Diagnostic Modalities for IVC Thrombosis (A to C) Catheter venography (A) and CT venography (B) in a patient with massive compressive leiomyoma (inset). Note the decompression of the IVC after hysterectomy showing re-expansion of the IVC filter along with resolution of the thrombus (C). Dashed arrow indicates the IVC filter. Asterisk indicates a leiomyoma. (D) A renal (99m-technetium diethylene triamine pentaacetic acid [DPTA]) scan suggestive of renal vascular compromise due to severely reduced uptake of DPTA bilaterally. A′ shows a sudden drop in perfusion at the level of the kidneys (circled) compared with normal perfusion in the spleen (arrow). B′ illustrates a 60-s time activity curve with markedly delayed tracer uptake in the right and left renal arteries indicative of renal vascular compromise. C′ shows delayed (0 to 30 min) static images at 2-min intervals with persistent tracer uptake is seen in both kidneys at 30 min, suggestive of renal vascular obstruction. (E) Catheter venography in a patient with chronic IVC thrombosis and a prior IVC filter. Dashed arrow indicates the IVC filter. Double asterisks indicate significant collateral formation below the site of IVC occlusion. (F) CT venography in a patient with IVC thrombosis extending to the IVC/RA junction. White arrow indicates the IVC thrombus; dashed arrow indicates the IVC filter. LT = left; RT = right; other abbreviations as in Figure 2.
