Iatrogenic false aneurysm following repair of intracranial aneurysm.

False aneurysm of the intracranial arteries occurs infrequently as a complication of head injury and rarely as a consequence of other pathology. A case of false aneurysm of the supraclinoid internal carotid artery following minor intraoperative injury during clipping of a basilar-superior cerebellar aneurysm by the pterional approach is described. False aneurysm is a potential cause of recurrent intracranial hemorrhage after successful aneurysm clipping. Arterial bleeding which appears to come from the region of a branch origin should be viewed with concern even if it subsides spontaneously.

Management of splenic artery aneurysms and false aneurysms with endovascular treatment in 12 patients.

PURPOSE: To assess the endovascular treatment of splenic artery aneurysms and false aneurysms. METHODS: Twelve patients (mean age 59 years, range 47-75 years) with splenic artery aneurysm (n = 10) or false aneurysm (n = 2) were treated. The lesion was asymptomatic in 11 patients; hemobilia was observed in one patient. The lesion was juxta-ostial in one case, located on the intermediate segment of the splenic artery in four, near the splenic hilus in six, and affected the whole length of the artery in one patient. In 10 cases, the maximum lesion diameter was greater than 2 cm; in one case 30% growth of an aneurysm 18 mm in diameter had occurred in 6 months; in the last case, two distal aneurysms were associated (17 and 18 mm in diameter). In one case, stent-grafting was attempted; one detachable balloon occlusion was performed; the 10 other patients were treated with coils. RESULTS: Endovascular treatment was possible in 11 patients (92%) (one failure: stenting attempt). In four cases among 11, the initial treatment was not successful (residual perfusion of aneurysm); surgical treatment was carried out in one case, and a second embolization in two. Thus in nine cases (75%) endovascular treatment was successful: complete and persistent exclusion of the aneurysm but with spleen perfusion persisting at the end of follow-up on CT scans (mean 13 months). An early and transient elevation of pancreatic enzymes was observed in four cases. CONCLUSION: Ultrasound and CT have made the diagnosis of splenic artery aneurysm or false aneurysm more frequent. Endovascular treatment, the morbidity of which is low, is effective and spares the spleen.

Left ventricular false aneurysm.

False aneurysms of the left ventricle develop after rupture of the ventricular wall in an area of pericardial adhesions. This complication of myocardial infarction is uncommon. Images of a post-infarction false aneurysm are presented.

Simplified method for compression of femoral false aneurysms.

False aneurysm formation is a not uncommon complication of cardiac catheterization. Until recently, surgical repair was the only therapeutic option available when conservative management failed. However, Doppler-guided compression of the aneurysm has been advocated in recent years; the method requires prolonged indirect manual compression of the femoral artery aneurysm and is uncomfortable for both the patient and operator. In ten consecutive patients the use of Doppler-guided clamp placement and aneurysm compression for 60 min resulted in complete thrombosis of the aneurysm in eight, and only one patient required surgical repair. The procedure was well tolerated by all patients (analgesia was administered liberally). Eight patients were discharged within 24 h, one after 2 days and the single surgical patient remained an inpatient for 6 days. Doppler-guided clamp compression of false aneurysms is a safe, effective and cost effective method of managing these patients.

A gliding space between the femoral artery and inguinal ligament: mechanism of formation of false aneurysm.

False aneurysms preferentially arise in the inguinal region subsequent to aorto-femoral bypass. This finding suggests that the position of the inguinal ligament against the anterior surface of the prosthesis may be an etiological factor. Description of the inguinal region, forming a borderline between the trunk and thigh and specific to the erect posture, has been the subject of many anatomical studies. These papers describe mainly the relations between the vascular sheath of the femoral artery, the fascia transversalis and inguinal ligament. Based on a series of anatomical dissections we have found a gliding space between the femoral artery and inguinal ligament. This finding has led us to propose section of the fibrous portion of the inguinal ligament and the insertion of free omentum between the arch of the ligament and prosthesis in order to prevent false aneurysm. Preliminary results obtained with this technique are satisfactory.

False aneurysm and pseudo-false aneurysm of the left ventricle: etiology, pathology, diagnosis, and operative management.

Four patients are presented in whom either a false aneurysm or a "pseudo-false" aneurysm of the left ventricle developed following a myocardial infarction. False aneurysms of the left ventricle are unusual and are distinctly different from the more common true aneurysms. A false aneurysm is the result of a contained hematoma dissecting, into a transmural infarct. It communicates with the left ventricle through a small orifice. Previous descriptions of false aneurysms have stressed that their wall consists of pericardium and mural thrombus and lack identifiable epicardial or myocardial elements. Two pseudo-false aneurysms are described. They communicated with the left ventricle through a small orifice but their wall contained myocardial tissue. False aneurysms have a tendency to rupture and therefore their presence alone is an indication for operation. One of the pseudo-false aneurysms discussed ruptured into the right ventricle. The operation for false aneurysm may be simpler than that for true aneurysm since it might be possible to close the small communication into the left ventricle without resecting the entire aneurysm wall.

Ventricular aneurysm: false or True? An important distinction.

A case of ventricular false aneurysm withe the typical clinical, radiological, electrocardiographic, and angiographic features of this entity is presented. The distinction between false ventricular aneurysm and true aneurysm is discussed. This distinction is important because of the propensity of false aneurysms to rupture. An early diastolic murmur was present prior to, but not after, resection of the aneurysmal sac. A theory as to the origin of this murmur is offered.

[Aneurysm or false aneurysm of the interauricular septum disclosed by 2 cerebral embolisms].

The authors report a case of solitary aneurysm of the interatrial septum documented by ultrasonography and angiography and revealed by two transient cerebral ischaemic accidents unexplainable by other causes. At surgery, performed later, the interatrial septum was redundant, and Botallo's foramen was about 17 millimetres in diameter, but no sacciform cavity was found. The reasons for the discrepancy between imaging techniques and operative findings and the mechanism of systemic embolism are discussed.

Results of the repair of aortic false aneurysm.

Aortic false aneurysm is a rare complication of surgery of the aorta that can occur several months to years after the initial operation. We reviewed our results with false aneurysm repair using deep hypothermia and circulatory arrest. Three patients were reoperated for false aneurysm of the ascending aorta. Femorofemoral cardiopulmonary bypass with a heparinized system was used in all patients. Hypothermic circulatory arrest at an average temperature of 20 degrees C was instituted in all patients for repair. Two patients had a patch repair with pericardium, and the other one had primary repair of the defect. All patients had false aneurysms in the ascending aorta at the site of a previous aortotomy. Two patients had proven infection as the cause. The mean cardiopulmonary bypass time was 183 +/- 20 minutes, and the mean circulatory arrest time was 35 minutes. Operative mortality was not seen. The mean time for extubation in survivors was 10 - 12 hours, and the average time to discharge was 26 days. Aortic false aneurysms can be safely approached using femorofemoral cardiopulmonary bypass, hypothermic circulatory arrest, and patch repair with acceptable operative mortality and long-term survival.

Post-traumatic left ventricular false aneurysm.

Most false aneurysms of the heart represent contained ventricular free wall ruptures after myocardial infarction. Post-traumatic aneurysms also may follow penetrating or non-penetrating trauma to the chest. Regardless of the origin of the false aneurysm there is a propensity for aneurysm rupture. We report a patient who developed a false aneurysm of her left ventricle that developed post-motor vehicle accident. Her orthopedic problems were the clinical problems identified and after a hospital admission of 10 days she was discharged home. Four weeks later she died suddenly from anterior left ventricle false aneurysm rupture and tamponaide. Patients with significant chest wall trauma should be assessed for cardiac pathology prior to discharge. Presentation may be delayed and be overshadowed by more evident pathology. Trauma-related aneurysms may cause sudden death, and this may occur some later time after the trauma. Attributing the cause of death to the trauma, which may be remote, is important for the forensic investigator to remember.

Prolene sutures are not a significant factor in anastomotic false aneurysms.

Anastomotic false aneurysms have been a significant complication in vascular surgery, and the sutures used have been a major cause. Monofilament sutures have been indicated as contributing to the formation of false aneurysm. However, most of the monofilament sutures operative in the formation of false aneurysms have been made of polyethylene. Polypropylene, although significantly different from polyethylene, has been associated and possibly confused with it. Very few anastomotic aneurysms have resulted from breakage of polypropylene sutures. In this series of 2,400 vascular anastomoses in which polypropylene sutures were used, there were 10 false aneurysms; however, only one resulted from suture failure. In that patient, two Dacron grafts were anastomosed with 5-0 polypropylene suture. Polypropylene is a satisfactory and safe suture material for vascular anastomoses. It does not fragment or break easily when properly handled, and therefore is not a principal cause of false aneurysms.

[Stenting of the right subclavian artery posttraumatic false aneurysm].

Posttraumatic false aneUrysms can be life threatening and often their management might be a challenge, because of poor general condition as well as because of specific technical difficulties. Open surgery requires wide exposure and dissection of posttraumatic tissues. Endovascular techniques using stent-grafts gains popularity because of high efficiency, safety and good results. We present a case of posttraumatic false aneurysm of right subclavian artery treated with a stent-graft.

[Non-surgical therapy of iatrogenic false aneurysms].

SUMMARY: False aneurysms occur after 0.1 - 1.5 % of all diagnostic and up to 6 % of all therapeutic percutaneous interventions. Surgery used to be the treatment of choice in symptomatic patients. But two non-invasive measures of treatment gain more attention: ultrasound guided compression (UGC) and ultrasound guided thrombin injection (UGTI). UGC with compression times from 30 - 120 min is effective in 80 % of patients without anticoagulation. However, UGC is often painful and results in prolongation of in-hospital time. UGTI is effective in 95 % of patients. Usually, 100 - 2000 U of thrombin are injected into the false aneurysm. UGTI is also effective in the presence of anticoagulation or antiplatelet therapy. UGTI is not indicated in patients with a large communication with the native vessel and in arterio-venous-fistulas. In patients with large haematomas, ongoing bleeding, damage of the native vessel, compression of arteries, veins or neurological deficits, or with infections, early surgical repair is still the treatment of choice.

Obstruction of the ureter due to a false aneurysm.

A false aneurysm arising from an aortofemoral bifurcation graft caused symptomatic ureteral obstruction in a 69-year-old woman. Following revision of the aortograft anastomosis, her symptoms and ureteral obstruction subsided. The prevention and treatment of ureteral complications following vascular surgery are discussed. Postoperative pyelograms may be indicated in the vascular bypass patient.

Endovascular repair of aortic aneurysms, arteriovenous fistulas, and false aneurysms.

Between September 1990 and June 1995, 103 patients were treated with transluminal placed endovascular grafts: 87 had abdominal aortic aneurysms (AAA), two had iliac artery aneurysms (one in association with an AAA), 3 had thoracic aneurysms, and 12 had vascular injuries in various localization of the arterial tree. The AAAs were excluded from the blood flow with a device composed of a balloon-expandable stent (modification of the Palmaz stent) attached to a Dacron graft designed to expand at both ends of the accompanying stent extension. An 18F sheath containing the stent-graft device was introduced through a small cut-down in the common femoral arteries and advanced under fluoroscopic guidance. Color duplex, contrast-enhanced computed tomography (CT) scanning and angiography were performed before the procedure and then every 6 months. (Arteriography was performed once during the follow-up period and whenever other studies disclosed an abnormal finding.) A total of 87 patients (75 men, 12 women) harboring an AAA were treated: Forty-five patients underwent an aortoaortic procedure (8 patients had only a proximal stent implanted, and 37 had proximal and distal stents). Forty-two patients were treated by implanting an aortoiliac graft, completing the procedure with a femorofemoral bypass. The contralateral common iliac artery was occluded by means of an occluding stent. One type A dissecting aneurysm and two descending thoracic aneurysms were successfully treated by the endovascular technique. The longest follow-up period was 60 months and the shortest 1 month. Initial success was obtained in 84% of the aortoaortic cases and in 75% of the aortoiliac procedures. Long-term follow-up (> 12 months) disclosed 78% success for the aortoaortic cases and 90% for the aortoiliac procedures. Late failures included distal aortic dilatation, distal leak into the aneurysmal cavity, and proximal leak into the aneurysm. All trauma cases were successful over the short and long terms. Trauma cases included false aneurysms (common carotid, subclavian, common femoral arteries) and arteriovenous fistulas (subclavian, aortocava, common iliac-cava and superficial femoral artery and vein). We concluded that stent-graft combination devices appear to be an alternative for treating vascular trauma and aneurysms. Initial success for treating AAAs is almost 100%, and late success in aortoiliac cases is also high (90%) for aortoaortic reconstruction. However, late failures are frequent and require further evaluation in relation to a persistent increase in the diameter of the proximal neck and distal cuff.
