2. explain hypertansion and renal disease interaction, describe renovascular diseases describe diagnostic evaluation explan therapy in renovascular deseases describe and manage renal artery and vein thrombosis explain microvascular renal diseases

5.  Asemptomatic ‘’İncidental Renal Artery Stenosis’’  Renovascular Hypertension  İschemic Nephropathy  Accelerated CV Disease -Congestive heart failure -Stroke -Secondary aldosteronism

6.  Asemptomatic ‘’İncidental Renal Artery Stenosis (RAS)’’  Renovascular Hypertension  İschemic Nephropathy  Accelerated CV Disease -Congestive heart failure -Stroke -Secondary aldosteronism

7.  Some degree of RAS can be identified in 20%- 45% of patients undergoing vascular imaging  Most of these stenoses are of little or no hemodynamic significance

8.  Asemptomatic ‘’İncidental Renal Artery Stenosis (RAS)’’  Renovascular Hypertension  İschemic Nephropathy  Accelerated CV Disease -Congestive heart failure -Stroke -Secondary aldosteronism

10.  Reduced renal perfusion Rise in arterial pressure  Diagnosis is established only in retrospect after succesful reversal of HT with revascularization

12.  3%-5%, F>M  Medial fibroplasia is the most common  Location: midportion of the vessel  Smoking is a risk factor for progression

14.  Most common renovascular lesion (75% - 84%)  Location: origin of artery  Associated with HT, DM, HPL, smoking, abnormal renal function

25.  Asemptomatic ‘’İncidental Renal Artery Stenosis’’  Renovascular Hypertension  İschemic Nephropathy  Accelerated CV Disease -Congestive heart failure -Stroke -Secondary aldosteronism

28.  Establish presence of RAS: location and type of lesion  Establish whether unilateral or bilateral stenosis (or stenosis to a solitary kidney)  Establish presence and function of stenotic and nonstenotic kidneys  Establish hemodynamic severity of renal arteral disease  Plan vascular intervention

29.  Physiologic and functional studies of the Renin-Angiotensin system -plasma renin levels -measurement of renal vein renin levels  Noninvasive imaging and assesment of the renal vasculature -Doppler USG -radyonuclide imaging -magnetic resonance arteriography -computed tomographic angiography

37.  Improved BP  Prevent morbidity and mortality  Preservation of renal function

38.  Medical therapy  Surgical therapy -angioplasty -angioplasty and stent replacement

54.  Hemolytic- Uremic Syndrome (HUS)  Thrombotic- Thrombocytopenic Purpura (TTP)

55.  Microangiopathic hemolytic anemia  Thrombocytopenic purpura  Acute renal failure  Fever  Neurologic dysfunction
