Background: The change of blood pressure during hemodialysis has been noted for long time. However, there were few studies on the rise of blood pressure during hemodialysis. The clinical meaning of hypertension during hemodialysis has not been understood clearly. Objective: To study the role of calcium concentration in dialysate in the rise of blood pressure during hemodialysis sessions. Subjects and method: Prospective study performed on 9 stable patients on chronic hemodialysis treated at Viet Duc Hospital including 5 female and 4 male patients. The mean age of patients was 47.6 years. The patients had period 1 of 10 weeks of treatment using dialysate 1 A (with calcium concentration 1.8 mmol/l) and then they were switched to period 2 of 10 other weeks using dialysate 3A (with calcium concentration 1.25 mmol/l). Results:The blood pressure of patients during the period 2 using 3A dialysate was better controlled during hemodialysis sessions. The response to erythropoietin treatment was similar in both periods. The serum calcium was lower after using 3A dialysate. Conclusions: Using dialysate with lower calcium concentration can be helpful for controlling the hypertension during hemodialysis sessions. The appropriate calcium concentration in dialysate needs to be selected to avoid the hypocalcaemia in chronic hemodialysis patients.

Renal hypertension is found to be the cause in 5-15ft of patients with hypertension, and may be vascular or parenchymal in nature. Renal studies in diagnostic technique and vascular reconstructive techniques now enable successful management in many patients with renal hypertension. We experienced one case of renovascular hypertension due to renal vein hypoplasia. This rare renal venous hypertension has been diagnosed preoperatively and can be cured by nephrectomy, so we reported this case with brief review of the literature.

Renal artery embolism is an uncommon event, but a correct diagnosis and appropriate treatment are often delayed. We report a case in which viability was sustained by surgical intervention 18 hours after an episode of embolism that produced hypertension.

Background: Hypertension is one of the most common complications in chronic renal failure (CRF) patients. Dyslipidemia in primary hypertension has been considered a risk factor of cardiovascular diseases and progression of CRF. Objectives: To determine lipid disorders CRF patients with hypertension and the correlations between lipid disorders and blood pressure level in CRF patients. Subjects and method: The descriptive cross-sectional study involved 107 CRF patients under 45 years old, who had preservative treatments and were monitored at Bach Mai Hospital from 2000 to 2003. They were divided into 2 groups: hypertension (n=78; 72.9%) and nonhypertension (n=29, 27.1%). Results: In comparison with nonhypertension group, patients in the hypertension group had higher level of serum creatinine (877.7+/-597.1 vs. 587.6+/-381 micromol/L, p< 0.01), total cholesterol (5.35+/-1.34 vs. 4.81+/-1.23 mmol/L, p< 0.05), ApoB (1.07+/-0.34 vs. 1.00+/-0.32 g/L) and CT/HDL-C ratio (5.33+/-2.2 vs. 4.9+/-1.4). In the hypertension group, 25.6% patients had the total cholesterol >=6.2 mmol/L, significantly higher than those in the nonhypertension group (p< 0.05), and the prevalence of abnormal level of LDL-C and ApoB increased with the grade of CRF. Patients with grade III of hypertension had severe dyslipidemia: hypercholesterolemia, hyperglyceridemia, increased LDL-C and ApoB, and CT-HDL-C ratio >5. Among them, 92.1% had lipoprotein disorders. Conclusion: Increased total cholesterol accounted for 25.6% patients of hypertension group. Prevalence of patients with disorders of LDL-C and ApoB were high in hypertension group, and increased with the grade of CRF. Lipoprotein disorders were increased with the grade of hypertension.

The author studied 104 renal arteries of healthy people and 106 renal arteries of hypertension patients by color Duplex ultrasound and DSA, and then compared these findings. Results: color Duplex ultrasound can detect 96% of renal arteries. Ultrasound can be used to study renal arteries with 3 positions gave high rate of detection: anterior abdominal position 96%, right subcostal position 94%, and translumbar position 98%

Renal hypoplasia is defined as a subnormal growth of the kidney with a distinct cortex and medulla and is recognizable as a kidney. It is known that renal hypoplasia can induce hypertension by reduction of functioning nephron. Patients with reduced functioning renal mass by surgical or medical causes have a risk to develop hypertension. Patients with congenital reduction of functioning nephron have more frequently showed renal insufficiency. But renal hypoplasia induced hypertension is very rare and reported rarely in international literature. We report two cases of hypertension associated with congenital renal hypoplasia.
