The anatomical research of grafting ring finger radial digital branch of median nerve for repairing injuried deep branch of ulnar nerve defects / 中华显微外科杂志

ObjectiveTo provide anatomical basis of neural transplantation to repair deep branch of ulnar nerve defect with the ring finger radial digital branch.MethodsThirty-two sides of 16 cases fresh forearms were dissected and observed.Microdissect and measure the deep branch of ulnar nerve,quadrate pronator of median nerve and it's ring finger radial digital branch under 10-times operating microscope. ResultsThe diameter of quadrate pronator of median nerve was (1.13 ± 0.02)mm,ring finger radial digital branch of median nerve was (1.17 ± 0.05)mm,mid-palmar section of deep branch of ulnar nerve was(1.75± 0.07)mm.Dissect ring finger radial digital branch of median nerve to muscular branch of quadrate pronator under operating microscope,retaining it's blood supply.The length between the deep branch of ulnar nerve and ring finger radial digital branch was( 104.59 ± 20.25)mm.Conclusion①Solving the problem of nervegrafting without blood supply before,benefit to the survival of the grafting segment and the regeneration of the neuro fiber,and function restoring.②This kind of grafting is the bridging of muscular branch to muscular branch,abide by the principle of neurophysiology.③Neural transplantation to repair deep branch of ulnar nerve defect with the ring finger radial digital branch is an effective method.

Space occupying lesion of the spleen / 中国普通外科杂志

Objective To summarize the experience in diagnosis and management for the space occupying lesion of spleen. Method The clinical data of 29 cases treated by surgery were retrospectively analyzed. Results There were 15 patients with benign masses including 7 hamartomas, 5 hemangiomas, 1 pseudocyst, 2 tuberculoses of the spleen, and 14 with malignant tumors including 9 lymphomas, 3 angiosarcomas, 2 metastatic tumors in the spleen. Splenectomy was performed in all patients. All patients with benign masses survived except 2 patients lost follow up and 1 coexisting with hepataocellular carcinoma died half a year after the operation. Twelve of 14 patients with malignant tumor were followed up.Of them, 5 patients survived more than 5 years and 2 were alive 1 and 3 years after the operation respectively; 5 patients died 6 months to 4 years after the operation. Conclusions Ultrasonography and CT or MRI are the main means of diagnosis for the space occupying lesion of spleen.It is difficalt to make diagnosis of the splenic tuberculosis before operation.Splenectomy is a primary procedure of surgery.
