Endoleaks: Current Concepts And Treatments - A Narrative Review, Zia Ur Rehman

Department of Surgery Docs

Endoleaks are the most common complications following endovascular aneurysm repair. Depending upon their origin, there are five types of endoleaks, types I-V, which can also be classified as direct and indirect endoleaks. Direct endoleaks (type I and III) have higher risk of aneurysm rupture due to rapid sac expansion, and require immediate correction. Indirect endoleaks ( type II, IV and V) have a relatively benign course compared to direct endoleaks. Most of them resolve with time and very few need interventions upon sac enlargement. Type V endotension is a special situation where there is sac enlargement despite no demonstrable endoleak. …

Management Of Pararenal Aortic Aneurysms : A Literature Review, Hilman Ibrahim, Akhmadu Muradi, Ihza Fachriza

The New Ropanasuri Journal of Surgery

Abdominal aortic aneurysms (AAA) are the most common group of aortic aneurysms. Pararenal aortic aneurysm (PAA) is a classification of AAA where there is no normal aortic segment between the renal artery and the proximal border of the aneurysm. This group has a prevalence of around 20% of all AAA cases. In open repair (open surgery), PAA requires suprarenal clamps or even supraceliac which causes high morbidity. In endovascular procedures, PAA presents difficulties due to the absence of a landing zone to place the graft and the possibility of reintervention after action. A literature review is needed to discuss the …

Brachial Artery Aneurysm After Arteriovenous Fistula Ligation Status Post-Kidney Transplant, Alyssa Imperatore, Justin Adibi, Rahul Sharma, Yury Bak

Rowan-Virtua Research Day

Arteriovenous fistulas (AVF) are the most common and effective method of receiving hemodialysis; However, these access techniques do not come without consequence. Aneurysmal degeneration after creation and even years after ligation of such AVF can occur. This is still considered a rare complication. A true brachial artery aneurysm has an overall incidence of 0.17% among peripheral artery aneurysms. Factors that increase incidence of this complication include trauma, age and immunosuppression. Research on this topic is becoming more prevalent, but more answers are still needed. Below is a case of brachial artery aneurysm presenting years after AVF ligation in a patient …

Accuracy Of Procalcitonin Levels For Diagnosis Of Culture-Positive Sepsis In Critically Ill Trauma Patients: A Retrospective Analysis, Aisha Bakhtiar, Syed Jawad Haider Kazmi, Muhammad Sohaib Asghar, Muhammad Nadeem Khurshaidi, Salman Mazhar, Noman A. Khan, Nisar Ahmed, Farah Yasmin, Rabail Yaseen, Maira Hassan

Section of Cardiothoracic Surgery

Background: Abdominal trauma and intra-abdominal sepsis are associated with significant morbidity and mortality. Microcirculation in the gut is disrupted in hemorrhagic and septic shock leading to tissue hypoxia, and the damaged gut acts as a reservoir rich in inflammatory mediators and provides a continual source of inflammation to the systemic circulation leading to sepsis. Sepsis is defined as the presence (probable or documented) of infection together with a systemic inflammatory response to infection. Blood culture is commonly considered to be the preferred approach for diagnosing sepsis, although it is time-consuming, that is, reports are normally available only after 12-48 hours. …

Pulling Heart Strings: Quality Improvement Algorithm For Temporary Epicardial Pacing Wire Removal Post Cardiac Surgery, Jessica Norman

Doctors of Nursing Practice (DNP) Final Projects, 2020-current

The placement of temporary epicardial pacing wires (TEPW) is considered standard practice post cardiac surgery and is dependent on the patient’s cardiac function intra-operatively and their electrophysiologic profile after weaning from cardiopulmonary bypass (Reade, 2007; Elmistekawy et al, 2016). Complications associated with TEPW removal include myocardial damage, infection, perforation, tamponade, disruption of anastomoses, ventricular arrythmias, and death (Bojar, 2009; Carroll et al, 1998;Timothy & Rodeman, 2004). Currently there is no standard practice on the removal of TEPW and there is wide variation in removal practices involving patients who are routinely on medications such as dual antiplatelet therapies and systemic anticoagulation. …

Section of Urology

Technological progress has changed the landscape of surgical practice. Minimally invasive surgery (MIS) and percutaneous interventions (PC) are constantly replacing open procedures. This reduces hospital stay and allows quicker recovery. The application of MIS should follow the good medical practice dictum by Hippocrates i.e. "First do no harm". To remain abreast with new procedures, the medical personnel are required to update and enhance their knowledge and skill. To ensure safety, the innovations are rigorously tested and tried. The learning curve of MIS is shortened by simulator training and proctorship. Credentialing processes are in place to enhance safe delivery of care. …

Rationale And Design Of The Steroids To Reduce Systemic Inflammation After Infant Heart Surgery (Stress) Trial, Kevin D Hill, H Scott Baldwin, David P Bichel, Ryan J Butts, Reid C Chamberlain, Alicia M Ellis, Eric M Graham, Jesse Hickerson, Christoph P Hornik, Jeffrey P Jacobs, Marshall L Jacobs, Robert Db Jaquiss, Prince J Kannankeril, Sean M O'Brien, Rachel Torok, Joseph W Turek, Jennifer S Li, Stress Network Investigators

Faculty, Staff and Students Publications

For decades, physicians have administered corticosteroids in the perioperative period to infants undergoing heart surgery with cardiopulmonary bypass (CPB) to reduce the postoperative systemic inflammatory response to CPB. Some question this practice because steroid efficacy has not been conclusively demonstrated and because some studies indicate that steroids could have harmful effects. STRESS is a randomized, placebo-controlled, double-blind, multicenter trial designed to evaluate safety and efficacy of perioperative steroids in infants (age < 1 year) undergoing heart surgery with CPB. Participants (planned enrollment = 1,200) are randomized 1:1 to methylprednisolone (30 mg/kg) administered into the CPB pump prime versus placebo. The trial is nested within the existing infrastructure of the Society of Thoracic Surgeons Congenital Heart Surgery Database. The primary outcome is a global rank score of mortality, major morbidities, and hospital length of stay with components ranked commensurate with their clinical severity. Secondary outcomes include several measures of major postoperative morbidity, postoperative hospital length of stay, and steroid-related safety outcomes including prevalence of hyperglycemia and postoperative infectious complications. STRESS will be one of the largest trials ever conducted in children with heart disease and will answer a decades-old question related to safety and efficacy of perioperative steroids in infants undergoing heart surgery with CPB. The pragmatic "trial within a registry" design may provide a mechanism for conducting low-cost, high-efficiency trials in a heretofore-understudied patient population.

Evaluation Of The Role Of Microvascular Pathology On Peripheral Artery Disease, Constance Mietus

Theses & Dissertations

Background: Peripheral Artery Disease (PAD) begins with atherosclerotic narrowing of arteries, including those that supply the legs. Individuals with PAD experience pain during walking, which becomes increasingly limiting. Studies from our group and others have shown that a myopathy is present in the skeletal muscle of PAD patients, and is characterized by myofiber degeneration, fibrosis, and remodeling of vessels ranging from 50 – 150 mm in diameter. However, microvascular pathology, particularly of the smallest microvessels (5 – 15 mm in diameter) remains poorly characterized. Furthermore, little is known about the relationships between microvascular architecture, microperfusion, and patient walking performance. We …
