Small bowel obstructions (SBOs) are a known perioperative complication of laparoscopic Roux-en-Y gastric bypass and common etiologies include internal hernia, port site hernia, jejunojejunostomy stricture, ileus and adhesions. Less commonly, SBO can be caused by superior mesenteric artery syndrome, intussusception and intraluminal blood clot. We present a case of SBO caused by intraluminal bloo...

fluid. Many different fluids have been employed for this purpose, the one we prefer being Vibert's fluid (Common salt 2 grammes, Mercury Perchloride 0.5 gramme, Distilled water 100 c.c.). The clot is soaked in a few drops of Vibert's fluid in a watch glass for twenty minutes, care being taken to avoid evaporation. Then a portion of the softened clot is gently teased and transferred to a slide b...

Atrial fibrillation (AF) is the most common sustained dysfunction in heart rhythm clinically and has been identified as an independent risk factor for stroke through formation and embolization of thrombi. AF is associated with reduced cardiac output and short and irregular cardiac cycle length. Although the effect of AF on cardiac hemodynamic parameters has been reported, it remains unclear how...

The blood of Limulus polyphemus L. has been shown to contain the protein haemocyanin and white corpuscles. The blood clots with great rapidity. Loebl found that clotting is not preventable by the usual chemical methods but only by methods which prevent agglutination of the corpuscles. Further, Loeb has shown that the clot is formed by the agglutination of the corpuscles, indicating the absence ...

During surgical procedures, abdominal swabs are routinely used to adsorb blood from the operation field and for the retention of tissues and organs. Due to the material characteristics, abdominal swabs exhibit a slight procoagulant activity, which is usually desirable and mostly harmless. However, during cardiac surgery with heart-lung machine (HLM) support, abnormal clot formation may result i...

Hemostatic plug covering the injury site (or a thrombus in the pathological case) is formed due to the complex interaction of aggregating platelets with biochemical reactions in plasma that participate in blood coagulation. The mechanisms that control clot growth and which lead to growth arrest are not yet completely understood. We model them with numerical simulations based on a hybrid DPD-PDE...

Application of low-frequency ultrasound for clot disruption has been suggested as a potential therapy to enhance thrombus dissolution, but the optimal mode for delivery of ultrasound with clot-disruptive properties has not yet been extensively explored. Target-specific effects are desirable and may be accomplished by focusing the ultrasound. Adequate focusing, however, requires a short waveleng...

BACKGROUND AND PURPOSE To date, there is no immediate radiographic surrogate to quantify primary cerebral injury to identify patients at risk for delayed cerebral ischemia and poor clinical outcome after aneurysmal subarachnoid hemorrhage. Therefore, we investigated the relation of early cerebral perfusion-computerized tomography and clot volume with radiological events of delayed cerebral isch...

Coordinated enzymatic reactions regulate blood clot generation. To explore the contributions of various coagulation enzymes in this process, we utilized a panel of aptamers against factors VIIa, IXa, Xa, and prothrombin. Each aptamer dose-dependently inhibited clot formation, yet none was able to completely impede this process in highly procoagulant settings. However, several combinations of tw...
