Targeting Liver Tumors with Oncolytic Viruses via the Hepatic Artery

The video demonstrates locoregional delivery of oncolytic viruses through hepatic arterial injection as a therapeutic approach for hepatocellular carcinoma. These viruses selectively replicate in tumor cells, inducing cell lysis and releasing tumor cell-associated antigens. This process triggers immunogenic cell death, inducing an anti-tumor response.

We describe a highly reproducible method for the permanent occlusion of a rodent major cerebral blood vessel. This technique can be accomplished with very little peripheral damage, minimal blood loss, a high rate of long-term survival, and consistent infarct volume commensurate with the human clinical population.

After spinal transection, adult zebrafish have functional recovery by six weeks post-injury. To take advantage of larval transparency and faster recovery, we present a method for transecting the larval spinal cord. After transection, we observe sensory recovery beginning at 2 days post-injury, and C-bend movement by 3 days post-injury.

Direct Re-implantation of Left Coronary Artery into the Aorta in Adults with Anomalous Origin of Left Coronary Artery from the Pulmonary Artery (ALCAPA)

Surgical correction of ALCAPA is highly recommended, regardless of age or the degree of intercoronary collateralization. This protocol presents a technique for the direct re-implantation of adult-type ALCAPA into the aorta to re-establish the dual-coronary perfusion. Whenever feasible, direct re-implantation is preferred to other surgical correction techniques.

Heterotopic Auxiliary Rat Liver Transplantation With Flow-regulated Portal Vein Arterialization in Acute Hepatic Failure

Auxiliary liver transplantation provides a temporary support in acute hepatic failure, until regeneration of the failing liver. The heterotopic auxiliary liver transplantation (HALT) with portal vein arterialization (PVA) renders sufficient liver function. We developed an analogous technique in the rat, to examine the influence of the portal vein arterialization on the morphology and function of the graft.
FAQs
Bleeding can become substantial because transection interrupts arterial flow from a vessel supplying several upper abdominal territories, including portions of the stomach, duodenum, and pancreas. The consequence depends on whether division is controlled or accidental: planned interruption is incorporated into the operation, whereas unrecognized injury may produce intraoperative or gastrointestinal hemorrhage requiring prompt control.
The gastroduodenal artery arises from the common hepatic artery, so recognizing this relationship helps surgeons plan exposure and division without losing orientation. Its connections with structures supplying the stomach, duodenum, and pancreas also make preservation of nearby anatomy important. Careful identification supports safer operative planning and reduces the chance that an unintended injury will remain unrecognized.
Collateral circulation provides an important anatomic consideration when the artery is divided. Surgeons therefore aim to control the transected vessel while preserving nearby structures and existing collateral pathways. This balance allows the operation to achieve access or hemostasis without unnecessarily disrupting other sources of arterial supply to the surrounding upper abdominal tissues.
Control begins with exposing the vessel clearly enough to identify and manage both transected ends. Each end is then secured with an appropriate method, such as ligatures, clips, or vascular sutures. During this process, the surgeon protects nearby structures and avoids avoidable disruption of collateral circulation, supporting effective hemorrhage control and safer completion of the procedure.
Planned transection may be used to provide surgical access during pancreaticoduodenectomy and other upper abdominal procedures. In that setting, division is incorporated into the operative plan and followed by deliberate control of both vessel ends. The same event becomes an emergency concern when it occurs unintentionally or is not recognized, because significant bleeding can develop.
An unrecognized injury can cause life-threatening bleeding during the operation or present as gastrointestinal hemorrhage afterward. This possibility makes knowledge of the artery's anatomy relevant beyond the moment of transection: surgeons must support rapid identification and vessel control while protecting adjacent structures. Effective management is intended to improve postoperative outcomes and limit hemorrhagic complications.
