Hiperaldosteronismo primário, como descrito por Conn. Relato decaso / Hyperaldosteronism, as described by Conn. Case report

O hiperaldosteronismo primário é causa de hipertensão arterialsecundária, com possibilidade de cura após cirurgia em 30a 75% dos casos. O objetivo deste estudo foi relatar um casode hipertensão arterial secundária a adenoma adrenal produtorde aldosterona. Paciente feminino, 35 anos, natural de Beruri(AM), procedente de Manaus, foi admitida com pressão arterialde 220x125mmHg associada a fraqueza muscular de membrosinferiores e câimbras. Na história patológica pregressa, havia orelato de hipertensão arterial diagnosticada há 2 anos, em tratamentocom três classes de anti-hipertensivos. Durante internaçãoem hospital geral, o quadro relatado associado à hipocalemiae alcalose metabólica sugeriram diagnóstico de hipertensão arterialsecundária a hiperaldosteronismo primário. Níveis elevadosde aldosterona plasmática, com renina suprimida e relação aldosterona-renina elevada, confirmaram o diagnóstico de hiperaldosteronismoprimário. A tomografia computadorizada deabdome evidenciou lesão tumoral com 2,3x2,0cm em glândulasuprarrenal esquerda sugestiva de adenoma adrenal. Pacientefoi submetida a adrenalectomia à esquerda com histopatologiacompatível com adenoma adrenal. Seis meses após a cirurgia,paciente evoluiu com normalização da calemia, porém mantevehipertensão arterial com necessidade de terapia anti-hipertensiva,sem novos picos hipertensivos. Se hiperaldosteronismo primáriodiagnosticado precocemente, há possibilidade de cura dahipertensão arterial secundária após adrenalectomia, reduzindo o efeito deletério da mesma sobre os sistemas cardiovascular, cerebrovasculare renal.(AU)

The primary hyperaldosteronism is a cause of secondaryhypertension, with the possibility of healing after surgery in 30to 75% of cases. The objective of this study was to report a caseof secondary hypertension to aldosterone-producing adrenaladenoma. A female patient, 35 years, from Beruri (AM), Brazil,who came to Manaus, was admitted into the emergency room withblood pressure of 220x125mmHg, associated with lower limbmuscle weakness and cramps. In the past medical history, there wasa report of hypertension diagnosed 2 years before, and she was undertreatment with three classes of antihypertensive drugs. Duringhospitalization in a general hospital, the case reported associatedto hypokalemia and metabolic alkalosis suggested a diagnosis ofhypertension secondary to primary hyperaldosteronism. Elevatedlevels of plasmatic aldosterone, suppressed renin and highaldosterone-renin relation suggested primary hyperaldosteronism.The abdominal computerized tomography scan revealed a tumor of2.3x2.0cm in the left adrenal gland, suggesting adrenal adenoma.Patient underwent left adrenalectomy and histopathology wascompatible to adrenal adenoma. After 6 months of surgery, thepatient experienced normalization of kalemia but kept arterialhypertension, requiring anti-hypertensive therapy, but had no othershypertensive peaks. Early diagnosis of primary hyperaldosteronismallowed the cure of hypertension after adrenalectomy, reducingdeleterious effects of high blood pressure levels on the cardiovascular,cerebrovascular and renal systems.(AU)

A laparoscopic versus open adrenalectomy in Ramathibodi Hospital.

OBJECTIVE: To compare the results of laparoscopic adrenalectomy with those of open adrenalectomy in Ramathibodi Hospital. MATERIAL AND METHOD: Medical charts of 41 laparoscopic and 39 open adrenalectomy patients were reviewed Baseline characteristics and outcomes of treatment were compared between these two patient groups, using univariable statistical tests and multivariable statistical procedures. RESULTS: There were significant baseline differences between the two groups in terms of gender, body mass index, ASA class, and preoperative diagnosis. The outcomes operative time, estimated blood loss and length of hospital stay were also significantly different. After adjusting for the effects of baseline differences, laparoscopic adrenalectomy was associated with a significant reduction of length of hospital stay by 40%. CONCLUSION: Laparoscopic adrenalectomy is a safe and effective procedure and should help hasten postoperative recovery and may save the costs of hospitalization.
