The value of 99mTc macroaggregated albumin lung perfusion scanning in the prediction of postpneumonectomy function and pulmonary artery pressure.
99mTc macroaggregated albumin lung perfusion scans were performed with assessment of pulmonary hemodynamics in 14 male patients with a centrally located lung tumor, subjected to pneumonectomy. In 7 patients perfusion of the affected lung was less than one third of total perfusion. However, all tumors were resectable. ⋯ A fair but not significant correlation existed in the prediction of vital capacity (VC, r = 0.64) and total lung capacity (TLC, r = 0.71). No correlation was found between perioperative change in mean pulmonary artery pressure (MPAP) and either relative radionuclide uptake of the affected lung or predicted FEV1. So, the lung perfusion scan cannot be used in preoperative estimation of postoperative MPAP.

Effect of fibrin sealant on the tensile strength of rat visceral pleura.
Post mortem studies of rat lungs showed that application of fibrin sealant augments the tensile strength of the lung/visceral pleura by approximately 100 mmHg, thus impeding air leakage.
