Massive pulmonary embolism: percutaneous mechanical thrombectomy during cardiopulmonary resuscitation.
Seven patients with massive pulmonary embolism (PE) causing cardiac arrest underwent percutaneous mechanical thrombectomy (PMT) with Hydrolyser and Oasis catheters during cardiopulmonary resuscitation (CPR). Three received adjunctive recombinant tissue plasminogen activator. Thrombectomy was successful in restoring pulmonary perfusion in six patients (85.7%). ⋯ There was one groin hematoma that required blood transfusion. In conclusion, massive PE causing cardiac arrest can be treated with PMT simultaneously with CPR maneuvers to rapidly revert circulatory collapse, with restoration of pulmonary circulation. Larger series are needed to validate this method.

To determine the tolerance of 0.021-inch and 0.027-inch microcatheters to power injection in an in vitro flow model. ⋯ The majority of microcatheters can be power-injected in vitro at pressures far greater than manufacturer recommendations. When fractures occur, they are near the hub of the catheter. Significantly greater rates of injection are possible through 0.027-inch catheters.

Cutting balloon angioplasty for primary treatment of hemodialysis fistula venous stenoses: preliminary results.
To assess the efficacy of the cutting balloon as the primary tool in percutaneous transluminal angioplasty of hemodialysis access stenoses. ⋯ The high degree of technical and clinical success likely reflects the lack of major complications. The 6-month follow-up results match those of other series. Further follow-up will show whether this technique produces better results over the long term.
