From January 1990 to December 1998, 631 consecutive single-digit replantations were reviewed retrospectively to determine the essential number of vascular anastomoses and the artery-to-vein ratio for successful finger replantation. The correlations between the number and the ratio of anastomosed vessels and the survival rate were examined according to the amputated digital levels, and all of the correlated results were compared with each other statistically. In zone I, the survival rate of the digits with a vein repaired was higher than that of digits treated with the external bleeding method. In zone II, repairing more arteries than veins led to venous congestion and resulted in a failure of replantation. Thus, the ratio of an equal or greater number of veins repaired to the arteries repaired was an important factor in successful replantation in zone II, which may be due to the large amount of arterial input relative to the small volume of venous drainage via small veins in the replanted digit. In zone III, the equal number of arteries and veins repaired was also an important factor in successful replantation. However, unlike zone II, even when more arteries were repaired than veins, venous congestion occurred rarely because the vein in this area was larger, providing sufficient venous drainage. In zone IV, repair of two veins was needed to yield good results. Because the volume of the amputated part in zone IV was larger than in other zones, it was desirable to repair both arteries, even though repairing one artery yielded good results. In conclusion, it is desirable to repair as many vessels as possible to increase the possibility of a good result. However, digital amputations and their conditions for replantation differ. Therefore, the number and ratio of vessels that need to be repaired should be modified and adjusted in each case. 相似文献

Even if good motor function returns in a replanted digit, if no useful sensation returns, the digit cannot be considered fully functional. In such cases sensory reconstruction with nerve grafts may be necessary, but it is difficult to determine the optimal time for such surgery. Therefore, we studied 37 replanted digits in which the palmar digital nerves had been severed bilaterally and anastomosed at the replantation procedure. Our findings indicate a correlation between the time at which sensation returned to the digits and the degree of two-point discrimination (2PD) that returned. In digits in which sensation returned less than four months after replantation, a 2PD of less than 15 mm returned in more than 50% of cases, but when more than four months passed before the return of sensation, a useful degree of 2PD seldom returned. We believe, therefore, that if the recovery of sensation in a replanted digit has not been satisfactory by four months after replantation, reconstructive surgery should be considered. 相似文献

Replantation of untidily amputated finger, hand, and arm: experience of 99 replantations in 66 cases
Three problems the authors think important in replantation of untidy amputations are discussed based on our 99 replantations with the success rate of 92.6% over a 4-year period. To restore circulation in this type of amputation, such techniques as transfer of blood vessels, use of a neurovascular island flap with neurovascular anastomoses at its distal margin, vein graft, and free split-skin graft directly on the anastomosed blood vessels are recommended. Recovery of tendon gliding when replanted proximally to the MP joint was reasonably good but not when replanted distally to it. Recovery of intrinsic muscles was generally poor. Protective sensation was usually regained, although occasionally accompanied by paresthesia. Amputation of single digit was found not to be an absolute indication for replantation except for the thumb. In multiple digital amputation, more important digits should be restored by amputated digits in better condition. Replantation for cosmetic improvement may be justified in such cases as unmarried young females. In infants, replantation is especially worthwhile because good functional recovery and good further growth can be expected. 相似文献

This paper reports a series of 14 cases of digital replantation in children who had had a total of 17 digits traumatically amputated. All but two digits survived, for an overall success rate of 88%. The length of follow-up was between 3 and 14 years (average 8 years). Sensory recovery of all digits was satisfactory. The mean growth rate of replanted digits relative to contralateral digits was 86%. Twelve cases had an excellent result, and one case had a good result. Digital replantation in children is recommended when feasible. 相似文献

In 34 of the 62 patients treated for complete multiple digital amputations, the severed part was not replanted in its anatomical position, but in the place of the most useful stump. This procedure is defined as transpositional digital microsurgery and refers to the transposition and replantation of any digit to another stump which plays a more significant role in the function of the hand. Twenty-eight patients had transposition of a digit, while six patients underwent thumb transposition. All except six of the transposed digits survived, while all of the thumbs survived the surgical procedure. The cosmetic appearance of the hand with a transposed digit or thumb was acceptable to the patients. Two-point discrimination was assessed to be 10–14 mm for the transposed digits, and the functional ability of the transplanted digit was comparable to digits which were replanted in their anatomical position. In conclusion, transpositional digital microsurgery remains a useful alternative for the treatment of multiple digit amputations, particularly in patients with severely damaged non-replantable amputated parts. © 1994 Wiley-Liss, Inc. 相似文献

Heterotopic or transpositional replantation of digits is technically feasible with results similar to those of conventional replantation procedures. Occasionally in multiple digital amputations not all the digits may be replanted in their correct place as a result of complex injuries proximal to the amputation zone or severe damage to important fingers. In these circumstances the amputated digits that are in the best condition as regards undamaged tissue are used for replantation. The primary priority is an optimal functional outcome and the secondary priority the cosmetic outcome. Amputated long digits will always be used to substitute for a non-replantable thumb rather than to replace a long finger. We present 13 cases of successful transpositional digit or joint replantations in traumatic amputations of more than one digit. 相似文献

PurposeThe purpose of this study was to evaluate outcomes for patients sustaining a distal fingertip amputation who underwent replantation witharteriovenous anastomosis for venous drainage over a one year period at our institution. This technique has been utilized when insufficient veins are identified in the amputated part for standard veno-venous anastomosis.MethodsA retrospective study was performed on patients presenting from 2013 to 2014. Guillotine, crush, and avulsion/degloving injuries were included if they underwent fingertip (Tamai Zone I) replantation with arterial anastomosis for vascular inflow and arteriovenous anastomosis for venous drainage. The cases were further classified as Ishikawa subzone I and subzone II.ResultsArteriovenous anastomosis for venous drainage during replantation was used in 45 digits in 35 patients. 41 of the 45 digits underwent successful replantation using this technique (91%). The mean active ROM in the DIP joint of the fingers and in the IP joint of thumbs was 65° and 57°, respectively. Sensory evaluation demonstrated a mean of 6.9 mm s2PD in digits where the digital nerves could be repaired. 11 replanted digits without nerve repair regained some sensory recovery with a mean of 9.6 mm s2PD. 91% of patients were highly satisfied with the appearance of the replanted digits based on Tamai criteria.ConclusionsArteriovenous anastomosis for venous outflow should be considered during zone I fingertip replantation if sufficient veins are not identified in the amputated part. This technique may allow for more routine and successful distal replantation. 相似文献
