A Case Of Congenital Coronary Sinus Ostial Atresia With Persistent Left Superior Vena Cava, Laura Onderko, Thomas A. Miller, Sean Novak, Jeffrey Rosenblatt

Journal of Maine Medical Center

Introduction: The coronary sinus is responsible for venous drainage of the heart. Congenital anomalies of the coronary sinus are rare and typically associated with other anomalies, such as atrial septal defects or other congenital heart malformations.

Clinical Findings: We present a case of incidentally found atresia of the coronary sinus ostium with associated persistent left superior vena cava. This case involved a 52-year-old patient who initially presented with a supraventricular tachycardia and elevated troponin.

Clinical Course: The patient underwent cardiac workup with a coronary computed tomographic angiography scan. This scan showed no obstructive coronary artery disease, but did show congenital …

Implementing A Clinical Practice Guideline For Pediatric Appendicitis Safely Reduced Health Care Use And Improved Antimicrobial Stewardship, Jack Vernamonti, Robin Cotter, Jennifer Jubulis, Kartikey Pandya

Journal of Maine Medical Center

Introduction: Appendicitis is the most common emergency surgical disease in children. Those with perforated appendicitis have a more complicated and varied course. Through a clinical practice guideline (CPG), we sought to reduce computed tomography scans, laboratory draws, and exposure to broad-spectrum antibiotics without adversely affecting length of stay, hospital readmission, or repeat antibiotic administration.

Methods: Electronic records were retrospectively reviewed before and after CPG implementation, and data was collected in REDCap.

Results were reported as mean or percent incidence, and statistical analysis was done using a Student’s t-test, Mann-Whitney U test, or Pearson’s χ2 with P < .05 considered significant. Results: One hundred patients with a perforated appendix (50 before and 50 after CPG implementation) were included in our analysis. Length of stay (4.98 vs 4.46 days; P = .25), hospital readmission rate (10% vs 14%; P = .54), and additional antibiotic administration (2% vs 4%; P = .56) did not change. We observed no difference in the Pediatric Appendicitis Score (9 vs 9; P = .48) and a trending increase in evaluation at an outside hospital (56% vs 74%; P = .06). Rates of computed tomography scans did not differ overall (50% vs 40%; P = .31), but showed a decreasing trend at our institution (30% vs 12%; P = .06). We also found fewer post-operative laboratory studies (90% vs 38%; P < .01) and patients who received broad-spectrum intravenous antibiotics (92% vs 18%; P < .01).

Discussion: Through implementing the …

Connected: Using A Novel In-House Communication System To Efficiently Deliver Imaging Results, Daniel Greentree, Brendan R. Calhoun, Steven Farraher

Journal of Maine Medical Center

Introduction: The primary objective was to investigate the effectiveness of a fully staffed electronic communication system (1Connect) in delivering timely critical imaging results and incidental findings. The secondary objective was to evaluate the financial impact of this system on a radiology practice.

Methods: From January 2014 through June 2016, the 1Connect database was retrospectively reviewed and sorted by category of submission type: Critical (1-hour communication time), STAT (2 hours), or Unexpected finding (3 business days). The percent of successful communications completed within the appropriate time frame was calculated for each priority category and used as a measure of the system’s …

Increased 18f-Fdg-Pet Uptake In Granulomatosis With Polyangiitis: Case Report And Review Of The Literature, Rama El-Yafawi, Patricia Cantlin, Thomas E. Van Der Kloot

Journal of Maine Medical Center

We present an unusual case of granulomatosis with polyangiitis (GPA), which initially presented as a large lung mass, without renal or other systemic features. The lung mass was most concerning for malignancy, and positron emission tomography (PET) further supported this concern, with intense uptake in the mass as well as in mediastinal and hilar lymph nodes. Biopsies however were non-diagnostic, and the patient developed acute kidney injury with active urinary sediment, leading to a definitive diagnosis of GPA. With supportive care and treatment directed at GPA, she was ultimately able to discontinue hemodialysis, and the lung mass resolved. This case …
