WilliamsAbstractBetween September 2008 and August 2017, 36 patients (mean age 56 y; range, 30–89 y) underwent transvenous biopsy of suspected tumor thrombus or perivascular tumor. Intravascular biopsy was pursued because of inaccessible percutaneous access in 9 patients (25%) and as part of a planned revascularization procedure in 27 patients (75%). Histopathologic results showed malignancy in 26 patients (72%) and benign etiologies in 10 patients (28%). No patients required repeat biopsy. There were no complications related to the biopsy procedure. The present series suggests that transvenous biopsy is a safe and accurate method of intravascular and perivascular mass tissue sampling.
