    Abstract Mycotic aortic aneurysms are a rare and potentially fatal aortic pathology. Advancements in vascular technology have allowed endovascular repair to be a durable and less invasive option for the treatment of mycotic aortic aneurysms. We have presented the case of a 51-year-old man with a mycotic aneurysm of the descending thoracic aorta secondary to chronic, disseminated aspergillosis infection after liver transplantation. The aneurysm was successfully treated with thoracic aortic stent graft deployment. No perioperative complications occurred, and follow-up computed tomography angiography showed no signs of an endoleak. The patient will continue with lifelong antifungal therapy and close follow-up with vascular surgery.

    Abstract Background and objectives: Tramadol is commonly prescribed to manage chronic pain in older patients. However, there is a gap in the literature describing the pharmacokinetic parameters for tramadol and its active metabolite (O-desmethyltramadol [ODT]) in this population. The objective of this study was to develop and evaluate a population pharmacokinetic model for tramadol and ODT in older patients.
    Methods: Twenty-one patients who received an extended-release oral tramadol dose (25-100 mg) were recruited. Tramadol and ODT concentrations were determined using a validated liquid chromatography/tandem mass spectrometry method. A population pharmacokinetic model was developed using non-linear mixed-effects modelling. The performance of the model was assessed by visual predictive check.
    Results: A two-compartment, first-order absorption model with linear elimination best described the tramadol concentration data. The absorption rate constant was 2.96/h (between-subject variability [BSV] 37.8%), apparent volume of distribution for the central compartment (V
    Conclusion: Exposure to tramadol increased with increased frailty and reduced CrCL. Prescribers should consider patients frailty status and CrCL to minimise the risk of tramadol toxicity in such cohort of patients.

    Abstract Background: Minimally invasive approaches to the spine via anterior and posterior approaches have been increasing in popularity, culminating in the development of robot-assisted spinal fusions. The da Vinci surgical robot has been used for anterior lumbar interbody fusion (ALIF), with promising results. Similarly, multiple spinal robots have been developed to assist placement of posterior pedicle screws. However, no previous cases have reported on using robots for both anterior and posterior fixation in a single surgery. We present a technical note on the first reported case of a totally robotic minimally invasive anterior and posterior lumbar fusion and instrumentation.
    Methods: A 65-year-old man with chronic low back pain and left greater than right lower extremity radiculopathy was found to have grade 1 spondylolisthesis at L5/S1 that worsened on standing upright. He underwent ALIF using a da Vinci robotic approach, followed by percutaneous posterior instrumented fusion with the Globus Excelsius GPS robot.
    Results: The patient did well postoperatively, with improvement of back and leg pain at 3 months follow-up. Radiography confirmed appropriate placement of the interbody cage and pedicle screws.
    Conclusions: All-robotic placement of both ALIF and posterior lumbar pedicle fixation may be safe, feasible, and efficacious.

    Abstract A substantial number of patients may experience a systemic inflammatory response syndrome (SIRS) and related adverse events after transcatheter aortic valve implantation and endovascular aortic aneurysm repair. Although a clear etiology has not been established, endothelial disruption and tissue-ischemic response secondary to the foreign material may represent the trigger events. A latency period (0-48 hours) may occur between the initial injury and onset of symptoms mirroring an initial local response followed by a systemic response. Clinical presentation can be mild or severe depending on external triggers and patient's characteristics. Diagnosis is challenging because it simulates an infection, but lack of response to antibiotics, negative cultures are supportive of SIRS. Increased in-hospital stay, readmissions, major cardiovascular events, and reduced durability of the device used are the main complications. Treatment includes non-steroidal anti-inflammatory drugs or corticosteroids. In conclusion, further studies are warranted to fully explore pathophysiologic mechanisms underpinning SIRS as well as the possibility to enhance device material immune compatibility in order to reduce the host tissue's inflammatory reaction.

    Abstract Objective: Aortic aneurysms and dissections are prevalent causes of morbidity and mortality. The management of aortic pathologies may be called into question in malpractice suits. Malpractice claims were analyzed to understand common reasons for litigation, medical specialties involved, patient injuries, and outcomes.
    Methods: Litigation cases in the Westlaw database from September 1st, 1987 to October 23 rd, 2019 were analyzed. Search terms included "aortic aneurysm" and "aortic dissection." Data on plaintiff, defendant, litigation claims, patient injuries, misdiagnoses, and case outcomes were collected and compared for aortic aneurysms, aortic dissections, and overall cases.
    Results: A total of 346 cases were identified, 196 involving aortic aneurysms and 150 aortic dissections. Physician defendants were emergency medicine (29%), cardiology (20%), internal medicine (14%), radiology (11%), cardiothoracic (10%) and vascular surgery (10%). Litigation claims included "failure to diagnose and treat" (61%), "delayed diagnosis and treatment" (21%), "post-operative complications after open repair" (10%) and "negligent post-operative care" (10%). Patients with aneurysms presented with abdominal (63%) and back pain (37%), while dissections presented with chest pain (78%), abdominal pain (15%), and shortness of breath (14%). Misdiagnoses included gastrointestinal (12%), other cardiovascular (9%), and musculoskeletal conditions (9%), but many were not specified (58%). Overall, 83% of cases were wrongful death suits. Injuries included loss of consortium (23%), emotional distress (19%), and bleeding (17%). In 53% of the cases, the jury ruled in favor of the defendant. 25% of cases ruled for the plaintiff. 22% of cases resulted in a settlement. The mean rewarded for each case was $1,644,590.66 (SD: $5,939,134.58; Range: $17,500-$68,035,462).
    Conclusion: For aortic pathologies, post-operative complications were not prominent among the reasons why suits were brought forth. This suggests improvements in education across all involved medical specialties may allow for improved diagnostic accuracy and efficient treatment, which could then translate to a decrease in associated litigation cases.

    Abstract The collapse of an abdominal aortic endograft is a rare event. We present the case of a 60-year-old man with an abdominal endograft who came to the emergency department with chest, back, abdominal, and lower extremity pain in addition to a cool left foot. On imaging, he was found to have a type B aortic dissection and a collapsed abdominal endograft. Subsequently, the patient was taken to the operating room and treated with a thoracic endovascular aortic repair, abdominal aortic cuff, and an iliac stent. Our study details this case and thoroughly reviews similar cases in the literature.

    Abstract Objective: It is unclear whether patients with prior neck radiation therapy (RT) are at high risk for carotid artery stenting (CAS). We aimed to delineate 30-day perioperative and 3-year long-term outcomes in patients treated for radiation-induced stenotic lesions by the transfemoral carotid artery stenting (TFCAS) or transcarotid artery revascularization (TCAR) approach to determine comparative risk and to ascertain the optimal intervention in this cohort.
    Methods: Data were extracted from the Vascular Quality Initiative CAS registry for patients with prior neck radiation who had undergone either TCAR or TFCAS. The Student t-test and the χ
    Results: A total of 72,656 patients (TCAR, 40,879; TFCAS, 31,777) were included in the analysis. Of these, 4151 patients had a history of neck radiation. Patients with a history of neck radiation were more likely to be younger, white, and have fewer comorbidities than patients with no neck radiation history. After adjustment for confounding factors, there was no difference in relative risk of 30-day perioperative stroke (P = .11), death (P = .36), or myocardial infarction (MI) (P = .61) between TCAR patients with or without a history of neck radiation. The odds of stroke/death (P = .10) and stroke/death/MI (P = .07) were also not statistically significant. In patients with prior neck radiation, TCAR had lower odds for in-hospital stroke/death/MI (odds ratio, 0.59; 95% confidence interval [CI], 0.35-0.99; P = .05) and access site complications than TFCAS. At year 3, patients with prior neck radiation had an increased hazard for mortality after TCAR (hazard ratio [HR], 1.24; 95% CI, 1.02-1.51; P = .04) and TFCAS (HR, 1.33; 95% CI, 1.12-1.58; P = .001). Patients with prior neck radiation also experienced an increased hazard for reintervention after TCAR (HR, 2.16; 95% CI, 1.45-3.20; P < .001) and TFCAS (HR, 1.67; 95% CI, 1.02-2.73; P<.001).
    Conclusions: Patients with prior neck radiation had a similar relative risk of 30-day perioperative adverse events as patients with no neck radiation after adjustment for baseline demographics and disease characteristics. In these patients, TCAR was associated with reduced odds of perioperative stroke/death/MI as compared with TFCAS. However, patients with prior neck radiation were at increased risk for 3-year mortality and reintervention.

    Abstract Introduction: Thoracic endovascular aortic repair (TEVAR) has become first-line therapy for a wide range of thoracic aortic pathologies including traumatic thoracic aortic injury, type B aortic dissection, intramural thoracic aortic hematoma, and penetrating aortic ulcers. This study aims to analyze the progress made of thoracic stent graft devices, review the current Food and Drug Administration (FDA)-approved devices, and discuss the future technological advances.
    Materials and methods: In this paper, we will review the history of TEVAR and the development of the first iteration of devices. We will discuss the four currently available TEVAR devices, the GORE® TAG® (W. L. Gore and Associates, Flagstaff, Arizona), Medtronic Navion™ (Medtronic plc, Santa Rosa, California), Bolton RELAY® (Terumo Aortic, Sunrise, Florida), and the Zenith® Alpha™ Thoracic and the Zenith® Dissection Stent Graft (Cook Medical, Bloomington, Indiana), and the features and applications of each. Finally, future advancements in TEVAR technology and grafts currently under trial will be reviewed.
    Results: The first generation of TEVAR grafts had several limitations including large delivery systems, the need for rapid pacing for accurate deployment, wind socking during deployment, and graft migration. The current available TEVAR grafts have novel features to address these prior pitfalls. The GORE® TAG® is initially deployed 50% with subsequent room for adjustment to increase accuracy; the Medtronic Navion™ and Bolton RELAY® are available in low-profile delivery systems; and the Cook Zenith® Alpha™ now has an open cell petticoat specific for use in dissections extending to the visceral abdominal aorta. The current generation of TEVAR devices have broadened the application of TEVAR and reduced the anatomic limitations previously encountered.
    Conclusion: TEVAR has evolved to overcome technical challenges and offer expanded applicability to different types of thoracic aortic pathologies and enhanced accuracy of deployment.
