Project description:Pulmonary embolism represents a common life-threatening condition. Prompt identification and treatment of this pathological condition are mandatory. In cases of massive pulmonary embolism and hemodynamic instability or right heart failure, interventional radiology treatment for pulmonary embolism is emerging as an alternative to medical treatment (systemic thrombolysis) and surgical treatment. Interventional radiology techniques include percutaneous endovascular catheter directed therapies as selective thrombolysis and thrombus aspiration, which can prove useful in cases of failure or infeasibility of medical and surgical approaches.

Project description:Pulmonary embolism (PE) is a common disease associated with high morbidity and mortality. Currently, guidelines recommend systemic thrombolysis in patients with haemodynamic instability (high-risk PE) or patients with intermediate-high-risk PE with haemodynamic deterioration. Nevertheless, more than half of high-risk PE patients do not receive systemic thrombolysis due to a perceived increased risk of bleeding. In these cases, percutaneous catheter-directed therapy (CDT) or surgical embolectomy should be considered. CDT has emerged and appears to be an effective alternative in treating PE, with a hypothetical lower risk of bleeding than systemic thrombolysis, acting directly in the thrombus with a much lower dose of thrombolytic drug or even without thrombolytic therapy. CDT techniques include catheter-directed clot aspiration or fragmentation, mechanical embolectomy, local thrombolysis, and combined pharmaco-mechanical approaches. A few observational prospective studies have demonstrated that CDT improves right ventricular function with a low rate of haemorrhage. Nevertheless, the evidence from randomised controlled trials is scarce. Here we review different scenarios where CDT may be useful and trials ongoing in this field. These results may change the upcoming guidelines for management and treatment of PE, establishing CDT as a recommended treatment in patients with acute intermediate-high-risk PE.

Project description:Interventional radiologists are playing an increasingly important role in pediatric urologic intervention, working closely with the pediatric urologist. Interventional radiologists are frequently asked to establish percutaneous access to the renal collecting system prior to nephrolithotomy. Additionally, procedures such as percutaneous nephrostomy, ureteral stent placement and exchange, and renal parenchymal biopsy are frequently encountered requests. This article will review these common procedures and highlight techniques and pathology that are unique to the pediatric population.

Project description:Intrahepatic cholangiocarcinoma is a highly aggressive malignancy with an increasing incidence in recent years. Prognosis is poor and most patients are not eligible for resection at the time of initial diagnosis due to the anatomic location, inadequate hepatic reserve, limiting comorbidities or metastatic disease. Several locoregional therapies from the field of interventional radiology exist for patients who are not amenable for surgery, or in case of local recurrence as a single treatment modality or combined with systemic treatment. To date, evidence is limited, with most conclusions drawn from single-center studies with small patient cohorts, often treated in the salvage situation or for local recurrence after initial resection. Nevertheless, the results are promising and suggest a survival benefit in selected patients. This narrative review focuses on the use of different locoregional treatment options for intrahepatic cholangiocarcinoma.

Project description:Pancreatic ductal adenocarcinoma (PDAC) is a lethal disease; patients' long-term survival is strictly linked to the surgical resection of the tumor but only a minority of patients (2-3%) have a resectable disease at diagnosis. In patients with surgically unresectable disease, interventional radiology is taking on an increasing role in treatment with the application of loco-regional percutaneous therapies. The primary purposes of this narrative review are to analyze the safety and efficacy of ablative techniques in the management of borderline resectable and locally advanced diseases and to underline the role of the interventional radiologist in the management of patients with distant metastases. The secondary purpose is to focus on the synergy between immunotherapy and ablative therapies.

Project description:Pulmonary embolism (PE) frequently presents a diagnostic and therapeutic challenge in the clinical practice. Established diagnostic algorithms enable the prevention of unnecessary use of imaging with ionizing radiation, so that now standardized algorithms could also be validated in pregnant patients with suspected acute PE. In risk stratification the assessment of the right ventricle plays a decisive role in addition to clinical parameters, especially if early discharge and outpatient treatment of PE is an option. Direct oral anticoagulants are currently the first-line treatment for the majority of patients with PE, whereas reperfusion treatment following discussion in the interdisciplinary PE team is indicated for those with overt or imminent decompensation. Systematic follow-up observation and care of patients with PE is emphasized in order to decide on the extension or termination of anticoagulation and for detection and treatment of late sequelae, such as chronic thromboembolic pulmonary hypertension.

Project description:PURPOSE:Integrated interventional radiology (IR) residencies recently underwent their second year in the match, the first year of which involved only a limited number of programs. Now that students can choose to enter IR directly, student perceptions of IR vs diagnostic radiology (DR) are of paramount importance. METHODS:We surveyed first- through fourth-year medical students and radiology residents regarding interest in IR vs DR. RESULTS:Students considering a radiological career expressed more interest in IR than DR. Conversely, residents expressed more interest in DR. CONCLUSIONS:Medical student advisors and IR programs should continue to anticipate a high number of applications for integrated IR positions.

Project description:BackgroundHealthcare is a highly polluting industry and attention to the need for making this sector more sustainable is growing. The interventional radiology (IR) department is a relatively unique department in the hospital because of its synergetic use of both imaging equipment and medical instruments. As a result, the interventional radiology department causes a significant environmental burden in terms of energy usage, waste and water pollution. The aim of this study was to explore the current state of sustainability within IR by conducting a survey and interviews among IR specialists in the Netherlands.ResultsThe main findings of this study were that there is a high awareness for the need of sustainability within IR, but that there is still limited action. Previous studies point towards the various opportunities in the field of energy, waste and water pollution, yet our study unveils these opportunities are often not implemented because of (1) sustainability not being a priority, (2) a dependency on employees, and (3) factors that simply cannot be changed by an individual IR department or hospital. Generally, our study indicates that there is a willingness to become more sustainable, but that the current system involves a wide range barriers that hinder true change. Furthermore, it seems that no one is currently taking the lead and a leading role from higher management, government, healthcare authorities or professional societies is lacking.ConclusionsDespite the hurdles found in our study, IR departments can implement several improvements. An important factor is that sustainability should not lead to lower convenience for employees, which can be ensured by a sufficiently designed waste infrastructure and behavioral nudges. Furthermore, there lies an opportunity in more collaboration between IR departments in knowledge sharing and open innovation.

Project description:Interventional radiologists employ a wide variety of drugs on a daily basis to improve patient experiences and outcomes during interventional procedures. The expectation is for the interventionalist to be well-versed in all pharmaceuticals used in the interventional suite. In this article, the authors review the following classes of common miscellaneous pharmaceutical agents used in interventional radiology: vasodilators, vasoconstrictors, antiemetics, bowel antiperistalsis agents, and prothrombotics.

Project description:BACKGROUND:Sialorrhea is common in children with neurological disorders and leads to social isolation, aspiration pneumonia and increased caregiver burden. Sialorrhea management includes anticholinergic medications and a variety of surgeries, but these are limited by side effects, recurrence and risks. OBJECTIVE:We present our method of salivary gland ablation, an interventional radiology treatment for sialorrhea, and report safety and efficacy data from pediatric patients who underwent salivary gland ablation. MATERIALS AND METHODS:Salivary gland ablation uses image-guided sotradecol and ethanol dual-drug injection into the salivary glands. Submandibular and sublingual glands are injected percutaneously using ultrasound. Parotid glands are injected retrograde through Stensen ducts using fluoroscopy. We conducted a retrospective review of the medical records of patients who underwent salivary gland ablation at our institution between 2005 and 2019. Pre- and post-procedure Drooling Frequency and Drooling Severity (DFDS) scale scores were compared and caregiver satisfaction was assessed. We devised two cohorts, one to study patient safety and a subcohort to study clinical efficacy using DFDS scores. RESULTS:One hundred and seventy salivary gland ablation procedures were performed in the 99 patients comprising the safety cohort. Of the procedures, 88.8% resulted in no or minimal complications. Respiratory difficulty, temporary nerve palsy and infection represent the majority of the 11.2% of patients who experienced periprocedural complications. There were no complications resulting in permanent sequelae. Twenty-seven patients met our inclusion criteria for the efficacy subcohort with a mean follow-up time of 5.4 years. DFDS at follow-up decreased from a median score of nine to a seven post-procedure (P=0.000018). The proportion of caregivers who were satisfied with the procedure increased as more glands were ablated, which suggests a causal link between the number of glands ablated and the outcome. CONCLUSION:Salivary gland ablation is a safe and effective procedure with the potential for permanent decrease in symptoms related to sialorrhea.
