|Title:||Surgery and Anesthesia for Pheochromocytoma - A Series of 40 Operations|
|Citation:||Journal of the Medical Association of Thailand. Vol.83, No.8 (2000), 921-927|
|Abstract:||Pheochromocytoma is a catecholamine-producing tumor which can be life-threatening. A series of 40 operations in 39 pheochromocytoma patients at a tertiary hospital in Thailand from 1976 to 1997 was reported. The patients were 30 females and 9 males; aged 7-73 years. One man had 2 operations 5 years apart. The most common symptoms and signs were palpitation, headache and hypertension. Preoperative management consisted of control of blood pressure and restoration of intravascular volume by using prazosin, an alpha adrenergic blocker. New imaging techniques have improved the ability to localize the tumors; 20 were found in the right adrenal giands, 14 in the left, 1 patient had bilateral tumors, 4 in Organs of Zuckerkandl and 1 patient had metastatic liver nodules. The operative procedures were 39 laparotomies and 1 laparoscopic surgery. The surgical and anaesthetic procedures were presented, and nitroprusside was used to control intra-operative blood pressure. Removal of tumors was successful in all cases except for 1 mortality due to injury of the liver and massive blood loss. Other complications were postoperative pulmonary edema and renal vein thrombosis. One patient had MEN type 2 and five cases were malignant. Pheochromocytoma can be cured by surgery, but cooperation among surgeons, anesthesiologists and internists is very important.|
