“…The pigtail catheter is a fragmentation catheter that consists of a radiopaque tip that is advanced over a guide wire. The catheter shaft is rotated manually and the embolus is fragmented by mechanical action of the recoiled pigtail [reproduced with permission from 13]. c Oasis catheter (Boston Scientific/Meditech).…”

“…This concept was chosen under the consideration that the pigtail tip avoids perforation and allows easy manipulation into and within the pulmonary arteries [11, 12]. In 1998, Schmitz-Rode et al [13]presented data of 10 patients that underwent fragmentation thrombectomy with a rotational pigtail catheter. Seven of the 10 were successful.…”

“…Possible disadvantages of these fragmentation devices is the formation of embolic ‘cast’ as particles from the embolus dislodge and occlude smaller peripheral pulmonary arteries [14]. In addition, mechanically induced neurohormonal release can cause significant pulmonary vasoconstriction with subsequent pulmonary hypertension [10, 13]. …”
Acute massive pulmonary embolism (PE) is a frequently fatal event that causes significant compromise of hemodynamic stability. Unfortunately, mortality rates for PE have remained relatively constant despite advances in prophylactic and treatment measures. In addition to embolus size, symptom recognition for diagnosis and emergent treatment are two distinct factors that dictate survival. Treatment generally includes thrombolytic agents; however, not all patients are candidates for aggressive thrombolytic management. Development of catheter thrombectomy devices provides an alternative treatment modality for severe cases when thrombolytics are contraindicated. Catheter thrombectomy devices have undergone major advances over the last decade, but literature support of their success is limited.

“…Es stehen verschiedene Systeme zur perkutanen Embolektomie sowie zur Katheterfragmentation und -thrombektomie zur Verfügung [3,8,13,19,21,23,26,30,31,32,33,34,35].…”
Pulmonary embolism in the early postoperative period is characterized by high morbidity and mortality. Systemic application of thrombolytic agents during this time is contraindicated; operative thrombectomy also has a high mortality rate. We report a case of successful local lysis in combination with catheter fragmentation of a massive two-sided pulmonary embolism diagnosed on the 4th postoperative day after pylorus-preserving duodenopancreatectomy for distal carcinoma of the common bile duct. Thrombolysis was performed in three sessions by a combination of catheter-supported interventional fragmentation of the thrombus with local rt-PA lysis. There were no bleeding complications or disturbances of anastomotic healing. The patient was discharged from the hospital on the 23rd postoperative day after changing anticoagulation to a vitamin K antagonist. The case presented demonstrates the possibility of local lysis in combination with interventional methods as a therapeutic option for pulmonary embolism in the early postoperative period as an alternative to surgical strategies.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
