Background: To assess the long-term patency of the biologic prosthetic conduit used for reconstruction of the superior vena cava (SVC) by magnetic resonance imaging (MRI). Methods: Patients undergoing oncologic resection and reconstruction of the SVC by a bovine pericardial prosthesis (January 2003 to April 2010) have been studied after 1 year (if surviving) by MRI for the assessment of the conduit long-term patency. Results were compared with those of a control group of patients with normal SVC. Blood flow and area of lumen section at 3 different levels (proximal, middle, distal) were analyzed. Results: Sixteen consecutive patients surviving after 1 year from surgery out of 17 (9 lung cancer, 8 mediastinal malignancy) undergoing SVC reconstruction were included. One patient died postoperatively and was not included. Sixteen patients with similar demographic characteristics were studied in the control group. Mean blood flow was 18.4 ± 3.5 mL/sec (range 14.3 to 25.7) in patients with reconstructed SVC and 20.8 ± 4.1 mL/sec (range 15.3 to 27.7) in the control group. Mean area of the conduit lumen section was 2.2 ± 0.6 cm2 (range 1.6 to 3.6) at proximal level, 2.9 ± 1.3 cm2 at middle level (range 1.3 to 5.7), and 2.1 ± 0.9 cm2 (range 0.5 to 4) at distal level in the reconstructed group, and 2.6 ± 0.7 cm2 (range 1.8 to 4.2), 2.7 ± 0.7 cm 2 (range 1.9 to 4.3), and 2.4 ± 0.3 cm2 (range 1.8 to 3.1), respectively, at proximal, middle, and distal levels in the control group. Differences between the 2 groups were not significant (p > 0.05). Conclusions: The MRI assessment in terms of blood flow and area of lumen section at 3 different levels confirms that bovine pericardial conduit used for SVC replacement shows an optimal patency over the long term. © 2013 by The Society of Thoracic Surgeons.

Abstract

Background: To assess the long-term patency of the biologic prosthetic conduit used for reconstruction of the superior vena cava (SVC) by magnetic resonance imaging (MRI). Methods: Patients undergoing oncologic resection and reconstruction of the SVC by a bovine pericardial prosthesis (January 2003 to April 2010) have been studied after 1 year (if surviving) by MRI for the assessment of the conduit long-term patency. Results were compared with those of a control group of patients with normal SVC. Blood flow and area of lumen section at 3 different levels (proximal, middle, distal) were analyzed. Results: Sixteen consecutive patients surviving after 1 year from surgery out of 17 (9 lung cancer, 8 mediastinal malignancy) undergoing SVC reconstruction were included. One patient died postoperatively and was not included. Sixteen patients with similar demographic characteristics were studied in the control group. Mean blood flow was 18.4 ± 3.5 mL/sec (range 14.3 to 25.7) in patients with reconstructed SVC and 20.8 ± 4.1 mL/sec (range 15.3 to 27.7) in the control group. Mean area of the conduit lumen section was 2.2 ± 0.6 cm2 (range 1.6 to 3.6) at proximal level, 2.9 ± 1.3 cm2 at middle level (range 1.3 to 5.7), and 2.1 ± 0.9 cm2 (range 0.5 to 4) at distal level in the reconstructed group, and 2.6 ± 0.7 cm2 (range 1.8 to 4.2), 2.7 ± 0.7 cm 2 (range 1.9 to 4.3), and 2.4 ± 0.3 cm2 (range 1.8 to 3.1), respectively, at proximal, middle, and distal levels in the control group.
