We report our techniques on conducting a closed-circuit femoral-femoral bypass during descending aortic surgery by which collected blood can be easily returned into the right atrium. The main circuit was composed of a centrifugal pump, an artificial membrane lung, and a filter. A reservoir with a roller pump was connected to the main circuit via a filter. Extracorporeal circulation was establis...

A 77-year-old man was admitted with multiple co-morbidities including cerebral infarction, postoperative ossification of the cervical posterior longitudinal ligament, sick sinus syndrome with a cardiac pacemaker inserted from the right subclavian vein, and panperitonitis due to a complicated gastrostomy catheter exchange. The patient developed a critical and rare complication of central venous ...

BACKGROUND Venoarterial-venous extracorporeal membrane oxygenation (VAV ECMO) configuration is a combined procedure of extracorporeal membrane oxygenation (ECMO). The proportion of cardiac and respiratory support can be controlled by adjusting arterial and venous return. Therefore, VAV ECMO can be applicable as a bridging therapy in the transition from venoarterial (VA) to venovenous (VV) ECMO....

May–Thurner syndrome (or iliocaval compression syndrome) is defined as a compression of the iliac vein that results in decreased flow in the vein and the left lower extremity due to a vascular malformation. It may result in left leg edema, pain, iliofemoral DVT, and postthrombotic syndrome. Compression of the left common iliac vein by the right common iliac artery against the underlying fifth l...

Extracorporeal membrane oxygenation (ECMO) is increasingly being used in adults following failure to wean from cardiopulmonary bypass, after cardiac surgery or in cases of severe respiratory failure. Knowledge of the different types of ECMO circuits, expected locations of cannulas and imaging appearance of complications is essential for accurate imaging interpretation and diagnosis. Commonly en...

BACKGROUND When access cannot be achieved using a native arteriovenous fistula or a synthetic prosthetic graft, central venous catheters are usually placed. This mode of access is short-lived, prone to infection, stenosis and thrombosis of central veins. To overcome access problems, we developed a new native vascular access ('femoral vein access') and devices. We report here on our experience w...

The course and ramification of the vessels of the lower limbs have long received attention from anatomists and surgeons. During educational dissection with undergraduate students of the Department of Anatomy of the NRI Medical College we observed in a male cadaver of about 55 years the rare variation of the profunda femoris artery originating from the medial side of the femoral artery and cours...
