Phaeochromocytoma is a rare surgically treatable cause of hypertension. The aim of this paper is to present a case of phaeochromocytoma treated in Port Harcourt.
The case record of a patent with phaeochromocytoma and a review of the relevant literature.
A 40 year-old man presented with episodic malignant hypertension resistant to several anti-hypertensive drugs. A 24-hour urinary Vanillyl Mandelic Acid estimation was high at 68 mmol. An ultrasound scan revealed a huge right suprarenal mass. Preoperative medication was given to reduce the blood pressure and prevent perioperative arrhythmias. Under general anaesthesia with propofol, the tumour was explored. It appeared to invade the kidney and there were multiple hepatic secondaries. It was resected in block with the kidney. Intra- and postoperatively he had episodes of hypertension which were successfully controlled with a combination of intravenous chlorpromazine 50 mg, tramadol 100 mg and lorazepam 4 mg. Histopathology examination showed that the suprarenal mass and hepatic lesions were identical showing malignant phaeochromocytoma. The post-operative period was satisfactory. Cytotoxic drugs were not given because they were not available. On review 8 weeks later, the patient remained well.
Meticulous anaesthetic and surgical skills are essential in the resection of a phaeochromocytoma.
嗜铬细胞瘤是一种罕见的可通过手术治疗的高血压病因。本文旨在介绍一例在哈科特港治疗的嗜铬细胞瘤病例。
一名嗜铬细胞瘤患者的病例记录及相关文献回顾。
一名40岁男性表现为对多种抗高血压药物耐药的发作性恶性高血压。24小时尿香草扁桃酸测定值较高,为68毫摩尔。超声扫描显示右肾上腺有一个巨大肿块。给予术前药物治疗以降低血压并预防围手术期心律失常。在丙泊酚全身麻醉下,对肿瘤进行探查。肿瘤似乎侵犯了肾脏,并有多个肝脏转移灶。肿瘤与肾脏一并整块切除。术中及术后他出现高血压发作,通过静脉注射50毫克氯丙嗪、100毫克曲马多和4毫克劳拉西泮联合用药成功控制。组织病理学检查显示肾上腺肿块和肝脏病变相同,均为恶性嗜铬细胞瘤。术后情况良好。由于没有细胞毒性药物,未给予此类药物。8周后复查时,患者情况良好。
在嗜铬细胞瘤切除术中,精细的麻醉和手术技巧至关重要。
