Treatment of symptomatic pelvic varices by ovarian vein embolization.

PURPOSE: Pelvic congestion syndrome is a common cause of chronic pelvic pain in women and its association with venous congestion has been described in the literature. We evaluated the potential benefits of lumbo-ovarian vein embolization in the treatment of lower abdominal pain in patients presenting with pelvic varicosities. METHODS: Nineteen patients were treated. There were 13 unilateral embolizations, 6 initial bilateral treatments and 5 treated recurrences (a total of 30 procedures). All embolizations were performed with either enbucrilate and/or macrocoils, and there was an average clinical and Doppler duplex follow-up of 15.4 months. RESULTS: The initial technical success rate was 96.7%. There were no immediate or long-term complications. Variable symptomatic relief was observed in 73.7% of cases with complete responses in 57.9%. All 8 patients who had partial or no pain relief complained of dyspareunia. The direct relationship between varices and chronic pelvic pain was difficult to ascertain in a significant number of clinical failures. CONCLUSION: Transcatheter embolization of lumbo-ovarian varices is a safe technique offering symptomatic relief of pelvic pain in the majority of cases. The presence of dyspareunia seemed to be a poor prognostic factor, indicating that other causes of pelvic pain may coexist with pelvic varicosities.

Delayed esophageal hemorrhage caused by a metal stent: treatment with embolization.

We report a case of life-threatening esophageal hemorrhage after metal stent implantation successfully treated by arterial embolization. An 85-year-old woman was admitted in shock secondary to massive hematemesis and melena. Recent medical history revealed esophageal cancer treated 8 weeks previously by endoesophageal radiotherapy (40 Gy) and endoscopic placement of a covered Wall-stent prosthesis. Selective arteriography of the fifth posterior right intercostal artery showed massive contrast extravasation in the esophagus. Embolization was performed with 150-250-micron polyvinyl alcohol particles. Follow-up at 5 months was uneventful. Arteriography and embolization are advised when severe hemorrhage occurs after esophageal implantation of metal stents.

Radiologic damage control: evaluation of a combined CT and angiography suite with a pivoting table.

PURPOSE: To evaluate retrospectively the integrated diagnostic and therapeutic management of severely polytraumatized patients using a combined computed tomography (CT) and angiography suite with a single pivoting table. METHODS: Eleven patients, aged 16-74 years (median 30 years), were managed with spiral CT and angiography without patient transfer. Four patients were unstable, seven had received blood transfusions (2-18 units) and six were intubated. In 10 patients in whom active bleeding was demonstrated (splenic 5, hepatic 2, renal 2, left inferior epigastric artery 1), hemostatic embolization was obtained. RESULTS: Total procedure time did not exceed 80 min. Immediate hemostasis was achieved in all patients. Recurrent bleeding from the liver required additional embolization in one patient. Median length of stay in the intensive care unit was 4 days and median hospital stay was 27 days. All patients survived without significant sequelae. CONCLUSION: The use of a combined CT-angiography suite enables rapid diagnostic investigation and hemostatic embolization in actively bleeding trauma patients.

Pathological aspects of carotid plaques. Surgical and clinical significance.

We examined 134 carotid plaques microscopically in 125 consecutive patients, and found 21 (15.7%) had simple fibrous plaques versus 113 (84.3%) complicated plaques. The following plaque characteristics were present: intraplaque hemorrhage (73 plaques), ulceration (83 plaques), fresh thrombus (93 plaques), and recanalized thrombus (22 plaques). An average of 2.4 characteristics were observed in each complicated plaque. The only significant (p less than 0.05) clinico-pathologic correlation was the presence of fresh thrombi, found in 80% of the plaques from patients with a previous transient ischemic attack, in 93% of those with nonfocal neurologic symptoms, and in 80% of those with amaurosis fugax. Analysing the localization of the fresh thrombus (mural or intraluminal), we found that fresh thrombus in symptomatic plaques was most frequently (NS) (71 to 77%) exposed to the vessel lumen. Ulceration without fresh thrombus, plaque hemorrhage and recanalized thrombus were also found in a considerable number of asymptomatic patients, of whom 85% (33/41) presented a form of complicated plaque.

[Clinical case of the month. Cerebrovascular accident related to arterial brachiocephalic trunk stenosis].

The authors report the case of a 47-year old man, admitted for syncope and left-sided motor deficit. Diagnostic investigations revealed a right middle cerebral artery embolic stroke, secondary to a critical stenosis of the arterial brachiocephalic trunk, harboring a floating thrombus. The treatment options for occlusive lesions of the brachiocephalic trunk are discussed, as well as the optimal delay between stroke and brain revascularization.

Echographic characterization of carotid plaques.

The histology of the endarterectomy specimen was compared with the preoperative echopattern of 154 plaques. Thirty-four ultrasound images were of poor quality. The 120 adequate echographies revealed 22 dense hyperechogenic homogeneous plaques, 28 soft hypoechogenic homogeneous plaques, 53 inhomogeneous plaques, and 13 mixed plaques. According to the surface, lesions were subdivided as smooth (n = 63) or irregular (n = 57). Echography recognized fibrous plaques (dense homogeneous hyperechogeneous lesions), with a specificity of 87% and a sensitivity of 56%. Recent intraplaque haemorrhage is echographically apparent as a hypoechogenic area in 88% of cases, what corresponds to a specificity of 79% and a sensitivity of 75%. Echography proved to be more accurate than angiography in determining the presence or absence of ulceration. The ability to characterize the pathology of carotid atheroma by duplex scan make the clinicopathologic correlation of carotid plaques of practical importance.
