“…Normally, resting muscle blood flow is reported to be in a range between 3-8ml/min/100 g. This blood flow is increased up to 10 times when the muscle is contracted, although the blood flow was also influenced by intramuscular pressure [2,6,8]. Although the resting blood flow in this report was higher than that in other reports, our results demonstrate that blood flow in the gluteus medius muscle decreases significantly when it has been dissected (mobilised) two-thirds from its proximal or distal origins.…”

We investigated the effects of subperiosteal dissection on blood flow in the gluteal medius muscle in adult rabbits using the hydrogen washout technique. After the control blood-flow rate was determined, 8 rabbits were separated into 2 groups according to the direction of the dissection. The gluteal medius muscle was dissected from the iliac crest in the proximal-distal direction in 10 hips. In another 6 hips, the greater trochanter was osteomised and the gluteus medius muscle was dissected from the ilium in the distal-proximal direction. Dissection of the middle third of the gluteus medius muscle caused the most significant reduction in blood flow, more than 50% in both groups. This result indicates that minimising damage to the mid-portion of the gluteus medius muscle is important for reducing the incidence of post-operative complications.Résumé Nous avons examiné et étudié les effets de la dissection sous-périostale de l'écoulement sanguin dans les muscles médians fessiers de lapins adultes en utilisant la technique de lavage total à l'hydrogéne. Aprés le contrôle de la proportion de l'écoulement sanguin, les lapins furent séparés en deux groupes selon l'objectif de la dissection. Dans le premier groupe, les muscles médians fessiers furent disséqués dans 10 hanches à partir de la crête iliaque dans la direction proximale-distale. Dans le second groupe de 6 autres hanches, le grand trochanteur fut osté-otomisé, et le muscle moyen fessier fut disséqué à partir de l'ilium dans la direction distale-proximale. La dissection du tiers intermédiaire du muscle moyen fessier a provoqué la diminution la plus significative dans l'écoule-ment sanguin, soit plus de 50% pour les deux groupes. Ce résultat indique qu'une minimisation des lésions à la partie médiane du muscle moyen fessier est importante pour la réduction des complications post-opératoires.

“…Still, several studies have shown little bene®t from employing a vascular delay procedure 55,56 . Electrical stimulation may also have an impact on muscle blood¯ow; stimulation of canine gracilis at a frequency of 5 Hz has been shown to increase both intramuscular pressure and total blood¯ow, while stimulation at 100 Hz produced a reduction in total blood¯ow and consequently ischaemia 57 . It is unclear from the human studies performed so far whether early electrical stimulation results in ischaemia of the gracilis muscle.…”

Magnetic resonance imaging detection of vascular occlusion of a pedicled muscle flap

Contrast-enhanced magnetic resonance imaging (MRI) can be a highly sensitive monitor of tissue blood perfusion. This technique has been used to assess blood flow through liver, kidney, and certain tumors, but has not been widely applied to the study of skeletal muscle circulation. In our study, we used a novel scanning software to obtain contrast-enhanced T2*-weighted gradient echo MRI images of pedicled quadriceps muscle flaps in rabbits in order to study images of arterial, venous, and arterio-venous occlusion. We administered an intravenous bolus of gadoteridol contrast agent at the initiation of scanning, which produces a decrease in T2*-signal and improves the sensitivity of measuring blood perfusion. Within 30 seconds of MRI scanning, control flaps with intact pedicles exhibited a rapid decrease in T2*-signal intensity, indicating adequate perfusion of blood through muscle tissue; however, occluded pedicled flaps showed no significant change in signal intensity, indicating lack of blood perfusion. Differences in signal intensities as measured by MRI between occluded and control flaps were statistically significant (P < 0.05). Selective vascular occlusion of either artery alone, or both artery and vein were detected within 15 minutes, whereas selective venous occlusion could be detected after 2 hours. We conclude that MRI has the ability to assess skeletal muscle perfusion, and is capable of noninvasively evaluating a cross-section of tissue in both superficial and buried flaps. MRI, therefore, may have the potential for evaluating perfusion in muscle flaps (including buried flaps), and other disorders of muscle circulation such as compartment syndrome.
