Spontaneous renal artery dissection in Ehlers-Danlos syndrome.: Byung Hun Lim, Song I Lee, Jae Hong Lim, Su Jin Oh, Min Su Chu, Seon Ho Ahn, Seung Jae Byun; Yeungnam Univ J Med. 2016;33(1):44-47. Published online June 30, 2016; DOI: https://doi.org/10.12701/yujm.2016.33.1.44

Abstract PDF: Primary dissection of the renal artery is rare. Spontaneous renal artery dissection can be associated with diseases such as medial degeneration, neurofibromatosis, syphilitic arteritis, tuberculosis, polyarteritis nodosa, Marfan syndrome, fibromuscular dysplasia, or Ehlers-Danlos syndrome (EDS). Among these causes, EDS related renal artery dissection is very rare worldwide and has not been previously reported in Korea. EDS are a group of heritable connective tissue disorders characterized by fragility of the skin and hypermobility of the joints. We describe the case history of a young man who presented with left side flank pain, hypermobility of the hand joints and showed left renal artery dissection on computed tomography and angiography that turned out to be the first complication of vascular type EDS.

Acute decompensated heart failure and acute kidney injury due to bilateral renal artery stenosis.: Ho Jin Jung, Won Suk Choi, Hyun Jae Kang, Byung Chun Jung, Bong Ryeol Lee, Jong Joo Lee, Jun Young Lee; Yeungnam Univ J Med. 2015;32(2):146-151.

Abstract PDF: Atherosclerotic renal artery stenosis (RAS) may result in hypertension, azotemia, and acute pulmonary edema. We report on a renal angioplasty with stent placement for bilateral RAS in a patient with acute decompensated heart failure and acute kidney injury. A 67-year-old female patient was admitted to our hospital with acute shortness of breath and generalized edema. Echocardiography showed left ventricular wall motion abnormality and the follow up electrocardiography showed T wave inversion in the precordial leads. We performed a coronary angiography to differentiate ischemic heart disease from non-cardiac origin for the cause of the heart failure. The coronary angiography showed no significant luminal narrowing, but bilateral RAS was confirmed on the renal artery angiography, therefore, we performed renal artery revascularization. After the procedure, the pulmonary edema was improved and the serum creatinine was decreased. Two weeks later, an echocardiography showed improvement of the left ventricular systolic function.

A Case of Extraadrenal Pheochromocytoma Showed a Transient Oral Captopril Test Positive Result.: In Bum Lee, Du Ha Lee, Tae Hi Oh, Jong Seon Park; Yeungnam Univ J Med. 1997;14(2):474-482. Published online December 31, 1997; DOI: https://doi.org/10.12701/yujm.1997.14.2.474

Abstract PDF: There have been some case reports of the coexitence of extraadrenal pheochromocytoma and renal artery stenosis. Some reporters proposed that their coexistence may be associated through a common pathophysiological mechanism mediated by catecholamine secretion. Also some noted that trasient renal artery stenosis due to a spasm was induced by the catecholamines released from pheochromacytoma. We report a case of left paraaortic extraadrenal pheochromacytoma that had a transient oral captopril test positive result. After 5 days alpha-antagonist reduced the vasospastic response of catecholamines. After surgical removal of the tumor, plasma catecholamines and urinary vanillymandelic acid concentrations as well as the blood pressure level, were restored to normal.
