Choice of recipient vessels in muscle-sparing transverse rectus abdominis myocutaneous flap breast reconstruction: A comparative study

BACKGROUND: Thoracodorsal vessels (TDVs) and internal mammary vessels (IMVs) have both been widely employed as recipient vessels for use in free muscle-sparing transverse rectus abdominis myocutaneous (MS-TRAM) flaps. However, whether TDVs or IMVs are preferable as recipient vessels for autologous breast reconstruction with a free MS-TRAM flap remains controversial. The purpose of this study was to compare the clinical outcomes when TDVs were used as recipient vessels to those obtained when IMVs were used as recipient vessels for autologous breast reconstruction with a free MS-TRAM flap. METHODS: A retrospective matched-cohort study was performed. We retrospectively reviewed data collected from patients who underwent a free MS-TRAM flap for autologous breast reconstructions after mastectomy between March 2003 and June 2013. After a one-to-one matching using age, 100 autologous breast reconstructions were selected in this study. Of the 100 breast reconstructions, 50 flaps were anastomosed to TDVs and 50 to IMVs. Patient demographics and clinical outcomes including operation time, length of hospital stay, postoperative complications, and aesthetic score were compared between the two groups. RESULTS: No statistically significant differences were found between the two groups in patient demographics and clinical outcomes, including the complication rates and aesthetic scores. There were no major complications such as total or partial flap loss in either group. CONCLUSIONS: The results of our study demonstrate that both TDVs and IMVs were safe and efficient as recipient vessels in terms of the complication rates and aesthetic outcomes.

The Anatomical Variations of DIEA (Deep Inferior Epigastric Artery) in Microsurgical Breast Reconstruction: Clinical Report

Autologous breast reconstruction after mastectomy in breast cancer patient is now increasing. The deep inferior epigastric artery (DIEA) free flap is well known as an ideal donor site for the microsurgical breast reconstruction. The branching pattern of the DIEA was well described in the literature. In that study, DIEA has three branching patterns near the arcuate line. We describe a case in which branching variation of the DIEA before entering the posterior surface of the rectus abdominis muscle. In three cases, DIEA originated from the external iliac artery ascended as a double trunk at 1cm, 2cm, and 4cm above the originating point, respectively. In one case, DIEA ascended as a single trunk along the linea alba toward to the umbilicus until it supply overlying subcutaneous tissue. Preoperative 3D computed tomographic angiography to identify the anomaly is recommended and meticulous dissection to the originating point of DIEA is needed.

Transcutaneous Oxygen Pressure to Predict Wound Healing in Mild Diabetic Feet

PURPOSE: Microcirculation of diabetic patients is commonly comporomised, regardless of the condition of the macrocirculation. Therefore, direct tissue oxygenation measurement is recommended in determining tissue viability and predicting wound healing potential. This study was designed to determine cut-off value of the tissue oxygenation in predicting wound healing in diabetic foot patients. METHODS: This study included 41 feet of 41 diabetic foot patients who were treated in the Diabetic Wound Center of author's institution between January and June, 2009. Main inclusion criteria were type 1 or 2 diabetes and a foot ulcer (duration > 3 weeks) and ulcer area(from 1cm2 to 4cm2). Measurements of the area of diabetic foot ulcer were carried out before treatment. Transcutaneous oxygen pressure(TcpO2) was measured at adjacent site of ulcer. The healing wound was defined as complete wound closure within 12 weeks. RESULTS: Average diabetic foot ulcer areas with healing and nonhealing wounds were 2.67+/-0.76 and 2.59+/-0.75 cm2, respectively. There was no significant difference in the wound area between the groups. Average foot TcpO2 in healing and nonhealing wounds were 68.56+/-23.07 and 30.98+/-16.66mmHg, respectively(p<0.01). The rate of healing wound increased as TcpO2 increased. In particular, TcpO2 lower than 40mmHg and higher than 40mmHg showed the most significant difference(wound healing rates of 25% and 71%, respectively). CONCLUSION: Based on the results of the study, the minimal TcpO2 value thought to be required for adequate wound healing in diabetic wounds(cut-off value) is 40 mmHg.

Carpal Tunnel Syndrome by Ganglion: A Case Report

PURPOSE: Carpal tunnel syndrome is the most common peripheral compressive neuropathy. Most cases are idiopathic, but rarely carpal tunnel syndrome can be associated with a ganglionic mass. We report our recently encountered experience of surgical treatment of carpal tunnel syndrome caused by a simple ganglionic mass. METHODS: A 53-year-old man presented with chief complaints of numbness and hypoesthesia of his left palm, thumb, index finger, long finger, and ring finger of one and half month duration. Physical examination revealed positive Tinnel's sign without previous trauma, infection or any other events. Electromyography showed entrapment neuropathy of the median nerve. Magnetic resonance imaging(MRI) showed an approximately 2.0cm-sized mass below the transverse carpal ligament. Upon surgical excision, a 1 x 1.5cm2 mass attached to the perineurium of the median nerve and synovial sheath of the flexor digitorum superficialis and redness and hypertrophy of the median nerve were discovered. With surgical intervention, we completely removed the ganglionic mass and performed surgical release of the transverse carpal ligament. RESULTS: The pathology report confirmed the mass to be a ganglion. The patient exhibited post-operative improvement of his symptoms and did not show any complications. CONCLUSION: We present a review of our experience with this rare case of carpal tunnel syndrome caused by a ganglionic mass and give a detailed follow-up on the patient treated by surgical exploration with carpal tunnel release.
