Abstract(Please copy/paste the abstract send to the congress) : EFFICACY OF ICE COLLAR IN HEAD AND NECK BLEEDING CONTROL
PURPOSE:
To assess the impact of ice collar on the blood flow (BF) of the internal (ICA) and external carotid (ECA), facial (FA) and temporalis (TA) arteries.

MATERIALS AND METHODS: 
The Study consists of three separate phases conducted on 10 men and 2 women (mean age of 29.8±3 yrs) (1) Cervical and tympanic temperatures, systolic (SBP), diastolic blood pressure (DBP) and heart rate (HR) were measured at the baseline and every 5 minutes for 25 minutes once with ice collar (-6°C) in place and then after it was removed. (2) Blood flow of ICA, ECA, FA and TA were assessed before applying regular collar (25°C), promptly after removing it and 10 minutes after collar removal using Doppler US. Facial and temporal BF was measured 5 and 15 minutes after applying regular collar as well. (3) Second phase was repeated this time using an ice collar. 

RESULTS:
Applying ice collar was significantly associated with tympanic and cervical temperatures (P=0.002 and <0.0001, respectively) while it had no significant impact on the HR (P=0.1), SBP (P=0.5) and DBP (P=0.3). Applying regular collar did not significantly affect BF of the internal and external carotid, facial and temporalis arteries (P=0.9, 0.1, 0.5 and 0.06 respectively). Pearson's correlation coefficients for flow assessment of ICA, ECA, FA and TA by Doppler US before collar use and after collar removal were 0.73, 0.96, 0.76 and 0.90 respectively (P= 0.01, <0.001, 0.02, <0.0001 respectively). Ice collar use did not alter BF to ICA (P=0.1) but significantly decreased BF to ECA, FA and TA (P=0.0002, <0.0001 and <0.0001; respectively)

CONCLUSION:
Obtained test-retest-reliability coefficient indicated that Doppler US is a reliable method for BF assessment of the ICA, ECA, facial and temporalis arteries. Cold application on neck can decrease the BF of the ECA, FA and TA while BF to ICA remains unchanged. This method can potentially be used to control ECA bleeding without compromising brain’s blood supply. 

CLINICAL RELEVANCE:
We proved the positive impact of ice collar on decreasing BF to cervical arteries, which can serve as an effective, non-invasive method to control the head and neck bleeding.

Your experiences about the travel processes(Providing ticket, accommodation,...) :  
Please give a briefing of your own observations and outcomes of the congress: : I participated in scientific and educational refreshment courses.It was a great opportunity to maximize my learning and be familiar with advanced and novel imaging techniques.I also participated in RSNA case of the day and RSNA Diagnosis Live everyday and won ribbon for my correct answers.I presented my manuscript orally successfully and achieved some beneficial comments regarding my research project which will help me to go further with my research as well.I had an opportunity to visit exibitional part of the congress and learn post processing of novel imaging techniques such as perfusion CT Scan.I attended Essential imaging of neuroradiology and head and neck, cardiac, Muskuloskeletal,Chest, Gastrointestinal, interventional radiology and these courses were really effective for updating me as a faculty at Tehran University of Medical Sciences.
