This paper presents two case reports on thermal injury to a breast reconstructed by the TAPIA method. In both cases the injuries were caused by excessive sun exposure. Thermal injury to flaps used in breast reconstruction has previously been described but most commonly in abdominal flaps, which may be due to the relative high frequency of this type of reconstructions. Reports of thermal injury to reconstructions using the Latissimus Dorsi flap are rare. The injuries previously described are most often caused by severe heat exposure. The thoracodorsal artery perforator (TAP)-flap can be used as an alternative to the Latissimus Dorsi flap but it may be more susceptible to thermal insult due to the total denervation, the restricted blood supply and the limited thickness of the flap. Precautions are recommended to avoid this type of injury. Gland Surg 2017;6(1):110-113 gs.amegroups.com
Case 2A 48-year-old woman diagnosed with invasive ductal carcinoma in 2001 was treated by a right-sided mastectomy without adjuvant therapy. The patient was a non-smoker and apart from well-treated hypertension she had no comorbidity. She was reconstructed by the TAPIA method in April 2013 using a 365 cc Becker implant. She was discharged day 11 after an uneventful postoperative course.The patient presented with a satisfying result at the first postoperative control in the outpatient clinic three weeks after surgery. However, one week later she presented with a full-thickness skin burn, measuring 8 cm × 6 cm ( Figure 2A). She too had been exposed to the sun in hot weather wearing a dark shirt not exposing the flap to direct sunlight. The defect was debrided, revealing a viable flap underneath ( Figure 2B). We applied negative pressure wound therapy for 14 days and then covered the defect with a full-thickness skin graft ( Figure 2C). The nipple areola complex have since been reconstructed using a skate-flap and a tattoo ( Figure 2D).
DiscussionThermal injury following breast reconstructions is a rare incident. The first case was reported more than two decades ago and since only few cases have been reported and compiled in two literary reviews (9,11). Most of the published material covers complete autologous reconstructions using either DIEP or TRAM flaps.The most frequent cause of thermal injury to the flaps seems to be heat exposure due to sunlight most often when the patient has been wearing dark clothes or bathing suits (3,9). The extent of the injury varies but most published cases have been treated conservatively. Approximately 16% required surgical revision and application of a skin graft (11).The etiology behind the increased risk of thermal injury is multi factorial. It is well documented that the sensibility of a reconstructed breast is scarce, especially in the initial period following reconstruction (9). The reconstruction seems to be most susceptible to thermal injury in the early postoperative period. However, the flaps tend to regain some autoregulation and sensitivity over time, however the duration may depend...
