Abstract
Objectives This study aimed to determine the risk factors associated with the failure of arteriovenous fistulae (AVF) maturation. Methods This retrospective cohort study was conducted from January 2014 to December 2018 in Sultan Qaboos University Hospital, Muscat, Oman. Patients were followed-up 3 months after surgery, and their electronic medical records were accessed for demographic and clinical data. Univariate analysis was used to determine the risk factors associated with early AVF maturation and multivariant analysis was used to determine the predictive factors for AVF failure. Results A total of 269 patients were included. Female gender was a significant factor affecting AVF maturity (P = 0.049), while age (P = 0.626), diabetes (P = 0.954), hypertension (P = 0.378), dyslipidaemia (P = 0.907), coronary artery disease (P = 0.576), cerebrovascular accident (P = 0.864), congestive heart failure (P = 0.685), previous central venous catheterisation (P = 0.05), fistula type (P = 0.863) and fistula site (P = 0.861) did not affect AVF maturation. Binary logistic regression showed that all the risk factors were insignificant. Failure of early AVF maturation affected 11.5% in the cohort. Conclusion This study found that the proportion of early AVF maturation at our hospital is at par with that in the international literature. Failure of AVF maturation was significantly associated with the female gender. These findings can help nephrologists and vascular surgeons prognosticate AVF maturation rates. However, a larger study is needed for definitive conclusions.

Abstract
Blunt thoracic aortic injuries are potentially lethal. Those who survive may form an organised haematoma in the periadventitial space resulting in a pseudoaneurysm, which may be identified incidentally decades later. While the role of thoracic endovascular aortic repair (TEVAR) in acute settings has been established, its role in chronic cases is yet to be defined. We report three cases that were diagnosed incidentally six, nine and 18 years after the injury. Two were managed by TEVAR while the third declined intervention and is on annual follow-up. Patients with asymptomatic and stable pseudoaneurysms of the descending thoracic aorta should be offered surveillance versus TEVAR because the risk of rupture is not negligible, whilst taking into account the patient’s level of physical activity. These three cases highlight the importance of early diagnosis of aortic injuries in blunt trauma and its grading.

Abstract
Objectives This study aimed to discuss the different challenges faced while managing emergency vascular surgery cases during the COVID-19 pandemic and how these challenges were overcome. Methods This study details 14 emergency cases that were managed during a period of one month from mid-March to mid-April at Sultan Qaboos University Hospital, Muscat, Oman. The cases included acute limb ischaemia, critical limb ischaemia, type B dissection of the thoracic aorta, thoraco-abdominal aneurysm, critical internal carotid artery stenosis, trauma, infected arteriovenous forearm loop graft and thrombosed arteriovenous fistulas. Results Only one patient was confirmed to have COVID-19. Five were negative for COVID-19 while the remaining eight were not tested. Various strategies on how the vascular surgical team accommodated changes in hospital protocols and nationwide lockdown are discussed in detail. Conclusions With the judicious use of personal protective equipment and consumable surgical and endovascular devices, communication with support services and other hospitals and implementation of triage protocols, it was possible to manage vascular surgery emergencies effectively.
