RESUMO
Background: Percutaneous endoscopic gastrostomy (PEG) procedures are performed under sedation in critically ill patients who cannot be fed orally. Aim: We compared the efficacy and safety of propofol-fentanyl and propofol-ketamine for deep sedation in patients undergoing PEG. Retrospective Study. Materials and Methods: The study was conducted from 1 January 2013 to 31 December 2018 in Adiyaman University. The patients given propofol-fentanyl (0.5-1.2 mg/kg and 0.2-1 µg/kg, respectively) for sedo-analgesia were designated Group F, and those who received propofol-ketamine (0.2-0.6 mg/kg and 0.5-1 mg/kg, respectively) were placed in Group K. The demographic and hemodynamic characteristics, recovery times, perioperative complications, and need for additional doses were recorded. Results: Seventy-one patients who underwent PEG were analyzed. The age, sex, American Society of Anesthesiologists (ASA) score, comorbidities, duration of anesthesia, and duration of the PEG procedure were similar in the two groups. Recovery time was longer in Group K. The total propofol dose was 64 mg in Group F and 35 mg in Group K. Additional doses of propofol were administered to 12 patients in Group F, compared to none in Group K. The mean blood pressure values were higher in Group K at all-time points. The perioperative complication rate was higher in Group F. Desaturation was observed in 9 (22.5%) patients in Group F and in 3 (9.6%) patients in Group K. Hypotension was observed in 4 (10%) patients in Group F. Conclusion: Propofol-ketamine should be preferred for sedoanalgesia during PEG procedures because of the lower dose of propofol, more stable blood pressure, and greater peripheral oxygen saturation. In addition, we believe ketamine-propofol is safer based on its low complication rate.

The ectopic origination of a coronary artery from the opposite sinus is a rare condition, often discovered as an incidental finding during invasive catheter angiography performed for the evaluation of atherosclerotic coronary artery disease. Although most patients lack hemodynamic significance, a small fraction of these anomalies have been associated with sudden cardiac death and ischemic complications. The exact anatomic definition of the anomalous coronary artery and its course, especially in relation to the ascending aorta and the pulmonary trunk, is therefore crucial for every imaging modality that attempts coronary artery visualization. To underline the potential of 3-dimensional electron-beam computed tomography as an important complement to invasive angiography in the delineation of anomalous coronary arteries, this study focused on the potentially malignant ectopic contralateral origination of a coronary artery.

Ebstein's anomaly (EA) is primarily diagnosed by echocardiography. The purpose of this study was to compare echocardiography and magnetic resonance imaging (MRI) in EA. Data from cardiac MRI and echocardiography were prospectively collected from 16 patients with EA. Imaging data also were compared with intraoperative findings. Information provided by MRI and echocardiography were comparable for left ventricular size and function, tricuspid valve repairability, qualitative assessment of right-sided cavities, and visibility of septal and anterior tricuspid valve leaflets. The posterior tricuspid valve leaflet and tricuspid valve fenestrations were better visualized with MRI; associated heart defects were equally recognized, apart from small shunts that tended to be more readily diagnosed with echocardiography. Quantification of right-cavity size and right ventricular ejection fraction was possible only with cardiac MRI. The degree of tricuspid valve regurgitation was underestimated by echocardiography (2 patients) and by MRI (4 patients) when compared with intraoperative assessment. When evaluating EA, echocardiography and MRI provide complementary data. For visualization of the posterior tricuspid valve leaflet and quantitative assessment of right ventricular size and function, MRI is preferable. For appropriate risk stratification in EA, both MRI and echocardiography should be performed before cardiac surgery.

The objective of this study was to compare the anatomic course of anomalous coronary arteries by axial and three-dimensional volume-rendered electron beam computed tomography (EBCT) angiography and X-ray catheter angiography (CAG). We performed a blinded study where patients who previously underwent CAG with (n = 14) and without (n = 14; age- and gender-matched controls) anomalous coronary anatomy were studied with EBCT coronary angiography. Forty to 50 EKG-triggered 3 mm overlapping axial slices were acquired with 2 mm table movement within one breath hold during the i.v. injection of 140 cc of nonionic iodinated contrast (4 ml/sec). The axial source images and volume-rendered three-dimensional reconstructions were evaluated for the presence, type, and course of coronary anomalies and the results were compared to those of CAG. All normal and anomalous coronary arteries were identified by both modalities in all subjects. Identified anomalies include single coronary artery (n = 3), left-sided right coronary artery (n = 3), right-sided left main coronary artery (n = 3), anterior descending coronary artery (n = 2), circumflex coronary artery (n = 2), and separate left-sided ostia for left anterior descending and circumflex coronary arteries (n = 1). In five cases, there was discrepancy in the course of the anomalous vessels between the two modalities. Consensus reading among cardiologist and radiologists favored the interpretation of EBCT over catheter angiography. Noninvasive EBCT coronary angiography compares well with CAG in identifying anomalous coronary arteries and may provide confirmatory evaluation of their precise anatomic relationships to the heart and great vessels.
