Abstract

Purpose: Intravascular stents have become important tools for the management of vascular lesions; however, stents in combination with vascular grafts have only recently reached clinical application. This report describes an experience with stented grafts for the treatment of penetrating arterial trauma. Methods: Seven transluminally placed stented grafts were used to treat one arteriovenous fistula and six pseudoaneurysms. These grafts were successfully inserted percutaneously or through open arteriotomies that were remote from the site of vascular trauma. The devices were composed of balloon-expandable stainless steel stents covered with polytetrafluoroethylene grafts. Results: Patency up to 14 months was achieved (mean follow-up 6.5 months) with these stented grafts. The use of stented grafts appears to be associated with decreased blood loss, a less invasive insertion procedure, reduced requirements for anesthesia, and a limited need for an extensive dissection in the traumatized field. These advantages are particularly important in patients with central arteriovenous fistulas or false aneurysms who are critically ill from other coexisting injuries or medical comorbidities. Conclusions: The use of stented grafts already appears justified to treat traumatic arterial lesions in critically ill patients. Although the early results with the seven cases in this report are encouraging, documentation of long-term effectiveness must be obtained before these devices can be recommended for widespread or generalized use in the treatment of major arterial injuries.

PATIENTS AND METHODS

Seven endovascular stented graft repairs of traumatic arterial lesions were performed in seven patients at Montefiore Medical Center in New York over a 14-month period. Details regarding the injury and the endovascular repair in the seven patients are presented in Table I.Informed consent for the placement of a stent graft device was obtained from each patient. All procedures were performed under fluoroscopic guidance in the operating room with the patient prepared for a standard surgical

RESULTS

As shown in Table I, seven patients received seven stented grafts to treat traumatic arterial lesions. The mean age of the patients was 41 years (range 20 to 78). Six patients were men. Four injuries occurred as a result of gunshot wounds (Fig. 2).

DISCUSSION

Prompt diagnosis and treatment of penetrating vascular trauma are required to avoid the late sequelae that may occur when important injuries are not appropriately treated. 10, 11, 12, 13 Traumatic arteriovenous fistulas and pseudoaneurysms involving nonessential vessels, such as branches of the hypogastric or deep femoral arteries, have been effectively treated by catheter-directed arterial embolization. 14, 15 Injuries to vital arteries have uniformly required direct surgical repair of the
