Endovascular repair of inflammatory abdominal aneurysm: a retrospective analysis of CT follow-up.

Retrospective radiologic and clinical midterm follow-up is reported for 10 patients with inflammatory abdominal aortic aneurysm (IAAA) after endovascular aortic aneurysm repair (EVAR). At a mean follow-up of 33 months, regression of the thickness of the perianeurysmal fibrosis (PAF) and decrease of aneurysmal sac diameter was observed in nine patients. Four EVAR-associated complications were observed: periinterventional dissection of femoral artery (n = 1), blue toe syndrome (n = 1), and stent-graft disconnection (n = 2). EVAR is the less invasive method of aneurysm exclusion in patients with IAAA with a comparable evolution of the PAF as reported after open repair.

Cholesterol emboli following percutaneous transluminal coronary angioplasty as speculated by toe skin biopsy.

A 55-year-old man required hemodialysis for acute renal failure 3 days after repeat percutaneous transluminal coronary angioplasty (PTCA). Bilateral acrocyanosis and necrotic lesions of the toes occurred 10 days after PTCA. Skin biopsy samples revealed needle-shaped cholesterol crystals of the intraluminal clefts in his small arteries. He was diagnosed with cholesterol emboli presenting as blue toe syndrome. The conditions improved with anticoagulation and vasodilation, but improvement in renal function was temporary. He later required maintenance hemodialysis. Cholesterol emboli following PTCA are life threatening because they are difficult to diagnose and can cause severe complications.

Obstruction of the infrarenal portion of the abdominal aorta: results of treatment with balloon angioplasty.

Our experience in the treatment of stenoses of the infrarenal portion of the abdominal aorta with balloon angioplasty in 27 patients is reported. Clinical findings were lower limb claudication (all patients), impotence (eight patients), and blue-toe syndrome (two patients). The underlying disease was atherosclerosis in 24 patients and nonspecific aortoarteritis in three patients. Dilatation was successful in all patients. Embolic occlusions of the left common iliac artery (one patient) and left superficial femoral artery (one patient) were the only major complications. Claudication in the affected limb continued in the first patient; the second died when diagnostic angiography, performed 3 months after angioplasty, caused a severe atheroembolus. Of the other 25 patients, nine of the 10 followed up for 13-48 months and all seven followed up for 3-8 months were free of symptoms. Six of eight patients with sexual dysfunction had normal function after angioplasty. Seven patients still awaited follow-up and one was lost to follow-up. Our experience suggests that balloon angioplasty is an effective treatment of stenoses of the infrarenal portion of the abdominal aorta.

[What vascular events suggest a myeloproliferative disorder?].

Patients with polycethemia vera (PV) or essential thrombocythemia (ET) are at increased risk of arterial and venous thromboembolic events. Arterial ischemic complications occur in 24 to 43% of these patients, particularly those with cardiovascular risk factors (especially cigarette smoking). Non-atheromatous arterial thrombosis concerns all large and medium-sized vessels, particularly cerebral, limb, coronary and digestive arteries. Extensive complications have been described in patients with lower limb occlusive arteriopathy, particularly stent or bypass thrombosis, critical ischemia. Juvenile myocardial infarction or rapid postangioplasty coronary thrombosis may reveal certain myeloproliferative disorders, particularly ET. Venous thrombosis is more frequent in PV than in ET; superficial or deep venous thromboses are seen. Thromboembolic events occur in about 25-30% of the patients and account for one-third of the deaths. Mesenteric vein thrombosis, portal thrombosis, or suprahepatic vein thrombosis may occur in all myeloproliferative disorders, but the pathogenesis is not fully understood. Pulmonary hypertension may be the consequence of local thrombosis in the pulmonary vasculature or may be due to the high blood flow in the right heart cavities. Microvascular circulatory disturbance includes erythromelalgia, Raynaud's phenomenon, digital ischemia, acrocyanosis, blue toe syndrome, livedo reticularis, cutaneous ulcers or necrotic purpura. All these manifestations may precede the myeloproliferative disorder by several months.

[Syphilis in the third millenium].

BACKGROUND: For several decades the clinical picture of all stages of syphilis has been assumed to be immutable. The aim of the study was to describe the real spectrum of cutaneous and mucosal manifestations and organ changes and to ascertain whether the incidence of the disease has an increasing trend. METHODS AND RESULTS: The studied group included 92 patients (44 males, 48 females, average was 31.3 years) diagnosed in years 1992 to 1998 at our clinics. The diagnose was confirmed by a microscopic and/or serologic examination. Number of patients with the primary syphilis increased more than twice (1992 versus 1997), incidence of newly registered manifestations of the secondary syphilis has also increased (1996 to 1998), number of hospitalised patients in the stadium of syphilis latens increased at least twice (1992 versus 1996). Higher was the number of proven cases in pregnant patients: number of dead births increased twice, inborn forms of syphilis were three times more frequent. Among the newly described clinical forms the specific gastritis and specific uveitis were diagnosed. In immunosuppressed patients forms of lues maligna and the blue toes syndrome were identified. However, those forms were not diagnosed among our group of studied patients. CONCLUSIONS: During the last 10 years a significant increase of incidence of syphilis was reported in the population of Czech Republic. Such dangerous and almost explosive rise of new cases has been accompanied with increased number of inborn forms and with the occurrence of new clinical manifestations, namely in immunosuppressed patients.

Hypercoagulable states in arterial thromboembolism.

Hypercoagulable states are disorders of blood coagulation, which include deficiencies of natural anticoagulants, disorders of the fibrinolytic system, presence of antiphospholipid antibody and abnormalities of platelet function. These disorders are well known causes of venous thromboembolic disease and are being recognized in association with arterial thromboembolic occurrences with increasing frequency. The performance of standard prosthetic vascular reconstructions may result in disastrous outcomes in patients with unrecognized and untreated hypercoagulable states. From 1986 to 1990, we identified 12 patients with hypercoagulable states, six of whom presented with evidence of arterial thromboembolism. All of the patients were men who smoked and were somewhat younger than the usual patient with atherosclerosis. Their ages ranged from 41 to 62 years. Four patients presented with ischemic rest pain, one patient with blue toe syndrome and one with rapidly progressive claudication. Four patients had undergone prior vascular reconstruction and two had previous pulmonary emboli. Evaluation of these patients to identify hypercoagulability included determinations of prothrombin time (PT) and partial thromboplastin time (PTT), platelet count, antithrombin III, protein C, free protein S and total protein S levels, along with platelet aggregometry. Two patients had protein S deficiency, one had protein C deficiency, one patient had protein C and S deficiency and two patients had hyperaggregable platelets. Four patients had prosthetic reconstructions and two had autogenous reconstructions. Three of the four patients undergoing prosthetic reconstructions had subsequent loss of limb and one patient died. Only one patient with prosthetic reconstruction had a patent graft on long term anticoagulation. Both patients undergoing autogenous procedures had successful revascularization with limb salvage.

Oral anticoagulant therapy: a precipitating factor in the pathogenesis of cholesterol embolization?

The authors describe three patients who developed a blue toe syndrome after initiation of oral anticoagulant therapy. Based on these observations and data in the literature, they discuss a possible relationship. They conclude that the vascular surgeon should be aware of this possibility and that oral anticoagulants should be used very carefully in the "medical" management of cholesterol embolization.

Looped reconstruction of the internal and external iliac arteries in repair of abdominal aortic or iliac artery aneurysm with a bifurcated graft.

AIM: The aim of our study is to describe an original technique of distal anastomosis of a bifurcated graft, coining looped reconstruction, and our preliminary clinical experience. METHODS: This technique has been applied in 16 of 24 distal anastomoses of 12 patients with abdominal aortic aneurysm (AAA) and/or iliac artery aneurysm. Both the internal (IIA) and external iliac arteries (EIA) are transected and anastomosed with end-to-end fashion to reconstruct their continuity, and the limb of a bifurcated graft is anastomosed to the EIA with end-to-side fashion. RESULTS: Operative and in-hospital death, ischemic colitis, or ischemia of the lower extremities including blue toe syndrome has never occurred. All the 28 reconstructed IIAs and EIAs have been patent in 11 patients who could undergo early postoperative computed tomography scans with contrast medium. CONCLUSIONS: The looped reconstruction of the IIA and the EIA in repair of an AAA and/or an iliac artery aneurysm with a bifurcated graft is an anatomically easy and technically simple method.

Cardiovascular disorders. Diagnostic and therapeutic implications for the podiatric medical practice.

The cardiovascular system has multiple implications in the podiatric patient. The examination should begin with a complete and careful history. The physical examination should be thorough. Noninvasive evaluation should be performed as indicated with both a static and functional component. Cardiac disease should be investigated in all patients with a history or physical findings consistent with this disorder, such as blue toe syndrome, palpitations, or chest pain.

[Acute ischemia of the lower limbs. Clinical diagnosis].

Acute ischemia of lower limbs is severe: 25% lethality, 34% amputations (mean of 42 recent statistics). Initial clinical examination is the main point: it diagnoses acute ischemia, localizes the point of occlusion, picks up etiologic informations, assesses the repercussion of ischemia on the local and general status. The therapeutic decision is an emergency. Some particular aspects are pointed out: diagnostic between embolization and thrombosis, arterial spasm, distal ischemia with present pulses ("blue toe syndrom"), arterial dissections, complications of aneurysms. Prognosis depends on age, general condition, localization of ischemia, status of the limb, multiplicity or recurrence of embolization, but above all on early diagnostic and therapeutic.

Tibial arteriovenous fistula: successful use for limb salvage.

Embolization of atheromatous material from abdominal aortic aneurysms to the distal arterial circuit is a well-recognized clinical entity causing the "blue toe syndrome." A case is presented in which this phenomenon resulted in obliteration of the pedal arch and thrombosis of the tibial arteries. As a result, forefoot gangrene, severe leg ischemia and anterior and posterior compartment syndromes occurred. Salvage of the extremity required an extraordinary approach with the construction of an arteriovenous fistula between the posterior tibial vessels. The literature on the use of therapeutic and adjunctive arteriovenous fistulas and their physiology is discussed.

[Cholesterol embolism in the lower limbs].

An atheromatous aorta may be the source of micro-emboli composed of cholesterol crystals. These cholesterol emboli presumably result from dislodgment of atheromatous material occurring either spontaneously, or consecutively to a coronary angiography, an aortic surgery or even an anticoagulant or thrombolytic treatment. Even if the best known clinical feature is the "blue toe" syndrome together with renal insufficiency, the spectrum of disease caused by cholesterol emboli ranges from asymptomatic to rapidly progressive multiple system failure. Therefore cholesterol embolism is a serious complication of aortic atherosclerosis and often holds a poor prognosis. Diagnosis is confirmed by skin or muscle biopsy and fundoscopic examination. The optimal treatment remains to be established.

[Cholesterol embolism: a heavy price to pay after successful fibrinolysis].

We attribute a case of acute irreversible renal failure associated with "blue toe syndrome" and eosinophilia to a cholesterol embolism after "successful" treatment of myocardial infarction with fibrinolysis. This case shows that CE can be caused not only by invasive arterial procedures but also by thrombolytic as well as by anticoagulant treatment. In modern medicine, the importance of this often fatal but usually undetected systemic affection is increasing. For patients with serious atherosclerosis it is essential to analyze the risks and benefits before undertaking arterial invasive procedures or fibrinolysis.

[Atheromatous embolisms and cholesterol embolisms: medical treatment].

In patients with an acute arterial occlusion, identification of the type of mechanism is important, because both prognosis and treatment differ for each type. The aorta is the most frequent source of arterial atheromatous emboli. Aortic arch plaques are therefore recognized as an independent risk factor for stroke, and plaques located on the thoracoabdominal aorta embolize in the visceral arteries or limb circulation. The treatment of risk factors seems the most effective preventive treatment. When atherosclerosis is patent, an anti-platelet drug such as aspirin or ticlopidine is useful. When the embolus actually occurs, heparin avoids extension of thrombus and prevents its recurrence. Surgical treatment is logical but has not been supported by any randomized trial. Cholesterol cristal embolization evolves in 3 clinical forms: 1-the paucisymptomatic form, not diagnosed during subject's lifetime and only recognized in autopsy studies; 2-a benign form such as the blue toe syndrome or cutaneous livedo, with a spontaneous mild prognosis, and 3-a diffuse multisystemic form with a very poor prognosis. More than 80% of patients with the diffuse form die. When there is renal involvement, only 25% are still alive, with renal function after 6 months of follow up. Vascular surgery is limited to patients with aneurysms, which in themselves constitute a surgical indication. For all other patients, surgery is rarely indicated because 1-the source of cholesterol cristal embolization is not certain, 2-patients are usually too weak for a major surgical intervention, and 3-the necessary aortic clamping during surgery would induce a major risk of recurrence. Prevention is the most effective treatment because in 30% of patients, embolization is due to one of the following: anticoagulant drug, recent fibrinolysis, percutaneous angioplasty, vascular surgery, diagnosis angiography and/or coronarography. The medical treatment is mostly symptomatic: rest, warm conditions, appropriate dressing, antiplatelet drugs, hydration, and organ supply when necessary, principally to ensure renal function. In diffuse and multi-visceral embolization, either colchicine or corticosteroids adjuvant therapy might be useful Prostanoid drugs are also a possible adjuvant treatment.

Lower extremity arterial occlusions in young patients with Crohn's colitis and premature atherosclerosis: report of six cases.

Arterial occlusive disease (AOD) which is rarely described in patients with inflammatory bowel disease, is mainly associated with Crohn's disease (CD), and its etiology and natural course are unknown. We studied six patients (five women, one man) with CD and major lower extremity AOD who were treated at the Cleveland Clinic between 1985 and 1994. These were relatively young patients (age range 24-48 years) with steroid-dependent Crohn' colitis. On their presentation, five had acute onset of severe ischemic symptoms ("blue toe" syndrome in three) and one had rapid progression of claudication. All the patients had active CD and/or prior extensive bowel resections, and had no evidence of extraintestinal manifestation. Cardiovascular risk factors were smoking (n = 5), dyslipidemia (n = 3), family history of coronary artery disease (n = 3), premature menopause (n = 2), diabetes mellitus (n = 1). Arteriograms showed iliac artery involvement in all six patients and bilateral AOD in three. None of the patients had arteriographic or clinical signs of vasculitis. Five patients required arterial revascularizations, i.e., endovascular (n = 2), surgical (n = 2), and combined in one. Three patients had microscopic evidence of atherosclerosis. Lower extremity AOD in patients less than 50 yr of age and with CD may be partially related to premature atherosclerosis. Prospective screening for cardiovascular risk factors, subclinical disease, and hypercoagulability might be indicated in patients with active CD to prevent major arterial complications.

Aspirin-responsive painful red, blue, black toe, or finger syndrome in polycythemia vera associated with thrombocythemia.

Five patients with red, purple blue, or black toes or fingers due to thrombocythemia associated with polycythemia vera (polycythemia and thrombocythemia vera) in four and essential thrombocythemia (thrombocythemia vera) in one are described. The microvascular erythromelalgic syndrome of thrombocythemia was overlooked and progressed to cold blue swollen and painful fingers or black toes in three patients with polycythemia and thrombocythemia vera due to arteriographically documented occlusions of digital or large peripheral arteries with no evidence of preexistent atherosclerotic vascular disease. Concomitant erythromelalgia of the hand palm could be confirmed by the histopathological findings of arteriolar thrombotic lesions in the reticular dermis in two patients with polycythemia and thrombocythemia vera. The increased hematocrit in the presented patients with polycythemia and thrombocythemia vera contributed to the progression of the microvascular syndrome of thrombocythemia to major occlusive ischemic events of the extremities. Standard therapy with oral anticoagulants and reduction of the hematocrit to normal by bloodletting did not affect the platelet-mediated microvascular erythromelalgic, ischemic symptoms in the patients with polycythemia vera because thrombocythemia vera persisted. Complete relief of pain and restoration of the ischemic acral circulation disturbances in patients with thrombocythemia vera or thrombocythemia associated with polycythemia vera in maintained remission by bloodletting could be obtained by long-term treatment with low-dose aspirin.

[Blue toes and kidney insufficiency].

Three patients, two women aged 73 and 70 and one man aged 58 years, were known with hypertension and (or) coronary disease. They developed renal insufficiency and purple toes due to cholesterol crystal embolisation. In two of the three patients invasive procedures (femoropopliteal bypass surgery and replacement of the aortic valve, respectively) had provoked the embolisation process. Growing awareness of symptoms such as purple toes is important as the increasing use of intravascular procedures will lead to higher incidence of this syndrome with renal insufficiency as the most severe clinical complication.
