Surgical outcomes after superior vena cava reconstruction with expanded polytetrafluoroethylene grafts.

چکیده
OBJECTIVES Graft occlusion is a problem after superior vena cava (SVC) reconstruction for thoracic malignancy. Expanded polytetrafluoroethylene (ePTFE) is considered to be an optimal material for venous reconstruction. METHODS We reviewed the hospital records of 13 patients who underwent complete resection of thoracic malignancy invading the SVC, including SVC reconstruction with ePTFE grafts. Single bypass grafting was performed in two patients (one right-sided, one left-sided) and double bypasses grafting was performed in the other patients. All patients received antithrombotic therapy after surgery. Eight patients died of recurrence or other disease during the follow-up period (range 5-41 months). RESULTS Of the 24 grafts in 13 patients, graft patency was confirmed in 20 grafts in 9 patients at a mean time follow-up time of 47.8 ± 50.0 months after surgery. In the remaining four grafts in four patients, occlusion was diagnosed at a mean time of 1.25 ± 0.50 months after surgery. All obstructed grafts were left-sided bypass grafts in patients who underwent double bypass grafting, and did not result in SVC syndrome. CONCLUSIONS SVC reconstruction with ringed ePTFE grafts was safe and had good outcomes. In patients who underwent double bypasses grafting, the left-sided bypass grafts were susceptible to occlusion.

Usefulness of artificial vascular graft for venous reconstruction in liver surgery
BACKGROUND The purpose of this study was to evaluate the results of hepatectomy with inferior vena cava or hepatic vein resection, followed by vessel reconstruction with an artificial vascular graft. METHODS From 2000 to 2011, 1,434 patients underwent several types of hepatectomy at our institution. Of these, we reviewed the cases of eight patients (0.56%) who underwent hepatectomy with infer...
متن کاملSuperior vena cava (SVC) reconstruction using autologous tissue in two cases of differentiated thyroid carcinoma presenting with SVC syndrome
Herein, we report two extremely rare cases of differentiated thyroid carcinoma (DTC) with extended tumor thrombus or mediastinum lymph node metastasis (LNM) involving the superior vena cava (SVC), causing SVC syndrome. Both of these patients were successfully treated with radical resection and reconstruction of the SVC using autologous tissue instead of an expanded polytetrafluoroethylene (ePTF...
متن کاملReconstruction using a pericardial tube and ringed Gore-Tex graft for malignant superior vena cava syndrome: report of two cases.
Superior vena cava (SVC) syndrome caused by malignant tumors in the upper mediastinum is not uncommon. Radiation therapy or endovascular treatment with stenting is the first choice of treatment to relieve symptoms. However, surgical treatment may be considered when the less invasive treatment modalities failed. In this report, we present two cases of severe symptomatic SVC syndrome as a result ...
متن کاملSynthetic graft for reconstruction of middle hepatic vein tributaries in living-donor liver transplant.
OBJECTIVES In middle hepatic vein dominant livers, the anterior segment of the right lobe of the liver (segments V and VIII) drains mainly into the middle hepatic vein. In these donors, when right lobe grafts are procured without the middle hepatic vein, the graft may harbor large segment V and/or VIII veins that need reconstruction to avoid graft congestion and subsequent graft dysfunction. Dr...
متن کاملComment: Leiomyosarcoma of the retrohepatic vena cava: Report of a case treated with resection and reconstruction with polytetrafluoroethylene vascular graft.
Leiomyosarcoma of the vena cava is a rare malignant tumor. A 61-year-old woman was admitted with right upper quadrant abdominal pain. Computed tomography revealed a retrohepatic vena cava tumor originating 2 cm below the confluence of the hepaic veins and ending 2 cm above the renal veins. The tumor was resected with 1 cm clear surgical margins, without requiring liver resection. Polytetrafluor...
