The number of cases of superior vena cava syndrome (SVCS) increased due to increased cardiac devices and central venous catheters. Management of benign SVCS is still controversial. A 51-year-old male known to have ischemic cardiomyopathy and chronic renal failure on regular hemodialysis. In the last 12 months, he had progressive shortness of breath and swelling of his upper part of the body. Examination revealed engorgement of the neck veins, facial puffiness, and pitting edema of both upper limbs. Venography showed occluded SVC. We applied a 50 Watt of energy via electrocautery pen to a Hi-Torque 0.014 Astato guidewire to cross the occluded segment retrogradely. We used 2 stents 39 mm, mounted on BIB 20/40 mm. Final angiography revealed full restoration of SVC flow. Diathermy use to cross a chronic total SVC obstruction is feasible and safe. Endovascular techniques are suitable as initial management of benign SVC syndrome.
