Background: The purpose of this study was to clarify the appropriate use of unfractionated heparin as an anticoagulation agent after digital replantation. Methods: This study was a prospective, randomized, single-blind, blinded-endpoint method, three-arm, parallel-group, controlled clinical trial conducted at a single institution. A total of 88 patients (101 fingers) following digital amputation and subsequent repair by anastomosis of both arteries and veins were randomly allocated into three groups: (1) control group (no heparin dose), (2) low-dose heparin group (10,000 IU/day), and (3) high-dose heparin group (start at 15,000 IU/day, then adjust the dose to achieve an activated partial thromboplastin time of 1.5 to 2.5 times the baseline). The outcomes were assessed regarding the proportion of success at 2 weeks after replantation of amputated digits, total or partial necrosis, and occurrence of complications. Results: No significant differences were found among the three groups, except for complications of congestion. The odds ratio of the heparin group compared with the control group for a success proportion was 5.40 (95 percent CI, 0.85 to 34.20; p = 0.027) in subjects aged 50 years or older. Significant elevations of activated partial thromboplastin time, aspartate transaminase, and alanine aminotransferase occurred in high-dose heparin groups on day 7. Conclusion: Unfractionated heparin administration is considered effective for patients aged 50 years or older, although the routine use of unfractionated heparin is not necessary after digital replantation. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, II.
Purpose: To report a case of large sarcoid choroidal granuloma that was successfully treated with steroid pulse therapy. Case Report: A 38-year-old man presented with the primary complaint of decreased visual acuity (VA) in his left eye. Upon examination, a large white protruding lesion of 10 × 8 papilla diameter in size was observed in the macular region, and slightly temporal to it, in the patient's left eye. Whole-body contrast-enhanced computed tomography performed for differential diagnosis detected numerous enlarged lymph nodes throughout the body, including the bilateral hilar regions. Sarcoidosis was diagnosed by biopsy of the right cervical lymph nodes showing noncaseating epithelioid cell granuloma. The fundus lesion was found to be a choroidal granuloma caused by sarcoidosis, and steroid pulse therapy was started. The granuloma was considerably decreased, and the VA in the left eye improved to 0.7 after 2 months. Conclusion: Steroid pulse therapy was found to be effective as an initial treatment for a large sarcoid choroidal granuloma.
