Aberrant anatomical variation of the vertebral artery (VA) from an internal carotid artery (ICA) is considered a rare finding. The incidence of this phenomenon can lead to patients suffering from posterior circulation neurological deficit if the ICA becomes significantly diseased. VA atypical anatomical origin is considered one of the rare pathologies, not only precipitating neurovascular incidents but equally leading to severe difficulty in VA dissection and surgical exposure, especially in carotid artery procedures.

Introduction Coronavirus-19 (COVID-19) plays a vital role in viral-induced hypercoagulability through the initiation of a cytokine storm. This mechanism has been found to predispose unvaccinated patients to systemic complications including arterial thrombosis (AT) with poor 30-day amputation-free survival rates. There remains, however, little understanding regarding the incidence in patients who have received a COVID-19 vaccination.

Background: Management of juxtarenal abdominal aortic aneurysms (JRAAA) remains challenging. Both open surgical and endovascular options are feasible, however, there is lack of level 1 evidence to support one modality over the other. Operative interventions frequently necessitate either open repair with a suprarenal clamp positioning (ORSRC) or complex endovascular repair (EVAR) with fenestrated (fEVAR) or parallel stent grafts (chEVAR).

This literature review discusses the current evidence on acute limb ischemia (ALI) in patients with COVID-19. Throughout the pandemic, these patients have been at increased risk of arterial thrombotic events and subsequent mortality as a result of a hypercoagulable state. The exact mechanism of thrombosis is unknown; however arterial thrombosis may be due to invasion of endothelial cells via angiotensin-converting enzyme 2 (ACE2) receptors, endothelial injury from inflammation, or even free-floating aortic thrombus.

Objectives: Patients presenting with digital upper limb ischaemia are occasionally referred to rheumatology services to rule out vasculitis. We aimed to present two cases of delayed diagnosis of arterial thoracic outlet syndrome (aTOS) in middle-aged patients presenting with digital ischaemia in order to raise awareness of this important pathology that requires timely surgical intervention.

Methods: Two cases of progressive ischaemia of the right upper extremity caused by primarily undiagnosed compression of the subclavian artery by an accessory cervical rib are presented.

Objective: Despite an increasing elderly population there is limited evidence regarding the surveillance and management of small abdominal aortic aneurysms (AAAs) in octogenarians. This study investigated outcomes of patients aged ≥85 years undergoing AAA surveillance to identify whether discontinuation of surveillance might be safe.

Methods: This was a retrospective cohort study of all patients aged 85 years undergoing surveillance with a small (30-54 mm) AAA between January 2007 and November 2017.

Background: Stents are placed in the femoropopliteal arteries for numerous reasons, such as atherosclerotic disease, the need for dissection, and perforation of the arteries, and can become stenosed with the passage of time. When a stent develops a flow-limiting stenosis, this process is known as "in-stent stenosis." It is thought that in-stent restenosis is caused by a process known as "intimal hyperplasia" rather than by the progression of atherosclerotic disease.

We describe the case of a 36-year-old man with bilateral axillary artery aneurysms and a threatened upper limb. We postulate that his aneurysms and diffuse vasculopathy resulted from a missense mutation identified in his ACTA2 gene known to be highly pathogenic. The risk factors and sequelae of axillary aneurysms are reviewed, with a focus on their surgical management and the effect of ACTA2 mutations on the cardiorespiratory system.

Background: Constructive feedback plays an important role in learning during surgical training. Standard feedback is usually given verbally following direct observation of the procedure by a trained assessor. However, such feedback requires the physical presence of expert faculty members who are usually busy and time-constrained by clinical commitments.

Introduction: Popliteal artery aneurysms (PAA) are the most prevalent form of peripheral arterial aneurysms. Greater saphenous vein grafts and endoaneurysmorrhaphy remains the mainstay therapy for open repair of PAA. True aneurysmal degeneration of lower extremity infrainguinal autologous vein grafts are relatively rare and its etiology is not completely understood.

The treatment of chronic mesenteric ischemia remains challenging and controversy exists over the best interventional option. Endovascular treatment has emerged as first-line management due to its associated lower morbidity and mortality than surgical reconstruction. However, open mesenteric reconstructions continue to play an important role in patients with lesions that are unsuitable for an endovascular option.

Background: Previous analyses suggested that duplex ultrasonography (DUS) detected endoleaks after endovascular aneurysm repair (EVAR) with insufficient sensitivity; they did not specifically examine types 1 and 3 endoleak, which, if untreated, may lead to aneurysm-related death. In light of changes to clinical practice, the diagnostic accuracy of DUS and contrast-enhanced ultrasonography (CEUS) for types 1 and 3 endoleak required focused reappraisal.

Methods: Studies comparing DUS or CEUS with computed tomography (CT) for endoleak detection were identified.
