Figure 4. Coronal CT image obtained 6 weeks after CERAB shows a decrease in size of the aneurysm with a concomitant decrease in the size of the phlegmon. Glue fragmentation was noted. Vessels with stents were widely patent, and the aneurysm was completely thrombosed with no endoleak (compare with Fig 1).

Editor: We present a case of an arteriovenous fistula (AVF) of the external iliac vessels following endovenous laser treatment (EVLT) of varicose veins that was successfully treated with an AMPLATZER Duct Occluder II (St. Jude Medical, Inc, St. Paul, Minnesota) after an unsuccessful attempt at surgical ligation. Our institution does not require institutional review board approval for case reports. A 62-year-old man presented to his family physician with a 4-year history of gradually worsening dyspnea. He had undergone EVLT for greater saphenous vein varicosities 4 years before presentation, at which time a venous ultrasound scan did not demonstrate a fistula. Computed tomography angiography revealed a 12-mmwide AVF between the left external iliac artery and vein with associated dilatation of the common femoral vein and IVC (Figs 1, 2). Echocardiography confirmed left ventricular hypertrophy likely secondary to high-output cardiac failure from the AVF. Because of the width of the AVF (12 mm), the patient underwent surgical repair and began a course of warfarin to prevent thrombus development in the dilated veins, which would no longer be exposed to high-flow blood. The patientʼs dyspnea returned 12 months after surgery, and repeat computed tomography angiography showed the AVF had reopened. Because of the difficult initial surgery and failure of surgical ligation, it was decided to perform an endovascular approach. The width of the AVF measured 3 mm, the external iliac vein measured 20 mm, and the external iliac artery measured 10 mm at the level of the fistula. These measurements were compatible with an AMPLATZER Duct Occluder II device. The procedure was performed under local anesthesia and conscious sedation. Venous and arterial access was obtained to deploy the device over a secure wire using the “body floss” technique for through-and-through access. The distal left common femoral artery was accessed retrogradely followed by insertion of a 6-F vascular sheath, and the right femoral vein was accessed retrogradely followed by insertion of a 7-F vascular sheath. A 0.035-inch angled hydrophilic guidewire was advanced from the arterial side into the inferior vena cava through the fistula and snared for through-and-through access with an Ensnare device (Merit Medical; South Jordan, Utah). Through the venous access site, the AMPLATZER Duct Occluder II (diameter

A completion arteriogram demonstrated no residual AVF (Fig 4). At 18 months after the procedure, the patient was asymptomatic, and vascular ultrasound demonstrated trace AVF flow (Fig 5) with no dilated veins and no palpable bruit. AVF formation is a rare complication of EVLT for varicose veins (1,2). We believed that an external iliac artery stent graft not only would be at increased risk of migration, thrombosis, and fracture but also would likely

require a surgical cutdown for deployment. Chaudry et al (3) described deployment of an AMPLATZER II plug via a surgical cutdown for a posttraumatic AVF between the profunda femoris artery and vein 30 years after a gunshot injury, but the low profiling of the AMPLATZER Duct Occluder II was thought to be a more suitable option to reduce the likelihood of thrombosis. Ultrasound-guided compression was also discussed, but given the paucity of

data in the literature supporting this method, it was decided to proceed with an endovascular option. We describe successful treatment of an external iliac AVF with a ductus arteriosus occluder device traditionally used to treat patent ductus arteriosus, and this experience presents an interesting solution to a rare complication of EVLT. Given the low profiling of the device within the vessels, the risk of potential thrombosis was thought to be minimal. Finally, given its low migration rate (4), the AMPLATZER Duct Occluder II was viewed as a safe option for treating this fistula.

Editor: This report meets criteria for institutional review board exemption at our institute. We present a case of type I aortic dissection (DeBakey classification) with concomitant pulmonary artery (PA) dissection extending through a patent ductus arteriosus (PDA), which was definitively diagnosed by multidetector computed tomography (CT). A 42-year-old woman presented with episodic dyspnea, coughing, shortness of breath, and nocturnal orthopnea. The patient denied a history of trauma or surgery. However, she reported a past medical history of PDA, which was detected by transthoracic echocardiography 5 years ago and was not treated. The physical examination showed a systemic arterial pressure of 126/ 59 mm Hg. A grade 3/6 systolic murmur was heard in the precordial region. Transthoracic echocardiography showed the aorta and PA dissection, left atrium, and left ventricular enlargement. A PDA that connected the main PA with the descending aorta was detected (Fig 1). Chest radiography demonstrated superior mediastinum broadening, severe cardiomegaly,
