RESUMO
Reinforced cementoplasty with spindles is a recently introduced technique that is mainly used for pathological fractures or for bone metastases at risk of fracture in locations with shear stresses. The technique is less challenging to perform than percutaneous screw insertion and does not require equipment sterilization. No general anesthetic is required. A small trocar is all that is needed, and sutures are often unnecessary. Reinforced cementoplasty can therefore be considered as a technical evolution of cementoplasty with the simple addition of material within the trocar. This technique deserves more awareness so that it can be included in interventional radiologists' range of procedures.

PURPOSE: The aim of this prospective study was to evaluate the tolerance and feasibility of using virtual reality headsets with patients during interventional radiology procedures. MATERIAL AND METHOD: In this single-center prospective study, the use of a virtual reality headset in addition to the usual analgesic and anxiolytic treatment was proposed to all patients presenting in the interventional radiology department from December 2020 to June 2022. Exclusion criteria were as follows: (1) patients with whom it was not possible to communicate (2) epileptic patients, (3) non-verbal patients, and (4) pregnant women. The main objective was to evaluate the safety of the procedure by screening complications during and after the procedure. The second objective was to evaluate feasibility, as defined by the number of patients using the helmet until the end of the procedure. Effectiveness (patient's self-evaluation of pain and anxiety), comfort, satisfaction, emotions felt, sense of security, and feeling of immersion were also evaluated. Caregivers completed a feedback questionnaire. RESULTS: Virtual reality headsets were offered to 100 patients, 9 of whom declined. Procedures were achieved in 93.5% of cases: 6/91 patients removed the headset before the end of the procedure. There were minor adverse events in 2/85 (2.3%) procedures (discomfort and nausea) and no major adverse events. 93.9% of patients found an overall benefit, and 90.2% would recommend virtual reality to another patient. 94.4% of caregivers were satisfied with the virtual reality equipment. The mean pain level was 2.5 ± 2.7 before the procedure, 3.3 ± 2.5 during the procedure, and 1.6 ± 2.7 after the procedure. Mean anxiety scores were 4.6 ± 2.9 before the procedure, 3.1 ± 2.7 during the procedure, and 1.1 ± 1.9 after the procedure. CONCLUSION: The use of virtual reality technology as a complement to traditional therapy for procedures under local anesthesia is feasible and safe in interventional radiology and can be beneficial for pain and anxiety management.

OBJECTIVES: Inferior vena cava filter (IVCF) placement is indicated when there is a deep vein thrombosis and/or a pulmonary embolism and a contraindication of anticoagulation. Due to the increased risk of recurrent deep venous thrombosis when left in place, IVCF removal is indicated once anticoagulant treatment can be reintroduced. However, many temporary IVCF are not removed. We aimed to analyze the removal rate and predictors of filter non-removal in a university hospital setting. METHODS: We collected all the data of consecutive patients who had a retrievable IVCF inserted at the Saint-Etienne University Hospital (France) between April 2012 and November 2019. Rates of filter removal were calculated. We analyzed patient characteristics to assess factors associated with filter non-removal, particularly in patients without a definitive filter indication. The exclusion of this last category of patients allowed us to calculate an adjusted removal rate. RESULTS: The overall removal rate of IVCF was 40.5% (IC 95% 35.6-45.6), and the adjusted removal rate was 62.9 % (IC 95% 56.6-69.2%). No major complications were noted. Advanced age (p < 0.0001) and cancer presence (p < 0.003) were statistically significant predictors of patients not being requested to make a removal attempt. CONCLUSIONS: Although most of the filters placed are for therapeutic indications validated by scientific societies, the removal rate in this setting remains suboptimal. The major factors influencing IVCF removal rate are advanced age and cancer presence. KEY POINTS: ⢠Most vena cava filters are placed for therapeutic indications validated by scientific societies. ⢠Vena cava filter removal rates in this setting remain suboptimal. ⢠Major factors influencing IVCF removal rate are advanced age and cancer presence.

BACKGROUND: Nocardia cyriacigeorgica is one of the most common Nocardia species found in human infections, recently reclassified. Even though Nocardia may affect all organs by hematogenous dissemination, bacteremia are uncommon. Among all possible dissemination sites, the involvement of the adrenal glands is particularly rare. CASE PRESENTATION: We report here a rare case of Nocardia disseminated infection with notably bacteremia and adrenal gland abscess, in a 77-years-old immunocompetent man. Adrenal gland abscess diagnosis was made by imaging (computerized tomography, magnetic resonance and positron emission tomography scan). A complete regression of all lesions including the left adrenal gland was obtained after 6 months of antibiotics. A review of literature was also performed. CONCLUSION: Nocardia bacteremia is a rare event but blood cultures may help to improve detection of Nocardia spp. in a non-invasive way. Adrenal abscess due to Nocardia spp. is very rare with only fourteen cases reported in the literature, but it is a true cause of adrenal masses. Our report suggests that clinician should be aware of this rare location and prioritize a non-invasive diagnosis strategy.

INTRODUCTION: The objective was to compare the two-year ultrasonographic outcomes in a consecutive series of patients with acute Achilles tendon rupture (ATr), either treated surgically or nonoperatively. MATERIALS AND METHODS: This is a prospective, single-center, consecutive series. All patients presenting with acute ATr were included and divided into two groups: surgical or nonoperative groups. At two years, patients were evaluated clinically and sonographically. The parameters studied were length of the tendon on the rupture side (LTCR) and on the contralateral side (LTCS), ratio LTCR/LTCS, maximum anteroposterior diameter on the rupture side (DAPMR), maximum surface area on the rupture side (SMR), maximum anteroposterior diameter on the contralateral side (DAPMS), and maximum surface area on the contralateral side (SMS). Morphological changes in tendon structure were reported. RESULTS: Thirty patients were included. No difference in functional score was observed between both groups. In the nonoperative group, there is a significant difference between: LTCR and LTCS; DAPMR and DAPMS. In the surgical group, there is a significant difference between: LTCR and LTCS; DAPMR and DAPMS; SMR and SMS. There is a significant difference when comparing SMR/SMS between both groups. In terms of morphological changes in tendon structure, there were differences. CONCLUSION: At two years, there was no difference in functional outcomes between the two groups. In both groups, AT were lengthened and thickened without differences between groups. There was a significant difference when comparing the ratio SMR/SMS between groups. Ultrasound examination demonstrated different morphological changes in tendon structure depending on the treatment performed.

We report a rare case of Staphylococcus argenteus bone and joint infection in a 9-year-old boy in France. His finger arthritis was complicated by osteitis 5 weeks later, which resulted in a secondary intervention. This case indicates the virulence of S. argenteus, an emerging pathogen whose clinical effects are poorly described.

BACKGROUND: The migration of contraceptive devices into pulmonary arteries is extremely rare, reported to be 1 in 100,000. CASE PRESENTATION: A 19-year-old female presented no sensation of a contraceptive implant in her arm which had been placed one year prior. A CT scan confirmed that the implant had migrated into the left lower segmentary pulmonary artery. After a multidisciplinary meeting, an endovascular approach was attempted. Following right femoral venous access, a 8F NeuronMax® introducer was placed into the left pulmonary artery under fluoroscopic guidance. The contraceptive device was removed using a 25-mm loop snare, with a proximal capture technique. The patient was discharged the following day, with no reported complications. CONCLUSION: In cases of contraceptive device migration, the first medical decision involves deciding between removal or 'watching and waiting'. Previous reports describe two removal options: endovascular or surgical approaches. Fourteen reports have been published, with high technical success and low rates of complications. The loop snare technique is described as the optimal technique for an endovascular approach. Due to their invasive nature, surgical approaches should be reserved for cases of endovascular removal failure, after evaluating risks and benefits.
RESUMO
PURPOSE: To assess effectiveness on pain, quality of life and late adverse events of percutaneous fixation with internal cemented screw (FICS) among patients with iliac lytic bone metastases with or without pathological fractures. MATERIALS AND METHODS: This retrospective exploratory study analyzed FICS procedures on iliac osteolytic bone lesions with and without pathological fracture performed from July 2019 to January 2022 in one tertiary level university hospital. The procedure were performed under general anesthesia, and were CT and fluoroscopically guided. Numerical Pain Rate Score (NPRS), mean EuroQol visual analogue scale (EQ VAS), morphine consumption, walking ability, walking perimeter and presence of walking aids and the appearance of complications were evaluated. RESULTS: Nineteen procedures among 18 patients were carried out with a mean follow up time of 243.3 ± 243.2 days. The mean of the maximum NPRS decreased from 8.4 ± 1.3 to 2.2 ± 3.1 at 1 month (p < 0.01) and remained between 1.3 and 4.1 during a follow-up consultation period of 3-24 months. The mean EQ VAS rose from 42.0 ± 12.5 to 57.3 ± 13.9 at 1 month (p < 0.01) follow-up and remained between 55.8 and 62.5 thereafter. No patient scores returned to pre-procedure levels during follow-up. Mean morphine use decreased from 111.1 ± 118.1 to 57.8 ± 70.3 mg/d at 1 month (p > 0.05) follow-up. No late adverse events were reported. CONCLUSION: Percutaneous FICS is a safe procedure with fast and long-standing effect on pain, mobility and quality of life. It can be used as a complement to the known analgesic therapeutic arsenal for bone metastases.

(1) Background: 18F-FDG PET/CT diagnostic accuracy for liver metastasis (LM) could be influenced by technical parameters, lesion size, and the patient's covariates. This retrospective study aimed to evaluate these covariates' impact on PET/CT sensitivity. (2) Methods: Consecutive patients with suspected LMs who underwent 18F-FDG PET/CT scans were included. PET/CT scans were interpreted visually. The reference standard integrated histopathological and imaging follow-up. Logistic regression modeling and average marginal predictions were used to calculate per-lesion diagnostic performance measures with cluster robust 95% confidence intervals and to assess the covariates' impact on PET/CT sensitivity. (3) Results: We included 192 patients with 330 lesions. 18F-FDG PET/CT exhibited a per-lesion sensitivity, specificity, positive predictive value, and negative predictive value of 86%, 79%, 91%, and 69%, respectively. In multivariate analysis, TOF PET/CT exhibited a higher sensitivity than non-TOF PET/CT (91% vs. 78%, p = 0.02). Sensitivity was reduced for lesions < 10 mm compared to larger lesions (56% vs. 93%, p < 0.001). A 5 kg/m2 increase in BMI led to an average 5% sensitivity reduction (p < 0.001). Age, sex, blood glucose level below 11 mmol/L, and liver density did not significantly impact sensitivity (p > 0.05). (4) Conclusions: 18F-FDG PET/CT sensitivity might be reduced with non-TOF PET, lesions < 10 mm, and higher BMI.
RESUMO
BACKGROUND: Meniscal repair for a traumatic meniscal tear is increasingly used to preserve the meniscus. Interpreting postoperative magnetic resonance imaging (MRI) scans remains challenging, especially in symptomatic patients. There is a lack of reliable MRI criteria to affirm the healed character of a traumatic meniscal injury repair. PURPOSE: To identify relevant MRI criteria for meniscal healing after meniscal repair. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: We prospectively included all patients with a traumatic meniscal injury who underwent either an isolated meniscal repair or a repair during a concomitant anterior cruciate ligament reconstruction. A standardized preoperative and postoperative clinical evaluation was performed, along with collection of functional scores-Knee injury and Osteoarthritis Outcome Score, International Knee Documentation Committee, Lysholm Score, and 36-Item Short Form Health Survey. An MRI scan was performed 1 year postoperatively and compared with the preoperative MRI scan. The following MRI aspects were analyzed: variation of morphology and fat-saturated (FS) T2 intensity signal and pre- and postoperative tear diastasis measurement. RESULTS: Fifty patients (age, mean ± SD, 28.7 ± 8.5 years [range, 16-45 years]) who were 1 year postoperative were included. All patients were considered clinically healed had the same MRI characteristics. A signal change (FS T2) was observed from a high signal intensity fluid to a nonfluid moderate signal intensity. The morphology of the lesion was more complex: from the initial lesion, line ramifications appeared, creating the appearance of tree branches. The tear diastasis decreased (from 2.3 ± 0.5 mm [range, 1.3-3.5] to 1.1 ± 0.28 mm [range, 0.5-1.5]). CONCLUSION: MRI criteria confirming meniscal healing after traumatic meniscal repair at 1 year were identified: a change in the intrameniscal signal becoming nonfluid and moderate in intensity; a reduction in tear diastasis to <1.5 mm; and a change in the signal morphology of the repaired meniscus.

Uterine rupture (UR) is an unexpected, rare, and serious obstetrical condition, occurring in less than 0.1% of pregnancies. Complete UR is defined as a direct communication between the uterine cavity and the peritoneum due to a complete rupture of the myometrium. Here, we present 2 cases of non-surgical management of UR following vaginal delivery, which were both treated by uterine transarterial embolization (UAE). A 26-year-old woman (G0P0) was referred to the emergency ward at 35 weeks of amenorrhea to treat the rupture of membranes, in the context of twin pregnancy. A vaginal delivery was performed and blood loss exceeded 2 liters. Gelatin sponge was injected in an attempt to occlude the right uterine artery. The injection was unsuccessful. After the medical team's discussion, it was decided to definitively occlude the right uterine artery. A 37-year-old woman (G3P3) was referred for a vaginal delivery for a medical termination at 38 weeks of amenorrhea. The ultrasound revealed a left latero-uterine pelvic hematoma, suggestive of UR. Four fibered coils were used to definitively occlude the left uterine artery. Computed tomography scan showed a progressive resorption of hematoma and satisfactory enhancement of the uterine wall in the 2 cases. Transarterial embolization may allow for bleeding to stop without resorting to exploratory laparotomy, with ad-integrum restitution of the uterine wall, and thus prevent a potential hysterectomy. The findings in these 2 cases suggest that UAE should be considered if pregnant women develop UR after delivery.
RESUMO
CONTEXT: Hamstring muscle injury location using magnetic resonance imaging (MRI) is not so well described in the literature. OBJECTIVE: To describe the location of hamstring injuries using MRI. DATA SOURCES: PubMed, Web of Science, Scopus, SPORTDiscus, Cochrane Library. STUDY SELECTION: The full text of studies, in English, had to be available. Case reports and reviews were excluded. Included studies must report the location of hamstring injuries using MRI within 8 days of the acute injury. STUDY DESIGN: Systematic review. LEVEL OF EVIDENCE: Level 4. DATA EXTRACTION: A first screening was conducted based on title and abstract of the articles. In the second screening, the full text of the remaining articles was evaluated for the fulfillment of the inclusion criteria. RESULTS: From the 2788 references initially found in 5 databases, we included 34 studies, reporting a total of 2761 acute hamstring injuries. The most frequent muscle head involved was the long head of the biceps femoris (BFLH) (70%), followed by the semitendinosus (ST) (15%), generally associated with BFLH. The most frequent tissue affected was the myotendinous junction (MTJ) accounting for half the cases (52%). Among all lesions, the distribution between proximal, central, and distal lesions looked homogenous, with 34.0%, 33.4% and 32.6%, respectively. The stretching mechanism, while only reported in 2 articles, represented 3% of all reported mechanisms, appears responsible for a specific lesion involving the proximal tendon of the semimembranosus (SM), and leading to a longer time out from sport. CONCLUSION: BFLH was the most often affected hamstring injuries and MTJ was the most affected tissue. In addition, the distal, central, and proximal locations were homogeneously distributed. We also noted that MRI descriptions of hamstring injuries are often poor and did not take full advantage of the MRI strengths. SYSTEMATIC REVIEW REGISTRATION: Before study initiation, the study was registered in the PROSPERO International prospective register of systematic reviews (registration number CRD42018107580).

The severity of SARS-CoV-2 virus infection is mainly related to its respiratory complications. However, it can also lead to a large variety of thromboembolic events. Symptoms may include headache, fever, and neurological disorders. Since 2020, the clinical presentation of COVID-19 infection has become increasingly varied, leading in some cases to complex symptom associations, including numerous neurological symptoms. SARS-CoV-2 may lead to neurotropism which could reach the central nervous system and all cranial nerves. Cavernous sinus thrombosis is a rare condition and may occur as a complication of ear, nose, and throat (ENT) or facial infections. A 73-year-old man without personal or family history of thrombosis was referred to the emergency room for a sudden appearance of diplopia and ptosis, 3 days after testing positive for COVID-19 infection. An initial head CT-scan found no signs of stroke. He underwent a cerebral MRI 7 days later, which revealed a thrombosis of his right cavernous sinus. A brain CT scan 7 days later showed regression of the thrombosis with complete recanalization of the cavernous sinus. This was accompanied by a complete regression of diplopia and fever. He was discharged from the hospital 10 days after hospital admission. In this case report, we describe a rare event of cavernous thrombophlebitis following a COVID-19 infection.
RESUMO
BACKGROUND: To evaluate the effect of tract embolization (TE) with gelatin sponge slurries during a percutaneous lung biopsy on chest tube placement and to evaluate the predictive factors of chest tube placement. METHODS: Percutaneous CT-guided lung biopsies performed with (TE) or without (non-TE) tract embolization or between June 2012 and December 2021 at three referral tertiary centers were retrospectively analyzed. The exclusion criteria were mediastinal biopsies, pleural tumors, and tumors adjacent to the pleura without pleural crossing. Variables related to patients, tumors, and procedures were collected. Univariable and multivariable analyses were performed to determine risk factors for chest tube placement. Furthermore, the propensity score matching analysis was adopted to yield a matched cohort. RESULTS: A total of 1157 procedures in 1157 patients were analyzed, among which 560 (48.4%) were with TE (mean age 66.5 ± 9.2, 584 men). The rates of pneumothorax (44.9% vs. 26.1%, respectively; p < 0.001) and chest tube placement (4.8% vs. 2.3%, respectively; p < 0.001) were significantly higher in the non-TE group than in the TE group. No non-targeted embolization or systemic air embolism occurred. In the whole population, two protective factors for chest tube placement were found in univariate analysis: TE (OR 0.465 [0.239-0.904], p < 0.05) and prone position (OR 0.212 [0.094-0.482], p < 0.001). These data were confirmed in multivariate analysis (p < 0.001 and p < 0.0001 respectively). In the propensity matched cohort, TE reduces significatively the risk of chest tube insertion (OR = 0.44 [0.21-0.87], p < 0.05). CONCLUSIONS: The TE technique using standardized gelatin sponge slurry reduces the need for chest tube placement after percutaneous CT-guided lung biopsy. CRITICAL RELEVANCE STATEMENT: The tract embolization technique using standardized gelatin sponge slurry reduces the need for chest tube placement after percutaneous CT-guided lung biopsy. KEY POINTS: 1. Use of tract embolization with gelatine sponge slurry during percutaneous lung biopsy is safe. 2. Use of tract embolization significantly reduces the risk of chest tube insertion. 3. This is the first multicenter study to show the protective effect of tract embolization on chest tube insertion.
RESUMO
INTRODUCTION: The aim of this retrospective monocentric study was to assess the safety and efficacy of spontaneous soft-tissue hematoma transarterial embolization (TAE) and to evaluate predictive factors for early mortality (≤30 days) after TAE for spontaneous soft-tissue hematoma (SSTH). MATERIALS AND METHODS: Between January 2010 and March 2022, all patients referred to our hospital for spontaneous soft-tissue hematoma and treated by emergency TAE were reviewed. Inclusion criteria were patients: ≥18-year-old, with active bleeding shown on preoperative multidetector row computed tomography, with spontaneous soft-tissue hematoma, and treated by TAE. Exclusion criteria were patients with soft-tissue hematomas of traumatic, iatrogenic, or tumoral origin. Clinical, biological, and imaging records were reviewed. Imaging data included delimitation of hematoma volume and presence of fluid level. Univariate and multivariate analyses were performed to check for associations with early mortality. RESULTS: Fifty-six patients were included. Median age was 75.5 [9-83] ([Q1-Q3] years and 23 (41.1%) were males. Fifty-one patients (91.1%) received antiplatelet agent and/or anticoagulant therapy. All 56 patients had active bleeding shown on a preoperative CT scan. Thirty-seven (66.0%) hematomas involved the retroperitoneum. Median hemoglobin level was 7.6 [4.4-8.2] g/dL. Gelatine sponge was used in 32/56 (57.1%) procedures. Clinical success was obtained in 48/56 (85.7%) patients and early mortality occurred in 15/56 (26.8%) patients. In univariate and multivariate analysis, retroperitoneal location and volume of hematoma were associated with early mortality. CONCLUSION: Retroperitoneal location and volume of hematoma seem to be risk factors for early death in the context of TAE for spontaneous soft-tissue hematoma. Larger multicenter studies are necessary to identify others predictive factors for early mortality and to anticipate which patients may benefit from an interventional strategy with TAE.
RESUMO
OBJECTIVE: Retrievable inferior vena cava filters (IVCF) have been developed because permanent filters have been associated with an increased risk of recurrent deep venous thrombosis. There is no data on the interactions of IVCF with the inferior vena cava (intrafilter thrombi, insertion through the venous wall) even though this may alter the course after retrieval of the IVCF. METHODS: A review of 85 consecutive patients undergoing retrieval of IVCF placed at a single center was performed from January 1, 2010 and December 31, 2014. Inferior vena cava filter were examined for presence of intrafilter thrombus at time of retrieval. Filter position and presence of intraluminal thrombus were examined. Patient outcomes, including recurrence of deep vein thrombosis (DVT) and death, were captured at 3 month followup. RESULTS: Eighty five patients were identified, with intrafilter thrombi found in 69 (81%) patients and venous wall fragments found in 75 (88%) patients. However, their presence was not associated with an increased risk of recurrent venous thromboembolism (VTE) or death during follow up. CONCLUSIONS: Intrafilter thrombi and venous wall fragments are frequently found in removed IVCF but are not associated with a worse prognosis. They may not modify the therapeutic management of patients.

BACKGROUND: Patients with spontaneous or traumatic active mesenteric bleeding cannot be treated endoscopically. Transarterial embolization can serve as a potential alternative to emergency surgery. Literature on transarterial embolization for mesenteric bleeding remains very scarce. The objective of this study was to evaluate the safety and efficacy of transarterial embolization for mesenteric bleeding. We reviewed all consecutive patients admitted for mesenteric bleeding to the interventional radiology department, in a tertiary center, between January 2010 and March 2021. Mesenteric bleeding was defined as mesenteric hematoma and contrast extravasation and/or pseudoaneurysm visible on pre-operative CT scan. We evaluated technical success, clinical success, and complications. RESULTS: Among the 17 patients admitted to the interventional department for mesenteric bleeding, 15 presented with active mesenteric bleeding requiring transarterial embolization with five patients with hemodynamic instability. Mean age was 67 ± 14 years, including 12 (70.6%) males. Technical success was achieved in 14/15 (93.3%) patients. One patient with technical failure was treated by percutaneous embolization with NBCA-Lipiodol mixture. Three patients (20%) had early rebleeding: two were treated by successful repeat embolization and one by surgery. One patient (6.7%) had early death within 30 days and two patients (13.3%) had late death after 30 days. Mean length of hospitalization was 12.8 ± 7 days. There were no transarterial embolization-related ischemic complications. CONCLUSION: Transarterial embolization is a safe and effective technique for treating mesenteric bleeding even in patients with hemodynamic instability. Transarterial embolization doesn't close the door to surgery and could be proposed as first intention in case of mesenteric bleeding.
