Abstract

Insights

This study presents a refined technique for treating spontaneous isolated dissection of the superior mesenteric artery (SIDSMA) using a Flexor introducer. The method achieved high technical success and positive early-to-medium term outcomes for SIDSMA repair.

Area of Science:

  • Vascular Surgery
  • Interventional Radiology
  • Gastroenterology

Background:

  • Spontaneous isolated dissection of the superior mesenteric artery (SIDSMA) is a rare condition with controversial treatment options.
  • Endovascular stenting is a potential treatment modality for SIDSMA.

Purpose of the Study:

  • To present a refined endovascular technique using a Flexor introducer for stent advancement in SIDSMA.
  • To evaluate the early to medium-term outcomes of this refined technique.

Main Methods:

  • Retrospective analysis of 16 male patients with SIDSMA treated with endovascular stenting (January 2012-December 2017).
  • Diagnosis confirmed by computed tomography angiography.
  • A Flexor introducer was used to facilitate coaxial stent delivery into the true lumen of the dissected superior mesenteric artery.

Main Results:

  • Technical success rate of 87.5% (14 out of 16 patients).
  • Successful stenting achieved in 14 cases; two failures due to extensive thrombus.
  • All successfully stented superior mesenteric arteries remained patent at follow-up (median 17 months).
  • Postoperative abdominal pain resolved in most patients.

Conclusions:

  • Coaxial stent delivery with a Flexor introducer offers high technical success and favorable clinical outcomes for SIDSMA.
  • Extensive thrombus is the primary factor limiting endovascular treatment success in SIDSMA.

Spontaneity02:21

Spontaneity

A spontaneous process is one that occurs naturally under certain conditions. A nonspontaneous process, on the other hand, will not take place unless it is “driven” by the continual input of energy from an external source. Processes have a natural tendency to occur in one direction under a given set of conditions. Water will naturally flow downhill (spontaneous process), but uphill flow (nonspontaneous process) requires outside intervention such as the use of a pump. Iron exposed to...

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.

Spontaneous and Induced Mutations01:30

Spontaneous and Induced Mutations

Spontaneous mutations arise infrequently during DNA replication due to errors in the process. A key factor behind these errors is tautomeric shifts in nitrogenous bases, where bases transition from keto to enol forms or amino to imino forms. This shift can alter base-pairing rules, leading to mutations. Additionally, reactive oxygen species (ROS) arising from aerobic metabolism can damage DNA, resulting in depurination (loss of a purine base) or depyrimidination (loss of a pyrimidine base).

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...
