Breast reconstruction following mastectomy: an update.

Breast reconstruction today is a realistic and vital part of total breast cancer treatment. All physicians should be well informed on current methods of reconstruction so that they can present the facts to their patients in an encouraging, yet realistic manner. Recent developments in breast reconstruction after mastectomy have included the increase utilization of immediate breast reconstruction at the time of mastectomy, the improvement and refinement of the TRAM flap, the increased use of the "free" flap transfer of the TRAM flap which increases blood supply to the flap, texturing of implants which appears to increase their stability on the chest wall and reduce the incidence of capsular contracture or firmness, and the introduction of the newer autogenous tissue methods including the LTTF, gluteal, and latissimus dorsi flaps. Plastic surgeons are charged with the task of becoming proficient in breast reconstruction procedures in order to offer the mastectomy patient a safe, realistic facsimile breast that will be trouble free. Fortunately, there are several good options for restoring the breast after mastectomy. The method of reconstruction should be chosen by matching the desires of informed patients with the indications and contraindications in each case. In general, silicone reconstruction is expedient and satisfactory in most patients. However, it cannot compete with autogenous tissue transfer for severe chest wall defects, covering irradiated areas, creating a large, ptotic breast, or providing a natural appearing, soft breast mount.

TRAM flap safety optimized with intraoperative Doppler.

Anatomic studies have clearly documented the variable position of the deep superior epigastric vessels in the rectus abdominis muscle. In our opinion, only that part of the rectus abdominis muscle containing the vascular pedicle should be transposed with the TRAM flap. The Doppler probe provides a simple method of identifying the dominant intramuscular vascular axis. It consistently alerts the surgeon to any unusual position of a vessel at the costal margin or within the rectus abdominis muscle. This knowledge enables a conservative yet safe dissection of the vascular pedicle, rectus abdominis muscle, and its sheath. This in turn will enable a competent abdominal closure. The Doppler technique is safe, simple, quick, noninvasive, familiar to most surgeons, and applicable to all patients.

Autogenous tissue reconstruction in the mastectomy patient. A critical review of 300 patients.

The transverse abdominal island flap operation was the method of breast reconstruction after mastectomy and in chest wall reconstruction in 300 patients from September 1980 to July 1986. In 58% (221 of 383 breast reconstructions), the breast mound was formed in a single operation and required no further revision. Only 18 reconstructed breasts required modification after 1 year. Symmetry was achieved without altering the opposite breast in 113 (52% of the 217 unilateral reconstructions). Complications included one total flap loss (0.3%) and 18 partial flap losses (6%). There was one lower abdominal hernia (0.3%) and two small defects in the upper anterior rectus sheath (0.8%). Lower abdominal wall laxity occurred in two patients (0.8%), one requiring repair. As expected, there was some loss of abdominal wall strength after reconstruction but this did not affect sports or work performance in over 90% of patients. Ninety-eight per cent of respondents (272 or 278) judged the operation worth their time and effort. This major operative procedure is indicated only in healthy patients.
