Abstract
"Arterial Thromboembolism" is the most common cause of "Acute Arterial Ischemia" of extremities. In this study, It is attempted to collect retrospectively some documentary information of all "acute arterial thromboembolic occlusions of the limbs".
Materials and Methods: In descriptive retrograde study in Sina General hospital, all related records in this regard were collected from March 1991 to March 1997. To reveal the statistical outcomes and analysis the associations between them as well, the statistical tests like nonparametric ones were employed.
Results: Total number of the cases was 24 with " Acute Thromboembolic Arterial limb Ischemia" (3 in upper and 21 in lower limbs). The results were as follows: Female to male ratio =1/2, "Range of Age": 34-91, "Mode"=8th decade of life, "Mean"-64.48, "Etiology" Cardiac Origin in majority of cases ("A.F" in 57 percent) and Unknown Origin in 1/4 of cases. "Pain" was find in 95 percent, Grade HI ischemia in only 38 percent of patients on presentation and the others in Grade n. The most common "site of embolic occlusion" was "Femoral Ar." (76 percent). "Simultaneous Embolic Events" were fined in 29 percent. "Embolectomy" was performed in 79 percent (84 percent success rate) and "Primary Amputation" in 12.5 percent. "In hospital Mortality Rate" was fined in 24 percent and "Limb Salvage rate" in 68 percent. In conclusion, there were some logic relationship only between "Limb Salvage rate" and "Ischemic Grading" and also "Delayed diagnosis". There was also some significant direct relationship between "Mortality rate" and "Concomitant Embolic events".
Conclusion: This study was an explorative one that paves the way for further complementary investigations. Although there are many recommendations due to upgrading knowledge, attitude and practice of physicians as well as lay people Besides, the upgrading of educational and curative facilities should not be neglected.

Abstract
Background: To evaluate the ability of Ankle/Brachial Index (ABI), that is a sensitive and specific test for detection of PAD, to foretell the possibility of ischemic heart diseases in diabetic patients.
Materials and Methods: All of diabetic patients who visited in our diabetes research center between May 2000 and May 2001 and were confirmed diabetics since 2 or more years ago were enrolled in the study. The ABI was calculated for all of the patients and their demographic specifications and ischemic heart disease risk factors were recorded. All of the patients refer to perform an exercise test, but 279 patients were conferred to performing stress test. They were containing: 127 patients with ABI =<1.1(group I) and 47 patients with ABI>=1.4(group III) as case groups and, 105 patients with 1.1 60 years (P = 0.02). 238 patients were in group I (25.1 %), 625 patients in group II (65.9 %) and 85 patients in group III (9 %). 52.8% of 125 patients in Group I, 19.6% of 107 patients in group II, and 44.7% of 47 patients in Group III had positive exercise test. I, II (P 0.00)- II , III (P = 0.05) A total of 108 patients from among the 279 patients had positive exercise test (38%), and most of them were from groups I &III. 72.2% of group I , and 52.5% of group II had high blood pressure (P 0.00). Both hypertensive and normotensive patients with ABI =<1.1 & >=1.4 had positive exercise test significantly more than patients with 1.1=1.4 is an independent predictor of coronary artery diseases in diabetic patients especially in those who are hypertensive.

Abstract
Background: Occlusive disease of lower extremity arteries are so common and cause severe stenosis or complete local obstruction in arteries as it need treatment. The treatment could be surgery or interventional procedures like angioplasty or implant of stent. Sometimes such treatments are impossible because of severity or location of complication and cause amputation.The purpose of this study is an assessment about more common locations of arterial obstruction in lower extremities which is necessary for treatment planning and prediction for efficient supplements.
Methods: In this descriptive study from 2000 until 2005, 100 patients with occlusive disease of lower extremity arteries who underwent angiography in medical imaging center of Imam Khomeini hospital in Tehran had been studied according to location of arterial obstructions. In the point of view of homodynamic conditions, obstructions over 70% consider important, so all of these patients had arterial obstruction over 70% up to 100%.
Results: Our findings show that the most common locations of arterial obstruction in lower extremity are superficial femoral artery (47%), arteries of leg (21%) and iliac arteries (19%).
Conclusion: This study can show appropriate assessment of the most common locations of arterial obstruction in lower extremity to predict supplements that may be needed for treatment of these patients.

Abstract
Background: Direct monitoring of arterial pressure using a transducer system is not affordable in most operating rooms and ICU wards in Iran. It is, however, possible to use an aneroid manometer instead, but it is not standardized yet, nor studied enough and its measurements may not be interpretable.
Methods: To study the correlation of the arterial pressure readings between a manometer and a transducer system, systolic and diastolic arterial pressure was measured 105 times using both systems via arterial cannulation in seven patients during surgery. Mean arterial pressure was directly recorded in the transducer system, while it was calculated in the manometer system. In the manometer system, the extension tube was filled with saline halfway from the patient and the other empty end was connected to a manometer. The transducer and the air-fluid interface in the extension tube were positioned at same level. Correlation of the arterial pressures between the systems was tested using linear regression and Pearson correlation.
Results: Mean arterial pressure differed by 2 (1-3) mmHg [mean (CI 95%)] between the systems, however, pulse pressure was lower in the manometer system by 37 (33-41) mmHg. The mean arterial pressure in the transducer system (MAPT) correlated well and linearly with the systolic arterial pressure in the manometer system (SAPM) by R=0.966. Therefore, MAPT can be regarded as a function of SAPM through the following formula: MAPT = (1.03 ´ SAPM) - 7.34.
Conclusion: The mean arterial pressure in the transducer system can be reliably estimated by monitoring the systolic arterial pressure in the manometer system.

Background: Acardiac twin is a
rare complication affecting monozygotic twins and is related to the twin
reversed atrial perfusion sequence (TRAP). The TRAP sequence involves a pump twin perfusing a recipient twin
through vascular anastomosis. Here, we report two cases with different
presentations of acardiac twin.
Case report: The first acardiac
twin was composed of a healthy fetus and a fetus with proximal of trunk, pelvic
and lower limbs without head, neck and arms (acardia acephalus- classic form).
The pregnancy was followed with ultrasonography and pregnancy terminated at 29 weeks, because there
was abnormal doppler of ductus venosus and non-reassuring NST in pump twin. The second
acardiac twin first time was diagnosed at a rotine ultrasonography at 26 weeks gestation as a
healthy fetus and an acardia fetus with a hypoplastic lower limb and intestine
like organ (amorphic mass). The pregnancy following, normal infant was born with
a sac with some loops of the intestine at term. Each two cases were diagnosed
at 26 week and each was
delivered healthy pump twin.
Conclusion: Acardiac twin has different presentation and here
we presented two end of acardia twin presentation with different management and
outcome.

Abstract
Background: Measuring end tidal carbon dioxide (ETCo2) is one of the methods used for estimating arterial carbon dioxide (PaCo2) during general anesthesia. ETCo2 measurements maybe obviate the need for repeating arterial puncture for determination of arterial PaCo2. This study performed to determine the accuracy of ETCo2 levels as a measure of PaCo2 levels in patients undergoing coronary artery bypass graft and also to evaluate variation of the gradient between PaCo2 and ETCo2, peri- cardiopulmonary bypass operation. Methods: In a prospective, cross-sectional study, a total of 40 patients with age 57±11 (35-73) years old undergoing coronary artery bypass graft were enrolled. ETCo2 levels (mmHg) were recorded using side stream capnography at the time of arterial blood gas sampling, before (T0) and after (T1) cardiopulmonary bypass. Results: Mean P(a-ET)Co2 at T0 was 4.3±4.4mmHg, with the mean PaCo2, 33±6mmHg and mean ETCo2, 29±5mmHg and these values at T1 were 4.5±4.1mmHg, 33±5mmHg and 29±2mmHg respectively. There was no variation of the mean gradient (PaCo2-PETCo2) during, before and after cardiopulmonary bypass (p>0.870). Significant correlation was found between ETCo2 and PaCo2 at T0 and T1 (r=0.754 and 0.685respectively and p=0.001). Conclusion: Capnography is a non- invasive and a safe technique for determining arterial PCo2 and for measurements of ETCo2 that correlate well with PaCo2 values in healthy patients undergoing coronary artery bypass graft. ETCo2 measurements maybe sufficient measures of PaCo2 in selected patients and obviate the need for repeatingarterial blood gas determination. Further study is warranted.

Abstract
Background: Arterial insufficiency is a well-recognized etiology of erectile dysfunction. Moreover, nowadays it is appreciated that it can herald silent coronary artery disease in involved patients. However color Doppler study of penis with intracavernosal injection (ICI) of Papaverin, as a helpful diagnostic study, is somehow time consuming and technically demanding, as a result, radiologists are reluctant to accomplish. Hence, in a search for more plausible parameters, we were determined to validate PSV in flaccid state for predicting possible arterial insufficiency in patients.
Methods: In a cross sectional study to evaluate diagnostic tests, accomplished in Hasheminejad Urology center in Tehran throughout 2011, we studied 59 patients with the complaint of erectile dysfunction. They were referred to our ultrasound clinics by urologists in order to undergo color Doppler study of penis by ICI of Papaverin. They were studied comprehensively before and after injection. Primary and secondary diagnostic criteria of arterial disease in color Doppler and consequently the physiologic event of full erection were designated as gold standard diagnostic considerations. The resulted data were matched and analyzed with SPSS software.
Results: Fifty nine patients underwent the study, with the mean age of 45.6 ± 13.1 (24 to 74 year old). Twenty two cases revealed normal study (non-organic causes as 37.3%), 29 were classified as venous leakage, and eight of them demonstrate arterial insufficiency in the study. A flaccid state PSV of 10.5 cm/s as cut off had a sensitivity of 93.8%, specifity of 91.3% and negative predictive value of 93.8% to predict arterial disease.
Conclusion: A flaccid state PSV of 10.5 has a suitable statistical value to proclaim arterial insufficiency in cavernosal arteries in patients with erectile dysfunction as a complaint.

Abstract
Background: Nausea and vomiting is one of the most important complications in chemotherapy. Serotonin and dopamine are important neurotransmitters in nausea and vomiting. It seems that oxygen therapy and increase oxygen saturation can cause decrease these neurotransmitters. The aim of this study was to investigate the relationship between arterial oxygen saturation (SaO2) of patients and chemotherapy-induced nausea and vomiting.
Methods: A descriptive-analytical study was performed in Koosar Hospital in Semnan, Iran, from 19 September 2013 to 25 April. At first, SaO2 of 30 patients in three periods (pre, during and post chemotherapy) were measured. Severity of nausea and vomiting in three days after chemotherapy was measured with an index of nausea, vomiting and retching (Rhodes Index). Also during chemotherapy, anxiety and depression of patients was measured with Hospital Anxiety and Depression Scale (HADS).
Results: In this study thirty patients were evaluated. Most of them were women (66%) with mean age of 55.07±11.9 years old. The most common cancer in patients was breast cancer (46.7%). Mean of SaO2 was 92.1%±3.4 that was not significant difference during the chemotherapy. Mean of nausea and vomiting severity in first day of chemotherapy was (3.27±5.5), in second day was (4.5±6.2) and in third day was (7.2±8.7). The Pearson correlation coefficient did not show the relationship between oxygen saturation with severity of nausea and vomiting (P>0.05). Although severity of anxiety of patients was significant relationship with nausea and vomiting in third day (P=0.03).
Conclusion: In this study there was no significant relationship between oxygen saturation and severity of nausea and vomiting, but anxiety of patients was related to nausea and vomiting in third day. Chemotherapy-induced nausea and vomiting was more common in third day and it seems that further research is needed for relationship between oxygen saturation and nausea and vomiting in third day of treatment.
