ABSTRACT Fibrotic central venous occlusions in patients with thoracic malignancy and prior radiotherapy can be impassable with standard catheters and wires, including the trailing or stiff end of a hydrophilic wire. We report two patients with superior vena cava syndrome in whom we successfully utilized a radiofrequency guide wire (PowerWire, Baylis Medical, Montreal, Quebec, Canada) to perforate through the occlusion and recanalize the occluded segment to alleviate symptoms.

    ABSTRACT: We describe a case of successful recanalization of a longstanding right common iliac occlusion with a radiofrequency (RF) guidewire. The patient had been symptomatic with claudication for 3 years, and a preliminary attempt to cross the lesion using conventional techniques proved unsuccessful. Using low and medium intensity RF pulses and a PowerWire, a tract through the occlusion was established, which allowed subsequent stenting with an excellent angiographic result and a good immediate clinical response. We propose this as a useful technique in the peripheral arterial system for occlusive lesions not amenable to traditional recanalization techniques.

    ABSTRACT: Superior vena cava syndrome results from the obstruction of blood flow through the superior vena cava and is most often due to thoracic malignancy. However, benign etiologies are on the rise secondary to more frequent use of intravascular devices such as central venous catheters and pacemakers. Although rarely a medical emergency, the symptoms can be alarming, particularly to the patient. Traditionally, superior vena cava syndrome has been managed with radiotherapy and chemotherapy. But interventional endovascular techniques have made inroads that offer a safe, rapid, and durable response. In many cases, it may be the only reasonable treatment. Because of this, an approach to endovascular treatment of this condition must be in the armamentarium of the interventional radiologist. This review will provide the reader with an insight into the etiology, pathophysiology, and various management principles of superior vena cava syndrome. The focus will be on understanding the techniques used during various endovascular interventions, including angioplasty, stenting, and pharmacomechanical thrombolysis. Discussion will also be centered on possible complications and current evidence as well as controversies regarding these approaches.
