[The role of surgical embolectomy and extracorporeal membrane oxygen therapy in the treatment of massive pulmonary embolism - a review]. / Role chirurgické embolektomie arteria pulmonalis a membránové mimotelní oxygenoterapie v lécbe masivní plicní embolie - prehled.

Acute massive pulmonary embolism remains potentially lethal with mortality varying between 2553%. In the thrombolytic era, surgical pulmonary embolectomy is deemed as a rescue approach for patients with absolute contraindication of thrombolysis or its failure. However, close interdisciplinary cooperation, meticulous choice of optimal reperfusion strategy, standardization of surgical approach, and mainly the inclusion of mechanical circulatory support into the treatment algorithm have led to a drop in in-hospital mortality below 10% in the last 10 years. Nevertheless, cardiac arrest and refractory cardiogenic shock still remain independent risk factors of death with mortality exceeding 70%. Extracorporeal membrane oxygen therapy provides rapid circulatory support, end-organ perfusion and oxygenation which are essential for right-sided obstruction haemodynamic. Subsequently, optimal reperfusion strategy can be chosen or patients may be transported for it. The review highlights the contemporary role of surgical pulmonary embolectomy and extracorporeal membrane oxygen therapy in the treatment algorithm for acute massive pulmonary embolism, summarising current perspectives on the indications and contraindications for these treatment strategies and their results.Key words: massive pulmonary embolism - surgical pulmonary embolectomy - extracorporeal membrane oxygen therapy.

Endoscopic versus minimally invasive vein harvesting. Impact on leg-related morbidity in coronary artery bypass surgery: one-year follow-up of a prospective trial.

AIM: We sought to compare the impact of endoscopic and minimally invasive great saphenous vein harvesting on leg-related patient morbidity after coronary artery bypass grafting. METHODS: From February 2004 to July 2006, 120 patients underwent minimally invasive vein harvesting, and 180 patients underwent endoscopic vein harvesting for coronary artery bypass grafting. Patients were evaluated prospectively for wound-healing disturbances, residual leg edema, pain intensity and saphenous neuropathy at seven days, three months and one year after surgery. RESULTS: Both harvesting techniques were associated with a low incidence of wound-healing disturbances; nevertheless, endoscopic vein harvesting was associated with a significantly lower incidence of residual edema (12% vs 28%, P<0.05 seven days postoperative; 6% vs 19%, P<0.001 three months postoperative), pain (9% vs 20%, P<0.05; 6% vs 10%, P<0.05) and saphenous neuropathy (6% vs 23%, P<0.001; 3% vs 14%, P<0.05) during follow-ups. Endoscopic vein harvesting was also associated with a significantly lower incidence of neurological disturbances at one-year follow-up (2% vs 8%, P<0.05). Mean harvesting time (43.9+/-10.2 vs 40.6+/-15.5 min, P=0.09), conversion rate (2% vs 3%, P=0.71) and injury per conduit (0.3+/-0.1 vs 0.3+/-0.2, P=0.91) were comparable for both groups. CONCLUSION: EVH is superior to MIVH in terms of reduction in pain intensity, residual leg edema and saphenous neuropathy at seven days and again at three months postoperative. A significantly lower incidence of neurological disturbances is still presented one year after surgery.

Postoperative and midterm outcomes of minimally invasive and endoscopic great saphenous vein harvesting for coronary artery bypass grafting - a prospective analysis.

BACKGROUND: We sought to determine whether the postoperative and midterm outcomes of minimally invasive and endoscopic great saphenous vein harvesting are comparable. METHODS: From February 2004 to September 2006, 120 patients underwent minimally invasive vein harvesting, and subsequently 150 patients had endoscopic vein harvesting for CABG. Patients were evaluated prospectively for wound-healing disturbances, residual leg oedema, pain intensity and saphenous neuropathy on the 7th postoperative day and after 3 months. RESULTS: Both harvesting techniques were associated with a low incidence of wound-healing disturbances; nevertheless, minimally invasive vein harvesting was associated with a significantly higher incidence of residual oedema (28 % vs. 13 %; P < 0.05), (19 % vs. 6 %; P < 0.001), pain (20 % vs. 9 %; P < 0.05), (10 % vs. 6 %; P < 0.05), and saphenous neuropathy (23 % vs. 7 %; P < 0.001) (14 % vs. 3 %; P < 0.001) during follow-up on the 7th postoperative day as well as 3 months after surgery, respectively. Mean harvesting time (40.6 +/- 15.5 vs. 43.9 +/- 10.2 min; P = 0.09), conversion rate (3 % vs. 2 %; P = 0.71), and injury per conduit (0.3 +/- 0.2 vs. 0.3 +/- 0.1; P = 0.91) were comparable for both groups. CONCLUSIONS: Endoscopic vein harvesting seems to be superior to minimally invasive vein harvesting in terms of a significant reduction of residual leg oedema, pain intensity and particularly saphenous neuropathy in the postoperative and midterm follow-up.

[Endoscopic radial artery harvesting for coronary artery bypass grafting: first experience]. / Endoskopický odber arteria radialis pro revaskularizaci myokardu. Popis techniky a první zkusenost.

BACKGROUND: Radial artery is widely accepted for surgical myocardial revascularization due to reported better long-term patency than venous grafts. Endoscopic radial artery harvesting (ERAH) represents a modern method associated with reduction of post-harvesting complications in comparison with the traditional radial artery harvesting. METHODS: From October 2005 to March 2006, ERAH was performed in a group of 10 patients employing the Vasoview 6 system (Guidant, Europe S.A., Belgium). Patients were evaluated on 7th postoperative day for wound healing disturbances and neurological complications. RESULTS: The mean age was 62.7 +/- 11.3 years, male patients dominated (60%) and 5 patients (50%) suffered from diabetes. All 10 radial arteries were successfully harvested, no conduit was injured. No conversions were made from ERAH to traditional technique. The mean harvesting time was 44.9 +/- 8.2 min (range: 32-62) and the mean time of forearm ischemia was 56.7 +/- 9.3 min (range: 42-74). The mean length of the grafts was 20.3 +/- 2.2 cm. The small local haematoma was recorded in one patient (10%). Neither wound disturbances such as wound infection, wound dehiscence, skin necrosis, nor neurological complications were recorded in our group of patients. CONCLUSION: ERAH is a safe method associated with a significant reduction of particularly neurological complications associated with traditional radial artery harvest. Full-length radial artery conduits were obtained with improved cosmetic result and patient's satisfaction.

[Pulmonary trombendarterectomy in the patient with the symptoms of massive pulmonary embolism: case report]. / Trombendarterektomie plicnice u nemocného s klinickými známkami masivní embolie plicnice: kazuistika.

The case-report of a 57-year-old patient with the symptoms of massive pulmonary embolism is presented. The patient was admitted to the hospital in the cardiogenic shock, ventilated and with high dose of inotropic support. It was impossible to find out the exact data from personal history. The patient was operated on urgently. The chronic occlusion of the right pulmonary artery due to the chronic tromboembolic disease was found out. Thromboendarterectomy of the pulmonary artery was successfully performed. Three month after operation the patient is in excellent clinical condition almost without any functional limitation. Some atypical features of this case are stressed in the discussion: the urgency of the operation for chronic tromboembolic disease with unilateral involvement, which simulated pulmonary embolism and operation in mild hypothermia without circulatory arrest.
