Cardiac rupture after blunt trauma is very rare and caval injury is even rarer. However, cardiac rupture after blunt trauma is associated with very high mortality and can occur without a high speed collision or severe thoracic injury. Symptoms are not expressed in all patients in the early stage, so the condition is easily overlooked if patients have an associated injury, minimal thoracic injury or relatively stable vital signs. We report the successful management of two cases of vena caval injury after blunt trauma with slight thoracic injury.

Because of the. rise in the incidence of high speed automobile accident and various gun shot wound, complicated vascular injuries are becoming more frequent. Inferior vena caval injury seems to be also in high incidence, but reports in the literature were rare. because of potentially lethal. Recently we have experienced a case of inferior vena caval injury due to stab wound on the posterior aspect of the right abdomen. This was successfully treated with inferior caval ligation on the both, proximal and distal of the injured infrarenal vena cava.

AMP-activated protein kinase (AMPK) protects various tissues and cells from ischemic insults and is activated by many stimuli including mechanical stretch. Therefore, this study investigated if the activation of AMPK is involved in stretch-induced cardioprotection (SIC). Intraventricular balloon and aorto-caval shunt (ACS) were used to stretch rat hearts ex vivo and in vivo, respectively. Stretch preconditioning reduced myocardial infarct induced by ischemia-reperfusion (I/R) and improved post-ischemic functional recovery. Phosphorylation of AMPK and its downstream substrate, acetyl-CoA carboxylase (ACC) were increased by mechanical stretch and ACC phosphorylation was completely blocked by the AMPK inhibitor, Compound C. AMPK activator (AICAR) mimicked SIC. Gadolinium, a blocker of stretch-activated ion channels (SACs), inhibited the stretch-induced phosphorylation of AMPK and ACC, whereas diltiazem, a specific L-type calcium channel blocker, did not affect AMPK activation. Furthermore, SIC was abrogated by Compound C and gadolinium. The in vivo stretch induced by ACS increased AMPK activation and reduced myocardial infarct. These findings indicate that stretch preconditioning can induce the cardioprotection against I/R injury, and activation of AMPK plays an important role in SIC, which might be mediated by SACs.

64세 남자가 혈뇨를 주소로 입원하여 하대정맥으로 종양 혈전이 파급된 우측 신세포암으로 진단받았다. 우신 적출술 시행 후 역행성 뇌관류하면서 심도 저체온 순환정지 하에 하대정맥 혈전 제거술을 시행하였다. 종양 혈전은 우 신에서 기원하여 하대정맥으로 자라면서 좌 신정맥의 생식선정맥 유입구까지, 위로는 간정맥 유입부까지, 아래로는 신정맥 하방 3cm까지 파급되어 있었다. 심도 저체온 순환 정지 하에서 하대정맥 손상 없이 혈전을 완전히 제거하였고 술 후 경과는 순조로웠다. 술 후 인터페론 면역 치료를 받았고 특별한 문제없이 추적관찰 중이다.
