“…The cutaneous perforators of the SDMA have consistent ascending and descending branches. The adjacent ascending branches were anastomosed with the adjacent descending branches to form the axis of the cutaneous chain, which was parallel to the SDMA (14,21). Notably, there is a consistent anastomosis between the dorsal metacarpal arteries to form the transverse arterial network.…”

Background First web-space defect reconstruction is challenging for reconstructive surgeons. The second dorsal metacarpal artery (SDMA) flap is useful in treating hand and finger defects. However, limited studies have used it for the first web-space defects. This study reports a modified SDMA flap to treat first web-space soft-tissue defects. Methods From April 2012 to October 2018, 8 patients underwent a modified SDMA flap transfer (mean flap size, 2 × 3 cm to 4 × 6 cm). The average length of the pedicle was 2.9 cm. On average, the flap was rotated 84°. In 6 patients, full-thickness skin was grafted at the donor sites. The donor site was primarily closed in two cases. Results All wounds were healed without complications of flap failure or donor area-related morbidity. The average follow-up period was 7.9 months, and these patients were satisfied with the functional recovery and cosmetic appearance of the scar area. At the end of follow-up, the average movement range of the metacarpophalangeal joint of the thumb, index finger, and long finger were 84°, 88°, and 87°, respectively, while those of the contralateral thumb, index finger, and long finger were 87°, 88°, and 85°, respectively. The first web of the injured side spanned an average of 73°; the measurement on the contralateral side was 91°. Conclusions The SDMA flap reconstruction is a simple and fast procedure with a wide resurfacing range for large first web-space defects, low donor-site morbidity, and good functional and esthetic appearance.

“…[1][2][3][4][5] Conversely, this perforator flap has a disadvantage of the difficulty associated with finding appropriate perforators due to anatomical variation, and the small, thin cutaneous perforators of the SDMA. [1][2][3][4][5] Presently, the most common method of mapping SDMC perforators has been the conventional HADF using a pencil-type Doppler probe. [10][11][12] HADF is a non-invasive, simple and portable method, which makes it easy to perform in most hospitals.…”

“…In addition, they measured the perforator points using no bony landmark. 1,2 In the current study, all data evaluated were corrected for the length of the metacarpal. Consequently, more than one cutaneous perforator of the SDMA could always be found at the distal one-fourth of the second metacarpal in all hands with the CDU examination.…”

Purpose: The second dorsal metacarpal (SDMC) perforator flap has been widely used for the soft tissue reconstruction of the hand. However, it is difficult to identify the depth and branches of the perforators of the second dorsal metacarpal artery (SDMA) using only handheld acoustic Doppler flowmetry (HADF), which is the most common method. The purpose of this study was to compare the results of examination by color Doppler ultrasonography (CDU) with those of HADF and to evaluate the efficacy of CDU for detection of the perforators to be used in the design of the SDMC flap. Methods: Twenty-two healthy volunteers (42 hands) were examined using both CDU and HADF. All locations identified as the perforators of the SDMA by the two examinations were mapped respectively. Results: The total perforator arteries detected with CDU in all hands were 111 branches, 49 branches of which could not be identified with HADF. The average number of perforators of the SDMA per hand found with CDU was 2.8 branches, while that for HADF was only 1.8 branches. The detection rates of the cutaneous perforators of the SDMA by CDU were 100% in the proximal onethird of the second metacarpal and 95% in the distal one-fourth of the second metacarpal. Conclusion: This study demonstrated the superiority of CDU compared with HADF for detection of the perforators of the SDMA. The CDU examination could easily identify the locations of the cutaneous perforators and help in the useful assessment of vascularity for the SDMC flap.

[1][2][3][4][5][6][7] Diferentes series clínicas muestran su utilidad para la cobertura de defectos complejos, con tasas de complicaciones que oscilan entre 0%-17%, 1-3 siendo la mayoría de ella secundarias a la congestión venosa.

Introducción Los defectos de cobertura de la mano y de los dedos de tamaño moderado son frecuentes y representan un reto para el cirujano reconstructivo. Existen varias opciones locales disponibles, y el conocimiento de la anatomía vascular de la zona nos ofrece nuevas posibilidades de cobertura. Material y métodos Se realizó un estudio anatómico en 13 extremidades de cadáveres frescos, describiendo las perforantes cutáneas en el tercio distal de la segunda arteria metacarpiana dorsal. Se presenta adicionalmente nuestra experiencia clínica inicial con el uso del colgajo perforante metacarpiano dorsal en siete casos. Resultados De forma consistente se encontró en todos los cadáveres la presencia de perforantes distales, y la ausencia de la juntura tendinae, lo que obliga a usar la cabeza del metacarpiano como límite para el punto pivote del colgajo en nuestra población, a diferencia de las descripciones anatómicas previas. En la serie de casos clínicos, el colgajo logró resolver adecuadamente todos los defectos, y se presentó solo un caso de necrosis parcial. Conclusión Luego del seguimiento de los casos clínicos reconstruidos con ese colgajo, se evidencia su versatilidad, anatomía vascular confiable y baja tasa de complicaciones, convirtiéndolo en una opción de primera línea para la cobertura de defectos digitales.

The second dorsal metacarpal artery chain-link flap: an anatomical study and a case report

Abstract: This study indicates that there are two main clusters of arterioles in the distal second dorsal metacarpal artery that can be helpful for the second dorsal metacarpal artery pedicle cutaneous chain-link perforator flaps in the repair of defects in the fingers.
