Abstract:
Objective To analyze the complications caused by microwave ablation for hepatic cavernous hemangiomas, and to discuss the prevention and treatment of the complications. Methods During the period from July 2009 to May 2011 at authors’ hospital, a total of 34 times of microwave ablation procedure were carried out in 30 patients with hepatic cavernous hemangiomas. The microwave ablation-related complications were recorded and the prognosis was evaluated. Results Serious complications occurred in 2 patients (6.7%), including acute hemolysis leading to acute renal failure (n = 1) and abdominal wall abscess (n = 1). Postoperative fever was seen in 18 cases (60%), transient hemoglobinuria in 4 cases (13.3%), nausea with vomiting in 5 cases (16.7%), marked pain at the surgical area in 8 cases (26.7%), right pleural effusion in 4 cases (13.3%), hepatic dysfunction in 24 cases (80%) and leukocytosis in 11 cases (36.7%). No treatment-related death occurred. Conclusion For the treatment of hepatic cavernous hemangiomas, microwave ablation is minimally invasive with higher safety and satisfactory effect, although this technique carries somewhat higher risks when the hemangioma is larger or the location of the hemangioma is anatomically complicated. Some of these complications can be early detected and proper management should be actively adopted in order to avoid as well as to minimize the adverse results.
