Volumetric Analysis of a Novel Chimeric Gracilis and Profunda Artery Perforator Flap.

BACKGROUND: The presence of a chimeric gracilis and profunda artery perforator (PAP) flap with a common arterial pedicle has been demonstrated on computed tomography angiography in up to 59% of patients and confirmed in a cadaveric model. Already utilized for head and neck reconstruction by Heredero et al, this novel flap could provide more volume than either flap alone which is advantageous, particularly in patients with sizable defects. The purpose of this study was to determine the average tissue volume that can be utilized from this chimeric flap. METHODS: CT Angiogram imaging studies exhibiting chimeric flap anatomy were reviewed over a 7-year period at a single institution utilizing Visage Version 7.1, a radiology picture archiving and communication system. This software was used to trace the flap pedicles and to capture estimated soft tissue volumes of each respective flap. RESULTS: A total of 31 patients, consisting of 52 lower extremity gracilis and PAP chimeric flaps, underwent tissue volume analysis. The average total volume of soft tissue supplied by the gracilis flap was found to be 70.21 cm3 (standard deviation [SD] = 26.99). The average volume of the PAP flap was 31.73 cm3 (SD = 26.12). The average total volume captured by the chimeric gracilis and PAP flap was 101.94 cm3 (SD = 62.40). CONCLUSION: The potential soft tissue volume that can be harvested from a chimeric gracilis and PAP flap is significantly greater than solitary gracilis or PAP flaps. This chimeric flap may serve as a viable and advantageous reconstructive option for patients requiring large volume soft tissue coverage, particularly if other sizable options are not available.

Analysis of online materials regarding DIEP and TRAM flap autologous breast reconstruction.

Online resources have become a mainstay for health information, and it is vital that such resources maintain accessible literacy levels to empower informed decision making. Previous studies have shown that the online resources regarding post-mastectomy breast reconstruction are of low readability; however, none have evaluated specific online resources regarding the most common procedures within autologous breast reconstruction, limiting analysis to the results of generic searches. This study sought to discover the readability of online, patient-directed resources regarding the Deep Inferior Epigastric Perforator (DIEP) and Transverse Rectus Abdominis Muscle (TRAM) flaps, the most utilized autologous flaps in breast reconstruction, using health literacy analysis. We hypothesized that the online materials regarding DIEP and TRAM flaps would yield literacy scores above the 6th-grade reading level, as recommended by the American Medical Association, despite previous literature and readability recommendations. Google searches for "DIEP breast reconstruction" and "TRAM breast reconstruction" were conducted. All patient-directed, non-sponsored websites found within the first three pages of the search underwent analysis using a variety of readability formulae. Both DIEP and TRAM resources were well above the 6th-grade reading level according to every metric used, and there was no significant difference in the reading level between the two procedures. Based on these results, significant work was needed to simplify the online resources to be more understandable for patients; these authors propose one method for such. In addition, the low readability of online resources suggests added emphasis on the need for surgeons to ensure that patients understand the medical information discussed during the presurgical consultations.

Comprehensive Management of Pressure Injury: A Review.

Pressure injuries (PIs) are a spectrum of localized tissue destruction that develops most often at a bony prominence. PIs are the result of a combination of extrinsic (eg, pressure, shear, friction, and moisture) and intrinsic (nutritional status, spasticity, decreased sensation, and vascular disease) factors. Given their complex etiology, management of PIs requires a multidisciplinary approach from a team of health care professionals. After addressing both extrinsic and intrinsic factors, local wound care is generally recommended for stages 1 to 2 PIs and surgical intervention for stages 3 to 4.

Autologous Cell Harvesting System as Adjunct for Soft-tissue Reconstruction of Necrotizing Soft Tissue Infection.

Necrotizing soft tissue infections (NSTIs) cause rapidly progressing destruction of skin and soft tissue, leaving large soft tissue defects and necessitating complex reconstruction. RECELL, an autologous cell harvesting device, provides a regenerative epidermal suspension (RES) from a small split-thickness skin biopsy for the substitution of (or in addition to) split-thickness skin grafting (STSG). We present a case of a 56-year-old man with extensive NSTI managed by serial debridement, leading to a degloving injury to the right upper extremity, axilla, flank and back, which was later reconstructed using RES application in conjunction with STSG and Integra placement. At his 2-week hospital follow-up, the patient was healing well with limited right upper extremity range of motion, but continued improvement seen with physical and occupational therapy. Due to the patient's significant soft tissue defect, a unique reconstructive plan was required using both Integra and RECELL in conjunction with STSG. RECELL, in conjunction with STSG, should be considered for the treatment of significant soft tissue defects such as those found in NSTI.
