Embolization of Anterior Communicating Aneurysm associated with Interrupted Aortic Arch / 신경중재치료의학

Interrupted aortic arch (IAA) is an interruption in the continuity of the aortic arch, often with a fibrous cord between the two segments. It accounts for about 1% of congenital cardiovascular defects and is differentiated from severe coarctation and aortic atresia by the absence of any structural connection (1). Survival may be prolonged because effective arterial collaterals to the descending aorta develop during fetal and postnatal life (2). Although only two cases reported a combination between IAA and an aneurysm of the circle of Willis, there is none of report in coil embolization of the same case. We describe a 31-year-old patient, in whom IAA and unruptured aneurysm were discovered during angiography. Coil embolization was performed via direct puncture of the common carotid artery, which was required due to arterial tortousity and interruption.

Vein of Galen Aneurysmal Malformation: Treatment by Transarterial Venous Sac and Fistula Embolization Using Coils and Glue / 신경중재치료의학

The endovascular treatment goal of vein of Galen aneurysmal malformation (VGAM) is to occlude the shunt. We present a case of successfully treated mural type VGAM by transarterial coil embolization of the ectatic venous pouch, followed by additional transarterial coil and glue embolizations of the ectatic vein and shunt due to recurrence.

Diagnostic Usefulness of CT-guided Pe rcutaneous Biopsy of the Spine

PURPOSE: To evaluate the diagnostic value of CT-guided percutaneous biopsy of inflammatory and tumorous lesions of the spine and paraspinal soft tissue. MATERIALS AND METHODS: Twenty-three patients underwent CT-guided percutaneous biopsy of the spine and paraspinal soft tissue. Tentative clinical diagnoses determined before biopsy were tuberculous spondylitis (n=5), pyogenic spondylitis (n=4), butterfly vertebra (n=1), old compression fracture (n=3), discitis (n=1), hemangioma (n=1), metastasis (n=7) and multiple myeloma (n=1). Biopsy was performed at the following levels: cervical-(n=1), thoracic-(n=9), and lumbar-spine(n=13). The approach to biopsy of the spine and paraspinal soft tissue lesions was posterolateral (n=11), posterior (n=2), or transpedicular (n=10). RESULTS: Tissue considered adequate by the pathologist involved was obtained in 21 (91%) of the 23 cases. In 19 cases, pathologic findings supported the clinical diagnoses determined before biopsy. In two cases, pathologic and clinical diagnoses differed. Complications such as severe pain, bleeding, infection, neurologic deficit or damage to internal organs were detected neither during or after the procedure. CONCLUSION: CT-guided percutaneous biopsy is a safe and reliable method of obtaining a diagnosis in many cases involving different spinal and paraspinal lesions.
