RESUMO
BACKGROUND: The growth of the liver and spleen is a dynamic process in children, and is related to the somatic parameters of the child, and may be affected by many diseases in children. It is of paramount importance to have standard reference values for the size of these organs for diagnostic and prognostic purposes. The aim of our study was to provide practical and reliable normal reference values for the size of the liver and spleen in children and to correlate the values with age, height, and weight. METHODS: Three hundred fifteen children (142 boys and 173 girls) were prospectively examined by ultrasound due to problems unrelated to the liver or spleen. All of the subjects had normal sonographic appearance of their organs. The ages of the subjects ranged from newborns to 14 years. The liver and spleen size was correlated with age, height, and weight. The spleen size was compared with previous internationally published data. RESULTS: There was no statistical significant difference in the size of the liver and spleen between boys and girls (P>0.05). There was steady increase in the size of the liver and spleen, with good correlation with age and all the somatic parameters. The spleen size was in close proximity to those previously reported in the literature. CONCLUSIONS: Standard spleen and liver size reference values were obtained by ultrasound for Jordanian children and were in concordance with international values.

PURPOSE: This study aimed to investigate the anatomical variations in direct branches of the aortic arch in Jordanians using the contrast Computed Tomography (CT) imaging techniques and to determine their prevalence according to sex. METHODS: This analytical, retrospective study included 500 patients (209 females, 291 males), who were referred to the Radio-Diagnostic Department at King Abdullah University Hospital for CT angiography of the aortic arch from 2010 to 2014. Patients were selected using a random sampling method. RESULTS: Six patterns of arrangement of arteries according to their origin from the aortic arch were identified in Jordanians. The most common pattern was the normal classical one and accounted for 61.2 % of cases. All other patterns were considered variations and accounted for 38.8 % of cases. Variation patterns were classified into six different types. There was no significant correlation (p > 0.05) between sex and the occurrence of different types of variations. CONCLUSION: This study provides new information regarding the prevalence of aortic arch branching variations in Jordanians. A wide range of anatomical variations in the branching pattern of the aortic arch was observed. This should be taken into consideration during angiography, aortic instrumentation, and supra-aortic thoracic, head, and neck surgery.

This document by an expert panel of the International Society for Neurovascular Disease is aimed at presenting current technique and interpretation of catheter venography of the internal jugular veins, azygous vein and other veins draining the central nervous system. Although interventionalists agree on general rules, significant differences exist in terms of details of venographic technique and interpretations of angiographic pictures. It is also suggested that debatable findings should be investigated using multimodal diagnostics. Finally, the authors recommend that any publication on chronic cerebrospinal venous insufficiency should include detailed description of venographic technique used, to facilitate a comparison of published results in this area.

Objective: COVID-19 has an increased burden on the delivery of services because the measures taken by the governments forced hospitals to cancel most of their elective procedures and led to the shutting down of outpatient clinics. This study aimed to evaluate the impact COVID-19 pandemic on the volume of radiology exams based on patient service locations and imaging modality in the North of Jordan. Methods: The imaging case volumes that were performed at the King Abdullah University Hospital (KAUH), Jordan, from 1 January 2020 to 8 May 2020, were retrospectively collected and compared to those from 1 January 2019 to 28 May 2019, to determine the impact of the pandemic of COVID-19 on the volume of radiological examinations. The 2020 study period was chosen to cover the peak of COVID-19 cases and to record the effects on imaging case volumes. Results: A total of 46,194 imaging case volumes were performed at our tertiary center in 2020 compared to 65,441 imaging cases in 2019. Overall, the imaging case volume in 2020 decreased by 29.4% relative to the same period in 2019. The imaging case volumes decreased for all imaging modalities relative to 2019. The number of nuclear images showed the highest decline (41.0%) in 2020, followed by the number of ultrasounds (33.2%). Interventional radiology was the least affected imaging modality by this decline, with about a 22.9% decline. Conclusion: The number of imaging case volumes decreased significantly during the COVID-19 pandemic and its associated lockdown. The outpatient service location was the most affected by this decline. Effective strategies must be adopted to avoid the aforementioned effect on the healthcare system in future pandemics.
RESUMO
Purpose: Chronic limb-threatening ischemia in patients with diabetes is associated with a high risk of adverse outcomes. The associated co-morbidities, the heterogeneity of foot presentation and the distribution of atherosclerotic lesions led to the emergence of multiple revascularization strategies and scoring systems to improve management outcomes. This study aimed to introduce a new index, the revascularization index (RI), and to assess its predictive value for the outcomes of primary endovascular intervention in patients with type 2 diabetes presenting with chronic limb-threatening ischemia. Patients and Methods: A retrospective electronic medical records review was conducted for patients with type 2 diabetes presenting with chronic limb-threatening ischemia managed at King Abdullah University Hospital by primary endovascular interventions between January 2014 and August 2019. The RI was analyzed for its predictive value for the treatment outcomes. Results: A total of 187 patients were included in this study, with a major lower limb amputation rate of 19.3%. The performance of the RI was excellent in predicting secondary revascularization (AUC = 0.80, 95% CI: 0.73-0.86, p-value < 0.001), good to predict major amputation (AUC = 0.76, 95% CI: 0.67-0.85, p-value = 0.047), and poor in predicting death (AUC = 0.46, 95% CI: 0.40-0.55, p-value = 0.398). RI of <1.21 was significantly associated with a higher risk of major lower limb amputation (HR = 5.8, 95% CI: 1.25-26.97, p-value < 0.025), and RI of < 1.3 was associated with a higher risk for secondary revascularization. Conclusion: The RI can be used to predict major adverse lower limb events (MALE). It might be used as a guide for the extent of endovascular interventions for diabetic chronic limb-threatening ischemia with multi-level outflow atherosclerotic disease.

BACKGROUND Most thyroid nodules are fortunately benign; however, up to 15% of thyroid nodules turn out to be malignant. Follicular thyroid cancer is the second most common type of thyroid malignancy, originating from the follicular cells lined by cuboidal epithelium, with a peak incidence between the ages of 40 and 60 years. The feature that differentiates follicular carcinoma from adenoma is the presence of capsular invasion. While distant metastases occur in 10% to 15% of patients with follicular thyroid cancer, only 2% to 13% of patients with thyroid cancer develop bone metastases. Metastasis to the knee in thyroid cancer is extremely rare. This report describes a rare case of limping and knee pain as presenting symptoms of metastasis of follicular thyroid cancer to the knee joint observed during clinical practice and addresses its implications. CASE REPORT A 60-year-old woman presented with right knee swelling, disabling pain, and difficulty with walking in the last 3 months. Magnetic resonance imaging showed a large mass, and a computed tomography scan-guided biopsy confirmed it to be a distant metastasis of follicular thyroid cancer. The patient underwent total knee replacement and thyroidectomy and was postoperatively treated with radioactive iodine therapy. She was in good condition at her 1-year follow-up, with no recurring pathology. CONCLUSIONS This case reports on the metastasis of follicular thyroid cancer to the knee, which is exceedingly rare. However, it should be considered in the differential diagnoses of lytic bone lesions, as early diagnosis and management yield a more favorable prognosis for patients.

STUDY DESIGN: Retrospective study. OBJECTIVE: To describe the MRI findings of RNRs in patients with low back pain, and observe the imaging findings and the clinical outcome post decompression surgery. METHODS: The lumbar spine MRI of 202 patients (122 females) with proven RNRs were retrospectively reviewed. The morphology and the location of the RNRs in relation to the level of stenosis were described. The level(s), grade and cause of lumbar canal stenosis were recorded. The persistence of symptoms and the imaging findings on follow up post decompression surgery were recorded. The imaging findings were correlated among each other and with patients' demographics. RESULTS: Two distinctive morphological appearance of the RNRs were noted: loop (56.4%), and serpentine-shaped. In the majority of the cases the RNRs were located above the level of stenosis (79.7%). Eighteen patients underwent decompression surgery, only 4 patients remained symptomatic post decompression surgery. The RNRs changed in shape and location after decompression surgery. Age was a strong predictor value in the location of the RNRs. There was no correlation between the shape and location of the RNRs, or with the gender of the patients. CONCLUSION: RNRs is not an uncommon finding on lumbar spine MRI with lumbar canal stenosis. Its importance remains a controversy. A common language between the radiologists and the clinicians is mandatory to aid in the management planning.
RESUMO
Introduction: Hospitalized patients with coronavirus disease (COVID-19) often undergo chest x-ray (CXR). Utilizing CXR findings could reduce the cost of COVID-19 treatment and the resultant pressure on the Jordanian healthcare system. Methods: We evaluated the association between the CXR severity score, based on the Radiographic Assessment of Lung Edema (RALE) scoring system, and outcomes of patients with COVID-19. The main objective of this work is to assess the role of the RALE scoring system in predicting in-hospital mortality and clinical outcomes of patients with COVID-19. Adults with a positive severe acute respiratory syndrome COVID-19 two reverse-transcription polymerase chain reaction test results and a baseline CXR image, obtained in November 2020, were included. The RALE severity scores were calculated by expert radiologists and categorized as normal, mild, moderate, and severe. Chi-square tests and multivariable logistic regression were used to assess the association between the severity category and admission location and clinical characteristics. Results: Based on the multivariable regression analysis, it has been found that male sex, hypertension, and the RALE severity score were significantly associated with in-hospital mortality. The baseline RALE severity score was associated with the need for critical care (P<0.001), in-hospital mortality (P<0.001), and the admission location (P=0.002). Discussion: The utilization of RALE severity scores helps to predict clinical outcomes and promote prudent use of resources during the COVID-19 pandemic.
RESUMO
PURPOSE: To describe the radiological characteristics for childhood intussusceptions including unusual radiological features and rare pathological lead points (PLP). MATERIAL AND METHODS: The medical records of all childhood intussusceptions between 1/1/2010 -1/10/2020 were retrospectively reviewed. 95 cases were identified in 82 patients. The demographic data, presenting symptoms, diagnostic and treatment methods, radiological features, and PLPs among the different types of intussusception were analyzed. RESULTS: Ileocolic intussusception (ICI) represented 53.7% (51/95). The average age for ICI was 1.87 years. Males constituted 72.1% (31/43). 29.4% (15/51) were treated primarily surgically due to peritonitis. Small bowel intussusception (SBI) represented 40% (38/95) in which females constituted 51.5% (17/33). Ileo-ileal represented 63.2% (24/38). 81.8% (27/33) were transient. On ultrasound; There was a statistically significant difference in the size of the outer diameter of ICI compared to SBI (P-value 0.00012). Ileo-ileocolic and colo-colic intussusceptions constituted 3.2% (3/95); each and were more common in females. Vomiting was the most common symptom for intussusception and ultrasound was diagnostic in the majority of cases. PLPs were seen in 36.6% (30/82) of the patients of which the average age was 7 years. PLPs/risk factors were benign in 80% (24/30). A case of colo-colic intussusception was seen in a 16-year-old female due to clear cell sarcoma which was not reported before. 12.2% patients (10/82) had recurrent intussusception. CONCLUSION: Our study showed that ICI is the most commonly encountered type. SBIs are mostly transient. It is important to radiologically determine the type of intussusception and to identify PLPs or unusual radiological features to avoid unnecessary intervention and significant patient morbidity.
RESUMO
INTRODUCTION: The novel COVID-19 pandemic has imposed unprecedented restrictions on healthcare services worldwide. In developing nations such as Jordan, appreciable impacts on healthcare delivery ensued owing to limited resources. As a result, managing chronic limb-threatening ischemia (CLTI) has been modified to accommodate altercations in the system. This study assessed the impact of the COVID-19 pandemic on managing patients with critical limb-threatening ischemia (CLTI) during the lockdown. METHODS: Objectives were accomplished by retrieving records of clinical data and perioperative results for patients diagnosed with CLTI at King Abdullah University Hospital between March 17 and June 1, 2020. Patients' demographics, Rutherford classification, type of intervention, and intervention variables during the outbreak were retrospectively analyzed (pandemic Group A) and compared with patients from the same period last year (control Group B). RESULTS: A total of 96 patients with CLTI were included in the study; Groups A and B consisted of 28 and 68 patients, respectively. The mean ages for Groups A and B were 62.8 and 60.2 years, respectively. Conservative management was applied to 53.6% (P < 0.01) of Group A patients, whereas endovascular revascularization was the primary approach in Group B (39.7%, P < 0.01). After the intervention, the majority of patients in Group A were classified as category six on the Rutherford classification system (46.4%, P < 0.01), whereas the majority in group B were classified as category five (55.9%, P < 0.01). CONCLUSIONS: The more unsatisfactory outcome of CLTI during the pandemic entails substantial measures to ensure conscientious virtual encounters and ambulatory community-based services during current and future pandemics. The endovascular-first policy should be endorsed in future pandemics as it is better at reducing aerosol transmission than standard surgical intervention. Moreover, endovascular procedures are minimally invasive and associated with favorable outcomes when medical optimization and hospital beds are limited.
RESUMO
BACKGROUND: Candida species are infrequently grown in bile cultures. An association between biliary candidiasis and regional malignancy may exist. The role of fungus membranes in frequent biliary stent occlusion is also presented in this case series. METHODS: We retrospectively identified patients who underwent percutaneous trans-hepatic cholangiogram (PTC) for obstructive jaundice between January 2014 and January 2019. The results of bile cultures - obtained by PTC - for all patients were analyzed, and patients with fungus growth were determined; their medical records were reviewed. RESULTS: A total of 71 patients with obstructive jaundice underwent PTC between January 2015 and January 2019. Five patients (all male; mean age 55.8 years) had candida species growth in bile cultures. Two patients were diagnosed with cholangiocarcinoma, one with adenocarcinoma of the head of the pancreas, one with gallbladder cancer, and one with locally advanced gastric adenocarcinoma. Formation of fungal balls predisposed to frequent PTC drain clogging. Eradication of Candida was achieved in 4 patients after 10 days to 3 weeks of antifungal therapy. CONCLUSION: We present a case series of biliary candidiasis in patients with obstructive jaundice and regional malignancy. We suggest that patients with obstructive jaundice and regional malignancy should be screened for biliary candidiasis. Persistent cholestasis may be caused by the recurrent formation of fungal membranes (balls).
RESUMO
BACKGROUND Inferior vena cava (IVC) filters are indicated for patients with recurrent venous thrombosis despite proper anticoagulation or whenever anticoagulation is contraindicated. IVC filter deployment is an invasive procedure with various complications. One example is IVC filter limb fracture and migration, which is associated with significant morbidity and/or mortality. Extravascular migration toward pancreas may induce pancreatitis. Patients with chronic pancreatitis are known to have an increased risk of pancreatic malignancy. CASE REPORT We report an extremely rare case of IVC filter fractured limb in 44-year-old woman, which had migrated into the pancreatic tail and manifested as chronic distal pancreatitis. A pancreatic adenocarcinoma was found by biopsy at the pancreas tail. It is likely that a foreign body promoted this metaplasia and neoplastic transformation. CONCLUSIONS Early detection and retrieval of a displaced foreign body in organs, such as the pancreas, seem to be essential to reduce risk of subsequent complications, including chronic inflammation and possibly neoplasia.

AIMS: Increased level of glycated hemoglobin (HbA1c) is associated with an increased prevalence of peripheral arterial disease (PAD). This study aimed to assess the relationship between the anatomical distribution of symptomatic PAD lesions in patients with type 2 diabetes and HbA1c levels at the time of PAD diagnosis. PATIENTS AND METHODS: A retrospective study was conducted at King Abdullah University Hospital during the period August 2011 to December 2015. Consecutive patients with type 2 diabetes presented with symptomatic PAD confirmed by computed tomography-angiography (CTA) were included in this study. CTA images were reviewed. Relevant information including demographic data, PAD symptoms, comorbidities, HbA1c level, lipid profile, C-reactive protein and the mean platelets volume were retrieved from medical records. RESULTS: A total of 332 patients with type 2 diabetes (255 males and 77 females) were included in this study. The mean HbA1c at the time of PAD diagnosis was 8.68% (±2.06%). The prevalence of hemodynamic relevant atherosclerotic lesions of the superficial femoral artery, popliteal artery, leg vessels, femoro-popliteal, and crural segments was significantly higher in patients with HbA1c >7.5% compared with patients with HbA1c ⩽7.5%. CONCLUSION: The anatomical distribution of symptomatic PAD in patients with type 2 diabetes mellitus differed significantly according to HbA1c level at the time of PAD diagnosis.
RESUMO
INTRODUCTION: Acute mesenteric ischemia caused by an embolism resulting from atrial fibrillation in a thyrotoxic young male patient is a rare event. Endovascular intervention is increasingly being considered as the primary modality of treatment in selected patients. PRESENTATION OF CASE: A 41-years male known to have hyperthyroidism presented with atrial fibrillation, acute mesenteric ischemia, splenic infarction, and left renal infarction. He was successfully managed with endovascular intervention of the superior mesenteric artery. DISCUSSION: Acute mesenteric ischemia has a high mortality rate. CT angiography is the investigation of choice for diagnosis of the mesenteric vessels occlusion and assessment of bowel ischemia. The clinical presentation guides into the treatment and the choice between open surgery and endovascular intervention as the primary modality of treatment. Thyrotoxicosis is a risky comorbid condition for any procedure to be done, so proper perioperative management is essential to decrease morbidity and mortality. CONCLUSION: Prompt diagnosis and management of acute mesenteric ischemia is essential to decrease the morbidity and mortality rates. Endovascular management can be considered as a primary modality of treatment in selected cases.
RESUMO
BACKGROUND This report describes the endovascular management of a Celt ACD® vascular closure device (VCD) lodged in the superficial femoral artery (SFA), 1 year after its deployment. There is a paucity of evidence in the existing literature regarding the management of complications related to embolized VCD discovered months or years after its deployment. CASE REPORT A 70-year-old male patient, who was a heavy smoker, presented with right lower-limb intermittent claudication of 2 months' duration. He underwent a successful left retrograde iliac artery and left SFA angioplasty 1 year ago. The right femoral pulse was normal, whereas the right popliteal pulse was absent. The right ankle-brachial index was 0.64. Doppler ultrasound showed evidence of mid-right SFA occlusion. Angiogram showed an embolized Celt ACD VCD in the right SFA causing segmental occlusion. An endovascular attempt to retrieve the embolized VCD via a snare failed, as the VCD got deeply embedded in the vessel wall. After successful balloon angioplasty, a stent was placed into the SFA with excellent angiographic and clinical outcomes. CONCLUSIONS This case demonstrates the risk of dislodgement of the VCD and its distal embolization with a risk of late ischemia. Endovascular retrieval may be unsuccessful for chronically embolized VCD. Therefore, stent angioplasty is an acceptable option.

OBJECTIVE: The objective of this study is to evaluate the value of FDG PET/CT for different involved organs showing Indeterminate/ equivocal / suspicious lesions detected on IV contrasted CT during surveillance follow up for colorectal cancer. MATERIALS AND METHODS: A total of 67 patients with colorectal cancer how are on regular surveillance follow up by IV contrasted CT scans revealing indeterminate lesions were studied. Subsequent FDG PET/CT evaluation was performed as a problem solving modality. PET/CT results were statistically characterized when compared to biopsy results or to follow/up results. Also Statistical parameters were calculated for each organ involved. The evaluation of all CT indeterminate lesions by FDG PET/CT showed overall sensitivity of 93%, Specificity of 81%, Negative predictive value of 94%, Positive predictive value 80% and accuracy of 87%. However in an organ specific approach the highest accuracy was for lymph nodes with results showing a 100% accuracy and the lowest accuracy was for local disease at a value of 80%. Probable explanations for the falsely characterized lesions resulting in the pitfalls seen and in the imperfect accuracy were provided. CONCLUSION: Study shows that FDG PET/CT is an excellent tool in characterizing CT indeterminate lesions during surveillance of colorectal cancer, However different organs showed variable accuracy results with the highest accuracy for our study was for lymph node status (100%) and the lowest accuracy being for local disease at the original site of primary tumor (80%).
RESUMO
PURPOSE: Central venous lesions (CVLs) can adversely affect hemodialysis access maturation and maintenance, which in turn worsen patient morbidity and access circuit patency. In this study, we assessed several clinical variables, patient characteristics, and clinical consequences of symptomatic central vein stenosis and obstruction in patients who underwent renal replacement therapy in the form of hemodialysis. PATIENTS AND METHODS: The medical records of all hemodialysis patients with clinically symptomatic CVLs who underwent digital subtraction angiography treatment at King Abdullah University Hospital between January 2017 and December 2019 were retrieved. Patient characteristics and the clinical and anatomical features of CVLs were analyzed retrospectively. Pearson's chi-square tests of association were used to identify and assess relationships between patient characteristics and CVLs. RESULTS: The study cohort comprised 66 patients with end-stage renal disease who developed symptomatic central vein stenosis. Of the 66 patients, 56.1% were men, and their mean age was approximately 52 years. Most (62.1%) of the patients were determined to have a history of central catheter insertion into the jugular vein. Hypertension was the most common comorbidity (78.8%, p<0.001), followed by type 2 diabetes mellitus (47.0 %, p<0.01). The incidence of stenosis was found to be significantly higher in the brachiocephalic vein than in other central veins (43.9%, p<0.001). A repeated central catheter insertion in a patient was predictive of central venous occlusion (p<0.05). Stenotic lesions were found to be associated with a significantly higher success rate than occlusive lesions (91.2%, p<0.01). CONCLUSION: Multiple central venous catheters (CVCs) are found to be associated with occlusive CVLs and unfavorable recanalization outcomes. Multiple CVC should be avoided by creating a permanent vascular access in a timely fashion for patients with chronic kidney disease and by avoiding the ipsilateral insertion of CVC and AVF.

BACKGROUND May-Thurner syndrome (MTS) is a condition characterized by compression of the left common iliac vein (LCFV) between the right common iliac artery (RCIA) and the lumbar vertebrae. This anatomical entrapment typically affects young women and is mostly asymptomatic. High index of suspicion is required in cases of recurrent left-sided deep vein thrombosis (DVT) and severe leg pain. We describe a case of MTS in a young male patient with a left-sided superior vena cava (LSSVC) that was successfully managed by an endovascular approach. To the best of our knowledge, the coexistence of MTS and LSSVC anomaly has not been reported previously. CASE REPORT A 31-year-old man presented with a history of left-sided iliofemoral deep vein thrombosis and disabling venous claudication of 2 years' duration. Duplex ultrasound and computed tomography venogram (CTV) revealed evidence of MTS with chronic subtotal occlusion of the left common iliac vein (LCIV) with extensive venous collaterals. Venogram via the left femoral vein puncture confirmed the aforementioned findings. Retrograde recanalization of the occluded segment was attempted without success. Therefore, an antegrade approach via the right internal jugular vein was performed to facilitate recanalization. Surprisingly, venography revealed an LSSVC. The occluded CIV was successfully stented and the patient had complete resolution of his symptoms at 22-month follow-up. CONCLUSIONS MTS is a potentially treatable and often-overlooked pathology. In the era of expanded endovascular management of MTS, recognition of this coincidence is essential to prevent unwarranted mishaps during endovascular management when the jugular approach is used.
