Percutaneous glue embolization for recalcitrant iatrogenic portal hemorrhage
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
Issues Most Pressing to Early-Career Interventional Radiologists: Results of a Descriptive Survey
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
Thoracic Endovascular Aortic Repair in the Setting of Compromised Distal Landing Zones
Background: The short-term and intermediate-term outcomes of two distinct approaches to thoracic endovascular aortic repair (TEVAR) for descending aortic aneurysms in patients with compromised distal landing zones are reported. Methods: Fifty-one patients (38 female, average age 72 ± 9 years) underwent 55 TEVARs (2008 to 2018) for aneurysmal disease. Inclusion criteria consisted of TEVAR in a compromised distal landing zone, defined as follows: diameter 3.5 cm or greater; cross-sectional thrombus 50% or greater; or 25% or greater circumferential mural calcification in the 2 cm supraceliac aorta; or tortuosity index of 1.1 or more over the 10 cm supraceliac aorta. Treatment cohorts were (1) TEVAR alone (n = 29), and (2) TEVAR with adjunct consisting of visceral snorkel graft with distal stent extension (n = 20) or EndoAnchors (Medtronic, Minneapolis, MN [n = 6]). Results: Perioperative complication rate was 20%. Thirty-day mortality was 5% including one access-site related intraoperative death and one postoperative death from embolic mesenteric ischemia. Median clinical follow-up was 2.2 years. Intermediate-term outcomes include type 1B endoleaks, 35%; 0.5 cm or more per year maximal aortic diameter growth, 9%; reintervention, 15%; and all-cause mortality, 25%. The distal landing zone diameter increased by 0.3 cm per year in the TEVAR alone cohort; however, it decreased by 0.1 cm per year in the adjunct cohort ( P = .04). Conclusions: Thoracic endovascular aortic repair is a viable alternative for the treatment of thoracoabdominal aortic aneurysms in patients with compromised distal landing zones, although these patients may benefit significantly from the development of branched thoracoabdominal devices. In the interim, the use of TEVAR adjuncts may limit progressive degeneration of the distal landing zone in this patient population
Single-session total endovascular iliocaval reconstruction with stent grafting for the treatment of inferior vena cava agenesis and concurrent iliac venous aneurysm rupture
Iliac venous aneurysms are rare vascular abnormalities that may be manifested by abdominal masses, pelvic tenderness, or hypovolemia and may lead to rupture, thrombosis, pulmonary embolism, paradoxical embolism, or death. Inferior vena cava agenesis, like venous aneurysm, is an uncommon condition that may present with deep venous thrombosis. This report describes a patient with inferior vena cava agenesis and iliac venous aneurysm rupture treated with emergent iliocaval reconstruction and endovascular stent graft placement
Endovascular retrieval of a CardioMEMS heart failure system
As the creation and utilization of new implantable devices increases, so does the need for interventionalists to devise unique retrieval mechanisms. This report describes the first endovascular retrieval of a CardioMEMS heart failure monitoring device. A 20-mm gooseneck snare was utilized in conjunction with a 9-French sheath and Envoy catheter for retrieval. The patient suffered no immediate postprocedural complications but died 5 days after the procedure from multiorgan failure secondary to sepsis.
