Background: Patients with chronic kidney disease on chronic hemodialysis develop disabling complications associated with vascular access, especially central venous stenosis and occlusion. Objective: Describe the results of venography among patients undergoing chronic hemodialysis and their subsequent management at Hospital Cayetano Heredia. Materials and Methods: Retrospective case series study involving 91 chronic kidney disease patients undergoing chronic hemodialysis who underwent 115 venography procedures at Hospital Cayetano Heredia. The clinical-demographic characteristics, type, number and location of vascular accesses, indications, venography results and subsequent management were evaluated. An exploratory analysis was conducted on variables possibly associated with the venographic diagnosis. Results: The average age was 51.7 (SD ± 15.8) years, 48 (52.7%) were females. The central venous system was reported to be permeable in 40 (34.8%) venographies, with stenosis in 27 (23.5%) and with occlusion in 48 (41.7%). The main subsequent management involved the creation of a new vascular access in 79 (68.7%) patients, with the non-tunneled catheter being the most placed in 40 (50.6%). Chronic hemodialysis duration, the number of previous vascular accesses and the number of previous cervical catheters, particularly non-tunneled catheters and those placed in jugular veins, were related with a higher probability of stenosis and occlusion of the thoracic central venous system. Conclusions: Central venous stenosis and occlusion were the most frequent venographic results. The non-tunneled catheter represented the main subsequent management choice, the greatest number of which was identified as the predominant factor related to these events.
