Resection for progressively growing giant hemangioma of anterior abdominal wall.

Hemangioma is a benign vascular malformation and generally diagnosed in childhood. This pathology frequently shows regression within the first decade of life, but it rarely presents in young adults beyond 12 years of age. When progressive growth of the tumour leads to a giant hemangioma with clinical symptoms, surgical resection can be reasonable despite its high risk of complications such as intractable bleeding or recurrence. Selective angiography for assessment of the blood supply to hemangiomas is a guide for the surgeon to remove the lesion safely. We present the case of a 20-year-old patient, who underwent successful surgical treatment for a giant hemangioma that showed progressive enlargement in the abdominal wall.

Prosthetic aortic valve endocarditis due to Stenotrophomonas maltophilia complicated by subannular abscess.

Annular abscesses are serious complications of infectious native and prosthetic valve endocarditis. In this patient, we isolated Stenotrophomonas maltophilia, a rare cause of subaortic abscess with high mortality/morbidity rates although virulent gram-positive cocci, S. Aureus in particular, have been the most commonly isolated agents. We treated this case of endocarditis and the subannular abscess observed 1 year after the initial operation by aortic root replacement with resternotomy in addition to appropriate antibiotics.

Thoracic endoscopic surgery for hyperhidrosis: comparison of different techniques.

BACKGROUND: Hyperhidrosis is pathological perspiration in palmar, plantar or axillary surfaces. Video-assisted thoracic surgery (VATS) is currently the most commonly used therapy for hyperhidrosis. Blockage of sympathetic ganglia is achieved by segmental resection, transection and/or cauterization, and clipping of the chain. We aimed to compare the efficacy of these methods with respect to patient satisfaction, recurrence of symptoms and complications. METHODS: Eighty male patients with a mean age of 22.02 +/- 2.61 years undergoing bilateral thoracoscopic sympathectomy or sympathetic blockage to treat primary hyperhidrosis were included in this randomized study. The patients were divided into four groups depending on the technique used for sympathetic blockage; techniques included resection (n = 20), transection (n = 20), ablation (n = 20), and clipping (n = 20). RESULTS: The primary success rate for isolated palmar hyperhidrosis was 96.3 %; for palmar and axillary hydrosis it was 95.7 % and for palmar and face/scalp hyperhidrosis it was 66.7 %. No recurrence was observed. The overall success rate of the operation was 95 % and the differences between the four groups were not statistically significant. In the clipping group, the duration of the surgical procedure was significantly shorter than in the other groups. Complication rates were similar among the groups. The postoperative chest roentgenogram revealed pneumothorax in nine patients, but none of them required intervention. CONCLUSION: Thoracic endoscopic sympathetic blockage yields similar results irrespective of the surgical technique adopted.

A retrospective comparison of bovine pericardium and polytetrafluoroethylene patch for closure of ventricular septal defects.

This retrospective study compared the immediate post-operative (first month) and mid-term (up to 5 years post-operation) results of 22 patients with isolated ventricular septal defects who underwent surgical correction with bovine pericardium with 57 similar patients who received a polytetrafluoroethylene (PTFE) patch. There were no cases of early (in the first month) mortality in either group and the 3-month post-operative echocardiographical studies showed no evidence of calcification or aneurysm formation around the patch. Recurrent ventricular septal defects due to dehiscence of the patch occurred in the early follow-up period in four patients who had the PTFE patch but this was not statistically significant. Annual echocardiographical examination revealed some calcification in both groups. We conclude that although there are no significant differences between the two materials in outcome after ventricular septal defects closure, we prefer bovine pericardium because of its handling characteristics, elasticity and the lower risk of endocarditis.
