- چکیده انگلیسی: Introduction:
Arteriovenous malformations (AVMs) are uncommon vascular lesions that can arise in any part of
the body.
Case Report:
In this case study, we presented a huge AVM of the upper lip in a 70-year-old man that he noticed since 5years ago with slow growth in this period. Computed tomography angiography revealed a large AVM with feeders from the right facial artery and its branch superior labial artery. Right facial artery showed increased diameter and tortuous changes. Selective catheterization of right carotid was performed followed by super selective catheterization of the right facial artery. Then, the embolization of the tumor blush was conducted. Surgical removal of the tumor was carried out10days after the embolization.
Conclusion:
The AVM treatment is challenging, and there is a high chance of recurrence and progression. Every case should have an individualized approach that needs an accurate diagnosis and a multidisciplinary team.- انتشار مقاله: 04-10-1397

- چکیده انگلیسی: Background
Currently, almost all patients with probable abdominal injury undergo urinalysis in emergency department (ED). The present survey was conducted with the aim of assessing the diagnostic values of urinalysis compare with abdominal computed tomography (CT) scan with contrast for predicting possible intra-abdominal injuries in children affected by blunt trauma.
Materials and Methods: The present diagnostic accuracy study was accomplished on patients' < 16-year-old with blunt abdominal trauma who were admitted to emergency department (ED) and underwent both urinalysis and abdominal CT scan. Demographic and baseline characteristics data, and the results of urinalysis and abdominal CT scan were recorded. Thereafter, screening performance characteristics were calculated.
Results
Seventy eligible patients with the mean age of 7.1 ± 4.86 years were enrolled (68.6% male). Screening performance characteristics including sensitivity, specificity and positive and negative predictive values of hematuria were 26.7%, 92.7%, 50.0% and 82.3%, respectively. Positive and negative likelihood ratios were calculated as 3.67 and 0.79, respectively.
Conclusion
It is likely that, presence of hematuria has acceptable specificity, but very low sensitivity in comparison with CT scan for prediction of abdominal organ injuries in children with blunt abdominal trauma. Therefore, urinalysis is not useful for screening the presence of organ injuries in this population.- انتشار مقاله: 14-06-1396

- چکیده:
- چکیده انگلیسی: Objective: To evaluate the diagnostic value of DWI in assessment of metastatic neck lymph node in a sample of
Iranian patients with Head and Neck cancer. Methods: 25 patients with 80 neck lymph nodes were analyzed using 1.5 T
MRI. DWI was performed with b values of 0 and 1,000 s/mm2. Short axis diameter and ADC values (min, max and mean)
were calculated for metastatic and non-metastatic neck LNs and results were compared with histopathological findings.
The optimal ADC thresholds were analyzed using receiver coefficient characteristic (ROC) curves for discriminating
between metastatic and benign neck lymph nodes. Result: Histopathological findings revealed that there are 45% (n=36)
metastatic and 55% (n=44) non-metastatic neck LNs respectively. There was no statistically significant difference in
short axis diameter between the two groups (p = 0.346). However, The ADC values of metastatic neck LNs were
significantly lower than those of non-metastatic neck LNs (p < 0.001); 0.90 ± 0.10 × 10-3 mm2/s vs 1.06 ± 0.12 × 10-3
mm2/s ( ADC mean ), 0.78 ± 0.08 × 10-3 mm2/s vs 0.92 ± 0.20× 10-3 mm2/s ( ADC min ) and 1.02 ± 0.12 × 10-3 mm2/s
vs 1.24 ± 0.15 × 10-3 mm2/s (ADC max ). The optimal mean ADC threshold value was equal to 0.996 × 10-3 mm2/s
for differentiating malignant from benign lymph nodes with sensitivity, specificity and accuracy of 80.56 %, 77.27 %
and 71.59 % respectively. Conclusion: MR diffusion imaging and ADC values as a non-invasive technique can assess
metastatic neck LNs in head and neck cancer with higher sensitivity, specificity and accuracy.- انتشار مقاله: 10-09-1397
