and a parastomal abscess.

Objective: Infective endocarditis (IE) is associated with significant morbidity and mortality and places patients at risk for subsequent peripheral vascular emboli. Our goals were to analyze the incidence of peripheral emboli and their associated complications and outcomes.
Methods: A retrospective single-center review of all patients with IE from 2013-2021 was performed.
Intra-arterial Alteplase Thrombolysis After Successful Thrombectomy for Acute Ischemic Stroke in the Posterior Circulation (IAT-TOP): Study protocol and rationale.
Int J Stroke

Department of Neurosurgery and Interventional Neuroradiology, Xuanwu Hospital, China International Neuroscience Institute, Capital Medical University, National Center for Neurological Disorders, Beijing, China.
Rationale: The Chemical Optimization of Cerebral Embolectomy (CHOICE) trial suggested that the administration of intra-arterial alteplase after successful endovascular thrombectomy (EVT) may improve neurological outcomes in patients with acute ischemic stroke due to large-vessel occlusion (AIS-LVO) in the anterior circulation. However, the use of adjunctive intra-arterial alteplase following successful EVT in acute posterior circulation stroke remains unexplored.
Aims: This study aims to investigate the efficacy and safety of intra-arterial alteplase after successful EVT for AIS-LVO in the posterior circulation.

Article Synopsis
- The study investigated the Vascular Surgery consults at a Children's Hospital over 4.5 years, documenting patient demographics, types of vascular issues (arterial, venous, etc.), and treatment outcomes.
- Out of 100 consults, most cases involved acute conditions, with the majority of patients being young (average age 8.5 years), and common causes being iatrogenic injuries and trauma.
- While many patients were managed with medical therapy, a small number required surgical interventions, and notably, no vascular-related deaths were reported in the study.
A Rare Case of Acute Aortic Occlusion Mimicking Cauda Equina Syndrome in a Patient With Inflammatory Bowel Disease.

Vascular Surgery, Unidade Local de Saúde São José, Lisbon, PRT.
Acute aortic occlusion (AAO) is a rare and life-threatening condition, mostly secondary to acute thrombosis or embolism. It usually presents as bilateral lower limb ischemia; however, in rare cases, spinal cord infarction might coexist, mimicking cauda equina syndrome. We present a rare case of AAO by saddle embolism of a thoracic aortic mural thrombus.
