Roux-en-y gastric bypass (RYGB) is one of the most common weight loss surgical procedures performed in the United States. Early post-operative small bowel obstruction is a rare but potentially morbid, complication of RYGB. We report two patients who underwent RYGB and required subsequent treatment for a post-operative small bowel obstruction. Their post-operative course was complicated by severe aspiration pneumonitis leading to hypoxemic respiratory failure requiring rescue with femoral veno-venous extracorporeal membrane oxygenation (V-V ECMO). Both patients were successfully extubated, weaned off V-V ECMO support, and discharged to home. These cases highlight the potential role of V-V ECMO for patients who …

Faculty, Staff and Students Publications

Anti-synthetase syndrome (AS) is a rare autoimmune disorder characterized by the presence of aminoacyl-transfer RNA synthetase antibodies in conjunction with clinical features such as interstitial lung disease (ILD), Raynaud's phenomenon, nonerosive arthritis, and myopathy. AS distinguishes itself from other inflammatory myopathies by its significant lung involvement and rapidly progressive interstitial lung disease (AS-ILD), therefore the management of AS-ILD requires careful clinical, serologic and radiologic assessment. Glucocorticoids are considered the mainstay of therapy; however, additional immunosuppressive agents are often required to achieve disease control. Patient prognosis is highly dependent on early diagnosis and symptom recognition as the antibody profile is thought …

Superoxide And Pulmonary Hypertension, Tammy Wichman Aug 2021

Superoxide And Pulmonary Hypertension, Tammy Wichman

Theses & Dissertations

Pulmonary arterial hypertension (PAH) is a devastating cardiovascular disease, which is progressive and fatal despite advances in therapy. Animal models have shown that oxidative stress may be pathogenic in PAH. We hypothesize that oxidative stress, as measured by increased levels of a specific reactive oxygen species, superoxide (O2•-), mayplay a role in PAH in humans. Using a novel application of electron paramagnetic resonance (EPR) spectroscopy, we initially evaluated whether levels of O2•- from whole blood collected from the pulmonary artery collected during right heart catheterization (RHC) would correlate with O2•- levels in peripheral …
