A Knot of the Central Catheter Created During Usage Period
Journal of Medical Cases, 2011
The use of central veins catheters for diagnostic and therapeutic purposes is a common procedure in intensive care unit (ICU) and operating rooms. This procedure, even if performed by skillful hands, might cause complications during the insertion maneuvre or in the course of use. Preventing and decreasing the rate of the complications requires a correct technique application, from the insertion to the withdrawal procedure of the catheter. We are describing a rare complication case, which occurred a few days after the insertion of the catheter. The mechanisms of the presented complication must be rare, but is potentially possible.
A Formation of a true knot in subclavian venous catheter in a patient in the intensive care unit
2020
Vascular catheters installation is most frequently used in critical care units. A node in the catheter lumen is a rare mechanical complication of the central venous catheterization. The 14-year-old was treated for acute appendicitis complicated by diffuse purulent peritonitis. It was decided to install a central venous catheter on the very first day of treatment. A catheterization of the right subclavian vein according to Seldinger was carried out. The catheter functioned properly for 6 days. On the 7th day, in the process of removal of the catheter, its extraction was blocked at a 1 cm depth from the tip. The catheter was removed by strong physical force with the occurrence of a hematoma in the area of installation of the catheter. Once removed, on the catheter there was found a node, formed inside the vessel. In this case, no disabling and life-threatening complications as a result of the use of the catheter were recorded. In the future, the patient was discharged recovered.
Formation of a true knot in subclavian venous catheter in a patient in the intensive care unit
Anaesthesia, Pain Intensive Care, 2020
Vascular catheters are most frequently used in the critical care units. A true knot in the catheter is a rare mechanical complication of the central venous catheterization. A 14-year-old patient was treated for acute appendicitis complicated by diffuse peritonitis. It was decided to insert a central venous catheter on the first day of treatment. A catheter was inserted in the right subclavian vein according to Seldinger technique. It functioned perfectly for 6 days. On 7th day, during its removal, its extraction was blocked at about 1 cm depth from the tip. The catheter had to be removed forcefully with the formation of a hematoma at the entry point of the catheter. Once removed, we found a true knot formed tightly inside the vessel. In this case, no disabling and life-threatening complication was recorded, and the patient was discharged when fully recovered. Citation: Shkurupii DA, Kholod DA.

IHJ Cardiovascular Case Reports (CVCR), 2018
Transradial approach for coronary intervention has gained popularity amongst experienced as well as upcoming interventional cardiologist. As compared to femoral access, the radial access has many advantages. Although like any other procedure, transradial approach is also not free of complications. Many vascular anomalies and complications are described, which includes radial artery spasm, tortuous course of axillary or subclavian artery, arteria lusoria, intimal dissection, perforation, compartment syndrome and rarely pseudoaneurysm formation. A few cases had been reported about kinking/twisting of radial catheter followed by trapping of catheter in the radial artery. Here we present such unusual case of an entrapped catheter in the radial artery and its successful retrieval with the help of goose snare. We would also like to propose a stepwise approach in such a case scenario.
Simple nonsurgical method of reduction of coronary catheter knot
Journal of Cardiovascular Disease Research, 2013
Knotting and kinking of the coronary catheter is one of the complications during diagnostic or interventional procedures. These complications can be tackled percutaneously without subjecting the patient to surgery. We are reporting one such case of catheter knotting and how it was reduced percutaneously.
Removal of Knotted Intravascular Devices. Case Report and Review of the Literature
European Journal of Vascular and Endovascular Surgery, 2002
Objective: to review published reports on knotted intravascular devices/catheters. Method: report of two cases and systematic review of the literature. Results: a total of 113 reported cases of knotted intravascular devices/catheters were located. Pulmonary artery catheters (Swan-Ganz) were responsible for more than two thirds of the total reported intravascular knots. In 62% (70/113) of the cases withdrawal of the knotted catheters was achieved successfully with different interventional radiological techniques, avoiding the need for surgical exploration. In 32% (36/113) of the patients surgical removal was favoured. Capture with one of the interventional techniques and pulling down the knot into an easily accessible vein to be removed through an open venotomy, was the most common surgical procedure. However, in five cases, an open cardiotomy was required. In seven cases the patient's condition was critical and precluded any surgical procedure, so the knotted catheter was left in situ. The mortality of this event was 8% (9/113). Conclusions: interventional radiological techniques have largely replaced open surgical removal. Knotted catheters may need to be surgically removed when (a) the knot is large in size with many loops, or (b) intracardiac fixing of the knot is encountered.
Jugular Venous Catheterization: A Case of Knotting
Case Reports in Medicine, 2015
A 79-year-old woman, diagnosed for cancer of the ovary, had a central catheter that was placed with difficulty through the right internal jugular vein intraoperatively. After oophorectomy, it was realized that the catheter was knotted. Thus, the central venous catheter was removed successfully using a traction technique in the operating room. Central venous catheter use may result in various complications, although it has been used as an invasive method for hemodynamic monitoring and fluid and drug infusion. Here, we present catheter knotting in a case with solutions for this complication, under literature review.
Knotting and Entanglement of Multiple Central Venous Catheters
2016
ABSTRACT. A 53-yr-old black male was admitted with pe-ripheral vascular disease and septic shock. Appropriate cardio-pulmonary resuscitation and operative intervention required the placement of mutiple central venous lines. These included two subclavicular central venous pressure (CVP) catheters and one Swan-Ganz catheter (SGC). During manipulation of the SGC, it formed a knot with the two CVP catheters entangled in it. After consideration of the variety of strategies that could be employed, the CVP catheters were manually disengaged from the knot and the knot was surgically removed. The in-creasing frequency and multiple central angioaccess catheters will result in a finite increase in the nature and complexity of the clinical challenges. The insistence on the use of multiple single-channel catheters for separate therapeutic functions and the duration of stay of pulmonary catheters should be reconsid-ered.
