ABSTRACT
Objective:To evaluate the efficacy of SVF-gel and Coleman fat in facial volume filling.Methods:This investigation presents a retrospective study of facial fat transplantation in 186 patients (114 cases of SVF-gel transplantation and 72 cases of Coleman fat transplantation) from December 2018 to September 2020 in Shanghai Basilica Clinic. Patient satisfaction was evaluated with the satisfaction questionnaire and secondary operation rates were tallied.Results:Facial augmentation and contour were improved in all patients. The satisfaction rate among the patients in the SVF-gel group was 93.0%, while that among the patients in the Coleman fat transplantation group was only 56.9% (χ 2=8.694, P<0.05). Patients in the SVF-gel group experienced less swelling and there was a lower secondary operation rate in the SVF-gel group than those in the Coleman fat transplantation group (1.75% vs 18.1%) (χ 2=13.467, P<0.001). Conclusions:SVF-gel has obvious advantages over traditional fat transplantation in facial volume filling and rejuvenation.
ABSTRACT
Recently,clinicians pay more and more attention to the treatment effects related to individual differences.Individualized treatment of hepatic carcmoma is becoming the focus of clinical treatment and basic research increasingly.The individualized treatment of surgery,chemotherapy with radiotherapy,targeted therapy,immunotherapy and gene therapy have become new ways for further improving the prognosis of liver cancer.
ABSTRACT
Objective To assess effects of the different retention time and temperature of the tumescent fluid on surgical blood loss in tumescent liposuction.Methods 20 patients with localized fat deposits received tumescent liposuction and the blood loss were calculated and compared between two treated groups.Results The mean surgical blood loss in 20 patients was (50.27± 18.56) ml with range (21.42-77.26) ml.The blood loss in liposuction with 0.5 hour retention and no retention of tumescent fluids was (19.89±7.52) ml and (26.25±12.07) ml,respectively; the blood loss in liposuction with heated (37℃) and non-heated tumescent fluid (23℃) was (28.60±6.07) ml and (29.93±9.06) ml,respectively.Conclusions A half hour retention of tumescent fluid in subcutaneous tissue after injection could reduce the surgical blood loss and the blood loss amount does not increase in the usage of a pre-heated tumescent fluid.
ABSTRACT
Objective To observe the feasibility and effects of tumescent anesthesia on out-patients base in large-volume liposuction. Methods A total of 184 times of large volume liposuction in 154 patients were performed under tumescent technique with 0.05 % lidocaine and 1∶500,000 epinephrine. The whole abdomen, hypochondrium and waist areas or the posterior, lateral, medial aspects of the legs and the subgluteal regions were covered in one operation. The total injected tumescent liquid is from 2 200 ml to 5250 ml, the average was 2 730 ml. The dose of lidocaine was less than 40 mg/kg body weight or less than 2.4g in total. Results Some patients felt little discomfort during tumescent liquid injection, but all patients tolerated the procedure well under lower-concentration lidocaine without assistance of any analgesics or sedatives, the suctioned volume was 1 900～4 200 ml (the average 2 568 ml) and the supernatant of the suctioned volume was 1 200～3 400 (the average 2 036 ml). Conclusions It is practicable to perform large-volume liposuction using lower-concentration lidocaine tumescent technique with good persistent results.
