Background: Mechanical endovascular embolectomy using stent retrievers has gained popularity for treatment of large vessel occlusion in acute ischemic stroke. Use of open embolectomy as a direct surgical treatment has been limited, likely owing to the technical difficulty, therapeutic time window, and time-consuming procedure.
Methods: We retrospectively reviewed clinical and radiographic records of patients who underwent open embolectomy for major artery occlusion at an acute stage. Clinical features, complications, and outcome of patients were analyzed.
Results: From January 2004 to September 2016, 153 patients underwent 157 open embolectomies for major artery occlusion. Complete recanalization was achieved in 96.2% of patients. A favorable outcome was observed in 43.9%. Cerebral aneurysm along the occluded artery was observed in 11 patients with 12 aneurysms.
Conclusions: Open embolectomy resulted in a high complete recanalization rate with an acceptable safety profile. Open embolectomy is a safe and durable method of cerebral recanalization in patients with embolic stroke and can be considered as a potential treatment if endovascular embolectomy cannot be performed. The details of the occluded arteries presented here will be useful for endovascular surgeons to prevent complications.

Catastrophic iatrogenic abdominal aorta haemorrhage during anterior resection.
BMJ Case Rep

General Surgery, Betsi Cadwaladr University Health Board, Bangor, UK
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
January 2025
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.
Cureus
November 2024
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.
