Endovascular Repair of Zone 0 Ascending Aortic Aneurysm: A Review of Current Knowledge and Developing Technology.

Aortic aneurysms represent the 15 leading cause of death in men and women over 55 years of age. Where historically these lesions were all addressed via an open approach, endovascular aortic repair has entirely altered the way that surgeons approach aortic lesions. Although it was initially employed for patients who were poor surgical candidates, endovascular repair is now standard for abdominal aortic aneurysms and aneurysms in the descending thoracic aorta.

Gunshot wound causing thoracic aortic injury with bullet embolization to the common femoral artery.

Penetrating traumatic aortic injury (PTAI) is increasing in prevalence given the rise in firearm violence in the United States and is associated with significant morbidity and mortality. These injuries often result in hemorrhagic shock, with patients presenting in extremis or pulseless, traditionally requiring open approaches for repair. A rare but potentially devastating complication of firearm-related PTAI is bullet embolization.

Higher In-Hospital Mortality among Asian Americans Undergoing Transjugular Intrahepatic Portosystemic Shunt Procedure.

Background: Transjugular intrahepatic portosystemic shunt (TIPS) is a procedure to alleviate portal hypertension in patients with decompensated liver cirrhosis. While prior research highlighted racial disparities in TIPS, Asian Americans were not included in the investigation. This study aimed to investigate disparities in the immediate postprocedural outcomes among Asian American patients who underwent TIPS.

Evaluating outcomes of transjugular intrahepatic portosystemic shunt procedure among Native Americans.

Background: This study aims to explore racial disparities in immediate outcomes of Transjugular Intrahepatic Portosystemic Shunt (TIPS) among Native Americans, a group that have higher prevalence of liver cirrhosis but were the "invisible group" in previous TIPS studies due to their small population size.

Methods: The study identified Native Americans and Caucasians who underwent TIPS in National/Nationwide Inpatient Sample (NIS) database from Q4 2015-2020. Preoperative factors, including demographics, indications for TIPS, comorbidities, etiologies for liver disease, primary payer status, and hospital characteristics, were matched by 1:5 propensity score matching.

Higher risk of in-hospital mortality and hepatic encephalopathy during weekend admission in Transjugular Intrahepatic Portosystemic Shunt procedure.

Objectives: Transjugular intrahepatic portosystemic shunt (TIPS) is a procedure used to alleviate portal hypertension in patients with decompensated liver cirrhosis. The weekend effect refers to a higher risk of adverse outcomes associated with procedures performed on weekends compared to weekdays. The goal of this study is to determine whether a weekend effect is evident in TIPS procedures.

Background: Transjugular intrahepatic portosystemic shunt (TIPS) is a procedure used to alleviate patients with chronic liver cirrhosis and portal hypertension. Racial disparities were present in TIPS where numerous studies suggested African American patients experience higher in-hospital mortality rates. However, the incidence of post-TIPS surgical complications, such as HE, has yet to be examined among African Americans.

Advanced chronic renal disease is an independent risk factor for inpatient mortality following transjugular intrahepatic portosystemic shunt procedure.

Background: Transjugular intrahepatic portosystemic shunt (TIPS) is a procedure used to alleviate portal hypertension in patients with decompensated liver cirrhosis. However, the risks and outcomes associated with TIPS in patients with advanced chronic kidney disease (CKD) remain uncertain. This study aimed to investigate the perioperative outcomes of TIPS procedures in patients with advanced CKD using the National Inpatient Sample (NIS) database, a comprehensive all-payer inpatient database in the US.

Tunneled Dialysis Catheters: Perspective from a Single Interventional Radiology Center.

Tunneled dialysis catheters (TDCs) serve as vascular access for hemodialysis (HD) or plasmapheresis. This study examines the frequency and indications for TDC placement and removal by an interventional radiology service over a 5-year period. Indications for catheter placement ( = 289) included HD for patients with end stage kidney disease (65%) or acute kidney injury (AKI, 24%), and plasmapheresis (11%).

Reintervention Rate After Pigtail Catheter Insertion Compared to Surgical Chest Tubes.

Background: Prior studies suggest similar efficacy between large-bore chest tube (CT) placement and small-bore pigtail catheter (PC) placement for the treatment of pleural space processes. This study examined reintervention rates of CT and PC in patients with pneumothorax, hemothorax, and pleural effusion.

Methods: This retrospective study examined patients from September 2015 through December 2020.

Immediate and delayed migration of Onyx embolisation into the renal collecting system.

We present a case of Onyx embolisation of a renal pseudoaneurysm following partial nephrectomy with collecting system involvement with subsequent migration of Onyx into the renal collecting system resulting in renal obstruction. This occurred both immediately after embolisation and again 8 years after embolisation. Both cases required ureteroscopic surgical intervention.

Outcomes of Stroke Thrombectomy Performed by Interventional Radiologists versus Neurointerventional Physicians.

Purpose: To test the hypothesis that interventional radiologists (IRs) and neurointerventional (NI) physicians have similar outcomes of endovascular stroke thrombectomy (EVT), which could be used to improve the availability of thrombectomy.

Materials And Methods: Eight hospitals providing EVT performed by IRs and NI physicians at the same institution submitted sequential retrospective data limited to the era of modern devices. Good clinical outcomes (a 90-day modified Rankin score [mRS] of 0-2) and technically successful revascularization (a modified thrombolysis in cerebral infarction score of ≥2b) were compared between the specialties after adjusting for treating hospital, patient age, stroke severity, Alberta stroke program early computed tomography score, time from symptom onset to door, and clot location.

Comparison of Smartphone Augmented Reality, Smartglasses Augmented Reality, and 3D CBCT-guided Fluoroscopy Navigation for Percutaneous Needle Insertion: A Phantom Study.

Purpose: To compare needle placement performance using an augmented reality (AR) navigation platform implemented on smartphone or smartglasses devices to that of CBCT-guided fluoroscopy in a phantom.

Materials And Methods: An AR application was developed to display a planned percutaneous needle trajectory on the smartphone (iPhone7) and smartglasses (HoloLens1) devices in real time. Two AR-guided needle placement systems and CBCT-guided fluoroscopy with navigation software (XperGuide, Philips) were compared using an anthropomorphic phantom (CIRS, Norfolk, VA).

Complications and Management of the Thoracic Endovascular Aortic Repair.

Endovascular treatment in thoracic aortic diseases has increased in use exponentially since Dake and colleagues first described the use of a home-made transluminal endovascular graft on 13 patients with descending thoracic aortic aneurysm at Stanford University in the early 1990s. Thoracic endovascular aneurysm repair (TEVAR) was initially developed for therapy in patients deemed unfit for open surgery. Innovations in endograft engineering design and popularization of endovascular techniques have transformed TEVAR to the predominant treatment choice in elective thoracic aortic repair.

Hybrid Repair of Chronic Stanford Type B Aortic Dissection with Expanding Arch Aneurysm.

Purpose: The management of patients with chronic Stanford type B aortic dissection who develop complications requires intervention without clear guidelines. Chronic aortic dissection is difficult to treat and often leads to significant morbidity and mortality. We report a complex case of chronic Stanford type B aortic dissection (TBAD) with an expanding false lumen aneurysm and distal fenestrations that required a multi-stage hybrid repair.
