Severely Calcified True Aneurysm: A Thought-Provoking Case of Solitary Origin and Postoperative Management

Splenic artery aneurysm: a rare complication of autosomal dominant polycystic kidney disease

Autosomal dominant polycystic kidney disease (ADPKD) is an important cause of renal dysfunction. It is the most common genetic disorder leading to end-stage kidney disease requiring dialysis. ADPKD is a multisystem disease and is linked to several extra renal abnormalities. Splenic artery aneurysms are rare in the general population. ADPKD is associated with cerebral artery aneurysms. However, splenic artery aneurysms are not a well-recognised complication of ADPKD. We report an unusual case of a splenic artery aneurysm found incidentally on abdominal CT imaging of a woman with known ADPKD.

Spontaneous rupture of a large splenic artery aneurysm in a 59-year-old male patient with pemphigus vulgaris: a case report

Background

There is currently no information on the anatomical risk factors for splenic artery aneurysm rupture, specifically the location or size of the lesion; therefore, reporting this entity to obtain data and ultimately reduce morbidity and mortality is essential. Here we report a case of a male patient with spontaneous rupture of a large splenic artery aneurysm presenting with abdominal pain.

Case presentation

A 59-year middle-eastern male, with known pemphigus vulgaris presented with a chief complaint of headache and syncope, followed by abdominal pain along with severe metabolic acidosis. A contrast-enhanced computed tomography scan of the abdomen and pelvic showed a splenic artery aneurysm of 33 × 30 mm with a 150 × 90 mm hematoma formation around the aneurysm site. The patient underwent an operation and splenectomy, with confirmation of the diagnosis of ruptured splenic artery aneurysm.

Conclusion

It is essential to consider splenic aneurysm rupture as a second-line differential diagnosis, especially among patients with comorbid diseases, as this can lead to timely and appropriate lifesaving intervention.

Fatal arterial hemorrhage after pancreaticoduodenectomy: How do we simultaneously accomplish complete hemostasis and hepatic arterial flow?

BACKGROUND

Although arterial hemorrhage after pancreaticoduodenectomy (PD) is not frequent, it is fatal. Arterial hemorrhage is caused by pseudoaneurysm rupture, and the gastroduodenal artery stump and hepatic artery (HA) are frequent culprit vessels. Diagnostic procedures and imaging modalities are associated with certain difficulties. Simultaneous accomplishment of complete hemostasis and HA flow preservation is difficult after PD. Although complete hemostasis may be obtained by endovascular treatment (EVT) or surgery, liver infarction caused by hepatic ischemia and/or liver abscesses caused by biliary ischemia may occur. We herein discuss therapeutic options for fatal arterial hemorrhage after PD.

AIM

To present our data here along with a discussion of therapeutic strategies for fatal arterial hemorrhage after PD.

METHODS

We retrospectively investigated 16 patients who developed arterial hemorrhage after PD. The patients’ clinical characteristics, diagnostic procedures, actual treatments [transcatheter arterial embolization (TAE), stent-graft placement, or surgery], clinical courses, and outcomes were evaluated.

RESULTS

The frequency of arterial hemorrhage after PD was 5.5%. Pancreatic leakage was observed in 12 patients. The onset of hemorrhage occurred at a median of 18 d after PD. Sentinel bleeding was observed in five patients. The initial EVT procedures were stent-graft placement in seven patients, TAE in six patients, and combined therapy in two patients. The rate of technical success of the initial EVT was 75.0%, and additional EVTs were performed in four patients. Surgical approaches including arterioportal shunting were performed in eight patients. Liver infarction was observed in two patients after TAE. Two patients showed a poor outcome even after successful EVT. These four patients with poor clinical courses and outcomes had a poor clinical condition before EVT. Fourteen patients were successfully treated.

CONCLUSION

Transcatheter placement of a covered stent may be useful for simultaneous accomplishment of complete hemostasis and HA flow preservation.

Spontaneous Rupture of a Huge Splenic Artery Aneurysm: A Case Report

BACKGROUND Splenic artery aneurysm is uncommon in a healthy young male patient. With spontaneous rupture, it can quickly become life-threatening. Our aim is to highlight the possibility of splenic artery aneurysm among healthy young patients and its presentation as recurrent abdominal pain, while pending rupture is possible, which can present a diagnostic challenge. The rare occurrence and spontaneous rupture of a splenic artery aneurysm are often fatal outside an inpatient setting. CASE REPORT Here, we present the case of a 32-year-old patient who visited the Emergency Department with recurrent epigastric pain. While undergoing inpatient evaluation, had a spontaneous rupture of a splenic artery aneurysm with hypovolemic shock and a double-rupture phenomenon, necessitating emergency surgery. CONCLUSIONS With advances in modern imaging in recent years, the incidence of splenic aneurysm has increased 7-fold; therefore, being informed and considering it in the differential diagnosis might provide a window of opportunity and save lives.
