“…If decreased pressures are seen with near-circumferential sponge configurations in vivo, perfusion and edema could then be measured distal to the sponge. This can be accomplished via angiography [11,13,14,19], thermal imaging [20], and/or volume measurements [21,22].…”

BackgroundNegative pressure wound therapy (NPWT) and closed incisional negative pressure wound therapy (ciNPWT) have been shown to promote the healing of acute and chronic wounds. Despite the growth in their usage, the mechanism by which they promote healing is not fully understood. Several studies have shown that NPWT results in a combination of microdeformation and macrodeformation, which may promote wound recovery. The macrodeformation forces have raised concerns about circumferential NPWT compressing the extremity and decreasing perfusion distal to the NPWT. The literature on circumferential NPWT is mixed, with some studies showing increased perfusion, while others have shown decreased perfusion. We hypothesized that a near-circumferential ciNPWT dressing applied over intact skin would provide a "lift-off" force rather than a compressive force. We also theorized that as the sponge contracts under negative pressure while in a near-circumferential setting, the dressing will pull on the surrounding skin and tissue, leading to a decrease in the pressure of the extremity. This could potentially translate to improved venous and lymphatic return, increasing perfusion to the tissue beneath the sponge as well as distal to the sponge. MethodsThis study consisted of three separate experiments. The first experiment measured the width and length of a ciNPWT dressing at various negative pressures. The second experiment utilized an in vitro model consisting of an elastic ball and tubing to examine the effects that circumferential and near-circumferential ciNPWT dressings may have on extremity pressure. Varying lengths of ciNPWT dressings were applied to the ball, ranging from 25% circumferential to 100% circumferential. The pressure within the ball was monitored as varying lengths of circumferential dressings were applied at various negative pressures. The third experiment utilized the same model as the second experiment but with a 66% circumferential dressing and various baseline ball pressures to see how extremity pressure may impact the ability of the ciNPWT dressing to alter extremity pressure. ResultsThe first experiment demonstrated that a ciNPWT dressing decreased in length and width in a linear fashion as negative pressure was applied. The second experiment revealed that both fully circumferential and nearcircumferential dressings resulted in a decrease in the pressure of the elastic ball at lower levels of suction. The greatest decrease in ball pressure was noted with the 66% near-circumferential dressing. With greater suction, however, the pressure within the ball was noted to increase above baseline. The third experiment illustrated that as the baseline pressure of a ball was increased, the dressing had less of an ability to change the pressure of the ball. ConclusionsThese results suggest that near-circumferential and circumferential ciNPWT systems may decrease the pressure of an extremity at certain negative pressures and that compression may be less likely to occur when used on a higher-pressure extremity.

“…9 Other techniques using stereophotogrammetry and infrared structured light depth sensors from XBOX Kinect ™ (Microsoft Corporation, Redmond, WA) have also been reported. [10][11][12][13] However, these techniques are limited by large hardware requirements and/or limited accuracy, and this has prevented their widespread use. Recently, LymphaTech, Inc. (Atlanta, GA) developed a novel lymphedema measuring and monitoring tool that uses a 3D infrared depth sensor integrated into a computer tablet with custom software.…”

The World Health Organization's Global Program to Eliminate Lymphatic Filariasis (LF) has reduced LF transmission worldwide, but millions remain affected by filarial lymphedema. Tools for clinically monitoring lymphedema in developing nations are limited. We tested a novel, portable, infrared three-dimensional imaging system (3DIS) against water displacement (WD) and tape measurement of limb circumference (TMLC) among patients with filarial leg lymphedema in Galle, Sri Lanka. Outcomes were accuracy and reproducibility of imaging system measurements. In parallel, we also tested the reproducibility of skin thickness ultrasound (STU) measurements. We examined 52 patients (104 limbs) with lymphedema of stages 0-6 ( = 28, 19, 20, 21, 2, 4, and 10, respectively). 3DIS measurements correlated nearly perfectly with WD ( = 0.9945) and TMLC values ( > 0.9801). The median time required to acquire imaging system measurements for both legs was 2.1 minutes, compared with 17, 7, and 29 minutes, respectively, for WD, TMLC, and STU. Median interexaminer coefficients of variation (CVs) for volume measurements were 1.1% (interquartile range [IQR] 0.5-2.1%) for WD and 1.7% (IQR 1.2-2.4%) for the 3DIS. CVs for circumference measurements were 1.4% (IQR 0.8-2.4%) by TMLC and 1.3% (0.8-1.9%) by 3DIS. Median interexaminer CV for STU was 13.7% (IQR 8.5-21.3%). The portable imaging system noninvasively provided accurate and reproducible limb volume and circumference measurements in approximately 2 minutes per patient. This portable technology has the potential to greatly improve assessment and monitoring of lymphedema in the clinic and in the field.

“…3D depth-sensing imaging has been established as a novel tool to screen for BCRL (75)(76)(77)(78). One method of 3D imaging, stereophotogrammetry, uses a 5-pod setup of 15 cameras to capture visual information from the entire arm, capturing the lower and upper arm separately (75). In a 2016 study by Hameeteman et al, 3D stereophotogrammetry was confirmed to be a diagnostically valid and reliable method of screening for BCRL [ICC: 0.997 (95% CI: 0.992-0.999), P<0.001) (75).…”

Breast cancer-related lymphedema (BCRL) is a negative sequela of breast cancer (BC) caused by trauma to the lymphatic system during surgery or radiation to the axillary lymph nodes. BCRL affects approximately one in five patients treated for BC, and patients are at a lifelong risk for BCRL after treatment. Early diagnosis of BCRL may prevent its progression and reduce negative effects on quality of life, necessitating comprehensive prospective screening. This paper provides an overview of technology that may be used as part of a BCRL screening program, including objective measures such as perometry, bioimpedance spectroscopy, tissue tonometry, and three-dimensional optical imaging. Furthermore, this paper comprehensively reviews the technology incorporated into the established prospective screening program at Massachusetts General Hospital. Our prospective screening program consists of longitudinal measurements via perometry, symptoms assessment, and clinical examination by a certified lymphedema therapist (CLT) as needed. Discussion about use of perometry within the screening program and incorporation of arm volume measurements into equations to determine change over time and accurate diagnosis is included [relative volume change (RVC) and weight-adjusted change (WAC) equations]. Use of technology throughout the program is discussed, including a HIPPA-compliant online research database, the patient's electronic medical record, and incorporation of BCRL-related symptoms [BC and lymphedema symptom experience index (BCLE-SEI) survey]. Ultimately, both subjective and objective data are usedto inform BCRL diagnosis and treatment by the CLT. In conclusion, the role of technology in facilitating BCRL screening is indispensable, and the continued development of objective assessment methods that are not only reliable and valid, but also cost-effective and portable will help establish BCRL screening as the standard of care for patients treated for BC.
