Peripheral vascular complications from percutaneous transluminal coronary angioplasty: a comparison with transfemoral
1Department of Surgery, University of Medicine and Dentistry of New Jersey, Robert Wood Johnson Medical School, New Brunswick.
Insights
Percutaneous transluminal coronary angioplasty (PTCA) carries a similar risk of peripheral vascular complications as conventional cardiac catheterization. Careful management of puncture sites is crucial to prevent serious bleeding and injury.
Area of Science:
- Cardiology
- Vascular Surgery
Background:
- Peripheral vascular complications are a known risk of transfemoral cardiac procedures.
- Comparing complication rates between percutaneous transluminal coronary angioplasty (PTCA) and conventional cardiac catheterization is important for patient safety.
Observation:
- A study compared 644 PTCA patients with 2904 cardiac catheterization patients.
- Peripheral vascular complications occurred in 0.9% of PTCA patients and 1.2% of cardiac catheterization patients.
- Complication types, including hematomas, false aneurysms, and dissections, were similar across both groups.
Findings:
- PTCA and cardiac catheterization have comparable rates of peripheral vascular complications.
- Surgical repair rates were similar, but PTCA complications sometimes involved myocardial infarction or death.
- PTCA complications were surgically challenging due to large puncture sites and anticoagulation.
Implications:
- PTCA risk for vascular complications is similar to standard cardiac catheterization.
- Preventing sheath-related injury and managing hemorrhagic complications at the puncture site are critical.
- Prompt surgical intervention is necessary for concerning puncture site complications.
Abstract:
The peripheral vascular complications associated with percutaneous transfemoral coronary angioplasty were compared with those that occurred during conventional transfemoral cardiac catheterization. Among 644 patients undergoing percutaneous transluminal coronary angioplasty (PTCA), 6 patients (0.9%) suffered peripheral vascular complications, whereas 35 of 2904 patients having cardiac catheterizations (1.2%) had a peripheral vascular complication. The types of complications associated with both procedures were similar and included groin hematomas, false aneurysms, arterial dissection, arterial perforation, and neurological deficits. The frequency of surgical repair of these complications also was similar in the two groups (50% required repair for a PTCA complication, 34% were repaired after a catheterization complication). The PTCA-associated complications included one myocardial infarction and one death, whereas neither of these occurred in association with a catheterization-induced vascular complication. The surgical management of five of the six PTCA complications was difficult, largely because of the size of the sheath-related puncture site and the presence of active bleeding from the associated systemic anticoagulation. PTCA carries the same risk of development of a peripheral vascular complication as found in transfemoral cardiac catheterization. Care must be taken to prevent sheath-related injury to the aorta-iliac-femoral system and hemorrhagic complications at the puncture site are of particular concern and require urgent surgical attention.
