Transplant renal artery stenosis [TRAS] and systemic hypertension in renal allograft recipients

ABSTRACT

One hundred and forty renal allograft recipients were included in this study, 24 had end to side vascular anastomosis to the external iliac artery or common iliac artery and 116 patients had end to end vascular anastomosis. The incidence of TRAS was similar in both groups. Out of successful 123 angiographic exposure, 29 patients [236%] were normotensive. Severe hypertension was noticed in about half of the patients with TRAS. A highly significant negative correlation between the grade of graft perfusion and the severity of hypertension was noticed in hypertensive with TRAS, on the other hand, normotensives with TRAS showed good graft perfusion. In this work, 82.8% of TRAS were at anastomosis and 10.3% showed kink stenosis. Erythrocytosis was found to be associated with TRAS but was not a constant finding and not statistically significant. Comparison of the kidney function, plasma renin activity and plasma aldosteron concentration for patients with and without TRAS showed no significant difference
