概括

左心室切除用于心室高心率和过早心室复合体 (PVCs) 与大脑栓塞的高风险有关. 需要进一步的研究来了解和预防这些移除后的脑病变.

科学领域:

心脏病学
神经学
医学成像

背景情况:

导管切除是一种常见的治疗室内心跳和过早的室内复合体 (PVC).
大脑栓塞是已知的心房移除的风险,但在心室移除中没有得到充分研究.
了解腹腔切除时的栓塞风险对于患者的安全至关重要.

研究的目的:

评估心室动脉冲动和PVC导管切除后脑栓塞的发生率.
为了比较左心室 (LV) 和右心室切除手术之间的栓塞风险.
为了确定脑栓塞的潜在危险因素.

主要方法:

连续接受了18名心室切除术的患者.
患者被分为左心室 (LV) 切除组和右心室切除组.
在手术前和手术后使用脑磁力共振来检测栓塞性心脏病发作.

主要成果:

在接受LV切除的患者中,有58%患有脑栓塞 (共16例).
在接受右心室切除的患者中没有观察到脑栓塞 (P=0. 04).
63% 的逆行性LV患者出现了新的脑病变.

结论:

常规的左心室切除手术与新的脑栓塞的高发病率有关.
这些发现强调需要进一步研究这些病变的长期影响和预防策略.
与左心室切除相比,右心室切除的脑栓塞风险显著降低.

Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care

Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...

Pulmonary Embolism I: Introduction

Pulmonary Embolism I: Introduction

Pulmonary embolism (PE) occurs when a thrombus, fat or air embolus, amniotic fluid, or tumor tissue blocks one or more pulmonary arteries. These blockages originate in the venous system or the right side of the heart.EtiologyPE primarily arises from deep vein thrombosis (DVT) and other hypercoagulable states, such as inherited thrombophilias. Additional etiological factors include venous stasis, commonly seen in obesity, and endothelial injury from surgery and trauma. Less common causes include...
