Traumatic Pseudoaneurysm of the Superficial Palmar Arch: A Case Report and Review of the Literature

Post-Traumatic Retroperitoneal Hematoma Caused by Superior Rectal Artery Pseudoaneurysm

“…Inadvertently-discovered occurrences have been reported in the peripheral arteries as a known complication of percutaneous interventions, but there are other unique locations and occurrences that have occurred without interventions, similar to our case. Some of these other rare cases included involvement of the middle meningeal artery, superior mesenteric artery, occipital artery, and palmar arch [ 10 – 14 ]. Such as the cases referenced in our SRA pseudoaneurysm review, these patients presented with varying symptoms, mechanisms, time to diagnosis, and treatment modalities.…”

“…Such as the cases referenced in our SRA pseudoaneurysm review, these patients presented with varying symptoms, mechanisms, time to diagnosis, and treatment modalities. Their presenting symptoms were most commonly related to pseudoaneurysm location, and included drowsiness, headache, aphasia, pain, recurrent bleeding, and swelling [ 10 – 14 ]. The mechanisms also differed, with both traumatic and nontraumatic causes (acute head trauma, chronic development after head trauma, apixaban use, knife laceration) [ 10 – 14 ].…”

“…Their presenting symptoms were most commonly related to pseudoaneurysm location, and included drowsiness, headache, aphasia, pain, recurrent bleeding, and swelling [ 10 – 14 ]. The mechanisms also differed, with both traumatic and nontraumatic causes (acute head trauma, chronic development after head trauma, apixaban use, knife laceration) [ 10 – 14 ]. Similarly, treatment and time to treatment varied between endovascular and open approaches – immediate and months after initial injury, respectively.…”

“…Similarly, treatment and time to treatment varied between endovascular and open approaches – immediate and months after initial injury, respectively. These treatments included cerebral angiogram with Histoacryl embolization of the middle meningeal artery, cerebral angiogram with glue embolization of middle meningeal artery, endovascular coiling, and open surgical ligation [ 10 – 14 ] ( Table 1 ). Consistent with our SRA pseudoaneurysm review, the mechanism, presentation, timing, and management of these pseudoaneurysms varied, but all reported cases required appropriate identification and treatment to prevent further serious complications, bleeding, rupture, and death.…”

“… Summary of documented case details to aid in comparison of cases and results, including presenting symptom, mechanism, treatment modality, and time to treatment [ 2 – 8 , 10 – 14 ]. SRA – superior rectal artery; GI – gastrointestinal, PTD – post-trauma day; MMA – middle meningeal artery.…”
