Particularly, the present embodiment can according to the difference of Aortic Dissection, and the windowing stent designing different therapeutic schemes and different size carries out intracavitary therapy, mainly comprises following several situation:
The first situation: the dissection of aorta of the first patient, though cut distance left subclavian artery has certain distance, but left subclavian artery opening is positioned at descending aorta initial part, angulation is bad, if at left subclavian artery trailing edge releasing bracket, the bare bracket part of support head end may be caused to support in arteria carotis communis, cause new interlayer to occur.Therefore, need anchorage zone to move forward.But left subclavian artery and left common carotid artery are apart from very short, therapeutic strategy how is selected to be the key for the treatment of.
Particularly, first the Method of printing utilizing the present embodiment to provide prints the 3D printer model of first dissection of aorta of the first patient, and utilize this model to contrast to determine the locus of left common carotid artery and left subclavian artery, angle and circumferential size, and break location makes windowing stent.Wherein, the 3D printer model of first artery dissection of the first patient as shown in Figure 3.
Secondly, according to the in-vitro simulated releasing bracket of 3D printer model of dissection of aorta, following three kinds of schemes are had:
The first scheme, concordant left subclavian artery releasing bracket; But this scheme support angle is bad, therefore gets rid of.
First scheme, left subclavian artery is windowed, releasing bracket; But this scheme left subclavian artery is adjacent with left common carotid artery, the bad location of support is fixed, and therefore gets rid of.
The third scheme, left common carotid artery+left subclavian artery is windowed; Because of this scheme, can to retain these two openings in blood vessels unobstructed, and the cut of closed dissection of aorta, reaches the effect of individualized treatment;
The second situation: the dissection of aorta of the second patient, high-order cut, involves left subclavian artery, contiguous left common carotid artery, the second patient is congenital polycystic kidney, polycystic liver, preoperative hepatic and kidney function obstacle, routine operation cannot be tolerated, unique processing scheme: intracavitary therapy.
Particularly, first the Method of printing utilizing the present embodiment to provide prints the 3D printer model of second dissection of aorta of the second patient, and utilize this model to contrast to determine the locus of left common carotid artery and left subclavian artery, angle and circumferential size, and break location makes windowing stent.Wherein, the 3D printer model of second artery dissection of the second patient as shown in Figure 4.
Secondly, according to the in-vitro simulated releasing bracket of 3D printer model of dissection of aorta, following three kinds of schemes are had:
The first scheme, concordant left subclavian artery releasing bracket; This scheme cannot be closed because of high-order cut, therefore gets rid of.
First scheme, left subclavian artery is windowed, releasing bracket; This scheme cannot be closed because of high-order cut equally, therefore gets rid of.
The third scheme, left neck artery is windowed, releasing bracket; This scheme can close Lacuna of Aortic Dissection, is therefore preferred version.
Finally, window at left neck artery according to the third scheme, releasing bracket, retains its blood flow unobstructed, closes Lacuna of Aortic Dissection simultaneously, reaches the effect of individualized treatment.
The third situation: the 1 type dissection of aorta that the 3rd patient's aorta ascendens is involved, treatment in the past needs to do conventional thoracotomy cardiopulmonary bypass surgery, and wound is large, operative results difficulty.But the Lacuna of Aortic Dissection of this case is at descending aorta, is actually after breaking from descending aorta and tears toward aorta ascendens.More convenient clear and definite pathology details is printed by 3D.
Particularly, the Method of printing first utilizing the present embodiment to provide prints the 3D printer model of the 3rd dissection of aorta of the 3rd patient.Wherein, the 3D printer model of the 3rd artery dissection of the 3rd patient as shown in Figure 5.
Secondly, according to 3D printer model from multi-angle observation, aorta ascendens inner membrance is complete, without cut.Be actually descending aorta cut against tearing aorta ascendens, selecting minimally-invasive treatment in chamber according to this situation is preferred plan.
Finally, endovascular stent-grafts exclusion is carried out to the 3rd patient, close cut, aorta ascendens false chamber blood flow machine, absorption.
Method of printing provided by the invention and printing equipment, view data can be strengthened according to the CT at patient clinical sustainer position, print the 3D printer model of described dissection of aorta, during so that intracavitary therapy can be carried out to Aortic Dissection, this model determination Aortic Dissection can be utilized intuitively, the distribution of arch of aorta top set, and utilize this model to contrast the locus determining left common carotid artery and left subclavian artery, angle and circumferential size, and break location, thus precisely make windowing stent, again by this stenter to implant Ink vessel transfusing, ensure the effect of intracavitary therapy.
