Vein rupture by Arrow-Trerotola percutaneous thrombolytic device in a treatment of thrombosed arteriovenous graft

Introduction: We report a case of vein rupture by Arrow-Trerotola percutaneous thrombolytic device (Trerotola PTD) during a treatment of thrombosed arteriovenous graft (AVG). Case Description: A 77-year-old woman with a problem of thrombosed AVG underwent an endovascular treatment including a procedure of angioplasty of axillary vein. After angioplasty of axillary vein, we found a newly developed thrombus in axillary vein and performed thrombolysis using an over-the-wire 7F Trerotola PTD. When the rotating cage of the device arrived at axillary vein, it suddenly stopped, fixed at the angioplasty site, and didn’t move at all. Venogram showed an extravasation of contrast media at axillary vein, suggesting vein rupture. The patient underwent an emergency operation. Conclusions: It could be dangerous to use Trerotola PTD in a native vein immediately after angioplasty.

Compartment Syndrome of the Upper Extremity Induced by Extravasation of Contrast Media after Computed Tomography: A Case Report

The incidence of contrast media extravasation has been increasing gradually. Most contrast media extravasations only can cause pain, swelling and erythema. However, in more severe cases, skin necrosis, ulceration, or compartment syndrome may occur, often necessitating a surgery. Early diagnosis and treatment should be established on the spot in order to avoid such a severe damage. We present a case of 42-year-old woman with a compartment syndrome in the right upper extremity caused by extravasation of computed tomography contrast media.
