Successful collapse vessel treatment with a syringe for thrombus-aspiration after the guidewire-induced coronary artery perforation

Coronary artery perforation is a rare however potentially life-threatening complication of percutaneous coronary intervention that could cause cardiac tamponade. It requires emergent surgery unless an appropriate procedure is performed immediately. In distal coronary artery perforations with guidewires, several procedures were reported to be effective in refractory cases after prolonged balloon inflation and reversal of heparin by protamine sulfate to induce hemostasis. We describe a case of successful collapse distal coronary artery treatment with a syringe for thrombus-aspiration without materials for an embolization after guidewire-induced coronary artery perforation.

Management of guidewire‐induced distal coronary perforation using autologous fat particles versus coil embolization

Distal coronary perforation is a rare, yet potentially lethal complication of percutaneous coronary intervention. Early recognition and treatment remains critical in preventing potentially life‐threatening adverse outcomes, such as cardiac tamponade. The most commonly used strategies for treating distal perforation are fat and coil embolization. We present two cases of guidewire‐induced distal coronary perforation and discuss the advantages and disadvantages of coil vs. fat embolization. © 2016 Wiley Periodicals, Inc.     

Coronary artery perforation repair using microcoil embolization

An 82-year-old woman undergoing percutaneous transluminal coronary angioplasty experienced perforation of the terminal portion of the left anterior descending coronary artery caused by guidewire trauma. The coronary artery perforation was successfully closed using a vascular occlusion system consisting of individual thrombogenic coils delivered to the site. Coronary artery perforation (CAP) during percutaneous transluminal coronary angioplasty (PTCA) has been reported to occur in less than 1% of cases. The incidence seems to be higher with the new interventional devices, e.g., DCA, TEC, and laser CAP may result in pericardial hemorrhage and cardiac tamponade or a coronary artery fistula to either the left or right ventricle. The management of CAP may include prolonged balloon inflations, reversal of anticoagulation, pericardiocentesis, and emergency surgery. Proximal perforations sometimes can be managed with vein covered stents. We describe another option in the treatment of distal CAP using a vascular occlusion system. Cathet. Cardiovasc.

Guidewire-induced coronary artery perforation treated with transcatheter injection of polyvinyl alcohol form.

We describe a first case of successful transcatheter management of guidewire-induced distal coronary artery perforation and impending cardiac tamponade, which developed during percutaneous coronary angioplasty, with transcatheter injection of polyvinyl alcohol form. This method may be an effective alternative in the management of distal coronary artery perforation requiring surgical repair.     

Coronary artery perforation: How to treat it?

Coronary artery perforation fortunately represents a rare complication of coronary catheterization but, if not properly and promptly treated, it is burdened by a high mortality rate. Rates of coronary perforation may be potentially higher when atherectomy devices are used or very complex calcified lesions are treated. Cardiac tamponade constitutes the most severe clinical consequence.We report the case of an intra-stent coronary perforation at the end of revascularization of a non-ST elevation myocardial infarction (NSTEMI), followed by an immediate impairment of hemodynamic compensation, due to significant pericardial effusion and subsequent cardiac tamponade.The use of covered stents has revolutionized the management of coronary perforation and this has meant that the use of emergency CABG has decreased over the years with satisfactory immediate and short-term outcomes, reducing the incidence of acute cardiac tamponade and mortality without surgery.     

Successful management of osteal perforation of left anterior descending artery with coated stent

Coronary perforation is a rare complication of percutaneous coronary intervention. We report a case of left anterior descending artery osteal perforation that led to acute cardiac tamponade during excimer laser angioplasty. Perforation was successfully covered with a PTFE-coated stent with preserved distal coronary flow.     

Recurrent cardiac tamponade following unusual micro leak after successful closure of the primary leak

Although uncommon, coronary artery perforation is one of the most dreadful complications of percutaneous coronary intervention, which requires prompt, aggressive, and effective management. Perforations induced by coronary guidewires are usually located in the distal part of a coronary artery and commonly managed with embolization. This is an unusual case report of guidewire-induced coronary perforation with recurrent cardiac tamponade, which was managed successfully by coil embolization of both ipsilateral and contralateral coronary arteries via transradial approach.     

Gelfoam embolization of a distal coronary artery guidewire perforation.

A guidewire-induced distal coronary artery perforation presenting with cardiac tamponade was occluded by distal Gelfoam embolization via an infusion catheter. This extends the treatment options for this rare complication of coronary interventional procedures. Cathet. Cardiovasc. Intervent. 49:214-217, 2000.     

A unique complication of the retrograde approach in angioplasty for chronic total occlusion of the coronary artery

The retrograde approach for chronic total occlusion of coronary arteries is a new treatment strategy, although its attendant complications have not yet been fully appreciated. We report a case of isolated left ventricular cardiac tamponade caused by guidewire‐induced perforation of the septal branch during the retrograde approach, which was subsequently diagnosed by computed tomography (CT) and which required surgical drainage. Guidewire‐induced perforation of the septal branch was successfully treated by autologous subcutaneous tissue embolization of the perforated coronary artery. This is the first case of its kind to date. © 2008 Wiley‐Liss, Inc.     

Complete left atrial obliteration due to localized tamponade after coronary artery perforation during PTCA

Coronary artery perforation is a rare but important complication of percutaneous revascularization (PTCA). Clinical events following coronary perforation may include cardiac tamponade. After bypass graft operation (CABG), however, cardiac tamponade with subsequent hemodynamic instability is unusual due to the development of pericardial adhesions. We report an unusual case of localized tamponade after coronary artery perforation during PTCA in a patient with previous CABG. Cathet. Cardiovasc.

Novel economic treatment for coronary wire perforation: A case report

BACKGROUNDCoronary artery perforation is a rare but potentially life-threatening complication of percutaneous coronary intervention (PCI), however if recognized and managed promptly, its adverse consequences can be minimized. Risk factors include the use of advanced PCI technique (such as atherectomy and chronic total occlusion interventions) and treatment of severely calcified lesions. Large vessel perforation is usually treated with implantation of a covered stent, whereas distal and collateral vessel perforations are usually treated with embolization of coils, fat, thrombin, or collagen. We describe a novel and cost-effective method of embolisation using a cut remnant of a used angioplasty balloon that was successful in sealing a distal wire perforation. we advocate this method as a simple method of managing distal vessel perforation.CASE SUMMARYA 73-year-old male with previous coronary Bypass graft operation and recurrent angina on minimal exertion had undergone rotablation and PCI to his dominant left circumflex. At the end of the procedure there was evidence of wire perforation at the distal branch and despite prolonged balloon tamponade there continued to be extravasation and the decision was made to seal this perforation. A cut piece of an angioplasty balloon was used and delivered on the original angioplasty wire to before the perforation area and released which resulted in sealing of the perforation with no unwanted clinical consequences.CONCLUSIONThe use of a balloon remnant for embolization in coronary perforation presents a simple, efficient and cost-effective method for managing coronary perforations and may be an alternative for achieving hemostasis and preventing poor outcome. Prevention remains the most important part with meticulous attention to the distal wire position, particularly with hydrophilic wires.     

Successful treatment of coronary artery perforation during angioplasty using autologous vein graft-coated stent

We report a case of successful treatment of coronary arteryperforation and cardiac tamponade with an autologous vein graft-coatedstent, which were developed during percutaneous transluminalcoronary angioplasty. The method reported here may be an effectivealternative to emergency surgery and should be considered whencoronary artery perforation does not respond to conventionalprolonged inflation with perfusion catheter.     

ST-elevation myocardial infarction caused by coronary artery compression due to localized pericardial hematoma caused by coronary perforation

Coronary perforation is a rare but serious complication of percutaneous coronary intervention (PCI). We report a case of coronary perforation during PCI in a post cardiac surgery patient presenting as unusual ST-segment elevation myocardial infarction, secondary to compression of an epicardial artery by a localized hematoma, secondary to coronary perforation by the guidewire.

Distal coronary artery perforation resulting from the use of hydrophilic coated guidewire in tortuous vessels

We describe our experience with the ChoiCE PT (Boston Scientific Corporation, MN) guidewire, which resulted in perforation of the distal coronary artery in two instances. This newly introduced guidewire differs from earlier guidewires in its ability to cross lesions in tortuous arteries. However, when it buckles deep in the coronary artery, perforation can easily result. While the ChoiCE PT guidewire is a useful addition to our armamentarium in interventional procedures, it should be treated with care. Cathet. Cardiovasc.

Successful treatment of distal coronary guidewire-induced perforation with balloon catheter delivery of intracoronary thrombin.

Distal coronary artery perforation with a coronary guidewire is a relatively rare but potentially fatal complication during PTCA. Historically, these types of perforations have been easy to control with reversal of heparin anticoagulation combined with prolonged distal balloon inflation. In the modern era, with widespread use of potent glycoprotein IIb/IIIa inhibitors, this type of distal wire perforation has become more difficult to manage and potentially lethal. In this article, we report two cases of guidewire-related distal coronary artery perforation, successfully treated using a new technique using localized, distal intracoronary thrombin injection. During prolonged low-pressure balloon inflation, a small dose of thrombin was injected just proximal to the wire perforation site via the lumen of a coronary balloon catheter. This approach appears to be a relatively rapid and effective way to control this troublesome complication.     

Cardiac tamponade following percutaneous transluminal coronary angioplasty: four case reports

Percutaneous transluminal coronary angioplasty (PTCA) has had complications related to dilating catheters and guide wires such as coronary artery dissection, spasm, rupture, and perforation. This report describes four patients who developed cardiac tamponade following PTCA, presumably from right ventricular (RV) perforation. All four received large doses of heparin during PTCA and three received antiplatelet therapy. In three cases, cardiac tamponade occurred several hours after PTCA. All patients did well following operative intervention and no patient required repair of a cardiac perforation. We postulate that impaired hemostasis in the presence of an otherwise inconsequential RV perforation causes tamponade. Three alternatives to provide standby pacing are proposed.     

Delayed coronary perforation four days after percutaneous coronary intervention with subsequent cardiac tamponade: A case report

Coronary artery perforation (CAP) is a rare but lethal complication of percutaneous coronary interventions (PCIs), and its incidence has been increasing with advances in PCI techniques. Delayed CAP presents a highly challenging complication, as it occurs 30 min−9 days after intervention, making subsequent diagnosis and treatment difficult. We present the case of a 63-year-old male patient who underwent PCI for an obtuse marginalis II because of posterior wall myocardial infarction. Following 4 days of uneventful postoperative stay, the patient developed angina pectoris and hypotension 4 h after reinitiation of anticoagulant therapy with edoxaban. Angiography revealed distal vessel perforation from a side branch of the obtuse marginalis II. The vessel was occluded using autologous fat embolization via a microcatheter, resulting in complete sealing of the perforation. After discharge, 4 weeks after the infarction, the patient started rehabilitation therapy. Distal vessel perforations are typically caused by wire damage. In our case, we also suspected distal wire perforation, which was initially not recognized possibly due to distal occlusion through the thrombotic material. The temporal correlation between the re-initiation of anticoagulant therapy and the occurrence of cardiac tamponade suggests that the thrombotic material was resolved due to the former. The management of delayed CAP does not differ from that of CAP; thus, this rare complication should be considered even days after PCI as it could prove lethal if not recognized early.     

经皮冠状动脉介入治疗并发冠状动脉穿孔25例分析

目的 探讨经皮冠状动脉介入治疗（PCI）并发冠状动脉穿孔的处理策略。方法纳入2004年5月至2010年10月行PCI治疗并发冠状动脉穿孔的25例患者,对患者的临床资料进行回顾性分析,根据穿孔的影像特征进行Ellis分型,对各型冠状动脉穿孔的处理策略进行分析与总结。结果冠状动脉穿孔的发生率为0.82%（25/2036）,其中Ⅰ型穿孔13例（52%）,Ⅱ型穿孔3例（12%）,Ⅲ型穿孔9例（36%）,死亡2例（8%）。Ⅰ型穿孔患者采取严密观察,但未行特殊处理。Ⅱ型穿孔患者予以停用抗凝药物,球囊长时间低压扩张,其中1例于术后24h出现心包填塞,心包穿刺引流后病情逐渐稳定。Ⅲ型穿孔患者4例经球囊低压力贴附封堵穿孔部位后破口消失,3例行带膜支架置入,2例在球囊长时间低压力贴附封堵穿孔部位同时使用鱼精蛋白,但使用鱼精蛋白后均出现冠状动脉内慢血流死亡;Ⅲ型穿孔患者中4例出现急性心包填塞。结论冠状动脉穿孔发生率低,但可导致严重临床后果,及时正确处理是减少恶性心脏事件的关键。
