Massive pulmonary embolism: percutaneous emergency treatment by pigtail rotation catheter

Current Status of Percutaneous Mechanical Thrombectomy. Part II. Devices and Mechanisms of Action

Use of Rheolytic Thrombectomy in Treatment of Acute Massive Pulmonary Embolism

Three catheter interventional techniques are currently available for removing or fragmenting pulmonary emboli: aspiration thrombectomy, fragmentation, and rheolytic thrombectomy. The investigators systematically reviewed all available published research related to the use of catheter-tip devices in patients with pulmonary emboli. Pooled data showed that clinical success with the Greenfield catheter occurred in 72 of 89 patients (81%) when used alone and in 19 of 19 patients (100%) when used in combination with thrombolytic agents. Fragmentation with standard catheters used alone (without thrombolytic agents) was reported in only 3 patients. Clinical success with standard angiographic catheters occurred in 15 of 21 patients (71%) when used in combination with systemic thrombolytic agents and in 115 of 121 patients (95%) when used with local infusions of thrombolytic agents. Data for the Amplatz catheter, the rheolytic Angiojet catheter, and the Hydrolyser catheter when used alone were sparse or absent. Clinical success when used in combination with thrombolytic agents occurred in 6 of 6 patients (100%) with the Amplatz catheter, in 20 of 23 patients (87%) with the Angiojet catheter, and in 19 of 20 patients (95%) with the Hydrolyser catheter. Minor bleeding at the insertion site among all patients, with and without thrombolytic agents, occurred in 29 of 348 patients (8%), and major bleeding at the insertion site occurred in 8 of 348 patients (2%). One patient experienced perforation of the right ventricle with the Greenfield catheter. None reported perforation of a pulmonary artery. In conclusion, all the devices analyzed in this study appear to be useful in the management of acute massive pulmonary emboli.

Catheter-tip embolectomy in the management of acute massive pulmonary embolism

Massive Pulmonary Embolism: Preliminary Results of Treatment with the Amplatz Thrombectomy Device☆

PURPOSE: A modified pigtail catheter for angiographic documentation and mechanical fragmentation of pulmonary embolism was evaluated for its efficacy and safety. MATERIALS AND METHODS: Rotation of the 5-F pigtail catheter was performed with an electric drive or a handle. The wire left an oval side hole at the outer curvature and served as an axis of rotation. Fragmentation properties were assessed in vitro. Pulmonary positioning, steerability, rotation behavior, and safety were tested in six pigs. Pulmonary embolic occlusions were recanalized in eight dogs. RESULTS: The catheter system was promptly positioned and easily steered in the pulmonary arteries. On average, 53% of the occluded pulmonary arteries were recanalized. Recanalization reduced the emboli-induced elevation of the pulmonary artery mean pressure by 73%. Slight perivascular hemorrhage occurred in three dogs. CONCLUSION: Rapid partial recanalization was achieved with relative ease of instrumentation. The technique is an extension of the commo...

Diagnostik und Fragmentationstherapie der akuten massiven Lungenembolie mit einem rotierbaren Pigtail-Katheter : Experimentelle Studien

PURPOSE A dedicated pigtail catheter system which allows angiographic documentation and adjunctive mechanical fragmentation of pulmonary emboli was evaluated in an animal experiment. MATERIAL AND METHOD The 5-F catheter provided with an oval side hole proximal to the pigtail tip was rotated manually or with an electric drive, and with the wire as a rotation axis. Pulmonary embolic occlusions were recanalized in ten dogs. Catheter positioning, monitoring, rotation behaviour, safety and fragmentation properties were assessed. RESULTS The catheter system was rapidly positioned and easily monitored in the pulmonary arteries. On average, 55% (+/- 20%) of the embolic occlusions were recanalized. Embolus fragmentation reduced the emboli-induced increase of the pulmonary arterial mean pressure by 72%. In three dogs, histology revealed slight perivascular haemorrhage. CONCLUSION Partial recanalisation of the pulmonary arteries was achieved rapidly with relative ease of instrumentation. Since fragmentation technique is an adjunct to the commonly performed pigtail catheterization of the pulmonary arteries, no special training is required.
