Table 1 Study characteristics and findings
Study, year | Country | Study type | Population | Number of patients | Age, year | Interventions | Follow-up, month | Measurement | Outcome, score | Mortality, % | Conclusion |
|---|---|---|---|---|---|---|---|---|---|---|---|
Wang et al., 2006 [13] | China | Prospective | Single-center | 18 | 63.5 | Physical removal of hematoma through craniotomy, septostomy approach, and EVD | 6 | GOS | 3.83 | 5.6 | Physical removal of the clot through an open exposure of the lateral ventricle approaching it from above through the corpus callosum made a rather impressive success rate |
Yadav et al., 2007 [14] | UK | Prospective | Multi-center | 25 | - | Endoscopic removal of hematoma and ETV for hydrocephalus | 6 | GOS | 3.32 | 24 | Encouraging results had been shown thorough endoscopic management on hypertensive IVH patients with obstructive hydrocephalus |
Hamada et al., 2008 [15] | Japan | Retrospective | Single-center | 15 | 62 | Endoscopic removal of hematoma and EVD | - | mRS | 3.47 | 0 | Endoscopy is of importance in the management of non-communicative hydrocephalus |
Staykov et al., 2009 [16] | Germany | Prospective | Single-center | 32 | 61 | Treatment algorithm of IVF, EVD, and early application of LD | 6 | mRS | 62.5% with good outcome (0–3) | 15.6 | First prospective study investigating combined treatment of IVF, EVD, and LD |
Chen et al., 2011 [17] | China | Randomized controlled trial | Single-center | 48 | 63.9 | Endoscopic removal of hematoma and following EVD /traditional EVD | 3 | GOS | 3.08 vs 3.33 | 20.8 vs 16.6 | Endoscopic surgery had a significant lower incidence of shunt-dependent hydrocephalus and a shorter ICU stay compared with EVD surgery, and this can decrease the need for permanent VP shunt in IVH caused by thalamic hemorrhage |
Wang et al., 2013 [13] | China | Randomized controlled trail | Multi-center | 45 | 55.4 | EVD and IVF | 1 | GOS | 3.36 | 15.6 | EVD plus EVT from the ipsilateral ventricle had faster blood clearance in the third and fourth ventricles than in the contralateral ventricle. Clinical outcome were similar in two strategies. Also, this is the first study investigating the effect of catheter location of EVD on patients’ outcome |
Xia et al., 2014 [18] | China | Prospective | Single-center | 8 | 68 | EVD and early CLD | 6 | GOS | 3.62 | 13 | First prospective study providing insight into the safety, feasibility, and potential benefit of combining early CLD with EVD in moderate to severe IVH regardless of the presence of obstructive hydrocephalus |
Obaid et al., 2015 [19] | Cananda | Retrospective | Single-center | 8 | 58 | Endoscopic removal of hematoma and ETV for hydrocephalus | 21.3 | mRS | 3.5 | 37.5 | ETV with or without endoscopic clot evacuation is a safe and effective method to treat IVH-related obstructive hydrocephalus |
Ogiwara et al., 2021 [20] | Japan | Retrospective | Multi-center | 8 | 54.4 | Endoscopic removal of hematoma and ETV for hydrocephalus | At discharge | mRS | 3 | 0 | Tailor-made endoscopic strategy revealed a good hematoma evacuation rate and potential for improved functional outcome |
