The arterial supply of the gallbladder usually arises from the right hepatic artery. Other origins include the left, proper, and common hepatic arteries. We report cases of the cystic artery arising from the superior mesenteric artery and arising from the dorsal pancreatic artery originating in turn from the superior mesenteric artery, as demonstrated by angiography and computed tomography.

Swarming micro/nanorobots offer great promise in performing targeted delivery inside diverse hard-to-reach environments. However, swarm navigation in dynamic environments challenges delivery capability and real-time swarm localization. Here, we report a strategy to navigate a nanoparticle microswarm in real time under ultrasound Doppler imaging guidance for active endovascular delivery. A magnetic microswarm was formed and navigated near the boundary of vessels, where the reduced drag of blood flow and strong interactions between nanoparticles enable upstream and downstream navigation in flowing blood (mean velocity up to 40.8 mm/s). The microswarm-induced three-dimensional blood flow enables Doppler imaging from multiple viewing configurations and real-time tracking in different environments (i.e., stagnant, flowing blood, and pulsatile flow). We also demonstrate the ultrasound Doppler–guided swarm formation and navigation in the porcine coronary artery ex vivo. Our strategy presents a promising connection between swarm control and real-time imaging of microrobotic swarms for localized delivery in dynamic environments.

The present work is an anatomical demonstration of the collateral blood supply which maintains the liver after acute interruption of the hepatic artery. This is demonstrated with x-ray films and corrosion specimens of the livers of dogs weeks to months following excision of the hepatic artery. The livers were injected with red lead suspension or with a plastic material. With both methods, we have demonstrated the development of adequate anastomoses within the liver between the phrenic and the hepatic arteries. The phrenic arteries had hypertrophied considerably and numerous good sized anastomoses with the hepatic arteries were present, allowing for an adequate supply of arterial blood to the liver and survival of the animal. In similar control experiments on normal dogs, the phrenic arteries were small, and insignificant anastomoses to the hepatic arteries were found.

AbstractArterial supply for the derivatives of foregut in the abdomen is provided by the branches of the celiac trunk. Celiac trunk is the first ventral branch of abdominal aorta and usually branches into splenic, common hepatic and left gastric arteries. Variations in the branching pattern of celiac trunk are common but in most of the people, they remain asymptomatic and go unnoticed. A good knowledge of these anatomical variations is important for surgeons undertaking various surgeries in the abdominal region and will help to minimise the complications related to abdominal surgery. Clinicians and radiologists should also be aware of any variations in the vascular pattern of the celiac trunk before performing angiographic examinations. In the current case, the celiac trunk divided into two branches; left gastric artery and hepato-splenic trunk. The hepato-splenic trunk further divided into splenic and common hepatic arteries. The common hepatic artery trifitrcated into proper hepatic, gastroduodenal and accessory hepatic arteries. Hepatic artery proper divided into right and left hepatic arteries. The accessory hepatic artery was tortuous and was as large as the left hepatic artery. It gave origin to the right gastric artery and entered the liver through left end of porta hepatis.
