概括

手术后的抗凝药并没有改善化保存的静脉移植在下 inguinal 绕道的结果. 然而,抗血小板药物与更好的结果有关,这表明它们的使用超过抗凝药来改善移植通透性.

科学领域:

血管外科血管外科
心血管医学心血管医学
再生医学是一种再生医学.

背景情况:

低温保存的静脉移植用于当自身静脉不足时的内绕道.
由于相互矛盾的证据,抗凝剂在改善这些移植的结果方面的有效性仍在争论中.

研究的目的:

评估术后抗凝剂对用冷保存的静脉移植进行下 inguinal 绕道术的患者的结果的影响.
为了比较接受抗凝药和不接受抗凝药的患者之间的结果.

主要方法:

来自血管质量倡议 (2003-2022) 的数据分析,用于使用冷保存的静脉移植进行下 inguinal 绕道.
基线特征,手术细节和退院患者与不使用抗凝药之间的结果的比较.
应用单变量,卡普兰-梅尔和多变量分析来评估结果.

主要成果:

手术后的抗凝药在1年内没有显著改变初级通透性,重大截肢/死亡,或重新干预/重大截肢/死亡率.
接受抗凝剂治疗的患者的生存率更高 (85.1% vs 81.7%,P = .03).
抗血小板药物 (阿司匹林和P2Y12抑制剂) 与截肢/死亡和重新干预/重大截肢/死亡率的降低有关.

结论:

手术后的抗凝剂不会增强透性或在下内绕道下使用冷保存的静脉移植中挽救四肢.
抗血小板治疗与改善的结果有关,因此应考虑冷保存的移植通透性.
整体而言,一年的穿透率和肢体救援率仍然不够理想,这凸显了需要进一步研究和改进策略的需要.

关键词:

慢性肢体威胁性缺血症可能会导致肢体缺血.在冷保存下保存.缺血缺血是因为缺血.这是一种抗凝血药物.

Anticoagulant Drugs: Low-Molecular-Weight Heparins

Hemostasis is a crucial process that prevents excessive blood loss from damaged blood vessels. It involves various mechanisms such as vasoconstriction, platelet adhesion and activation, and fibrin formation. The importance of each mechanism depends on the type of vessel injury. In contrast, thrombosis is the abnormal formation of a blood clot within the blood vessels, leading to potential complications if the clot obstructs blood flow. Thrombosis can be caused by increased coagulability of the...

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.
One of the advantages of...

Veins of Lower Limbs

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...
