Pulmonary arterioplasty and vena cava reconstruction as part of lung cancer resection Bryan F. Meyers MD MPH Patrick and Joy Williamson Professor of Surgery
Definition:T4 • Tumor of any size characterized by one of the following: (1) invasion of the trachea, carina, heart, great vessels, vertebral body, esophagus, or mediastinum, (2) one or more satellite tumor nodules in the same lobe, or (3) malignant pleural effusion Rice & Blackstone, 2002
Synthesis of Studies T4 Resections Bernard et al., Eur J Cardiothor Surg, 2001
SVC Involvement • Majority are unresectable • N2, distant mets, extensive mediastinal inv. • Issues • amount of circumferential involvement • need for clamping (how long is too long?) • increased ICP, brain damage • reduction in cardiac inflow • Operative mortality 5-7% • Median and 5 year survival modest
Case Presentation • 70 y/o with HTN • CXR: right perihilar mass • CT : 4.5 cm central mass • SVC compressed • Tumor abutting aorta and PA • FNA revealed adenocarcinoma
Case Presentation • Induction chemotherapy with response • repeat CT and PET scan • Mediastinoscopy negative • PET: FDG activity in right hilum • All metastatic work-up negative
Case Presentation • Right pneumonectomy • Large mass anterior to right main PA • Involved pericardium, phrenic nerve, lateral border of SVC, superior pulmonary vein • Central involvement required amputation at SPV/atrial junction • SVC encircled, central line in RA, SVC amputated along lateral wall & patched
Variable degrees of resection and reconstruction • Tangential resection and simple closure • Tangential resection and patch • Complete resection with interposition graft reconstruction
Variable approaches • Thomas et al, 1994 • 11 lateral, 4 circumferential resections • 9 sutured, 2 patched, 4 tube grafted • Misthos et al, 2007 • 8 lateral and 1 circumferential • 3 sutured, 5 patched, 1 tube graft
Example of Tangential Resection and Closure • Central right upper lobe tumor • Bronchus, PA and PV all transected with negative margins • Close abutment and possible invasion of SVC near azygous
Considerations of Tangential Resection • Simple • Narrows the SVC- watch for central line or portocath • Judgement about how much to narrow before patching • Avoid staples on specimen- will hinder margin assessment
Dartevelle 2009 • Results of Primary Surgery With T4 Non–Small Cell Lung Cancer During a 25-Year Period in a Single Center: The Benefit is Worth the Risk • BedrettinYıldızeli, MD, Philippe G. Dartevelle, MD, ElieFadel, MD, SachaMussot, MD, and AlainChapelier, MD • Department of Thoracic and Vascular Surgery and Heart-Lung Transplantation, Hôpital Marie-Lannelongue, Paris-Sud University, • Le Plessis Robinson, France • Ann ThoracSurg 2008;86:1065–75
Yildizelli and Dartevelle • 39 cases of SVC invasion • Resections included: • 32 right pneumonectomy • 5 right upper lobectomy • 2 wedge resection • Stages included: • 18 were N1, 16 were N2/3; 1 was M1 • Median surv 19 months, 5YS 29% Ann ThoracSurg 2008;86:1065–75
SVC Resection: Factors Influencing Long-Term Survival • Survival • median survival 11 months • 1, 3, 5 year survival 49%, 25% and 21% • pneumonectomy vs lobe (death risk) • No other factor associated with survival • T status • N status Spaggiari et al., in press JTCVS 2002
Survival T4 Lung Cancers - Tracheal, Carinal, Atrial, Aortic, SVC, Vertebral Body Involvement 19 mo Rice & Blackstone, 2002
Conclusions • Radical resections for T4 NSCLC can be achieved with acceptable morbidity, mortality and survival • Best prognosis in SVC invasion with partial resection/closure/patch • Complete resection, in all series, key to any reasonable survival • Patient selection, induction/adjuvant therapy might impact outcome

Pulmonary arterioplasty • Always upper lobe problem • Usually left upper lobe issue (70:30 in Venuta/Rendina series) • Similar concerns as for SVC invasion: • Complete resection important • Consideration of nodal and distant mets • Variable options to reconstruct based on extent of resection
Case presentation 70 year old with dysphagia Swallow negative for good explanation Left hilar mass noted- CT scan obtained
Issues • Pneumonectomy sparing options should be considered • Bronchial sleeve would be hampered by apparent PA involvement • Potential complete resection with sparing of LLL using double sleeve • More common presentation is more peripheral tumor abutting PA
Technical options • Primary suture closure • Patch with various materials • Autologous pericardium • Autologous pulmonary vein • Bovine pericardium • Sleeve PA plasty without prosthetic • Conduit reconstruction
