Successful stent-graft placement for the treatment of a superior gluteal artery pseudoaneurysm in a patient following complex pelvic surgery

Aneurysms of the gluteal arteries are rare and were previously managed with open surgical procedures. Recently percutaneous embolisation techniques have helped reduce morbidity and mortality. A case is presented of a 63-year-old man who presented with haemorrhage and had developed a superior gluteal artery aneurysm following treatment for an invasive squamous cell carcinoma in the sacral area. There was concern that embolisation of the aneurysm might compromise the survival of the myocutaneous buttock rotation flaps that had been used for reconstruction. To overcome this, an endovascular stent was deployed to successfully close off the aneurysm whilst at the same time maintaining blood flow through the superior gluteal artery. Aneurysms in larger peripheral vessels have been managed with stents. However, this is the first reported case of this method of treatment being used in the management of gluteal artery aneurysms.

Successful transcatheter arterial embolization for pseudoaneurysm of the deep femoral artery in a patient with presumptive ACTA2-related vasculopathy

ACTA2-related vasculopathy is an autosomal dominant genetic disorder characterized by aortic aneurysms and dissection, and limb artery lesions are rare. We report a case of transcatheter arterial embolization for a pseudoaneurysm of a deep femoral artery in a patient with presumptive ACTA2-related vasculopathy. A 58-year-old woman was presumed to have an ACTA2 mutation based on her history of aortic diseases and family history of ACTA2 mutations. During follow-up, contrast-enhanced computed tomography for aortic diseases revealed occlusion and vessel wall abnormalities of the bilateral deep femoral arteries. Two weeks later, she complained of acute right inguinal pain without any triggering factors, and contrast-enhanced computed tomography revealed a pseudoaneurysm of the right deep femoral artery. Vascular fragility due to ACTA2 mutation was believed to be the cause of the pseudoaneurysm. Transcatheter arterial embolization was successfully performed and no rebleeding occurred during 1.5 years after the transcatheter arterial embolization.     

Successful closure of large pseudoaneurysm of peroneal artery using transluminal temporary occlusion of the neck with the catheter

Pseudoaneurysm is well-known complication resulting from surgical or interventional vascular procedures. We present the case of a 51-year-old patient with a large iatrogenic pseudoaneurysm of the peroneal artery, a very rare location. The pseudoaneurysm developed after orthopedic surgery of the knee. Swelling and vascular insufficiency of the calf ensued a few days later. The large peroneal pseudoaneurysm and compression of the anterior and posterior tibial arteries were confirmed by ultrasound and angiography. The pseudoaneurysm was too deep for ultrasound-guided compression or percutaneous obliteration and too large to be occluded by coil embolization alone. Because the pseudoaneurysm failed to occlude even after four coils were introduced into the lumen, pseudoaneurysm thrombosis was achieved by temporary occlusion of its neck with the angiographic catheter. During the occlusion of the neck of the pseudoaneurysm, the patency of the crural arteries and the development of the thrombus in the pseudoaneurysm cavity were monitored with color Doppler ultrasonography. Follow-up examinations after 3 and 6 months showed permanent closure of the pseudoaneurysm and patent crural arteries.     

Pseudoaneurysm of the superior gluteal artery following polytrauma

Gluteal artery aneurysms are rare and often secondary to pelvic fractures, blunt or penetrating trauma. We describe a case of a superior gluteal artery pseudoaneurysm that presented as back pain with numbness and weakness of the lower extremities. Diagnosis was confirmed by color Doppler sonography and angiography. A proximal and distal control was obtained over the aneurysm neck via coil embolization with excellent hemostasis within the pseudoaneurysm and maintenance of perfusion to the left pelvis.     

Transcatheter embolization of a superior mesenteric artery pseudoaneurysm. A case report

A 61-year-old man, with pseudoaneurysm of the superior mesenteric artery presenting with gastrointestinal bleeding, was successfully treated by transcatheter embolization using interlocking detachable coils. During the following observation time of 10 months, the patient had no sign of gastrointestinal bleeding. We underline the importance and feasibility of transcatheter embolization as the first-line treatment in such pseudoaneurysms.

Successful treatment of a pseudoaneurysm of the cystic artery with microcoil embolization.

Pseudoaneurysms of visceral arteries are uncommon but well-characterized vascular abnormalities, usually provoked by intraabdominal inflammatory processes such as pancreatitis or cholecystitis, or by surgical trauma. However, pseudoaneurysms of the cystic artery are rare. They complicate cholecystitis or cholecystectomy, and manifest as hemobilia as they rupture into the biliary tree. The advent of transcatheter embolization techniques has begun to allow minimally invasive treatment of these life-threatening complications. Transcatheter embolization can be performed using several types of material, such as synthetic occlusive emulsions, gelatin sponges or other particles, or metallic microcoils. Microcoils are small metallic helical particles, made of stainless-steel, platinum, or tungsten. Super-selective catheterization of an artery and release of microcoils causes the vessel to thrombose and allows control of bleeding.     

Spontaneous healing of cervical pseudoaneurysm in vertebral artery dissection under anticoagulant therapy

We report a 41-year-old woman with embolic stroke of the mid-pons attributed to embolism from vertebral artery dissection. Angiography revealed an occluded artery on one side and an incidental pseudoaneurysm of the midcervical portion of the vertebral artery on the other. After 3 months of warfarin therapy control angiography showed complete occlusion of the pseudoaneurysm. We discuss therapeutic choices and review the literature.

Retained contrast after embolization of a right gastric artery pseudoaneurysm

Pseudoaneurysms due to chronic pancreatitis can be a source of major gastrointestinal (GI) hemorrhage. Computed tomography (CT) is the primary diagnostic imaging modality for pancreatic pseudocysts associated with GI bleeding can be diagnosed and embolized with transcatheter techniques once the arterial anatomy is defined. CT is a useful modality for follow-up examination of the pseudocyst; the findings must be correlated with other procedures performed on these patients. On follow-up studies, contrast medium retained in the pseudocyst after embolization may falsely signal persistent bleeding into the pseudocyts.     

Transcatheter embolization of the marginal artery of drummond as treatment for life-threatening retroperitoneal hemorrhage complicating heparin therapy

We report a case in which life threatening retroperitoneal hemorrhage complicated heparin therapy. The bleeding originated from the marginal artery of Drummond which was catheterized with a 3 Fr coaxial catheter system (Tracker 18 catheter) and embolized with microcoils. Bleeding stopped and no ischemic complications developed for 3 years after embolization.

Glue embolization of a ruptured celiac trunk pseudoaneurysm via the gastroduodenal artery

Percutaneous transcatheter embolization of splanchnic artery aneurysms is a minimally invasive and alternative therapy to conventional surgical intervention. Due to a high-grade stenosis at the origin of the celiac trunk, a retrograde approach to the celiac trunk pseudoaneurysm via the gastroduodenal artery was necessary. To prevent undesirable embolization into the peripheral left gastric artery initial occlusion of the central portion of the left gastric artery was performed with microcoils using a Tracker catheter. Complete occlusion of the celiac trunk itself and the short adjacent segments of the celiac artery was achieved by using a mixture of N-butyl-2-cyanoacrylate and ethiodized oil as the embolizing agent.

Successful embolization of a renal artery pseudoaneurysm with arteriovenous fistula and extravasations using Onyx after partial nephrectomy for renal cell carcinoma

Partial nephrectomy can be associated with vascular complications. Computed tomography (CT) with CT angiography is ideal for noninvasive imaging of this process. The treatment of choice is selective embolization. Successful transcatheter embolization of right renal subsegmental artery pseudoaneurysm with arteriovenous fistula and extravasations using Onyx was performed in a 66-year-old woman with macrohematuria 12 days after partial nephrectomy for renal cell carcinoma.
