RESUMO

Interventional Radiology (IR) was officially approved by the American Board of Medical Specialties in 2012 and the Accreditation Council of Graduate Medical Education as a unique, integrated residency in 2014. Its establishment and distinction from diagnostic radiology was compelled by the increasing emphasis on clinical care delivery by IRs. The shift in the IR training paradigm, as exemplified in the Integrated IR residency programs, appeals to a distinct cohort of applicants, prompting the need to re-evaluate the recruitment and selection process. This article discusses selection criteria for identifying ideal candidates for the new IR training model (focusing on Integrated IR residency training), highlights the importance of collaboration between the IR and DR selection committees, and illustrates the changes made at a single institution over the course of 4 selection cycles prior to the COVID-19 pandemic as well as significant changes in the current climate of the global pandemic.

RESUMO

RATIONALE AND OBJECTIVES: Female physicians in academic medicine have faced barriers that potentially affect representation in different fields and delay promotion. Little is known about gender representation differences in United States academic radiology departments, particularly within the most pursued subspecialties. PURPOSE: To determine whether gender differences exist in United States academic radiology departments across seven subspecialties with respect to academic ranks, departmental leadership positions, experience, and scholarly metrics. MATERIALS AND METHODS: In this cross-sectional study from November 2018 to June 2020, a database of United States academic radiologists at 129 academic departments in seven subspecialties was created. Each radiologist's academic rank, departmental leadership position (executive-level - Chair, Director, Chief, and Department or Division Head vs vice-level - vice, assistant, or associate positions of executive level), self-identified gender, years in practice, and measures of scholarly productivity (number of publications, citations, and h-index) were compiled from institutional websites, Doximity, LinkedIn, Scopus, and official NPI profiles. The primary outcome, gender composition differences in these cohorts, was analyzed using Chi2 while continuous data were analyzed using Kruskal-Wallis rank sum test. The adjusted gender difference for all factors was determined using a multivariate logistic regression model. RESULTS: Overall, 5086 academic radiologists (34.7% women) with a median 14 years of practice (YOP) were identified and indexed. There were 919 full professors (26.1% women, p < 0.01) and 1055 executive-level leadership faculty (30.6% women, p < 0.01). Within all subspecialties except breast imaging, women were in the minority (35.4% abdominal, 79.1% breast, 12.1% interventional, 27.5% musculoskeletal, 22.8% neuroradiology, 45.1% pediatric, and 19.5% nuclear; p < 0.01). Relative to subspecialty gender composition, women full professors were underrepresented in abdominal, pediatric, and nuclear radiology (p < 0.05) and women in any executive-level leadership were underrepresented in abdominal and nuclear radiology (p < 0.05). However, after adjusting for h-index and YOP, gender did not influence rates of professorship or executive leadership. The strongest single predictors for professorship or executive leadership were h-index and YOP. CONCLUSION: Women academic radiologists in the United States are underrepresented among senior faculty members despite having similar levels of experience as men. Gender disparities regarding the expected number of women senior faculty members relative to individual subspecialty gender composition were more pronounced in abdominal and nuclear radiology, and less pronounced in breast and neuroradiology. Overall, h-index and YOP were the strongest predictors for full-professorship and executive leadership among faculty. KEY RESULTS: ● Though women comprise 34.7% of all academic radiologists, women are underrepresented among senior faculty members (26.1% of full professors and 30.6% of executive leadership) ● Women in junior faculty positions had higher median years of practice than their male counterparts (10 vs 8 for assistant professors, 21 vs 13 for vice leadership) ● Years of practice and h-index were the strongest predictors for full professorship and executive leadership.

RESUMO

PURPOSE: To determine demographics, practice patterns, needs from Society of Interventional Radiology (SIR), and preferences of interventional radiologists (IRs) early in their careers. METHODS: A 28-question descriptive survey was used to identify demographic and practice composition, practice issues, and needs of early career IRs. The survey was distributed to SIR members in the United States (US) (n = 859) within the first 8 years of practice, with 213 respondents (25%). RESULTS: Respondents were primarily male (n = 181, 87%), less than 40 years old (n = 156, 73%), in practice for 6 years or less (n = 167, 79%), and satisfied with IR as a career (n = 183, 92.4%). The majority were in academic practice (n = 89, 43.2%) or large private practice group (n = 67, 32.5%). Most respondents read diagnostic imaging daily or weekly (n = 130, 61%). The majority of respondents perform complex procedures regularly including transarterial tumor therapy, percutaneous tumor ablation, peripheral arterial interventions, and biliary interventions monthly. Many respondents (n = 49, 23%) have changed jobs at least once citing career advancement, practice issues/disagreements, or compensation as reason. Most respondents would serve as mentors (n = 170, 80%) for trainees and were satisfied with their career mentorship (n = 166, 78%). Respondents felt that mentorship, identification of barriers facing early career IRs, and networking should be the most important functions of the Early Career Section (ECS)of the SIR. CONCLUSION: As nearly all survey respondents indicated that early career IRs have different needs and priorities than established physicians, they felt that mentorship, identification of barriers facing early career IRs, and networking should be the most important functions of the ECS. Additionally, this same group of IRs report low comfort with the business side of medicine and may benefit from directed content provided by the SIR ECS.

RESUMO

Lymphatics have long been overshadowed by the remainder of the circulatory system. Historically, lymphatics were difficult to study because of their small and indistinct vessels, colorless fluid contents, and limited effective interventions. However, the past several decades have brought increased funding, advanced imaging technologies, and novel interventional techniques to the field. Understanding the history of lymphatic anatomy and physiology is vital to further realize the role lymphatics play in most major disease pathologies and innovate interventional solutions for them.

RESUMO

Traumatic chylothorax occurs more often now than in historic reports. In part, this is due to the increased ability to perform more advanced and aggressive thoracic resections and cardiovascular surgeries as well as the improved mortality of cancer patients. If untreated, chylothorax can result in significant morbidity and mortality, particularly in patients with underlying malignancy. Thoracic duct embolization for chylothorax was the first successful lymphatic intervention and has been performed for over 20 years. An overview of the clinical and technical approach to thoracic duct embolization for traumatic chylothorax is presented in addition to a review of outcomes.

RESUMO

The training paradigm of the interventional radiologist has quickly evolved with the approval of the integrated interventional radiology (IR) residency by the American Board of Medical Specialties and the Accreditation Council of Graduate Medical Education. Prior to appointment in an integrated IR program, a resident must complete a preliminary clinical year, which may be surgical, medical, or transitional. The unique procedural- and clinical-based skillset required of the IR resident is best aligned with a surgical preliminary year. The following is a review of the steps to successful creation of a surgical preliminary year based on a single institution's experience.

RESUMO

Between September 2008 and August 2017, 36 patients (mean age 56 y; range, 30-89 y) underwent transvenous biopsy of suspected tumor thrombus or perivascular tumor. Intravascular biopsy was pursued because of inaccessible percutaneous access in 9 patients (25%) and as part of a planned revascularization procedure in 27 patients (75%). Histopathologic results showed malignancy in 26 patients (72%) and benign etiologies in 10 patients (28%). No patients required repeat biopsy. There were no complications related to the biopsy procedure. The present series suggests that transvenous biopsy is a safe and accurate method of intravascular and perivascular mass tissue sampling.

RESUMO

BACKGROUND: The ATTRACT trial (Acute Venous Thrombosis: Thrombus Removal with Adjunctive Catheter-Directed Thrombolysis) previously reported that pharmacomechanical catheter-directed thrombolysis (PCDT) did not prevent postthrombotic syndrome (PTS) in patients with acute proximal deep vein thrombosis. In the current analysis, we examine the effect of PCDT in ATTRACT patients with iliofemoral deep vein thrombosis. METHODS: Within a large multicenter randomized trial, 391 patients with acute deep vein thrombosis involving the iliac or common femoral veins were randomized to PCDT with anticoagulation versus anticoagulation alone (No-PCDT) and were followed for 24 months to compare short-term and long-term outcomes. RESULTS: Between 6 and 24 months, there was no difference in the occurrence of PTS (Villalta scale ≥5 or ulcer: 49% PCDT versus 51% No-PCDT; risk ratio, 0.95; 95% CI, 0.78-1.15; P=0.59). PCDT led to reduced PTS severity as shown by lower mean Villalta and Venous Clinical Severity Scores ( P<0.01 for comparisons at 6, 12, 18, and 24 months), and fewer patients with moderate-or-severe PTS (Villalta scale ≥10 or ulcer: 18% versus 28%; risk ratio, 0.65; 95% CI, 0.45-0.94; P=0.021) or severe PTS (Villalta scale ≥15 or ulcer: 8.7% versus 15%; risk ratio, 0.57; 95% CI, 0.32-1.01; P=0.048; and Venous Clinical Severity Score ≥8: 6.6% versus 14%; risk ratio, 0.46; 95% CI, 0.24-0.87; P=0.013). From baseline, PCDT led to greater reduction in leg pain and swelling ( P<0.01 for comparisons at 10 and 30 days) and greater improvement in venous disease-specific quality of life (Venous Insufficiency Epidemiological and Economic Study Quality of Life unit difference 5.6 through 24 months, P=0.029), but no difference in generic quality of life ( P>0.2 for comparisons of SF-36 mental and physical component summary scores through 24 months). In patients having PCDT versus No-PCDT, major bleeding within 10 days occurred in 1.5% versus 0.5% ( P=0.32), and recurrent venous thromboembolism over 24 months was observed in 13% versus 9.2% ( P=0.21). CONCLUSIONS: In patients with acute iliofemoral deep vein thrombosis, PCDT did not influence the occurrence of PTS or recurrent venous thromboembolism. However, PCDT significantly reduced early leg symptoms and, over 24 months, reduced PTS severity scores, reduced the proportion of patients who developed moderate-or-severe PTS, and resulted in greater improvement in venous disease-specific quality of life.

RESUMO

N-butyl cyanoacrylate glue is well established as a transcatheter or direct injection embolic agent. Herein, targeted glue embolization was performed by direct needle injection into peripheral portal branches and along the surface of the liver to directly treat actively extravasating portal venous injury. In both cases, hemodynamically unstable patients underwent exploratory laparotomy, which was not able to definitively treat the hemorrhage. Subsequently, emergent visceral angiography and indirect portography revealed active portal phase extravasation. Transhepatic direct needle injection of the peripheral portal active extravasation with glue was successful in both cases and the patients stabilized, demonstrating this as an efficacious salvage approach.

RESUMO

Tetra-amelia is a rare congenital disorder characterized by the absence of limbs. We describe the anesthetic management of a 29-year-old woman with tetra-amelia who underwent general anesthesia for tympanomastoidectomy with meatoplasty for an extensive right ear cholesteatoma. Anesthetic challenges related to tetra-amelia include difficult intravenous access, lack of sites for blood pressure monitoring, and possible difficult airway management due to craniofacial anomalies. Our case report focuses on the complex establishment of iliac artery access for invasive blood pressure monitoring by initially cannulating the carotid artery.

RESUMO

OBJECTIVE: The objective of our study was to report the technique, complications, and clinical outcomes of interventional radiology-operated cholecystoscopy with stone removal for the management of symptomatic cholelithiasis. MATERIALS AND METHODS: Ten (77%) men and three (23%) women (mean age, 65 years) with symptomatic cholelithiasis underwent cholecystostomy followed by interventional radiology-operated cholecystoscopy with stone removal. Major comorbidities precluding cholecystectomy included prior cardiac, pulmonary, or abdominal surgery; cirrhosis; sepsis with hyponatremia; seizure disorder; developmental delay; and cholecystoduodenal fistula. Cholecystostomy access, time between cholecystostomy and cholecystoscopy, endoscopic and fragmentation devices used, technical success, procedure time, fluoroscopy time, complications, length of hospital stay, time between cholecystoscopy and cholecystostomy removal, follow-up, and acute cholecystitis recurrence were recorded. RESULTS: Eleven (85%) patients underwent transhepatic cholecystostomy, and two (15%) patients underwent transperitoneal cholecystostomy. The mean time from cholecystostomy to cholecystoscopy was 151 days. Flexible endoscopy was used in eight (62%) patients, rigid endoscopy in three (23%), and both flexible and rigid in two (15%). Electrohydraulic lithotripsy was used in eight procedures, nitinol baskets in seven, ultrasonic lithotripsy in two, and percutaneous thrombectomy devices in one. Primary technical success was achieved in 11 (85%) patients, and secondary technical success was achieved in 13 (100%) patients. The mean procedure time was 164 minutes, and the mean number of procedures required to clear all gallstones was 1. One (8%) patient developed acute pancreatitis, and one (8%) patient died of gastrointestinal hemorrhage. The median hospital length of stay after cholecystoscopy was 1 day for postoperative monitoring. The mean time between cholecystoscopy and cholecystostomy removal was 39 days. One (8%) patient developed recurrent acute cholecystitis 1095 days after cholecystoscopy. CONCLUSION: Interventional radiology-operated cholecystoscopy may serve as an effective method for percutaneous gallstone removal in patients with multiple comorbidities precluding cholecystectomy.

RESUMO

In the setting of portal hypertension, the body responds by creating portosystemic venous shunts, which may lead to the development of varices. Endoscopic treatment of these varices is often warranted to prevent catastrophic bleeding. During the course of variceal treatment, 1 or more portosystemic shunts may be sacrificed, which may acutely exacerbate portal hypertension and reduce systemic venous return. This report describes percutaneous creation of a mesocaval shunt and balloon-occluded retrograde transvenous obliteration (BRTO) in a patient with cavernous transformation of the portal vein. The patient had previously undergone an unsuccessful attempt at transjugular intrahepatic portosystemic shunt (TIPS) creation with postoperative bleeding requiring splenectomy. As TIPS was not feasible, creation of a percutaneous mesocaval shunt provided an alternate pathway for portosystemic decompression, facilitating safe treatment of gastric varices with BRTO via a gastrorenal shunt. These procedures were performed simultaneously to reduce the risk of variceal bleeding from acute changes in portal venous pressures and redirect blood flow through the shunt to maintain patency. This is the first reported case of combined mesocaval shunt placement and BRTO in a single session.

RESUMO

OBJECTIVE: The objective of our study was to describe an association between the radiographic appearance of distressed intravascular implants and venous stenosis or occlusion and to determine the success of reparative endovascular procedures. MATERIALS AND METHODS: Seventy-eight patients with distressed stents or inferior vena cava (IVC) filters characterized by pursing (short-axis contracture), straightening, longitudinal contraction (long-axis contracture), or fracture were identified from retrospective review of a venous registry for the period from February 2004 to October 2016. Patients originally presented with superior vena cava (SVC) syndrome (n = 25), arm swelling (n = 16), iliocaval thrombosis (n = 21), and lower extremity deep venous thrombosis (n = 16), and stents were initially placed in 65 and filters in 13. Implants were located in the IVC (n = 24), subclavian vein (n = 16), brachiocephalic vein (n = 15), common iliac vein (n = 10), multiple veins (n = 4), axillary vein (n = 4), common femoral vein (n = 3), SVC (n = 1), and internal jugular vein (n = 1). Implants included Wallstents in 63 patients; Smart stents in two patients; and Celect Platinum, Denali, Greenfield, and Trapease IVC filters in two, three, two, and six patients, respectively. Venographic indication, distress type, time from initial normal placement to identification of distress, venographic finding (patent, mild stenosis, high-grade stenosis, or occlusion), treatment, revascularization outcome, and complications were recorded. RESULTS: The mean time to distress was 23 months. Fifty-two (67%) patients underwent venography for symptoms and 26 (33%) for surveillance. Forty-five (58%) implants were pursed; 19 (24%), straightened; nine (12%), contracted; and five (6%), fractured. Venography depicted 48 (62%) high-grade stenoses, 19 (24%) complete occlusions, and six (8%) mild stenoses. Of the 73 patients who underwent an intervention, 29 (40%) underwent angioplasty, 15 (21%) underwent angioplasty and stenting, 15 (21%) underwent sharp recanalization, and five (7%) underwent thrombolysis. Revascularization was successful in 67 (92%). Three minor complications occurred. CONCLUSION: Distressed intravascular implants are associated with high-grade venous stenosis or occlusion. Reparative interventions are usually technically successful.

RESUMO

PURPOSE: To report a transnasal snare technique for retrograde primary jejunostomy placement after surgical gastrojejunostomy. MATERIALS AND METHODS: Two patients underwent the transnasal snare technique for retrograde primary jejunostomy placement. Patients included two females, age 58 and 62. In both patients, a gooseneck snare was inserted in a transnasal fashion. After insertion of the snare into the jejunum, the location was confirmed with ultrasound. The snare was then targeted using a Chiba needle through which a 0.018-inch wire was advanced and snared through the nose. The wire was exchanged for a 0.035-inch Amplatz wire over which the tract was serially dilated followed by insertion of the jejunostomy catheter through a peel-away sheath. Technical success, complications, and follow-up were recorded. RESULTS: Primary jejunostomy placement was technically successful in both patients. No minor or major complications occurred. Both patients received enteral nutrition the day following placement. Follow-up was at 54 and 38 days for patients 1 and 2, respectively. CONCLUSION: The transnasal snare technique provides a novel alternative for primary jejunostomy insertion allowing for targeting of the jejunum with improved procedural success and no complications.

RESUMO

This is a retrospective study of 9 consecutive female patients who underwent ureteral embolization via a "sandwich" technique with two vascular plugs and N-butyl cyanoacrylate glue for ureteral fistulae unresponsive to urinary diversion. Average age was 61 years (range, 39-77 y), average duration of diversion was 48 days (range, 2-120 d), and average follow-up was 11 months (range, 4-23 mo). Seven patients (78%) experienced immediate resolution of urinary leakage, and the other 2 (22%) required unilateral repeat treatment for resolution of leakage. Symptom resolution lasted throughout the follow-up period for all patients. Bilateral internal iliac artery pseudoaneurysms developed in 1 patient and were treated with embolization and stent placement.

RESUMO

Superior vena cava (SVC) syndrome, characterized by facial and arm swelling, is most frequently caused by intrathoracic malignancies. Decompression may be achieved with endovenous stent placement. Polytetrafluoroethylene-covered stents have shown to have higher long-term cumulative patency rates compared with uncovered stents for the treatment of malignant SVC syndrome. Unfortunately, polytetrafluoroethylene-covered stents are not readily available worldwide. Moreover, the existing armamentarium, including balloon-expandable iCAST stents (maximum diameter 10 mm) and heparin-coated Viabahn stent-graft endoprostheses (maximum diameter 13 mm), is too small to adequately treat malignant obstruction of the SVC. This report describes a patient with SVC syndrome and SVC tumor thrombus secondary to recurrent nonseminomatous germ cell carcinoma of the mediastinum treated with a Gianturco Z-stent-fixed modified EXCLUDER abdominal aortic aneurysm iliac limb endoprosthesis.
