long term experience with transvenous Catheter pulmonary embolectomy
Journal of Vascular Surgery, 1993Co-Authors: Lazar J. Greenfield, Mary C. Proctor, David M. Williams, Thomas W. WakefieldAbstract:Abstract Purpose: Massive pulmonary embolism (PE), defined by systemic hypotension and need for inotropic support, has a high mortality rate. Transvenous Catheter pulmonary embolectomy performed with the patient receiving local anesthetic provides an expeditious alternative to lytic therapy or open embolectomy on cardiopulmonary bypass. Methods: The indication for embolectomy in this series of 46 patients was hypotension despite inotropic support in all but four patients (91%); the latter sustained major embolism and were respirator dependent. In the first 10 patients treated from 1970 to 1974, a metal cup attached to a Straight Catheter was used. Results: Hemodynamic improvement occurred in nine of 10 initial patients, but recurrent PE and a mortality rate of 50% prompted addition of a vena caval filter and directional control to the Catheter. Subsequently 36 patients were treated with this combination from 1975 to 1992. Emboli were extracted in 76% (35 of 46) of the total series with a 30-day survival rate of 70% (32 of 46). Hemodynamic data showed an average reduction in mean pulmonary artery pressure of 8 mm Hg and a significant increase in mean cardiac output from 2.59 L/min to 4.47 L/min ( p = 0.003) after embolectomy. Complications included wound hematoma (15%), pulmonary infarct (11%), recurrent deep venous thrombosis (6%), pleural effusion (4%), and myocardial infarction (4%). Conclusions: Successful embolectomy was most likely for categories of major PE (4 of 4, 100%) and massive PE (27 of 33, 82%) and least likely for chronic PE (5 of 9, 56%) ( p p

Successful embolectomy also predicted long-term survival (p < 0.01), which was 89 months for the series (range 1 to 237 months). Catheter pulmonary embolectomy by surgeon and radiologist is of maximal benefit for major or massive PE but less likely to benefit patients with chronic recurrent PE.

Successful rescue of stuck rotablator burr entrapment using a Kiwami Straight Catheter.
Catheterization and cardiovascular interventions : official journal of the Society for Cardiac Angiography & Interventions, 2015Co-Authors: Takenori Kanazawa, Kazushige Kadota, Kazuaki MitsudoAbstract:Rotational atherectomy is an indispensable modality for percutaneous coronary intervention of severely calcified lesions. An entrapped rotablator burr is a rare but life-threatening complication because retrieval is difficult. Although emergent surgical removal is a reliable option for this complication, it is invasive. There are various methods to retrieve an entrapped burr by bailout endovascular approaches. We present two cases of successful rescue of stuck rotablator burr entrapment using a Kiwami Straight Catheter (4 Fr, Heartrail II, Terumo, Tokyo, Japan).
