Objectives: Our objective was to assess the short- and long-term outcome for patients after carotid body tumor (CBT) resection and discuss the potential pitfalls of the treatment. Methods: An analysis was undertaken of all patients who underwent CBT resection at Royal Brisbane and Women''s Hospital and Greenslopes Private Hospital between 1982 and 2007. Primary tumor characteristics, surgical technique, and outcomes were recorded and analyzed. Results: A total of 49 consecutive CBT resections (2 recurrent tumors) were carried out in 39 patients (26 women [56%]) who were a mean age of 49 years (range, 17-75 years). A nontender neck mass was the presenting complaint in 85%, followed by screening in familial or contralateral tumors in 26%. Familial cases occurred in 11 patients (28%). There were no operative deaths. Complications occurred in 13 of the 49 operations (27%), predominantly temporary nerve palsies and were more likely to occur in tumors of large volume or in cases of removal of coexisting vagal tumors. Malignant disease was present in seven cases (15%). All patients have been followed-up postoperatively for a mean of 11 years (range, 2-26 years). Metachronous paragangliomas have been discovered in six patients, all with familial disease. Conclusions: Early resection of carotid body tumors should be undertaken while still small to minimize the risk of neural injury, which increases with tumor size. In cases of bilateral CBT, we recommend that the smaller tumor be resected first, before the staged resection of the larger contralateral tumor. In familial or bilateral tumor cases, other synchronous and metachronous paragangliomas should be excluded. Mandatory lifelong follow-up is essential. [Copyright &y& Elsevier]

Background: This study was undertaken to document the results of our current practice of open mesenteric revascularization to enable comparison with the recent trend of percutaneous endovascular therapy for the treatment of chronic mesenteric ischemia. Methods: Patients were identified via operation code data as well ongoing audit data from 1992 until 2006. Only patients with a history of chronic mesenteric ischemia secondary to atherosclerosis for 3 months or longer were included in the study. Follow-up data have been collected prospectively and include clinical examination and history, as well as graft surveillance consisting of mesenteric duplex ultrasonography, computed tomography, and/or angiography every 6 months for 3 years and then yearly thereafter. Results: Thirty-nine consecutive patients underwent 41 open revascularization procedures for chronic mesenteric ischemia, comprising 67 bypass grafts. The mean patient age was 65 years (range, 45-85 years), and 44% (n = 17) were male. Symptoms were present on average for 11 months (range, 4-48 months) before treatment. The average weight loss was 11.4 kg, and three patients (7.6%) also had evidence of ischemic enteritis. There was one perioperative death, thus giving a perioperative mortality rate of 2.5%. Perioperative morbidity occurred in five patients (12.2%). Primary graft patency was 92% at 5 years. Seven patients died during follow-up, which ranged from 4 to 161 months (mean, 39 months)—one (2.5%) from mesenteric ischemia. Two (5%) other patients have had recurrent mesenteric ischemic symptoms. Conclusions: Open surgical mesenteric revascularization by bypass grafting for atherosclerotic-induced chronic mesenteric ischemia can be performed with low mortality and morbidity and provides excellent long-term primary patency rates and symptom-free outcomes. Pending more data on the acute and long-term results of endovascular techniques, open mesenteric revascularization remains the gold standard for most patients with chronic mesenteric ischemia.
