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.

A 64-year-old man was admitted for gross hematuria. Preoperative study revealed right renal cell carcinoma with inferior vena cava(IVC) tumor thrombus. Right radical nephrectomy was performed, and deep hypothermic circulatory arrest(DHCA) with retrograde cerebral perfusion(RCP) was used for extraction of tumor thrombus in the IVC. The thrombus originated from the right kidney, which extended the orifice of the gonadal vein in the left renal vein laterally, the hepatic vein superiorly, and 3cm below the right renal vein inferiorly. The thrombus was removed completely without caval wall injury under DHCA with RCP, and the postoperative course was uneventful. He received immunotherapy with interferon, and followed up without any surgical problem.
