 | | The external jugular vein descends toward the chest just deep to the skin on the anterior surface of the sternocleidomastoid muscle. | | | Lumbar veins drain the lumbar portion of the abdomen, including the spinal cord and body wall muscles. | | | In contrast, the neck and limbs generally have two sets of peripheral veins, one superficial and the other deep. |

| | Surgery of the Superior Vena Cava: Resection And Reconstruction - Venuta |
| | Revascularization of both systems is indicated in case of previous neck surgery (laryngeal or thyroid surgery for cancer); a separate distal anastomosis of the two grafts is preferred to avoid thrombosis of the accessory left limb of a Y graft, starting at the level of the graft–to–graft anastomosis. | | | Palliative bypass: the indications for palliative procedures of bypass are extremely rare due to the low venous blood flow obtained from the axillary or jugular veins. Surgically created A–V fistulae devoted to increase flow through the bypass conduit are generally unsuccessful. | | | A careful functional evaluation should be performed (PFTs and arterial blood gas analysis) since a relevant number of patients with right upper lobe lung cancer invading the SVC are candidates for standard pneumonectomy or pneumonectomy with carinal resection. |

| | Prosthetic Replacement of the Superior Vena Cava |
| | Despite revascularization of the SVC might be performed using either jugular or axillary veins, this usually results in a low venous blood flow through the graft and long prosthesis (passing subcutaneously with major kinkings and thrombosis risks); even surgical created artero-venous fistulae aiming to increase the flow through the graft are unsuccessful. | | | i) Shunt procedures: intraluminal shunting of the blood from the brachiocephalic vein into the right atrium may re duce the hemodynamic consequences of venous clamping. | | | Indications for revascularization of both brachiocephalic veins are extremely rare and confined only to those patients whose right or left-sided internal jugular vein is absent because of previous neck surgery (e.g. |

| | In most cases the two septa physically fuse leaving evidence of the former foramen ovalis as a shallow depression, the fossa ovalis, when viewed from within the right atrium. | | | The development of this left brachiocephalic vein allows the drainage of all blood from the left upper extremity and head and neck into the right atrium. | | | Conduction system - Myocytes within the developing heart tube develop a more rapid rate of spontaneous depolarization to produce two pacemaker regions, the sinoatrial node (regulating atrial rhythm) and an atrioventricular node connected by a myocardial conduction pathway (most notably within the crista terminalis) to coordinate regulate ventricular rhythmicity through the bundle of His. |

| | In patients with malignancy, obstruction of the superior vena cava and its tributaries is commonly encountered (1, 2); benign causes such as central venous catheters, high-flow states associated with hemodialysis access fistulas, intravenous pacemaker wires, and mediastinal fibrosis are less common. | | | Although some flow artifacts were present in contralateral central veins and the superior vena cava, the information derived from CT venography was sufficient for diagnosis and treatment, and on the basis of the observed pattern of opacification of collateral and central veins, an understanding of the venous hemodynamics involved was facilitated. | | | First, because patients in whom a venous lesion was diagnosed at CT venography underwent digital subtraction venography, it was affected by selection bias: a patient with a negative CT venogram and a positive digital subtraction venogram could not be included. |
