Problems solved by technology

As a result, the operation is complicated, the operation time, extracorporeal circulation time, systemic circulatory arrest and brain protection time are long, the nervous system and other complications are more, especially postoperative bleeding is sometimes difficult to control, which may cause serious consequences such as death of the patient
A large number of literatures have reported that the above method is used to treat Stanford type A aortic dissection, and the aortic arch replacement is performed using three-branch artificial blood vessels.

Embodiment 1

[0043] Patient ××, male, 48 years old, was admitted to the emergency department with intermittent chest and abdomen distending pain for 6 hours. Clinical diagnosis: acute aortic dissection (Stanford type A), grade 3 hypertension (very high risk group). After preoperative preparation, the artificial vessel with stent was used under general anesthesia and cardiopulmonary bypass for ascending aortic replacement + aortic arch replacement + artificial vessel elephant trunk with stent.

[0044] After general anesthesia, a median sternotomy was made, the right axillary artery + femoral artery and superior and inferior vena cava were intubated, extracorporeal circulation was established and turned around, the aortic arch and innominate artery, left common carotid artery, and left subclavian artery were separated, and cuffed spare. Left ventricular drainage via the right superior pulmonary vein. Lower the temperature, block the ascending aorta, incise the ascending aorta and infuse m...

Embodiment 2

[0046] Patient ××, male, 68 years old, was admitted to the emergency department because of severe pain in the chest and abdomen for 3 days, which aggravated for 1 day. Diagnosis: acute aortic dissection (Stanford type A). After preoperative preparation, the artificial vessel with stent was used under general anesthesia and cardiopulmonary bypass for ascending aortic replacement + aortic arch replacement + artificial vessel elephant trunk with stent.

Abstract

The invention provides an artificial blood vessel with a stent and application of the artificial blood vessel in Stanford A type aortic dissection clinical operations. Treatment can be simplified, andthe operation risk can be reduced. The length of the blood vessel is 15-20 cm, and the blood vessel is made of a dacron artificial blood vessel, wherein the near end is a pure dacron artificial bloodvessel body, the length is 5-10 cm, the length of the far end is 10 cm, and the surface of the far end is a dacron artificial blood vessel body, the interior of the far end is provided with the W-shaped titanium-nickel alloy metal stent with a self-expansion function, and the stent is fixed in a sewn mode; the diameter of the artificial blood vessel with the stent is 24-30 mm. During the operations, artificial blood vessels, with different diameters, provided with stents are selected according to the inner diameters of the aortas of different patients.

Description

technical field [0001] The invention relates to an artificial blood vessel and its application in the clinical operation of Stanford type A aortic dissection. Background technique [0002] Aortic dissection refers to the tearing of the aortic intima under the action of internal and external forces, and blood in the circulation enters between the intima and the media, causing it to peel off, forming aortic dissection, also known as aortic dissection aneurysm. The incidence rate of this disease is about 50-100 cases per 100,000 population per year, and the onset is usually acute. 65%-75% of patients die within 2 weeks from cardiovascular complications such as dissection rupture, cardiac tamponade, and arrhythmia. The incidence rate of men is higher than that of women, and the ratio of men to women is 2 to 3:1. More than 80% of patients with aortic dissection have hypertension, and many patients have cystic medial necrosis of aorta. Hypertension is not the cause of cystic medi...
