ABSTRACT
OBJECTIVES: Mesenteric ischemia is uncommon in the general population but is frequently encountered in chronic hemodialysis patients. We present here four cases which occurred in our unit within one year while only six cases had been observed in the preceding twenty years. OBSERVATIONS: Four chronic hemodialysis patients (age: 57 to 76 years) with renal failure due to diffuse atheromatous disease, presented non-occlusive mesenteric ischemia. One patient died and one underwent resection of the colon. For the final two patients, prophylactic therapy was initiated. DISCUSSION: Mesenteric ischemia is a severe condition which appears to occur more frequently in end-stage renal disease. In the chronic hemodialysis patient excessive ultrafiltration or a too rapid filtration rate can favor ischemia. Prophylactic measures must be taken at the first sign of ischemia, especially since clinical and biological features of mesenteric ischemia remain largely non-specific.

In this work, we looked at the results of a retrospective study carried out in our unit on the ocular manifestations in the dialysed chronic renal failure patient. Eighty-one of our 189 patients had an ophtalmic examination. Thirty-six showed a retinopathy, 26 suffered from a corneoconjunctival alterations, 19 from a cataract, 6 a vascular thrombosis, 4 a glaucoma and one motor-ocular paralysis. There was no significant difference for age and sex between the 81 patients and the group of 108 who did not have an ophtalmic examination. But this difference was positive for duration of time on dialysis (p = 0.01). There is a correlation between the presence of a cataract and the age of the patients (p = 0.01). There was no link between the different types of ophtalmic problems on the one hand, and the age, sex, time on dialysis, type of dialysis, original nephropathy, hypertensive history or anterior renal transplantation on the other hand.
