Splenic contraction: a new member of the hypovolemic shock complex.

Objective: The objective of the article is to assess changes in splenic volume in the setting of hypovolemic shock; splenic enhancement in hypovolemic shock is also assessed.

Materials/methods: 71 consecutive adult patients with the hypovolemic shock complex on computed tomography (CT) were identified. Spleen volume and enhancement were compared to a baseline CT scan (without shock) or to height- and sex-corrected normal values and a control population when a comparison CT was unavailable.

Safety of an intercostal approach for imaging-guided percutaneous drainage of subdiaphragmatic abscesses.

Objective: The objective of our study was to test the hypothesis that an intercostal approach to imaging-guided percutaneous subdiaphragmatic abscess drainage is as safe as a subcostal approach.

Materials And Methods: A cohort of 258 consecutive patients with one or more subdiaphragmatic abscesses referred for imaging-guided (CT or ultrasound) percutaneous drainage was identified. Demographic characteristics and clinical outcomes were compared between patients who underwent drainage catheter placement via an intercostal approach versus those who underwent drainage catheter placement via a subcostal approach.

Coil embolization of the splenic artery: impact on splenic volume.

Purpose: To determine the impact of coil embolization of the splenic artery on splenic volume based on computed tomography (CT) imaging.

Materials And Methods: Splenic artery embolization (SAE) was performed in 148 consecutive patients over an 8-year period in an institutional review board-approved retrospective study. Of these, 60 patients (36 men; mean age, 49 y) had undergone contrast-enhanced CT before and after SAE with a mean time interval of 355 days.

Safety of catheter-directed thrombolysis for deep venous thrombosis in cancer patients.

Background: The current study was conducted to demonstrate that catheter-directed thrombolysis for upper and lower extremity deep vein thrombosis is equally safe in patients with and without cancer.

Methods: A retrospective cohort of consecutive patients with acute iliofemoral or brachiosubclavian deep vein thrombosis treated with catheter-directed thrombolysis was identified. Demographic characteristics and clinical outcomes were compared between patients with cancer and without cancer.
