“…The LTA and the TAA are readily accessible for analysis at that time by several methods, including visual inspection and digital palpation by the surgeon, use of the Doppler, intra¬ venous fluorescein injection, thermography, and other means. 11 If circulation through the TAA-PB is poor or nonexistent, the flap should be pedicled on both the LTA and the TAA. This is done by dividing the transverse fibers of the PMM only, and leaving intact the horizontal fibers in the upper part of the muscle.…”

\s=b\In a series of 43 pectoralis major myocutaneous flaps (PMMF), five (12%) developed partial or total necrosis. The cause of necrosis was speculative in each case. To evaluate the problem, we studied the vascular supply to the PMMF, specifically, the lateral thoracic artery (LTA) and the pectoral branch of the thoracoacromial artery (TAA-PB). Ten aortic arch angiograms and 35 cadaver dissections were analyzed. The LTA and TAA-PB provided pedicles of comparable size in most cases, and in several the LTA was significantly larger than the TAA-PB. In one angiogram the TAA-PB was totally occluded, probably by atheromatous plaque. Peripheral vascular disease can affect myocutaneous flaps. We postulate that the LTA can nourish the PMMF by itself and sustain flaps that might otherwise develop necrosis.

Σε 2 ομάδες (Α και Β) των 12 ζώων (γάτες φυλής Κοινής Ευρωπαϊκής) δημιουργήθηκαν στα οπίσθια άκρα των ζώων σύνθετα ελλείμματα στην εσωτερική επιφάνεια της κνήμης. Για την κάλυψη των ελλειμάτων αυτών, στην ομάδα Α, χρησιμοποιήθηκε ολόκληρος ο ημιτενοντώδης μυς ως μυοδερματικός κρημνός, ενώ, στην ομάδα Β ο μυς χρησιμοποιήθηκε μετά από επιμήκη διαχωρισμό των μυϊκών ινών του . Στα ετερόπλευρα άκρα των ζώων τα σύνθετα ελλείμματα που δημιουργήθηκαν (τραύματα μάρτυρες), επουλώθηκαν κατά δεύτερο σκοπό. Η μετεγχειρητική αξιολόγηση των κρημνών και των τραυμάτων μαρτύρων γινόταν με κλινική βαθμολογία, πλανιμετρία, υπολογιστική τομογραφική αγγειογραφία και ιστοπαθολογική εξέταση των μυών.

\s=b\Quantification of tissue sodium fluorescein delivery was used to monitor neurovascular island flaps subjected to various manipulations of the vascular pedicle. In 20 anesthetized rats, inferior epigastric neurovascular island flaps were studied during transient arterial or venous occlusion and presumed vascular spasm. During clamping, there was no substantial fluorescein uptake by the flaps. Reinjection of fluorescein after removal of the clamps resulted in adequate fluorescein uptake and elimination in those flaps that remained viable. Three of the flaps with presumed vascular spasm eventually evidenced an increase in fluorescence with subsequent injections and remained viable; one flap did not show adequate fluorescence after any of the four injections and subsequently necrosed. It is concluded that documentation of tissue fluorescein delivery following serial injections of dye permits accurate monitoring of the functional status of the vascular pedicle at close-time intervals during the critical hours immediately after flap construction.
