Popliteal vein thrombosis secondary to popliteal artery aneurysm.

Two patients with popliteal vein thrombosis secondary to popliteal artery aneurysm are described. The association of venous abnormalities in 623 reported cases of popliteal artery aneurysm is reviewed. The high morbidity from popliteal vein thrombosis would seem to justify preoperative leg venography in patients with popliteal artery aneurysm.

Popliteal artery aneurysms. Past and present.

Popliteal artery aneurysms have had an important historic role in the development of modern vascular surgery. Early methods of surgical therapy for these aneurysms are detailed in this report for a persepctive. Clinical aspects of surgical diagnosis and treatment of 35 popliteal artery aneurysms in 26 patients are also reviewed. Such aneurysms often present with varied symptoms and should be considered a treacherous disease entity since limb loss occurs in a considerable number of patients. Coexisting disease frequently complicates both the intraoperative and postoperative course of these patients. In this series of popliteal aneurysms, excision and venous autograft interposition offered the most successful operative therapy.

Summary of cases of adventitial cystic disease of the popliteal artery.

Adventitial cystic disease of the popliteal artery is explored. The results of correspondence with authors reporting this condition are elaborated upon. This has provided an opportunity to discuss the history of the condition, the findings in 115 cases which have come to the attention of the Correspondence Office dealing with this entity, and the results of treatment. A discussion of the suspected etiology of the condition is presented. The condition remains one of unknown etiology which can be treated by cyst evacuation or aspiration when the popliteal artery is patent and which is best treated by arterial reconstruction when the artery is occluded. The results of such treatment are good but are dependent upon technical excellence of the operative procedure.

Remote bypass grafts for managing infected popliteal artery lesions.

Infected false aneurysms of the popliteal artery may complicate vascular repairs for trauma or primary arterial disease. Adequate debridement and drainage are necessary if the limb is to be salvaged, but direct arterial grafting through the infected area cannot be performed safely. Vascular reconstruction can be accomplished by performing a femoropopliteal or iliopopliteal bypass through a lateral approach, then the infected artery can be removed safely through separate incisions. This technique was used successfully in managing four patients with infected popliteal artery pseudoaneurysms.

Management of popliteal artery injuries.

In a series of seven popliteal artery injuries including two concomitant popliteal vein injuries and three knee dislocations, only one failure occurred. With appropriate training of emergency medical technicians and adequate supportive services such as blood banking and arteriography, the vascular surgeon in a small hospital setting can manage peripheral vascular trauma with acceptable results.

Gray scale ultrasound evaluation of popliteal artery aneurysms.

GRAY SCALE B-scan ultrasonography is accurate in identifying and assessing morphologic features of popliteal artery aneurysms. Eight patients with suspected popliteal aneurysms had 12 aneurysms demonstrated by ultrasonography, including two not visualized by arteriography due to proximal occlusive disease and three covert aneurysms opposite a contralateral palpable popliteal mass. Half the patients had bilateral aneurysms demonstrated by ultrasonography. Popliteal artery ultrasonography is useful to: (1) evaluate suspected aneurysms in patients who cannot or should not be subjected to invasive arteriographic studies or operation; (2) confirm or refute equivocal diagnoses of aneurysms generated by arteriographic studies or physical examination; (3) detect contralateral clinically covert aneurysms or small aneurysms in patients with generalized extrapopliteal aneurysmal diseases; (4) delineate the extent of intraaneurysmal thrombus and determine exact aneurysm size in all dimensions; and (5) define a thrombosed aneurysm or one noe opacified because of limited contrast material passing through proximally obstructed arteries. The latter two uses of ultrasonography represent significant advantages over arteriography.

Popliteal artery thrombosis in a young woman, secondary to bony exostosis.

Idiopathic thrombosis of the popliteal artery in young people is exceedingly uncommon. Previously suggested etiologies are cystic adventitial disease, popliteal entrapment syndrome, Buerger's Disease, juvenile arteriosclerosis and synovial cysts. An instance of popliteal artery thrombosis secondary to compression by a bony exostosis is recorded to call attention to this unusual etiological mechanism in a 21 year old woman. Restoration of arterial continuity was achieved by endarterectomy and a venous patch graft following excision of the bony exostosis.

Efficacy and Safety of Autologous Versus Prosthetic Grafts in the Repair of Popliteal Artery Aneurysms: A Systematic Review and Meta-Analysis.

BACKGROUND: Popliteal artery aneurysms (PAAs) present a severe risk of progression to acute limb ischemia. Open surgery (OS) is the gold standard treatment; however, prosthetic grafts are acceptable in highly selected cases, especially when the great saphenous vein is not available. METHODS: We performed a systematic review and meta-analysis of studies comparing autologous versus prosthetic grafts for patency and limb preservation outcomes in patients with PAAs. MEDLINE, Embase, and Cochrane Central were systematically searched from inception through October 2024. Outcomes were pooled using a frequentist random-effects model as odds ratios, mean differences, and hazard ratios (HRs) with 95% confidence intervals (CIs) on RStudio (Version 4.5.0). Risk-of-bias assessments were performed using ROBINS-I and MINORS. RESULTS: Twenty-two observational studies were pooled comprising 9,145 PAAs in 8,370 patients, of whom 6,434 (74.51%) were treated with autologous grafts and 2,200 (25.49%) with prosthetic grafts. Follow-up ranged from 12 to 86 months. Repair with autologous conduits significantly improved long-term primary patency (HR 3.93; P < 0.001), secondary patency (HR 6.02; P < 0.001), and long-term limb salvage (HR 2.69; P = 0.044) compared with prosthetic conduits. There were no significant differences in in-hospital amputation (P = 0.36), myocardial infarction (P = 0.61), mortality (P = 0.50), 2-year primary patency (P = 0.25), 5-year secondary patency (P = 0.06), or length of hospital stay (P = 0.95). Risk of bias was classified as moderate-to-high, reflecting confounding factors inherent to observational studies and moderate methodological quality by MINORS. Despite these limitations, treatment effects consistently favored autologous grafts in both short- and long-term analyses; however, caution is warranted given the limited number of available studies. CONCLUSION: The use of autologous conduits significantly favors both short-term and long-term efficacy and safety in the OS repair of PAAs. Given the limitations of the existing evidence, further comparative studies are needed.

[Endarterectomy of the femoral and popliteal arteries].

The experience of 127 operations for endarterectomy of occlusions of the femoral and popliteal arteries in 122 patients is analyzed. The remote results were observed for 10 years. The cumulative analysis within 10 years after operations have shown 27% of endarectomized arteries to remain passable. The best results were obtained when using the gaseous method modified by the authors, for correction of short occlusions in combination with good outflow pathways. With this form of pathology 68% of arteries are found to be passable within 10 postoperative years.

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.

Transluminal angioplasty of the iliac, femoral, and popliteal arteries.

The recently developed Grüntzig balloon dilatation catheter has facilitated the performance of transluminal angioplasty. The authors used this catheter in 35 arteries supplying the lower extremities in 27 patients. Immediate relief of symptoms (claudication and rest pain) occurred in 30 vessels (86%) in 23 patients. The procedure was well tolerated by all patients. Over 90% of initially successful dilatations were patent at 3 to 10 months.
