“…Reports of pseudoaneurysms after craniotomy are rare, with only 16 cases in the literature (►Table 1). [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16] Reported causes of STA damage include subcutaneous suture needles, hook retractor, or three-point pin fixators. [6][7][8]13,16 Systemic diseases including hemophilia or vasculitis, and background such as triple H therapy after subarachnoid hemorrhage, are also risk factors for pseudoaneurysms.…”

“…Thus, the pseudoaneurysm in present case may have resulted from microtrauma to the intima caused by surgical manipulation or electrocautery. 1,3 Alternatively, the STA may have been injured during subcutaneous closure, resulting in a small unnoticed bleed that caused the pseudoaneurysm. 1,5,8,13 The risk factors and probability of pseudoaneurysm rupture are unknown.…”

“…A superficial temporal artery (STA) pseudoaneurysm after a craniotomy is rare, with only 16 cases reported in the literature -the majority of these were found in subcutaneous pulsatile and painless masses. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16] Herein, we report a case of an STA pseudoaneurysm with severe subcutaneous bleeding after craniotomy, and provide a review of the literature. To our knowledge, only three similar cases have been reported.…”

We present a case of a ruptured pseudoaneurysm of the superficial temporal artery (STA) after surgery for intracranial hemorrhage. To our knowledge, only three similar cases have been reported. A 47-year-old man underwent left frontal craniotomy for a left frontal subcortical hematoma. The left STA was not identified during the surgery, and no STA bleeding was observed. The postoperative course was uneventful for 20 days, until the patient experienced a left-side headache and noticed a subcutaneous mass. The mass increase in size within 1 hour and arterial hemorrhage was observed through a tear in the wound. Findings on subsequent contrast computed tomography were consistent with a ruptured pseudoaneurysm arising from the left STA. Emergency evacuation of the hematoma and STA ligation were performed. Pathological findings were consistent with a pseudoaneurysm. STA pseudoaneurysms occasionally grow rapidly and can cause massive hematoma. Surgeons should carefully monitor for evidence of a pseudoaneurysm after craniotomy, even in the absence of intraoperative bleeding from the STA.

“…Along with covered stents, there are several options for endovascular repair. Embolism with coils or liquid embolic agents, gelfoam, or vascular plugs have all been successfully used [8]. These options work well for most pseudoaneurysms, even in infected fields.…”

Introduction. Anastomotic pseudoaneurysms are a complication of vascular reconstructive surgery with the majority in the femoral region. Although rare, ruptured femoral anastomotic pseudoaneurysms have high mortality and require emergency surgery. Case Presentation. A 60-year-old male with a history of a left leg crush injury was treated with a superficial femoral artery interposition vein graft 30 years ago. He presented nowadays with a three-day history of severe pain in his left thigh. CT angiography demonstrated a ruptured anastomotic pseudoaneurysm with contrast extravasation into an intramuscular hematoma. He had significant scarring from his previous surgeries which made the leg hostile for an open repair. Therefore, percutaneous access selectively cannulated the left iliofemoral vasculature. An angiogram showed a distal superficial femoral artery pseudoaneurysm. Subsequently, two 10mmx15cm Viabahn covered stents (Gore & Associates, Flagstaff, AZ) were placed bridging healthy superficial femoral artery. A completion angiogram demonstrated no extravasation into the pseudoaneurysm. The patient recovered and was discharged home two days postoperatively. Conclusion. Ruptured femoral anastomotic pseudoaneurysms are traditionally repaired with open pseudoaneurysm excision and arterial reconstruction, although endovascular repair has been reported. Furthermore, most femoral anastomotic pseudoaneurysms form less than 10 years after initial operation. We present a unique case of ruptured superficial femoral artery pseudoaneurysm, 30 years after the initial operation. Endovascular stents offer effective treatment for ruptured anastomotic pseudoaneurysms.
