Retrograde Pulmonary Embolectomy for Acute Pulmonary Embolism: A Simplified Technique

Flexible fibre optic bronchoscopy as angioscope to ascertain completeness of pulmonary embolectomy: surgery for pulmonary embolism-how I do it

Rarely pulmonary embolectomy has also been used as a salvage procedure for acute right ventricle (RV) dysfunction following acute pulmonary embolism (APE). Complete surgical removal of thromboembolus in acute pulmonary thromboembolism is an essential pre-requisite for good outcome. Complete clearance of thromboembolic load from pulmonary arterial tree is difficult to assess intraoperatively. We hereby describe the use of flexible fibre optic bronchoscope (FFB) as angioscope to visualise the pulmonary arterial tree intraoperatively. Angioscopy ascertains the complete clearance up to subsegmental level after thromboembolectomy and aids in the removal of residual thrombus or embolus. Herein, we describe a case series of two patients, where FFB was used as angioscope during surgery for APE.

Surgical Management of Acute and Chronic Pulmonary Embolism

Surgical pulmonary embolectomy and pulmonary thromboendarterectomy are well-established treatment strategies for patients with acute and chronic pulmonary embolism, respectively. For both procedures, techniques and outcomes have evolved considerably over the past decades. Patients with massive and submassive acute pulmonary embolism are at risk for rapid decline owing to right ventricular failure and shock. When thrombus is proximal, embolectomy can rapidly restore cardiac function. Chronic thromboembolic pulmonary hypertension is a more complex disease that requires skilled, careful dissection of the arterial wall, including vascular intima. When successful, surgery leads to clinical cure of the associated pulmonary hypertension, with excellent long-term outcomes.
