Source: Sharon Bord, MD, Department of Emergency Medicine, The Johns Hopkins University School of Medicine, Maryland, USA Placement of an intravenous (IV) catheter is one of the key procedures in medicine. The IV catheter allows patients to receive critical medications, including pain medicine, insulin, antibiotics, blood products, and fluids for rehydration. Additionally, placing an IV catheter allows for blood samples to be obtained, which can be sent to the laboratory for testing and...

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.

This video demonstrates intraduodenal cannulation in a rat model. After anesthetizing the rat, the duodenum is located and a small puncture is created. A J-shaped cannula with a beveled tip is carefully inserted and secured, and the incision is closed. The cannulated rat model enables intra-intestinal infusion for immunopathology studies.

A protocol for the cannulation of the mouse submandibular salivary gland via the Wharton's duct is described. For this experiment, the trypan blue solution is used as a dyer to demonstrate how this technique effectively delivers infusions into the targeted gland, and to suggest the reliability of this new approach as a potential clinical drug/cell therapy for the regeneration of salivary glands.

FAQs
Blood collected from the splenic vein reflects venous drainage from the spleen before it mixes more broadly within the portal circulation. This makes the access point useful for examining splenic contributions to portal hemodynamics and for studying substances released by splenic tissue. The resulting measurements can provide information that may be less specific when obtained from systemic venous blood.
The catheter permits direct measurement of pressure within the splenic venous pathway, creating a focused view of pressures associated with splenic drainage and portal circulation. In studies of portal hypertension, these measurements can help characterize altered portal hemodynamics. The technique therefore complements broader clinical or experimental assessments by providing information from a defined vascular location.
Splenic venous blood has passed through the spleen, so its composition may reflect substances released by that organ. Sampling at this location can help investigators examine splenic function and distinguish splenic contributions within the portal circulation. This organ-specific access is particularly relevant when the research question concerns products or changes associated with the spleen itself.
Access must be established under carefully controlled surgical or image-guided conditions so the catheter reaches the intended vessel and remains usable for the planned measurement or intervention. Guidance helps support accurate placement, while controlled vascular access allows blood sampling, pressure measurement, or agent delivery. The selected approach depends on the clinical or research setting described by the protocol.
Bleeding and other vascular complications are the principal concerns highlighted for this technique. Because the catheter enters a blood vessel, placement and subsequent handling require careful guidance and management. Monitoring for these complications is essential to preserve controlled access and to ensure that measurements, samples, or delivered agents do not compromise the vascular system.
Researchers may choose splenic vein cannulation when they need information specifically linked to splenic drainage, portal pressure, or substances released by the spleen. It can support investigations of splenic function and portal hemodynamics, while also allowing controlled delivery of agents into the relevant vascular pathway. Its value is greatest when organ-specific access is central to the study question.
