Severe hemolysis following partial coil-occlusion of patent ductus arteriosus

Abstract

Severe hemolysis occurred in a one‐year‐old boy following partial coil occlusion of a patent ductus arteriosus with a small but high‐velocity residual shunt. Hemolysis abated rapidly and completely after placement of a second coil fully occluded the ductus. © 1996 Wiley‐Liss, Inc.

Conservative Treatment of Hemolytic Complication Following Coil Embolization in Two Adult Cases of Patent Ductus Arteriosus.

“…In a large PDA, there is a greater possibility that the ductal shunt flow will remain even when multiple embolization coils are used and if this occurs, the placement of additional coils is recommended. 4,5,14,15 If the additional coils cannot be inserted, the arterial canal must be closed surgically. 7 Retrieval of the embolized coils through a catheter is another option, but is not recommended when multiple coils are implanted because of the high risk of migration of the coils.…”

“…2,3 Serious complications of coil embolization are coil migration and hemolysis caused by a residual shunt, 4,5 the latter being reported as the major complication with approximately 1-2% occurrence. 2,6,7 Although a hemolytic complication usually needs additional coil embolization 4,5 or surgical treatment, medical treatment may be preferable when the residual shunt is minimal and the degree of hemolysis is mild. We report 2 cases of large PDA that were treated by multiple coil embolization, complicated by hemolysis, but successfully managed by medical treatment.…”

Transcatheter Occlusion of Patent Ductus Arteriosus With a New Detachable Coil System (DuctOcclud)

“…23 Hemolysis related to incomplete occlusion with a Gianturco coil or a Cook detachable coil has been reported. 24,25 It is unclear why hemolysis is uncommon shortly after implantation, despite the relatively high incidence of residual shunt. Thrombi adhering to the unfibered surface of DuctOcclud coil are finer than those adhering to fibered coils (personal communication), which may decrease the risk of hemolysis with residual shunt.…”

Late coil migration due to thrombolysis after successful implantation of a coil for persistent ductus arteriosus

“…The results of coil implantation to close the PDA shunt have been encouraging [3]. However, there are some serious complications such as coil migration into the pulmonary or systemic arteries and hemolysis [4]. We report here a case of late coil migration 1 week after successful implantation of the coil and discuss possible etiology and prevention of this complication.…”
