Cardiovascular diseases during pregnancy are rare but account for complications that pose risks to the mother as well as the child. In patients with fixed cardiac output due to stenotic valvular lesion(s), the physiological changes during pregnancy carry high risk of morbidity and mortality.
Our patient was diagnosed with severe mitral and aortic stenosis at her first antenatal visit at 24 weeks of gestation. She was also diagnosed with intrauterine growth restriction and was therefore planned to be operated on at a gestational age of 34 weeks. After careful selection of monitoring and anesthetic regime, the patient was managed without any intraoperative or postoperative complications.
This case reports how the anesthetists, obstetricians, and cardiac surgeons devised a well-designed plan to operate on a patient with a relatively rare disease manifestation. Our patient had coexisting severe stenotic lesions of both mitral and aortic valves and posed a clinical dilemma regarding the choice of anesthesia and perioperative management. Regardless of the anesthetic technique, goals for a patient with the combined valvular disease include maintenance of adequate preload, systemic vascular resistance, cardiac contractility, sinus rhythm and avoidance of tachycardia, bradycardia, aortocaval compression, and anesthetic or surgery-induced hemodynamic changes.
The course of management would give clinicians an idea of how to manage a patient with combined stenotic valvular lesions for cesarean section, ensuring a smooth course and a safe postoperative period.
孕期心血管疾病较为罕见,但会引发对母亲和胎儿都有风险的并发症。对于因瓣膜狭窄病变导致心输出量固定的患者,孕期的生理变化会带来较高的发病和死亡风险。
我们的患者在妊娠24周首次产前检查时被诊断为重度二尖瓣和主动脉瓣狭窄。她还被诊断出胎儿宫内生长受限,因此计划在孕34周时进行手术。在仔细选择监测和麻醉方案后,患者在术中及术后均未出现任何并发症。
本病例报告了麻醉医生、产科医生和心脏外科医生如何为一名患有相对罕见疾病表现的患者精心设计手术方案。我们的患者同时存在二尖瓣和主动脉瓣的严重狭窄病变,在麻醉选择和围手术期管理方面构成了临床难题。无论采用何种麻醉技术,对于合并瓣膜疾病的患者,目标包括维持足够的前负荷、体循环血管阻力、心脏收缩力、窦性心律,避免心动过速、心动过缓、主动脉腔静脉压迫以及麻醉或手术引起的血流动力学变化。
该管理过程将让临床医生了解如何为合并狭窄瓣膜病变的患者进行剖宫产手术管理,确保手术过程顺利和术后安全。
