Percutaneous inferior vena caval filters: follow-up of seven designs in 320 patients.

Abstract

Three hundred twenty-four percutaneous inferior vena caval (IVC) filters of different designs were placed in 320 patients from April 1985 through June 1992. No acute mortality or substantial morbidity was attributed to filter placement. Radiologic or pathologic follow-up data were obtained in 227 (71%) patients (230 filters); clinical follow-up data only were obtained in 50 (16%) patients (50 filters). One hundred twenty (43%) patients died; post-filter-placement pulmonary emboli (PE) were related to the cause of death in eight. At IVC filter imaging studies, 26 of 137 (19%) filters demonstrated caval thrombus; 12 of 132 (9%) filters had delayed penetration through the IVC wall of greater than 3 mm; 13 of 230 (6%) filters migrated more than 1 cm; and five of 230 (2%) filters had fracture of a strut or leg. Deep venous thrombosis (DVT) at the insertion puncture site or in the lower extremity was noted in 26 of 117 (22%) cases of filter placement. Among patients without imaging studies, clinical suspicion of complications included PE in four patients, IVC thrombus in 14 patients, and lower-extremity DVT in 10 patients. Long-term clinical and radiologic follow-up of all IVC filters is indicated due to the relatively high prevalence of some complications.

Sudden Cardiac Death Caused by Migration of a TrapEase Inferior Vena Cava Filter: Case Report and Review of the Literature

“…We assumed that the pelvic veins were the source, although we could not safely exclude an embolization from the legs. Complications of IVC filter include recurrent PE (2-5%), 1 -3 of IVC filter thrombosis (2.7-19%) 4,5 and, rarely, IVC filter migration to the heart or lungs. 4,5 Incidence of IVC filter migration has decreased during the last decade, probably as a result of improved strut design preinsertion venography to measure caval diameter.…”

Vena Kava Filtre Yerlestirme

“…İşlem sonrası 1000 mL mayi üç saatte gidecek şekilde verilebilir. Teknik başarı oranı %95-100 arasındadır [15]. Geçici filtreyi yerleştirdikten sonra genel yaklaşım filtreyi emboli riski ortadan kalktığında çıkartmaktır.…”

“…Filtre migrasyonu yaklaşık %6 oranında gelişir ve genelde asemptomatiktir [15]. Ancak bazı vakalarda intrakardiyak migrasyon sonucu kardiyak şok tanım-lanmıştır [24].…”

“…Filtre penetrasyonu diğer bir olası problemdir. Yaklaşık %9 vakada 3 mm'den fazla penetrasyon olabileceği vurgulanmıştır [15]. İVK trombüsü en sık tartışılan problemdir ve literatürde %2-30 oranında olabileceği belirtilmiştir [9].…”
