Abstract
Internal iliac artery (IIA) balloon occlusion catheters have been commonly inserted to decrease the risk of postpartum hemorrhage in placenta accreta spectrum disorders; however, there has been mixed success in clinical studies. Placement of an infrarenal aortic balloon has shown more consistent effectiveness in recent studies. A possible reason for this is collateral arterial supply to the placenta from external iliac artery branches. Retrospective chart review was conducted of angiography images during prophylactic IIA balloon occlusion catheter insertion over a 7-year period. Sixty-two individual cases were identified. Digital subtraction angiography (DSA) was performed in 32 (52%) cases, and 20 (62%) showed collateral blood supply from branches of the external iliac arteries, namely the round ligament artery. In conclusion, a high proportion of placenta accreta spectrum cases have arterial blood supply from branches of the external iliac artery, which may explain the discrepancy in effectiveness seen between IIA and infrarenal aortic sites of balloon occlusion catheter placement.

Abstract
OBJECTIVES A 2021 safety alert restricted endovascular gelfoam use in Australia and resulted in an embargo on gelfoam sales to IR departments. This study aimed to show that gelfoam is safe in a population of trauma patients with pelvic injury, and discuss the basis of the recent controversies. METHODS Retrospective cohort study between 1 January 2010 and 21 May 2021 of patients who underwent gelfoam embolisation for pelvic arterial haemorrhage. Primary outcome was the rate of adverse events related to intravascular gelfoam administration. RESULTS Inclusion criteria met in 50 patients, comprising 58% males median age 59.9 years, and median injury severity score 31. There were 0 complications related to gelfoam use and 100% technical success. 35 patients (70%) received a non-targeted embolisation approach. All-cause mortality was observed in 5 patients (10%), unrelated to gelfoam. CONCLUSIONS Gelfoam is a safe and effective embolic agent in pelvic trauma. Patients are in urgent need of universal on-label registration of endovascular gelfoam products, as it is life-saving in major haemorrhage after trauma. ADVANCES IN KNOWLEDGE Endovascular gelfoam is mandatory for a high-quality trauma service, and this study shows that it is safe to use intentionally in the endovascular space. Companies should work with interventional radiologists, sharing and collaborating to ensure positive outcomes for patients.

Abstract
BACKGROUND Splenic injury due to colonoscopy is rare, but has high mortality. While historically treated conservatively for low-grade injuries or with splenectomy for high-grade injuries, splenic artery embolisation is increasingly utilised, reflecting modern treatment guidelines for external blunt trauma. This systematic review evaluates outcomes of published cases of splenic injury due to colonoscopy treated with splenic artery embolisation. METHODS A systematic review was performed of published articles concerning splenic injury during colonoscopy treated primarily with splenic artery embolisation, splenectomy, or splenorrhaphy from 1977 to 2022. Datapoints included demographics, past surgical history, indication for colonoscopy, delay to diagnosis, treatment, grade of injury, splenic artery embolisation location, splenic preservation (salvage), and mortality. RESULTS The 30 patients treated with splenic artery embolisation were of mean age 65 (SD 9) years and 67% female, with 83% avoiding splenectomy and 6.7% mortality. Splenic artery embolisation was proximal to the splenic hilum in 81%. The 163 patients treated with splenectomy were of mean age 65 (SD 11) years and 66% female, with 5.5% mortality. Three patients treated with splenorrhaphy of median age 60 (range 59-70) years all avoided splenectomy with no mortality. There was no difference in mortality between splenic artery embolisation and splenectomy cohorts (p = 0.81). CONCLUSIONS Splenic artery embolisation is an effective treatment option in splenic injury due to colonoscopy. Given the known benefits of splenic salvage compared to splenectomy, including preserved immune function against encapsulated organisms, low cost, and shorter hospital length of stay, embolisation should be incorporated into treatment pathways for splenic injury due to colonoscopy in suitable patients.

Abstract
INTRODUCTION Trauma to the pelvic ring and associated haemorrhage represent a management challenge for the multidisciplinary trauma team. In up to 10% of patients, bleeding can be the result of an arterial injury and mortality is reported as high as 89% in this cohort. We aimed to assess the mortality rate after pelvic trauma embolisation and whether earlier embolisation improved mortality. METHODS Retrospective study at single tertiary trauma and referral centre, between 1 January 2009 and 30 June 2022. All adult patients who received embolisation following pelvic trauma were included. Patients were excluded if angiography was performed but no embolisation performed. RESULTS During the 13.5-year time period, 175 patients underwent angiography and 28 were excluded, leaving 147 patients in the study. The all-cause mortality rate at 30-days was 11.6% (17 patients). The median time from injury to embolisation was 6.3 h (range 2.8-418.4). On regression analysis, time from injury to embolisation was not associated with mortality (OR 1.01, 95% CI 0.952-1.061). Increasing age (OR 1.20, 95% CI 1.084-1.333) and increasing injury severity score (OR 1.14, 95% CI 1.049-1.247) were positively associated with all-cause 30-day mortality, while non-selective embolisation (OR 0.11, 95% CI 0.013-0.893) was negatively associated. CONCLUSION The all-cause mortality rate at 30-days in or cohort was very low. In addition, earlier time from injury to embolisation was not positively associated with all-cause 30-day mortality. Nevertheless, minimising this remains a fundamental principle of the management of bleeding in pelvic trauma.

Abstract
ABSTRACT Diffusion magnetic resonance imaging tractography is a noninvasive technique that enables the visualization and quantification of white matter tracts within the brain. It is extensively used in preoperative planning for brain tumors, epilepsy, and functional neurosurgical procedures such as deep brain stimulation. Over the past 25 years, significant advancements have been made in imaging acquisition, fiber direction estimation, and tracking methods, resulting in considerable improvements in tractography accuracy. The technique enables the mapping of functionally critical pathways around surgical sites to avoid permanent functional disability. When the limitations are adequately acknowledged and considered, tractography can serve as a valuable tool to safeguard critical white matter tracts and provides insight regarding changes in normal white matter and structural connectivity of the whole brain beyond local lesions. In functional neurosurgical procedures such as deep brain stimulation, it plays a significant role in optimizing stimulation sites and parameters to maximize therapeutic efficacy and can be used as a direct target for therapy. These insights can aid in patient risk stratification and prognosis. This article aims to discuss state-of-the-art tractography methodologies and their applications in preoperative planning and highlight the challenges and new prospects for the use of tractography in daily clinical practice.

Abstract
OBJECTIVES Atraumatic needles are known to reduce complication rates of blind lumbar punctures (LP), however, their use in fluoroscopically guided LP is less studied. This study assessed the comparative difficulty of performing fluoroscopic lumbar puncture with atraumatic needles. METHODS Single-centre retrospective case-control study comparing atraumatic and conventional or 'cutting' needles using fluoroscopic time and radiation dose (Dose Area Product or DAP) as surrogate markers. Patients were assessed from two comparable eight-month periods before and after a policy change to primary use of atraumatic needles. RESULTS 105 procedures with a cutting needle were performed in the group prior to the policy change. Median fluoroscopy time was 48 sec and median DAP was 3.14. Of 102 procedures performed in the group after the policy change, 99 were performed with an atraumatic needle and three with a cutting needle after initial attempt with an atraumatic needle. Median fluoroscopy time was 41 sec and median DAP was 3.28. The mean number of attempts was 1.02 in the cutting needle group and 1.05 in the atraumatic needle group. There was no significant difference in median fluoroscopy time, median DAP, or mean number of attempts. CONCLUSION Fluoroscopic screening time, DAP and mean number of attempts were not significantly increased with primary use of atraumatic needles for LP. Use of atraumatic needles should be considered in fluoroscopic LP given the lower complication rates. ADVANCES IN KNOWLEDGE This study provides new data showing that the use of atraumatic needles does not increase the difficulty of fluoroscopically guided LP.

Abstract
AIM To clarify manufacturer's instructions for inferior vena cava (IVC) filter use and implications for practice. MATERIALS AND METHODS Three vendors of IVC filters were contacted for clarification, with all stating that caval diameter limits are to be true maximum and true minimum cross-sectional diameters. To determine the implications of this, measurements were performed on 302 abdominal computed tomography studies in four transaxial dimensions perpendicular to the long axis including true maximum and minimum diameters, and measurements reflecting those typically taken on fluoroscopic cavography. RESULTS Based on the true maximum and true minimum caval diameter limits as clarified by vendors, 22% of patients who would typically be considered suitable for IVC filter insertion based on frontal and lateral fluoroscopic cavography would be contraindicated, and 40% of patients who would typically be considered suitable for IVC filter insertion based on only frontal fluoroscopic cavography (as lateral projection is often not performed) would be contraindicated. CONCLUSION There is a marked discordance between the vendor-clarified caval diameter limits of three common IVC filter devices and real-world caval geometry. Given the rarity of complications, this suggests a pressing need for revision of manufacturers' instructions for use statements to better reflect current safe routine clinical use, particularly from a medicolegal perspective.

Abstract
PURPOSE To assess the efficacy of conservative management and embolisation in patients with spontaneous retroperitoneal haemorrhage. METHODS Single-centre retrospective case-control study of patients with spontaneous retroperitoneal haemorrhage treated conservatively or with embolisation. Patients aged ≥ 18 years were identified from CT imaging reports stating a diagnosis of retroperitoneal haemorrhage or similar and images reviewed for confirmation. Exclusion criteria included recent trauma, surgery, retroperitoneal vascular line insertion, or other non-spontaneous aetiology. Datapoints analysed included treatment approach (conservative or embolisation), technical success, clinical success, and mortality outcome. RESULTS A total of 54 patients met inclusion criteria, who were predominantly anticoagulated (74%), male (72%), older adults (mean age 69 years), with active haemorrhage on CT (52%). Overall mortality was 15%. Clinical success was more likely with conservative management (36/38) than embolisation (9/16; p < 0.01), and all-cause (1/38 vs 7/16; p < 0.01) and uncontrolled primary bleeding (1/38 vs 5/16; p < 0.01) mortality were higher with embolisation. However, embolised patients more commonly had active bleeding on CT (15/38 vs 13/16; p < 0.01), shock (5/38 vs 6/16; p < 0.04), and higher blood transfusion volumes (mean 2.2 vs 5.9 units; p < 0.01). After one-to-one propensity score matching, differences in clinical success (p = 0.04) and all-cause mortality (p = 0.01) remained; however, difference in uncontrolled primary bleeding mortality did not (p = 0.07). CONCLUSION Conservative management of SRH is likely to be effective in most patients, even in those who are anticoagulated and haemodynamically unstable, with variable success seen after embolisation in a more unstable patient group, supporting the notion that resuscitation and optimisation of coagulation are the most vital components of treatment.

Abstract
BACKGROUND Inferior vena cava (IVC) filters play a role in preventing venous thromboembolism after major trauma where deep venous thrombosis (DVT) risk is up to 80%. It has been suggested that IVC filters are thrombogenic and many patients are therefore placed on therapeutic anticoagulation during IVC filter dwell citing concern of in situ IVC thrombosis, even in the absence of existing DVT. METHODS Between 1 June 2018 and 31 December 2021, this retrospective study assessed the incidence of IVC thrombosis following prophylactic IVC filter insertion. Groups were defined according to the presence or absence of therapeutic anticoagulation during filter dwell. The primary outcome was the presence or absence of IVC thrombus at retrieval. RESULTS A total of 124 patients were included. Anticoagulation was prescribed in 29 and anticoagulation was not prescribed in 63. A further 32 patients developed a new thrombosis episode after the prophylactic IVC filter was placed, and 29 were prescribed anticoagulation part-way during filter dwell as a result of this diagnosis. No cases of IVC occlusion were observed in any patient group. CONCLUSIONS Caval thrombosis was not observed after prophylactic filter placement, with or without the prescription of anticoagulation. While prospective trials are needed to increase the level of evidence, based on these results the use of therapeutic anticoagulation during IVC filter dwell should not be dictated by the presence of an IVC filter alone but rather by the presence of a related thrombosis event.

Abstract
Uterine artery embolisation (UAE) is a safe and effective procedure for symptomatic uterine fibroids with an estimated rate of post-operative intra-uterine infection of 0.9-2.5%. While rates of infection have remained low over the past two decades, there is variation in infection prevention practices. Intra-uterine infection after UAE may occur via access site haematogenous spread or ascension of vaginal flora through the cervical canal. Although the evidence base is immature, risk factors for infection including previous pelvic infection, hydrosalpinx, endocervical incompetence, diabetes, smoking, obesity, respiratory disease, and immunosuppression should be assessed during the pre-operative consultation with the interventional radiologist to tailor a plan for minimising infection, which may include optimisation of any modifiable risk facts and prophylactic antibiotics.

Abstract
OBJECTIVES To provide an illustrative description of the technique and spectrum of findings in defecating proctography. KEY FINDINGS Important findings on defecating proctography include rectocoele, enterocoele, sigmoidocoele, cystocoele, intussusception, rectal prolapse, descending perineum, incomplete emptying, anismus, and faecal incontinence. This review article illustrates these key findings with examples. CONCLUSION Defecating proctography is a well-established and cost-effective method of assessing disordered defecation. In conjunction with clinical information and other diagnostic tests, findings on defecating proctography can guide appropriate multidisciplinary management and may lead to improvement in embarrassing and debilitating symptoms in many patients. IMPLICATIONS FOR PRACTICE This review article provides a suggested technique and covers the spectrum of findings on defecating proctography.

Abstract
Splenic artery embolization (SAE) plays a critical role in the treatment of high-grade splenic injury not requiring emergent laparotomy. SAE preserves splenic tissue, and growing evidence demonstrates preserved short-term splenic immune function after SAE. However, long-term function is less studied. Patients who underwent SAE for blunt abdominal trauma over a 10-year period were contacted for long-term follow-up. Sixteen participants (sex: women, 10, and men, 6; age: median, 34 years, and range, 18-67 years) were followed up at a median of 7.7 years (range, 4.7-12.8 years) after embolization. Splenic lacerations were of American Association for the Surgery of Trauma grades III to V, and 14 procedures involved proximal embolization. All individuals had measurable levels of IgM memory B cells (median, 14.30 as %B cells), splenic tissue present on ultrasound (median, 122 mL), and no history of severe infection since SAE. In conclusion, this study quantitatively demonstrated that long-term immune function remains after SAE for blunt abdominal trauma based on the IgM memory B cell levels.

Abstract
The spleen is the most commonly injured solid organ following blunt abdominal trauma. Over recent decades, splenic artery embolization (SAE) has become the mainstay treatment for haemodynamically stable patients with high-grade blunt splenic trauma, with splenectomy the mainstay of treatment for unstable patients. Splenic function is complex but the spleen has an important role in immune function, particularly in protection against encapsulated bacteria. Established evidence suggests that following splenectomy immune function is impaired resulting in increased susceptibility to overwhelming post-splenectomy infection, however, immune function may be preserved following SAE. This review will discuss the current state of the literature on immune function following different treatments of blunt splenic injury, and the controversies surrounding what constitutes a quantitative test of splenic immune function.

Abstract
In athletes, long‐term intensive training has been shown to increase unparalleled athletic ability and might induce brain plasticity. We evaluated the structural connectome of world‐class gymnasts (WCGs), as mapped by diffusion‐weighted magnetic resonance imaging probabilistic tractography and a multishell, multitissue constrained spherical deconvolution method to increase the precision of tractography at the tissue interfaces. The connectome was mapped in 10 Japanese male WCGs and in 10 age‐matched male controls. Network‐based statistic identified subnetworks with increased connectivity density in WCGs, involving the sensorimotor, default mode, attentional, visual, and limbic areas. It also revealed a significant association between the structural connectivity of some brain structures with functions closely related to the gymnastic skills and the D‐score, which is used as an index of the gymnasts' specific physical abilities for each apparatus. Furthermore, graph theory analysis demonstrated the characteristics of brain anatomical topology in the WCGs. They displayed significantly increased global connectivity strength with decreased characteristic path length at the global level and higher nodal strength and degree in the sensorimotor, default mode, attention, and limbic/subcortical areas at the local level as compared with controls. Together, these findings extend the current understanding of neural mechanisms that distinguish WCGs from controls and suggest brain anatomical network plasticity in WCGs resulting from long‐term intensive training. Future studies should assess the contribution of genetic or early‐life environmental factors in the brain network organization of WCGs. Furthermore, the indices of brain topology (i.e., connection density and graph theory indices) could become markers for the objective evaluation of gymnastic performance.

Abstract
There has been an increasing prevalence of neurodegenerative diseases with the rapid increase in aging societies worldwide. Biomarkers that can be used to detect pathological changes before the development of severe neuronal loss and consequently facilitate early intervention with disease-modifying therapeutic modalities are therefore urgently needed. Diffusion magnetic resonance imaging (MRI) is a promising tool that can be used to infer microstructural characteristics of the brain, such as microstructural integrity and complexity, as well as axonal density, order, and myelination, through the utilization of water molecules that are diffused within the tissue, with displacement at the micron scale. Diffusion tensor imaging is the most commonly used diffusion MRI technique to assess the pathophysiology of neurodegenerative diseases. However, diffusion tensor imaging has several limitations, and new technologies, including neurite orientation dispersion and density imaging, diffusion kurtosis imaging, and free-water imaging, have been recently developed as approaches to overcome these constraints. This review provides an overview of these technologies and their potential as biomarkers for the early diagnosis and disease progression of major neurodegenerative diseases.

Abstract
Kaposi Sarcoma (KS), a mucocutaneous cancer that most frequently occurs in the context of Acquired Immunodeficiency Syndrome (AIDS) secondary to Human Immunodeficiency Virus (HIV), is a relatively benign condition, acting more as a marker of immunodeficiency than directly causing harm itself. However, it has been known to spread both locally and in a metastatic fashion, with reports of KS affecting almost all organ systems. One of the most rarely reported areas of involvement is the musculoskeletal system, with secondary osseous spread representing an even smaller subset of these. We report a case of biopsy proven disseminated intraosseous KS involving the entire imaged skeleton that occurred with HIV/AIDS, despite maximal treatment and normal imaging 8 months prior.

Abstract
OBJECTIVE We evaluated the influence of the renin-angiotensin system (RAS) on intestinal inflammation and fibrosis. DESIGN Cultured human colonic myofibroblast proliferation and collagen secretion were assessed following treatment with angiotensin (Ang) II and Ang (1-7), their receptor antagonists candesartan and A779, and the ACE inhibitor captopril. Circulating and intestinal RAS components were evaluated in patients with and without IBD. Disease outcomes in patients with IBD treated with ACE inhibitors and angiotensin receptor blockers (ARBs) were assessed in retrospective studies. RESULTS Human colonic myofibroblast proliferation was reduced by Ang (1-7) in a dose-dependent manner (p<0.05). Ang II marginally but not significantly increased proliferation, an effect reversed by candesartan (p<0.001). Colonic myofibroblast collagen secretion was reduced by Ang (1-7) (p<0.05) and captopril (p<0.001), and was increased by Ang II (p<0.001). Patients with IBD had higher circulating renin (mean 25.4 vs 18.6 mIU/L, p=0.026) and ACE2:ACE ratio (mean 0.92 vs 0.69, p=0.015) than controls without IBD. RAS gene transcripts and peptides were identified in healthy and diseased bowels. Colonic mucosal Masson's trichrome staining correlated with Ang II (r=0.346, p=0.010) and inversely with ACE2 activity (r=-0.373, p=0.006). Patients with IBD who required surgery (1/37 vs 12/75, p=0.034) and hospitalisation (0/34 vs 8/68, p=0.049) over 2 years were less often treated with ACE inhibitors and ARBs than patients not requiring surgery or hospitalisation. CONCLUSIONS The RAS mediates fibrosis in human cell cultures, is expressed in the intestine and perturbed in intestinal inflammation, and agents targeting this system are associated with improved disease outcomes.

Abstract
Segmental arterial mediolysis (SAM) is a rare, non-inflammatory, vascular condition that predominantly affects medium-sized to large-sized abdominal arteries and can present with haemorrhage into the abdominal cavity. We report the case of a patient with SAM of the coeliac, splenic, renal and gastroduodenal arteries in whom endovascular coil embolisation was successfully used to treat a bleeding gastroduodenal artery pseudoaneurysm.
