Dilution Curves

The role of venous passage of indicator from different venous injection sites on the genesis of right heart and pulmonary artery dilution curves was examined. Right heart and pulmonary artery thermodilution curves were recorded after injection of cool dye into commonly used portals—superior vena caval, right atrial, and inferior vena caval—and the contour compared with the subsequent femoral artery dye dilution curve. With superior vena caval or right atrial injection, the contour and disappearance slopes of the pulmonary artery curve bore an extremely variable relationship to those of the femoral artery curve. In sharp contrast, inferior vena caval injection yielded pulmonary artery curves with disappearance slopes which were highly correlated with the femoral artery slope ( r = .99). With inferior vena caval injection, considerable temporal dispersion and spatial dispersion of indicator is found at the right atrial level. With superior vena caval injection distribution mainly occurred beyond the right atrium and even beyond the pulmonary artery in eight out of ten animal studies. The geometry of the venous system may explain this difference. Inaccuracies in flow calculation from right heart dilution curves in dogs would seem to be minimized by inferior vena caval injection.

A rare and unpredictable complication of firearm and missile injuries is projectile embolism. With only a few cases described in the literature, bullet embolism may become a diagnostic challenge for emergency physicians and military surgeons. Bullet embolization is a rare phenomenon, but the complications can be devastating. Case presentation. A 34‑year‑old man sustained a severe complex abdominoskeletal mine‑blast injury with damage to the hollow organs (duodenum and transverse colon), inferior vena cava and both low extremities. The internal hemorrhage was stopped by phleborrhaphy. The wounds of the duodenum and large intestine were sutured, and gunshot fractures of both anticnemions were stabilized by extrafocal osteosynthesis. The whole‑body CT showed that there was a projectile embolus into the branch of the right mid‑lobe pulmonary artery. No clinical manifestations of pulmonary artery embolism were observed in the patient. After surgery, he developed multiple necrosis and transverse colon perforations that resulted in fecal peritonitis. The suture line leakage that caused the formation of a duodenal fistula and postoperative wound infection were also detected. The complications were managed by multiple reoperations. The attempts of endovascular bullet extraction weren’t undertaken due to severe concomitant injuries, complications and asymptomatic clinical course of pulmonary artery projectile embolism. Open surgery retrieval of the embolus was successfully performed on the 80th day after injury. The patient was discharged from the hospital in good condition on the 168th day after the missile wound. Conclusions. Patients with missile wounds and no exit gunshot perforation should be examined using the whole‑body CT for determining possible migration of a projectile with the blood flow. Patients with asymptomatic pulmonary artery embolism should be managed nonoperatively. In case of symptomatic pulmonary artery projectile embolism, it is reasonable to consider the possibility of open thoracic surgery.
