Robot-assisted versus manual percutaneous vascular interventions across vascular territories: a systematic review and meta-analysis.

Robot-assisted percutaneous vascular intervention (R-PVI) has expanded beyond coronary procedures, but previous reviews were largely coronary-focused and observational. Recent randomized controlled trials (RCTs) warrant broader reassessment of R-PVI versus manual percutaneous vascular intervention (M-PVI) across vascular territories. PubMed, Embase, Web of Science, and the Cochrane Central Register of Controlled Trials were searched from database inception to January 31, 2026, following PRISMA guidelines. RCTs and observational studies including &#x2265;10 adult patients in total were eligible. Comparative studies informed primary analyses, while single-arm studies provided supportive evidence. Primary outcomes were clinical success rate and major adverse cardiovascular/cerebrovascular events (MACE) rate. Secondary outcomes included mortality rate, technical success rate, procedural time metrics, contrast volume, and radiation exposure. Random-effects models were used. Forty studies were included: 3 RCTs, 10 comparative observational studies, and 27 single-arm observational studies, comprising 3,870 patients undergoing R-PVI and 1,142 undergoing M-PVI. Comparative analyses showed similar clinical success rates (RR 1.00, P = 0.46), MACE rates (RR 0.72, P = 0.43), and mortality. Single-arm pooled estimates for clinical and technical success were 98.76% and 96.09%, respectively. R-PVI prolonged total procedure time overall (MD 15.92&#xa0;min, P = 0.01), with consistent increases in the neurovascular, RCT, and non-RCT subgroups. Fluoroscopy time was also longer (MD 1.91&#xa0;min, P = 0.04), mainly in the RCT subgroup (MD 2.83&#xa0;min, P = 0.001). In contrast, intravascular intervention time was unchanged overall and in RCTs, but was prolonged in non-RCTs (MD 8.72&#xa0;min, P = 0.006). Operator radiation exposure was markedly reduced (MD -33.97 &#x3bc;Sv, P < 0.001), whereas patient radiation exposure and contrast volume were similar. R-PVI appears feasible and safe across selected vascular procedures. Its clearest benefit is reduced operator radiation exposure, whereas lower whole-procedure efficiency remains its main limitation.

Undesirable effects of hemometakinesia induced by vascular reconstruction.

Hemometakinesia, the borrowing of blood by one part of the body for use by other parts or tissues, is a well regulated physiologic mechanism involving selective vasodilation and vasoconstriction. It has been shown, however, that diversion of blood flow following vascular reconstruction may impoverish tissues from which the blood flow is borrowed, causing ischemia in these vascular beds. Observations on 12 patients out of a group of 100 who had undergone vascular reconstruction of a limb deterioration. It is suggested that the type and site of the vascular disorder and the expected diminution of blood flow in other involved arterial circuits should be considered in selecting the most appropriate vascular surgical procedure. Searching for and recognizing the hemodynamic significance of a silent lesion in the carotid or gastrointestinal circuit or in a contralateral limb may avert a vascular crisis after the primary lesion has been successfully treated.

Infections in vascular surgery.

The frequency of postoperative wound infections after 304 vascular surgical procedures was studied. Mean age of the patients was 67 years and the male-female ratio was 5:1. Seventyfive per cent of the operations were of elective type. Wound infections occurred in 12% and was in the majority of cases caused by staphylococcus aureus. Wound infection caused prolongation of hospital stay from 11.9 to 31.3 days. A higher frequency of postoperative wound infections was found in diabetics, in patients with manifest gangrene, in patients with long preoperative hospital stay and after operations with inadequate hemostasis. Infections are potentially dangerous and in this series they caused loss of limb and life in one patient and loss of limb in one.

[Possibilities of vascular surgery in urology and nephrology].

The vascular surgical procedures most frequently applied in urology and nephrology are described. The urological aspects of the various methods are stressed and cases suitable for joint urological and vascular surgery are presented. With respect to the occlusion of the renal artery the difference between the recanalization of this vessel and of the peripheral vessels is pointed out and the importance of preserving the kidney is emphasised. The hope is expressed that by the increasing use of vascular surgical methods a more effective therapeutical possibility will be available to increasing numbers of urological-nephrological patients.

Psychiatric complications in a surgical ICU.

Pathological behavior patterns are often observed in patients in the ICU. In a Surgical ICU (SICU), 7% (22/322) of a patient population required psychiatric consultation during a 6-month period. As a group, these patients had more prolonged stays, more frequent requirements for mechanical ventilation, a higher incidence of cardiac arrest and a higher mortality rate than the entire SICU population. The psychiatrist was asked to evaluate multiple behavioral syndromes, some of which were irreversible concomitants of grave illnesses. However, with certain syndromes, psychiatric assistance greatly facilitated the resolution of problems that hampered pre- and postoperative management and the patient's eventual recovery.

Fatal retroperitoneal haemorrhage complicating anticoagulant therapy.

Eight cases are reported of extensive retroperitoneal haemorrhage in patients receiving anticoagulant therapy who subsequently died and underwent postmortem examination. No patient had an obvious source of bleeding, and in 5 cases no other cause for death was apparent. Three patients had had vascular surgical procedures: the other 5 were given anticoagulants for suspected venous thrombo-embolism. Six cases presented as unexpected circulatory collapse with rapid demise. Four patients had in addition gastro-intestinal bleeding of varying degree, with no obvious source. This acute massive type of retroperitoneal bleeding contrasts with the commoner presentations of pain, swelling, bruising and compression neuropathy: a high index of suspicion and urgent treatment are required if mortality is to be reduced.

[Postoperative cardiac arrhythmias (author's transl)].

13 male patients suffering from arteriosclerotic heart disease and/or arterial hypertension were monitored continuously before and after vascular surgical procedures using an arrhythmia computer. Heart rate, paroxysmal supraventricular tachycardias, ventricular extrasystoles, ventricular tachycardias, ventricular fibrillation and prematurity index (QnQe/QTn) were recorded numerically. Ventricular arrhythmias were detected as follows preoperatively in 12 patients, after operation in all patients, paired ventricular extrasystoles or episodes of ventricular tachycardia were found in 5 cases before and in 7 after operation, ventricular fibrillation in one case. The incidence of ventricular dysrhythmias increased significantly (p less than 0.05) early after operation, as did the heart rate during the observed postoperative period (p less than 0.001). The prematurity index dropped below 1.0 during the two days following operation. This differed significantly from the preoperative value (p less than 0.05). The incidence of ventricular extrasystoles was related to postoperative myocardial infarction and heart failure (p less than 0.01), which occurred in 6 cases, with a lethal outcome in three. Only occasionally controlled by trained staff in a normal surgical ward the "Servomed Dysrhythmiemonitor" yielded reliable numerical results during the main part of the monitored period. In two cases it led to immediate detection and rapid institution of treatment of severe tachyar rhythmias.

Fracture of the femoral neck. II. Relative importance of primary vascular damage and surgical procedure for the development of necrosis of the femoral head.

The opinion is widely held that interruption of the arterial flow through the retinacular arteries to the femoral head is the main cause of avascular necrosis after fracture of the neck. In this study the state of the vascular supply to the femoral head was assessed--prior to osteosynthesis--by means of intramedullary pressure measurements in the femoral head and neck in 72 patients with medial neck fractures. The patients were followed 2 or 3 years or until avascular necrosis became evident. The relative importance of primary avascularity and surgical technique for the development of necrosis suggests that damage to the retinacular arteries may not be the single decisive factor in the pathogenesis of femoral head necrosis. Proper fracture reduction with extensive contact between the cancellous bone surfaces and stable fixation seemed to be more important, probably because they offer the best possibilities for re-establishment of transosseous blood flow across the fracture site.

Hemodynamic observation in relation to extensive surgical treatment of patients with increased operative risk.

In 25 patients, considered high surgical risks according to clinical criteria, systemic and pulmonary hemodynamic parameters were monitored using a flow-directed pulmonary arterial thermodilution catheter before, during and after major vascular surgery. During and after the operation, hemodynamic complications were observed in 13 patients. The following conditions were dealt with: hypovolemia, increased systemic vascular resistance, and left ventricular failure in hypervolemia and in normovolemia. Tachy-arrhythmias seen in six of the patients were associated with left ventricular failure, hypovolemia or normal hemodynamics. Operation for renovascular hypertension and thoracolaparotomy carried the highest risk. Two of the patients died from primarily surgical complications.
