1 Endovascular Therapy for Acute Trauma: A Pictorial Review
Anirudh Mirakhur, MD, Richard Cormack, MD, Muneer Eesa, MD, FRCPC, Jason K. Wong, MD, FRCPC  Canadian Association of Radiologists Journal  Volume 65, Issue 2, Pages (May 2014) DOI: /j.carj Copyright © 2014 Canadian Association of Radiologists Terms and Conditions

2 Figure 1 (A) Gelfoam. (B) Intra-arterial coils. (C) Intra-arterial Amplatzer plug. (D) Intra-arterial stent. This figure is available in colour online at Canadian Association of Radiologists Journal  , DOI: ( /j.carj ) Copyright © 2014 Canadian Association of Radiologists Terms and Conditions

3 Figure 2 Traumatic carotid pseudoaneurysm. (A) Single-axial computed tomographic angiogram image of the neck, demonstrating a large pseudoaneurysm (arrow) arising off the medial wall of the right internal carotid artery (ICA) (B) Digital subtraction angiography (DSA) image, demonstrating the same large pseudoaneurysm (arrow). (C) DSA image, demonstrating a stent graft (arrows) in the high cervical ICA with complete exclusion of the pseudoaneurysm; note the poststent vasospasm. (D) Facial radiograph with the stent graft (arrows) in situ. CCA = common carotid artery.

4 Figure 3 Traumatic carotid-cavernous fistula (CCF). (A, B) Selected axial computed tomographic angiogram images, demonstrating asymmetric early filling of the left cavernous sinus (CS) (short arrow in [A]) and dilated left superior ophthalmic vein (SOV) (long arrow in [B]). (C) Digital subtraction angiography (DSA) image, demonstrating a direct fistulous communication between the cavernous internal carotid artery (ICA) and the CS (arrow) as well as retrograde filling into prominent left SOV and left internal jugular (IJ) vein. (D) Transarterial approach with detachable balloons failed; subsequently, a transvenous approach through the left IJ vein and inferior petrosal sinus resulted in successful coiling (arrow) of the CS and complete occlusion of the CCF; note the partial occlusion of the cavernous ICA; however, the patient had no clinical sequelae due to good intracranial collateral flow.

5 Figure 4 Traumatic subclavian arterial pseudoaneurysm and arteriovenous (AV) shunt. (A) Single axial computed tomographic angiogram (CTA) image, demonstrating a large mediastinal hematoma (H) with an area of large extravasation at the left subclavian artery with pseudoaneurysm formation (circle) at the left subclavian artery (LSCA) origin; note the early filling of the left brachiocephalic vein (LBCV) (arrow) secondary to a fistulous communication with the LSCA. (B) Arch aortogram, demonstrating a large pseudoaneurysm immediately distal to the LSCA (short arrow) origin (circle) as well as an AV shunt between the proximal LSCA and LBCV (long arrow), and early filling of the superior vena cava. (C, D) Digital subtraction angiography and CTA images after stent-graft placement (arrows), with complete exclusion of the pseudoaneurysm.

6 Figure 5 Traumatic pulmonary artery pseudoaneurysm. (A) A single digital subtraction angiography (DSA) image, demonstrating a large pseudoaneurysm (arrow) arising off a segmental branch of the right pulmonary artery. (B) Single DSA image, demonstrating no flow to the pseudoaneurysm after placement of Amplatzer vascular plugs in the pseudoaneurysm neck and the segmental pulmonary arterial branch.

7 Figure 6 Acute thoracic aortic injury. (A, B) Selected axial computed tomographic angiogram images, demonstrating a descending aortic arch pseudoaneurysm with an intraluminal flap (arrow) extending from just inferior to the left subclavian artery (not visualized) to the level of the left main pulmonary vein (not visualized). (C) A single digital subtraction angiography image, demonstrating successful occlusion of the pseudoaneurysm with a stent graft deployed just distal to the left common carotid artery with intentional coverage of the left subclavian artery (for adequate proximal landing zone coverage).

8 Figure 7 Traumatic splenic laceration. (A) A single computed tomographic angiogram image, demonstrating a splenic laceration (arrow) with irregular hyperdensity along the margin of the splenic parenchyma, consistent with active extravasation. (B) Active extravasation (arrows) from splenic arterial branches on the digital subtraction angiography image. (C) Coils (c) in the main splenic artery, and 2 divisions of the lower splenic arterial branch with persistent flow in the splenic arterial system. (D) Complete cessation of flow after Gelfoam augmentation (arrow) of the coil mass.

9 Figure 8 Delayed traumatic hepatic arteriovenous (AV) fistula. (A–C) Selected computed tomographic angiogram images, demonstrating a left hepatic arterial (LHA) (short arrow) branch pseudoaneurysm (circles) with an associated AV fistula as the middle hepatic vein (MHV) fills in the arterial phase. Previous coils (rectangles) within the branch of the right hepatic artery related to previous embolization. (D) Digital subtraction angiography image, demonstrating the pseudoaneurysm (arrow) and the AV fistula. (E) Successful coil embolization (arrows) of the branch of the LHA feeding the pseudoaneurysm–AV fistula.

10 Figure 9 Traumatic renal injury in a patient with incidental angiomyolipomas. (A, B) A single computed tomographic angiogram (CTA) image, demonstrating active contrast extravasation (circle) from right renal laceration; note multiple angiomyolipomas (arrows) in both kidneys. (C) Single digital subtraction angiography (DSA) image, demonstrating active contrast extravasation (short arrow) and multiple angiomyolipomas (long arrows). RRA = right renal artery. (D) Post–coil embolization (arrow) DSA image, showing complete hemostasis with no further extravasation.

11 Figure 10 Traumatic “pseudo” May-Thurner syndrome. (A) A single computed tomographic angiogram image, demonstrating an ovoid hyperdensity (arrow) medial to the distal left common iliac artery, consistent with active extravasation from a left common iliac venous injury; note the surrounding retroperitoneal hematoma. (B) A left iliac venogram, demonstrating focal active contrast extravasation of the left common iliac vein near the origin of the left internal iliac vein. In addition, there is a mass effect on the left common iliac vein (arrow) from the regional hematoma, which resulted in May-Thurner–like physiology. (C) Post–stent graft (arrows) placement venogram, demonstrating no further extravasation with improved flow through the left iliac veins.

12 Figure 11 Pelvic trauma and arterial extravasation. (A) Pelvic radiograph, demonstrating an open-book fracture. (B) A single digital subtraction angiography image, demonstrating a large focus of active contrast extravasation (circle) that involves the left internal iliac artery. Multiple other foci of contrast extravasation (arrows) are noted that involve the left internal iliac artery. Note the intense vasospasm that involves the right external iliac and left common iliac arteries secondary to shock. (C) Coil embolization (arrow) of right internal iliac artery. The proximal left internal iliac artery was embolized with Gelfoam (not shown).

13 Figure 12 Traumatic arteriovenous (AV) fistula of a muscular branch of the right profunda femoral artery. (A) A single digital subtraction angiography image, demonstrating an AV fistula (circle) between a muscular branch of the profunda femoris and the adjacent superficial femoral vein (arrow). At the point of communication, there is an irregular false aneurysm. (B) Complete occlusion of the feeding vessel and the AV fistula was accomplished with controlled release coil embolization (arrow).
