This study was carried out to observe the isolated effects of pedicle torsion on island skin flaps, without further damaging the pedicle. Twelve adult male Sprague-Dawley rats, weighting 240 to 300 gr, were used, and hexagonal flaps with edges measuring 1.5 cm and pedicles measuring 1 cm in length were raised in the inguinal region. The animals were divided into two groups. In Group A, flaps were re-sutured to the donor beds without any rotation. In Group B, flaps were rotated 360 degrees, applying the same degree of torsion to their pedicles before re-suturing. After 7 days, the percentage of surviving skin areas of the flaps was determined by planimetry, and transverse sections of the flaps and pedicles were taken and evaluated in terms of signs of arterial or venous insufficiency. Statistically significant differences between the groups were determined by analyses using the multiple comparisons test. Pedicle torsion in Group B did not affect flap viability, both macroscopically and microscopically. The presented study shows that 360-degree torsion applied to the pedicle of the flap in this model had no effect on flap viability. 相似文献

This study was performed to investigate the venous drainage in reverse island groin flaps in a rat model. Two groups of 10 rats were studied. All rats of group A had a groin reverse flap with a complete pedicle (artery and venae comitantes). In rats of group B, an arterial groin reverse flap (artery without venae comitantes) was performed. For the two groups, the perivascular tissue was excised. Nine flaps in the group A and seven flaps in the group B, survived without partial or complete necrosis. Microscopic examination showed venous dilatation in the two groups. There was no significant difference between the two groups. These results confirm that venous drainage of the arterial reverse flow flap without venae comitantes is performed by venae arteriosa. However, venae comitantes probably ensure venous drainage when they are respected. 相似文献

Stereomicroscopy as a diagnostic aid in evaluating the viability of island flaps: an experimental study 总被引:1,自引:0,他引:1
This study entailed direct stereomicroscopic observations of rat abdominal island flaps and the sequence of vascular events that occurred during and after occlusion by clamping of the individual femoral vessels for varying time intervals of up to 16 hours. The vascular changes and the status of the circulation in the flap vasculature, including the timing of complete hemal stasis and resumption of flow, following the application and subsequent release of the vessel clamp were observed and correlated with flap viability and behavior. This study also included a grading system of the vascular changes observed under a stereomicroscope. From these findings, it is suggested that in vivo stereomicroscopy may serve as a new and simple clinical tool for the early diagnosis of thrombosis at the site of microvascular anastomosis of a free flap transfer and may define time limits during which the anastomosis can be successfully corrected and the flap salvaged. 相似文献

Prefabrication provides a new method for creating donor sites which are not limited by natural vascular territories. There are several methods for prefabrication, and these include implantation of greater omentum, blood vessels or muscle flaps. Based on the concept that an arterio-venous (A-V) shunt results in sufficient neovascularisation to support a free flap, we used a rabbit model to investigate the characteristics of these flaps. Prefabrication of an abdominal wall donor site was performed using the left epigastric vein in 20 male New Zealand white rabbits. An 8 x 10 cm skin flap was elevated 10 days after prefabrication, either as an island or a free flap. Survival of the skin flaps exceeded 93% and was independent of position of the vascular pedicle, direction of blood flow, or nature of the flap (island or free flap). Angiograms showed a very rich neovascularisation within the prefabricated flap. 相似文献

Background: The main purpose of this study was to assess the effects of ozone gas on the viability of flaps for reconstruction and to determine the optimum application method. The antioxidant, immunomodulatory, and reperfusion effects of ozone gas have been previously assessed, and successful results have been reported. However, only one study has investigated the effect of ozone gas on flap viability. In the present study, it was hypothesised that the antioxidant and reperfusion effects of ozone gas would enhance flap viability.Methods: Forty female Wistar rats were randomly divided into four groups of 10 rats each. A cranial-based, 3?×?11?cm modified McFarlane flap including the panniculus carnosus was raised from the dorsum of a rat and re-sutured to its own bed using 3/0 sharp propylene. Group 1 (n?=?10): no pharmacological agent was used after the operation. Group 2 (n?=?10): vegetable (olive) oil group; vegetable-oil-impregnated gauze was used as a dressing for 7 days. Group 3 (n?=?10): Vegetable (olive) oil with ozone peroxide group; vegetable oil with ozone peroxide-impregnated gauze was used as a dressing for 7 days. Group 4 (n?=?10): Hemo-ozone therapy group; hemo-ozone therapy was applied rectally once every day for 7 days. All rats were sacrificed at the end of week 1 and assessed macroscopically and histopathologically.Results: The proportion of substantive necrosis was less in group 4 than in the other three groups. Survival area ratios were better in groups 2 and 3 than in group 1; however, there was no significant difference between groups 2 and 3. No significant differences in the histopathological scores were observed among the groups.Conclusion: Ozone gas enhanced flap viability. No differences in flap viability were observed between the vegetable oil and vegetable oil with ozone peroxide groups. The greatest benefit ratios were found in the hemo-ozone therapy group. 相似文献

Prefabrication of thin transferable axial-pattern skin flaps: an experimental study in rabbits. 总被引:5,自引:0,他引:5

The arteriovenous pedicle of all known axial-pattern skin flaps enters from the deep aspect and consequently the flap must contain fat and/or muscle and be of considerable thickness. In an attempt to fabricate a thinner axial-pattern flap the femoral artery and vein of rabbits were implanted, in various vascular configurations, directly into the subdermal layer of the skin. Implantation was found to provoke an extensive outgrowth of new vessels from the implanted artery and vein, and the progress and pattern of this neovascularisation was studied by carbon gelatine perfusion and histology. Neovascularisation begins within a few days of implantation and progresses rapidly. By 8 to 12 weeks it is possible to elevate regularly a viable, large skin flap based on the implanted pedicle. 相似文献

The modern treatment of musculoskeletal malignant tumours often requires different combinations of surgery, chemotherapy, and radiotherapy. Although combination treatments have allowed reconstruction of more complex defects, the risk of complications also rises. In clinical series the complication rate is influenced by the characteristics of the defect and the quality of the radiation used. The flap survival is high, but the overall complication rate is more than 25%. In this study we looked at the healing of microvascular free skin flaps exposed to postoperative irradiation in a rat model. Epigastric microvascular free skin flap were exposed to a single dose of 20 Gy radiation one week postoperatively (n = 8). A comparison was made with free epigastric skin flaps without postoperative radiation (n = 8). The healing was assessed histologically at four weeks and by measuring the tensile strength of the wound. Biochemical total nitrogen and hydroxyproline contents were also measured. Results showed that histologically the interfaces healed similarly with only minimal histomorphological changes. Neither the mechanical strength of the healing interface nor the biochemical markers altered significantly. Postoperative irradiation with a single dose of 20 Gy does not affect the survival of free skin flaps in rats. In the future the model described could be used to study the effects of combination therapy of surgery, radiotherapy, and chemotherapy more closely to find the optimal control of malignancies with limited damage to treated tissue. 相似文献

目的 以新西兰大白兔隐动静脉逆行岛状皮瓣为实验模型,探讨结扎血管蒂伴行静脉干对逆行岛状皮瓣存活的影响.方法 将10只新西兰大白兔两侧后肢左右随机分为2组,每组10个皮瓣,进行同体对照.建立隐动静脉逆行岛状皮瓣实验模型(面积3 cm×3 cm,血管蒂长4 cm,血管蒂周围保留1 cm宽筋膜).对照组:血管蒂部不做任何处理;实验组:在放大10倍手术显微镜视下于血管蒂的两端分别结扎伴行静脉干,使2根伴行静脉干完全闭塞.术后每天观察皮瓣颜色、肿胀情况.术后1周测皮瓣成活率,并切取血管蒂进行组织学观察.结果 术后两组皮瓣均有较明显的肿胀,实验组皮瓣肿胀更为明显.两组皮瓣平均成活率比较,对照组为(92.7±12.1)%,实验组为(46.8±38.3)%,差异有统计学意义(t=3.61,P<0.01).两组皮瓣蒂部均可见扩张的微血管,高度肿胀导致坏死的皮瓣,在其蒂部扩张的微血管内可见血栓形成.结论 血管蒂的伴行静脉结扎使皮瓣更易发生静脉危象,导致皮瓣坏死.微血管内血栓形成可能是导致皮瓣静脉回流障碍的又一重要因素.Abstract: Objective To evaluate the effect of ligating venae commutantes in the pedicle on the survival of reverse-flow island flaps. Methods Ten New Zealand rabbits were used. Reverse flow island flap based on the saphenous artery and vein was created on both hind limbs,with a total of 20 flaps. The size of the flap was 3 cm×3 cm with a 4 cm long vascular pedicle containing 1 cm strip of connective tissue. These flaps were randomly divided into 2 groups of 10 flaps each. In group Ⅰ,the vascular pedicle (1 saphenous artery and 2 venae commutantes) was raised and its sheath was not disturbed,maintaining communicating and collateral branches intact. In group Ⅱ,the 2 venae commutantes were ligated with 8-0 suture at both ends of the pedicle under 10X microscope and the connective tissue was maintained intact. The color and congestion of flaps were observed daily. Flap survival rate was measured after one week. The vascular pedicle was harvested and observed histologically. Results The flaps began to appear obviously swelling after blood oozing stopped. The extent of swelling was more severe in group Ⅱ than in group Ⅰ. Flap survival rate of group Ⅰ (92.7±12.1)% was significantly higher than that of group Ⅱ (46.8±38.3)% (t=3.61,P<0.01). Histological examination revealed lots of dilated venules in the vascular pedicle. The amount of dilated venules in group Ⅱ was more than that in group Ⅰ. Lots of thrombi could be seen in the dilated venules in the pedicle of completely or partially necrotic flaps. Conclusion Venous crisis takes place more easily in flaps without venae commutantes,resulting in flap necrosis. The venous thrombosis may be the other important influencing factor for necrosis of reverse-flow flaps. 相似文献

Comparison of venous drainage in reverse-flow island flaps: an experimental study of the rabbit saphenous fasciocutaneous flap 总被引:2,自引:0,他引:2
The mechanism of venous drainage in reverse-flow island flaps was investigated using the saphenous fasciocutaneous flap in New Zealand White rabbits. Ten animals were allocated into two groups of 10 flaps. In group I (left limb), the distal vascular pedicle (one saphenous artery and two venae comitantes) was not disturbed, maintaining the communicating and collateral branches intact. In group II (right limb), it was separated microsurgically from each other for 3 cm. Intravenous pressure was measured at 5, 15, 30, and 60 minutes after tourniquet release. The values of group II at 30 and 60 minutes were significantly lower (p<0.01) than those of group I. Ten days after flap elevation, the mean survival area of group I (95%) and group II (100%) was not significantly different. Histological examination of the vascular pedicle showed the saphenous veins in group II were more dilated than those of group I. These findings suggest that venous retrograde return in reverse-flow island flaps can be achieved more easily through a "direct incompetent valves route" than through a "circuitous communicating and collateral bypass route." 相似文献

Verapamil improves survival of rat hyperemic island skin flaps 总被引:1,自引:0,他引:1
Inability to maintain cellular calcium homeostasis is a critical factor in the pathogenesis of cellular ischemic injury and may mediate oxygen radical release in the reperfusion period. We assessed the effect of the selective calcium channel blocker verapamil on the performance of rat hyperemic island skin flaps. Pretreatment with verapamil markedly improved survival of skin flaps after 6 hours of venous cross-clamping compared with animals receiving placebo only (99% vs 53.3%; p less than 0.01). Verapamil also prevented the formation of lipid peroxidation products and the depletion of the endogenous antioxidant glutathione, suggesting that the beneficial effect of verapamil is the result of protection against oxygen radical injury. After 12 hours of venous cross-clamping, verapamil did not improve survival of skin flaps despite protection against lipid peroxidation. Oxygen radical release is therefore a crucial event in the pathogenesis of skin flap necrosis after short-term ischemia but is of less significance in long-term ischemia. 相似文献

The value of neurovascular island skin flap transfers for digit tip surfacing has been evaluated in 13 patients. A computer assisted sensory evaluation was carried out on six of the patients. All patients were satisfied with the procedure. Sensory acuity did not appear to diminish with time and sensory misreference was not a major functional problem. We suggest that the neurovascular island flap, when available, is still an excellent procedure for restoration of useful digit tip sensibility. 相似文献

The aim of this study was to apply the hypothesis of ischemic preconditioning (IP) on free skeletal muscle (rat thigh flap). Five groups of Sprague-Dawley rats (n = 6) were used. In group A (control group), standard free autologous flap transfers were performed. Flaps in groups B and C underwent 4 and 6 h, respectively, of ischemia before transfer. In groups D and E, muscle flaps were preconditioned (3 x 10 min ischemia interrupted by 10 min of reperfusion, clip applied on the dissected artery of the flap) and subjected to 4 and 6 h, respectively, of ischemia before transfer. After 48 h of reperfusion, the muscle flaps were evaluated macroscopically as well as by histological and immunohystochemical staining. In group A, the viability was 100%, whereas in groups D and E the viability was 83.3% and 100%, respectively. Groups B and C had undergone macroscopically parceled to total necrosis, further confirmed by histological findings (fragmentation and disappearance of muscle striations, combined with tissue necrosis and intravascular thrombosis). The beneficial effect of IP demonstrated in the heart, liver, and small bowel extends to skeletal muscle, which can be used in free-flap transfers, if the transfer includes a long period of predictable ischemia. 相似文献

The pathway of venous drainage in retrograde island flaps was investigated by fluorescence tracing technique using the saphenous fasciocutaneous flap in New Zealand White rabbits. Forty animals were allocated into four groups according to the different times at 30 minutes (I), 24 hours (II), 72 hours (III), and 7 days (IV) after the operation. According to the different routes to give tracer, each group was further allocated into two subgroups of the artery injection and vein injection. For each animal, one hindlimb was assigned as the experimental side, the contralateral side as control without giving tracer. The erythrocytes were separated, labeled with fluorescein isothiocyanate (FITC), detected, and injected into the artery or vein. Subsequently, the flaps were harvested 5 seconds after injection and immediately frozen, sectioned, and observed under microscope. In group I and II, the fluorescence was observed mainly around the vessel adventitia of the vein and artery and tunica intima of the artery. In group III, there was weak fluorescence observed in the lumen of vein. In group IV, fluorescence was distributed principally in the lumen of the vein. In addition, fluorescence was not observed in the saphenous nerve in group I and there was mild fluorescence in the saphenous nerve in groups II, III, and IV. These findings suggest that the venous return is through “bypass route” in earlier period. In later period, the venous retrograde return is through “bypass route” and “incompetent valves route;” however, “incompetent valves route” becomes the main route. © 2009 Wiley‐Liss, Inc.

From January 1979 to October 1986, 86 cases of soft tissue defect were repaired by skin and musculocutaneous flaps. Among them, 43 instances were free flaps and 43 instances were island flaps. Of these 86 flaps, 79 survived completely, 2 partially, and 5 failed. The sizes of the flaps ranged from 6 x 7 cm to 32 x 10 cm. In this paper, indication of operation and selection of the flaps were discussed. 相似文献
