Left Renal Vein Entrapment Syndrome:Analysis of Two Cases of Misdiagnosis and the Literature Review
ZHAO Feng
Abstract：Objective To investigate the clinical characteristics, diagnosis and treatment measures, causes and pre-ventive measures for misdiagnosis of the left renal vein entrapment syndrome in order to raise awareness of the disease and pre-vent misdiagnosis. Methods Two recently misdiagnosed cases of the left renal vein entrapment syndrome admitted to our hos-pital were analyzed retrospectively. Results In one case, the patient had a 1-year history of hematuria, and sought for medi-cal care after two days of odynuria;in the other case, the patient had a 3-year history of hematuria, and sought for medical care due to hematuria one day after physical exercise. Both cases had been misdiagnosed as occult nephritis, and were diag-nosed as the left renal vein entrapment syndrome after the color doppler ultrasonography revealed that the ratio of left renal vein diameters distended to the narrowed portions exceeded 3∶ 1. The second case was also complicated by varicoceles on the left side. A 6-month and 3 year follow-up showed that symptoms were relieved after increasing body weight and avoiding vigorous physical activity. Conclusion The clinical characteristics of the left renal vein entrapment syndrome are not distinctive, but may be presented as hematuria and/or albuminuria, varicoceles, etc. Diagnoses can be made based on color doppler ultra-sonography results, clinical manifestations, and exclusion of other diseases. Improved knowledge and overall in-depth analysis may help to prevent or reduce misdiagnosis rate.
