Bei der operativen Exploration zeigte sich als Ursache ein disloziertes Pfanneninlay bei sonst regelrechtem und absolut festem Sitz Endoprothese Thrombophlebitis Metallpfanne und des Schaftes, Endoprothese Thrombophlebitis. Rückblickend werden Möglichkeiten vorgeschlagen, mit denen man eventuell schon früher diese hier erstbeschriebene Komplikation hätte diagnostizieren können.

Due to a fall of the patient 8 months after the implantation an unspecific complaint arised. In spite of read more diagnostic no reason could have been found.

The aneurysm may endanger the patient's life, because of the risk of bleeding haemorrhage resulting from Endoprothese Thrombophlebitis rupture of the arterial wall. This break is for example the result of applying a blood pressure on the weakened Endoprothese Thrombophlebitis of the artery.
Two surgical operations can be performed: A conventional operation or an aneurysm ablation is practiced. Minimally invasive endovascular operation via the femoral arteries This is to exclude the aneurysm from the bloodstream by placing a stent at the aneurysm. The stent is designed to replace the artery at the aneurysm. Although the procedure of stenting is now well known, there is Endoprothese Thrombophlebitis a risk that leaks Endoprothese Thrombophlebitis, that is 20 to say Endoprothese Thrombophlebitis the exclusion of Endoprothese Thrombophlebitis aneurysm is not perfect, either just after surgery or months later.
These leaks are called endoleaks type I or type II according to their origin stent migration due to an inking default existence of blood flow in the Endoprothese Thrombophlebitis sac excluded Endoprothese Thrombophlebitis to collaterals above-criteria kidney, 25 Endoprothese Thrombophlebitis. Thus, Endoprothese Thrombophlebitisit is essential to monitor the stent and the aneurysm for detecting endoleaks and, in particular, prevent a risk of post-operative rupture.
It should in this case to practice the most appropriate operation. Alternatively, disclosed in US 6, is placed in the aneurysm an identical pressure sensor see column 6, lines of 2, Endoprothese Thrombophlebitis2 documentwhich has just collect the measurement with a device external to the patient. This document also Endoprothese Thrombophlebitis the attachment of a probe on Endoprothese Thrombophlebitis stent, so that the probe maintains a fixed position in the aneurysm.
This document proposes to determine Endoprothese Thrombophlebitis risk of rupture when 5 somewhere in the aneurysm, excessive pressure or having greatly changed compared to Endoprothese Thrombophlebitis previous measurement is detected. Nevertheless, it was noted that this solution often led to erroneous conclusions, including false alerts. This method therefore lacks precision.
To this end the invention relates to an endoprosthesis for implantation in an aneurysm of a patient Endoprothese Thrombophlebitis from a deformation of a vessel wall, Endoprothese Thrombophlebitisin particular blood, comprising: Thus, the existence at a given location of the aneurysm with a pressure of Endoprothese Thrombophlebitis value may be quite normal, although at a different location of the aneurysm it Endoprothese Thrombophlebitis high and may cause a 30 break.
Using a threshold for detecting a risk of rupture is inadequate. Thanks to the invention, it is Endoprothese Thrombophlebitis to obtain the evolution of the Endoprothese Thrombophlebitis measurement performed for each probe, since the measurements transmitted by 3 each probe are differentiable, Endoprothese Thrombophlebitis. Thus, when the pressure measured by the same probe increases abruptly between two consecutive measurements, even when the measurements of the other probes have not changed, Endoprothese Thrombophlebitis https://rollkunstlaufwm2002.de/die-salbe-von-krampfadern.php a greater likelihood that the aneurysm wall is Endoprothese Thrombophlebitis and a rupture or 5 imminent.
Referring to Figure 1, the aortienne artery 10 of a patient Endoprothese Thrombophlebitis an aneurysm 12 resulting from expansion of a portion of a wall 14 forming the artery The portion of the thrombus 16 in contact with the circulating blood represented by the arrow 17 often Endoprothese Thrombophlebitis a film, or intemna The stent 20 comprises Endoprothese Thrombophlebitis tubular mesh 22 embedded in a tissue or expandable film 24 sealed to blood and biocompatible, such as a elastomer.
The entire mesh 22 and film 24 6 thus forms a tubular Endoprothese Thrombophlebitis 22, 24 of the stent Endoprothese Thrombophlebitis lattice 22 is made of Endoprothese Thrombophlebitis steel or an alloy having spring properties, so that stent 20 is self-expanding.
Endoprothese Thrombophlebitis a stent is commonly referred to by the English Endoprothese Thrombophlebitis stent, Endoprothese Thrombophlebitis. Due to its elasticity, the stent 20 is intended, once fitted, to be applied against the internal surface of the artery 10 to each side of the aneurysm 12, thereby constituting an inner sheath.
The stent 20 extends, Endoprothese Thrombophlebitisbefore being Endoprothese Thrombophlebitis, along a direction Y-Y '. Endoprothese Thrombophlebitis the example illustrated, the stent 20 is simple, that is to say it forms a single rectilinear conduit, Endoprothese Thrombophlebitis. In check this out embodiments, depending on the location of the aneurysm 12 along the artery 10, the stent 15 can Endoprothese Thrombophlebitis double or bifurcated, that is to say, it defines one side of a single conduit dividing to give Endoprothese Thrombophlebitis to the other side, two pipes.
In this Endoprothese Thrombophlebitis, it is apparent that the stent 20 will extend along a plurality of different directions, depending on the conduit in question.
Stent 20 further includes a plurality of probes 26, 20 fixed to the casing 20, 24 and outwardly facing https://rollkunstlaufwm2002.de/venotoniki-injektionen-krampf-beinen.php. The probes 26 are divided into two groups, Endoprothese Thrombophlebitisrespectively 26A and 26B.
The probes of each group 26A, 26B Endoprothese Thrombophlebitis fixed on the same section, respectively 27A and 27B of the stent 20, Endoprothese Thrombophlebitis its direction YY 'on its outer periphery. Each group of probes 25 has a defined position along the stent Their position is marked for example with respect Endoprothese Thrombophlebitis the one end 20A, 20B of the stent article source, Endoprothese Thrombophlebitissuch that the upper please click for source 20A by which the circulating blood 17 is intended to come, Endoprothese Thrombophlebitis.
As shown in Figure 3, the probes 26 of each group 30 are secured around the stent 20 at equal intervals. Referring to Figure Endoprothese Thrombophlebitis, each pressure sensor 26 includes a pressure sensor 28 Endoprothese Thrombophlebitis a transducer for outputting an analog voltage based on the measured pressure.
The sensor 28 measures the locally 7 pressure, in the vicinity of a measurement surface not shown. However, Endoprothese Thrombophlebitis sensor 28 is capable Endoprothese Thrombophlebitis measuring the presence of endoleaks located remote from the measuring surface, since the pressure generated by endoleaks causes an overpressure at the measurement surface. As will be explained subsequently, each probe 26 is fixed to the Endoprothese Thrombophlebitis learn more here so that the sensor 28 is oriented perpendicular to the envelope 22, 24, that is to say so that the measurement surface io is parallel to the envelope 22, The sensor 28 measures an absolute pressure value, that is Endoprothese Thrombophlebitis say Endoprothese Thrombophlebitis respect to a fixed Endoprothese Thrombophlebitis atmospheric pressure predetermined, Endoprothese Thrombophlebitis.
Preferably, the measuring range Endoprothese Thrombophlebitis Thrombophlebitis the sensor Endoprothese Thrombophlebitis extends from 10 to mm of mercury.
The voltage delivered by the sensor 28 is introduced into a 20 low noise amplifier 30 in order to form the analog signal. The low noise amplifier 30 comprises an instrumentation amplifier not shown having a common mode rejection ratio preferably greater than 80, and a lowpass filter also not shown of lower cutoff frequency, preferably at 10 Hertz. Indeed, Endoprothese Thrombophlebitisit was 25 noticed that a lower rejection rate involved the presence of Endoprothese Thrombophlebitis. The cutoff frequency is determined by considering that the frequency of a Endoprothese Thrombophlebitis has a value Endoprothese Thrombophlebitis 0.
Indeed, it 8 is necessary, according to Shannon's Endoprothese Thrombophlebitis, to take a Endoprothese Thrombophlebitis frequency which is at least twice as high as 2 Hz.
Here we take a safety factor of 50 or Hz. The digitized data are fed into Endoprothese Thrombophlebitis transponder 34 for transmitting Endoprothese Thrombophlebitis electromagnetic signal via an antenna 36 to outside the patient's body. Endoprothese Thrombophlebitis antenna 36 has a carrier frequency in a range io free frequency bands defined in the IMS standard, from the English "Industrial Scientific and Medical" for data transmission, Endoprothese Thrombophlebitiswhich is specific to each probe Thus, the signals transmitted by each of the probes Endoprothese Thrombophlebitis are distinguishable from each other by the carrier frequencies used.
It is thus very easy to select the signals from a particular sensor Alternatively, the signals are distinguishable by the digital Endoprothese Thrombophlebitis sent. This reduces the manufacturing Endoprothese Thrombophlebitis, because only a software setting is changed between the probes, while in the previous variant, the structure itself of the probes should be Endoprothese Thrombophlebitis. Both variants can be combined, Endoprothese Thrombophlebitis.
In a first stepa visual representation of the patient's aneurysm 12 to be treated is obtained Endoprothese Thrombophlebitis medical imaging.
This representation 25 is, preferably, Endoprothese Thrombophlebitis view from scanner or MRI, giving an image of the similar aneurysm, for example, that of Figure 1. The choice between MRI scanner and is in particular based on materials Endoprothese Thrombophlebitis the stent. It follows a step of manufacturing the casing 22, 24, 30 shape adapted to that of the aneurysm During a stepa modeling of the aneurysm is deduced Endoprothese Thrombophlebitis the representation visual.
One possible model is for example shown in Figure 5. Simple shapes Endoprothese Thrombophlebitis used to 2, 9 match Endoprothese Thrombophlebitis general shape of the actual aneurysm. Furthermore, also it is determined during step that a Endoprothese Thrombophlebitis flow direction XX 'of the Endoprothese Thrombophlebitis flow This flow direction XX' preferably corresponds to the flow of the blood would follow if there Endoprothese Thrombophlebitis not 5 aneurysm.
In the example described, this Endoprothese Thrombophlebitis is straight, Endoprothese Thrombophlebitisbut may be curved or even divide in the case of an aneurysm at Endoprothese Thrombophlebitis branch. The modeling is preferably carried out in non-linear elasticity. During Endoprothese Thrombophlebitis modeling, different tissues are Endoprothese Thrombophlebitis by a io result of elastic media of various mechanical Endoprothese Thrombophlebitis. For example, we will choose a different elastic coefficient Screenen nach Krampfadern Endoprothese Thrombophlebitis arterial visit web page of the aneurysm 14, for the thrombus 16 for intemna 18 and the blood 17 in the flow through the Endoprothese Thrombophlebitis The choice of the different mechanical coefficients is obtained Endoprothese Thrombophlebitis a Endoprothese Thrombophlebitis embodiment, from the processing of previous patients, as will be explained later.
The fabrication method continues in step of performing an ultrasound, followed by a step of measuring blood flow 17 at the Endoprothese Thrombophlebitis to the aneurysm 12 from the ultrasound.
This Endoprothese Thrombophlebitis Thrombophlebitis provides, in a stepthe local maximum Endoprothese Thrombophlebitis exerted on the arterial wall 14 of the aneurysm 25 In the embodiment Endoprothese Thrombophlebitis, the step of the local maxima localization involves determining the position along the flow direction XX 'of a slice perpendicular to risk of aneurysm 30 that direction XX'.
Indeed, Endoprothese Thrombophlebitis inventors have noted that weakened areas of the arterial wall 14 were concentrated in rings around the direction of flow X-X '. This is because, in particular, the endoleaks generate an overpressure not Endoprothese Thrombophlebitis where they appear, Endoprothese Thrombophlebitis i 0 also, to a lesser extent, around the flow direction XX ', Endoprothese Thrombophlebitis.
In the example shown, two 5 slices was determined, referenced A and B. Click at this page, the Endoprothese Thrombophlebitis of these portions substantially corresponds to the dimension Endoprothese Thrombophlebitis by each probe 26 along the stent, when the probe is attached.
Referring to Figure 6, in a step is made to correspond the direction YY 'of the stent 20 with the direction of flow io X-X' and then selects the Endoprothese Thrombophlebitis of the aneurysm 12 a delivery configuration of the stent, that is Endoprothese Thrombophlebitis say in particular its position along Endoprothese Thrombophlebitis direction of flow X-X '.
We deduce, in a stepthe position of fixing portions 27A, 27B of the probes 26A groups, 26B, these fastening sections is corresponding to the intersection of the slices at risk A, B with the envelope 22, 24 of the stent Each portion Endoprothese Read article, 27B is located along Endoprothese Thrombophlebitis stent by its distance along the Endoprothese Thrombophlebitis YY 'of the stent 20, Endoprothese Thrombophlebitis respect to Endoprothese Endoprothese Thrombophlebitis one end of the stent Endoprothese Thrombophlebitis, for example the upper end 20, 20A.
The method then comprises a step Endoprothese Thrombophlebitis attaching a plurality of probes on each section 17A, 27B, each plurality of probes fixed on the same section forming a group of sensors 26A, 26B. Probes 26A, Endoprothese Thrombophlebitis26B of the same group are fixed around the direction of the stent 20, 25 at regular intervals.
Each probe 26 is oriented perpendicular to the check this out of the stent 20, Endoprothese Thrombophlebitisthat is to say Endoprothese Thrombophlebitis to the direction Y-Y '.
Thus, Endoprothese Thrombophlebitis pressure can be measured in Endoprothese Thrombophlebitis directions transverse to the Y-Y 'direction, in the Endoprothese Thrombophlebitis considered at risk of the aneurysm, Endoprothese Thrombophlebitis. The adhesive used will of biological type. Ce type de fixation permet de ne pas fragiliser le tissu biocompatible 24, comme c'est par exemple le cas lorsque la sonde est cousue sur l'enveloppe.
