The article discusses results of surgical treatment of 82 patients with large and giant cerebral aneurysms operated in Burdenko Neurosurgical Institute (Moscow, Russia) during the recent 14 years. Special attention was given to benefits of intravascular blood aspiration (IBA) technique. This technique was proven to be very effective, allowing to clip the aneurysm in 87.8% of cases with good recovery in 41.5% and with moderate disability in 39%. Postoperative mortality was 4.9% (4 patients). The authors suggested original surgical classification of large and giant aneurysms. IBA was ineffective in cases of giant partially thrombosed aneurysms with sclerotic walls and giant aneurysms with very wide neck. These aneurysms require other surgical procedures such as embolization of ICA followed by extraintracranial bypass or high-flow bypass.

Based on his many years' experience in treating patients with lacrimal duct abnormalities and on his familiarity with the latest progress of endoscopic microsurgery of dacryocystitis, the author presents a historic analysis of the development of currently available surgical treatments of dacryocystitis in Russia and foreign countries. He reviews treatments divided into the following groups: 1) operations applying an external approach to the lacrimal sac, such as Toti's-type ones; 2) those applying an intranasal approach to the lacrimal sac, such as West's-type operations; 3) intranasal endoscopic microdacryocystorhinostomies; 4) intranasal laser microdacryocystorhinostomies; 5) transcanalicular endoscopic laser microdacryocystorhinostomies; 6) operations that recanalize the lacrimal duct; 7) medical treatments of dacryocystitis. The author emphases the merits and discloses the prospects of endoscopic microsurgical treatments for impaired lacrimal duct patency and dacryocystitis.

Reconstructive surgery was performed in 1148 patients with renal hypertension in the period from 1961 to 1996. Extracorporeal microsurgical correction with subsequent kidney autotransplantation was used in case of the lesions of the renal arteries branches. In 161 (14%) of the patients the result was unsatisfactory. The reasons of unsatisfactory results were the following: uncorrected stenosis of the contralateral renal artery (43%), nephrosclerosis of the contralateral kidney (26%), unknown reasons (31%). The long-term results have been followed up in 769 (67%) of the patients in the period for 135 +/- 4 months after the surgery. In 546 (71%) of the patients positive results persisted. The average time of symptomatic recurrence was 74 +/- 6 months after the surgery. Restenosis was the reason of recurrence in 61 (57%) of the patients. Based on these results the following recommendations are postulated: in atherosclerosis--the transaortic endarterectomy from the opening of the renal artery; in fibromuscular displasia--renal artery resection with end-to-end anastomosis; in nonspecific aorcic arteritis--bypass operations.

Vascular surgery, one of the main fundamental parts of angiology, is an important rapidly developing clinical specialty. The author discusses the experience in many thousand operations in injuries, atherosclerosis, and thrombosis of arteries and veins in the light of new advancements in plastic microsurgery and the use of laser, ultrasound, glue, and various types of vascular sutures. He suggests organizing adequately equipped vascular surgery departments and teams of emergency vascular surgery, wider training of vascular surgeons++, and discusses new methods for the reconstruction of vessels and use of vascular prostheses.
