A challenging case of dislodged stent retrieval with the use of Goose neck snare kit

We report a case of successful transfemoral retrieval of a dislodged and mechanically distorted coronary stent from the right coronary artery in a middle age woman. The distorted stent was recovered via upsizing of her femoral arterial sheath and the use of a microsnare. The procedure was further complicated by significant right common femoral artery dissection, which was treated with percutaneous transluminal angioplasty from her contralateral femoral artery. The patient recovered well and was discharged the following day. © 2009 Wiley‐Liss, Inc.     

Successful retrieval of a coronary stent dislodged in the brachial artery by means of improvised snare and guiding catheter

This is a case report regarding the retrieval, by means of an improvised snare and guiding catheter, of a stent dislodged in the brachial artery during a transradial coronary intervention. A full-length guiding catheter could not be used to approach the lost stent, which was a mere 30 to 35 cm away from the sheath insertion site at the radial artery, and a commercial snare was not available at the time. Thus, we had to improvise a shortened guiding catheter and a snare, which was formed by folding an angioplasty Whisper guide wire (Abbott Laboratories, Abbott Park, IL) and was used successfully to snare the stent and retrieve it.     

Concurrent use of pigtail and loop snare catheters for percutaneous retrieval of dislodged central venous port catheter

The purpose of this study was to report our experience of percutaneous retrieval of dislodged port catheters with concurrent use of pigtail and loop snare catheters. During a 5-year period at our institute (June 2005 to July 2010), a total of 23 dislodged port catheters were retrieved. The interval between port catheter implantation and dislodged catheter retrieval ranged from 43 days to 1,414 days (mean 586.7 days). The time of delayed retrieval ranged from 1 day to 45 days (mean 4.6 days). All dislodged catheters were retrieved with the concurrent use of pigtail and loop snare catheters via femoral venous route. The prevalence of port catheter dislodgement at our institute was 3.4%. All dislodged port catheters were removed successfully with pigtail and loop snare catheters together. No procedure-related complications were encountered, except for transient arrhythmia in two patients, which required no medication. In conclusion, the concurrent use of pigtail and loop snare catheters is a feasible and easy way for percutaneous retrieval of a dislodged central venous port catheter.     

Surgical retrieval of dislodged stent during transradial coronary intervention

Coronary stent dislodgment is a rare but serious complication during percutaneous coronary intervention. During transradial coronary intervention, retrieval of a dislodged and deformed stent into the guiding catheter is difficult or impossible, since a small 6 Fr guiding catheter and sheath system is commonly used. I describe a new method to retrieve a dislodged and damaged stent during transradial coronary intervention. When a dislodged and unexpanded stent is not pulled back completely into the guiding catheter, the damaged stent and guiding catheter can be withdrawn together into the radial artery and retrieved successfully by radial artery cutdown and repair method.     

Transradial retrieval of a dislodged stent from the left main coronary artery

We report a case of successful transradial retrieval of a dislodged and mechanically distorted coronary artery stent from the left main stem in an elderly male. Transradial percutaneous coronary intervention was undertaken to reconstruct a lesion in the left circumflex artery complicated by stent dislodgement. A microsnare was used to successfully retrieve the stent.     

Accidental retrieval of a fully deployed stent: A case report

We describe a case of accidental retrieval of a fully deployed stent in ostial left anterior descending (LAD) artery. This occurred while attempting stent delivery in obtuse marginal (OM) artery due to entrapment of a wire which inadvertently had passed through the struts of ostial LAD stent. The proposed mechanism and recommendations to avoid this rare complication are discussed. © 2015 Wiley Periodicals, Inc.     

Successful retrieval of a lost coronary stent from the descending aorta using a loop basket intravascular retriever set

Delivery of a balloon-expandable stent was complicated by a systemic embolisation. The radio-opaque stent was lost in the descending aorta, but then removed by using a loop basket intravascular retriever set without any peripheral arterial complication. Cathet. Cardiovasc.

IVUS-guided rotational atherectomy for unexpandable paclitaxel-eluting stent: A case report and review of literature

We describe a patient suffering from late stent thrombosis in a paclitaxel-eluting stent which had an underexpanded ring due to the three-hundred-sixty-degree circumferential calcified plaque. Intravas...     

Successful treatment of a bifurcation lesion with the Carina Bard stent: A case report.

In the last years new techniques and user-friendly stents have improved the results of stent implantation in coronary bifurcational lesions but difficulties in stent deployment and incomplete coverage of the bifurcation remain a problem. We describe the case of a proximal lesion of the anterior descending artery involving a large diagonal branch treated with the Carina Bard bifurcate stent, a new device that allows the complete immediate coverage of a bifurcational lesion with a single stent. Cathet. Cardiovasc. Intervent. 48:89-92, 1999.     

Subclavian transectional stent fracture and migration to the aortic carrefour: A case description of retrieval by snare system

Percutaneous transluminal angioplasty with or without stent has become the treatment of choice for stenotic lesion in subclavian arteries. However, there is a growing concern following many reports of stent fractures, a serious complication of endovascular therapy. We report for the first time a case of delayed left subclavian stent fracture with transection of the protruding ostial part and migration into the aortic carrefour that was retrieved by a snare device. © 2013 Wiley Periodicals, Inc.     

Successful percutaneous retrieval of a dislodged left atrial appendage occlusion device with double transseptal sheaths and biopsy bioptome

A 64‐year‐old woman underwent left atrial appendage occlusion with an Amplatzer Cardiac Plug device. Displacement of the device was detected on day 1 with transesophageal echocardiographic checking. The device became dislodged and flitted in the left atrium after unsuccessful retrieval with a snare and 12 Fr steerable transseptal sheath. A double transseptal sheath technique was then attempted. The flitting device was stabilized by one 12 Fr steerable transseptal sheath and successfully retrieved with a biopsy bioptome through another similar transseptal sheath. The patient suffered from no long‐term sequelae. © 2014 Wiley Periodicals, Inc.     

Retrieval of dislodged and disfigured transradially delivered coronary stent: report on a case using forcep and antegrade brachial sheath insertion.

We report a case of dislodged and damaged stent during transradial coronary procedure using 6 Fr device, which was successfully retrieved by using a forcep and 8 Fr antegrade brachial sheath. The disfigured and bulky stent can be removed, after their retrieval from the coronary circulation, using a forcep inserted through an 8 Fr brachial artery sheath if the radial artery is deemed too small to accommodate larger sheath.     

Successful transradial removal of an inflated coronary stent dislodged from the right coronary ostium

We describe our solution to the unusual situation of an inflated, large coronary stent (3.5 mm diameter) which became dislodged from the ostium of the right coronary artery after deployment during a transradial procedure. We discussed tips for retrieval from the radial artery while preserving the access for completion of the procedure.     

Successful closure of a coronary vessel rupture with a vein graft stent: Case report

We report a successful percutaneous closure of a brisk coronary artery rupture with a custom-made “vein graft stent,” a Palmaz-Schatz stent covered with a vein graft. This method is an elegant and effective alternative to the traditional surgical approach and should be considered whenever technically and clinically feasible. © 1996 Wiley-Liss, Inc.     

Successful deployment of a stent graft in the popliteal artery for pseudoaneurysm after acupuncture: a case report

A 71-year-old man was admitted to our hospital because of swelling and pain in his right calf developing after acupuncture for intermittent claudication. Computed tomography with contrast medium revealed a large hematoma with contrast medium leakage in his right calf. Emergent angiography demonstrated a pseudoaneurysm of the right popliteal artery with severe stenosis. Intravascular ultrasound showed lumen narrowing with a large amount of concentric plaque and disruption of the vessel wall communicating to a large cavity outside. A polytetrafluoroethylene-covered Jostent graft was deployed into the stenotic lesion across the opening into the pseudoaneurysm cavity. Subsequent angiography showed no leakage of contrast medium. This unique case of pseudoaneurysm caused by acupuncture in the popliteal artery was treated successfully by endovascular repair.     

Successful retrieval of a frayed coronary stent using the peripheral crossover technique

With the advent of modern thin-strut coronary stents, there is potential for damage to the stent structure during delivery. Fraying of the stent during unsuccessful attempts at lesion passage can be particularly problematic as re-entry into the guiding catheter may not be possible. Familiarity with techniques to retrieve damaged stents is helpful in this situation. In the present case, we describe intentional removal of a frayed stent from its balloon and subsequent retrieval using a peripheral crossover sheath.     

Successful treatment of SAPHO syndrome with adalimumab: a case report

SAPHO syndrome is a disorder involving the skin, bone and joints. The underlying causes of SAPHO are poorly understood, and treatment is, therefore, directed towards the individual symptoms. However, many patients are refractory to treatment, and new treatment options are needed. Herein, we describe a 28-year-old patient with SAPHO syndrome and palmoplantar pustulosis seen at our hospital. Treatment was initiated with non-steroidal anti-inflammatory drugs, but clinical improvement was poor. The addition of sulfasalazine and oral alendronate also failed to alleviate symptoms. We subsequently commenced treatment with adalimumab 40 mg every 15 days and suspended bisphosphonates. Following 4 weeks’ treatment with adalimumab, there was clear articular improvement and disappearance of palmoplantar pustulous lesions. Nocturnal inflammatory lumbar pain and global disease assessment were also improved. To our knowledge, this is the first report on the use of adalimumab for SAPHO. More studies are required to confirm our findings.
