Spontaneous Dissection of the Splanchnic Arteries: CT Findings, Treatment, and Outcome

Abstract

Intimal flap, thrombosed false lumen, and aneurysmal dilatation are the most common CT findings of spontaneous splanchnic artery dissection. In splanchnic artery dissection, conservative management without anticoagulation had good outcome except in patients with bowel ischemia, aneurysmal dilatation three times larger than a normal segment, or progression of dissection.

Spontaneous dissections of multiple visceral arteries: an extremely rare case

“…Most of the information on isolated spontaneous dissections of the visceral arteries comes from sporadic case reports of single artery dissections, mostly involved the splanchnic artery [1256]. To the best of our knowledge, this is the first report on multiple simultaneous visceral artery dissections which have endured the longest follow-up without event (84 months).…”

“…An isolated visceral artery dissection refers to the absence of an aortic dissection at initial presentation and the risk factors for an arterial dissection [12]. Single dissection of the visceral arteries are infrequent [34].…”

“…Single dissection of the visceral arteries are infrequent [34]. Multiple spontaneous isolated dissections of the visceral arteries are therefore considered extremely rare [256]. We report a case of multiple spontaneous dissections involving the superior mesenteric artery (SMA), the celiac artery (CA) and bilateral renal arteries (RA).…”

Spontaneous Isolated Visceral Artery Dissection in a Middle Aged Male

“…Patients may have tenderness to abdominal palpation but usually do not exhibit peritoneal signs. Contrast-enhanced abdominal CT is the imaging modality of choice and the most common imaging findings are presence of an intimal flap, false lumen thrombosis, or aneurysmal dilatation [2, 9]. Misdiagnosis can occur even with contrast-enhanced CT [10].…”

Angioscanner tridimensionnel des artères splanchniques : avantages et limites

“…La plupart des dissections peuvent être prises en charge avec succès au moyen d'un traitement conservateur comportant l'observation ou une anticoagulation [74]. Un traitement chirurgical ou une intervention percutanée doit être réservé aux patients présentant une ischémie mésentérique sévère et à ceux chez qui le traitement conservateur initial a échoué [74,75].…”
