Talking points for aortic coarctation intervention

  Endoluminal treatment of aortic coarctation is a means of surgical intervention for aortic coarctation. Since it is a combination of open surgery and intervention, there are some special points in addition to the various complications of conventional surgery: 1. Intraoperative sealing of the left subclavian artery: Most aortic type III coarctation ruptures are located within 1-2 cm of the descending aortic arch
The left subclavian artery needs to be partially or completely occluded. The blockage usually does not cause ischemia of the left upper limb, but preoperative imaging should be performed to understand the bilateral vertebral arteries and try not to completely block the left subclavian artery for patients with left dominant vertebral artery.  2.
Intraoperative stent displacement: Due to the morphology of the patient’s arterial arch, the location of the true and false lumen, the size of the false lumen and the rigidity of the stent delivery system itself are objective factors causing stent displacement, while the operator’s experience is a subjective factor causing some stent displacement, the consequences of displacement may be endoleaks or blockage of the left common carotid artery, requiring additional cuff or measures to lower the stent and drag it back to the appropriate position.  3. Intraoperative or postoperative rupture: will result in patient death with an incidence of about 1%.  4.
Postoperative paraplegia: the incidence of transient mild paralysis is 1.9%, the incidence of paraplegia is 0.6%, and there is no report of permanent paralysis in China. Once it occurs, immediate dehydration, hormone administration, maintaining systolic blood pressure above 140 mmHg, and cerebrospinal fluid extraction are also possible.  5. postoperative febrile reaction: some patients may have fever, the temperature is mostly below 38.5℃, but some patients have reached 41℃, most of the blood picture is not high, the fever can last 1-4 weeks, individual longer.  6. Contrast agent toxic side effects and contrast nephropathy.
