Successful management of popliteal arterial disruption in Ehlers-Danlos syndrome.

A review of the literature on Ehlers-Danlos syndrome with particular attention to vascular complications enabled us to outline an orderly diagnostic and therapeutic plan which has allowed salvage of an individual with a popliteal false aneurysm. In patients with Ehlers-Danlos syndrome and brachial, superficial femoral, or popliteal arterial disruption, the use of proximal tourniquet control to allow ligation of the disrupted artery under a no-flow, no-pressure situation is recommended. The ligations should be carried out with a large ligature or possibly with large hemoclips and/or reinforced with multiple fine atraumatic vascular sutures distally. These patients may be treated successfully for flexion contractures because of the laxness of their tissues.

Endartery stenosis of the popliteal artery mimicking gastrocnemius strain: a case report.

This report presents a case of leg pain in a recreational athlete that was caused by a stenotic lesion of an endartery branch of the popliteal artery. Isolated areas of arterial stenosis are rarely reported in the sports medicine literature as the primary cause of leg pain. This may be due in part to the difficulty of obtaining the diagnosis. This study includes a review of the relevant anatomic, pathophysiologic, diagnostic, and therapeutic considerations and concludes with a discussion of the potentially underrecognized significance of arterial stenosis in the sports population.

[A comprehensive approach to the treatment of popliteal artery aneurysms--personal experience].

UNLABELLED: During a five-year retrospective follow-up period the authors treated a group of 46 patients with the diagnosis of aneurysm of the popliteal artery (AAP). The group comprised 42 men (91%) and 4 women (9%). The mean age was 62 years. In 32 patients (69%) AAP was on both lower extremities, in the remaining 14 (31%) it was unilateral. Forty-one patients (90%) had surgery and a total of 48 AAP were operated. The remainder was treated by conservative methods (10%). The first symptoms of AAP in the investigated group were: claudication in 17%, thromboembolic complications in 46%, rupture of the AAP in 4%. An asymptomatic aneurysm was detected in 33%. RESULTS: The authors did not record any death or occlusion of the reconstruction during hospitalization. When using a vein the primary patency is 100%. When a prosthesis (PTFE) is used the results are worse but still satisfactory and the five-year secondary patency is 85%. Five patients with thromboembolic complications of AAP were successfully treated by i.a. fibrinolysis. In all exclusion of the aneurysm and revascularization of the extremity followed. In the conclusion the authors emphasize the necessity of early surgical treatment as soon as the condition is detected, before the development of thromboembolic complications of AAP. If they develop it is essential to attempt local fibrinolysis and in the second stage revascularization of the extremity, if possible by a vein.

[Entrapped popliteal artery. Value of medical imaging and review of the literature].

Medical imaging techniques (Duplex-scan, arteriography, CT scan, magnetic resonance) are obviously the most important elements in the diagnosis and prognostic evaluation in cases of "entrapped" popliteal artery. The physiopathogenic mechanism of this arteriopathy is a localized microtrauma of the arterial wall due to vascular compression by pre-existing anatomic abnormalities of the popliteal fossa.

An unusual presentation of simultaneous bilateral popliteal artery embolism--a case report.

We present what we believe is the first case in the literature of carcinoma of the lung presenting de novo as an intracardiac mass with bilateral, simultaneous popliteal artery embolization. Arterial thromboembolism of cardiac origin and in situ thrombosis of a preexisting atherosclerotic lesion or aneurysm account for the majority of cases of acute lower extremity ischemia. Less common causes include trauma, aortic dissection, venous ischemia, and foreign body or tissue embolization. Although the history, physical examination, and electrocardiographic findings may provide a likely explanation in many cases, noninvasive studies such as echocardiography may help further elucidate the embolic source.

Bypass grafting to the popliteal artery in limbs with occluded crural arteries.

Intraoperative completion angiograms of 47 femoropopliteal bypasses in limbs with occluded crural arteries were reviewed to identify the angiographic determinants of early outcome. Of 28 limbs in which the foot vessels were available for analysis, only 2 (7%) had an intact pedal circulation, and 18 limbs demonstrated no crural arteries suitable for distal reconstruction. The overall cumulative patency rate was 51% with a 76% limb salvage rate at 12 months. All seven grafts performed onto a popliteal artery segment of less than 8 cm occluded in the early period. The status of crural and foot arteries and the number of collaterals did not correlate well with early patency. Limbs with no patent crural artery that were analyzed in the poor angiographic runoff group, according to our previously reported classification, demonstrated relatively higher patency rates than the other subgroups with poor runoff. In cases where angiography demonstrates a poor runoff for distal revascularization, popliteal bypass with occluded crural arteries might achieve acceptable patency rates.

The management of aneurysms and arterio-venous fistulae of the popliteal artery arising from war trauma. Emphasis on sigmoid operative approach.

Between 1986-1988, 600 vascular cases arising from the Iran-Iraq conflict were dealt with within an 18 month period and 60 cases of popliteal artery and/or venous disruption were encountered presenting at variable times after injury. A policy of management between the forward and base hospital surgical teams was introduced, observing the following broad categorizations: (a) assessment/referral, (b) assessment/fasciotomy/referral, (c) immediate operation/referral for further operation/review/management. Two types of incision were used to enter the popliteal fossa: (a) a medial incision and (b) a sigmoid posterior incision (which we now favor). The results of this strategy of management and operative technique (when compared with our previous experience within the same time frame) suggested an improved outcome. Fifty-four out of 60 cases had a satisfactory operative result with below-knee amputation being required in only four cases and higher amputations in two others. No operative or postoperative deaths occurred. The implementation of this "vetting policy" at the front line appeared to reduce the number of amputations and assisted the clarification of management criteria in assessing limb viability at the forward hospital when a large number of casualties were being received. Operative access using the sigmoid posterior incision was not associated with any complications, offered better exposure than the medial incision and was technically easier for the surgeon to perform.

Preliminary experience with expanded polytetrafluoroethylene grafts inserted for chronic occlusive disease of the femoro-popliteal artery segment.

In a prospective study the early clinical experience at our clinic with expanded polytetrafluoroethylene grafts was evaluated with special respect to the preoperative angiographic assessment, ankle arm systolic pressure index and pulse volume recording. A total of 94 PTFE grafts were inserted consecutively to by-pass a femoro-popliteal artery segment occluded by chronic occlusive disease. Polytetrafluoroethylene (PTFE) was used when no suitable autogenous vein was available. Seventy-one grafts were inserted for limb salvage (stage III or IV). Within the follow-up period of 6 months for all patients patency rate amounted to 68%. Best results were obtained in patients with a high ASPI and a good peripheral run-off, and in patients with the distal anastomosis placed above knee.

Pseudo-aneurysm of the popliteal artery by femoral exostosis in a young child.

Exostosis is a solitary benign bone tumor frequently observed in children. It may be totally quiescent or provoke complications. We report a case of pseudo-aneurysm of the popliteal artery caused by an exostosis on the lower metaphysis of the femur in a 12-year-old boy. This unusual complication mostly reported in young males (mean age 19 years) occurs in the context of an initial trauma in half the cases. Surgical treatment is a semi-emergency requiring both bone and arterial repair. Preventive surgery should be discussed for all cases of exostosis with a risk of arterial damage due to the gravity of the potential vascular complications.

[Spontaneous regression of a sub-adventitial cyst of the popliteal artery].

We report a case of spontaneous regression of a cystic adventicial disease of a popliteal artery in a 37 years old man. The peroperative resection of the adventicia give us the histologic confirmation of the diagnostic. The cyst's content may have gone through either in the peri-arterial space or through a communication with the articulation of the knee. For us, it seems to confirm the embryologic theory for the pathogenic of this disease.

Idiopathic true aneurysm of the popliteal artery in childhood.

Non-traumatic arterial aneurysms in childhood are very uncommon and are usually associated with inflammatory or degenerative conditions. A case of idiopathic true aneurysm occurring in one popliteal artery of a 14-year-old girl is described. Geniculate artery branches arose from the sac and histological examination confirmed that it was a true aneurysm. Successful treatment by the insertion of a reversed vein graft was confirmed by follow-up years after the operation.

Percutaneous transluminal laser angioplasty versus balloon dilation for treatment of popliteal artery occlusions.

PURPOSE: To compare the immediate results, complication rates, and long-term outcomes of percutaneous transluminal laser angioplasty (PTLA) versus balloon dilation alone in the treatment of popliteal artery occlusions. METHODS: In a prospective nonrandomized study conducted between December 1994 and June 2000, 215 symptomatic patients with unilateral popliteal occlusions were treated with either dilation alone (88 patients: 52 men; mean age 62 years, range 48-83) or PTLA (127 patients: 70 men; mean age 64 years, range 49-86) using a 308-nm excimer laser followed by dilation. The average occlusion length was 10.4 cm (range 3-14). RESULTS: PTLA was successful in recanalizing 105 (82.7%) arteries, while the recanalization rate for dilation alone was only 70.4% (62/88; p=0.045). After a mean follow-up of 36 months (range 6-52), the primary and secondary patency rates were 21.7% and 50.8%, respectively, in patients with PTLA and 16.3% and 35.2% in the angioplasty group (p=0.762). The complication rates associated with both techniques were similar. CONCLUSIONS: Although initial recanalization may be better with PTLA, it does not appear to add any long-term benefit over balloon dilation alone.

Postoperative aneurysm of the popliteal artery after arthroscopic meniscectomy.

We report a case of a 14-year-old girl who underwent arthroscopic subtotal meniscectomy after a bucket-handle tear of the lateral meniscus followed by a pseudoaneurysm of the popliteal artery. A revision surgery and reconstruction of the artery with a saphena magna patch was necessary to repair the defect. At 1-year follow-up, excellent range of motion, function of the knee, and a normal quality of life was achieved.

Long-term follow-up of surgically excluded popliteal artery aneurysms with multi-slice CT angiography and Doppler ultrasound.

The purpose of this study was to evaluate the role of multi-slice computed tomography (MSCT) angiography in the follow-up of popliteal artery aneurysms (PAAs) that have been operated on. Aneurysm exclusion and progression, graft patency and graft-related complications were analyzed. Fourteen patients with 21 surgically excluded PAAs were evaluated with MSCT angiography with slice thickness of 1.25 mm. The mean follow-up time was 67 months. MSCT demonstrated blood flow in six non-excluded PAAs (24%), with an average increase in the diameter of 21 mm over time. Fifteen PAAs demonstrated no blood flow and revealed an average decrease of 7 mm in diameter. The origin of this residual perfusion was demonstrated, and collaterals were involved in five of six non-excluded PAAs. In addition, MSCT demonstrated three graft stenoses. Furthermore, two occluded grafts were visualized. Twenty-four percent of the patients after surgical exclusion of PAAs revealed residual perfusion within the aneurysmal sac during follow-up, with a significant increase in the aneurysmal size with MSCT. Moreover, evaluation of the graft patency could also be done as could demonstration of anastomotic abnormalities. Thus, MSCT might be considered as a new tool to evaluate residual collateral feeding of popliteal aneurysmal sac and could be useful in identification and localization of feeding vessels.
