Morphological analysis using geometric parameters for splenic aneurysms

Background Considering the unique characteristics of splenic artery aneurysms, we hypothesized that hemodynamic forces could play an important role in splenic artery aneurysm formation and that splenic artery geometry should be correlated with aneurysm development. Methods Tortuosity of the splenic artery was evaluated three-dimensionally by calculating the curvature using software and the original modeling system. We selected 54 splenic artery aneurysm patients who had undergone thin-slice computed tomography imaging with contrast. We compared the splenic artery aneurysm group to non-vascular patients via propensity-score matching (35 patients in each group). The splenic artery length index, average curvature, and maximum curvature were analyzed. Results Splenic artery aneurysm patients tended to have a longer splenic artery and the curvature was more severe compared to the non-vascular control patients. The average curvature of splenic artery aneurysm patients was associated with the dilatation rate in female patients. Conclusion Females with a tortuous splenic artery may have an increased risk of aneurysm formation.

Aneurysms of the splenic artery represent a rare clinical entity, even though they account for 60-70% of all visceral artery aneurysms. Splenic artery aneurysms larger than 5 cm are extremely rare, and they are considered to be giant. Possible causes of splenic artery aneurysm development include: trauma, hormonal and local hemodynamic changes in pregnancy, portal hypertension, arterial degeneration, infection and postsplenectomy occurrence. Surgical treatment of giant splenic artery aneurysms includes procedures that frequently require pancreatectomy and splenectomy. We present a case of a 10.2 cm giant splenic artery aneurysm, firmly adhered to the pancreas, which was treated surgically, with spleen and pancreas preservation. SIMILAR CASES PUBLISHED: Although many cases on treatment of giant splenic artery aneurysm have been published, the majority have described additional visceral resections associated with aneurysmectomy, which is in contrast with our report. Furthermore, aneurysms reaching 10 cm in size were extremely rare.

Introduction. Although the third most common aneurysm within the abdomen, after aneurysms of the aorta and iliac arteries, splenic artery aneurysms are rare, but not exceptionally. Owing to new imaging techniques, they have been discovered with increasing frequency. Case Outline. Authors present a 47-year-old woman, multipara, who presented with left upper abdominal pain in whom X-ray showed a calcified ring in the area of distal pancreas. Selective angiography confirmed a splenic artery aneurysm of its proximal part. During an open surgery the aneurysm was excised (aneurismectomy) without immediate, early or late complications. The patient became symptom-free. Conclusion. In patients, particularly women, the multiparas who present with epigastric or left upper abdominal pain of unknown aetiology, splenic artery aneurysm has to be taken into account. Further diagnostic procedures such as plain X-ray and selective angiography in suspected cases should be performed. Surgery or other treatment modalities are to be seriously considered in all patients, particularly in those with increased risk of rupture.

Sjögren‘S Syndrome

A 40-year-old female presented with cough, exertional dyspnea, abdominal pain with distention, fatigue, dry eyes and dry mouth. Past history revealed asthma. Physical examination was normal except for tachypnea. We found leukocytosis, azygos fissure on chest X-ray along with normal pulmonary function tests and arterial blood gases. Thorax computed tomography (CT) revealed bronchiectasis and ground glass opacities in both lungs. Abdominal CT demonstrated thrombosed proximal splenic artery aneurysm. Further diagnostic procedures were done and according to the positive Schirmer test and compatible histopathologic findings of the salivary gland, diagnosis of primary Sjögren’s syndrome was established. Splenic artery aneurysm is rare occurring in less than 1% of the population that usually appears as an incidental finding. This is the first case in literature that introduces Sjögren’s syndrome as a risk factor for splenic artery aneurysm. The silent presentation of the splenic artery aneurysm should previse the clinicians that such an occurrence may cause a significant diagnostic dilemma.
