RESUMO
In the framework of implementation of his national program for control and prevention of cardiovascular diseases, Cameroonian government has set up a cardiac surgery project. We report in this manuscript results of one year follow up of the patients operated during the pilot phase. From September 22 till 26, 2008, 11 patients have been operated in Cameroun. Surgical procedures were 5 mitral mechanic valve replacement, 2 aortic mechanic valve replacement, 1 atrial septal defect closure, 2 pace maker implantation. No intrahospital death was observed. One patient died at 11th month after the operation due to mitral valve thrombosis and attributed to lack of compliance. One patient presented low cardiac output, pneumonia and a pleural effusion. 2 patients presented 2 minor complications consisting of pericarditis and superficial wound infection. The results of the pilot phase of cardiac surgery in Cameroon are effective. However, the sustainability of the program require human, material capacity building, and funding mechanism as well.

The aim of this study was to describe methods used for diagnosis of pheochromocytoma inYaoundé, Cameroon. This retrospective study was based on analysis of the charts of patients treated in the surgical department of the Yaoundé University Teaching Hospital from 1985 to 2009. Nine patients with histologically confirmed pheochromocytoma were identified. There were 8 women and 1 man with a mean age of 39.5 years (range, 12 and 66). Pheochromocytoma was associated with hypertension in 6 cases. In two women with hypertension, diagnosis was based on palpation of an abdominal tumor after caesarean section following pregnancy associated with arterial hypertension. In another woman, diagnosis was made during laparotomy for a left hypochondrial tumor. In 7 patients, diagnosis was based on laboratory findings showing high urinary levels of vanyl mandelic acid (VMA). In six patients, ultrasound examination allowed topographic diagnosis that was confirmed by CT-scan in 3 cases. Two patients presented extra-renal pheochromocytomas in the abdomen. In three patients, i.e., one third of cases, histology showed malignant features. The findings of this study indicated that diagnosis of pheochromocytoma in Yaoundé be improved with the introduction MRI, scintigraphy, and modern techniques for assaying urinary methoxyderivates.
