“…Angioscopy is also useful in detecting and distinguishing intraluminal thrombus [4][5][6][7], and it is often quoted as the diagnostic procedure of choice for this condition [8,9]. Finally, this technique has been used to assess procedural success and complications following a range of interventional procedures, including balloon angioplasty [8][9][10][11][12][13][14][15][16], atherectomy [17][18][19], laser ablation [20,21], intravascular stent placement [3,22,23], endarterectomy [24], saphenous vein grafting [25][26][27], prosthetic graft insertion [28,29], and pulmonary and systemic thromboembolectomy [30,31].…”

“…Thrombus has been documented by angioscopy in up to 70% of vein graft lesions undergoing treatment. 18 Hong et al 10 reported in their study that after an otherwise successful SVG intervention, major CK-MB elevation (defined as Ͼ5 times the normal range) occurred in 15% of patients and was associated with a significantly increased 1-year cardiac mortality rate compared with a minor rise or normal postprocedural CK-MB values (11.7% versus 6.5% and 4.8%, PϽ0.05, respectively).…”

“…Zudem ist das Plaquevolumen aufgrund der Dimension der Venengrafts oft groß und es lassen sich häufig intravasale Thromben nachweisen (18,30). Die Histomorphologie erklärt die höhere Emboliegefahr bei Katheterinterventionen an Venengrafts, die auch durch die Anwendung ablativer Verfahren (TEC, DCA, ELCA) und Stentimplantation nicht befriedigend beherrscht wird.…”

Klinische Erfahrungen mit dem PercuSurge GuardWireTM– ein neues System zur Vermeidung von peripheren Embolien bei Katheterinterventionen an degenerierten aorto-koronaren Venenbypässen

Peripheral embolization is a typical complication of catheter interventions in degenerated aortocoronary saphenous vein grafts. Alternative techniques, such as transluminal extraction catheter (TEC), directional coronary athrectomy (DCA) and eximer laser angioplasty (ELCA) were not able to reduce the risk of peripheral vessel occlusion or "no-reflow". For the protection from peripheral embolisation we used the PercuSurge GuardWire Temporary Occlusion & Aspiration System (PercuSurge Inc., Sunnyvale, USA) in 55 patients with 58 stenosis in degenerated saphenous vein grafts. The primary endpoint of this consecutive series was to access the efficacy of the system by post-interventional TIMI flow and determination of serial CK/CK-MB. The intervention was primarily successful in 55 of 58 cases (94.8%), with a reduction in stenosis from 87.6% (range 75-100%) to 4.5% (range 0-40%). TIMI flow improved from a mean of 2.1 +/- 1.4 to 2.9 +/- 0.4 after intervention. CK/CK-MB levels were 24/5, 27/7 and 26/6 U/l (mean values) before, 8 hours, 16 hours and 24 hours after intervention, ruling out myocardial ischemia. Three (5.2%) non-q wave infarctions occurred in this series, twice caused by a peripheral embolization during the crossing of the lesion with the wire und once because of "no-reflow". In the latter case the occlusion balloon had to be deflated before the aspiration could be performed. In 80 of 92 aspirates (86.9%) macroscopic embolic debris was visible. The PercuSurge GuardWire Temporary Occlusion & Aspiration System is a safe and effective device for the protection of distal embolization during interventions in degenerated aorto-coronary saphenous vein grafts.

Percutaneous angioscopy of saphenous vein coronary bypass grafts

Abstract: We conclude that angioscopy is superior to angiography for detecting complex lesion morphology in bypass grafts and that the presence of friable plaque does not preclude an uncomplicated angioplasty procedure.
