“…25 Currently, dynamic IRT is being used preoperatively in identifying the appropriate perforator vessel to be transplanted as well as in flap monitoring after free flap transplantation, where changes in arterial or venous perfusion influence the skin temperature. 17,23,28 The sensitivities lie between 89.6 and 99.6% and specificities between 96 and 99.9%. 20 After supplying blood to the chest wall, IMA continues to the abdomen wall as the superior epigastric artery, where it anastomosises itself to the inferior epigastric artery to supply the perfusion to the abdominal wall.…”

Infrared Thermographic Imaging of Chest Wall Perfusion in Patients Undergoing Coronary Artery Bypass Grafting

Coronary artery disease represents a leading cause of death worldwide, to which the coronary artery bypass graft (CABG) is the main method of treatment in advanced multiple vessel disease. The use of the internal mammary artery (IMA) as a graft insures an improved long-term survival, but impairment of chest wall perfusion often leads to surgical site infection and increased morbidity and mortality. Infrared thermography (IRT) has established itself in the past decades as a non-invasive diagnostic technique. The applications vary from veterinary to human medicine and from head to toe. In this study we used IRT in 42 patients receiving CABG to determine the changes in skin surface temperature preoperatively, two hours, 24 h and 6 days after surgery. The results showed a significant and independent drop of surface temperature 2 h after surgery on the whole surface of the chest wall, as well as a further reduction on the left side after harvesting the IMA. The temperature returned to normal after 24 h and remained so after 6 days. The study has shown that IRT is sufficiently sensitive to demonstrate the known, subtle reduction in chest wall perfusion associated with IMA harvesting.

Background and objectivesCerebral revascularization surgery is the mainstay of treatment for moyamoya syndrome (MMS) today, and intraoperative determination of the patency of the revascularized vessel is a critical factor in the success of the procedure. Currently, major imaging modalities include intraoperative indocyanine green (ICG) videoangiography (ICG-VA), digital subtraction angiography (DSA), and vascular ultrasound Doppler. Infrared thermography is a modern imaging modality with non-contact devices for the acquisition and analysis of thermal data. We aimed to investigate the feasibility and advantages of infrared thermography in determining anastomotic patency during MMS surgery.MethodsIndocyanine green videoangiography and infrared thermography were performed simultaneously in 21 patients with MMS who underwent bypass surgery. The detection result of vessel patency was compared, and the feasibility and advantages of infrared thermography were assessed.ResultsThe patency of the anastomosis was accurately determined in 21 patients using either ICG angiography or infrared thermography. In 20 patients, the results of infrared thermography showed that the vascular anastomosis was unobstructed, and there was an agreement with the subsequent results of ICG-VA. In one patient, we suspected inadequate patency after testing the anastomosis with infrared thermography, and the results of ICG-VA evaluation of the anastomosis confirmed that there was indeed an anastomotic obstruction.ConclusionCompared with ICG-VA, infrared thermography might offer an alternative non-invasive, contrast-free option in assessing anastomosis patency compared with ICG-VA, and it is likely to become more widely used in the clinic in the near future.

“…One of the new methods for flap perfusion assessment tools is thermal imaging. It was used for preoperative planning [23], intraoperative flap perfusion assessment [24] and post-operative monitoring [25] with promising results but more research in this point is still needed for standardization of this non invasive tool.…”

Introduction: Reconstruction of complex wounds in the upper limbs is a difficult task as multiple structures, including nerves, blood vessels and tendons are arranged in a relatively small soft tissue envelope with limited options available for reconstruction. Early dtection and proper mangemnt of vascular compromise of perforator flaps is key for success of these reconstructive surgeries.Aim: Evaluating of perferator flaps to cover upper limbs wounds.Patients and Methods: Twenty-four cases were included in this study. After wound debridement, fasciocutaneous flaps nourished by perforator vessels were used for coverage in these patients. All patients were followed-up for at least 12 months.Results: Twenty-three patients were males, and one patient was female. The age ranged from 9 to 55 years. All flaps survived completely except one flap which showed partial necrosis. Within 12 hours after surgery, temporary venous congestion was observed in 2 cases. Conservative measures could resolve venous congestion with flaps' survival. Followup showed excellent contour of the flaps with stable coverage. Regional perforator flaps included in this study was radial artery perforator flaps (8 cases), ulnar artery perforator flaps (6 cases), posterior interosseous artery perforator flaps (8 cases) and lateral arm flap (one case). Conclusion:Perforator based flaps provide stable wound coverage with low cost and low morbidity rate for coverage of complex wounds in the upper limb. Careful and meticulous technique and early detection of venous congestion is critical for survival of these flaps.
