Doctors clear 3cm vein blockage in dialysis patient, saving limb and face

A 62-year-old dialysis patient in Taiwan faced a critical health crisis when a completely blocked central vein led to severe swelling in his right arm and right side of his face. The blockage severely impeded blood flow, causing a dangerous backup in his upper body and jeopardizing his essential dialysis access.

Seeking treatment at Yuanrong Hospital in Changhua, the patient was diagnosed with a complete obstruction of his innominate vein, in addition to peripheral vascular stenosis. This condition prevented blood from the arteriovenous fistula, crucial for hemodialysis, from returning to the heart efficiently. Doctors noted that such blockages not only hinder dialysis effectiveness but can also pose life-threatening risks.

The patient's right arm was abnormally swollen, and even the right side of his face was swollen. This situation stemmed from severe problems with central venous return.

While percutaneous transluminal angioplasty (PTA) with a small incision is a common treatment, this patient's blockage was entirely occluded, making standard entry impossible. The medical team, led by Dr. Lai Jin-hu, chief of cardiac surgery, devised an alternative strategy. They accessed the vein through the patient's right neck, carefully navigating a guidewire through the 3-centimeter blockage.

Facing this 'dead end,' the medical team decided to change strategies. Normally, treatment uses percutaneous transluminal angioplasty (PTA), with an incision of only about 2 millimeters, using a guidewire to cross the narrowed area and then expanding the blood vessel with a balloon catheter. But this patient's blockage was completely occluded, making it impossible to enter from the original dialysis access.

Using a specialized micro-guidewire and closely monitoring its path to avoid puncturing the vessel wall, the team successfully cleared the obstruction. They then used balloons of 3mm and 10mm to gradually expand the vein, restoring normal blood flow. A week after the procedure, the patient's swelling had significantly decreased, and his dialysis access was functioning normally, averting the risk of needing new vascular access surgery.

Dr. Lai emphasized the importance of early assessment for dialysis patients experiencing symptoms like limb swelling, decreased dialysis flow, weakened fistula tremors, recurrent bleeding, or facial puffiness. Prompt medical attention can prevent such severe complications.

If dialysis patients experience hand swelling, decreased dialysis flow, weakened fistula tremors, recurrent bleeding, or facial puffiness, they should seek vascular assessment as soon as possible and not delay.
