“…The non-invasiveness and short acquisition time of CTA give it more advantages for acute bleeding and a higher priority than DSA (18,19). However, some literature points out that CTA may have false-negative results which can occur if the bleeding is not obvious at the time of the scan due to the short acquisition time (19)(20)(21). Considering that the patient had no indication of active bleeding, and it was difficult to locate the culprit vessel using CTA, we did not perform CTA in this case.…”

Idiopathic Spontaneous Intraperitoneal Hemorrhage Due to Vascular Malformations in the Muscularis of the Stomach: A Case Report

Idiopathic spontaneous intraperitoneal hemorrhage (ISIH) is a phenomenon caused by spontaneous rupture of intra-abdominal visceral vessels, and vascular malformations (VMs) leading to ISIH are rare in previously reported cases. VMs of the gastric wall, which are commonly located in the mucosa and submucosa, mostly lead to upper gastrointestinal bleeding rather than intraperitoneal hemorrhage. To our knowledge, this is the first report of ISIH caused by VMs in gastric muscularis. In the current case, a 22-year-old male patient presented with sudden abdominal pain for 4 h, accompanied by tachycardia and hypotension. CT revealed a hematoma in the omental bursa and fluids in abdominopelvic cavities. Then intraperitoneal hemorrhage was confirmed after abdominal paracentesis. Furthermore, ultrasonic gastroscopy indicated that vascular malformation in the muscularis of the stomach probably led to intraperitoneal hemorrhage. The patient recovered after conservative treatment based on fluid resuscitation and remained stable for 12 months of follow-up. This case suggests that VMs located in the gastrointestinal tract may lead to ISIH and ultrasonic gastroscopy is helpful in the diagnosis of VMs in the gastrointestinal tract.

“…The rate at which DSA detects the cause of bleeding in cases of CTA-negative SAH is 4–8%. [ 1 , 20 ] Although there are few patients with SAH who have negative findings on CTA and positive findings on DSA, it is difficult to distinguish small perforating arteries of less than 1 mm in diameter or to detect very small aneurysms on CTA. [ 3 ] Therefore, even if CTA findings are negative for the cause of SAH, DSA is necessary to investigate the cause of bleeding.…”

Background: The causes of angiogram-negative subarachnoid hemorrhage (SAH) on initial angiography, which accounts for 10–30% of spontaneous SAH, are heterogeneous and still unclear. We report a case of nonaneurysmal SAH, in which initial computed tomographic angiography (CTA) showed no source of bleeding, but the subsequent digital subtraction angiography (DSA) revealed contrast extravasation from the basilar artery without aneurysms. Case Description: A 67-year-old woman with a medical history of hypertension presented as SAH of World Federation of Neurological Surgeons Grade II. CTA on admission did not show any cause of bleeding and DSA was subsequently performed to show contrast extravasation from a perforator of the middle third of the basilar artery without aneurysms during the subsequent DSA, resulting in profound deterioration SAH and neurological status. The patient was conservatively treated. Follow-up DSAs on days 2 and 16 showed no source of bleeding as well. Conclusion: Although the precise cause of bleeding in this case is uncertain, SAH might be caused by local dissection of the basilar artery perforator, and the bleeding site might heal spontaneously without forming of a pseudoaneurysm.

“…It is less time-consuming, cheaper and facilitates scanning patients with pacemakers or other metals. Another feature of CTA is that it provides the best images which show the relationship between aneurysms, vessels, and bone structures [13,14]. CTA was performed first in our patients due to its easiness, cost-effectiveness, and ability to show the relationship with bony structures.…”

Digital Subtraction Angiography for CT Angiogram Negative Haemorrhages

Abstract: In patients with SAH, negative findings on a technically sound CTA are reliable in ruling out aneurysms in any pattern of SAH or no blood on CT. Our observations need to be confirmed with larger prospective studies.
