Coronary heart disease is a kind of heart disease that is caused by atherosclerosis. The lipid deposition in the vessel wall results in occlusion of coronary artery and stenosis, which could induce myocardial ischemia and oxygen deficiency. Intervention therapies like percutaneous coronary intervention (PCI) and coronary stent improve myocardial perfusion using catheter angioplasty to reduce stenosis and occlusion of coronary artery lumen. Accordingly, intervention therapies are widely applied in clinic to treat ischemic cardiovascular disease, arterial intima hyperplasia and other heart diseases, which could save the patients' life rapidly and effectively. However, these interventions also damage the original endothelium, promote acute and subacute thrombosis and intimal hyperplasia, and thus induce in-stent restenosis (ISR) eventually. Studies indicated that the rapid reendothelialization of damaged section determined postoperative effects. In this review, reendothelialization of implants after intervention therapy is discussed, including the resource of cells contributed on injured artery, the influences of implanted stents on hemodynamic, and the effects of damaged degree on reendothelialization.

Objective To explore the effect of shifting the little finger abductor muscle and cutting open the metatarsophalangeal joint dorsal articular capsule to improve the appearance and function of reconstructed thumb.Methods From August 2007 to May 2012,twelve cases of Ⅳ°or Ⅴ°defect of thumb were repaired by free transplantation of the second toes with metatarsophalangeal joint.During operation,using the abductor muscle of little finger to reconstruct palmar opposition function,cutting open the joint capsule of metatarsophalangeal joint,adjusting the tension of the joint by the little finger abductor muscle and toe short extensor muscles,which were used to improve the appearance and function of reconstructed thumb.Results Twelve reconstructed thumbs all survived.Followed up from 6 to 24 months,the appearance and function were improved obviously.According to the evaluation trial standards,nine cases were optimal and 3 cases were good.Conclusion The shift of the little finger abductor muscle could reconstruct palmar opposition function,combined with metatarsophalangeal joint dorsal articular capsule incision and adjusting joint tension,could improve the appearance and function of reconstructed thumb.The effect of operation was satisfied.

Objective To introduce the improvement of the flap from the dorsal site of the index in the application of treatment in the thumb web contracture. Methods Apply improved first dorsal metacarpal flap for 111 cases of patients of the thumb web contracture releasing. The original island or tongue-shaped flaps was modified to be the local flap transfer to the thumb web. Surgical method simplified. Before thumb web contracture was released, the flap was taken from ulnar aspect to radial aspect on the dorsum of the index. The flap was transferred to cover the soft tissue defect on the first web space following the contracture releasing. Flap donor area was closed by split-thickness skin graft. Results One hundred and eleven cases of flaps survived. After the 3-18 months (mean follow-up of 8.5 months), the local appearance, thumb function recovered well for 94.6 percent. Conclusion Improved first dorsal metacarpal flap is effective methods in thumb web contracture releasing.

Objective To investigate the outcome of the finger reconstruction using one toe transfer to repair the tissue defects of two fingers at the same time. Methods Two fingers joint tissue missing and finger defect of 8 fingers in 4 cases were reconstructed with dissociative transplants harvested from two parts of the same toe at the same time.Using the paratelum of the second toes reconstructed the indicis paratelum or finger tip,and using the proximal interphalangeal joint of the second toes repaired the proximal interphalangeal joint's tissue defects of the middle finger at the same time in 2 cases.Using the distal interphalangeal joint and the proximal interphalangeal joint of one second toe reconstructed the proximal interpha langeal joints of the index finger and the middle finger in 1 case.Using the proximal interphalangeal joint and the metatarsophalangeal joint of one second toe reconstructed the metacarpophalangeal joints of the index finger and the middle finger in 1 case. Results All the transplants survived.The patients were followed-up from 2 months to 46 months postoperatively.The function and shape of 2 resconstruction fingers were excellent as assessed with Criterion on Functional Evaluation on Finger Reconstruction issued by Chinese Society of Hand Surgery.Five resconstruction fingers were good.One resconstruction finger was fire. Conclusion For some appropriate cases with the tissue defects of 2 fingers such as the finger's paratelum,the interphalangeal joint or the metacarpophalangeal joint,this operated technique was a good method.

ObjectiveTo investigate the technique and clinical results of curved osteotomy under the metatarsal head's cartilage for improving reconstructed metacarpophalangeal joint function of fingers with second toe transplantation. MethodsThere were total 21 cases with 21 digits. During second toe transplantation with the metatarsophalangeal joint, the bottom of the second metatarsal head was incised. Then a curved osteotomy were carried out on about 5.0 mm under the metatarsal head's cartilage until the passive range of motion could be 90°.Longitudinal or cross-Kirschner wires were used to fix the joint.Finally,the conventional methods were used to reconstruct the blood supply, movement and nerves. ResultsAll 21 digits of the 21 cases survived uneventfully.The follow-up time was ranged from 6 to 24 months.Their average passive range of motion of the reconstructed metacarpophalangeal joint was 75°,ranging from 65° to 85°.The average active range of motion was 65°, ranging from 45° to 80°. Postoperative X-ray revealed fracture healed well without joint degeneration. ConclusionCurved osteotomy under the metatarsal head's cartilage is an effective way to improve active and passive activities function of the reconstructed metacarpophalangeal joint with second toe transplantation.

Objective To explore small size toe tissue flap for aesthetic reconstruction of the thumb and / or finger. Methods Six kinds of small size toe tissue transplants had been applied in repairing skin-bone-joint composite tissue defects of the thumb or finger in 74 cases. Results Among 83reconstructed flaps of the 74 patients, 81 flaps survived completely. Follow-up examination made three to forty-eight months postoperatively showed that the outward appearance were excellent in most cases. The function of the thumbs or fingers were good. The donor feet can walk normally with no pain. Conclusion A variable combinations of toe tissues including skin, soft tissue, bone and joint can be harvested to form a lot of small size transplants for refined aesthetic reconstruction of thumb and finger. The functional and aesthetic results are good and the treatment course is shortened.

Objective To introduce the concept of long length finger reconstruction and our corresponding three operative methods. Methods In a series of 10 finger defect cases with one of their long finger amputated at or proximal to proximal phalanx, long finger reconstruction were accomplished with one of the three methods. First method: For emergency patients whose proximal finger segment were demolished, the donor second toe was transplanted intercalatedly with microsurgical technique between the original proximal finger stump and the saved distal finger segment. Second method: Bilateral second toes were harvested and connected together to form a long transplant in order to reconstruct a normal length finger. Third method: From one foot, the donor second toe is harvested with its dorsal and plantar skin flap. From the other foot, the second toe is harvested with its metatarsophalangeal joint and skin flaps from neighbouring sides of great and third toes. The skin covering will be perfect. During transplantation of the proximal transplant, the MPJ should be fixed at 90°plantar rotation position for better flexion. Results Uneventful survival of reconstructed fingers were obtained in all ten cases. Postoperative functional evaluation of the patients with standard set by Chinese Society of Hand Surgery showed to be excellent in 1 case, good in 5 cases and fair in 4 cases. The overall excellent/good rate was 60%. Conclusion By application of these three reconstruction methods, the challenging problem of long length finger can be solved to reasonable extent.
