AbstractTotal anomalous pulmonary venous connection (TAPVC) is a rare congenital cardiac malformation, and prenatal detection of TAPVC malformation remains a challenging. TAPVC can be easily missed or misdiagnosed in prenatal examinations. This study was aimed to use the modified vascular corrosion casting technique to prepare fetal cardiovascular casts with TAPVC and investigate the utility of cardiovascular casting for the demonstration of fetal TAPVC. The retrospective study enrolled twenty fetuses (22 to 29 + 4 gestational weeks) with TAPVC diagnosed by prenatal echocardiography and casting technique from May 2015 to May 2020. Pre- and postnatal medical records, including results obtained by prenatal ultrasound, postpartum computed tomography angiography, as well as anatomic and cardiovascular casting findings were carefully reviewed and analyzed. In twenty cases, 80% (16/20) had intra- or extracardiac malformations. The TAPVC types were supracardiac (n = 8), cardiac (n = 6), infracardiac (n = 4), and mixed (n = 2). The diagnosis of 1 case each of supracardiac and cardiac TAPVC was modified to partial anomalous pulmonary venous connection; additionally, 4 malformations were missed and 2 were misdiagnosed, including an anomalous left brachiocephalic vein in supracardiac TAPVC, abnormal inflow of the hepatic vein and a double inferior vena cava in infracardiac TAPVC; and bilateral ductus arteriosus in infracardiac TAPVC; a tetralogy of Fallot in cardiac TAPVC that was corrected to right ventricular double outlet; and an absence of ductus arteriosus that was misdiagnosed as slim ductus arteriosus. Comparing with ultrasound, casting technique has its own superiority in exhibiting TAPVC abnormalities, especially in certain types such as course, origin and absence abnormalities of ductus. Postpartum cardiovascular casts can accurately depict the branch structure of the heart’s larger vessels, and may be used as a clinical assessment and teaching method in complex cardiac malformations.

Quantitative Measurements

Preparation of replicas of the complex arrangement of blood vessels in various organs and tissues has been accomplished by infusing low viscosity resins into the vasculature. Subsequent removal of the surrounding tissue by maceration leaves a model of the intricate three-dimensional anatomy of the blood vessels of the tissue not obtainable by any other procedure. When applied with care, the vascular corrosion casting technique can reveal fine details of the microvasculature including endothelial nuclear orientation and distribution (Fig. 1), locations of arteriolar sphincters (Fig. 2), venous valve anatomy (Fig. 3), and vessel size, density, and branching patterns. Because casts faithfully replicate tissue vasculature, they can be used for quantitative measurements of that vasculature. The purpose of this report is to summarize and highlight some quantitative applications of vascular corrosion casting. In each example, casts were prepared by infusing Mercox, a methyl-methacrylate resin, and macerating the tissue with 20% KOH. Casts were either mounted for conventional scanning electron microscopy, or sliced for viewing with a confocal laser microscope.

In this study, 10 Hasak sheep lungs from Konya Bahri Dağdaş International Agricultural Research Institute, Unit of Experimental Animals Unit were used. Corrosion casting technique were applied to the materials. The corrosion cured materials were stored in water for one night. It was then incubated at 37 ° C in a 20% KOH solution for 24 hours. Corrosion casting technique and latex injection materials were photographed and presented in the study. The lungs were found to be wrapped with pleura visceralis (pleura pulmonalis) in the cavum thoracis. It was determined that the right lung was consisted of lobe cranialis (pars cranialis and pars caudalis), lobus medius, lobus caudalis and lobus accessorius. The left lung was composed of lobe cranialis (pars cranialis and pars caudalis) and lobe caudal. In the bronchus that shaped these lobes, it was determined that tacheae gave bronchus lobaris cranialis dexter (bronchus trachealis) mean 48.53 mm before the bifurcatio trachea, and later on it was divided into bronchus pirincipalis dexter and sinister. In this study, anatomical features of broncho-pulmonary segmentation and similarities and differences with other species were revealed.
