Case ReportsTransvenous approach to salvage incomplete arterial embolization of compound traumatic arteriovenous fistulae.
Two patients with compound arteriovenous fistulae, in whom transarterial embolizations failed, were managed by embolization of the arterial tributaries of their fistulae from retrograde, transvenous access. Transvenous embolizations were successful in both patients. Given multiple arterial tributaries, and large communicating hematomas into which these arteries bleed, transvenous access may be a useful approach for embolizing compound traumatic arteriovenous fistulae.

To describe the spectrum of radiologic findings in crutch-induced axillary artery injury and the effects of its unique pathophysiology on diagnostic evaluation and treatment. ⋯ Chronic axillary crutch use may be associated with axillary artery stenosis, aneurysm formation, and secondary axillobrachial thromboembolic disease. Mural injury can be successfully treated by PTA and thromboembolic disease by thrombolytic therapy. Early identification of the axillary artery lesion is critical for long-term therapeutic results.

Embolization of renal vascular lesions: clinical experience with microcoils and tracker catheters.
After biopsy (n = 6) and nephrostomy (n = 1) of three native and four transplanted kidneys, gross hematuria, hypertension, and deterioration of function necessitated performance of transarterial embolization. Angiography revealed five arteriovenous fistulas (AVFs), one pseudoaneurysm, and one arteriocaliceal fistula. Superselective catheterization was accomplished using 5 Fr standard diagnostic catheters and 3 Fr coaxial Tracker catheters. ⋯ Embolization stopped the bleeding in all patients. One week after treatment, renal function was improved in 5 patients and remained unaffected in 2. Superselective embolization using Tracker catheters and fibered microcoils is an effective, safe treatment of renal vascular lesions.

Case ReportsDelayed hemorrhage following transcatheter arterial embolization for blunt hepatic injury.
This is the first report of delayed hemorrhage (21 days after the injury) following transcatheter arterial embolization (TAE) for severe hepatic injury. The first TAE was performed about 2 h after admission on a 21-year-old man with severe blunt hepatic injury. Three bilomas were detected by cholescintigraphy 19 days later. ⋯ Angiography was repeated and three pseudoaneurysms were detected in the same areas as the bilomas. With repeated TAE, pseudoaneurysms disappeared and hemorrhage could be controlled. Intrahepatic biloma may be related to pseudoaneurysms and delayed hemorrhage in severe hepatic injury.
