Free pedicled transverse rectus abdominis myocutaneous (TRAM) flap breast reconstruction is often advocated as the procedure of choice for autogenous tissue breast reconstruction in high-risk patients, such as smokers. However, whether use of the free TRAM flap is a desirable option for breast reconstruction in smokers is still unclear. All patients undergoing breast reconstruction with free TRAM flaps at our institution between February of 1989 and May of 1998 were reviewed. Patients were classified as smokers, former smokers (patients who had stopped smoking at least 4 weeks before surgery), and nonsmokers. Flap and donor-site complications in the three groups were compared. Information on demographic characteristics, body mass index, and comorbid medical conditions was used to perform multivariate statistical analysis. A total of 936 breast reconstructions with free TRAM flaps were performed in 718 patients (80.9 percent immediate; 23.3 percent bilateral). There were 478 nonsmokers, 150 former smokers, and 90 smokers. Flap complications occurred in 222 (23.7 percent) of 936 flaps. Smokers had a higher incidence of mastectomy flap necrosis than nonsmokers (18.9 percent versus 9.0 percent; p = 0.005). Smokers who underwent immediate reconstruction had a significantly higher incidence of mastectomy skin flap necrosis than did smokers who underwent delayed reconstruction (21.7 percent versus 0 percent; p = 0.039). Donor-site complications occurred in 106 (14.8 percent) of 718 patients. Donor-site complications were more common in smokers than in former smokers (25.6 percent versus 10.0 percent; p = 0.001) or nonsmokers (25.6 percent versus 14.2 percent; p = 0.007). Compared with nonsmokers, smokers had significantly higher rates of abdominal flap necrosis (4.4 percent versus 0.8 percent; p = 0.025) and hernia (6.7 percent versus 2.1 percent; p = 0.016). No significant difference in complication rates was noted between former smokers and nonsmokers. Among smokers, patients with a smoking history of greater than 10 pack-years had a significantly higher overall complication rate compared with patients with a smoking history of 10 or fewer pack-years (55.8 percent versus 23.8 percent; p = 0.049). In summary, free TRAM flap breast reconstruction in smokers was not associated with a significant increase in the rates of vessel thrombosis, flap loss, or fat necrosis compared with rates in nonsmokers. However, smokers were at significantly higher risk for mastectomy skin flap necrosis, abdominal flap necrosis, and hernia compared with nonsmokers. Patients with a smoking history of greater than 10 pack-years were at especially high risk for perioperative complications, suggesting that this should be considered a relative contraindication for free TRAM flap breast reconstruction. Smoking-related complications were significantly reduced when the reconstruction was delayed or when the patient stopped smoking at least 4 weeks before surgery.
The incidence of postoperative abdominal bulge, hernia, and the ability to do sit-ups was reviewed in a series of 268 patients who had undergone free TRAM (FTRAM) or conventional TRAM (CTRAM) flap breast reconstruction. Minimum follow-up was 6 months. Patients were divided into four groups: unilateral FTRAM (FT1P; n = 123), double-pedicle bilateral FTRAM (FT2P; n = 45), single-pedicle CTRAM (CT1P; n = 40), and double-pedicle or bilateral CTRAM (CT2P; n = 60). The incidence of abdominal bulges (3.8 percent) and hernia (2.6 percent) was similar in the four groups. Synthetic mesh, however, was required for reinforcement of donor site closure twice as often in the CTRAM patients. The ability to perform sit-ups was greatest in the FT1P group (63.0 percent), slightly lower in the CT1P group (57.1 percent), still lower in the FT2P group (46.2 percent), and lowest in the CT2P group (27.1 percent; p = 0.0005). Patients reconstructed with an FTRAM flap were more likely to be able to do sit-ups (58.3 percent) than were those reconstructed with a CTRAM flap (38.2 percent; p = 0.0074). Patients who had only one muscle pedicle used were more likely to be able to do sit-ups (61.7 percent) than were those who had two muscle pedicles used (35.6 percent; p = 0.0003). We conclude that the incidence of abdominal bulge or hernia is relatively independent of the type of TRAM flap used and the number of muscle pedicles harvested. On the other hand, postoperative abdominal strength, as measured by the ability do sit-ups, is influenced significantly by both of these factors.
Over the past decade, free-tissue transfer has greatly improved the quality of oncology-related head and neck reconstruction. As this technique has developed, second free flaps have been performed for aesthetic improvement of the reconstructed site. This study evaluated the indications for and the success of second free flaps. Medical files for patients who underwent second free flaps for head and neck reconstruction at the University of Texas M.D. Anderson Cancer Center, from May 1, 1988 to November 30, 1996, were reviewed. The flaps were classified as being either immediate (done within 72 hr) or delayed (done within 2 years) reconstructions. Indications, risk factors, recipient vessels, outcome, and complications were analyzed. Of the 28 patients included in this study, 12 had immediate (nine as salvage after primary free flap failure, and three for reconstruction of a soft-tissue defect), and 16 had delayed second free flaps (two for reconstruction of a defect resulting from excision of recurrent tumors, and 14 for aesthetic improvement). Reconstruction sites included the oral cavity in 18 patients; the midface in six; the skull base in two; and the scalp in two. The success rate for the second free flaps was 96 percent. Five patients had significant wound complications. In a substantial number of cases, identical recipient vessels were used for both the first and second free flaps. The authors conclude that second free flaps can play an important role in salvaging or improving head and neck reconstruction in selected patients. In many cases, the same recipient vessels can be used for both the first and second flaps.
All patients undergoing breast reconstruction with free transverse rectus abdominis musculocutaneous (TRAM) flaps from February 1989 to November 1992 were registered into a computerized database and followed prospectively. There were 211 free TRAM flap breast reconstructions in 163 patients; 48 reconstructions were bilateral. A muscle split technique was used in 108 of 211 reconstructions (51%). Total flap loss occurred in 3 of 211 reconstructions for a success rate of 99%. Complications occurred in 81 of 211 reconstructions (38%). Fat necrosis or partial flap loss occurred in 15 of 211 (7%). Hernia or bulge occurred in 11 patients (5%). The bulge/hernia rate tended to be lower in the muscle split group (4 of 108 [4%]) than in those who did not have muscle split procedures (7 of 103 [7%]), whereas the fat necrosis rate was slightly higher in the former group (9 of 108 [8%]) than in the latter (6 of 103 [6%]). Neither difference was statistically significant. However, patients who currently or previously smoked cigarettes did have a significantly higher incidence of fat necrosis: 12 of 99 smokers (12%) had fat necrosis compared with 3 of 112 nonsmokers (3%; p = 0.02).
The purpose of this study was to evaluate the use of free-tissue transfers for the reconstruction of radiation-induced complex injuries. The case files for patients who underwent reconstruction for radiation-induced injuries between May 1988 and November 1995 at The University of Texas M.D. Anderson Cancer Center were retrospectively reviewed. Thirty patients in whom 33 free flaps were done were included. Radiation-induced defects were located in the head and neck (n = 23), extremities (n = 4), chest wall (n = 2), and inguinal area (n = 1). The mean period between irradiation and injury was 78 months (range: 4 months to 38 years). Free-tissue transfer was successful in 97 percent (32/33) of patients. The overall complication rate was 40 percent (12/30). Flap donor sites included the fibula (n = 12), latissimus dorsi (n = 6), rectus abdominis (n = 6), iliac crest (n = 4), scapula (n = 3), and radial forearm (n = 2). Large-caliber vessels in the cervical, axillary, or inguinal regions were most commonly used to revascularize flaps. Vein grafts were used in five cases for the artery (2/5) or vein (3/5). Pedicle thrombosis occurred in three cases in recipient vessels located within the irradiated field. Two flaps were salvaged; one was lost, and the patient required a second free-flap reconstruction. The mean follow-up was 40 months (range: 2.5 to 83 months). The disease-free survival rate was 67 percent (20/30), local failures occurred in 10 percent (3/30) of patients, and 23.3 percent (7/30) of patients either died or were lost to follow-up. Healing of radiation-induced wounds may be achieved using free-tissue transfers, but complications are frequent. Large-caliber irradiated vessels may be used to revascularize flaps, but there may be an increased risk of pedicle thrombosis.
The use of breast implants in irradiated patients is controversial. Recently, 39 irradiated implants were compared with 338 nonirradiated implants in 297 patients between January of 1975 and October of 1994 at The University of Texas M. D. Anderson Cancer Center. Tissue expanders and follow-up time of less than 6 months excluded patients from the study. Five groups of patients were identified. Group 1 consisted of 7 patients and 7 implants who received postoperative adjuvant radiotherapy after implant placement. Group 2 consisted of 5 patients and 7 implants who received preoperative adjuvant radiotherapy prior to implant placement. Groups 3 and 4 consisted of 2 and 12 patients (2 and 19 implants) placed beneath latissimus dorsi flaps who had postoperative and preoperative adjuvant radiotherapy, respectively. Group 5 contained 4 patients with 4 implants placed beneath a transverse rectus abdominis myocutaneous (TRAM) flap who had preoperative radiotherapy. All implants were placed submuscularly or beneath autogenous flaps. The average irradiated breast received 50 Gy. For statistical purposes, two categories were identified. Capsular contracture (Baker III or greater), pain, exposure, and implant removal in 6 of 14 implants that received radiotherapy were compared with similar complications in 33 of 266 implants without irradiation (p = 0.001). The second category contained 10 complications in 25 implants placed beneath autogenous reconstructions with radiotherapy compared with 6 of 72 similar complications in implants placed beneath autogenous reconstructions without radiotherapy (p = 0.000). Results showed that irradiation has significant negative effects on the reconstructive outcome with implants. Autogenous reconstruction did not appear to offer a protective role when placed over implants.(ABSTRACT TRUNCATED AT 250 WORDS)
Ketorolac is frequently used as an adjunct for postoperative pain relief, especially by anesthesiologists during the immediate postoperative period. It can be used alone as an analgesic but is more often used to potentiate the actions of narcotics such as morphine or meperidine in an attempt to reduce the total dose and side effects of those drugs. The manufacturer of ketorolac cautions against its use in patients who have a high risk of postoperative bleeding, for fear of increasing the risk of hematoma, but the risk in transverse rectus abdominis musculocutaneous (TRAM) flap patients has never been reported. In a study of 215 patients who had undergone TRAM flap breast reconstruction, it was determined that patients who received intravenous ketorolac (n = 65) as an adjunct to their treatment with morphine administered by use of a patient-controlled analgesia device required less morphine (mean cumulative dose, 1.39 mg/kg) than did patients who did not receive ketorolac (n = 150; mean cumulative dose, 1.75 mg/kg; p = 0.02). There was no increase in the incidence of hematoma in patients who were treated with ketorolac. The data presented in this study suggest that the use of intravenous ketorolac does reduce the need for narcotics administration in patients undergoing TRAM flap breast reconstruction, without significantly increasing the risk of hematoma.
