Fingertip amputation salvage on arterial anastomosis alone: an investigation of its limitations.

BACKGROUND: We have previously reported the importance of adequate and precise arterial anastomosis and the hypothesis that, up to subzone III, fingertip amputation salvage can be achieved on arterial anastomosis alone. These findings were reported during the meeting of the Japanese Society of Reconstructive Microsurgery. This is our follow-up report with insight and opinion on the limitations of complete fingertip amputation salvage on arterial anastomosis alone. METHODS: We examined 67 fingers (59 patients) with fingertip amputations presenting to our hospital between January 2005 and December 2008. Amputation levels and whether these injuries received only arterial or both arterial and venous anastomoses were noted. Fisher exact test was used to examine statistical differences between the groups. RESULTS: Amputation levels were 11 in subzone I, 20 in subzone II, 17 in subzone III, and 19 in subzone IV. Successful replantation was achieved in 87% (58 of 67) of fingers. There was no statistically significant difference between fingers receiving arterial alone versus both anastomoses in amputations of subzones I, II, and III. CONCLUSIONS: We found that with proper postoperative congestion care, no statistically significant difference in replantation success of fingers receiving arterial anastomosis alone versus both arterial and venous were noted up to subzone III. However, in subzone IV, regardless of the postoperative congestion, compete necrosis rates are high; thus, it is speculated that a venous anastomosis is necessary for successful replantation. It is preferable to perform as many anastomoses as possible, but we believe that it is also desirable for the procedure to be fast and less invasive. In cases that have no adequate vein, fingertip replantation can be achieved on arterial anastomosis alone up to subzone III.

Treatment of paralytic lagophthalmos by loading the lid with a gold plate and lateral canthopexy.

Various methods of managing patients with lagophthalmos secondary to paralysis of the facial nerve have been reported. While addition of a gold plate facilitates displacement of the upper eyelid downwards, coaptation of the lid margin is often incomplete because of coexisting ectropion of the lower lid. The outcome obtainable from loading the lid with a gold plate alone is often unsatisfactory. To manage the deformity by combining the loading of the lid with gold plate and lateral canthopexy is technically simple. Morbidity is minimal as it can be done under local anaesthesia. Adequacy of coaption of the palpebral margin could be assessed immediately. We have managed a total of seven (mainly elderly) such patients between 1999 and 2000 in our hospitals. The outcome was generally satisfactory and there were no complications.

Use of an arterialised venous skin flap in the replantation of an amputated thumb.

We report the replantation of an amputated thumb using a venous skin flap, harvested from the volar surface of the forearm, to make up the soft tissue defect, and to restore the vascular continuity to the thumb.
