Table 2. Demographics, EGD and CT findings, EGD and interventional radiology intervention, and clinical outcome of cases 6 to 10.

CT: computed tomography; GDA: gastroduodenal artery; IPDA: inferior pancreaticoduodenal artery; SMA: superior mesenteric artery.

	Case 6	Case 7	Case 8	Case 9	Case 10
Age (years)	65	55	53	67	59
Gender	Male	Male	Male	Male	Male
Presenting complaint	Melena	Hematemesis	Melena	Hematemesis	Hematochezia
EGD findings	Few nonbleeding duodenal ulcers and one oozing duodenal ulcer with a visible vessel ( Forrest Ib)	Multiple dispersed nonbleeding erosions with no stigmata of recent bleeding, and one oozing cratered 30 mm duodenal ulcer (Forrest Ib)	One bleeding duodenal ulcer, one oozing duodenal ulcer (Forrest Ib) and one nonbleeding duodenal ulcer	Large friable necrotic, malignant-looking infiltrative bleeding mass in duodenum	One bleeding cratered duodenal ulcer with a visible vessel in the duodenal bulb  (Forrest IIa)
EGD intervention	Epinephrine injection and electrocautery	Epinephrine injection. Thermal therapy deferred due to risk of perforation	Clips placed	None	Epinephrine injection and electrocautery
CT abdomen findings	Hyperdense material seen within the second portion of the duodenum	Dense-fluid-filled duodenal wall thickening and ulceration crater	Hypertrophic submucosal arterioles along the second portion of the duodenum	Infiltrative mass with active bleeding in the second part of the duodenum	Hypertrophic submucosal arterioles along the duodenum
Angiogram findings	Irregularly tortuous duodenal arterioles as the culprit of bleeding from branch of the gastroduodenal artery (GDA) with hypertrophic inferior pancreaticoduodena artery (IPDA) shunting toward the superior mesenteric artery (SMA)	Many focal bleeding blush adjacent to endoscopic clip	Irregularly tortuous duodenal arterioles as the culprit of bleeding from branch of the GDA with shunting toward the SMA	Active duodenal bleeding from IPDA coming off GDA	irregular and spastic GDA with questionable focal bleeding blush adjacent to endoscopic clips
Interventional radiology intervention	Particulate polyvinyl alcohol (PVA) 500 micron particle used in the GDA	1 coil and 2 vascular plugs deployed along the GDA	Particulate PVA 500 micron particle used in the GDA	5 coils deployed along IPDA beyond the takeoff of gastroepiploic artery	1 coil and 2 vascular plugs deployed along the GDA
Outcome	Expired - likely due to severe sepsis with septic shock secondary to pneumonia from multidrug-resistant gram-negative organism	Alive with no further known duodenal bleeding episodes after angioembolization	Expired - likely due to  severe sepsis with septic shock secondary to multifocal pneumonia	Alive with no further known duodenal bleeding episodes after angioembolization	Expired - likely due to  respiratory failure due to left lung collapse secondary to endobronchial lesion
