We present a case of a middle-aged Caucasian woman who developed acuteon top of chronic limb ischaemia secondary to thrombotic occlusion of a persistent sciatic artery (PSA). Timely investigation and treatment were instituted resulting in a favourable outcome. PSA is an uncommon congenital, developmental, arterial anomaly which can cause serious lower limb complications such as acute or critical limb ischaemia and amputation. As this condition is rarely encountered in regular clinical practice, and has a limb-threatening potential, it is important to be aware of its cause, presentation and management. We describe the embryologic aetiology of PSA and discuss different investigation modalities and treatment options.

Only four early years postgraduate surgical training posts in the UK meet nationally approved minimum quality standards. Specific recommendations are made to improve training in this cohort and to bolster recruitment and retention into Higher Surgical Training.

All animal bites have the potential to cause significant infection. In the UK, dogs are the most common source of bites. Incidence of hospital attendances attributable to dog bites has risen over the last decade. Patient groups at particular risk of bites and/or complications of infection include those at extremes of age, immunosuppressed and patients with diabetes. We report the case of a patient with diabetic peripheral neuropathy, who was admitted on two separate occasions with unprovoked bites to his toes whilst asleep, by his pet dog. He ultimately required terminalisation of the affected digits. Although unusual, this mechanism of injury has been previously described in literature. However, we are unaware of cases reporting multiple separate incidences involving the same patient and animal. We present this case to highlight the perils of untrained pet ownership in diabetic patients with peripheral neuropathy and the importance of prompt medical and surgical treatment of injuries.

Thromboangiitis obliterans (TAO) is a vasculitis characterised by segmental occlusions of small to medium-sized arteries and superficial veins, and a curious predilection for young male smokers. The exact aetiology remains unknown. Current theories postulate it is an autoimmune endarteritis, triggered by some constituent of tobacco and occurring in genetically susceptible individuals. The disease can pose a diagnostic challenge, requiring a high degree of clinical suspicion, particularly in male smokers aged between 20-45 presenting with peripheral ischaemia. The fundamental principle of management is absolute tobacco abstinence. In this article, we report the case of a 27-year-old man who presented with infected, chronic wounds of his upper and lower extremities. He was initially treated with antibiotics and surgical debridement. Unfortunately he went on to develop a protracted course of complications due to poor wound healing ultimately leading to amputation of several digits. A diagnosis of TAO was suspected, and this was later confirmed histologically. Incidentally and of note, the patient was also found to be homozygous for factor V Leiden. An association between TAO and hypercoagulable states, specifically heterozygous factor V Leiden mutation, has been previously described. It is unclear if a synergistic effect between TAO and homozygosity for factor V Leiden may have contributed to the severity and unremitting nature of our patient’s symptoms. We present this case in order to highlight the importance of early recognition of the condition and the need to offer comprehensive smoking cessation support in order to prevent amputation and other complications of poor wound healing.
