Guide catheter induced dissection of coronary arteries is an uncommon, but serious complication of coronary angioplasty. Treatment can include emergent coronary artery bypass grafting to the affected vessel or percutaneous intervention including wiring the true lumen and exclusion stenting of the dissection flap to prevent further propagation. Detailed descriptions have been published of techni...

Background: Arterial catheters are frequently needed to optimize the intensive care in sick newborn. Umbilical Catheters (UAC) is more popular than peripheral arterial catheterization. They utilized provide continuous accurate blood pressure monitoring, frequent assessment of gas exchange efficiency, sampling and rarely for transfusion. may be used emergencies infuse fluids or medications absen...

Endovascular treatment options for dural arteriovenous fistulas (DAVFs) have vastly expanded and become progressively safer in the last several years. Angiographic imaging systems have improved, catheter technology has advanced, and liquid embolic and coil options have increased. As a likely result, an increasing proportion of DAVFs are treated via an endovascular approach. In addition to allow...

Obstruction of blood flow in the superior vena cava (SVC) results in symptoms and signs of SVC syndrome. SVC obstruction can be caused either by invasion or external compression of the SVC by contagious pathologic processes involving the right lung, lymph nodes, and other mediastinal structures, or by thrombosis of blood within the SVC. Occasionally, both mechanisms co-exist. We hereby report a...

OBJECTIVE Since the introduction of multilumen central venous catheters two decades ago, there has been controversy whether the additional lumens place patients with these catheters at higher risk for infection. Our objective was to determine the risk of catheter-related bloodstream infection (CRBSI) and catheter colonization in multilumen catheters compared with single-lumen catheters. DATA ...

INTRODUCTION Genital abnormalities have been reported in up to 12 percent of men with unilateral renal agenesis.(1) There have also been reports of neurofibromatosis patients manifesting ipsilateral renal agenesis.(2) Abnormal development of the mesonephric duct between the fourth and thirteenth week of embryonic life seems to be the origin of such cysts, which can have a variable clinical pres...

A female patient with end-stage renal failure, who was maintained on haemodialysis via multiple central dialysis catheters, developed chronic occlusion of the left brachiocephalic vein. Subsequently, the right jugular dual lumen PermCath became dysfunctional because of marked superior vena cava stenosis. Angioplasty of the superior vena cava stenosis was performed but failed to restore adequate...

Nitric oxide (NO) releasing polymers are promising in improving the biocompatibility of medical devices. Polyurethanes are commonly used to prepare/fabricate many devices (e.g., catheters); however, the transport properties of NO within different polyurethanes are less studied, creating a gap in the rational design of new NO releasing devices involving polyurethane materials. Herein, we study t...

OBJECTIVES The objective of this study was to compare 2 manual thrombus aspiration catheters in unselected patients with ST-segment elevation myocardial infarction. BACKGROUND Distal embolization is common during percutaneous coronary intervention in ST-segment elevation myocardial infarction and can induce impaired myocardial perfusion. Several aspiration thrombectomy devices have been intro...

INTRODUCTION Intravascular cooling and warming catheters are among a range of proliferating technologies used for temperature control. Complications related to the use of these devices are few, and no definitive evidence has been presented thus far to indicate any differences in complication rates between these balloon catheters and other central vein catheters. We report two cases of cooling a...
