許多人, 甚至有些醫師, 對漏斗胸都不甚了解, 往往誤認為漏斗胸只是單純外觀問題, 其實只要仔細評估, 多會有心肺壓迫的情形, 主要多是右心的三尖瓣及肺動脈瓣逆流及二尖瓣脫垂等等.

這一篇論文是報告一15歲男性漏斗胸病人在俯臥姿勢接受脊柱側曲手術時, 發生嚴重之低血壓, 經食道內心臟超音波檢查發現右心室(直接在凹陷的胸骨後方的心臟部分)受到壓迫. 右心室最高及平均血流入梯壓分別為7及4毫米汞柱. 但平躺時心受凹陷胸骨壓迫的情況即復原.


謹建議, 嚴重漏斗胸患者要儘量避免俯臥姿勢

INTRODUCTION: Pectus excavatum is commonly viewed as a benign condition. Associated alterations in hemodynamics are rare. We present an unusual case of right ventricular inflow obstruction and hemodynamic compromise as a consequence of pectus excavatum encountered during surgical intervention.
CASE: a 15-year-old male with pectus excavatum and thoracolumbar scoliosis developed severe hypotension after induction of general anesthesia and placement in the prone position for elective spinal fusion. A transesophageal echocardiogram revealed anterior compression of the right heart by the sternum with peak and mean right ventricular inflow gradients of 7 and 4 mm Hg, respectively. The gradient resolved with supine positioning and was reproduced with direct compression of the sternum.
CONCLUSIONS: Although pectus excavatum is generally a benign condition, the cardiologist should be aware of the potential for serious hemodynamic compromise related to positioning in these patients.
