Rare Association

Persistent left superior vena cava (PLSVC) is the most frequent abnormality in the general population with the frequency of 0.1% to 0.5%. It results from the failure of the involution of the left anterior cardinal vein. Right and Left SVC can coexist together in 80% to 90% of cases. Association of PLSVC with ano rectal malformation (ARM) is very rarely reported. Hence, here is a report of a unique case of PLSVC in a female neonate with ARM

Endothelin (ET) from a nontetrapod species has never been characterized, either structurally or biologically. A single molecular form of trout ET with 21-amino-acid residues was isolated in pure form from an extract of the kidney of the steelhead trout, Oncorhynchus mykissand its primary structure established as Cys-Ser-Cys-Ala-Thr-Phe-Leu-Asp-Lys-Glu10-Cys-Val-Tyr-Phe-Cys-His-Leu-Asp-Ile-Ile20-Trp. This amino acid sequence shows only three substitutions (Ala4→Ser, Thr5→Ser, and Phe6→Trp) compared with human ET-2, demonstrating that the structure of the peptide has been well conserved during evolution and that the pathway of posttranslational processing of preproendothelin in the trout is probably similar to that in mammals. Synthetic trout ET produced concentration-dependent constrictions of isolated rings of vascular tissue from trout efferent branchial artery (EBA; pD2 = 7.90 ± 0.06, n = 5), caeliacomesenteric artery (pD2 = 8.03 ± 0.04, n = 4), anterior cardinal vein (ACV; pD2 = 8.57 ± 0.25, n = 4), and rat abdominal aorta (AO; pD2 = 8.86 ± 0.08, n = 7). Trout and rat vessels were more sensitive to mammalian ET-1 than to trout ET (pD2 for human ET-1 in: EBA = 9.12 ± 0.14; ACV = 9.90 ± 0.15; AO = 8.86 ± 0.08), but there was no significant difference in the maximum tension produced by either peptide in these vessels.

In an animal model, the American eel, perifused elastic arteries and large veins, but not the heart and organs with extensive microvascular supply (gills and opisthonephric kidney), release spontaneously free dopamine. Only the region of the cardinal vein, which contains the adrenomedullary equivalent, also releases norepinephrine (NE) and epinephrine (E). Ca2+, KCl, and E stimulate dopamine release from the ventral aorta and caudal vein, indicating that this phenomenon is due to secretion and not to washout. E also stimulates NE release from the ventral aorta and caudal vein. In the rat, both aorta and vena cava spontaneously release dopamine and NE. Thus dopamine secretion from large blood vessels may be general in vertebrates. The dopamine response to high physiological concentrations of E in vivo and in vitro suggests that macrovascular dopamine may be involved in local stress responses.

Device Placement

Persistent left superior vena cava is the most common congenital anomaly of thoracic venous return, which results when the left anterior cardinal vein fails to regress. A 41-year-old African American male with a history of an unspecified childhood cardiac murmur presented to the emergency department with congestive heart failure exacerbation revealing an incidental finding of a persistent left superior vena cava. Ultimately, he required implantable cardioverter defibrillator placement and cardiac transplantation assessment. In the setting of advanced device placement or cardiac transplantation, a persistent left superior vena cava warrants several important clinical considerations at a center capable of addressing the possibility of a right-sided approach and transplantation irregularities.

Abstract During embryonic development, lymph sacs form from the cardinal vein, and sprout centrifugally to form mature lymphatic networks. Separation of the lymphatic from the blood circulation by a hitherto unknown mechanism is essential for the homeostatic function of the lymphatic system. O-glycans on the lymphatic endothelium have recently been suggested to be required for establishment and maintenance of distinct blood and lymphatic systems, primarily by mediating proper function of podoplanin. Here, we show that this separation process critically involves platelet activation by podoplanin. We found that platelet aggregates build up in wild-type embryos at the separation zone of podoplanin+ lymph sacs and cardinal veins, but not in podoplanin−/− embryos. Thus, podoplanin−/− mice develop a “nonseparation” phenotype, characterized by a blood-filled lymphatic network after approximately embryonic day 13.5, which, however, partially resolves in postnatal mice. The same embryonic phenotype is also induced by treatment of pregnant mice with acetyl salicylic acid, podoplanin-blocking antibodies, or by inactivation of the kindlin-3 gene required for platelet aggregation. Therefore, interaction of endothelial podoplanin of the developing lymph sac with circulating platelets from the cardinal vein is critical for separating the lymphatic from the blood vascular system.
