Doppler flowmetry in determination and evaluation of blood flow characteristics in anterior abdominal wall vessels during lipoabdominoplasty
Journal Title: Серце і судини - Year 2018, Vol 0, Issue 4
Abstract
The aim — to determine the possibility of using Doppler blood flow in the vessels of the anterior abdominal wall in order to improve the results and develop new methods for treating patients with cosmetic defects of the anterior abdominal wall during lipoabdominoplasty. Materials and methods. Investigation of the vessels of the anterior abdominal wall using Doppler scan was performed in 58 patients. The average age of patients was 38.2 ± 2.8 years. All patients were either obese with grade I, II or overweight (average body mass index 30.2 ± 1.5). Patients were examined in the preoperative period in accordance with the standards of the Ministry of Health of Ukraine. All patients had primary lipoabdominoplasty. Doppler flowmetry was performed before surgery and on day 14 after lipoabdominoplasty to assess the blood supply to the anterior abdominal wall. Results and discussion. Most muscle‑skin perforators were located at distance of 5.2 ± 0.3 cm from the median line. In the preoperative period in average 6.12 ± 1.31 perforators were detected in one patient. The average diameter of the vessels was 1.55 ± 0.8 mm. In the postoperative period, 3.25 ± 1.27 perforators with a diameter of 1.68 ± 0.75 mm were detected, which confirms the preservation of arterial branches after surgery. The average diameter of the vessels was 1.68 ± 0.75 mm, which confirms the preservation of the arterial branches after the operation. The increase in vessel caliber was statistically significant (p < 0.05). The average blood flow velocity in the vessels increased by 56 % (from 21.8 ml/min before surgery to 34.3 ml/min after surgery, p < 0.05). Vasodilation changes are explained by a decrease in the blood supply to the tissues caused by surgical trauma, a decrease in the total number of perforators and an overload of the residual vessels. Conclusions. Preoperative determination of perforated vessels helps to estimate the possibilities of resection of the flaps, determine the areas of possible dissection and volume of the entire operation. The risk of complications after abdominoplasty can be reduced by a limited flap dissection and the preservation of perforated vessels in the flap. It has been shown that in the course of lipoabdominoplasty perforation vessels with a diameter of more than 1 mm in periumbilical and upper lateral quadrants are not destroyed. During Doppler study in the postoperative period, an increase in the caliber of the arteries (p < 0.05) and the rate of blood flow in them was found to be 56 % (p > 0.05).
