[Aneurysms of the popliteal artery].

The 45 patients with popliteal artery aneurysms have been treated at the Institute for Cardiovascular Diseases from Belgrade, during the last 36 years. Four of them were women and 41 men, with average age of 61 years. The incidence of bilateral localization was 28%. The aneurysms have been presented with the rupture in 6 cases, with deep popliteal venous thrombosis in 3 cases, with sciatic nerve compression in one case, and with acute or chronic leg ischemia in 38 cases. Seven small asymptomatic aneurysms have not been operated. The primary major leg amputation had to be done in 8 cases due to irreversible ischemic changes. Any form of reconstructive procedures has been done in 48 cases (total or partial aneurysmal resection with graft interposition, an aneurysmal exclusion and bypass procedures). The autologous saphenous vein graft has been used in 42 cases, PTFE in 5 cases and Bovin solco graft in one case. Three patient died intraoperatively due to massive myocardial infarction. The early patency rate was 91%, and limb salvage 93%. The follow-up period was between 2 months to 16 years (men 3 years). The long term patency rate was 86%, and limb salvage 97%. The surgical treatment is the method of choice in case of popliteal artery aneurysm, due to good results, and possible complications.

[Arterial embolisms of the lower extremities].

INTRODUCTION: Embolism is one of the most frequent causes of lower limbs acute arterial occlusion [1]. Of the total number of peripheral embolism 56% of cases involve lower limbs arteries [2]. Inadequate and late treatment of the lower limbs embolism is associated with high morbidity and mortality rate. The aim of this paper was to study the aetiology of lower limbs embolism and to detect factors influencing early and late results after the operative treatment. PATIENTS AND METHODS: The study included 204 patients with 224 lower limbs embolism, treated surgically at the Institute of Cardiovascular Diseases of the Clinical Centre of Serbia in Belgrade in the period between 1993 and 1997. There were 107 (52.2%) female and 97 (47.8%) male patients. Thirty two (14.3%) patients were younger than 50 years, 64 (28.6%) were between 51 and 65, 101 (45.1%) between 66-75, while 27 patients (12.1%), were older than 75. Twenty (8.9%) patients were admitted less than 6 hours before the operation, 79 (33.3%) between 6 and 24 hours, and 125 (55.8%) more than 24 hours before the operation (Table 1). One hundred (53.6%) patients had motor and 133 (59.4%) sensor paralysis on admission. Table 2 shows arterial localization of the lower limbs embolism. The popliteal artery was involved in most cases. During the operation transfemoral arterial approach was used in 132 (58.9%) cases, while transpopliteal in 92 (41.1%) cases. Fourteen cases required bypass surgery, 43 fasciotomy, 2 intraoperative streptokinase and 4 intraoperative angiography. All patients were controlled using physical and CW Doppler ultrasonographic examinations immediately after the operation, and then one, six and 12 months, as well as every year. RESULTS: In 173 (84.4%) patients cardiac causes of embolism were found, in 8 (3.9%) noncardiac, while in 8 (3.9%) the cause could not be established. Of all cardiac causes absolute arrhythmia was most frequent. Table 3 and Table 4 show the aetiology of the lower limb embolism. The early amputation rate was 23 (10.3%) cases, while limb salvage was recorded in 174 (77.7%) patients. Of all saved limbs complete recovery was noted in 162 (72.4%) cases and peroneal nerve paresis in 12 (5.3%) cases. The early postoperative mortality rate was 27 (12.0%). Table 5 shows early results of embolectomy. The early results (limb salvage, complete recovery, rethrombosis, early reoperations, amputations rate, morbidity and mortality rate) of embolectomy were statistically significant: worse in cases when the embolus was located in the abdominal aorta and popliteal artery; in cases with a long time interval before the operation as well as in patients with sensor-motoric paralysis on admission (Tables 6-8). Of the total number of patients in 87 (56.5%) cases a late control examination was carried out. Forty nine (31.8%) patients died before the late control, while 18 (11.7%) did not come to control examination. Late recidivation of embolism was found in 3 cases. In these patients the cause could not be found, and they were treated by anticoagulant drugs.

[Differential diagnosis of deep vein thrombosis].

UNLABELLED: The incidence of deep venous thrombosis (DVT) is high in numerous surgical and medical diseases [1]. There are increasing data on higher incidence of DVT in patients with malignant and other diseases [2]. The diagnosis of DVT is not always simple since there are subclinical and asymptomatic forms of the disease [3]. Besides, there are numerous pathological conditions that imitate deep venous thrombosis [4]. METHODS: We present the results of a retrospective study over the period of January 1, 1996--June 30, 1998 at the Department of Vascular Surgery. Over that period we treated 113 patients (64 females, 49 males, average aged 60.3 +/- 7.5 years) with clinical picture of deep venous thrombosis. All patients underwent duplex scanning examinations (Toschiba SSA-100 A, 3.5 MHz and 8 MHz probes) [5, 6]. Special examinations such as angiography (8 patients), computerised tomography or nuclear magnetic resonance (27 patients) were performed in cases with unclear findings. RESULTS: True DVT was established in 91 (80.3%) patients (Fig. 1). Seven of these patients had asymptomatic phlebothrombosis. Of 12 (10.6%) patients in 9 other pathologic conditions were found (Fig. 2). This symptomatic DVT was caused by malignant diseases (5 sarcomas, 2 metastatic carcinomas, 1 lymphoma); aneurysms of common femoral artery (2) and popliteal artery (2 patients). Ten patients (8.9%) with clinical picture of DVT established by special examinations had no evidence of the presence of intravenous thrombs (Fig. 3). This pseudo DVT was caused by calf haemathoma (3), Baker's cyst (2), popliteal artery aneurysm (1), lipoma of thigh (1), psoas abscess (1), gluteal abscess (1) and acute arthritis of the knee (1). The treatment of these groups of patients was different: surgical thrombectomy, use of streptokinase or heparine (true deep vein thrombosis), tumour extraction (Fig. 4) or another surgical treatment (symptomatic phlebothrombosis) and special decompression measures (Fig. 5) (pseudophlebothrombosis). DISCUSSION: Aetiopathogenesis of true DVT is determined by Virchov's triad [3, 4, 7, 8]. The incidence of DVT in medical and surgical patients is high (30-75%). Initially true DVT may be asymptomatic in 35-70% of patients [1, 3, 8] and depended on detection methods [1, 6, 7, 9, 10]. DVT may be only a symptom of other pathological conditions [2, 3, 7]. This symptomatic DVT is mostly caused by malignant diseases [2]. Pseudo DVT or primary deep vein obstruction may be caused by external abnormalities (right common iliac artery; compression of the left common iliac vein, malignant disease, retroperitoneal fibrosis, internal iliac compression of the external iliac vein, latent femoral hernia compression of the femoral vein, masses in the thigh (large tumours, true or false aneurysms, popliteal masses/aneurysms, large Baker's cysts), changes in the wall or within the lumen of a vein as aplasia, primary tumours, intraluminal spurs [7].
