Insights

Primary stenting for hepatic artery stenosis (HAS) in liver transplant patients shows excellent long-term patency. This approach resulted in a 90% primary patency rate at one year with minimal need for reintervention.

Area of Science:

  • Hepatology
  • Transplant Surgery
  • Interventional Radiology

Background:

  • Hepatic artery stenosis (HAS) is a common complication after liver transplantation.
  • High reintervention rates are reported after primary stenting for HAS due to loss of primary patency.

Purpose of the Study:

  • To evaluate the long-term outcomes of primary stenting for HAS in a large cohort of liver transplant recipients.
  • To assess primary patency and reintervention rates following endovascular treatment of HAS.

Main Methods:

  • Retrospective evaluation of liver transplant patients (2003-2017) for HAS.
  • HAS defined as >50% stenosis on imaging.
  • Primary stenting attempted in 30 patients; outcomes assessed annually.

Main Results:

  • Technical success rate for primary stenting was 97%.
  • Primary patency was 90% at 1 year and maintained throughout the follow-up period (median 41 months).
  • Only 3 patients required reintervention; no major complications or hepatic artery thrombosis occurred.

Conclusions:

  • Primary stenting for HAS in liver transplant recipients offers excellent long-term patency.
  • This endovascular approach is associated with low reintervention rates and a favorable safety profile.

Primary Active Transport01:47

Primary Active Transport

In contrast to passive transport, active transport involves a substance being moved through membranes in a direction against its concentration or electrochemical gradient. There are two types of active transport: primary active transport and secondary active transport. Primary active transport utilizes chemical energy from ATP to drive protein pumps that are embedded in the cell membrane. With energy from ATP, the pumps transport ions against their electrochemical gradients—a direction...

Primary and Secondary Growth in Roots and Shoots

Vascular plants, which account for over 90% of the Earth’s vegetation, all undergo primary growth—which lengthens roots and shoots. Many land plants, notably woody plants, also undergo secondary growth—which thickens roots and shoots.

Primary Production01:06

Primary Production

The total amount of energy acquired by primary producers in an ecosystem is called gross primary production (GPP). However, of this energy, producers use some for metabolic processes, and some is lost as heat, decreasing the amount of energy available to the next trophic level. The remaining usable amount of energy is called the net primary productivity (NPP). In terrestrial ecosystems, NPP is driven by climate, while light penetration and nutrient availability drive NPP in aquatic ecosystems.

Primary Distribution01:28

Primary Distribution

Primary distribution systems deliver electrical power from substations to consumers through various voltage classes, with 15-kV class voltages being predominant among U.S. utilities. Older 2.5- and 5-kV classes are being replaced by 15-kV primaries, while higher 25- to 34.5-kV classes are used in high-density urban areas and rural regions with long feeders. Three-phase, four-wire multigrounded systems are widely employed for balanced power delivery, using the neutral wire as a grounding point.

Nomenclature of Primary Amines01:17

Nomenclature of Primary Amines

Primary, secondary, and tertiary amines are compounds consisting of one, two, and three alkyl groups connected to the amino group (–NH2), respectively. As depicted in Figure 1, the common name of the primary amines is obtained by adding the suffix -amine to the alkyl substituent attached to the amino group as the corresponding alkylamine.
