  ABSTRACT

  Background and Aim: In most individuals, each kidney is supplied by a single renal^�artery and a vein, however multiple renal arteries and veins is not uncommon. In comparison to conventional angiography computed tomographic (CT)^�angiography is a new and less aggressive measure used for detection of normal renal vascular anatomy and diagnosis^�of vascular variants. To evaluate the frequency of normal vascular variants in 62 patients (124 Kidneys), underwent abdominal CT Angiography (Aortography).

  Material and Methods: During a period of one year, abdominal CT angiography was performed in 62 patients, 48 male and 14 female between 7-74 years of age (Mean 25.68 years). The angiographic images were studied after being reconstituted by use of a computer. There was no complication and all patients tolerated the procedure without any reaction and/or discomfort. One forth of the patients felt some warmness during contrast injection.

  Results: In 98 (79%) kidneys only one renal artery, in 20 kidneys (16.1%) two arteries, in 4 kidneys three arteries, and in two kidneys four arteries were detected. In 109 kidneys (88%) only one vein and in 15 kidneys (12%) two renal veins were detected and circum-aortic renal vein or renal collar was found only in one case.

  Conclusion: In this study the frequency of multiple renal vascular variants was less common than those of other studies. By use of spiral CT angiography and reconstitution of images by a computer, renal arteries and veins can be investigated in a short time avoiding invasive sequela or any complication for the patients.

Background and Aim: Pulmonary thromboembolism is an important clinical problem in the patients after major surgeries and is often difficult to diagnose because of nonspecific clinical symptoms. Diagnosis of pulmonary embolism is based on medical imaging methods. The aim of this study was to evaluate the results of CT pulmonary angiographies of the patients with primary clinical diagnosis of pulmonary thromboembolism in Besat Hospital between 2014 and 2015.
Materials and Methods: This cross-sectional study included 160 patients with primary diagnosis of pulmonary embolism who had been referring to Besat Hospital from 2014 to 2015. Data were extracted from the patient’s `medical records and we used in a checklist for every patient for data collection. Using SPSS software, data were analyzed by descriptive statistics such as mean, median, standard deviation and ratio. Chi-square and t-test were used to find out the relationship between the variables.
Result: The results of this study showed that 56.3% of the subjects were female. The mean age of the participants was 45.49 ± 18.5 years, 25.65% were between 31 and 40 years of age and 29.4% had abnormal CT scan results indicative of a definite cause for pulmonary embolism. There was a statistically significant relationship between abnormal CT scan and the results of di-dimer test (p = 0.001). There was also a statistically significant relationship between gender and abnormal CT scan results, so that most patients with abnormal CT scan were male (p = 0.002). Mean age, blood pressure, di-dimer test, respiratory rate, and heart rate were higher in subjects with abnormal CT scan.
Conclusion: According to the findings of this study, male patients between 31 and 40 years of age with abnormal CT scans should be examined more closely in order to reduce the mortality rate of the patients.
