Summary
Accidental contrast injection during angiography can cause intraseptal hematoma and myocardial infarction. Maintaining proper catheter position prevents this rare but serious complication.
Area of Science:
- Cardiology
- Interventional Radiology
- Diagnostic Imaging
Background:
- A rare complication of diagnostic cineventriculography is intraseptal hematoma and subsequent myocardial infarction.
- This complication arises from accidental contrast agent deposition during the procedure.
Observation:
- A 61-year-old male presented with unstable angina pectoris post-coronary angiography.
- Transthoracic contrast echocardiography revealed a non-perfused area and thickening in the interventricular septum.
- Cineventriculography showed contrast enhancement in the septum and pigtail catheter displacement.
Findings:
- Intramural hematoma in the interventricular septum was diagnosed.
- The hematoma resolved within 6 weeks, confirmed by echocardiography and MRI.
- The patient underwent successful stent implantation and recovered normal LV function without ischemic signs.
Implications:
- Ensuring a safe, mobile pigtail catheter position in the left ventricle is crucial during ventriculography.
- Contrast-enhanced echocardiography is highly feasible for assessing and measuring intramural hematoma, offering results comparable to MRI.
- This complication, though rare, is potentially life-threatening and highlights the importance of meticulous procedural technique.

01:18Anatomy of the Brain: Ventricles
There are hollow fluid-filled cavities known as ventricles deep inside the human brain. There are two lateral ventricles, one in each cerebral hemisphere, and each has three different projections — the anterior, inferior, and posterior horns visible from the lateral side. A thin membrane called the septum pellucidum separates the two lateral ventricles. The slender third ventricle in the diencephalon is connected to each lateral ventricle via a channel called the interventricular foramen. The...
01:22Cerebral Edema ll: Pathophysiology
Vasogenic edema is a major form of cerebral edema characterized by abnormal accumulation of fluid in the brain’s extracellular space due to disruption of the blood–brain barrier (BBB). The BBB is a specialized structure composed of endothelial cells connected by tight junctions, supported by astrocytic endfeet and a basement membrane. Under normal conditions, it tightly regulates the movement of ions, proteins, and solutes between the bloodstream and brain parenchyma. When this barrier loses...
