We describe a method for creating a reliable model of cerebral venous hypertension in the adult mouse. This model has been widely described and tested in the rat. This new counterpart in the mice opens the possibility of using genetic modified animals and thereby broadens the applications of the model.

Veins are an integral part of our circulatory system, serving as the blood vessels that transport blood from all body regions to the heart. They are a network of hollow tubes that carry blood low in oxygen from the body's cells back to the heart for reoxygenation. Veins are crucial for maintaining the body's overall fluid balance and the continuous circulation of blood. Structure of Veins: The structure of veins is specifically designed to assist in the low-pressure transportation of blood...

2025
We present a laparoscopic technique for anatomic S7+S8d resection with right hepatic vein transection, preserving the inferior right hepatic vein and segment S6. Relying on meticulous anatomical landmarks without intraoperative ultrasound, this approach offers a precise and parenchyma-sparing option for dorsally located right-liver tumors, particularly in settings with limited advanced navigation resources.

The azygos system is a crucial part of the body's circulatory system and drains most of the thorax. It comprises the azygos, hemiazygos, and accessory hemiazygos veins. The azygos vein, positioned just right of the midline and anterior to the vertebral column, begins at the junction of the right ascending lumbar and subcostal veins, terminating in the superior vena cava. This vein drains blood from the right side of the thoracic wall, thoracic viscera, and posterior abdominal wall. The...

The human body consists of an intricate network of veins responsible for the crucial task of blood drainage from the lower limbs. These veins can be categorized into two main types: deep veins and superficial veins. Formed by the union of the medial and lateral plantar veins, the posterior tibial vein, rising through the calf muscle, assimilates the fibular vein. The anterior tibial vein, a superior extension of the foot's dorsalis pedis vein, merges with the posterior tibial vein at the knee,...
FAQs
Preserving the inner endothelial lining supports a continuous vessel surface at the repair site. Damage or poor alignment can interfere with venous flow and contribute to thrombosis, which may compromise drainage through the reconstruction. This principle is especially important in microsurgical procedures, where dependable outflow directly supports the survival of transferred or replanted tissue.
Twisting, narrowing, and obstruction can restrict venous flow after the vessel ends are connected. These problems may arise when the vessel alignment is not maintained or when the reconstructed channel is inadequately shaped. Careful handling and inspection of the connection are therefore essential for maintaining patency and reducing conditions that promote thrombosis.
Fine sutures and vascular couplers provide two ways to connect the vessel walls after the vein ends are aligned. Both approaches must maintain the endothelial surface and preserve an unobstructed lumen. The choice of connection method is relevant in microsurgery because reliable construction helps maintain venous drainage and supports evaluation of the completed anastomosis.
The technique has an important role in microsurgery, including free-tissue transfer and replantation, as well as selected vascular reconstructions. In these settings, the repaired venous pathway provides drainage from the affected or transferred tissue. Adequate drainage is clinically significant because tissue survival depends on a functioning vascular connection rather than arterial supply alone.
Postoperative assessment focuses on anastomotic patency and venous flow. These evaluations help determine whether blood can pass through the reconstructed segment without clinically important obstruction. Detecting impaired flow or loss of patency can identify complications early, allowing the surgical team to evaluate the repair and use the findings to improve subsequent outcomes.
Reliable venous drainage helps preserve the viability of tissue used in free-tissue transfer or replantation. If the anastomotic pathway becomes narrowed, twisted, obstructed, or thrombosed, outflow may be compromised and tissue survival may be threatened. Monitoring postoperative flow therefore connects the technical quality of the repair with the broader success of reconstruction.
