Abstract

Objective:

To evaluate dialysis history, imaging findings and outcome of endovascular treatment in six patients with central venous stenosis without a history of previous catheter placement.

Material and methods:

Between April 2000 and June 2004, six (10%) of 57 haemodialysis patients had stenosis of a central vein without a previous central catheter placement. Venography findings and outcome of endovascular treatment in these six patients were retrospectively evaluated. Patients were three women (50%) and three men aged 32–60 years (mean age: 45 years) and all had massive arm swelling as the main complaint. The vascular accesses were located at the elbow in five patients and at the wrist in one patient.

Results:

Three patients had stenosis of the left subclavian vein and three patients had stenosis of the left brachiocephalic vein. The mean duration of the vascular accesses from the time of creation was 25.1 months. Flow volumes of the vascular access were very high in four patients who had flow volume measurement. The mean flow volume was 2347 ml/min. One of three patients with brachiocephalic vein stenosis had compression of the vein by the brachiocephalic artery. All the lesions were first treated with balloon angioplasty and two patients required stent placement on long term. Number of interventions ranged from 1 to 4 (mean: 2.1). Symptoms resolved in five patients and improved in one patient who had a stent placed in the left BCV.

Conclusion:

Central venous stenosis in haemodialysis patients without a history of central venous catheterization tends to occur or be manifested in patients with a proximal permanent vascular access with high flow rates. Balloon angioplasty with or without stent placement offers good secondary patency rates in mid-term.

Introduction

Central venous stenosis or occlusion is a serious complication in haemodialysis patients and is mostly secondary to trauma caused by temporary or permanent haemodialysis catheter placement. Central vein stenosis is much more common when the subclavian vein (SCV) rather than the internal jugular vein is used for catheterization and SCV catheterization should be abandoned [1]. Central vein stenosis may cause swelling of the arm, which may preclude cannulation of the arm veins during haemodialysis, and may cause increased rates of recirculation. It may also cause difficulties for the future placement of temporary or permanent central venous catheters.

Although rare, central venous stenosis or occlusion may also develop without a history of previous central venous catheter placement [1], [2]. The exact mechanism leading to stenosis in these patients is unknown and there are very few case reports in the literature. We report detailed haemodialysis history, imaging findings and outcome of endovascular treatment in six patients who developed central venous stenosis without a previous catheter placement.

Materials and methods

Between April 2000 and June 2004, 57 haemodialysis patients with stenosis or occlusion of a central vein ipsilateral to a functioning permanent vascular access were treated with endovascular balloon angioplasty with or without stent placement in our university hospital. The stenosis/occlusion was on the right in 27 (47%) patients, on the left in 29 (51%) patients and in the superior vena cava in one (2%) patient. Six of 57 patients (10%) with central vein stenosis ipsilateral to the functioning

Results

The degree of stenosis was 60% in one patient and greater than 70% in other five patients. Three patients had stenosis of the left subclavian vein and three patients had stenosis of the left brachiocephalic vein (Fig. 1). Lesion length ranged from 1 to 4 cm. All six patients with stenosis or occlusion of a central vein have had a functioning vascular access without acute thrombus in any of the vessels from the arteriovenous anastomosis to the superior vena cava. The duration of the vascular

Discussion

All six patients in our study group had stenosis of the central veins on the left side and all of them had a vascular access with very high flow volumes. Another common feature in five of six patients was elbow location of the vascular access with brachiocephalic AVF in four patients and brachioaxillary AVG in one patient. AVGs in general and AVFs located around elbow have higher flow volumes when compared to distal Brescia–Cimino type AVFs. The only patient with a wrist level Brescia–Cimino

Conclusion

Central venous stenosis ipsilateral to the functioning vascular access in haemodialysis patients without a history of central venous catheterization is not very infrequent. It comprised one-tenth of central venous stenosis in our patient population. The lesions tend to occur in patients with a proximal permanent vascular access like elbow AVF or AVG with very high flow rates. Endovascular treatment with balloon angioplasty with or without stent placement offers good secondary patency rates in
