Pseudoaneurysm of the popliteal artery caused by exostosis of the femur: case report and review of the literature.

A 13-year-old boy with a solitary exostosis of the left femur was seen with a pseudo-aneurysm of the popliteal artery. When left leg pain occurred 3 months earlier, radiographic examination revealed an exostosis with a cartilage cap. Serial radiographic examination demonstrated gradual disruption of the cartilage cap of the exostosis as the pseudoaneurysm developed. An exostosis with an irregular surface was found at surgery. A literature review disclosed 39 similar cases in which loss of the cartilage cap was considered as one of the causes of the aneurysm formation. Considering the clinical course of our patient, however, we believe that exostoses lose their cartilage caps by pressure destruction due to the aneurysms. It is highly probable that loss of the cartilage does not cause the aneurysms.

A case of cystic adventitial disease of the popliteal artery demonstrated by magnetic resonance imaging.

In a 45-year-old man, who was free of symptoms after a 3 1/2-month period of calf claudication, a diagnosis of cystic adventitial disease was confirmed by magnetic resonance imaging. At operation a 12 cm long intramural cyst of the popliteal artery, continuous with a cyst around a genicular arterial branch, was found. Total resection of the cyst and its branch was performed. We recommend computed tomography or magnetic resonance imaging as the diagnostic tools of first choice in young patients who are free of arteriosclerosis and who have episodes of intermittent claudication of the calf.

Popliteal artery reconstruction secondary to minor trauma in a 19-year-old morbidly obese woman.

Obesity is an increasing burden on health-care globally. Significant obesity is presenting at a younger age, with pathology that has not been previously seen. This case report illustrates the catastrophic consequences which may occur when minor trauma occurs in a young person who suffers from morbid obesity. A 19-year-old woman with BMI 50 tripped over an uneven curb, and suffered complete dislocation of the knee with associated popliteal artery injury. She required femoro-popliteal bypass using vein. This case reports the youngest person to suffer from this injury and the first in the UK.

[Cystic adventitial degeneration of the popliteal artery: an unusual cause of intermittent claudication].

The case is reported of a 44-year-old patient without cardiovascular risk factors who complained of typical intermittent claudication. Arteriography and echography led to the diagnosis of cystic adventitial disease of the popliteal artery. Percutaneous puncture under CT control was unsuccessful and surgical resection of the cystic formation was performed. This rare etiology is discussed in relation to the differential diagnosis of intermittent claudication, with particular reference to young patients.

[Injury of the popliteal artery as a complication of knee dislocation].

Dislocation of the knee is rarely seen. Only 15 patients with a knee dislocation were treated in the surgical department of the university hospital in the last 18 years. One patient had bilateral dislocation of the knee. Injury to the popliteal artery is severe and often endangers the extremity. In seven patients with knee dislocation arterial ischemic was detected. Five patients were treated for arterial damage (31.25%).

Popliteal artery stenting using flexible tantalum stents.

PURPOSE: To evaluate the safety and efficacy of stent therapy for the treatment of residual stenoses after percutaneous transluminal angioplasty (PTA) of popliteal stenoses and occlusions. METHODS: In a prospective single-center study, flexible tantalum stents were implanted in 32 popliteal arteries for the treatment of residual stenosis greater than 50% after PTA of stenoses (n = 17) or occlusions (n = 15) in the P1 (n = 16), the P2 (n = 13), or both P1 and P2 segment (n = 3). Follow-up patency was assessed by clinical examination, ankle-brachial index, and color Doppler sonography or angiography. RESULTS: Early stent thrombosis (10 days): 1 of 32 arteries (3%). 1-year and 2-year primary patency rate (PPR): 81% +/- 7.1% and 74% +/- 9.1%, respectively. 1-year PPRs for subgroups: stented stenoses versus stented occlusions: 88% +/- 7.8% vs 73% +/- 12.0%, p = 0.12; good lower limb runoff versus poor: 84.0% +/- 8.7% vs 76.0% +/- 12.4; p = 0.09; P1 versus P2: 77.3% +/- 9.8% vs 85.7% +/- 9.4%, p = 0.38. Recurrent PTA lesions treated with stents showed higher restenosis rate than de novo lesions. CONCLUSION: The results of stent therapy of residual popliteal stenosis after PTA are encouraging and warrant further investigation.

[Cystic degeneration of the adventitia of the popliteal artery--case report].

Cystic adventitial disease (CAD) is a rare diagnosis with a higher number of the patients in recent years. The article gives a brief of the pathology and etiolopathogenesis of adventitial cystic disease and two case reports of the patients with CAD of the popliteal artery treated in our department between 1997 and 2001. Successful results are achieved only with surgical treatment.

Popliteal artery injury complicating arthroscopic meniscectomy.

We describe two patients who sustained serious vascular complications following arthroscopic lateral meniscectomy. Such injuries are rarely encountered or reported in the literature and, as such, the potential catastrophic sequelae of this particular complication of arthroscopy may be underestimated. Investigation of suspected popliteal artery injuries is outlined and the need for a high index of suspicion and early referral to a vascular surgeon is stressed.

Popliteal artery thrombosis in a patient with Cogan syndrome: treatment with thrombolysis and percutaneous transluminal angioplasty.

A 31-year-old woman with Cogan syndrome (a rare form of systemic vasculitis) was evaluated for a cold, painful left foot with diminished pulses. Arteriography demonstrated thrombosis of the left popliteal artery with evidence of vasculitis. Thrombolytic therapy was begun with initial success but eventual rethrombosis. After reinitiating thrombolytic therapy combined with intraarterial vasodilator therapy, successful angioplasty was performed with sustained results at 6-month follow-up.

Popliteal artery bullet embolism in a case of homicide: a case report and review of the tangible literature.

Bullet embolism is a well known but a relatively rare phenomenon in common medicolegal autopsy practice. We present a homicide case of a bullet embolism to the left popliteal artery with interesting trajectory of projectile through the chest wall and right heart ventricle into the aortic lumen. Since in our presented case obvious homicidal manner of death was in question, discovery of bullet was an obligatory part of investigation in order to positively identify the responsible firearm. Detection of the missile transported through the circulation requires very thorough autopsy examination, especially if X-ray equipment is not available. As in all other cases in which initial bullet trajectory is changed in the body, the very important part of the medicolegal autopsy in cases accompanied with missile embolism, is to determine direction of the first part of the bullet's trajectory, because this indicates the position of the axis of the weapon barrel in the moment of firing (if there was no external ricochet), taking into consideration the posture of the victim and the location of the shooting person in the same moment. A review of the tangible literature is given.

Occult popliteal artery stenosis masquerading as atheroemboli in a patient with previous knee replacement.

The purpose of this article is to report the unusual presentation of a 63-year-old patient with Rutherford grade 2, category 5 tissue ischemic changes involving the right foot secondary to an occult popliteal stenosis that was obscured behind a prosthetic knee on diagnostic angiograms. Conventional abdominal angiography with bilateral lower extremity runoff showed no evidence of significant disease and the patient was misdiagnosed with atheroemboli syndrome secondary to ipsilateral common femoral access following recent catheterization. Ultimately, a meticulous physical examination disclosed a bruit in the right popliteal fossa and selective right leg angiography with oblique views confirmed eccentric complex luminal encroachment in the right popliteal artery that was eclipsed by a prosthetic knee on antecedent nonselective angiography. The lesion responded favorably to endovascular treatment with durable clinical improvement. This case illustrates the importance of a meticulous physical examination and noninvasive studies prior to angiography in patients with ischemic tissue changes and emphasizes the importance of oblique views to image any vessel that may be obscured by a metal prosthesis.

Popliteal artery entrapment: MR findings.

A 35-year-old woman with a history of claudication was examined by means of echodoppler, angiography, and MR imaging using gradient rephased sequences, performed at rest and during stress. Magnetic resonance imaging allowed the evaluation of the relationships between the gastrocnemius muscle and the popliteal artery at rest and the evidence of the occlusion during stress. This combined morphological and functional evaluation makes MR a procedure of choice for assessment of young adults with intermittent claudication.

Adventitial cystic disease of the popliteal artery: percutaneous US-guided aspiration.

PURPOSE: To evaluate percutaneous ultrasound (US)-guided aspiration as an alternative therapy for adventitial cystic disease. MATERIALS AND METHODS: Between September 1993 and June 1996, seven patients (six men, one woman; age range, 42-62 years; mean age, 48 years) presented with symptomatic adventitial cystic disease of the popliteal artery (one patient with subacute foot paresthesia, six patients with chronic calf claudication). Color Doppler sonography showed stenosis due to eccentric cysts. Five of the patients also underwent digital subtraction angiography, and four patients underwent magnetic resonance imaging. With real-time sonographic guidance, a 14-gauge needle was forwarded percutaneously into the cysts for aspiration. The aspiration procedure was performed on an outpatient basis with local anesthetics. RESULTS: The procedure was technically and clinically successful in all cases. No complications were noted. Follow-up color duplex sonography performed between 1 and 32 months (mean, 14.8 months) after the procedure showed no relevant recurrent stenosis. CONCLUSION: Percutaneous US-guided aspiration is an easy, safe, efficacious method for treating adventitial cystic disease. In symptomatic patients who do not have thrombotic occlusion, it may be considered the treatment of choice.

Value of high resistance index - HRI calculated from Doppler spectrum of popliteal arteries in patients with systemic lupus erythematosus (SLE).

BACKGROUND: HRI is a new Doppler index calculated as a ratio between S -maximal systolic flow and D -maximal early diastolic reversed flow -HRI=D/S. The aim of the study is to evaluate the diagnostic significance of HRI calculated from the Doppler spectrum of popliteal arteries in patients with systemic lupus erythematosus (SLE) with and without secondary antiphospholipid syndrome (SAPS) compared with healthy controls. MATERIAL/METHODS: During 9-month period (May 2003 -January 2004), 93 patients (81 women and 12 men) with SLE (including 24 patients with SAPS) and 30 healthy controls (24 women and 6 men) underwent bilateral duplex Doppler examinations of lower limb arteries. The examinations were performed using HDI 3500 (ATL) with 5 -12 MHz linear transducer under standardized conditions: correct insonation angle and sample volume size, with the patient in a supine position, after 10 minutes rest. RESULTS: Mean HRI value obtained in the control group was 0.415 (range 0.305 -0.555; median 0.402). In the group of SLE patients without SAPS, mean HRI value was decreased to 0.320 (range 0 -0.584; median 0.334) and even lower -0.283 in SLE patients with SAPS (range 0.106 -0.545; median 0.291). CONCLUSIONS: Small arteries, arterioles and capillaries are the main affected vessels in SLE. This chronic process stimulates circulation through lower resistance collaterals, decreasing HRI value. The Doppler HRI calculation can be valuable in early diagnosis and monitoring of lower extremity vascular changes in patients suffering from SLE with and without SAPS.
