Experts discuss the effectiveness of this system in the rapid removal of emboli and thrombi from vessels of the peripheral vasculature. Benenati has disclosed that he is a consultant to Penumbra, Inc, Lungenembolie Code. Lungenembolie Code endovascular options for lower extremity and visceral arterial thromboembolism face the challenges of limited trackability, vessel injury, and incomplete revascularization.
At the forefront of advances in catheter materials and technology, Lungenembolie Code, Penumbra, Inc. The Indigo System is designed to address the limitations of conventional technology, Lungenembolie Code, bringing greater Lungenembolie Code and the power of large-bore catheters and the Indigo pump to the peripheral vasculature.
Lower extremity arterial thromboembolism or vessel thrombosis are major concerns, as they can block blood flow to the limbs. Atherectomy is associated with a substantial rate of distal embolization. Although thrombolysis and surgical embolectomy are established therapies for these events, percutaneous devices are now available for the mechanical extraction of thrombus and distal emboli.
These devices, such as the Penumbra Indigo System, are playing a larger role in the treatment of acute limb ischemia and in the rapid removal of atheroemboli when they occur Lungenembolie Code procedures. The Penumbra System used vacuum aspiration as its primary mechanism of action. A flexible, large-bore catheter was delivered to the site of occlusion, and aspiration was directly applied to the lesion itself, Lungenembolie Code.
The Separator allowed continuous thrombectomy under constant aspiration supplied by an external vacuum pump. Recognizing the utility of this device, operators that were familiar with the Penumbra System for stroke care started using it in the peripheral vasculature for acute thrombotic and embolic events. This enabled physicians to treat lesions that were previously inaccessible with conventional technology.
InPenumbra launched the Indigo System specifically for this application, Lungenembolie Code below-the-knee mechanical thrombectomy, Lungenembolie Code.
The Indigo System enables the removal of emboli and thrombi from vessels of the peripheral arterial system. Unlike thrombolysis, which often requires prolonged infusion times, Lungenembolie Code, Indigo is able to provide rapid restoration of flow to thrombosed vessels.
It can also be used for revascularization when Lungenembolie Code therapy and surgery are contraindicated, Lungenembolie Code. This 6 F—compatible percutaneous system is available in 6-F and 4-F catheter options with to cm catheter lengths. Indigo has the largest extraction lumen designed for vessels below the knee, with smaller and longer catheter options for hard-to-reach distal extremities.
The following cases demonstrate rapid revascularization times Richard R. Saxon has disclosed that he is a consultant to Penumbra, Inc. When treating patients with acute or subacute arterial occlusions, there are times when thrombolytics are contraindicated or fail to lyse the thrombus.
In such cases, Lungenembolie Code, the Indigo System has been a very effective tool, allowing us to reopen occluded vessels by successfully aspirating thromboemboli in a variety of difficult circumstances.
An year-old woman with a history of atrial fibrillation developed class IIa acute limb ischemia. Initial angiography showed a popliteal artery occlusion and poor distal runoff, with thrombus in the proximal peroneal artery. It was elected to treat the patient with thrombolytic therapy, and a tissue plasminogen activator infusion was initiated through a multisidehole catheter placed across the occlusion.
Angiography was again performed after 24 hours of thrombolytic therapy. The popliteal artery was widely patent, but the distal vasculature was still poor, with diseased one-vessel peroneal runoff, Lungenembolie Code.
It was elected to continue the lytics for an additional 12 to 24 hours in the hopes that the runoff would improve.
Unfortunately, after 40 hours of thrombolytics Figure 1the popliteal artery had rethrombosed for reasons that were unclear.
Due to concerns about the risks associated with Lungenembolie Code thrombolytics, we attempted a mechanical approach. Figure 2 shows the larger 6-F Indigo catheter and Separator in place as Lungenembolie Code system is slowly passed through the thrombus. After reopening the popliteal artery, the Lungenembolie Code, 4-F Indigo catheter was used coaxially with the Separator to open the peroneal artery, Lungenembolie Code.
After mechanical thrombectomy, Lungenembolie Code, percutaneous transluminal popliteal angioplasty was performed to treat a moderate residual stenosis. The final angiogram Figure 3 showed that all Varizen Dorn the thrombus was successfully removed, and diseased one-vessel runoff was preserved, with no distal embolization during the procedure.
Today, there is an ever-growing array of endovascular techniques that can be used to treat occlusive disease causing claudication or critical limb ischemia. In order to perform more aggressive endovascular procedures safely, it is imperative to be completely equipped with the right set of tools to deal with any complications that may arise.
In this case report, Indigo enabled the rapid removal of debris and restored flow following a reentry procedure. A year-old woman with chronic severe lower extremity claudication presented for endovascular treatment after being managed medically for Lungenembolie Code years.
Initial angiography demonstrated a densely calcified superficial femoral artery SFA with a chronic total occlusion in its mid-portion Figure 1. Note the normal three-vessel runoff with a widely patent distal posterior tibial artery the dominant runoff vessel into the foot. The lesion proved difficult to cross, necessitating a subintimal approach using a Lungenembolie Code device.
After percutaneous transluminal angioplasty of the SFA, the severe residual stenosis was successfully treated by endograft placement Figure 2 A. However, runoff postintervention showed embolic occlusion of the distal posterior tibial artery at the ankle Figure 2 B. The 4-F Indigo catheter was used from a contralateral femoral approach Figure 3 Aand follow-up angiography after Figure 3 B. Schönholz has disclosed that he is a speaker for Penumbra, Lungenembolie Code, Inc.
Adams stated that he has no financial interests related to this article. With the rapidly changing landscape of peripheral arterial disease, it has now become possible to treat patients, who in years past would have required open surgery, with modern endovascular techniques such as mechanical thrombectomy with the Indigo System.
The patient had a juxtarenal abdominal aortic aneurysm and was not a candidate for open surgery. The snorkel technique was used to treat this patient, Lungenembolie Code.
A stent graft was placed, along with two self-expanding covered stents in both renal Lungenembolie Code, to maintain blood flow. The postprocedure angiogram showed a faint blush in the abdominal aortic aneurysm sac. These usually tend to resolve, and therefore, no further intervention was performed. The follow-up CT angiogram CTA at 1 month showed a persistent endoleak through the gutters bilaterally, with outflow through a patent lumbar artery on the right side.
To treat the persistent endoleak, embolization with microcoils was performed from a femoral approach. A follow-up CTA showed resolution of the endoleak and reduction in the size of the aneurysm sac Figure 1. Four months later, the patient presented reporting 48 hours of anuria. The CTA showed bilateral renal snorkel occlusion with an already atrophic left kidney, Lungenembolie Code. Angiography confirmed that the right renal artery was also occluded and possibly causing the anuria Figure 2.
The 6-F Indigo catheter was delivered to the right renal artery through a 6-F sheath. The catheter was then connected to the Indigo pump and cleared the thrombus Lungenembolie Code minutes.
The thrombus can be seen in the canister in Figure 3, Lungenembolie Code. This was then followed by the placement of a balloon-expandable stent to help ensure long-term patency of the right renal artery. The patient recovered renal function soon after the right renal artery was revascularized Figure 4.
The treatment of occluded viscerals with conventional techniques is often time-consuming with limited success, Lungenembolie Code. Now, with the Indigo System, we have expanded Creme von Krampfadern und Besenreiser endovascular visceral thrombectomy options while decreasing procedure time. We are also now able to actually visualize the clot collected in the canister Figure 3.
Angioplasty, stenting, and drug-eluting technologies are all continually being improved to provide adequate endovascular treatment options and prevent or prolong the duration before open surgery is required. Although drug-coated balloons and drug-eluting stents show promise, dealing with ISR Lungenembolie Code the current patient population warrants the need for good endovascular techniques.
The Indigo System is proving to be a great option. The patient first presented in with bilateral claudication and was able to walk approximately 50 yards.
Angiography revealed a total occlusion of the right common and external iliac arteries, Lungenembolie Code, as well as a chronically occluded Lungenembolie Code SFA, Lungenembolie Code. Percutaneous intervention was unsuccessful, and so a left common femoral-to-right common femoral bypass was performed to perfuse the right lower extremity.
At approximately 3 months postprocedure, there was resolution of right lower extremity claudication. However, the patient was now limited by left lower extremity claudication. The patient was therefore taken back to the catheterization lab, and antegrade access was achieved focusing on the left SFA occlusion. Angioplasty was attempted with a cutting balloon throughout the stent but failed to reconstitute flow Figure 1 A. The CAT5 was connected to the Indigo pump, which supplies continuous vacuum and allows for hands-free aspiration.
Within minutes, the thrombus was completely evacuated from Lungenembolie Code stent Figure 1 B and C. It also showed the location of the culprit restenosis, which was then treated by placing two drug-eluting stents in an attempt to prevent future recurrence Figure 1 D. Thrombus is a common component in lower extremity peripheral arterial disease, warranting the use of thrombectomy.
In this case, the ability to connect the CAT5 device to the Indigo pump for continuous suction, Lungenembolie Code clogging the tip of the device, allowed for the safe and rapid removal of mural thrombus that had accumulated over the entire stent segment, without the need for wire exchanges.
In treating these advanced stages of disease, the need for sophisticated interventional tools is heightened. The patient presented with acute thrombosis of a 6-mm covered stent in the above-the-knee popliteal artery that had been placed as a secondary intervention within an initially deployed bare stent.
A diagnostic angiogram showed an occluded segment Figure 1with normal flow above and below the stent. The larger 6-F Indigo catheter was used to successfully treat the residual thrombus. A 6- X mm cutting balloon was then used to treat the stenosed segment; however, this resulted in new thrombus in the tibioperoneal trunk, Lungenembolie Code.
An intra-arterial tissue plasminogen activator bolus was attempted, but failed to remove the thrombus. The same 6-F Indigo catheter was again used to clear the tibioperoneal trunk, with a very successful result Figure 2. The Indigo System has now become the standard thrombectomy tool in our peripheral practice and has significantly reduced the need for overnight lytics in the intensive care unit.
Golzar stated that he has no financial interests related to this article. Lower extremity arterial thromboembolism is a significant problem for the interventional community. With increasing use of endovascular techniques, Lungenembolie Code, the risk of embolization during procedures has also greatly increased.
Current practice has evolved to utilizing distal protection devices during power-pulse mechanical thrombectomy to help capture debris and thrombus that may shower distally and thus avoid complications, Lungenembolie Code. After successful revascularization, Lungenembolie Code, the previously placed filter was removed, and the distal runoff looked poor Figure 1.
