Surfer's myelopathy was first described by Thompson et al., in 2004.1 It is a rare cause of sudden spinal cord injury that occurs in the absence of direct trauma to the spinal area in novice healthy surfers. We present the case of the youngest patient we are aware of to be diagnosed with surfer's myelopathy following actual surfing. A clear aetiology for surfer's myelopathy has not previous been described. However, the hypothesis that there is ischaemia to the lower spinal cord is supported by our case, where we present the first clear angiographic evidence of the occlusion of the great anterior radicular artery of Adamkiewicz in a patient diagnosed with surfer's myelopathy...

Spinal cord injury (SCI) possesses a significant health and economic burden worldwide. Traumatic SCI is a devastating condition that evolves through two successive stages. Throughout each of these stages, disturbances in ionic homeostasis, local oedema, ischaemia, focal haemorrhage, free radicals stress and inflammatory response were observed. Although there are no fully restorative cures available for SCI patients, various molecular, cellular and rehabilitative therapies, such as limiting local inflammation, preventing secondary cell death and enhancing the plasticity of local circuits in the spinal cord, were described...

OBJECTIVES: Despite research into protective pharmacological adjuncts, paraplegia persists as a dreaded complication after thoracic and thoracoabdominal aortic interventions. Reports on gender-related neurological outcomes after ischaemic and traumatic brain injuries have led to increased interest in hormonal neuroprotective effects and have generated other studies seeking to prove the neuroprotective effects of the therapeutic administration of 17β-oestradiol and of progesterone. We hypothesised that acute administration of oestradiol or progesterone would prevent or attenuate spinal cord ischaemic injury induced by occlusion of the descending thoracic aorta...

OBJECTIVES: Thoracic endovascular aortic repair (TEVAR) is used for treatment of thoracic aortic pathologies, but the covered stent graft can induce spinal ischaemia depending on the length used. The left subclavian artery contributes to spinal cord collateralization and is frequently occluded by the stent graft. Our objective was to investigate the impact of covered stent graft length on the risk of spinal ischaemia in the setting of left subclavian artery sacrifice. METHODS: Twenty-six pigs (German country race, mean body weight 36 ± 4 kg) underwent simulated descending aortic TEVAR via left lateral thoracotomy, with left subclavian artery and thoracic segmental artery occlusion in normothermia...

PURPOSE: Preservation of intercostal arteries during thoracic aortic procedures reduces the risk of post-operative paraparesis. The origins of the intercostal arteries are visible on pre-operative computed tomography angiography (CTA), but rarely on intra-operative angiography. The purpose of this report is to suggest an image fusion technique for intra-operative localisation of the intercostal arteries during thoracic endovascular repair (TEVAR). TECHNIQUE: The ostia of the intercostal arteries are identified and manually marked with rings on the pre-operative CTA...

BACKGROUND: An abdominal aortic aneurysm (AAA) (pathological enlargement of the aorta) is a condition that can occur as a person ages. It is most commonly seen in men older than 65 years of age. Progressive aneurysm enlargement can lead to rupture and massive internal bleeding, which is fatal unless timely repair can be achieved. Despite improvements in perioperative care, mortality remains high (approximately 50%) after conventional open surgical repair. Endovascular aneurysm repair (EVAR), a minimally invasive technique, has been shown to reduce early morbidity and mortality as compared to conventional open surgery for planned AAA repair...

BACKGROUND: Prophylactic open surgery is the standard practice in patients with connective tissue and thoracoabdominal aortic aneurysm (TAAA) and aortic arch disease. Branched and fenestrated devices offer a less invasive alternative but there are concerns regarding the durability of the repair and the effect of the stent graft on the fragile aortic wall. The aim of this study is to evaluate mid-term outcomes of fenestrated and/or branched endografting in patients with connective tissue disease...

We report the case of a patient who developed paraparesis 2 days after endovascular aneurysm repair for a right common iliac aneurysm. The patient had undergone thoracic endovascular aortic repair. The left subclavian artery was occluded, but the left internal iliac artery was preserved. The patient fully recovered from the paralysis within 3 months. This case illustrates the importance of collateral blood supply to the spinal cord from the lumbosacral region, especially when other sources are occluded.

Spinal anaesthesia is the most preffered anesthesia technique for total hip replacement, and its complications range from low entity (insignificant) to life threatening. The incidence of neurologic complications after neuraxial anaesthesia is not perfectly clear, although there are several described cases of spinal cord ischaemia. We present a case of unilateral T8-T11 spinal cord ischaemia following L2-L3 spinal anaesthesia for total hip replacement. Magnetic resonance imaging showed a hyperintense T8-T11 signal alteration on the leftside of paramedian spinal cord...

Ischaemic postconditioning (IPostC) was introduced for the first time by Zhao et al. as a feasible method for reduction of myocardial ischaemia-reperfusion (IR) injury. The cardioprotection by this protocol has been extensively evaluated in various species. Then, further research revealed that IPostC is a safe and convenient approach in limiting IR injury of non-myocardial tissues such as lung, liver, kidney, intestine, skeletal muscle, brain and spinal cord. IPostC has been conducted with different algorithms, resulting in diverse effects...

Stroke is a significant cause of death and disability in Singapore; in 2014, it was the fourth most common cause of death. Transient ischaemic attack (TIA) is defined as a transient episode of neurological dysfunction caused by focal brain, spinal cord or retinal ischaemia without evidence of acute infarction. The diagnosis of TIA/acute stroke needs to be considered in all patients who present with sudden focal neurological dysfunction. Prompt referral for assessment, neuroimaging and intervention provides the best chance for neurological recovery and/or minimising further neurological damage...

Acute spinal cord injury (SCI) has become epidemic in modern society. Despite advances made in the understanding of the pathogenesis and improvements in early recognition and treatment, it remains a devastating event, often producing severe and permanent disability. SCI has two phases: acute and secondary. Although the acute phase is marked by severe local and systemic events such as tissue contusion, ischaemia, haemorrhage and vascular damage, the outcome of SCI are mainly influenced by the secondary phase...

OBJECTIVES: Aortic coarctation presenting during adult life most frequently represents cases of re-coarctation, following previous transcatheter or surgical therapy, or missed cases of native coarctation. In the area of evolving endovascular therapy, we believe that there is still a place for durable open repair by means of resection and interposition grafting. We, therefore, evaluated our results in adult patients with primary aortic coarctation or complications of a previous coarctation repair...
