Objectives: Transcatheter arterial embolisation (TAE) is widely used to treat gastrointestinal bleeding. This paper reports the safety and efficacy of TAE for bleeding following endoscopic resection, including endoscopic mucosal resection and endoscopic submucosal dissection. Methods: Fifteen consecutive patients (13 males, two females; mean age 62.2 years) from two tertiary medical centres who underwent TAE for gastroduodenal bleeding after endoscopic resection from November 2001 to December 2020 were included. Patient demographics, clinical presentations, angiographic findings, and TAE details were retrospectively reviewed. Results: Immediate bleeding during endoscopic resection was noted in four patients. Delayed bleeding 1–30 days after endoscopic resection in nine patients presented with haematochezia (n = 4), haematemesis (n = 6) and melaena (n = 1). Endoscopic haemostasis was attempted in 11 patients (73.3%) but failed due to continued bleeding despite haemostasis (n = 6), failure to secure endoscopic field (n = 3) and unstable vital signs (n = 2). Eleven patients had positive angiographic findings for bleeding, and all bleeding arteries were embolised except one owing to failed superselection of the bleeder. In the other four patients with negative angiographic findings, the left gastric artery with/without the right gastric artery or the accessory left gastric artery was empirically embolised using gelatin sponge particles. Both technical and clinical success rates were 93.3% (14/15). No procedure-related complications occurred during follow-up. Conclusions: TAE is safe and effective in the treatment of immediate and delayed bleeding after endoscopic resection procedures. Advances in knowledge: This is the first and largest 20-year bicentric study published in English on this topic. Empirical TAE for angiographically negative bleeding sites was also effective without significant complications.

Abstract Background It remains unclear whether transcatheter arterial embolisation (TAE) is as safe and effective for paediatric patients with blunt torso trauma as it is for adults in Japan, owing to few trauma cases and sporadic case reports. The study aimed to compare the efficacy and safety of TAE performed in paediatric (age ≤ 15 years) and adult patients with blunt torso trauma. Methods This was a single-centre, retrospective chart review study that included blunt torso trauma patients who underwent TAE in the trauma centre from 2012 to 2017. The comparative study was carried out between a ‘paediatric patient group’ and an ‘adult patient group’. The outcome measures for TAE were the success of haemorrhage control and complications and standardised mortality ratio (SMR). Results A total of 504 patients with blunt torso trauma were transported to the trauma centre, out of which 23% (N = 114) with blunt torso trauma underwent TAE, including 15 paediatric and 99 adult patients. There was no significant difference between the use of TAE in paediatric and adult patients with blunt torso trauma (29% vs 22%, P = .221). The paediatric patients’ median age was 11 years (interquartile ranges 7–14). The predicted mortality rate and SMR for paediatric patients were lower than those for adult patients (18.3% vs 25.9%, P = .026, and 0.37 vs 0.54). The rate of effective haemorrhage control without repeated TAE or additional surgical intervention was 93% in paediatric patients, which was similar to that in adult patients (88%). There were no complications in paediatric patients at our centre. There were no significant differences in the proportion of paediatric patients who underwent surgery before TAE or urgent blood transfusion (33% vs 26%, P = .566, or 67% vs 85%, P = .084). Conclusions It is possible to provide an equal level of care related to TAE for paediatric and adult patients as it relates to TAE for blunt torso trauma with haemorrhage in the trauma centre. Alternative haemorrhage control procedures should be established as soon as possible whenever the patients reach a haemodynamically unstable state.

Abstract Background:Transcatheter arterial embolisation of intercostal vessels is a minimally invasive procedure that is increasingly being used in the management of haemothorax in the trauma patient, however significant complications – such as spinal ischaemia can occur. We present a rare case of paralysis in a patient following embolisation of the intercostal arteries due to bleeding from penetrating trauma.Case presentation:A 46-year-old male presented to the Emergency department with two stab wounds to the right posterior chest. Computed tomography scan of the chest revealed active contrast extravasation from the right 9th intercostal artery. Selective embolisation of the right 9th intercostal artery using Gelfoam® and coils as well as further embolisation of the 7th, 8th and 10th intercostal arteries was performed. Unfortunately due to ongoing bleeding and hypotension, the patient subsequently required emergency surgery that revealed two penetrating injuries to the right inferior lobe of the lung. After the patient was extubated, he was found to have bilateral motor from the level of L4 and below and sensory deficits from L2 and below. Magnetic resonance imaging of the spine showed spinal cord infarction at the level of T11 and T12 that was thought to be secondary to the embolisation of the intercostal arteries inadvertently affecting the artery of Adamkiewicz.Conclusions:Transcatheter arterial embolisation has an established roll in haemostasis of the trauma patient – particularly in intercostal arteries for the management of haemothorax. Although extremely rare, spinal complications from this procedure can be significantly life changing for the patient. The variable anatomy of the artery of Adamkiewicz should be carefully considered on a case-by-base basis in the stable trauma patient and balance of risk versus benefit be determined if the artery is unable to be identified on pre-procedure angiography.
