- Internal thoracic artery (ITA) aneurysms are rare, but a rupture is potentially fatal. Most cases of ITA aneurysms are iatrogenic, caused by, for instance, previous sternotomy or pacemaker implantation. Other known aetiologies are vasculopathies, either of inflammatory origin or as part of connective tissue disorders like Marfan's syndrome, Ehler-Dahnlos syndrome or neurofibromatosis Type 1. Idiopathic ITA aneurysms are exceedingly scarce. The present case illustrates an unusual scenario, which posed diagnostic challenges, where spontaneous rupture of an idiopathic or possibly very late post-traumatic aneurysm of the left ITA led to a life-threatening bleeding, successfully treated by endovascular coiling with standby preparation for conversion to open surgery. This case demonstrates the importance of the careful interpretation of radiological findings and the significance of multidisciplinary collaboration between radiologist and clinician.

- INTRODUCTION: Hepatocellular carcinoma (HCC) is a common cause of cancer-related death, often detected in the intermediate stage. The standard of care for intermediate-stage HCC is transarterial chemoembolisation (TACE), where idarubicin (IDA) is a promising drug. Despite the fact that TACE has been used for several decades, treatment success is unpredictable. This clinical trial has been designed believing that further improvement might be achieved by increasing the understanding of interactions between local pharmacology, tumour targeting, HCC pathophysiology, metabolomics and molecular mechanisms of drug resistance.METHODS AND ANALYSIS: The study population of this single-centre clinical trial consists of adults with intermediate-stage HCC. Each tumour site will receive TACE with two different IDA doses, 10 and 15 mg, on separate occasions. Before and after each patient's first TACE blood samples, tissue and liquid biopsies, and positron emission tomography (PET)/MRI will be performed. Blood samples will be used for pharmacokinetics (PK) and liver function evaluation. Tissue biopsies will be used for histopathology analyses, and culturing of primary organoids of tumour and non-tumour tissue to measure cell viability, drug response, multiomics and gene expression. Multiomics analyses will also be performed on liquid biopsies. PET/MRI will be used to evaluate tumour viability and liver metabolism. The two doses of IDA will be compared regarding PK, antitumour effects and safety. Imaging, molecular biology and multiomics data will be used to identify HCC phenotypes and their relation to drug uptake and metabolism, treatment response and survival.ETHICS AND DISSEMINATION: Participants give informed consent. Personal data are deidentified. A patient will be withdrawn from the study if considered medically necessary, or if it is the wish of the patient. The study has been approved by the Swedish Ethical Review Authority (Dnr. 2021-01928) and by the Medical Product Agency, Uppsala, Sweden.TRIAL REGISTRATION NUMBER: EudraCT number: 2021-001257-31.

Magnetic resonance imaging of sacroiliac joint inflammation

- A consecutive series of 27 patients with symptoms compatible with sacroiliitis underwent magnetic resonance imaging (MRI) of the sacroiliac joints. The diagnostic sensitivity of MRI was similar to that of computed tomography or conventional radiography. However, MRI seems to have the potential of providing unique information about the disease process in sacroiliitis by demonstrating abnormalities in subchondral bone and periarticular bone marrow. The results of this study suggest that early inflammatory changes in sacroiliitis occur in the subchondral structures of the sacroiliac joints.

- Several studies have been published on disc degeneration among young athletes in sports with great demands on the back, but few on competitive divers; however, there are no long-term follow-up studies. Twenty elite divers between 10 and 21 years of age, with the highest possible national ranking, were selected at random without knowledge of previous or present back injuries or symptoms for an MRI study of the thoraco-lumbar spine in a 5-year longitudinal study. The occurrence of MRI abnormalities and their correlation with back pain were evaluated. Eighty-nine percent of the divers had a history of back pain and the median age at the first episode of back pain was 15 years. Sixty-five percent of the divers had MRI abnormalities in the thoraco-lumbar spine already at baseline. Only one diver without abnormalities at baseline had developed abnormalities at follow-up. Deterioration of any type of abnormality was found in 9 of 17 (53%) divers. Including all disc levels in all divers, the total number of abnormalities increased by 29% at follow-up, as compared to baseline. The most common abnormalities were reduced disc signal, Schmorl's nodes, and disc height reduction. Since almost all divers had previous or present back pain, a differentiated analysis of the relationship between pain and MRI findings was not possible. However, the high frequency of both back pain and MRI changes suggests a causal relationship. In conclusion, elite divers had high frequency of back pain at young ages and they run a high risk of developing degenerative abnormalities of the thoraco-lumbar spine, probably due to injuries to the spine during the growth spurt.

- A total 71 male athletes (weight lifters, wrestlers, orienteers, and ice-hockey players) and 21 non-athletes were randomly selected, for a baseline MRI study. After 15 years all the participants at baseline were invited to take part in a follow-up examination, including a questionnaire on back pain and a follow-up MRI examination. Thirty-two athletes and all non-athletes had disc height reduction at one or several disc levels. Disc degeneration was found in more than 90% of the athletes and deterioration had occurred in 88% of the athletes, with the highest frequency in weight lifters and ice-hockey players. 78% of the athletes and 38% of the non-athletes reported previous or present history of back pain at baseline and 71 and 75%, respectively at follow-up. There was no statistically significant correlation between back pain and MRI changes. In conclusion, athletes in sports with severe or moderate demands on the back run a high risk of developing disc degeneration and other abnormalities of the spine on MRI and they report high frequency of back pain. The study confirmed our hypothesis, i.e. that most of the spinal abnormalities in athletes seem to occur during the growth spurt, since the majority of the abnormalities demonstrated at follow-up MRI after the sports career were present already at baseline. The abnormalities found at young age deteriorated to a varying degree during the 15-year follow-up, probably due to a combination of continued high load sporting activities and normal ageing. Preventive measures should be considered to avoid the development of these injuries in young athletes.

- PURPOSE: To evaluate the collective incidence of, and experience with, aortoenteric fistula after endovascular aortoiliac therapy. MATERIALS AND METHODS: A systematic literature research was performed to identify cases of aortoenteric fistulation after aortic stent-graft procedures or stent implantation. RESULTS: The review revealed 16 cases of aortoenteric fistulation after aortic stent-grafting (n = 15) or stent placement (n = 1), in 14 patients with abdominal aortic aneurysm. Six had undergone endovascular aneurysm repair because of what was considered a "hostile abdomen." The symptoms did not differ from those in patients with arterioenteric fistulation after open aortic repair. A defect in the stent-graft or its function was the predominant cause of fistulation. One fistula was diagnosed at autopsy, two patients died perioperatively, and 13 survived with in situ repair or an axillobifemoral graft, all after removal of the stent-graft or stent. However, the follow-up time was short, longer than 1 year in only five of the 13 survivors. CONCLUSIONS: Aortoenteric fistulation does occur after endovascular implantation of stents and stent-grafts. The incidence is unknown but is probably low. Follow-up time in most publications was less than 1 year, which is considered short to assess potential graft infection.

- Difficult-to-control intraoperative bleeding--practical measures Bleeding with difficulties obtaining haemostasis can be a catastrophe. This paper summarizes a symposium with the above title. A short introduction gives the background of normal haemostasis as well as iatrogenic vascular injuries as reflected in the Swedish vascular registry (Swedvasc). Practical guidelines are given on how to manage situations of severe haemorrhage with the help of pharmacological substances, local haemostatics, endovascular methodology and open surgery.
