Animal models of atherosclerosis are essential to understand the mechanism and to investigate newer approaches to prevent plaque development or rupture, a leading cause of death in the industrialized world. This protocol uses a combination of balloon injury and cholesterol rich diet to induce atherosclerotic plaques in rabbit iliac artery.

This manuscript provides the detailed procedure of intra-iliac artery (IIA) injection, a technique to deliver cancer cells specifically to hind limb tissues including bones to establish experimental bone metastases. Although initially established with breast tumor models, this protocol can be easily extended to other cancer types.

In order to accurately calculate the concentration of an unknown from a sample, careful sample preparation is key. Every time a sample is handled or transferred, some of the sample can be lost. There are strategies however, for minimizing sample loss. There are also strategies for coping with sample loss and...

Internal Energy

The total of all possible kinds of energy present in a substance is called the internal energy (U), sometimes symbolized as E. Suppose a system with initial internal energy, Uinitial, undergoes a change in energy (transfer of work or heat), and the final internal energy of the system is Ufinal. Change in internal energy equals the difference between Ufinal and Uinitial. Although the values for Ufinal and Uinitial cannot be determined for a system, the first law of thermodynamics only...

Central Venous Catheter Insertion: Femoral Vein

Source: James W Bonz, MD, Emergency Medicine, Yale School of Medicine, New Haven, Connecticut, USA Central venous access is necessary in a multitude of clinical situations, including vascular access, vasopressor and caustic medication delivery, central venous pressure monitoring, volume resuscitation, total parental nutrition, hemodialysis, and frequent phlebotomy. There are three veins in the body that are accessed for central venous cannulation: the internal jugular, the subclavian, and the...
FAQs
The vessel forms from the union of venous tributaries draining pelvic organs, pelvic walls, the gluteal region, and the perineum. This converging arrangement collects blood from several anatomically connected areas before the vessel ascends alongside the internal iliac artery. It then joins the external iliac vein near the sacroiliac joint, establishing the pathway toward the common iliac vein.
With valves generally absent, blood can move through interconnected pelvic veins in more than one direction when pressure conditions change. This arrangement supports collateral circulation, meaning alternate venous routes can help maintain drainage. The same connectivity also creates potential pathways through which pelvic disease or thrombus may extend between regions rather than remaining confined to one drainage channel.
Anastomoses connect neighboring veins and create a network rather than an isolated drainage route. Functionally, these connections can provide alternative pathways for venous return if one route is compromised. Clinically, however, the network may also facilitate movement of disease or thrombus across pelvic regions, making the pattern of venous communication important when interpreting pelvic pathology.
The vein travels upward along the internal iliac artery, providing an important anatomical relationship for identifying it within the pelvis. Recognizing this paired course helps organize the venous anatomy relative to nearby pelvic structures. The vein’s later union with the external iliac vein near the sacroiliac joint also helps establish the transition to the common iliac vein.
Pelvic imaging relies on understanding the vein’s tributaries, upward course beside the internal iliac artery, and connection with the external iliac vein. Its extensive venous communications can influence how normal drainage and abnormal spread appear across pelvic regions. This anatomical framework supports interpretation of venous disorders and helps distinguish interconnected pathways from isolated vascular findings.
Its location, tributary connections, and generally valveless network make the vessel relevant wherever pelvic structures are evaluated or treated. Surgeons and clinicians must understand these relationships to interpret pelvic vascular anatomy, while obstetric assessment may require attention to the same venous pathways. The anatomy also provides context for evaluating pelvic venous disorders and collateral circulation.
