Summary

The purpose of our study is to compare physical examination alone to color Doppler ultrasonography (CDUS) vascular mapping and physical examination in terms of outcomes of vascular access and long-term patency.

Conditions

Interventions

PROCEDURE

preoperative color Doppler ultrasonographic vascular mapping

Preoperative color Doppler ultrasonographic vascular mapping was performed with linear probe. The patient extremity under scrutiny was placed under support, with tourniquet augmentation. Vessels were examined in both short (transverse) and long (longitudinal) axis. Anatomical variations, wall morphology and internal diameters at the antecubital fossa, the proximal (cranial), mid and distal (caudal) third of the arm and forearm were assessed in both extremities. Veins were evaluated for compressibility and adequate drainage to deep venous system. The presence of sclerotic, thrombosed and fibrosed segments were noted. Doppler waveforms were obtained in the long axis and volume flow (VF) calculated for arteries selected for potential access construction.

PROCEDURE

physical examination

Arterial pulse examination, differential blood pressure measurements and the Allen test in both extremities. Inspection of the superficial venous system with tourniquet enhancement in the arm was performed during venous assessment.

PROCEDURE

medical history

medical history with respects to diabetes mellitus, coronary heart disease, peripheral vascular disease

PROCEDURE

native arteriovenous fistula construction

surgigal creation of native arterial and venous anastomoses

PROCEDURE

arteriovenous graft placement

surgical placement of arteriovenous graft
