Abstract
Background The objective of this study is the evaluation of routine chest radiography following the placement of Implantable venous access port catheter (IVAPC) central lines using combined ultrasound and fluoroscopic guidance by a vascular surgeon in the operating room. Material and method A prospective study of 189 consecutive patients who underwent IVAPC central line insertion in the vascular surgery operating room from 2016 to 2019. Venipuncture was performed with an 18-gauge needle under the guidance of sonography in each case, and the access site was noted. The line position was confirmed by fluoroscopy following the procedure. Multiple tries for puncture and patients under 18 were excluded from our study. Routine radiography of chest was performed for all patients and pneumothorax, hemothorax, and catheter malposition were evaluated in each case. Results There were 2 cases of asymptomatic pneumothorax, no cases of hemothorax, and all catheter tip positions were optimal or acceptable. The annual cost of chest radiography was 33,000,000IRR, 220 h of hospital and staff time, and 1.1 mSv radiation. Conclusion In conclusion, when imaging guidance is used for IVAPC insertion by an experienced surgeon in a high-volume center, performing post-procedure routine chest radiography shows little benefit.

Abstract
PURPOSE To evaluate the variability in ankle syndesmotic morphology on contralateral ankle fluoroscopic images and the reductions obtained utilizing these images. METHODS A retrospective cohort study was performed at a level one trauma center including 46 adult patients undergoing operative fixation of malleolar ankle fractures that also had anteroposterior (AP) and lateral fluoroscopic images of the uninjured contralateral ankle intraoperatively. Contralateral and post-fixation fluoroscopic images were used to measure the tibiofibular clear space (TFCS) as a proportion of the superior clear space (SCS) on mortise images and the posterior tibiofibular distance (PTFD) as a proportion of the lateral superior clear space (LSCS) on lateral images. Differences between contralateral and post-fixation ankle measurements were compared between those patients with syndesmotic injuries and those without (control group). RESULTS The mean TFCS/SCS and PTFD/LSCS ratios measured on contralateral ankle images were 1.2 (95% confidence interval (CI) 1.1 to 1.3; range 0.7 to 1.8) and 1.8 (95% CI 1.5 to 2; range 0.5 to 3.4). The mean difference between the contralateral and post-fixation TFCS/SCS and PTFD/LSCS in patients with and without syndesmotic fixation was 0.07 vs. 0.13 (F-ratio 0.3, p = 0.5) and -0.2 vs 0.5 (F ratio 5.2, p= 0.02). CONCLUSIONS Contralateral syndesmotic measurements varied widely and the utilization of these images allowed for syndesmotic reductions with similar measurements. Intraoperative contralateral ankle images should be considered to assess syndesmotic reduction.

Abstract
PURPOSE Pneumomediastinum is not an uncommon finding on emergency CTs and is seen in a variety of settings, including acute trauma, recent repeated emesis and recent thoracic surgery, and after EGD (Kouritas et al. J Thorac Dis 7(Suppl 1):S44-S49, 2015). The purpose of this study was to examine cases of CT pneumomediastinum for distinguishing features which could support or exclude esophageal injury as a cause, which in turn could help guide evaluation of these patients. METHODS CT chest scans showing pneumomediastinum performed in the emergency department between January 2013 and December 2018 were included. The presence or absence of fluid within the mediastinal compartments was correlated with esophageal perforation and subdivided into the clinical scenarios of trauma, suspected Boerhaave's syndrome, recent surgery or EGD, and other. Accuracy of this finding was compared with fluoroscopic esophagography. RESULTS Twenty-two cases of esophageal perforation were identified out of a total of 324 included cases. The cases were subdivided into four categories: trauma, suspected Boerhaave syndrome, suspected iatrogenic perforation from recent procedure or surgery, and other. Two hundred fourteen cases of pneumomediastinum occurred in the setting of trauma, and 2 had esophageal perforation. Both showed mediastinal fluid. Twenty-two cases had mediastinal fluid without perforation. Seventeen cases of pneumomediastinum occurred in the setting of suspected Boerhaaves, and 3 had esophageal perforation. Every case with esophageal perforation had mediastinal fluid, and every case without perforation had no mediastinal fluid. Nine cases of pneumomediastinum occurred in the setting of suspected iatrogenic perforation after recent surgery or procedure. Six cases had esophageal perforation, and 5 of these had mediastinal fluid. All three cases without perforation also had mediastinal fluid. Eighty-six cases were classified as other and included a variety of clinical histories. This category contained 8 esophageal perforations, 7 of which had mediastinal fluid. One case of mediastinal fluid was not associated with esophageal perforation in this category. CONCLUSION The presence of mediastinal fluid, specifically within the visceral compartment, strongly suggests esophageal injury, and its absence strongly argues against it. An important caveat is in the setting of recent surgery, in which mediastinal fluid can be seen normally. An esophagography study can supplement the evaluation if there is a discrepancy between the clinical suspicion and the original CT findings.

Abstract
Background: The technique of a percutaneous transpedicular biopsy of spinal lesions has been shown to be a useful alternative to paraspinal biopsy for vertebral body lesions in the thoracic and lumbosacral spine. Percutaneous vertebral biopsy is less invasive, cost-effective, and is suitable for patients with intractable back pain and vertebral body lesions that are detected with noninvasive imaging modalities. Objective: The purpose of this study was to establish the diagnostic utility and spectrum of fluoroscopy-guided percutaneous transpedicular biopsies of the thoracolumbar spine performed at our institution. Materials and Methods: This retrospective descriptive study to establish the diagnostic utility and spectrum of percutaneous fluroscopic guided transpedicular biopsy of lower thoracic and lumbar vertebral lesions has been performed on 42 patients in a tertiary care hospital between April 2017 and December 2019. There were 28 male patients and 14 female patients. The mean age was 48 years (range: 12–66 years). There were one 14 thoracic, 26 lumbar, and 2 sacral biopsy specimens. The lesion level was determined under fluoroscopy. Biopsy was taken with a trephine needle under local anesthesia. Accuracy and effectiveness of the technique were analyzed on histopathologic confirmation. Results: The fluoroscopic guided percutaneous transpedicular spine biopsies of 42 patients with spinal pathology were performed through the posterior transpedicular approach percutaneously. Of the 42 patients, 28 were male (66.7%) and 14 were female (33.3%). Vertebral involvement was observed to be more in the lower thoracic region (26.2%), followed by the upper dorsal region (7.1%), L1 (23.6%), L2 (6.4%), L3 (14.6%), L5 (17.3%), and sacrum (4.8%). There were 21 cases with tumor etiology (14 metastasis, 2 malignant round cell tumor, 2 multiple myeloma, and 3 lymphomas), 14 tuberculosis (TB), 4 osteomyelitis, 2 inflammatory, and 1 isolated compression fractures. Twelve patients of the 14 diagnosed cases who were diagnosed with TB on histopathology had positive TB culture and sensitivity pattern. Conclusion: Percutaneous transpedicular fluoroscopy-guided biopsy with a Jamshidi trocar with an internal diameter of 3.1 mm is a simple, safe, and reliable method for the etiological diagnosis of vertebral lesions. The use of this technique, however, is dependent on the accurate placement of the trocar and on close qualified interdisciplinary clinical cooperation. This minimally invasive technique is simple, safe, and effective in the diagnosis of malignant and infective lesions.

Abstract
AIMS To examine the feasibility and safety of a novel protocol for low fluoroscopy, electroanatomic mapping (EAM)-guided Cardiac resynchronization therapy with a defibrillator (CRT-D) implantation and using both EnSite NavX (St. Jude Medical, St. Paul, MN, USA) and Carto 3 (Biosense Webster, Irvine, CA, USA) mapping systems. METHODS AND RESULTS Twenty consecutive patients underwent CRT implantation using either a conventional fluoroscopic approach (CFA) or EAM-guided lead placement with Carto 3 and EnSite NavX mapping systems. We compared fluoroscopy and procedural times, radiopaque contrast dose, change in QRS duration pre- and post-procedure, and complications in all patients. Fluoroscopy time was 86% lower in the EAM group compared to the conventional group [mean 37.2 min (CFA) vs. 5.5 min (EAM), P = 0.00003]. There was no significant difference in total procedural time [mean 183 min (CFA) vs. 161 min (EAM), P = 0.33] but radiopaque contrast usage was lower in the EAM group [mean 16 mL (CFA) vs. 4 mL (EAM), P = 0.006]. Likewise, there was no significant change in QRS duration with BiV pacing between the groups [mean -13 (CFA) vs. -25 ms (EAM), P = 0.09]. CONCLUSION Electroanatomic mapping-guided lead placement using either Carto or ESI NavX mapping systems is a feasible alternative to conventional fluoroscopic methods for CRT-D implantation utilizing the protocol described in this study.

Abstract
Objective To describe and to analyze cervical epidural contrast patterns seen in antero-posterior (AP), contralateral oblique (CLO), and lateral view. To identify factors that might help in predicting contrast distribution pattern and extent. Method Spread of contrast in the cervical epidural space was prospectively studied in AP, lateral, and three CLO views. Results CLO view showed contrast spread of variable thickness with its posterior margin overlying the ventral interlaminar line (VILL). In the lateral view, the spread was also of variable thickness, but the posterior margin of the contrast lay on the spinolaminar line in only 10 of 24 patients. Ventral contrast spread was not visualized in any patient. In the AP view, bilateral spread was seen in 14 of 24 subjects, and nerve root spread was seen in 16 of 24 subjects. No association of the pattern of spread or dispersion was seen to patient age, volume injected, or needle location. Conclusions The CLO view provides a consistent radiological landmark for the posterior margin of contrast in the dorsal epidural space; the lateral view fails to provide such a consistent landmark. The thickness of the spread is variable, both in the CLO and in the lateral view. Thick spread extending into the foramen in the CLO view and over the articular pillars in the lateral view is frequent and should not be misconstrued as subdural or intrathecal spread. In contradistinction to previous studies, true ventral spread was not seen in any patient. When using low volumes, contrast spread is independent of patient age, volume injected, or needle tip location in the AP view.

Abstract
The purpose of this work is to evaluate methods for producing a library of 2D-radiographic images to be correlated to clinical images obtained during a fluoroscopically-guided procedure for automated patient-model localization. The localization algorithm will be used to improve the accuracy of the skin-dose map superimposed on the 3D patient-model of the real-time Dose-Tracking-System (DTS). For the library, 2D images were generated from CT datasets of the SK-150 anthropomorphic phantom using two methods: Schmid's 3D-visualization tool and Plastimatch's digitally-reconstructed-radiograph (DRR) code. Those images, as well as a standard 2D-radiographic image, were correlated to a 2D-fluoroscopic image of a phantom, which represented the clinical-fluoroscopic image, using the Corr2 function in Matlab. The Corr2 function takes two images and outputs the relative correlation between them, which is fed into the localization algorithm. Higher correlation means better alignment of the 3D patient-model with the patient image. In this instance, it was determined that the localization algorithm will succeed when Corr2 returns a correlation of at least 50%. The 3D-visualization tool images returned 55-80% correlation relative to the fluoroscopic-image, which was comparable to the correlation for the radiograph. The DRR images returned 61-90% correlation, again comparable to the radiograph. Both methods prove to be sufficient for the localization algorithm and can be produced quickly; however, the DRR method produces more accurate grey-levels. Using the DRR code, a library at varying angles can be produced for the localization algorithm.

Abstract
AIM The fluoroscopically guided selective nerve root block (SNRB) is being used increasingly as a therapy for radicular pain as well as a diagnostic tool. However, studies and the literature reviews have yet to reach a definite conclusion on the efficacy in this setting. Our aim was to prospectively investigate factors that may affect the success of this procedure. MATERIALS AND METHODS A total of 301 treatment episodes with 283 patients were assessed over 25 months by patient questionnaire over a 7-day period. Changes in analgesic benefit over time, by operating consultant, referring specialty, spinal level, and the presence of periprocedural symptom provocation were evaluated. Statistical analysis was performed by using the χ(2) test, Wilcoxon test, and Kruskal-Wallis rank sum test, and the asymptotic marginal-homogeneity test. P < .05 was considered significant. RESULTS There was a statistically significant increase in pain relief over the 7 days after the procedure. Pain provocation during the procedure did not improve analgesic success. Cervical, lumbar, and sacral level procedures were equally efficacious. The specialist who referred the patient and the use of contrast to verify needle position during the procedure also did not affect the analgesic outcome. Overall, 69.1% of patients experienced some pain relief by day 7. CONCLUSION Analgesic success rates of selective nerve root blocks did not vary with spinal level, or use of contrast or periprocedural replication of symptoms, when using fluoroscopic guidance. Patients may expect a continued significant improvement in their symptoms for at least a week after the procedure.
