Insights

Percutaneous stenting effectively manages chronic ischemia from endograft limb occlusion after EVAR. This safe procedure offers good long-term symptom relief and maintains stent patency.

Area of Science:

  • Vascular Surgery
  • Endovascular Interventions
  • Aortic Aneurysm Repair

Background:

  • Endovascular aortic aneurysm repair (EVAR) can lead to endograft limb occlusion, causing chronic ischemia.
  • Management options for this complication require investigation for safety and efficacy.

Purpose of the Study:

  • To evaluate the safety and efficacy of percutaneous stenting for chronic ischemia resulting from EVAR limb occlusion.

Main Methods:

  • Retrospective, single-center study of patients with EVAR limb occlusion treated with percutaneous stenting (covered or bare metal).
  • Exclusion of acute limb ischemia cases treated surgically.
  • Primary outcomes: technical success, symptom-free interval. Secondary outcomes: target-lesion reintervention (TLR)-free survival, primary patency, complications.

Main Results:

  • 11 patients with chronic ischemia (10 intermittent claudication, 1 rest pain) underwent stenting.
  • Technical success achieved in 90% of cases with no major complications.
  • At 5-year follow-up, symptom-free interval and primary patency were 83.33%; TLR-free survival was 100%.

Conclusions:

  • Percutaneous stenting is a safe and feasible treatment for chronic ischemia due to EVAR limb occlusion.
  • Satisfactory long-term outcomes, including patency and symptom relief, were observed.
  • Careful patient selection is crucial for achieving clinical success.

Predicting Reaction Outcomes02:24

Predicting Reaction Outcomes

Kinetics describes the rate and path by which a reaction occurs. In contrast, thermodynamics deals with state functions and describes the properties, behavior, and components of a system. It is not concerned with the path taken by the process and cannot address the rate at which a reaction occurs. Although it does provide information about what can happen during a reaction process, it does not describe the detailed steps of what appears on an atomic or a molecular level. On the other hand,...

Outcomes of Glycolysis01:13

Outcomes of Glycolysis

Nearly all the energy used by cells comes from the bonds that make up complex organic compounds. These organic compounds are broken down into simpler molecules, such as glucose. As a result, cells extract energy from glucose over many chemical reactions—a process called cellular respiration.
Cellular respiration can occur aerobically (with oxygen) or anaerobically (without oxygen). In the presence of oxygen, cellular respiration starts with glycolysis and continues with pyruvate...

Long-term Depression01:05

Long-term Depression

Long-term depression, or LTD, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTD is the process of synaptic weakening that occurs over time between pre and postsynaptic neuronal connections. The synaptic weakening of LTD works in opposition to synaptic strengthening by long-term potentiation (LTP) and together are the main mechanisms that underlie learning and memory.

Arteries of Lower Limbs01:20

Arteries of Lower Limbs

The external iliac artery transitions out of the body cavity, entering the femoral region of the lower leg, and is renamed the femoral artery at the point where it traverses the body wall. This artery is responsible for the distribution of blood to the thigh's deep muscles and the skin's ventral and lateral regions, achieved through several minor branches and the lateral deep femoral artery, which also spawns a lateral circumflex artery. The knee area receives blood from the genicular...

Veins of Lower Limbs

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...

Guidelines for Writing Outcome01:11

Guidelines for Writing Outcome

When developing expected outcomes for a patient care plan, the nurse should adhere to the following recommendations:
Patient outcomes reflect the patient's response to the goal rather than what the nurse aims to achieve. Terminology should be observable and measurable to avoid the reader's interpretation. The desired outcome should be realistic and achievable in the designated care timeframe. Expected outcomes should align with adjunctive therapies. The outcome should enhance care...
