ABSTRACT
Background: CT-pulmonary angiography [CTPA] is routinely performed in patients with suspected pulmonary embolism [PE] and a positive relationship between Qanadli score [Q-score] and RVdysfunction enables the clinicians in early diagnosis and management of RV-dysfunction on the basis of this single imaging modality. Objective of the study was to determine the correlation between an established angiographic clot burden score [Qanadli score-QS] and parameters of right ventricular dysfunction [RVD] on CT pulmonary angiography in patients with acute pulmonary embolism
Methods: A Cross-sectional study was carried out for the period of six months from 16 Jun to 15 Dec 2016. Total of forty-six [46] patients of either gender aged 15-70 years with confirmed evidence of PE were recruited. The Q-score and parameters of RV-dysfunction [LV/RV, ratio, SVC diameter, AVdiameter and PA/Ao ratio] were calculated in each patient. Correlation between Q-Score and RV parameters were determined and binary logistic regression analysis was applied to assess Q-score as an independent predictor of RV-dysfunction
Results: Avery strong positive correlation was found between Q-score and LV/RV ratio [r>0.7, p<0.05] collectively and after gender and age based stratification. No significant correlation was found between Q-score and other RV parameters among both genders and age groups [p>0.05 in all cases]. No independent factors were found to be significantly related to RV dysfunction after adjustment for other factors [p>0.05]
Conclusion: Qanadli score on CT pulmonary angiogram correlates positively with indicators of right ventricular dysfunction of CT angiogram in patients with acute pulmonary embolism and confer a poor prognosis with higher scores
ABSTRACT
Urinary lithiases have been a major urological problem. The objective was to determine the out come of treatment for patients with calculus anuria. A descriptive study was conducted at Department of Urology Chandka Medical College Hospital, Larkana from March 2007 to April 2009. All patients with a diagnosis of calculus anuria of all ages and either sex were included in the study. Detailed history, physical examination and examination of genitourinary tract was performed. Investigations included complete blood examination, blood urea, serum creatinine, ultrasonography of KUB area, and X-Ray KUB. Among the 66 patients the cause of anuria was bilateral obstruction by the calculi in 46 cases, unilateral obstruction with small/absent/nephrectomised contralateral kidney in 20 cases. In most of the cases, ureteric catheterisation was done to relieve the obstruction. Five deaths were observed, despite emergency urinary diversion and appropriate treatment. Calculus anuria is a urological emergency. Prompt and early intervention can save the life of patient and prevent to develop chronic renal failure
