Details of type 1 intraoperative adverse events (IOAEs) (problems with target vessel cannulation) and clinical consequences

Type of IOAE	Number of events (n = 22)	Intraoperative treatment	Consequences for target vessel and related outcomes	Clinical outcomes
RA occlusion or dissection	10	Thrombolysis: 4 Thrombolysis and thromboaspiration: 2 Thrombolysis and additional stent placement: 2 Additional stent placement: 2	Remained patent: 8	Dialysis: 1 Permanently reduced renal function: 1 Temporarily reduced renal function: 2 No impact on renal function: 4
			Target vessel lost: 2	Permanently reduced renal function: 1 Temporarily reduced renal function: 1
SMA dissection	1	Additional sent placement	Remained patent	Asymptomatic
RA cannulation failure	3	—	Target vessel lost: 3	Death: 2 Permanent reduced renal function: 1
SMA cannulation failure	1	Bailout chimney stent	Remained patent	Death
RA rupture	2	Additional stent placement: 1	Remained patent	Asymptomatic
		Distal coil embolization: 1	Remained patent	Temporarily reduced renal function: 1
Other difficulties during target vessel cannulation	Difficult cannulation of both RAs Mispositioning of a scallop dedicated to SMA Scallop deployed in posterior position Two stents for two right RAs in the same fenestration RRA stented through a scallop dedicated to SMA	— — — Endovascular occlusion of the nonstented fenestration SMA stented through the same scallop	Remained patent Partial covering of the SMA Remained patent Remained patent Remained patent	Long operation, acute compartment syndrome requiring fasciotomies Reintervention for SMA stenting Asymptomatic Asymptomatic Asymptomatic
