Insights

Open distal venous arterialization (DVA) offers a feasible, low-cost solution for limb salvage in chronic limb-threatening ischemia (CLTI) patients. This technique demonstrated promising limb salvage and graft patency rates in a Latin American cohort.

Area of Science:

  • Vascular Surgery
  • Reconstructive Surgery

Background:

  • Chronic limb-threatening ischemia (CLTI) significantly impacts quality of life, leading to amputation and mortality.
  • Effective limb salvage strategies are crucial for managing CLTI patients.

Purpose of the Study:

  • To evaluate the outcomes of open distal venous arterialization (DVA) for limb salvage in CLTI patients.
  • To assess the feasibility and effectiveness of DVA in a Latin American setting.

Main Methods:

  • Retrospective case series of 5 CLTI patients from Bogotá, Colombia (2018-2022).
  • Open DVA procedures were performed, with a 12-month follow-up.
  • Data collected included operative time, length of stay, graft type, re-interventions, patency, amputations, and mortality.

Main Results:

  • 80% graft patency was observed at 1 year.
  • One major amputation and two minor amputations were performed.
  • No perioperative mortality, but one late mortality from myocardial infarction.

Conclusions:

  • Open DVA is a viable and cost-effective technique for selected CLTI patients with suitable saphenous veins.
  • The study highlights successful limb salvage and graft patency in a high-volume CLTI center.

Local Anesthetics: Clinical Application as Intravenous Regional Anesthesia

Intravenous regional anesthesia or the Bier block technique is used to anesthetize a specific limb or extremity. It uses exsanguinated or blood-drained vessels to transport local anesthetics or LAs to the peripheral nerve trunks. Lidocaine without vasoconstrictors like epinephrine is most commonly used for this technique. Other drugs used are prilocaine, ropivacaine, and chloroprocaine. Bupivacaine is not recommended for this technique due to its high cardiac toxicity.

Assessment of the Cardiovascular System III: Palpation

Palpation involves feeling the body to evaluate texture, size, consistency, and tenderness for assessing cardiovascular health. The following steps are organized in a head-to-toe order:
Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above...

Veins of Lower Limbs01:15

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...
