Why the study?
Does mechanical thrombus fragmentation with a rotating pigtail catheter affect pulmonary arterial pressure and cause distal embolisation in patients with acute massive pulmonary thromboembolism?
Population
25 patients with acute massive pulmonary thromboembolism and haemodynamic impairment.
Design

Distal embolisation during fragmentation may raise pulmonary pressure; hypothesis-generating for adjunctive strategies in massive PE, should not change practice.
Does mechanical thrombus fragmentation with a rotating pigtail catheter affect pulmonary arterial pressure and cause distal embolisation in patients with acute massive pulmonary thromboembolism?
Mechanical fragmentation of massive pulmonary embolism can cause distal embolisation and transient pulmonary pressure elevation, which can be mitigated by subsequent thrombolysis and aspiration.
NAKAZAWA et al. (2008) studied this question.
