RESUMO

The clinical outcomes of patients with non-ST-segment elevation myocardial infarction (NSTEMI) were comparable or even worse than those with ST-segment elevation myocardial infarction (STEMI). Although successful percutaneous coronary intervention (PCI) to the culprit lesions of NSTEMI would improve the clinical outcomes, some PCI require long fluoroscopy time, reflecting the difficulty of PCI. This study aims to find clinical factors associated with long fluoroscopy time in PCI to the culprit lesion of NSTEMI. We included 374 patients and divided those into the conventional fluoroscopy time (n = 302) and long fluoroscopy time (n = 72) groups according to the quintiles of fluoroscopy time. Clinical and angiographic parameters were compared between the two groups. Calcification and tortuosity were significantly more severe in the long fluoroscopy time group than in the conventional fluoroscopy time group. The prevalence of previous coronary artery bypass grafting (CABG) and bifurcation lesions was significantly greater in the long fluoroscopy time group than in the conventional fluoroscopy time group. In the multivariate stepwise logistic regression analysis, previous CABG (odds ratio [OR], 3.368; 95% confidence interval [CI], 1.407-8.064; P = 0.006), bifurcation lesion (OR, 2.407; 95% CI, 1.285-4.506; P = 0.006), excessive tortuosity (versus mild to moderate tortuosity; OR, 4.095; 95% CI, 1.159-14.476; P = 0.029), and moderate to severe calcification (versus none to mild; OR, 5.792; 95% CI, 3.254-10.310; P < 0.001) were significantly associated with long fluoroscopy time. In conclusion, previous CABG, bifurcation, excessive tortuosity, and moderate to severe calcification were associated with long fluoroscopy time. Our study provided a reference for PCI operators to identify the difficulties in PCI to the culprit lesion of NSTEMI.

RESUMO

RATIONALE: Videofluoroscopic swallowing study (VFSS) is a noninvasive radiographic procedure that examines the oral, pharyngeal, and cervical esophageal stages of swallowing. Tracheoesophageal fistula (TEF) is difficult to diagnose depending on its size and location. However, how VFSS can be of benefit in the diagnosis of TEF has not been reported yet. PATIENT CONCERNS: A 64-year-old man who had been tracheostomized post spinal tumor resection surgery at the cervical level 1 to 2, had his tracheostomy tube removed approximately 25 years ago. After decannulation, he reported coughing while swallowing food, foreign sensation in the neck and repeated bouts of pneumonia ever since. DIAGNOSIS: VFSS revealed, for the first time, acquired TEF after tracheostomy decannulation as the cause of repetitive aspiration pneumonia. INTERVENTION: VFSS was performed in this case. OUTCOMES: In the background of suspected TEF based on VFSS results, the patient underwent a computed tomography scan of the chest and airway in the prone position, followed by bronchoscopy, which confirmed the existence of a TEF. He then underwent primary closure of the fistula. The patient had an uneventful recovery and is currently symptom-free 10 months after the surgery. LESSONS: This case alerts clinicians to the possibility of TEF as a diagnosis when the aspirate leaks from the upper esophagus and through the posterior wall of trachea in the esophageal phase of VFSS.

RESUMO

OBJECTIVE. Coupled ECG-electromagnetic (EM) guidance shows promise for use in placement of peripherally inserted central catheters (PICCs) when compared with the classic blind technique. However, ECG-EM guidance has not been appropriately compared with the reference standard of fluoroscopy (FX) guidance. Here, we aimed to compare ECG-EM guidance with FX guidance with regard to the final tip position of PICCs. SUBJECTS AND METHODS. A total of 120 patients (age range, 19-94 years) referred for PICC placement were randomized to the ECG-EM or FX group. All interventions were performed by PICC team members who had the same standardized training and experience. Final tip position was assessed using chest radiography and was classified as optimal, suboptimal, or inadequate requiring repositioning on the basis of the distance from the PICC tip to the cavoatrial junction (CAJ). Statistical analyses were performed using the Mann-Whitney U test for final catheter tip position (mean distance from CAJ) and Fisher and chi-square tests for proportions. RESULTS. PICCs were successfully inserted in 118 patients (53 men and 65 women). Catheter tip positions were optimal or suboptimal in 100% of the FX group and 77.2% of the ECG-EM group. Furthermore, precision of placement was significantly better (p = .004) in the FX group (mean distance from the PICC tip to the CAJ = 0.83 cm) than in the ECGEM group (mean distance from the PICC tip to the CAJ = 1.37 cm). Thirteen (22.8%) of the PICCs placed using ECG-EM guidance, all of which were inserted from the left side, were qualified as inadequate requiring repositioning and required another intervention. CONCLUSION. Our results revealed significant differences in final tip position between the ECG-EM and FX guidance techniques and indicate that ECG-EM guidance cannot appropriately replace FX guidance among unselected patients. However, ECGEM guidance could be considered as an acceptable technique for patients in whom the PICC could be inserted from the right side. TRIAL REGISTRATION. ClinicalTrials.gov NCT03652727.

RESUMO

BACKGROUND: Robotic-assistance in endovascular intervention represents a nascent yet promising innovation. OBJECTIVE: To present the first human experience utilizing robotic-assisted angiography in the extracranial carotid circulation. METHODS: Between March 2019 and September 2019, patients with extracranial carotid circulation pathology presenting to Houston Methodist Hospital were enrolled. RESULTS: A total of 6 patients met inclusion criteria: 5 underwent diagnostic angiography only with robotic-assisted catheter manipulation, while 1 underwent both diagnostic followed by delayed therapeutic intervention. Mean age was 51 +/- 17.5 yr. Mean anesthesia time was 158.7 +/- 37.9 min, mean fluoroscopic time was 22.0 +/- 7.3 min, and mean radiation dose was 815.0 +/- 517.0 mGy. There were no technical complications and no clinical deficits postprocedure. None of the cases required conversion to manual neurovascular intervention (NVI). CONCLUSION: Incorporating robotic technology in NVI can enhance procedural technique and diminish occupational hazards. Its application in the coronary and peripheral vascular settings has established safety and efficacy, but in the neurovascular setting, this has yet to be demonstrated. This study presents the first in human feasibility experience of robotic-assisted NVI in the extracranial carotid circulation.

RESUMO

BACKGROUND: Intraoperative localization of the correct spine level can be challenging when dealing with the thoracic spine; especially in morbidly obese patients and in mid-thoracic spine lesions. Different radiological reference markers techniques for dorsal surgery have been reported without a clear DAP (effective dose), localization and surgical time analysis. PURPOSE: The aim of the study is to analyze the radiological reference markers technique in terms of localization time and radiation dose during surgery for dorsal lesions. METHODS: We used a radiopaque marker (fiducial) directly positioned before surgery over the lamina or the spinous process using CT scan for precise localization and vertebra count. We prospectively collected data about patients who underwent preoperative thoracic localization between April 2015 and September 2018 at Neurosurgery Department of Ferrara University Hospital. Clinical data as pathology, related surgical technique, radiological exams, localization time and radiation exposure were analyzed. RESULTS: 19 patients who underwent preoperative radiopaque marker (fiducial) positioning and 11 patients who underwent fluoroscopy technique were enrolled. No complications related to fiducial placement and no wrong-level occurred. The localization time with the fiducial was reduced dramatically (3 min vs 15 min of the standard technique). The average DAP (effective dose) for the fiducial group was 20 Gy-cm2 compared with 16 Gy-cm2 of the traditional group. CONCLUSION: The use of preoperative fiducial for intraoperative localization of the target level in the thoracic spine dramatically reduce the location time without a significantly higher DAP (effective dose).

RESUMO

BACKGROUND AND PURPOSE: Visualization in neuroendovascular intervention currently relies on biplanar fluoroscopy and contrast administration. With the advent of endoscopy, direct visualization of the intracranial intravascular space has become possible with microangioscopes. We analyzed the efficacy of our novel microangioscope to enable direct observation and inspection of the cerebrovasculature, complementary to a standard fluoroscopic technique. MATERIALS AND METHODS: Iterations of microangioscopes were systematically evaluated for use in neurodiagnostics and neurointerventions in both live animal and human cadaveric models. Imaging quality, trackability, and navigability were assessed. Diagnostic procedures assessed included clot identification and differentiation, plaque identification, inspection for vessel wall injury, and assessment of stent apposition. Interventions performed included angioscope-assisted stent-retriever thrombectomy, clot aspiration, and coil embolization. RESULTS: The microangioscope was found helpful in both diagnosis and interventions by independent evaluators. Mean ratings of the imaging quality on a 5-point scale ranged from 3.0 (clot identification) to 4.7 (Pipeline follow-up). Mean ratings for clinical utility ranged from 3.0 (aspiration thrombectomy) to 4.7 (aneurysm treatment by coil embolization and WEB device). CONCLUSIONS: This fiber optic microangioscope can safely navigate and visualize the intravascular space in human cadaveric and in vivo animal models with satisfactory resolution. It has potential value in diagnostic and neurointerventional applications.

RESUMO

AIM: To compare the efficacies of fluoroscopy- and ultrasound (US)-guided caudal epidural steroid injections (CESIs) in patients with chronic low back pain (LBP). MATERIAL AND METHODS: This study included patients with chronic LBP who underwent US- (Group U; n = 90) or fluoroscopyguided (Group F; n = 90) CESI. The procedure time, successful injection rate on the first attempt, complication rate, Oswestry Disability Index (ODI) score, and Numeric Rating Scale (NRS) score before CESI and after 3 weeks and 3 months of CESI were analyzed. RESULTS: NRS and ODI scores improved at 3 weeks (p < 0.001) and 3 months (p < 0.001) after CESIs. No significant differences were noted between the two groups for the NRS (p=0.22 and p=0.47) and ODI (p=0.58, p=0.22) scores. Moreover, the CESI procedure time was significantly shorter (p < 0.001) and the successful injection rate on the first attempt was significantly higher (p=0.002) in Group U than in Group F. The complication rate difference was statistically insignificant between the two groups (p > 0.05). CONCLUSION: Outcomes of US-guided CESI were superior than those of fluoroscopy-guided CESI considering the successful injection rate on the first attempt and procedure time. In addition, US-guided CESI was as effective as fluoroscopy-guided CESI and did not expose patients and practitioners to radiation.

RESUMO

OBJECTIVE: Mini C-arm fluoroscopes are widely used by orthopaedic surgeons for intraoperative image guidance without the need for radiographers. This puts the responsibility for radiation exposure firmly with the operating surgeon. In order to maintain safe and best practice under U.K. Ionising Radiation (Medical Exposure) Regulations, one must limit radiation exposure and audit performance using national diagnostic reference levels (DRLs). In the case of the mini C-arm, there are no national DRLs. IR(ME)R, therefore, require the establishment of local DRLs by each hospital to act as an alternative guideline for safe radiation use. The aim of our audit was to establish local DRLs based on our experience operating with the use of the mini C-arm over the last 7 years. METHODS: This retrospective audit evaluates the end dose-area product (DAP) recorded for common trauma and orthopaedic procedures using the mini C-arm in a busy district general hospital.We present the quartile data and have set the cut-off point as the third quartile for formulating the local DRLs, consistent with the methodology for the conventional fluoroscope. RESULTS: For our data set (n = 1664), the third quartile DAP values were lowest for surgeries to the forearm (5.38 cGycm2), hand (7.62 cGycm2), and foot/ankle (8.56 cGycm2), and highest for wrist (10.64 cGycm2) and elbow (14.61 cGycm2) procedures. ADVANCES IN KNOWLEDGE: To our knowledge, this is the largest data set used to establish local DRLs. Other centres may find our guidelines useful whilst they establish their own local DRLs.

RESUMO

Intraoperative localization within the thoracic spine in the prone position may be particularly difficult on account of absence of common landmarks such as the sacrum or the C2 vertebra, thus increasing the potential for wrong-level surgery that may lead to patient morbidity and potential litigation. Some current localization methods involve implantation of markers that are invasive and serve to add to procedural expense while yet still failing to entirely eliminate errors. We describe a novel, non-invasive, and inexpensive technique for intraoperative localization of the thoracic spine in the prone position using an esophageal temperature probe. Following patient positioning, anteroposterior fluoroscopy is used to localize the radiopaque tip of the esophageal probe relative to the thoracic spine. After determining the probe tip's location, it becomes the counting reference for all subsequent intraoperative fluoroscopic localizations during surgery. As the probe tip is generally visible in the same fluoroscopic image as the surgical level, error from parallax created when moving the fluoroscopy machine from an anatomic landmark either above or below is avoided and a shorter fluoroscopy time is needed. Use of an esophageal temperature probe as a landmark in localizing spinal level may serve as a reliable and It offers a safe, reliable, and inexpensive technique for proper localization of thoracic spine levels.

RESUMO

Prediction of aspiration pneumonia development in at-risk patients is vital for implementation of appropriate interventions to reduce morbidity and mortality. Unfortunately, studies utilizing a comprehensive approach to risk assessment are still lacking. The objective of this study was to analyze the clinical features and videofluoroscopic swallowing study (VFSS) findings that predict aspiration pneumonia in patients with suspected dysphagia.Medical records of 916 patients who underwent VFSS between September 2014 and June 2018 were retrospectively analyzed. Patients were divided into either a pneumonia group or a non-pneumonia group based on diagnosis of aspiration pneumonia. Clinical information and VFSS findings were evaluated.One hundred seven patients (11.7%) were classified as having pneumonia. Multivariate analysis indicated that aspiration during the 2- cubic centimeter thick-liquid trial of VFSS (odds ratio [OR] = 3.23, 95% confidence interval [CI]: 1.93-5.41), smoking history (OR = 2.63, 95% CI: 1.53-4.53), underweight status (OR = 2.27, 95% CI: 1.31-3.94), abnormal pharyngeal delay time (OR = 1.60, 95% CI: 1.01-2.53), and a Penetration-Aspiration Scale level of 8 (OR = 3.73, 95% CI: 2.11-6.59) were significantly associated with aspiration pneumonia development. Integrated together, these factors were used to develop a predictive model for development of aspiration pneumonia (DAP), with a sensitivity of 82%, specificity of 56%, and an area under the receiver operating characteristic curve of 0.73.The best predictors for DAP included videofluoroscopic findings of aspiration during a 2-cubic centimeter thick-liquid trial, prolonged pharyngeal delay time, a Penetration-Aspiration Scale level of 8, history of smoking, and underweight status. These 5 proposed determinants and the associated DAP score are relatively simple to assess and may constitute a clinical screening tool that can readily identify and improve the management of patients at risk for aspiration pneumonia.

Para recolocarlo se ha propuesto realizar la maniobra alfa, que consiste en devolver al catéter a su correcta posición a través de unas guías rígidas bajo control fluoroscópico. El objetivo del presente estudio es analizar los 107 procedimientos realizados en nuestro Centro tratando de determinar factores que puedan predecir el éxito de la técnica. MATERIAL Y MÉTODOS: El método de la maniobra alfa fue utilizado en 86 pacientes con un total de 107 procedimientos (en 70 pacientes solo una maniobra, en 16 pacientes dos maniobras o más). RESULTADOS: El éxito global de la técnica fue de un 60%. La tasa de éxito no mostró diferencias en cuanto al sexo (60% en varones frente a 40% mujeres, p = 0,104), tiempo de fallo del catéter (fallos precoces 60% frente a fallos tardíos 62%, p = 0,849), tipo de catéter (75% en autoposicionantes frente a 58% en espirales, p = 0,633), ni en cuanto a la posición inicial del catéter. Sólo hubo un caso de peritonitis secundaria al procedimiento. CONCLUSIONES: La maniobra alfa es un método eficaz y seguro en la corrección de la malposición del catéter peritoneal


INTRODUCTION AND OBJECTIVES: Peritoneal catheter displacement is one of the most common complications of peritoneal dialysis. The alpha manoeuvre has been proposed as a repositioning technique, which involves returning the catheter to its correct position using rigid guidewires under fluoroscopic guidance. The aim of this study is to analyse the 107 procedures performed at our Centre to identify factors that may predict the success of the technique. MATERIAL AND METHODS: The alpha manoeuvre method was used in 86 patients, with a total of 107 procedures (70 patients underwent one manoeuvre only, 16 patients underwent two or more manoeuvres). RESULTS: The overall success rate of the technique was 60%. There were no differences in success rate in terms of gender (60% male vs. 40% female, p = 0.104), time of catheter failure (early 60% vs. late 62%, p = 0.849), type of catheter (75% self-locating vs. 58% spiral, p = 0.633) or the initial position of the catheter. There was only one case of peritonitis related to the procedure. CONCLUSIONS: The alpha manoeuvre is an effective and safe method for correcting peritoneal catheter displacement

RESUMO

BACKGROUND: In recent years, transbronchial cryobiopsy (TBCB) has come to be increasingly used in interventional pulmonology units as it obtains larger and better-quality samples than conventional transbronchial lung biopsy (TBLB) with forceps. No multicenter studies have been performed, however, that analyse and compare TBCB and TBLB safety and yield according to the interstitial lung disease (ILD) classification. OBJECTIVES: We compared the diagnostic yield and safety of TBCB with cryoprobe sampling versus conventional TBLB forceps sampling in the same patient. METHOD: Prospective multicenter clinical study of patients with ILD indicated for lung biopsy. Airway management with orotracheal tube, laryngeal mask and rigid bronchoscope was according to the protocol of each centre. All procedures were performed using fluoroscopy and an occlusion balloon. TBLB was followed by TBCB. Complications were recorded after both TBLB and TBCB. RESULTS: Included were 124 patients from 10 hospitals. Airway management was orotracheal intubation in 74% of cases. Diagnostic yield according to multidisciplinary committee results for TBCB was 47.6% and for TBLB was 19.4% (p<0.0001). Diagnostic yield was higher for TBCB compared to TBLB for two groups: idiopathic interstitial pneumonias (IIPs) and ILD of known cause or association (OR 2.5; 95% CI: 1.4-4.2 and OR 5.8; 95% CI: 2.3-14.3, respectively). Grade 3 (moderate) bleeding after TBCB occurred in 6.5% of patients compared to 0.8% after conventional TBLB. CONCLUSIONS: Diagnostic yield for TBCB was higher than for TBLB, especially for two disease groups: IIPs and ILD of known cause or association. The increased risk of bleeding associated with TBCB confirms the need for safe airway management and prophylactic occlusion-balloon use.

RESUMO

Management of musculoskeletal (MSK) tumours has traditionally been delivered by surgeons and medical oncologists. However, in recent years, image-guided interventional oncology (IO) has significantly impacted the clinical management of MSK tumours. With the rapid evolution of relevant technologies and the expanding range of clinical indications, it is likely that the impact of IO will significantly grow and further evolve in the near future.In this narrative review, we describe well-established and new interventional technologies that are currently integrating into the IO armamentarium available to radiologists to treat MSK tumours and illustrate new emerging IO indications for treatment.

RESUMO

To compare outcomes of ultrasound guidance (USG) versus fluoroscopy roadmap guidance (FG) angiography for femoral artery access in patients who underwent transfemoral (TF) transcatheter aortic valve implantation (TAVI) to determine whether routine USG use was associated with fewer vascular complications. Vascular complications are the most frequent procedural adverse events associated with TAVI. USG may provide a decreased rate of access site complications during vascular access compared with FG. Patients who underwent TF TAVI between July 2012 and July 2017 were reviewed and outcomes were compared. Vascular complications were categorized by Valve Academic Research Consortium-2 criteria and analyzed by a multivariable logistic regression adjusting for potential confounding risk factors including age, gender, body mass index, peripheral vascular disease, Society of Thoracic Surgeons score and sheath to femoral artery ratio. Of the 612 TAVI patients treated, 380 (63.1%) were performed using USG for access. Routine use of USG began in March 2015 and increased over time. Vascular complications occurred in 63 (10.3%) patients and decreased from 20% to 3.9% during the study period. There were fewer vascular complications with USG versus FG (7.9% vs 14.2%, p = 0.014). After adjusting for potential confounding risk factors that included newer valve systems, smaller sheath sizes and lower risk patients, there was still a 49% reduction in vascular complications with USG (odds ratio 0.51, 95% confidence interval 0.29 to 0.88, p = 0.02). In conclusion, USG for TF TAVI was associated with reduced vascular access site complications compared with FG access even after accounting for potential confounding risk factors and should be considered for routine use for TF TAVI.

RESUMO

INTRODUCTION: Recent studies have shown that His-bundle pacing could be an alternative in patients requiring cardiac resynchronization therapy as it is comparable or better in terms of amelioration of ventricular activation, narrowing of the QRS complex, or clinical outcomes. However, in case of high threshold at the level of His-bundle or inability to correct conduction through a diseased His-Purkinje system other option should be searched like left bundle pacing. PATIENT CONCERNS: A 77-year-old man presented to the Emergency Department for dizziness and dizziness and lightheadedness due to an intermittent 2:1 atrioventricular block with a QRS complex morphology of a major left branch block. DIAGNOSIS: Given the documented symptomatic 2:1 AV block, according to the European Guideliness the patient was considered to have a class 1 indication of permanent double chamber cardiostimulation. INTERVENTIONS: A lead delivery system with a C315 His catheter and a Select Secure 3830 69 cm pacing lead were placed at the His bundle area with important narrowing of the QRS complex but with an unacceptable high threshold. The delivery system was moved towards the apex 1,5 cm and the lead screwed deep into the septum until capture of the left bundle branch was achieved with complete normalization of the conduction troubles. OUTCOMES: At 3 month follow-up the patient was asymptomatic and the pacing and sensing thresholds remained at same values as during implantation: 0.75/0.4 ms and 14 mV respectively. CONCLUSION: Left bundle-pacing represents the next step of His-Purkinje system pacing to overcome all difficulties related to His-bundle pacing.

RESUMO

BACKGROUND: The aims of this study were to identify the predictive factors for microbiological diagnosis through disco-vertebral biopsy (DVB) in patients with pyogenic vertebral osteomyelitis (PVO) and negative blood cultures, and compare the performance of DVB under fluoroscopic versus scanographic guidance. METHODS: We performed a cohort study comparing positive and negative DVB among patients with PVO. All cases of PVO undergoing a DVB for microbiological diagnosis in our center were retrospectively reviewed. Infections due to Mycobacterium tuberculosis, infections on foreign device, and non-septic diseases were excluded. Anamnestic, clinical, biological, microbiological, as well as radiological data were collected from medical charts thanks to a standardized data set. RESULTS: A total of 111 patients were screened; 88 patients were included. Microbiological cultures were positive in 53/88 (60.2%) patients. A thickening of the paravertebral tissue ≥10 mm on magnetic resonance imaging (MRI) in axial MR scans was a predictive factor of DVB microbiological positivity (52.4% vs. 13.3%; p = 0.006; OR = 5.4). Overall, 51 DVB were performed under fluoroscopic guidance and 37 under scanographic guidance. Considering lumbar DVB, 25/36 (69.4%) of cases yielded positive results under fluoroscopic guidance versus 5/15 (33.3%) under scanographic guidance (p = 0.02; OR = 4.4). No adverse event linked to DVB was notified. CONCLUSION: Every patient with PVO and negative blood cultures should undergo a DVB. A thickening of the paravertebral tissue ≥10 mm on MRI is associated with a higher rate of positive DVB culture. A lumbar DVB under fluoroscopic guidance is more sensitive than under scanographic guidance to identify the micro-organism involved.

RESUMO

BACKGROUND: Computer navigation technology is gradually applied to the placement of pedicle screws, but its security and effectiveness still lack of high-quality evidence-based medical evidence. In this study, we will perform a systematic review of previously published randomized controlled trials to investigate the accuracy and effectiveness of computer navigation vsersus fluoroscopy guidance for pedicle screw placement. METHODS: All study protocols adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. PubMed (MEDLINE), The excerpta medica database, Web of Science (science and social science citation index), The Cochrane Library (Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials (CENTRAL), Cochrane Methodology Register), China National Knowledge Infrastructure, Chinese Science and Technology Periodical Database, WanFang, Chinese Biomedical Literature Database will be searched for relevant articles up to 18 April, 2020. We will include randomized controlled trials of computer navigation and fluoroscopy guidance for pedicle screw placement. The Cochrane Handbook (v6) will be used for assessment of study bias and reliability, and a meta-analysis will be performed using STATA 16.0. The main outcome will be the proportion of accurate implanted screws. Additional outcomes including: overall complication rate, radiation dosage, length of surgery, length of stay, estimated blood loss. RESULTS: The quality of the assessments will be assessed through Grading of Recommendations Assessment, Development, and Evaluation. Data will be disseminated through publications in peer-reviewed journals. CONCLUSION: We will evaluate the accuracy and other perioperative parameters between computer navigation and fluoroscopy guidance for pedicle screw placement.
