The Effect of Very Low Concentrations of Ethanol on Microvascular Artery and Vein Anastomosis: An Experimental Study

OBJECTIVES

This study investigated the effect of very low concentrations of ethanol on artery and vein anastomosis. Also, it was aimed to determine the appropriate ethanol concentration to be used in vasospasm.

METHODS

Rats were divided into five groups of eight rats, each group, as follows: Group i: saline; Group ii: 2.5% ethanol; Group iii: 5% ethanol; Group IV: 7.5% ethanol; and Group V: 10% ethanol. During the femoral artery and vein anastomosis, 1ml of the agent was used for irrigation in each group. Vessel diameters were measured before the anastomosis, at the fifth and 15th minutes, and the third week after the anastomosis. Histopathological samples were taken in the third week.

RESULTS

In Groups ii and iii, the mean vessel diameters were found to increase 15th minute. Also observed was an increase in mean vessel diameter that continued in the third week. Although acute vasodilation was detected in Groups IV and V, arterial and venous thrombosis was observed in the third week. Intima and media thickness decreased in Group ii, while it increased in Group iii. Perivascular inflammation and fibrosis increased as the ethanol concentration increased.

CONCLUSION

2.5% ethanol causes acute and prolonged vasodilation and does not cause endothelial cell damage, perivascular inflammation, and fibrosis. 2.5% ethanol will be a powerful alternative use in many situations that occur with vasospasm.

Effect of Reduction Mammoplasty on Insulin and Lipid Metabolism in the Postoperative Third month: Compensatory Hip Enlargement

BACKGROUNDS

The positive effects of reduction mammoplasty on metabolic profile have been shown in a limited number of studies. This study objective to reveal the effects of reduction mammoplasty on metabolic profile and anthropometric measurements.

SUBJECTS AND METHOD

The study was prospectively conducted on 42 patients who were operated between April 2019 and March 2020. Fasting plasma glucose, fasting plasma insulin, total cholesterol, triglyceride, high-density lipoprotein and low-density lipoprotein cholesterol, HgA1c, homeostasis model assessment scores, adiponectin, leptin, and resistin levels were evaluated. In addition, age, height, weight, body mass index; breast, chest, waist, hip circumference; waist-hip ratio, and bilateral breast resection tissue weights were recorded. Data and blood samples were collected one hour before the operation, 6 and 12 weeks after the operation.

RESULT

The patients' mean age was 43.14±10.24, and their average height was 159.42±4.96 cm. The excised bilateral dermo fatty tissue weight was 1435.85±721.16 g. At the postoperative 40th day a decrease in leptin (p = 0.001), resistin (p =0.008), glucose (p = 0.021) and insulin resistance values (p=0.013) stated. There was an increase in adiponectin (p < 0.001) and HDL (p = 0.013) levels at the postoperative 40th day. In the postoperative third month, these data returned to the previous levels that were measured before operations. However, an increase in hip circumference (p = 0.034) and a decrease in waist-hip ratio (p < 0.001) was detected in third month. Also, there was no difference in body mass index and weight compared to pre-operation.

CONCLUSION

After reduction mammoplasty, compensatory fat growth in the hip area, an increase in the hip circumference, and a decrease in the waist-hip ratio were observed in the postoperative third month.
