带浅静脉干局部皮瓣的基础与临床   总被引:2,自引:0,他引:2  
静脉在顺行皮瓣中的作用是不言而喻的 ,但带浅静脉干的逆行皮瓣或逆行岛状皮瓣静脉的作用仍存在争议 ,主要有二点 :一是静脉有瓣膜存在 ,静脉血如何回流 ;二是静脉血倒灌影响皮瓣的存活。目前在这方面的研究较少 ,近几年来 ,第一军医大学珠江医院通过对主要浅静脉干的组织解剖学研究 ;浅静脉干的血流动力学以及临床应用方面的研究证实 :浅静脉干存在自身的滋养血管 ,其与静脉干本身及其周围组织存在广泛的联系 ,对皮瓣的供血及引流具有重要作用 ;静脉血不会倒灌 ,带浅静脉干更有助于静脉血引流 ;临床应用也证实带浅静脉干皮瓣较不带浅静脉干的皮瓣成活率要高。目前该研究比较粗浅 ,还有许多因素值得进一步探讨  相似文献

逆行皮瓣中浅静脉干的形态学与血流动力学观察   总被引:1,自引:0,他引:1  
目的:通过对浅静脉干的形态学和血流动力学观察,探索浅静脉干促进逆行皮瓣静脉回流的机理,进一步指导带浅静脉千逆行皮瓣的临床应用。方法:用小鼠耳制成带浅静脉干的逆行皮瓣模型共48例,每个皮瓣内只有一条浅静脉干,用微循环观察仪对浅静脉干进行形态学和血流动力学观察。结果:根据形态可将逆行皮瓣中的浅静脉千分为3种类型:“I”形,“Y”形和树枝形,各种类型的浅静脉干都是皮瓣静脉逆向回流的主要通道,如果在蒂部将浅静脉干闭塞,皮瓣的静脉回流基本停滞。结论:浅静脉千的存在有助于逆行皮瓣的静脉逆向回流,并在回流中起类似“枢纽”的重要作用,临床应尽量选用“I”形浅静脉干。  相似文献

Ear helix flap for reconstruction of total loss of the upper eyelid.   总被引:1,自引:0,他引:1  
We present a patient with a recurrent carcinoma of the right upper eyelid who underwent resection of the subtotal upper eyelid resulting in a full-thickness defect. The eyelid was reconstructed with advanced conjunctival lining and an ascending helix chondrocutaneous flap from the right auricle. This flap was nourished with a reverse flow of the frontal branch of the superficial temporal vessels. A superficial temporal vein of the flap was anastomosed to the zygomaticofacial branch of the superficial temporal vein at the lateral canthal region to ensure adequate drainage. The flap survived without any congestion. An ascending helix flap is the best candidate for total loss of the upper eyelid.  相似文献

Microsurgical technique allows successful transfer of an auricular flap in a one-stage procedure, using the root of the helix. Although a free composite auricular flap with the superficial temporal artery pedicle provides a good solution to repair nasal defects, its vascular pedicle is so limited that a vein graft from other area of the body is usually needed to reach the recipient site, leaving an unpleasant scar on the donor site. The authors present a reversed superficial temporal artery auricular free flap for alar reconstruction by microsurgical transfer. This technique has been performed on four patients with posttraumatic alar defects. In three patients, the reversed superficial temporal vessels of the flap were anastomosed directly with the recipient facial vessels in the nasolabial fold. In one patient, the reversed superficial temporal artery of the flap was anastomosed with the facial artery as above, its accompanying vein to the proximal stem of the superficial temporal vein by a graft taken from the excess length of the reversed superficial temporal artery pedicle because a suitable vein was not found for microvascular anastomosis in the nasolabial area. In these four patients, the size of the flap was 2.5 x 2.0-4.0 x 2.5 cm, the length of the vascular pedicle is 5-8 cm, average 6.5 cm. The reversed superficial temporal artery auricular flap offers a long vascular pedicle of the auricular free flap for microvascular anastomosis in the reconstruction of the ala of nose, delivers a good solution to the problem of the vascular pedicle shortage of the proximal superficial artery auricular flap. There is no need of vein graft from other parts of the body because the superficial temporal vessels on the temple provide not only the flap pedicle but also a source of vessel grafts. This technique may have even wider applications in other facial cutaneous defect.  相似文献

The transverse rectus abdominis musculocutaneous (TRAM) flap has been widely used for reconstruction of the breast. Partial loss of the flap is still a problem, however, and venous congestion may cause partial necrosis of the flap. There are few studies of the venous anatomy of the TRAM flap that compares with that of the arterial system, so the aim of this study was to investigate the venous anatomy of the TRAM flap and assess its drainage pathway using venography. A mixture of barium and gelatin were injected through the cutaneous veins such as the superficial inferior epigastric vein (SIEV), the superficial circumflex iliac vein (SCIV), or the perforating branch of the deep inferior epigastric vein (DIEV) in 11 hemiTRAM flaps. Venograms of TRAM flaps were taken, and the venous anatomy evaluated. The study showed that it consisted of the dominant superficial venous system, the SIEV and SCIV, and the secondary deep venous system, and the perforating vein of DIEV (DIEV perforator). In addition, we saw the large communicating veins between the SIEV and DIEV perforator near the umbilicus. We think that these communicating veins, which are considered as the DIEV perforators between the superficial and deep venous system, are an important venous drainage pathway after the TRAM flap has been raised.  相似文献

Introduction  Reconstruction forms the primary tenet in plastic surgery. Venous flaps are a known option but the survival is limited. Arterialization of venous flap can enhance its survival. While various techniques of arterialization of venous flaps are described, there are very few studies comparing them. Material and methods  The current study was conducted among 34 rats weighing 160 to 200 grams. The rats were divided into four groups. Group I—islanded epigastric flap was raised with superficial caudal epigastric vessels as pedicle. Group II—arterialized flow through venous flap was raised with superficial caudal epigastric vein (SCEV) as afferent and lateral thoracic vein as drainage vein. Side-to-side anastomosis was done between femoral artery and vein, lateral to the origin of superficial caudal epigastric artery. Group III—after raising the flap, as in group II, femoral vein was ligated proximal to superficial caudal epigastric vessels. Group IV—an arterialized flow through venous flap was raised with superficial caudal epigastric vein as afferent and lateral thoracic vein as drainage vein. End-to-side anastomosis was done between femoral artery and superficial caudal epigastric vein. Animals that died before completion of the study were excluded. The color changes of flaps were noted. Flap survival was expressed as a percentage of the total flap surface area. The patency of anastomosis was seen on postoperative day 5. Results  There was no total flap failure. On statical analysis, the flap survival area on day 5 between Group I and Group IV was not significant ( p value 0.431). The survival area in Group I (78.85 ± 10.54%) was comparable to Group IV (65.71 ± 20.70%). Group II and III had poor results as compared with Group I. In four rats, thrombosis of arteriovenous anastomosis was noted with flap survival area of 30 to 33%. Conclusion  It was noted that epigastric venous flaps with end-to-side anastomosis between femoral artery and superficial caudal epigastric vein (group IV) have survival area comparable to islanded flaps.  相似文献

Venous congestion in a free TRAM or DIEP flap when the main pedicle is still patent (both the artery and the vein) is an occasional dire situation. Here, we describe ways of salvaging the free TRAM or DIEP flap from imminent loss. In the last 4 years, we have had three patients who developed venous congestion after the use of the TRAM or DIEP flap for breast reconstruction. This was detected as late as the third postoperative day in our first patient. On exploration, patent arterial and venous anastomoses were found. Fortunately, the opposite pedicle had been dissected and preserved with the flap. The patent congested vein in this pedicle was anastomosed to the cephalic vein using an interpositional vein graft, relieving the congestion. In the other two patients congestion was detected earlier and relieved using the superficial inferior epigastric vein. It has been our policy to dissect a length of the opposite pedicle and/or preserve a length of the superficial inferior epigastric vein or the superficial circumflex iliac vein. These can then be used to augment venous drainage if inadequacy is noted at the end of the operation or during the postoperative period.  相似文献

The abdominal skin of 135 rats was fashioned to be normal on venous flap for investigating the difference in quality of the two. For normal flap, the right superficial epigastric artery was used to serve as the nourishing vessel and the left superficial epigastric vein the draining one. For venous flap, the right superficial epigastric vein was made to be the nourishing vessel and the left superficial epigastric vein the draining one. The flap in group I was fed with blood from the distal end of the femoral vein; the flap in group II was supplied with blood from the distal end of the femoral artery; and the flap in group III was nourished with blood from the femoral artery. It demonstrated that the venous flaps in group I were better in quality than the normal flaps in terms of survival rate, elasticity and size of ulcer. However, the results in group II and group III were quite different. As for clinical use, it would be all right to cover small wound with venous flap; while repairing large defect, particularly in exposed part or area near a joint, normal flap should be of the choice.  相似文献
