Patient, aneurysm and procedural characteristics

Pt no	Age	Loc	SAH	Side	Size (mm)	DAC Pos	Occl	Comp	DAC evaluation (comments from operators)
1	Late 30s	VBJ	N	R	11.6	IC VA	Compl	N	Practical and helpful
2	Mid-50s	PICA	Y	R	6.1	IC VA	Near-Compl	N	Practical and helpful
3	Mid-60s	OphthA	Y	L	6.0	IC ICA	Near-Compl	N	Practical and helpful
4	Mid-40s	PICA	Y	L	6.3	IC VA	Compl	N	Practical and helpful
5	Mid-40s	AchA	Y	L	3.7	IC ICA	None	N	Practical, however coiling not possible because of wide necked aneurysm; coil did not stay, aborted
6	Mid-60s	AcomA	N	R	5.1	IC ICA	Compl	N	Practical and helpful
7	Late-50s	OphthA	N	R	3.6	IC ICA	Compl	N	Practical and helpful
8	Mid-60s	PICA	N	L	10	IC VA	Compl	N	4.3 Fr DAC in 6 Fr Envoy, could not inject through the guide (suboptimal road map), coiled without DAC
9	Mid-80s	PcomA	N	R	25	IC ICA	None	Y TempACA occl	DAC successfully positioned in cavernous ICA, failure to navigate siphon with microcatheters for stent deployment (residual aneurysm), temporary ACA occl, successful thrombectomy/thrombolysis, stent assisted coiling procedure aborted, patient remained asymptomatic
10	Mid-40s	SCA	Y	R	6.6	IC VA	Compl	N	Practical and helpful
11	Mid-50s	AcomA	N	L	4.5	IC ICA	None	N	Practical, but coils did not stay within the wide necked aneurysm safely and thus were withdrawn without complication; endovascular procedure aborted; aneurysm was later clipped successfully
12	Early 40s	AcomA	Y	R	4.9	IC ICA	Compl	N	Practical and helpful
13	Late 40s	OphthA	N	L	4.0	IC ICA	Near-Compl	N	Practical and helpful
14	Early 70s	ACA	N	L	3.5 (residual after previous coiling)	IC ICA	Compl	N	Practical and helpful
15	Mid-50s	Sup hyp	N	R	8.0	IC ICA	Compl	N	Practical and helpful
16	Late 50s	MCA	Y	L	3.5	MCA	Compl	N	Practical and helpful
17	Mid-60s	Peri calA	Y	L	4	IC ICA	Compl	N	Practical and helpful
18	Early 70s	AcomA	N	L	11	IC ICA	Compl	N	Practical and helpful
