Vascular grafts are often required in clinical stiuations to bridge arterial or venous grafts. Numerous studies exist in the literature concerning the results of such arterial and venous graft of relatively large vessels. There are only a few reports dealing with experimental microvascular grafts. Histopathological features of the grafted vessels were studied after autogenous venous grafts,autogenous arterial grafts and venous allografts using microsurgical techniques. The results were summerized as follow. 1. The patency rate of grafted vessels by microsurgical techniques was 86.8%. 2. In autogenous venous grafts histopathological changes occur later, and to a less pronounced degree, than that in autogenous arterial grafts. 3. Venous allografts showed severe acute inflammatory reaction throughout the layer at 3~7 days postoperatively, but histopathological features of grafted vessels of autografts and venous allografts' did not differ each other in later results. 4. Autogenous venous grafts, autogenous arterial gtafts and venous allografts persist as living sucture but undergo certain histological changes consisting of fibrous reinforcement. 5. It may be said that histological examination of the specimen led general conclusion that the most useful microvascular graft to reestablish circulation of damaged vessels is the autogenous venous graft, but autogenous arterial graft and venous allograft are also applicable when autogenous venous tissue is not available.

Autogenous bone-patellar tendon-bone is popular ligament substitute used in anterior cruciate liga- ment(ACL) reconstructions. Fracture of the patella is a rare but serious complication unique to this type of reconstruction. We report 4 cases of patellar fracture after autogenous bone-patellar tendon-bone ACL reconstruction.

PURPOSE: To investigate the types of corneal higher-order aberration (HOA) induced by pterygium, residual corneal HOA after pterygium surgery, and correlations between corneal HOA and the length of the pterygium. METHODS: Fifty-three patients who underwent pterygium excision with conjunctival autograft were enrolled. Corneal HOA was measured by Pentacam® (Oculus Inc., Wetzlar, Germany) preoperatively and 3 months postoperatively in the 6-mm optical zone. Preoperative and postoperative HOAs of eyes with pterygium were compared with HOAs of the fellow eye to evaluate HOAs induced by pterygium and residual HOAs after pterygium surgery. Partial correlation analysis was performed to investigate the relationship between HOAs and the length of pterygium. A postoperative HOA less than 0.35 µm in size was defined as a favorable surgical outcome and the surgical indications were estimated using receiver operator characteristic (ROC) curve. RESULTS: Horizontal coma, root mean square (RMS) of coma, oblique trefoil, horizontal trefoil, RMS of trefoil, and total HOA were significantly greater in the eye with preoperative pterygium. Three months after pterygium excision, only RMS of coma and total HOA remained significantly greater in eyes with pterygium. Vertical coma, horizontal coma, RMS of coma, and oblique tetrafoil were correlated with pterygium length. Pterygium excision when pterygium length was less than 1.6 mm led to favorable surgical outcomes. CONCLUSION: Pterygium induced greater than third-order corneal HOAs and these HOAs were corrected via pterygium surgery. Longer pterygium length was associated with larger RMS of coma and larger coma RMS persisted after pterygium surgery. A pterygium length of 1.6 mm should be considered the cutoff for pterygium excision for reducing postoperative corneal HOA.
