Figure 2 Angiographical description of thrombectomy and thrombolysis/fragmentation. (A) A 9-Fr guiding sheath was advanced supported with EGoist interventional guide wire. (B) Initial angiography showed occlusion of peripheral brunch of right interlobal pulmonary artery (PA). Red arrow indicates occluded artery. (C) An 8-Fr PTCA guiding catheter was inserted through the 9-Fr guiding sheath to the right interlobal PA, and thrombectomy was performed by applying negative pressure. Yellow arrow indicates the percutaneous transluminal coronary angioplasty (PTCA) guiding catheter. Yellow triangle indicates the 9-Fr guiding sheath. (D) Thrombi are aspirated by 8-Fr PTCA guiding catheter. (E) Thrombolysis and mechanical thrombus fragmentation was performed by injecting recombinant tissue plasminogen activator and rotating pigtail catheter manually. Yellow arrow indicates the pigtail catheter. (F) Angiography after thrombolysis and mechanical fragmentation. Red arrow indicates the peripheral brunch of right interlobal artery. Thin red arrow indicates the residual thrombus.
