Pancreatitis is one of most complex and clinically challenging of all abdominal disorders. USG and abdominal Computed Tomography (CT) are the most commonly used diagnostic imaging modalities for the evaluation of pancreas. Computed Tomography (CT) is highly accurate and sensitive than USG in both diagnosing as well as demonstrating the extent. Early assessment of the cause and severity of acute pancreatitis is of utmost importance for prompt treatment and close monitoring of patient with severe disease. CT is the imaging method of choice for assessing the extent of acute pancreatitis and for evaluating complications. CT severity index is used to assess prognostic correlation and clinical outcome of acute pancreatitis. Modified CT severity index makes the score easier to calculate and reduces the inter-observer variation. KYAMC Journal Vol. 10, No.-2, July 2019, Page 110-113

Background and Purpose: Acute onset aphasia may be due to stroke but also to other causes, which are commonly referred to as stroke mimics. We hypothesized that, in patients with acute isolated aphasia, distinct brain perfusion patterns are related to the cause and the clinical outcome. Herein, we analyzed the prognostic yield and the diagnostic usefulness of computed tomography perfusion (CTP) in patients with acute isolated aphasia. Methods: From a single-center registry, we selected a cohort of 154 patients presenting with acute isolated aphasia who had a whole-brain CTP study available. We collected the main clinical and radiological data. We categorized brain perfusion studies on CTP into vascular and nonvascular perfusion patterns and the cause of aphasia as ischemic stroke, transient ischemic attack, stroke mimic, and undetermined cause. The primary clinical outcome was the persistence of aphasia at discharge. We analyzed the sensitivity, specificity, positive and negative predictive values of perfusion patterns to predict complete clinical recovery and ischemic stroke on follow-up imaging. Results: The cause of aphasia was an ischemic stroke in 58 patients (38%), transient ischemic attack in 3 (2%), stroke mimic in 68 (44%), and undetermined in 25 (16%). CTP showed vascular and nonvascular perfusion pattern in 62 (40%) and 92 (60%) patients, respectively. Overall, complete recovery occurred in 116 patients (75%). A nonvascular perfusion pattern predicted complete recovery (sensitivity 75.9%, specificity 89.5%, positive predictive value 95.7%, and negative predictive value 54.8%), and a vascular perfusion pattern was highly predictive of ischemic stroke (sensitivity 94.8%, specificity 92.7%, positive predictive value 88.7%, and negative predictive value 96.7%). The 3 patients with ischemic stroke without a vascular perfusion pattern fully recovered at discharge. Conclusions: CTP has prognostic value in the workup of patients with acute isolated aphasia. A nonvascular pattern is associated with higher odds of full recovery and may prompt the search for alternative causes of the symptoms.

Background: Extracorporeal cardiopulmonary resuscitation (ECPR) is a promising treatment for refractory cardiac arrest. Computed tomography (CT) is often performed after ECPR for diagnosis of etiology and evaluation of complications. However, few studies have reported left ventricular wall findings in contrast-enhanced CT (CE-CT) after ECPR. This study examined the left ventricular wall CE-CT findings after ECPR, and evaluated the association between these findings and the results of coronary angiography and prognosis. Method: We evaluated out-of-hospital cardiac arrest patients who were treated with ECPR and then underwent both non-ECG gated CE-CT and coronary angiography at our center between January 2011 and April 2018. The left ventricular wall CE-CT findings at 90 s after contrast injection were classified as follows: homogeneously-enhanced (HE), left ventricular wall was homogeneously enhanced; segmental defect (SD), left ventricular wall was not segmentally enhanced according to coronary artery territory; total defect (TD), entire left ventricular wall was not enhanced; and others. Significant stenosis on coronary angiography, survival to hospital discharge, and successful weaning from extracorporeal membrane oxygenation (ECMO) were examined. Results: A total of 111 patients were eligible. Median age was 59 years, and 85 (77%) had initial shockable rhythm. A total of 37 (33%) survived to hospital discharge. HE was observed in 33 patients, SD in 41, TD in 15, and others in 22. Among 74 patients who underwent CT prior to coronary angiography, SD predicted significant stenosis, with sensitivity of 83% and specificity of 100%. Among all patients, 28 (85%) with HE, 15 (37%) with SD, and 3 (20%) with TD were weaned successfully from ECMO. In addition, 17 (52%) patients with HE, 10 (24%) with SD, and 2 (13%) with TD survived to hospital discharge. Conclusion: SD could predict coronary artery stenosis with good specificity. Patients with HE had higher success rates for weaning from ECMO. On the other hand, TD was associated with poor outcomes. The left ventricular wall findings in non-ECG gated CE-CT after ECPR might be useful in diagnosis and prognostication.

Hospital Cardiac Arrest

Introduction: Head computed tomography (HCT) is often performed to assess for hypoxic-ischemic brain injury in resuscitated out of hospital cardiac arrest (OHCA) patients. Our primary objective was to assess whether cerebral edema (CE) on early HCT is associated with poor survival and neurologic outcome post OHCA. Methods: We included subjects from a prospectively collected cardiac arrest database of OHCA adult patients who received targeted temperature management (TTM) at two academic suburban hospitals from 2009-Sept-2018. Cases were included if a HCT was performed in the emergency department (ED). Patient demographics and cardiac arrest variables were collected. HCT results were abstracted by study authors from radiology reports. HCT findings were categorized as no acute disease, evidence of CE, or excluded (bleed, tumor, stroke). Outcomes were survival to discharge or cerebral performance scores (CPC) at discharge of three or four (poor neurologic outcome). Descriptive statistics, univariate, multivariate, survival, and interrater reliability analysis were performed. Results: During the study period, there were 425 OHCA, 277 cases had ED HCTs performed; 254 cases were included in the final survival analysis. Patients were predominately male, 189 (65.0%), average age 60.9 years, average BMI of 30.5. Of all cases, 44 (15.9%) showed CE on CT. Univariate analysis demonstrated that CE was associated with 9.2-fold greater odds of poor outcome (OR: 9.23; 95% CI 1.73, 49.2), and 9.1-fold greater odds of death (OR: 9.09: 95% CI 2.4 33.9). In adjusted analysis, CE was associated with 14.9-fold greater odds of poor CPC outcome (AOR: 14.9, 95% CI, 2.49, 88.4), and 13.7-fold greater odds of death (AOR: 13.7, 95% CI, 3.26, 57.4). Adjusted survival analysis demonstrated that patients with CE on HCT had 3.6-fold greater hazard of death than those without CE (HR: 3.56: 95% CI 2.34, 5.41). Interrater reliability demonstrated excellent agreement between reviewers for CE on HCT (κ = 0.86). Conclusion: The results identify that abnormal HCTs early in the post-arrest period in OHCA patients are associated with poor rates of survival and neurologic outcome. Prospective work is needed to confirm whether selection bias or other variables confound this association.
