Tīmeklis2024. gada 21. febr. · The RA myocardium has extensions into the SVC, although typically muscle is absent in the IVC. Muscle sleeves are seen in three-quarters of SVCs, extending a mean distance of 4 mm (3.8 ± 9.4 mm) above the orifice. Two-fifths of extensions into the SVC have a symmetric circumferential sleeve of muscle rather … TīmeklisCVCs placed for the purpose of long term chemotherapy may be placed more inferiorly at the cavo-atrial junction - the junction of the SVC and right atrium (RA).
