UAE in women with symptomatic leiomyomas leads to long-term symptom improvement.Predictors of failure were a lack of improvement in bleeding or pain at 1 year and thepercent reduction in dominant tumor volume.

IEAI is most often an iatrogenic injury in a coagulopathic patient. Contrastmedium– enhanced CT can be diagnostic for active bleeding, but in the setting of ongoinghemorrhage a negative study result should not preclude arteriography. Embolization is aneffective means to control hemorrhage.

Although iodized oil accumulation in hypervascular HCCs correlates with the degree oflesion enhancement on CT/HA in most cases, a discrepancy may occur in a substantialnumber of cases, which likely affects the prediction of therapeutic effects in hypervascularHCCs.

Ionic Versus Nonionic Contrast Media Solvents Used with an Epirubicin-based Agent forTransarterial Chemoembolization of Hepatocellular Carcinoma. . . . . . . . . . . . . . . . . . . . 342

Epirubicin–iodized oil emulsions prepared with nonionic contrast medium are more stableand are associated with lower tumor grade in patients with inoperable HCC. The choice ofsolvent, however, does not appear to have an effect on patient survival.

With technical modifications such as transcaval liver biopsy and with access to US in theangiography suite, interventionalist can achieve higher technical success rates for thisprocedure. The authors’ institutional experience with this procedure reiterates its highhistopathologic positivity and safety profile both in adult and pediatric patients.

A more accurate understanding of the superior vena cava anatomy is essential for thecorrect interpretation of central venous access device position. The true cavoatrial junctionis located more inferiorly than commonly believed and is not accurately estimated withcommonly used imaging landmarks. A point two vertebral body units below the carinaenables the reliable estimate of the position of the cavoatrial junction. Catheter tip positioncan be most reliably described in vertebral body units below the carina, with use of thethoracic spine as an internal ruler.
Compression of the Left Common Iliac Vein in Asymptomatic Subjects and Patients withLeft Iliofemoral Deep Vein Thrombosis. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 366

There was considerable overlap between the degree of compression in patients with IVCS andcontrol subjects. Compression of the left common iliac vein was significantly more prominent inpatients with lower extremity deep vein thrombosis due to IVCS when compared with controlsubjects. Compression in excess of 70% as demonstrated at CT can be helpful for identifyingpossible underlying IVCS in patients with a left lower extremity deep vein thrombosis.

Thrombolysis in DVT with the TIC is associated with a greater technical success rate, alower rate of bleeding, and a lower cost than that reported for CDT. These preliminaryresults indicate that further evaluation of the TIC in the treatment of DVT is warranted.
Retrievable versus Permanent Caval Filter Procedures: When Are They Cost-effective forInterventional Radiology? . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 384

The preferential use of retrievable versus permanent devices for filter placement isfinancially advantageous for an IR unit only if at least 41% of them are eventually removed.The use of clinical criteria to select device type allows significant cost savings.

In this retrospective cohort study, RFs and PFs provided similar protection from PE withcomparable complication rates. Clinicians should select an IVC filter based on theprojected duration of filtration needed at the time of placement rather than filter type.

Suvranu Ganguli, Darren D. Brennan, Salomao Faintuch, Mostafa E. Rayan, andS. Nahum Goldberg
Renal tumors decrease in size immediately after treatment with RF thermal ablation.Immediate tumor involution after RF ablation should be anticipated and follow-up imagingstudies should ideally be compared to a baseline tumor size measured as soon as possibleafter ablation.
