Fissure-in-ano: The initial management and prognosis

SummaryIntra-arterial thrombolytic therapy has replaced systemic intravenous infusion of thrombolytic agents as a treatment modality for arterial occlusion in the limbs. Several catheter-guided techniques and various infusion methods and schemes have been developed. At present there is no scientific proof of definite superiority of any agent in terms of efficacy or safety but clinical practice favours the use of urokinase or alteplase. Studies which compared thrombolysis to surgical intervention suggest that thrombolytic therapy is an appropriate initial management in patients with acute occlusion of a native leg artery or a bypass graft. Underlying causative lesions are treated in a second step by endovascular or open surgical techniques. Severe bleeding is the most feared complication: the risk of hemorrhagic stroke is 1-2%.

Object. Recent studies have suggested a high incidence of cognitive deficits in patients undergoing high-dose chemotherapy, which appears to be dose related. Whole-brain radiotherapy (WBRT) has previously been associated with cognitive impairment. The authors attempted to use gamma knife radiosurgery (GKS) to delay or avoid WBRT in patients with advanced breast cancer treated with high-dose chemotherapy and autologous bone marrow transplantation (HDC/ABMT) in whom brain metastases were diagnosed. Methods. A retrospective review of our experience from 1996 to 2001 was performed to identify patients who underwent HDC/ABMT for advanced breast cancer and brain metastasis. They were able to conduct GKS as initial management to avoid or delay WBRT in 12 patients following HDC/ABMT. All patients were women. The median age was 48 years (range 30–58 years). The Karnofsky Performance Scale score was 70 (range 60–90). All lesions were treated with a median prescription dose of 17 Gy (range 15–18 Gy) prescribed to the 50% isodose. Median survival was 11.5 months. Five patients (42%) had no evidence of central nervous system disease progression and no further treatment was given. Four patients were retreated with GKS and three of them eventually received WBRT as well. Two patients were treated with WBRT as the primary salvage therapy. The median time to retreatment with WBRT was 8 months after the initial GKS. Conclusions. Gamma knife radiosurgery can be effectively used for the initial management of brain metastases to avoid or delay WBRT in patients treated previously with HDC, with acceptable survival and preserved cognitive function.
