ABSTRACT

BACKGROUND: It is controversial issue that heparin decreases thrombosis for microsurgical anastomosis, and its effective role is under discussion. This study is for proving whether low-dose heparin is preventing thrombosis in free flap reconstruction. METHODS: Through chart reviews of 134 patients, using low-dose heparin for free tissue transfer from 2011 to 2016, retrospective analysis was performed. 33 patients received low-dose heparin therapy after surgery. And 101 patients received no-heparin therapy. Complications included flap necrosis, hematoma formation, dehiscence and infection. RESULTS: In no-heparin therapy group, comparing the flap necrosis revealed 16 cases (15.84%). And, flap necrosis was 6 cases (18.18%) in low-dose heparin therapy group. The statistical analysis of flap necrosis rate showed no significant difference (p=0.75). The results showed that there was no significant difference of flap necrosis rate between two groups. CONCLUSION: In this study, patients in the low-dose heparin group had no significantly lower rates of flap failure compared with no-heparin group. This suggests that low-dose heparin may not prevent thrombosis and subsequent flap failure to a significant extent.

ABSTRACT

According to a great desire for facial rejuvenation, dermal filler is promising for improving people's appearance without surgery. In a society of plastic surgery, injection of dermal filler is one of the most common procedures for a younger appearance. An increase in patients who have filler injection has been paralleled by a rise in various adverse reactions. Formation of inflammatory or infected nodules is one of the most common long-term complications. Infections can be increased because of improper disinfection of the patient's skin, a poor injection technique, decreased general immunity, and the presence of pathogens. The majority of bacteria are aerobic or facultative aerobic bacteria. This expectation of pathogens is critical for deciding on the antibiotic treatment before confirming the pathogen by microbial culture. The authors experienced unusual culture results in a patient with a chronic inflammatory nodule with abscess formation. The authors report a unique Aspergillus-cultured infection after filler injection.
