We present a case of developmental venous anomaly associated with arteriovenous fistula supplied by a single arterial feeder adjacent to a large acute intracerebral hemorrhage. The arteriovenous fistula was successfully obliterated by superselective embolization while completely preserving the developmental venous anomaly. Two similar cases, including superselective angiographic findings, have been reported in the literature; however, we describe herein superselective angiographic findings in more detail and demonstrate the arteriovenous shunt more clearly than the previous reports. In addition, a literature review was performed to discuss the association of a developmental venous anomaly with vascular lesions.

An endovascular intervention is a feasible alternative to the technically challenging conventional surgery for the treatment of traumatic vertebral arterial lesions. This report describes a rare case involving a 22-year-old patient with a traumatic vertebral arterial pseudoaneurysm and multiple arteriovenous fistulas which were successfully sealed using the endovascular stent-graft technique.

This report concerns a 4-month-old infant with progressive prominent and redness of his left eye since birth. This report concerns a 4-month-old infant with progressive prominent redness of his left eye since birth. Angiography revealed a congenital pial arteriovenous fistula between the temporal branch of the left posterior cerebral artery and left cavernous sinus through the sphenoparietal sinus, a condition not reported in the literature. The fistula was successfully occluded with two micro-coils by vertebrobasilar approach.

4.Diagnosis and Management of Congenital Coronary Arteriovenous Fistula in the Pediatric Patients Presenting Congestive Heart Failure and Myocardial Ischemia.
Yonsei Medical Journal 2009;50(1):95-104
PURPOSE: Four pediatric patients with congenital coronary arteriovenous fistula (CAVF) were reported to remind pediatric practitioners and cardiologists of its diagnosis and management. MATERIALS AND METHODS: Four pediatric patients with congenital CAVF from June 1999 to November 2007 were included in this retrospective study. Study modalities included reviews of patients' profiles of clinical features, chest radiograph, Doppler echocardiography, cardiac catheterization with angiography, myocardial perfusion scan, and computed tomography. RESULTS: All 4 patients were symptomatic. The clinical symptoms and signs were feeding problem, continuous murmur, tachycardia, tachypnea, cardiomegaly, and exertional chest pain. Myocardial enzyme was elevated in 1 patient. Echocardiography showed dilatation of the coronary artery in all 4 patients, and traced down its origin in 3 and drainage in 4. The fistulas originated from the right coronary artery in 2 patients and left coronary artery in 2, and were drained into the right ventricle in 2, right atrium in 1, and pulmonary artery in 1. Single left coronary artery was found in 1 patient. The pulmonary-to-systemic blood flow ratios ranged from 1.2 to 2.5. Transcatheter coil occlusion was successfully performed in 4 patients through a coaxial delivery system. The symptoms and signs of congestive heart failure and myocardial ischemia disappeared after the procedure. CONCLUSION: Diagnosis of congenital CAVF could be achieved by appreciation of continuous murmur over area unusual for the ductus, and by scrupulous examination of echocardiography as well as angiography of the coronary artery through which coaxial transcatheter coil occlusion could be performed successfully.

Arthroscopic meniscectomy of the knee is generally a safe and effective procedure with a low rate of vascular complications. We report here on a unique case of a 55-year-old man with a lateral inferior genicular artery pseudoaneurysm and a concomitant arteriovenous fistula that developed after arthroscopic meniscectomy; this was successfully treated with selective angiographic embolization. This case illustrates the effectiveness of an endovascular approach as a minimally invasive treatment for this uncommon complication that occurs after an arthroscopic procedure.

We present a case of a patient with rapid deterioration of esophageal varices caused by portal hypertension accompanied by a large arterioportal shunt that developed after radiofrequency ablation of hepatocellular carcinoma. We used n-butyl cyanoacrylate (NBCA) as an embolic material to achieve pinpoint embolization of the shunt, because the microcatheter tip was 2 cm away from the shunt site. Under hepatic arterial flow control using a balloon catheter, the arterioportal shunt was successfully embolized with NBCA, which caused an improvement in the esophageal varices.

OBJECTIVETo evaluate the efficacy and safety of the interventional techniques in the treatment of renal vascular injury.
METHODSA total of 16 patients with renal vascular injuries were treated by superselective arterial embolization. The renal injuries resulted from renal biopsy in 7 patients, endovascular intervention in 2, percutaneous puncture and pyelostomy in 2, local resection of renal tumor in 1 and trauma in 4. With regards to clinical manifestations, there was hemorrhagic shock in 8 patients, severe flank pain in 14, and hematuria in 14. CT and ultrasonography confirmed that 15 patients had perirenal hematoma. The embolization was performed with microcoils in 13 and standard stainless steel coils in 3 patients, associated with polyvinyl alcohol particles (PVA) in 9, and gelfoam particles in 6 cases.
RESULTSRenal angiogram revealed arteriovenous fistula in renal parenchyma in 9 cases, pseudoaneurysm in 3 and extravasation of contrast media in 4. The arterial embolization was successful in all 16 cases in a single session. The angiography at the end of therapy showed that abnormal vessels had disappeared without other major intrarenal arterial branch occlusion. In 13 patients with hemodynamical compromise, blood loss-related symptoms were immediately relieved after blood transfusion. In 14 patients with severe flank pain, the pain was progressively relieved. Hematuria ceased in 14 patients 2-14 days after the embolization procedures. The renal function was impaired after the procedure in 6 cases, in which preoperative renal insufficiency was exacerbated in 3 and developed new renal dysfunction in 3, 2 of whom received hemodialysis. The ultrasonography showed that perirenal hematoma was gradually absorbed within 2-6 months after the procedure. All patients were followed up in 6-78 months (mean, 48 months). Six patients died of primary diseases (5 cases of renal failure and multiple organ failure and 1 case of malignant tumor). Ten patients survived without bleeding and further intervention. The deterioration of renal function did not occur and the serum creatinine and blood urea were in normal range.
CONCLUSIONTranscatheter selective renal arterial embolization is a safe and effective method in the treatment of renal vascular injuries.
