ABSTRACT
PURPOSE: To investigate the paths of thoracic epidural catheters in children, this retrospective study was performed. METHODS: We investigated 73 children aged 4 to 12 (mean ± SD 7.8 ± 2.3) years, who underwent the Nuss procedure for pectus excavatum repair under combined general and epidural anesthesia over a 5-year period at Tokyo Metropolitan Police Hospital. Following induction of general anesthesia, we inserted a radiopaque epidural catheter via the T5/6 or T6/7 interspace and advanced for 5 cm cephalad in the thoracic epidural space. We evaluated the paths of the epidural catheters on plain chest radiographs after surgery. RESULTS: The median level for the catheter tip location was T3 (range C6-T7), while the median number of vertebrae crossed by the catheter tips was 2.5. In most children, the catheters advanced straight for the first 2-3 cm (1-1.5 vertebrae) in the thoracic epidural space. However, they continued to advance straight in only 25 children, while they exhibited curved or coiled paths in the remaining 48. The catheter tips were located at higher levels in children with straight epidural catheter paths [median (range) T2 (C6-T4)] than in those with curved or coiled paths after the initial 2-3 cm [median (range) T4 (T2-T7)] (p < 0.0001). CONCLUSIONS: Our findings indicate that the course of epidural catheters in children is unpredictable after the first 2-3 cm in the thoracic epidural space. Clinicians should be aware of such findings, although further studies are required for confirmation.

We report 2 cases of growth spurt-related recurrence after Nuss procedure. Each of the 2 cases underwent bar insertion at the age of 6 and 11 years, respectively. The support bar was removed 2 years later followed by severe redepression during the growth spurt. One patient underwent redo Nuss procedure elsewhere. The other patient was diagnosed as idiopathic precocious puberty and is in treatment. The possibility of growth spurt-related recurrence must be explained to those who undergo early correction before surgery, and follow-up is mandatory at least until patients' puberty is over.

Patients with silicon gel-injected breasts sometimes appear even now, demanding removal of this foreign body. These requests are often challenging for us-the removal leaves distortion of the breast contour. Musclocutaneous flap transfer is a good method for reconstruction, but scar formation for flap harvest is a problem. Most patients are reluctant to accept these scars. Reconstruction with prostheses has been another method. But the absence of subcutaneous tissue and degenerated muscle make implantation difficult. For one of these patients, the authors applied a method for breast reconstruction with perforator-based inframammary flap. After the removal of the siliconoma with surrounding degenerated tissues, a crescent-shaped skin flap was designed on the inframammary area. Preserving perforators into the flap, it was elevated with adipose tissue. After the skin was de-epthelized, the adipose tissue and skin flap were turned over to make the breast protrusion. The donor site is closed primarily. Ten months after the operation, there was little atrophy of the reconstructed breast, and the patient is satisfied with the result, especially with the softness of the reconstructed breast. Although this method has limitation for volume, less morbidity for donor site and volume reduction in inframammary area are advantageous. In conclusion, this inframammary flap seems to be a good tool for breast surgery.
