Contrast medium– enhanced CT can be diagnostic for active bleeding, but in the setting of ongoing hemorrhage a negative study result should not preclude arteriography. Embolization is an effective means to control hemorrhage. Iodized Oil Accumulation in Hypervascular Hepatocellular Carcinoma after Transcatheter Arterial Chemoembolization: Comparison of Imaging Findings with CT during Hepatic Arteriography ................................................. 333 Takeshi Fujita, Katsuyoshi Ito, Masahiro Tanabe, Shigenari Yamatogi, Hideko Sasai, and Naofumi Matsunaga Although iodized oil accumulation in hypervascular HCCs correlates with the degree of lesion enhancement on CT/HA in most cases, a discrepancy may occur in a substantial number of cases, which likely affects the prediction of therapeutic effects in hypervascular HCCs.

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.

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.

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.

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.
