David W. Newell, MD, Swedish Neuroscience Institute, Seattle, WA, presented findings from the Safety of Lysis with EKOS Ultrasound in the Treatment of Intracerebral and Intraventricular Hemorrhage (SLEUTH).\u003C\/p\u003E\u003Cp id=\u0022p-3\u0022\u003EThere are many catheter-based treatments for ICH, but clot resolution rates are greatly dependent on proper catheter placement [Morgan T et al. \u003Cem\u003EActa Neurochir Suppl\u003C\/em\u003E 2008]. Additionally, ultrasound may promote the effect of tPA and aid in the dissolution of clots. The purpose of the SLEUTH study was to evaluate the safety of adding catheter-delivered ultrasound to catheter-based lysis in ICH and IVH (\u003Ca id=\u0022xref-fig-1-1\u0022 class=\u0022xref-fig\u0022 href=\u0022#F1\u0022\u003EFigures 1A\u003C\/a\u003E and \u003Ca id=\u0022xref-fig-2-1\u0022 class=\u0022xref-fig\u0022 href=\u0022#F2\u0022\u003E1B\u003C\/a\u003E). This study included 9 patients (mean age=63) who had spontaneous supratentorial ICH \u226525 cc (n=6) and\/or IVH (n=3) that obstructed the third and\/or fourth ventricles (no documented vascular lesion) with symptom onset \u0026lt;12 hours prior to diagnostic CT scan. Treatment occurred within 72 hours. One ICH patient was subsequently excluded from the study analysis due to catheter breakage that occurred during transport to CT. A neuronavigation system was used to locate the catheter and deliver the lytic, and continuous ultrasound was delivered via catheter for 24 hours. The endpoints were 30-day mortality, symptomatic bleeding rate, brain infection, and blood clot resolution. There was a stopping rule in place for increase in hemorrhage size.\u003C\/p\u003E\u003Cdiv id=\u0022F1\u0022 class=\u0022fig pos-float  odd\u0022\u003E\u003Cdiv class=\u0022highwire-figure\u0022\u003E\u003Cdiv class=\u0022fig-inline-img-wrapper\u0022\u003E\u003Cdiv class=\u0022fig-inline-img\u0022\u003E\u003Ca href=\u0022http:\/\/d282kpwvnogo5m.cloudfront.net\/content\/spmdc\/10\/1\/18\/F1.large.jpg?width=800\u0026amp;height=600\u0026amp;carousel=1\u0022 title=\u0022EKOS Micro-Infusion Catheter.\u0022 class=\u0022fragment-images colorbox-load\u0022 rel=\u0022gallery-fragment-images-897597061\u0022 data-figure-caption=\u0022EKOS Micro-Infusion Catheter.\u0022 data-icon-position=\u0022\u0022 data-hide-link-title=\u00220\u0022\u003E\u003Cimg class=\u0022fragment-image\u0022 alt=\u0022Figure 1A.\u0022 src=\u0022http:\/\/d282kpwvnogo5m.cloudfront.net\/content\/spmdc\/10\/1\/18\/F1.medium.gif\u0022\/\u003E\u003C\/a\u003E\u003C\/div\u003E\u003C\/div\u003E\u003Cul class=\u0022highwire-figure-links inline\u0022\u003E\u003Cli class=\u00220 first\u0022\u003E\u003Ca href=\u0022http:\/\/d282kpwvnogo5m.cloudfront.net\/content\/spmdc\/10\/1\/18\/F1.large.jpg?download=true\u0022 class=\u0022highwire-figure-link highwire-figure-link-download\u0022 title=\u0022Download Figure 1A.\u0022 data-icon-position=\u0022\u0022 data-hide-link-title=\u00220\u0022\u003EDownload figure\u003C\/a\u003E\u003C\/li\u003E\u003Cli class=\u00221\u0022\u003E\u003Ca href=\u0022http:\/\/d282kpwvnogo5m.cloudfront.net\/content\/spmdc\/10\/1\/18\/F1.large.jpg\u0022 class=\u0022highwire-figure-link highwire-figure-link-newtab\u0022 target=\u0022_blank\u0022 data-icon-position=\u0022\u0022 data-hide-link-title=\u00220\u0022\u003EOpen in new tab\u003C\/a\u003E\u003C\/li\u003E\u003Cli class=\u00222 last\u0022\u003E\u003Ca href=\u0022\/highwire\/powerpoint\/11213\u0022 class=\u0022highwire-figure-link highwire-figure-link-ppt\u0022 data-icon-position=\u0022\u0022 data-hide-link-title=\u00220\u0022\u003EDownload powerpoint\u003C\/a\u003E\u003C\/li\u003E\u003C\/ul\u003E\u003C\/div\u003E\u003Cdiv class=\u0022fig-caption attrib\u0022\u003E\u003Cspan class=\u0022fig-label\u0022\u003EFigure 1A.\u003C\/span\u003E \u003Cp id=\u0022p-4\u0022 class=\u0022first-child\u0022\u003EEKOS Micro-Infusion Catheter.\u003C\/p\u003E\u003Cq class=\u0022attrib\u0022 id=\u0022attrib-1\u0022\u003EReproduced with permission from D.

No other deaths, infections, or rebleeds were observed.

A 45.1% \u00b1 13 (SEM) mean percentage volume reduction was observed in the IVH group compared with pretreatment stability scans. Patients who were treated with sonolysis + tPA had faster rates of lysis during the first 24 hours of treatment for IVH (p=0.046) and ICH (p=0.074) compared with similar treatment with tPA alone [Morgan T et al. \u003Cem\u003EActa Neurochir Suppl\u003C\/em\u003E 2008; courtesy of D.
