    Abstract Antiphospholipid syndrome is an autoimmune condition characterized by arteriovenous thromboembolic events. Thrombocytopenia is a common finding among these patients and is typically of mild severity not requiring any treatment. However, severe cases of thrombocytopenia should be treated. Steroids, intravenous immune globulin (IVIG), and immunomodulatory agents are the first-line treatment options, and surgical splenectomy is usually reserved for more severe and refractory cases of thrombocytopenia. Herein, we report the case of a 30-year-old man with primary antiphospholipid syndrome and severe thrombocytopenia. The patient's thrombocytopenia had been refractory to almost all the medical managements, and surgical splenectomy could not be an option due to the patient's high-risk condition for surgery. The patient was successfully managed by partial splenic embolization (PSE) which was a unique application of this technique.

    Abstract Background: Hepatic venous malformation (HVM), traditionally called liver haemangioma, is considered the most common benign hepatic lesion. Treatment might be indicated in large and symptomatic HVMs. We aim to describe stepwise technical aspects of trans-hepatic percutaneous sclerotherapy of hepatic venous malformation (HVM).
    Main text: Patients with symptomatic HVM larger than 5 cm are selected after discussion in hepatobiliary multidisciplinary team. After prophylactic antibiotic and corticosteroid administration, local anaesthesia and conscious sedation are applied. A 22-gauge spinal or Chiba needle is used to obtain percutaneous access to the HVM through normal liver parenchyma under ultrasound guidance. To ensure proper needle placement and to prevent accidental delivery of sclerosant into unintended areas, about 5-10 mL iodine contrast is injected under fluoroscopy. Then, 45-60 IU bleomycin is mixed with 10 mL distilled water and 10 mL lipiodol and is slowly injected under fluoroscopy over a period of 20-30 s. After the needle is removed, manual pressure is applied over the puncture site for a period of 5 min followed by placement of a sandbag. Patients are monitored for 6-8 h post-procedure.
    Conclusion: In this technical review, we described our institutional technique of percutaneous sclerotherapy, which could be regarded as an alternative to TAE in the management of HVM.

    Abstract Purpose: To retrospectively assess the correlation between pulmonary arterial obstruction index (PAOI) and right lateral ventricular wall thickness with in-hospital mortality in patients with acute pulmonary embolism.
    Methods: CT angiography (CTA) of 55 consecutive patients (30 males; 25 females; mean age ± SD, 59 ± 11 years) with proven acute pulmonary embolism was investigated. PAOI was determined according to the Qanadli score on CTA. Right ventricular lateral wall thickness was also measured, and patients' in-hospital mortality was recorded. The correlation between PAOI and mortality, right ventricular lateral wall thickness and mortality, and PAOI and right ventricular lateral wall thickness was evaluated.
    Results: PAOI was 23.6 and 10.4 in patients with and without in-hospital mortality, respectively (P < 0.001). Right ventricular lateral wall thickness was 8.7 mm and 7.5 mm in patients with and without in-hospital mortality, respectively (P < 0.001). PAOI more than 21.5 and right ventricular lateral wall thickness more than 8.75 were predictive of in-hospital mortality with a high accuracy. Also, PAOI and right ventricular lateral wall thickness had a significant correlation with each other (P < 0.001; r = 0.695).
    Conclusion: PAOI and right ventricular lateral wall thickness on CTA were highly predictive of in-hospital mortality in patients with pulmonary embolism. Right ventricular lateral wall thickness and PAOI had a significant correlation with each other as well.

    Abstract This prospective study evaluated the safety and effectiveness of percutaneous sclerotherapy in the treatment of secondary Budd-Chiari syndrome due to hepatic venous malformations (HVMs). Four patients (mean age, 40 years; 3 women) with 5 HVMs underwent 7 sessions of percutaneous sclerotherapy with a mixture of bleomycin and lipiodol. All patients had chronic Budd-Chiari syndrome, determined based on imaging findings, with the main symptom being abdominal discomfort and distention. On physical examination, 2 patients had ascites and the other 2 had an epigastric mass. The indication for treatment was intractable abdominal symptoms due to hepatic and/or inferior vena cava (IVC) outflow compression. All procedures were technically successful, with no major complications. Three patients underwent a second session because of incomplete IVC decompression. The patients' symptoms completely resolved at 6 and 12 months of follow-up. There was a significant reduction in lesion volume (P = .007) and an increase in IVC luminal area (P = .018) at 12 months of follow-up.

    Abstract Background Percutaneous sclerotherapy with bleomycin has been proven to have a potential benefit in the management of low-flow venous malformations. Liver hemangiomas are considered low-flow venous malformations. Thus, percutaneous sclerotherapy could potentially have a promising result in their management. Purpose To investigate the feasibility, efficacy, and safety of percutaneous sclerotherapy with bleomycin in the management of symptomatic giant liver hemangioma (GLH). Materials and Methods This single-institute prospective study was conducted between September 2018 and July 2020. Percutaneous sclerotherapy was performed using a mixture of bleomycin and ethiodized oil under guidance of US and fluoroscopy in participants with GLH who were experiencing related abdominal pain or fullness. Technical success was recorded. Change in symptom severity, according to visual analog scale (VAS), was considered the primary outcome of the study. Volume change, based on the lesion volume at CT, and complications, based on the classification of the Society of Interventional Radiology, were regarded as secondary outcomes. The primary and secondary outcomes were recorded 6 and 12 months after the procedure. Comparison was performed by using the Wilcoxon signed-rank test or paired

    Abstract We evaluated the added value of lung window in non-contrast computed tomography (CT) of suspected body packers or stuffers. Forty suspected drug mules who were referred to our tertiary toxicology center were included. The final diagnosis of drug mule was based on the detection of packs in stool examination or surgery. Non-contrast CT scans were retrospectively interpreted by two blinded radiologists in consensus before and after reviewing the lung window images. The diagnostic performance of abdominal window scans alone and scans in both abdominal and lung windows were subsequently compared. Seven body packers and 21 body stuffers were identified. The sensitivity, negative predictive value (NPV), and diagnostic accuracy of scans in detection of drug mules (either drug packers or stuffers) raised from 60.7, 52.1, and 72.5 to 64.2, 54.5, and 75.0 %, respectively, with a more number of packs being detected (114 vs. 105 packs). In the body packers group, the diagnostic performance of both abdominal windows scans and combined abdominal and lung windows scans were 100 %. In the body stuffers group, the sensitivity, NPV, and diagnostic accuracy of scans increased from 47.6, 52.1, and 55.0 to 52.3, 54.5, and 57.5 %, respectively, after the addition of lung windows. Reviewing the lung window on non-contrast abdominal CT can be helpful in detection of drug mules.

    Abstract Since the outbreak of Coronavirus Disease 2019 (COVID-19) causing novel coronavirus (2019-nCoV)-infected pneumonia (NCIP), over 45 million affected cases have been reported worldwide. Many patients with COVID-19 have involvement of their respiratory system. According to studies in the radiology literature, chest computed tomography (CT) is recommended in suspected cases for initial detection, evaluating the disease progression and monitoring the response to therapy. The aim of this article is to review the most frequently reported imaging features in COVID-19 patients in order to provide a reliable insight into expected CT imaging manifestations in patients with positive reverse-transcription polymerase chain reaction (RT-PCR) test results, and also for the initial detection of patients with suspicious clinical presentation whose RT-PCR test results are false negative. A total of 60 out of 173 initial COVID-19 studies, comprising 7571 individuals, were identified by searching PubMed database for articles published between the months of January and June 2020. The data of these studies were related to patients from China, Japan, Italy, USA, Iran and Singapore. Among 40 reported features, presence of ground glass opacities (GGO), consolidation, bilateral lung involvement and peripheral distribution are the most frequently observed ones, reported in 100%, 91.7%, 85%, and 83.3% of articles, respectively. In a similar way, we extracted CT imaging studies of similar pulmonary syndromes outbreaks caused by other strains of coronavirus family: Middle East Respiratory Syndrome (MERS) and Severe Acute Respiratory Syndrome (SARS). For MERS and SARS, 2 out of 21 and 5 out of 153 initially retrieved studies had CT findings, respectively. Herein, we have indicated the most common coronavirus family related and COVID-19 specific features. Presence of GGO, consolidation, bilateral lung involvement and peripheral distribution were the features reported in at least 83% of COVID-19 articles, while air bronchogram, multi-lobe involvement and linear opacity were the three potential COVID-19 specific CT imaging findings. This is necessary to recognize the most promising imaging features for diagnosis and follow-up of patients with COVID-19. Furthermore, we identified co-existed CT imaging features.

    Abstract Inferior mesenteric arteriovenous fistula (AVF) is an extremely rare vascular abnormality which may be idiopathic or secondary to previous trauma or surgery, and it may result in portal hypertension or ischemic colitis if left untreated. Imaging can help accurately diagnose visceral AVFs and create a vascular map to display the feeding artery and draining vein before the surgery; however, multidetector computed tomography (MDCT) angiography of inferior mesenteric AVF is not well documented in the literature. In this article, the authors report a case of inferior mesenteric AVF in a 48-year-old woman evaluated for left-sided abdominal pain and diagnosed preoperatively by MDCT angiography. Surgical excision of the AVF was successfully performed, and the postoperative course was uneventful.
