Methods: An 18 year old male patient with a 4 week history of pain, hematoma, and oedema of the left calf without previous trauma is reported. A computed tomography scan CT revealed a large popliteal artery pseudoaneurysm and its close relationship to a protrusion of the proximal tibia. Results: The popliteal artery was repaired by an external saphenous patch and the exostosis was removed. The patient had palpable popliteal and distal pulses after surgery and during the first year follow-up.
Conclusions: Tibial osteochondroma should be considered in the differential diagnosis in young patients, among the potential causes of pseudoaneurysm of the femoral or popliteal artery.

Surgical repair should be performed to restore normal blood flow with resection of the exostosis to prevent recurrence. Keywords: Popliteal artery, Pseudoaneurysm, Tibial exostosis, Osteochondroma. Popliteal artery repair in massively transfused military trauma casualties: a pursuit to save life and limb. More than before, casualties are now surviving the initial medical evacuation and presenting with severely injured limbs that prompt immediate limb salvage decisions in the midst of life-saving maneuvers.
A modern analysis of current results may show important changes because previous limb salvage strategies were limited by the resuscitation and surgical techniques of their eras. Because exact comparisons between wars are difficult, the objective of this study was to calculate a worst-case a pulseless, fractured limb with massive hemorrhage from popliteal artery injury amputation-free survival rate for the most severely wounded soldiers undergoing immediate reconstruction to save both life and limb.
We performed a retrospective study of trauma casualties admitted to the combat support hospital at Ibn Sina Hospital in Baghdad, Iraq, between and We extracted data on the subset of casualties with a penetrating supra or infrageniculate popliteal arterial vascular injury. Demographics, injury mechanism, Injury Severity Score, tourniquet use, physiologic parameters, damage control adjuncts, surgical repair techniques, operative time, and outcomes all-cause day mortality, amputation rates, limb salvage failure, and graft patency were investigated.
There was one early death. The median operative time for the vascular repairs was minutes range, minutes and included all damage control procedures. Ligation was. Popliteal artery entrapment syndrome misdiagnosed as chronic A year-old provincial rugby player complained of exercise- induced pain in both Because all of these conditions may present with pain or intermittent claudication, imaging is crucial for differentiating them and directing management.
Delayed diagnosis can lead to major complications, including acute limb ischemia. Our aim is to provide an illustrative overview of these conditions in order to make radiologists aware of them and avoid misdiagnosis for timely appropriate management. Imaging popliteal artery disease in young adults with claudication: self-assessment module. The educational objectives of this self-assessment module on imaging popliteal artery disease in young adults with intermittent claudication are for the participant to exercise, self-assess, and improve his or her knowledge of the imaging and clinical features of popliteal artery entrapment syndrome, cystic adventitial disease,and masses associated with popliteal artery obstruction.
Full Text Available True Popliteal artery aneurysm is the most common of all the peripheral artery aneurysms. We present a case of proximal popliteal artery aneurysm involvement both lower limb presented with gangrene in one lower limb and incapacitating claudication pain on the other lower limb. Full Text Available Popliteal cyst commonly presents as an ellipsoid mass with uniform low signal intensity on T1-weighted magnetic resonance images and high signal intensity on T2-weighted images. Here, we describe a popliteal cyst with unusual appearance on magnetic resonance imaging, including heterogeneous intermediate signal intensity on T2-weighted images.
Arthroscopic cyst decompression revealed that the cyst was filled with necrotic synovial villi, indicative of rheumatoid arthritis. Arthroscopic enlargement of unidirectional valvular slits with synovectomy was useful for the final diagnosis and treatment. Popliteal amyloidoma presenting with leg ischemia in a chronic dialysis patient. The authors report a case of bilateral popliteal amyloidoma causing stenosis of the popliteal artery and vein.
This patient had been treated with hemodialysis for 26 years. The diagnosis was made with MR angiography. A popliteal tumor of the right knee was resected surgically and the histologic examination showed deposition of amyloid.

After resecting the popliteal tumor, the severe leg pain and intermittent claudication improved. This report suggests that popliteal amyloid tumors should be considered in a patient undergoing long-term hemodialysis who complains of leg pain and intermittent claudication. Ruptured popliteal cyst diagnosed by ultrasound before evaluation for deep vein thrombosis.
Most popliteal cysts are asymptomatic. However, cysts may rupture, resulting in pain and swelling of the leg that could also arise from other diseases, including deep vein thrombosis, lymphedema, cellulitis, and tear of a muscle or tendon. Therefore, it is difficult to diagnose a ruptured popliteal cyst based on only a patient's history and physical examination. Musculoskeletal ultrasound has been regarded as a diagnostic tool for ruptured popliteal cyst. Here, we describe a patient who was rapidly diagnosed as ruptured popliteal cyst by ultrasonography. Therefore, ultrasound could be used to distinguish a ruptured popliteal cyst from other diseases in patients with painful swollen legs before evaluation for deep vein thrombosis.
Balloon angioplasty of popliteal and crural arteries in elderly with critical chronic limb ischemia. Objective: Elderly patients with extensive infrainguinal peripheral vascular disease and critical chronic limb ischemia CCLI are poor surgical candidates. Our purpose was to evaluate angiographic and clinical results of popliteal , infrapopliteal, and multi-level disease percutaneous transluminal angioplasty PTA in such patients. Design: Retrospective study of angiographic and clinical files in selected group. Materials and methods: Between and , 38 elderly patients aged years old mean age All patients were at high surgical risk.
One hundred and two lesions were treated by angioplasty. Immediate angiographic and 1 year clinical results were retrospectively analyzed. There were three major complications 7. After 1 year, 27 patients could be followed, five patients died during the first year of unrelated causes. Twenty-three patients Conclusions: Elderly patients with multi-level CCLI have a short patency term following angioplasty of Computer tomographic demonstration of the popliteal artery entrapment syndrome. The popliteal artery entrapment syndrome can be diagnosed by computer tomography with a greater degree of certainty than by angiography.
The advantage of computer tomography depends on the simultaneous demonstration of the position of the vessel and of the surrounding muscles and their abnormal situation. A new diagnostic approach to popliteal artery entrapment syndrome. A new method of diagnosing and defining functional popliteal artery entrapment syndrome is described.
By combining ultrasonography and magnetic resonance imaging techniques with dynamic plantarflexion of the ankle against resistance, functional entrapment can be demonstrated and the location of the arterial occlusion identified. This combination of imaging modalities will also define muscular anatomy for guiding intervention such as surgery or Botox injection. The current role of vascular stents.

The limitations of percutaneous balloon angioplasty have favoured the development and the use of vascular endoprostheses or stents. These thin-walled metal devices maintain after expansion, an optimal and constant diameter for the vascular lumen. Restenosis, dissection, abrupt closure, residual stenosis or re-opened total occlusion represent appropriate indications for stenting. A large experience with non-coronary application of stents is currently available in iliac, femoro- popliteal and renal arteries, aorta, large veins. Correlations between aorto- popliteal bolus transit speed and aortic and popliteal bolus transit time during CT angiography of aortoiliac and lower extremity arteries.
Nakaya, Yasuhiro, E-mail: y-nakaya radiol. Purpose: The purpose of this study was to investigate correlations between the aorto- popliteal bolus transit speed and aortic and popliteal bolus transit time in order to evaluate the possibility for prediction of bolus transit speed by single test injection technique. Materials and methods: Approval was obtained from our institutional review board for this study, which included 42 patients, from all of whom written informed consent was obtained.
The times needed to reach peak enhancement of the upper abdominal aorta T-aorta and bilateral popliteal arteries T- popliteal were obtained, and aorto- popliteal bolus transit speeds between the abdominal aorta and popliteal arteries were calculated. ABI was recorded for the bilateral feet. The Pearson's product-moment correlation coefficient was used to investigate the correlation between the bolus transit speed and T-aorta, T- popliteal , ABI, and patient age. Result: The respective correlation coefficients for bolus transit speed on the one hand and T-aorta, T- popliteal , ABI, patient age on the other were Conclusion: The time to peak enhancement for popliteal arteries showed the strongest correlation with aorto- popliteal bolus transit speeds, and was considered to be the most accurate predictor for aorto- popliteal bolus transit speeds.
Rupture of popliteal arterial aneurysm due to salmonella infection. We report here on a case of popliteal aneurysm and rupture that occurred over a day period and this was all secondary to salmonella infection. Computed tomography CT angiography of the extremity that was performed before and after aneurysmal rupture showed the aneurysm's rapid evolution to rupture over a short period of time. We also review the pathogenesis, clinical presentation, diagnostic approach and management of salmonella aneurysms.

Maternal and foetal mortality can be due to different causes. New risk factors are continuously described thanks to improvement in antenatal care and development in biology and cytopathology, increasing complexity in identifying high risk pregnancies. Level of risk can change all over the pregnancy. Ideally, it should be evaluated prior to the pregnancy and at each antenatal visit. Clinical examination is able to screen for intra-uterin growth restriction, pre-eclampsia, threatened for preterm labour; ultrasounds help in the diagnosis of foetal morphological anomalies, foetal chromosomal anomalies, placenta praevia and abnormal foetal growth; biological exams are used to screen for pre-eclampsia, gestational diabetes, trisomy 21 for which screening method just changed , rhesus immunisation, seroconversion for toxoplasmosis or rubeola, unknown infectious disease syphilis, hepatitis B, VIH.
During pregnancy, most of the preventive strategies have to be initiated during the first trimester or even before conception.
Prevention for neural-tube defects, neonatal hypocalcemia and listeriosis should be performed for all women. On the opposite, some measures are concerning only women with risk factors such as prevention for toxoplasmosis, rhesus immunization which recently changed , tobacco complications and pre-eclampsia and intra-uterine growth factor restriction. Popliteal lymphadenectomy for treating metastatic melanoma: case report. In-transit metastases also lead to poor long-term survival. Whereas for nodal disease only regional lymphadenectomy offers adequate locoregional control, for in-transit metastasis both local excision and isolated limb perfusion with chemotherapy plus tumor necrosis factor-alpha can be used for disease control.
In cases of tumors located in the distal region of the legs, the lymphatic dissemination most commonly observed is to the inguinal chain. Consequently, therapeutic inguinal lymphadenectomy or even selective lymphadenectomy sentinel lymph node biopsy have been recommended. On the other hand, involvement of the popliteal chain is very rare. When this occurs, popliteal lymphadenectomy should be indicated. Local excision may be the logical approach for a few small in-transit metastases because of the low morbidity in this procedure, when compared with isolated limb perfusion.
This was treated by means of regional lymphadenectomy plus in-transit metastases excision, with a good postoperative course.
